needs in light of the future, constructability, reliability and maintainability. In
addition, we mitigate, to the best of our ability, unforeseen expenses and to
avoid unnecessary costs by installing preventive measures. Our cost control
approach has seven significant ingredients:
Defining an accurate scope of work.
0 Conducting thorough field surveys to record as-built conditions.
Preparing detailed cost estimates at each phase of the project.
Performing design reviews to assure compliance with scope of work and
budget.
Frequently reviewing progress with clients.
Preparing a complete set of construction documents.
D Open dialog with contractor and weekly review of construction progress.
Management Under strict direction of a project manager, all tasks are to be delegated and
progress is checked on a daily basis. The project manager is the Point-Of-
Contact for answers to all questions, comments and concerns any of the
parties involved may have. If a task can not be completed in-house, the best
talent available will be provided to meet the needs of the project.
Cost Estimating Estimation of probable costs is an essential element of a project and a quality
measure of our design work. Our estimates incorporate our experience with
past and current projects. We track bid costs, change order costs, and obtain
estimating figures directly from contractors as well as from current cost books
such as "Means". In some instances, we may use local square foot cost
averages and also obtain equipment quotes and do quantity surveys for a
more complex project.
Codes & Standards DTA abides by all local, state and national regulations. Each of our California
public sector projects observes California State Codes & Regulations (CCR)
Titles 8, 19, and 24. Moreover, we have performed plan checks for the Los
Angeles Unified School District, and we plan to continue serving a variety of
school districts through ongoing projects.
Quality Assurance Phase review meetings are scheduled with clients at the commencement of
every project to coordinate requirements and design. However, we encourage
additional coordination meetings between phases and communication on an
as-needed basis so that the design and cost are agree upon by all parties
involved. Plans and specifications are reviewed by the project manager and
principal in charge prior to submitting for plan check.

The existing central plant installed in the mid 1980s and has deteriorated donsiderably and it could not
meet cooling and heating requirements of the building. Dahl, Taylor and AssOciates evaluated the
existing HVAC system and recommended to The County of San Diego to replace and upgrade their
central plant to a 125-ton capacity for the water source heat pumps. The central plant equipment was
upgraded and included the replacement of the cooling tower, water pumps and boiler. A new digital
control system was installed to monitor and control the central plant and the 50 water source heat pumps.
The County of San Diego also requested Dahl, Taylor and Associates to ealuate and assess the indoor
air quality of the building. The occupants of the building have reported uncomfortable indoor
environmental conditions that may be contributing to an employee's "eyes bum, lungs bum, and hands
,going numb." DTA performed an indoor air quality survey to determine what factors, if any, caused the
employee's experience. The building was surveyed for mold and bacteria and for CO2 levels. It was
determined that the fresh air ventilation for the entire building were inadequate and did not meet the
,ASHRAE 62-2001 Indoor Air Quality Standards
Dahl, Taylor and Associates calculated and determined the required ventilation for the building. New on
Demand Ventilation units were designed and installed to meet and improve the indoor air quality. The
new ventilation units are controlled by the Johnson Controls system to ensure proper and efficient fresh
air ventilation is delivered.

Dahl, Taylor & Associates, Inc. performed structural evaluation and analysis of concrete slab, strength
deflection, and seismic analysis to determine if the existing slab can still be used. A sub-contractor is
hired to collect data on existing structure such as performing survey and doing "X-Ray" on rebars cylinder
test for concrete strength. The X-Ray data is difficult to collect due to hard ceiling areas which are not
easily accessible. Finally, we decided to pick up two samples at each bay and each direction to solve the
problem and to present the typical design.
Project is completed successfully and client is satisfied with our professionalism in keeping the client
informed at all time during the project as well as with the results of the analysis.

The Emergency Communication Complex (ECC)isownd and operated by the Deparméñt of General
Service of the County of San Diego The ECC was designed and built as an essential facility to withstand
a large seismic event and to provide uninterrupted communication services to the various emergency
operation centers and to the County of San Diego Shenffs Department The ECC is a mixed use facility
which includes the 911 Dispatch Center; dispatchers' training classrooms, emergency operations center,
computer rooms offices and an exercise room The building has been built on base isolation foundation
The HVAC system serving the second floor dispatch center and training classrooms has not been
effective in controlling and maintaining the room temperatures The HVAC system serving this area is part
of the computer room unit (CRUs) air coIditioning system The CRUs systems are not capable of
providing the design "airflows to these areas As result, the design room temperatures can not be
maintained even though the CRUs have the capacity to meet the cooling loads
Dahl, Taylor & Associates (DTA) along with a mechanical contractor provided the design modifications for
the HVAC system and the equipment platform on the roof. DTA provided the structural engineering and
design for the platform on the roof. The equipment platform and roof penetrations were designed to
minimize the impact to the dispatch call center operations during construction A 20-ton package air
conditioning system was designed to replace the air distribution from the CRUs on the first floor.,The new
package unit will provide the pririiary cooling of the dispatch center and training rooms. The modifications
to the CRUs was designed to provide backup cooling, if the package unit is being serviced or repaired

The San Diego Unified Port District has an Agreement with the Marine Corps Recruit Depot (MCRD)
I Base in San Diego, CA for the exchange of certain real property and for construction of facilities. The
Port District is proposing to widen a taxiway adjacent to Runway 9 at San Diego International Airport
(Lindbergh Field). The proposed expansion area is currently owned and operated by MCRD. Under the
I
Agreement, the Port District will provide and perform upgrades and improvements to various buildings
and roads along with the construction of several new buildings in exchange for the land in the expansion
area.
I The relocation and improvements of various training areas will require modification to the existing
steam distribution system. Dahl, Taylor & Associates have been requested to provide an assessment
and recommendation to the proposed modifications to the steam trap stations and the steam and
I
condensate lines in the proposed runway area. The stream trap stations are currently installed above
grade every several hundred feet along the piping distribution. The current above grade installation will
interfere with the requirements of the new proposed training area. The Port District would like to
evaluate the available options (3 options being assessed) for modifying the trap stations for below
I grade installation or for relocation. The Port District has also requested that Dahl, Taylor & Associates
evaluate the rerouting options for modifying the steam and condensate lines in the new runway area,
between Russell Avenue and Henderson Avenue, adjacent to Guantanomo Street.

The purpose of this study was to evaluat&ât least three options for replacing and upgrading the DC power
plant at Magnetic Silencing Facility. Thethreè options included diesel generators, natural gas generators
and DC power supplies. All options were to meet the new power loads of 8.3 MWfor.thè deperming
operation at the Point Loma Naval Sübmrine Base. Conceptual designs were developed to evaluate the
cost and construction requirements of each option. The options were also evaluated for its compliance
with the curent and near future environmental regulations. 'A life cycle cost analysis was also performed to
determine the overall cost of installation and maintenance of each option.
The results of the study and evaluation show that Option 3, the PC Power Supply option, is the best option
for the upgrade of the DC power plant The DC Power Supply option provides the best option in terms of
total installed cost,, operating cost and environmental compliance. The estimated construction cost for
Option 3'was appróximàtely $6.6 million versus $17.7 million and $21.5 million for Option I and Option 2
respectively. • . . -
Also evaluated was thé'addition of Ship to Shore power and communications services. Location of a
Stainless Steel-enclosed Substation on the Pier is the best option. The installed cost is lower, and a
stainless steel enclosure will be more resitant to corrosion.
