GEORGINA COLE LIBRARY FEASIBILITY STUDY
I. EXECUTIVE SUMMARY
Background: The Carlsbad Library Master Plan, completed in 1986, provides the
framework for implementation of the City of Carlsbad’s Growth Management
Standards for Library Services. The Growth Management Plan Standard for
libraries is 800 square feet per 1,000 population. According to Planning
Department analysis, maximum build-out to the Growth Management Plan Limit
WOI i!d require 101,620 square feet of library space. The Library Master Plan calls
for the development of library resource centers in both the north and south areas of
the City to achieve geographical parity in access to resources.
The construction of the new Carlsbad City Library, scheduled for completion in
summer 1999, represents the first phase of this plan and will create 64,000 square
feet of library space, including central technical services and administrative
facilities for the two-library system.
The second step in the implementation of this plan involves renovation and addition
or new construction at the Georgina Cole Library site. An initial feasibility study for
the Georgina Cole Library site was prepared in 1990. That study defined the library
program and proposed alternatives for implementation in 1998. The purpose of the
current study is to update the building program and to look more closely at
alternative approaches to meeting the City of Carlsbad’s long term library service
needs at the Georgina Cole Library site.
Building Program: The Building Program developed by Consulting Librarian
David Smith and appended to this report provides for a scope of public library
services at the Georgina Cole site commensurate with the public library services to
be provided at the new Carlsbad City Library. The building program reflects
current trends in planning for public libraries including:

In addition to the core library services the Cole Library buiiding program provides
for the City’s Genealogy and Local History collections, for the Adult Learning
Center and for Public Meeting and Conference Rooms. The building program
indicates that a facility of 45,155 square feet is required. Together with the new
64,000 square foot Carlsbad City Library this will meet the City’s Growth
Management Standards for library services.
Building Analysis: The existing library building was visited and construction
drawings reviewed by a project team of architects, structural, mechanical, and
electrical engineers. The findings are as follows: 0

current building code life safety standards.
The original mechanical system is still in place and incurs high
operating costs in terms of maintenance and system efficiency.
The building is not in conformance with current energy codes. It is
minimally insulated, also contributing to high operating costs.
The electrical system is at full capacity and will not allow for
increased loads.
The building lacks communications infrastructure to support current
and proposed library information networks.
The building does not have an automatic fire sprinkler system and
the fire protection system does not meet current code requirements.

The extent of renovation required to allow for the implementation of the library
program is comprehensive. To provide a facility capable of meeting the library’s
operational requirements over a projected 30 year life span will require demolishing
the bulk of the existing structure and making limited use of existing slabs and
foundations.
While incremental steps of renovation may allow interim use of the existing facility,
this does not represent a feasible approach to meeting the building program.
Incremental renovation will incur substantial penalties of 1) duplication of
construction effort in subsequent phases, 2) repeated interruption of library

The extent of renovation required to meet the City’s long term objectives indicates
that replacement of the building with new construction is a strongly competitive
option. This is borne out in the cost analysis which follows.
Site Analysis: The existing site is well located and is very visible. The extent of
City-owned lots allows suifficient site area to accommodate the building program
and required parking. A proposed facility of 45,155 square feet will require 226
parking spaces at the City’s ratio of 1 space per 200 square feet of library.

Projecf Alfernatives and Cost Anafysis: Three site development approaches
meeting the goal of constructing the library program on this site are analyzed, as
well as an interim improvements alternative.
Project Budgets for each Alternative are presented by cost consultant Construction
Analysts Incorporated. Estimates are based on engineers’ reports, site plan
drawings, and construction specifications similar to those used for the Carlsbad
City Library currently under construction. Off-site work for street improvements
and utilities relocation are included as a separate line item. Related project costs
including library furnishings and equipment, testing, permit and design fees,
owner’s management costs, public art program, and owner’s project contingency
are included. Construction costs are escalated to reflect a July, 1999 bid date.

addition would be similar to Alternative B. Alternative A requires temporary
relocation for construction, and also for the subsequent addition. The scope of
renovation work is extensive, including demolition of all superstructure down to
the level of existing slabs and foundations. The future addition will remove and
reconfigure some of this work at the point of connection.
Total Project Budget: $7.9 M
Alternative B: Renovation and Addition to meet the Budding Program
(45,155 Square Feet). This alternative requires temporary relocation of the
library during construdion. The scope of renovation work includes demolition of
all superstructure down to the level of existing slabs and foundations. The
costs of this work are equal to that of new construction, and additional costs
are incurred for temporary relocation.

II. LIBRARY PROGRAM SUMMARY
Planning Background
The Georgina Cole Library has served as the City of Carlsbad’s primary location
for library resources for the last 31 years. The construction of the new Carlsbad
City Library, scheduled for completion in summer 1999, implements the first step of
a library services plan which addresses the City of Carlsbad’s Growth Management
Standards for Library Services. The Library’s Master Plan, completed in 1986,
calls for the development of library resource centers in both the north and south
areas of the City to achieve parity in access to resources. The second step in the
implementation of this plan involves renovation and addition or construction of new
facilities at the Georgina Cole Library site. A feasibility study for the Georgina Cole
Library site was prepared in 1990 and defined the library program and alternatives
for projected implementation in 1998. The purpose of the current study is to
reassess the building program and to analyze alternative approaches to meeting
the City of Carlsbad’s long term library service needs at the Georgina Cole Library
site.
The Library Trends and Library Program Summary were developed by Consulting
Librarian David Smith in team with the Carlsbad City Libraries staff. Interpretation
of the Growth Management Plan was provided by the Carlsbad Planning
Department. The entire Program Document is appended to this report.

The Growth Management Plan standard for library construction as amended by the
City Council on April 22, 1997 reads: “800 square feet per 1,000 population must
be scheduled for construction within a five year period or prior to construction of
6,250 dwelling units, beginning at the time the need is first identified.” The library

Public Library Trends
Over recent years a number of trends have been noted in both local and national
studies which must be taken into account in planning for new public library
facilities.
1. The impact of information technology on public library space has resulted in
substantial increases in square footage needed over space planning formulas
in general use just a decade ago.

Program Layout Diagram
The Building Program recommends that all library public services with the
exception of independently staffed areas such as Genealogy and Local History and
the Adult Learning Center be located on one floor level for most effective staffing.
The total area of these functions on the main level is approximately 32,000 square
feet. This means that roughly 13,000 gross square feet will be the maximum
desired on the second level. This space should be in one contiguous area for
staffing and flexibility in use over time.
The program layout diagram indicates the relative size and preferred adjacency of
the primary elements of the building program. The diagram indicates the desired
zoning of the program by floor level and with respect to public access. This
diagram defines the basic areas used in the analysis of alternatives in this report.

111. ANALYSIS OF EXISTING FACILITY
Construction Type and O~scupancy Group: The building construction type would
be best classified as Type Il-Non Rated under the current code. (Title 24 1995
California Building Code). The first level has an area of 16,280 Gross Square Feet
(GSF) inclusive of the enclosed outdoor reading court. The second level totals
8,072 GSF, for a total of 24,352 GSF. Library use is typically classified as a Group
B occupancy. Meeting rooms within the library housing less than 300 occupants
are classified as a Group A-3 occupancy, and typically total less than 10% of the
total area. The allowable area for the Type Il-N construction type given a Group B
occupancy and allowances for two stories and 40’ separation from other structures
on all sides is 48,000 square feet.
An automatic fire sprinkler system is not required if the building is less than 48,000
GSF but it is recommended for library occupancies for the protection of building
contents.
Exiting: The second level areas each have two exits as required, however the exit
stairways do not conform to current standards and do not provide areas of refuge
for evacuation assistance as required.
Accessibility: Public toilet rooms have been remodeled to meet the requirements
of Title 24 and the ADA. Vertical circulation including stairs and elevators do not
conform to current standards and will require replacement.

0 Program Analysis
Column Grid and Shear IValls: The building has a 25’x40’ column grid which
allows a fair degree of flexibility for library layout. For planning new facilities a grid
in the range of 30’x35’ is recommended for greatest flexibility and space efficiency
in laying out shelving and seating to ADA standards. Shear walls were located in
response to the initial library functions and now limit the ability to open up
contiguous spaces.
Floor to Floor Height: The existing floor to floor height and floor to roof heights
severely constrain the ability to renovate or add to this building. Existing floor to
floor heights are IO’ at the south end and 13’ at the north end. Existing floor to roof
heights are 9’ at the soutlh end and 11’ at the north end. This results in ceiling
heights of 7’-6” and 8’ in some areas. This is inadequate for public library areas.
Ceiling heights will be further reduced by the need for additional structural

requirements, and the addition of a fire sprinkler system.
Recommended floor to floor height for a new multistory library is 14’ to 15’. This
will accommodate building systems and allow a ceiling height of 9’-6” to 10’ as
recommended for visibility, lighting and air distribution in large spaces.
Second floor Areas: The second floor of the existing library is composed of two
separate areas with no connection between. The 4,400 square foot north
mezzanine is 13’ above the first floor slab, the 3,000 square foot south staff work

Building Envelope Analysis
The Library building was constructed in 1966 to the plans of architect Robert
Melvin. The design is derivative of late International Style institutional architecture
as manifested by practitioners such as Edward Durrel Stone and Minoru Yamasaki.
The building is lightly decorated with tile fascias and masonry screen walls.
Expansive glazing and a well maintained landscape contribute to an integration of
0 0
0 interior and exterior environments.
0 0 e

Thermal Assemblies: The construction drawings indicate 2” rigid roof insulation
(R-6) but do not indicate insulation at exterior wall assemblies of concrete masonry
units (R-I to 1.5) and at exterior wall assemblies of steel studs with exterior stucco
and interior portland cement plaster (R-I to 4). These values are fairly typical for
the date of construction aind represent a significant addition to operating costs.
Glazing: The glazing indicated on the construction drawings varies from 5/16” to
3/16” depending on the opening sizes. Several of the openings are very large. All
glazing is single pane and is neither tinted nor filmed for reduction of heat gain.
The glass does not appear to be tempered as would be required by current codes
given the existing opening sizes. It is strongly recommended that the existing
glazing strength be identified and replaced or reinforced as necessary in future
maintenance or renovation of the building.
Roof Membrane: The roof membrane is an aggregate-ballasted multi-ply built-up
roof installed in approximately 1983. It has been repaired intermittently since then.
There are no apparent leakage problems currently but the installation is
approaching the limit of its expected life cycle.

The letter from Blaylock Engineering Group attached in the Appendices describes
the updated structural analysis of the existing building. The structural analysis
expands upon the following key points:
Current seismic force level requirements are 38% higher than the force
levels required in the code in effect (1966 UBC) when the building was
constructed.
Current code lateral force levels greatly exce-,d the capacity of the
cantilever column system at the raised roof areas. 0 The north mezzanine floor diaphragm and system of seismic collector e beams and drag connections is inadequate by current standards. * Existing concrete block shear walls are inadequately reinforced and e have inadequate diaphragm drag connections. 0 Existing non-structural masonry screen elements represent a falling 0 hazard in a seismic event and require additional bracing and
repair/replacernent of rusted framing elements.
Thin cantilevered-slab edges around the perimeter of the building
require repair or removal.
Existing exit stair railings require repair or replacement due to corrosion.
Structural improvements to bring the existing upper floor and roof
structure into compliance with current codes necessitate doubling the
amount of existing shear walls.

The library has long operated with reduced shelving in the upper floor areas due to
limitations in dead load recommended previously for these areas. Full renovation
of the building to current code standards for library use on two floor levels will be
most economically accorriplished through the demolition and reconstruction of
virtually all superstructure, including roof, mezzanines and masonry shear walls.
New second floor loads and areas can be designed to avoid conflict with existing
footings which may be undersized for the increased loads. Re-use of shear wall
footings is possible, but is not recommended as it may constrain the library layout
significantly. A full renovation may save between 33% and 50% of the cost of
foundations and slab on grade for a new structure.

With the exception of the cooling tower, all of the primary components of the
building Heating, Ventilating and Air Conditioning system are,over 30 years old and
have exceeded their useful life by industry standards. The existing cooling tower
has a useful life of approximately 10 years, which is less than the planning horizon
of the current project. The system was not designed to current standards of
energy efficiency and is no longer performing at peak efficiency. The operation of
the building incurs substantial costs in energy usage and ongoing maintenance.
Building plumbing is in satisfactory condition. Existing domestic water, sewer and
gaz service supply lines are located immediately to the east of the building and will
require protection/relocation during construction. Resizing of these service lines
may be required by expansion of the program areas.
There is no fire suppression (automatic sprinkler) system in the building. The
building contains a heat detector fire alarm system. There is no fan shut-down
capability in case of fire. The system requires a new fire alarm control panel to
meet current codes. An automatic sprinkler system may not be required by code
but is recommended for the purposes of life safety and protection of library
materials. A dry pipe system may be considered for areas containing irreplaceable
or extremely rare materials. The existing building does not afford locations or
adequate ceiling clearances for a concealed sprinkler piping system.

Power, Lighting and Communications Systems
The electrical systems report provided by Van Buuren Kimper & Associates
Engineers is included in the Appendices to this report. The findings of the report
can be summarized as folllows:
The electrical service feeder is not adequate to support any future building
expansion or modification. The existing transformer appears to be undersized for
The main electrical room does not meet current SDG&E design standards and
requires work to relocate utilities including water piping, fire alarm panel, and
telephoneldata panels. The main switchboard does not have the capacity to
support expansion. Existing panel boards are not suitable for future building
expansion or renovation.
The energy expended to maintain current lighting levels exceeds the current Title
24 lighting energy allowance of 1.5 watts per square foot by more than 300%
(existing lighting is 5 watts per square foot). The lighting system does not take
advantage of conservation methods such as daylighting, occupancy sensors, multi-
level switching and time control.

Exterior lighting should be removed and replaced with new energy efficient
luminaires capable of providing an average illumination level of 0.5 foot candles.
Existing telephone and data systems need a separate entrance room and a
building-wide system of cable management to support current library technology
and to allow for future modification. Currently, expansion of library information
networks is limited by the lack of communications infrastructure such as cable tray
and underfloor cable access.
A new fire alarm system is recommended for the existing building to conform with
national codes, the ADA, and City of Carlsbad Fire Marshal criteria.

e
The extent of renovation required to allow for the implementation of the library
program in this building is comprehensive. Full renovation with this objective in
mind requires demolishing the bulk of the existing structure and making limited use
of existing slabs and foundations.
Incremental steps of renovation may allow for interim use of the facility but do not
achieve the City’s program objectives in a cost-effective or service-oriented
manner. Incremental renovation will incur substantial penalties of I) duplication of
construction effort in subsequent phases, 2) repeated interruption of library
services for construction activity and related costs of temporary facilities, 3) higher
construction costs associated with phased work, and 4) the creation of an end
product that does not allow the most effective provision of library services.
The potential steps of incremental renovation are interrelated but can be grouped
into three general categories as follows:

Provision for Program Objectives: The scope of building systems
expenditures begs the question of aligning these improvements with the
long-term planning for library services - Le. all major building systems
may be renewed but no significant provision for future growth will have
been made. Meeting the library’s long term program needs and
creating the potential for future addition requires major structural
reconfiguration to eliminate the constraints of shear walls and existing
floor to floor heights.

IV. SITE ANALYSIS
0 e 0 e
Extent of City Owned Property
The Library and the City Hall are located on a single legal parcel. The library
parking area occupies the two parcels immediately to the east. The city owns the
parcel immediately adjacent to the north of the parking lot. These parcels provide
adequate site area for library construction and parking, if the alignment of the
corner of Laguna Drive arid Elmwood Street can be adjusted to obtain greater site
width. The city owns several parcels on the opposite side of Laguna Drive. These
are used for the Carlsbad Arts Office and for a neighborhood gardens program.

Redevelopment of the City property for the Library may require consolidation of the
four contiguous city parcels into one legal parcel. In addition, it may be desirable
to subdivide the single parcel which contains both the Library and City Hall, so that
the Library becomes the sole use on a single parcel at the conclusion of the
project.
Topography
The Library sits at the top of a steep terrace 15’ above the City Hall site with a
finish floor elevation of approximately 123’. The Library parking area slopes uphill
22’ to the east property line which has an elevation of 145’. The rate of elevation
gain increases as one moves east, from a slope of 1:40 adjacent to the Library
increasing to 1 : 15 at the eastern property line. Carlsbad Village Drive continues to
ramp up to the east, making site access difficult from the east end of the site.

The City Hall complex lies’ immediately to the west. The library adjoins public rights
of way to both the north and south. The library parking area is bounded by
residential properties to the north and the east. The City Hall is adjacent to the
Interstate 5 on-ramp, and the site is linked to Carlsbad Village to the west of the
freeway by Carlsbad Village Drive. The Library site marks a transition point from
these commercial and institutional areas to the primarily residential areas to the
e
e e east.

The City-cwned lot immediately north of the parking lot is zoned R-I -1 0000. The
24’ height limit in this zone would preclude two-story above grade development for
the library on this lot, due to the need for 15’ floor to floor height. The library and
related parking is a conditional use and would require application for a Conditional
Use Permit and associated reviews. Alternatively, application for change of the
General Plan zoning to reflect the consolidated parcel boundaries may be made.

Summary of Project Reviews: Entitlement for library site development will require
Parcel Map changes for lot consolidation (Administrative Decision), street right-of-
way vacation (City Council approval), and General Plan Amendment for zoning
change at the consolidated parcel (City Council approval at quarterly meeting). The
General Plan Amendment will also require a Local Coastal Program Amendment to
Land Use. Coastal Commission action is required once it is acted on by the City.
A negative Environmental Declaration is anticipated.

e these are both local streets. The existing service access location should be
abandoned due to backing and turning difficulty at Carlsbad Village Drive. Service
access may be best accommodated from Laguna Drive adjacent to the City Hall
parking lots, or alternatively from the public parking area.
Parking
The City of Carlsbad parking requirement for libraries is one space per 200 square
feet of building area. The library currently has 97 parking spaces located in the lot
immediately to the east. E3y the current standard the exicting library (24,600 SF)
needs 26 additional spaces to meet the required 123 spaces.
Realignment of the Laguna Drive/Elmwood Street Intersection
The realignment of the Laguna Drive/Elmwood Street intersection is desirable to
remove the ‘bottleneck’ in the center of the library site. This narrowing occurs
immediately to the east of the existing structure in the area which is most favorable
for addition or new construction due to its relatively flat topography and the
minimization of impacts to residential neighbors. The realigned intersection would
cut into the corner lot currently occupied by the Carlsbad Arts Office. After review
of street realignment alternatives, it is clear that the termination of Laguna Drive
and Elmwood Street in cul-de-sacs meeting City Engineering Services criteria is
the most feasible approach to facilitating site development.
Street Improvements at Laguna Drive
Laguna Drive is currently a 40’ wide unimproved (lacking curbs, gutter, sidewalks)
right of way. Redevelopment of the City property will require street improvements
including an expanded 56’ right of way and installation of curbs, gutters and

Vacation of Right of Way spur at Carlsbad Village Drive
At the west Library parking lot entrance the Carlsbad Village Drive right-of-way
contains a spur which aligns with Elmwood Street to the north. This appears to be
‘left over‘ from a previous vacation of Elmwood Street. This spur encumbers the
site in a similar fashion to the Laguna Drive/Elmwood Street intersection and it is
desirable to vacate this small area as well. This spur occurs in the most favorable
site location for addition or new construction and will have an effect on the
calculation of yard setbacks, which will constrain the building footprint substantially.

0 Relocation of water, gas and sewer mains, which bisect the site, is required under
several different development scenarios. These mains align with Elmwood Street
and connect to mains located in Carlsbad Village Drive. Relocation will be required
a) for the realignment of the Laguna Drive/Elmwood St. intersection, b) for addition
to the existing building footprint (Alternative B) and c) for new construction in the
most favorable site location (Alternative C). Relocation of the gas main should be
coordinated with SDG&E. Existing overhead power lines at Laguna Drive and
Elmwood Street should be relocated underground in this area as well.
Relocation of Carlsbad Arts Office Structure
Relocation of the Carlsbad Arts Office will be necessary to accomplish the Laguna
Drive/Elmwood Street realignment. The structure is a converted single story slab-
on-grade dwelling. The structure cot!ld be relocated to one of the adjacent city-
owned parcels and its use maintained. There is a significant benefit to the
adjacency of the Arts Office and the Library, particularly if jointly bet ieficial
developments such as a sculpture court can be accomplished in the site plan.
Relocation of the existing structure is included in the cost analysis as a baseline.
Further project planning should include a more detailed feasibility study of
alternatives for the Arts Office. These might include creating space within the
library building or providing a new structure on-site more amenable to Arts Office
programs than the relocated house structure.

Alternative A provides a baseline for comparison to the alternatives which meet the
City’s long term requirements. The intent of Alternative A is to facilitate the future
implementation of the full program by comprehensively reconstructing the existing
structure and building systems in the short term, to allow for future addition. The e proposed improvements provide for a long term service life for the renewed facility. 0 This alternative includes construction of a full second floor with a floor to floor 0 height of 13, and construction of a new roof structure with a floor to roof height of 0 15’. The resulting split of functions onto the two floors does not optimize the 0 program, but provides the maximum usable space in the interim.

* VI. COST ANALYSIS
Cost Analysis of Alternatives A, B, and C was prepared by Construction Analysts,
Inc. based on project drawings and descriptions. Costs for new work reflect the
specifications employed at the Carlsbad City Library currently under construction.
The scope of renovation work in Alternatives A and B reflect the analysis of the
existing structure prepared by the architects and engineers and assumes
substantial demolition of the existing structure with partial re-use of slab and
foundations as described iin this report.
Costs for off-site work are itemized including the termination of Laguna Drive and
Elmwood Street in cul-de-sacs, the relocation of the Carlsbad Arts Office, and the
relocation of utilities mains on the library site to avoid the building area.
Construction costs are escalated to a July, 1999 bid date. Additional ‘soft’ project
costs are budgeted based on the City’s experience at the Carlsbad City Library.
Current estimates for library furnishings and equipment.
The Project Budget for Alternative D (interim Improvements) was not estimated
based on scope of work but reflects the sum of the Capital Improvement Projects
budgets already allocated for 1998-99: $349,750 and 1999-2000: $1,241,000.

CARLS6AD CITY LIBRARIES
COLE LIBRARY BUILDING PROGRAM
0 June 1998

e Prepared by:
David R. Smith, Consulting Librarian
and the e Carlsbad City Library Staff

0 0 INTRODUCTION - BACKGROUND

The basic purpose of a library building program is to translate the library resource needs of the
cornmunity served into the capacities and required building spaces for these resources and related activities which the new expanded library building will need to provide. A major
component is the collection of library materials -- print, non-print and electronic. To facilitate
accless to these materials requires a variety of types of shelving and seating and equipment
stations, as well as the necessary staff to assist in their use of the materials and to facilitate thc
circulation of materials for use outside of the library.
The Cole Library will offer two unique services. In addition to the basic resources and services
comparable to those offered in the new Carlsbad City Library, the Genealogy and Local History
seclion, which is a popular regional resource that is already established in the Cole Library, will
be enlarged and enhanced in order to meet the growing interest in these resources. The Adult
leaming Program, which IS now located in rental space a short distance from the Cole Library,
will elso be housed in the new expanded library and the training, tutoring and teaching areas
substantially improved. In developing the library building program, the resource capacities of al
of these, as well as basic library services, have been identified and translated into specific
space allocations for the new expanded library.
The assessed library needs for riorth Carlsbad and related capacities have resulted in a gross
library building area of approximately 45,000 square feet. This represents an increase of
approximately 20,000 square feet over the space available in the existing Cole Library building.
The following summary tables provide detail and documentation of the projected library
materials collection and the shelving required. The table on seating provides the breakdown on
type and location of seating. The table on equipment identifies all of the computers and other
equipment to be used by the public and staff in the library. There is also a table outlining the
staff work areas and service points. All of this information is consolidated in Table A which
summarizes all of the capacities and documents the square foot areas required.
The planning related to the Cole Library actually began in the late 1970’s and, in 1985, a
detailed study of public library needs resulted in “A Strategic Plan for the Carlsbad City Library
Facility.” This master plan identilied the need to provide for an ultimate built out population of
135,000 and that the bi-nodal nalure of the development and population distribution in the city
would require two major facilities -- one south and one north. The plan adopted also
established a library building standard of .8 square feet per city resident as a guideline to the
provision of library space. Planning discussions led to establishing the size of the Carlsbad City
Library in south Carlsbad at 64,000 square feet. At the same time that this was accomplished,
there were several summary library building programs prepared for the Cole Library which
ranged from the present 24,500 square foot to a 50,000 square foot facility. Based on the
needs and demographics of the developing population, approximately 60% south and 40%
north, and the built out standard, a minimum square footage for the Cole Library was
established at 44,000 square feet.
In the spring of 1998, the 1990 Cole library building expansion program for 50,000 square feet
was reviewed in-depth by members of the library staff and the consulting librarian. In
conju,nction with the architects preparing a study of the Cole Library building, an updated library
building program was prepared which details the needed library building of approximately
45,000 square feet. A basic premise of the planning for the new expanded Cole Library building
is thait the resources available and the basic library services will be comparable to those which
are available at the south Carlsbad City Library.

0 Public Library Trends
0 0
Over recent years, a number of trends have been noted in both local and national sudies which
must be taken into account in planning for new public library facilties.
1. The impact of technology on public library space has resulted in substantial increases in
square footage needed over space planning formulas in general use just a decade ago.

There has been an unprecedented increase in materials being published and
new formats being created. Computers and other technologies have made it far
easier to create and to publish information and creative works. The printed page
remain the primary rneans of access for most library materials.
While electronic databases may result in a reduction in the amount of print
reference materials, back issues of magazines and newspapers, government
documents and other specialized materials, public libraries are finding it
necessary to provide increasing numbers of computer stations in order to
maintain adequate access to these materials. Whereas, a number of individuals
can simultaneously access a print set of an encyclopedia, only one person per
computer station can access the same database reference tool.
The library staffs increasing role as facilitators in the use of technology requires
the necessary public service and related workstations to accomplish.

Technology has served to increase, not reduce, the space needed within public libraries.
There is a high correlation between computer ownership, purchase of books and other
materials and heavy library use. These activities serve to complement and enhance one
another. Mega bookstores and libraries are growing and flourishing side by side.
Public libraries are "destination points" for many people seeking a place to spend their
time productively in a safe and hospitable environment. In many communities, the
library has become a major social, informational and recreational center for all age
groups. Mature citizens, particularly men, are living longer and have more leisure time.
Family use of public libraries facilities is increasing.
School library resources are in a serious decline -- collections, trained staff and
adequate space. Students, particularly K - 12th grade, are relying more heavily on the
public library for both print and non-print materials to support their studies.
Recent public surveys conducted on both a local and national basis find that the library
user's highest priorities are for improved, larger collections of print materials, access to
computers, other new technologies and improved, larger library buildings.
These trends have been taken into account in the updating of the library building program
requirements for the Cole Library. The provision of adequate library building space and a
functional, flexible layout and design will permit the new expanded Cole Library to respond
satisfactorily to the needs of the northern residents of the City of Carlsbad, both now and well

Table! A - Summary of Space Allocations. Shelvina. Equipment and Staff Workstations
This consolidates the information fram the following tables in a detailed table which illustrates the
capacities for the library collections, seating, equipment and staff work areas and the space allocations
required.
Table 8-1 - Library Materials Collection - CurrentlProiected
These figures show the Cole Library circulating collection, growing to an estimated 175,550 items. In
addition, there are substantial magazine, reference and special collections such as Genealogy and Local
History -- 36,000 items.
Table 8-2 - Shelvinn Detail for Maior Collections
This table indicates the numbers of shelves and shelving units required for major collections. The amouni
of shelving shown is that needed to contain the portion of the collection which is not checked out.
Table C - Public Seating
This table illustrates area-by-area the quantities and type of individual and group seating. In the library,
there are 196 individual seats, at tabiles, equipment stations and lounge seats and 152 seats in meeting or
program rooms. In addition, there are 62 user seats in Genealogy and Local History and 71 seats for
students and tutors in the Adult Learning Program Area.
Table D - Staff Workstations/Offices
This represents stations and offices where library staff will be working, but not numbers of staff since a
ltclmber of stations such as check-out computers, copiers and work tables are used by many staff
members. There are 40 staff workstations in the expanded new library, 7 workstations in the Adult
Learning Program and 8 workstations in Genealogy and Local History. A police substation, with a
workstation and restroom, has also been proposed.
Table E - Comouter, Communicationls and Office EauiDment
This table documents the type and quantity of the equipment to be installed in the building, the principal
user, public or staff, and the general location. There are approximately 61 computer stations in the
expanded new library -- 41 for public use and 20 for staff assistance and support service activities.
In addition, there are 18 student and staff computer stations in the Adult Learning Area and 35 microfilm
and computer stations in Genealogy and Local History.

The attached table shows the 2002 projected maximum collection size of approximately 177,400 items,
the Genealogy (35,000) and Local History (1,000) Collections of 36,000 print items, plus microforms.
These projections were made by the Carlsbad City Library Collection Development Librarian. This may be
subject to further discussion and refinement.
In developing this initial information, certain provisions or assumptions were made.
1.
e
The maximum projected circulating collection size for the library is approximately 175,550 items.
exclusive of microfilm, CD-ROMs, magazines, newspapers and reference materials.
The circulating collection will be approximately 10% non-print and 90% print.
The distribution of the circulating collection will be approximately 42,750, 24%, children's materials
and 132,800, 76%, adult materials, based on projected allocations.
The library will house a reference collection -- 3,900 items - Adult, 3,500, and Children's, 400.
Anticipated levels of circulation, Le. proportion of collection checked out at any given time which
has a direct affect on the amount of shelving required:

Attention: Mr. Brad Miller

Subject: Existing Facilities Analysis to identify CostsRequirements for Reuse of the Existing
Facility
Gentlemen:
In acciordance with the terms of our agreement, Blaylock Engineering Group has completed an
updated structural assessment of the subject facility. This work was performed by Messrs.
Matthew N. Martinez, S.E. and Gary W. Tubach, S.E. and included a visit to the site on May
1 1 , 19%. Our analysis of the existing facility structural deficiencies and written description of
the structural system requirements for the building renovation are as follows: e
Our cursory rcwiew of the existing structural drawings for the library building and a on site
inspection find s the following structural deficiencies with respect to the 1994 Uniform Building
Item No. 1 - Current Code Seismic Force Level Requirements: The current '94 UBC requires
masonry bearing/shear wall structures to be designed for seismic forces that are 38% higher than
the force levels required in the 1966 Uniform Building Code (in effect when the building was
Item No. 2 - Inadequate Lateral Force Resisting System at the Old Adult Reading Room Rool
(between grid lines A & B) and at the Clerestory Roof (between grid lines B & C): The
predominant vertical lateral force resisting system for these roofs appears to be cantilever steel
columns or an inverted pendulum-type structural system. Because of little redundancy and
smaller inherent ductility of this type of system the current Uniform Building Code requires this

type olf structure to be designed for twice the lateral seismic load of the shear wall structure
existing at the rest of the structure. Our analysis indicates that current code lateral force levels
greatly exceed the capacity of this cantilever column system at these two roofs.
Item No. 3 -Diaphragm Discontinuity Irregularity and Inadequate Diaphragm Connections
(shear transfer mechanism) at the North Mezzanine Floor: The stair and elevator openings at the
north inezzaniiie floor between grid lines B & C result in a diaphragm discontinuity irregularity
(plan structural irregularity type 3 per ’94 UBC Table 16-M) and renders the diaphragm
inadequate to Iransfer the floor seismic loads to the shear wall at grid line 3. Elements of this
diaphragm woiild be required to be designed for forces 84% higher than design requirements that
were in effect when the building was constructed. It appears that the concrete block walls
enclosing the adjacent toilet rooms and heating equipment room and the west concrete block wall
of the adjacent record storage room are necessary to provide the lateral resistance for mezzanine
floor north-sou th seismic loads. Lack of seismic collector beams and drag connections however,
from tihe floor (diaphragm to these north-south shear walls, results in a load path through the short
east-west concrete block cripple walls between the mezzanine floor and the offset floor slabs at
the heating eqiipment and the mechanical rooms. Concrete block walls have a much smaller
capacity to resst seismic loads that are normal to the walls and loading the walls in this fashion
results in an undesirable cantilever column or inverted pendulum lateral load resisting system
similu to the mofs of item No. 2 above.
Item No. 4 - Adequacy of the Concrete Block Shear Walls and Diaphragm Drag Connections:
The horizontal reinforcing at the concrete block walls does not satisfy the minimum horizontal
reinforcing required by current codes for walls that resist seismic loads. The shear capacities of
the concrete block shear walls and the diaphragm drag connection capacities at the walls are
most likely significantly below current code lateral force levels at many locations. Lack of
special inspection for the concrete block walls (as was provided for the formed concrete floors
and columns) results in allowable stress levels of one half allowable levels for masonry walls
constnicted wii:h special inspection to guaranty that construction procedures are used that ensure
the structural iitegrity of the walls. Also the partially grouted concrete block shear walls (only
the cells of the hollow core units with reinforcing are grouted) have less shear capacity than solid
grouted concrete block shear walls.
Item No. 5 - F’alling Hazards from Non-Structural Elements: The 4-foot wide by 20-foot high
screeas elements between grid lines D and E.2 on the east and west sides of the building are
composed of open decorative masonry units sandwiched by steel channel sections. This
construction appears to be within code parameters for unreinforced masonry. However,
horizointal bracing in the plane of the outrigger beams at the head of these panels to stabilize for
in plane seismic loads would reduce the potential for cracking at the masonry units and

dislodging of the masonry units from the steel frames in a major earthquake. During the site visit
corrosjon at the bottom of the steel channels from landscaping water sprinklers was noted. The
rust should be cleaned off these steel sections (preferably by sand blasting) and the steel sections
repainted with a protective coating to prevent further deterioration of the steel sections. Bracing
of bookshelves, also considered to be a falling hazard in an earthquake, was observed at some
Item No. 6 - Other Observations: An exterior exit stairs on the west side of the structure
appeared to be adequately tied to the structure, however some of the light guard rail posts were
observed to be completely rusted through. This stair guardrail should be repaired or replaced as
soon as possibie. Also a minute mount of spalling and cracking of the thin concrete 2nd floor
overhangs was observed. Similar thin ledges occur at the slab on grade outside the glass walls.
If these thin slab ledges at the slab on grade are not removed in the new construction the architect
should consider concrete repair at these locations.
Foundations and Concrete Block BearingBhear Walls and Cost Implications
Vertical Gravity Force Resisting Systems
Floor !System: Alternative A adds approximately 6570 square feet of second floor area to the
existing 7830 square foot second floors. In order to increase the potential for utilizing the
existing foundations and minimize the increase of the building mass and seismic loads, a light
floor system consisting of metal deck with a light-weight structural concrete (1 10 pcf) topping
supported composite steel beams is recommended. Because the increased second floor plan area
would increase the gravity foundation loads to all the footings except those at grid lines D.5 and
E, new first story column grid lines are proposed midway between grid lines A, By C and D
resulting in a 20' x 25' column grid at the first level. These steel columns with isolated spread
column footings need only extend to the second floor leaving the 40' x 25' column grid at the
second floor level and above.
Roof System: As with the floor a system, a roof system that minimizes the dead load added to
the existing foundations and building seismic mass is recommended. Steel deck with insulating
concrete fill (;!2 pcf) and rigid insulation board, similar to that used on the new Carlsbad City
Library, supported on steel beams is recommended. Roof slopes should be achieved by sloping
of the steel framing in lieu of varying the insulating concrete thickness to minimize the roof dead
load.

Letter to Mr. Ekad Miller
Existing Concrete Block Bearing Walls
In order to salvage the existing concrete block walls with insufficient horizontal reinforcing, (see
Item No. 4 above), it will be necessary to add steel or concrete columns and floor and roof beams
immediately adjacent to the walls to create a complete vertical load resisting space frame. These
added columns and beams would be on the column grid pattern described above at locations
where the existing concrete block walls support the floor and roof framing. It should be noted
that the engineering and construction costs required might negate the savings gained from
salvaging these concrete block walls.
e
The proposed Full rigid second floor diaphragm precludes the use of a mixed vertical lateral load
resistiing system as was possible €or the split flexible roof diaphragms of the existing structure.
Concrete block shear walls are an economical cost effective lateral force resisting system in
buildings where flexibility for fkture remodeling is not required. Approximately 200 linear feet
of new concrete block shear walls would have to be added in both the north-south and east-west
directions (400 linear feet total) to reduce the force levels in the existing partially grouted,
uninspected cclncrete block walls to code acceptable levels. A predominant portion of the new
east-west shea- walls needs to be added at grid line A in place of the existing cantilever column
system to avoid a torsional irregularity (plan structural irregularity type 1 per '94 UBC Table 16-
M). It should be noted that the amount of new shear wall required to achieve the stiffness
necessary to limit loads on the existing partially grouted, uninspected concrete block walls is no
less than would be required for a new structure. In other words, the cost for these new concrete
block wall would be similar to that required if all the existing concrete block walls were
demolished. Consequently there is no cost savings in the lateral force system by salvaging the
existing concrc te block walls. e
The superstructure systems proposed maximize the potential for utilizing the existing
foundations. New spread column footings would have to be added at the new first story columns
proposed to keep from overloading the existing foundations from the new second floor areas.
New continuous wall footings would have to be added at new shear walls. The existing shear
wall footings could be used as footings for new shear walls at demolished walls by leaving the
footing dowel reinforcing in place and/or drilling and epoxy grouting new dowels in place.
Enlarging the ends of existing wall footings (dumbbell footings) may be required if used to resist
larger overturning loads from higher seismic force levels. It appears that using the existing
foundations may save between 33% to 50% the cost of foundations for a new structure. If the

founditions arid utilities. It may also be desirable to completely remove the slab paving at the
interior patio between grid lines C & C.2 and grid lines 2 & 3 and pour a new slab over a
waterproof membrane and sand base to ensure new interior floor finishes are not damaged by
water infiltration from the soil.
Summary - Alternate A
The structural systems proposed above are similar to those used in the new Carlsbad City Libra9
with the exception of use of lightweight structural concrete fill at the second floors in lieu ol
normal weigh1 concrete. Because costs associated with the complications of salvaging the
existing non-code-complying partially grouted concrete block walls are likely to exceed the costs
of demolition we recommend that they be demolished and new solid grouted reinforced concrete
block walls be built at locations that optimize space planning in the new facility. We believe that
the square footage structural costs for Alternate A construction will be similar to the new
Carlshad City Library square footage costs with a 33% to 50% savings in the foundation costs
and some poss tble savings in new slab on grade construction.

Alternate B - Structural Systems
The structural :systems recommended for Alternate B are identical to those for Alternate A above
and those used on the new Carlsbad City Library except that normal weight concrete fill may be
used ai the second floor over the new building foot print outside of the renovated area. It is
presunned that the soil conditions at the new building foot print are similar to those at the existing
building so that shallow spread footings could be used. Structural square footage costs should be
assumed to be similar to those for the new Carlsbad City Library with a 33% to 50% savings on
the foundation costs at the renovated portion.
Alternate C - Structural Systems
The structural systems recommended for Alternate C superstructure are identical to those for
alternade A above and those used on the new Carlsbad City Library except that normal weight
concrete fill bz used at the second floor throughout. Shallow spread footings are the most
economical cost effective foundation system providing that soil conditions at the site are suitable
for their use. Less suitable foundation soils at the specific site may require more expensive
deeper foundat ions.

The Library is served by four multizone air handling units, with integral humidifiers, serving twelve
separate zones. A sixty-six ton water cooled chiller provides chilled water to the air handlers for
space cooling. A cooling tower, located on grade at the south end of the building, provides
condenser water for the chiller, and a boiler provides 180 degrees Fahrenheit water to the air
handlers for space heating. Each zone is controlled by its own thermostat and humidistat. The
control system is pneumatic. A four-pipe fan coil serves the addition at the northwest corner of the
building.
Most of the system was installed during construction of the original building in the mid 60’s. The
air handlers, chiller, boiler, pumps and controls were from observation in satisfactory condition and
operating adequately. The cooling tower, condenser water piping and pump were replaced in 1989
and are in good condition. Each component of the system was observed for vibration and seemed
to be operating within acceptable ranges. The equipment transmitted noise and vibration were
reasonably attenuated by the vibration isolators and enclosure shielding. As a result, noise in the
occupied spaces was barely discernible. Chiller operation was obvious in the rest rooms, but was
not at an objectionable level. Minor amounts of noise from the air handlers were more than
masked by air noise from the air diffusers. Each of the twelve zones was observed for comfort
level. All were Found to be maintaining the temperature settings set at the thermostats. It should
be noted that outdoor conditions were moderate on the days the system operation was observed.

The design air (quantity for the administrative area is currently 4,700 cfm. This should be adequate,
and perhaps even excessive, for a reading area or book stack area.
The system has, thus far, been well maintained and can be expected, with proper maintenance,
to last indefinitely with only replacement of failed equipment. The bearings for air handler #3,
however, were observed to be in marginal conditions and should be scheduled for replacement.
Air quantities actually delivered to the conditioned spaces should be measured to determine air
handler perforrnance and general system balancing.
Additionally, the supply and return ducts should be cleaned as well as the heating and cooling coils
within the air handlers and fan coil unit. The thermostats should be calibrated on an annual basis
to increase comfort levels and system efficiency. On the long term, motors at the air handlers and
pumps should be replaced with high efficiency units. SDG&E has an incentive program in place
which will provide funds for the use of high efficiency motors, boilers and chillers. Representatives
of their “Energy Conservation Program” should be contacted when these items require

The preceding mostly represents a copy of the report given in 1990. Today, the concern is that
most all of the air conditioning equipment and distribution systems have exceeded their useful life
by recognized standards such as ASHRAE. Most of the installation has been serving the building
for over 30 years. Discussions with several of the long time employees have disclosed certain
unstable conditions in various areas of the library. Most significant is the variation of space
temperatures and air distribution withing the administrative areas. Indications are that some
space:; are too hot or cold while others are the opposite. The air distribution zoning and location of the room thermostat could be one of the causes. Another explanation is that the system may
not have been balanced for some time. This along with the age of the system, can cause
decreased sysiem capacity. It should also be noted that age will also take its toll on the value of
the duct insulalion. With age, the ability of insulation to keep out unwanted heat or cold can have
an adverse effect on the supply air temperature. Consequently, the air distributed to the space
may be higher than designed. This leads to a longer period to heat or cool a room. The ultimate
result is that the cost of energy to provide the correct space condition will go up. The system is no
longer performing at its peak efficiency. In terms of efficiency, the existing air conditioning system
0 * e 0 e is outdated. e e e 0
0
If the existing building were to remain, it is recommended that the entire system be replaced. Once
the existing building is made more energy efficient, retaining the existing cooling tower for the same
floor airea is a real possibility. Of course, this would depend on how extensive the remodeling
increases the room volume. If an addition to the building is provided, it is the recommendation of
this report to r13move the existing air conditioning system in its entirety and be replaced by a
completely nevi system to serve the entire building as one. Consideration can be given to the
existing cooling tower as a back up or a supplement to the new system.

0 BUILDING RENOVATION
e Regardless of the alternatives listed below, it is the recommendation of this report that all new air
conditioning equipment should be used. In alternate A, the existing cooling tower may last another
IO years. The understanding here is that consideration should be given for the long term condition.
That is, useful life of the proposed installation should last from 20-30 years with proper
maintenance. Each alternative wiill incorporate two separate pumps for the chilled water and
heating hot water systems. The folRowing are the various alternatives to consider:
-- Alternate A Modifications to the existing structure to meet today's California Energy Act will
assure installation of an air-conditioning system which will match the present capacities (66 tons).
The recommendation is to change the cooling plant to an air cooled system which would eliminate
the need for two separate pieces of equipment - chiller and cooling tower. Maintenance, in turn,
would be simplified. In addition, the building air distribution system would include four separate
air handlers to serve the administration, core area, stack and reading area, and the second floor
geneology area A variable air volume system would be utilize along with variable frequency drives
for the air handlers. This would save on energy by automatically compensating for the low as well
as the peak periods of the library's occupancy. The heating system would be replaced by a 1.35
mbh input boiler and distribution piping.

e
The Library is served by a standard building system for potable water supply, irrigation, sanitary
drain and venting. The 2" domestic potable water supply is currently supplying 107 g.p.m. through
154 fixture unit!; (fu). The 4" drain, waste and vent (DWV) system has an available capacity of 216
fu and is handling only 94 fu. Natural gas for the space heating boiler is supplied through a
metered 2-1/2" low pressure line with an available capacity of 1,600 cfm which is presently using
1,350 ccfm. Domestic hot water is supplied by three small electric storage type water heaters. All
parts of this system appear to be in satisfactory condition with no need, barring failure, to replace
any of the fixtures or equipment.
An updated report indicates that the restroom has been brought up to current ADA requirements.
There is no indication that the plumbing system is failing or has required frequent servicing. When
the domestic hot water heater needs replacement, consideration should be given to converting the
electric: heater YO a gas fired unit. This will require bringing in combustion air, but the economics
will pay for the conversion in a relatively short time as a result of the energy savings realized.
In the event that the building is extended to the east, the existing underground services including
gas and water, will be required to be rerouted and/or resized depending on the addition of any new
loads. Caution will be required where the existing sewer line runs close to and parallel with the
east side of the building. The new construction work will require extra care in digging new footings
in the area around or over the pipe. It is very conceivable that the whole service main outside the
building may require replacement. This is something that will not be known until the sewer line is
uncovered.

Serious consideration should be given to providing a sprinkled building for the purpose of life
safety. This is especially true if the building extension is provided. In addition to the sprinklers, a
new fire alarm control panel would be required to meet current codes. An alternative dry type
systeni may be considered for those archive areas containing rare books. a 0

1.01 ELECTRICAL SERVICE
A. Analysis:
I. The existing building service is taken from SDG&E (12KV) overhead
service pole #218108. The electrical service to the building is 1000
amps, 208/120 volts, 3 phase, 4 wire, and is provided via a 15OKVA
SDG&E padmounted transformer. The existing service feeder
consists of ,three (3) 4zC.-4#500MCM (each conduit) for a service
feeder capacity of 1140 amps.
B. Conclusion:
1. The electrical service feeder is adequate for the existing building
loads, but is not adequate to support any future building expansion or
modifications. Also, the existing SDG&E transformer KVA capacity
appears to tie undersized for the building service. a

water pipes, a telephone backboard, a data backboard and a fire
alarm control panel in this room.
1. The existing main switchboard is adequate to support the existing
building loads. However, based on the limited amount of additional
capacity in the board, the lack of available spare parts, and the age
of the equipment, the existing main switchboard is not suitable to
support any future building expansion.
The existing main electrical room will require work to relocate the
telephone and data backboards, fire alarm panel and cold water
piping in the space to another area of the building.
2.
1.03 PANELBOARDS e
A. Analysis:
1. The existing branch circuit breaker panels are in fair condition.
However, the panels were manufactured by the same company as the
main switchboard. Since this company is no longer in business,
repair parts will be difficult or impossible to get. All existing
panelboard:; are full in relation to the available breaker space on their
bus.
B. Conclusion:

1. The existing panelboards are adequate to support the existing building
loads. However, the existing panelboards are not suitable for future
building expansion or renovations.

1.04 INTERIOR LIGHTING
A. Analysis:
1. Surface mounted fluorescent lighting fixtures are used throughout the
entire building. Multi-level switching is utilized in large open areas,
although the smaller rooms and private offices are not equipped with
dual level switching as required by present California Energy Code
Title 24 requirements. ADay Lighk lighting controls have not been
utilized in areas adjacent to large windows. In some areas, light
meter readings exceeded 300 footcandles. Footcandle readings were
taken in all areas and the average maintained level falls between 90
and 150 footcandles. Due to the quantity of light fixtures used,
however, most areas are operating at approximately 5 watts per

1. The current Title 24 lighting (energy) allowance for this building is 1.5
watts per square foot. To reach this goal, the existing building lighting
system will require a complete redesign with an emphasis on fixture
type, application and location. Also, Title 24 energy conservation
methods such as daylig hting, occupancy sensors, multi-level
switching and timeclock control must be utilized to aid in reducing
energy consumption in the building.
1.05 EXTERIOR LIGHTING
1. The existing exterior lighting consists of both fluorescent and high
intensity discharge (HID) fixtures. Fluorescent fixtures are wall and
ceiling mouiited at entryways and exits. HID fixtures are installed at
the loading dock, entry ways and building perimeter for landscaping
and wall washing.
All areaway and parking lot lighting fixtures have HID (mercury vapor)
lamps. Additionally, the lighting at the extended parking lot has
newer, contemporary Ashoe-box= light fixtures installed adjacent to
the original light fixtures. Under the contemporary fixtures there is
1Ofc at ground level, but there is only 1.3fc at ground level for the
original fixtures. Clearly the two fixtures have different photometric
characteristics, making even distribution of light difficult. Parking lot
fixtures are 12 feet high and 100 feet apart. Insufficient lamp wattage,
mounting height and distance between fixtures make it impossible to
meet the Illuminating Engineers Society's required maintained
average illurmination level of 0.5 footcandles.
2.
B. Conclusion:
1. The existing exterior lighting should be removed and replaced with
new energy efficient luminaires. Building and landscape lighting
should be compact fluorescent and/or metal halide. Parking lot
fixtures should be metal halide luminaires mounted on 20'-0z poles.
All exterior lighting should be controlled via photocell and timeclock.

APPENDIX 5: COST ANALYSIS DOCUMENTATION a
The attached summary pages represent the work of Construction Analysts, lnc.,
cost consultants for the feasibility study. The following revisions were made to
these documents to derive the figures shown in the table included in the body of 0 e the report:
e e a e
e
0 The cost estimates for Alternative B and C attached reflect a preliminary
program area of 48,900 gross square feet and parking for 245 cars. The
totals were reduced to reflect the 45,155 square foot and 226 cars in the
final program. Costs were reduced on the basis of the square foot costs.
The cost estimates for Alternative B and C attached are inclusive of the Off-
Site Costs whereas Alternative A is not. Those costs have been pulled out
as a separate line litem in each alternative in the body of the report to create
a consistent basis for comparison.
The budget for Library Furnishings and Equipment was increased to $48/SF
at the recommendation of the consulting librarian to reflect recent current
experience and to include such as items as computer network cabling.
Several Project Costs percentages were adjusted to reflect the project
management experience of City of Carlsbad staff with the Carlsbad City
Library and other rlecent projects.

Interim Estimates
Neither SANDAG nor the City has officially adopted estimates of individual-year
building activi?y or popuiatiori growth MOE recent than the SANDAG Series 7. Forecasts (based upon 1985 assurnpuons). The Series 8 Forecast (1990
assumptions) for local jurisdictions wem not adopted by SANDAG or any local agency, although 'interim" numbers were published. The current 2020 Forecast
effort (formeriy known as Seiies 9) is not yet completed.
The Pl,anning department has provided the Finance Department with a one-year
forcccast of growth for the 19498-1 999 fisca1 year. If interim forecasts of population beyond one year are needed, the Planning Department could
produce such forecasts only with difficulty.
