The Plans for the work show conditions as they are supposed
or believed by the Engineer to exist; but it is not intended
or to be inferred that the conditions as shown thereon
constitute a representation by the District or its officers
that such conditions are actually existent. The District,
any of its officers, and the Engineer shall not be liable
for any loss sustained by the Contractor as a result of any
variance of the conditions as shown on the Plans and the
actual conditions revealed during the progress of the work.
(c) Conformity with Plans and Allowable Deviations: Finished
.surfaces in all cases shall conform with the lines, elevations,
grades, cross sections, and dimensions shown on the Plans, or
if no specific elevations are shown on the Plans, the elevations
and grades furnished by the District's Representative shallgovern.
(d) Coordination of Plans and Specifications: The Plans,
Specifications, and all supplementary documents are essential
parts of the Contract and a requirement occurring in one is
as binding as though occurring in all. They are intended to
be cooperative and to describe and provide for a complete work.
In the event of an apparent difference between Plans and
Specifications, reference shall be made to the District's
Representative, whose decision thereon shall be final.
(e) Interpretation of Plans and Specifications: Should it
appear that the work to be done or any of the matters relative
thereto are not sufficiently detailed or explained in the

to the District's Representative for such further explanations
as may be necessary and shall conform to them as part of the
Contract, so far as may be consistent with the original
Specifications; and in the event of any doubt or question
arising respecting the true meaning of the Specifications,
reference shall be made to the District's Representative,
whose decision thereon shall be final.
In the event of any discrepancy between any drawing and the
figures written thereon, the figures shall be taken as correct.

to the District's Representative so that proper inspection
may be provided.
The inspection of the work shall not relieve the Contractor
of any of his obligations to fulfill the Contract as prescribed.
Defective work shall be made good, and unsuitable materials
may be rejected notwithstanding the fact that such defective
work and unsuitable materials have been previously overlooked
by the District's Representative and accepted or estimated
for payment.
Any defective material or workmanship, or any unfaithful or
imperfect work which may be discovered before the final
acceptance of the work shall be corrected immediately on
the request of the Engineer, or if such should be
discovered within one year after the final acceotance, it
shall be corrected immediately on demand of the District.

District's Representative to suspend the work wholly or in
part. The work shall be resumed when methods or defective
work are corrected as ordered or approved in writing by the
District's Representative.
•In the event that a suspension of work is ordered as provided
above, such suspension of work shall not relieve the Contractor
of his responsibility to complete the work within the time
limit specified, and shall not be considered cause for
extension of the time for completion, and further, such
suspension of work shall not entitle the Contractor to any
additional compensation.
-(j) Errors or Discrepancies Noted by Contractor: If the
Contractor, either before commencing work or in the course of
the work, finds any discrepancy between the Specifications and
the drawings, or between either of them and the physical
Conditions at the site of the work, or finds any error or
omission in any of the drawings or in any survey, he shall
^promptly notify the District's Representative in writing
"of :such discrepancy, error or omission. If the Contractor
-observes that any drawings or Specifications are at variance
"with any applicable law, ordinance, regulation, order or
decree, he shall promptly notify the District's Representative:in writing of such conflict.
-The District's Representative, on receipt of any such notice,
-shall, promptly investigate the circumstances and give
appropriate instructions to the Contractor. Until such

either directly or indirectly after his discovery of such
error, discrepancy or conflict, will be at his own risk
and he shall bear all costs rising therefrom.

All drawings must be marked with the name of the project and the
name of the Contractor and be numbered consecutively. All draw-
ings must be complete in every respect.
The Contractor shall make such corrections as shall be
required by the Engineer and receive the Engineer's stamp of
approval before commencing the work involved. If the shop
drawings show variations from the Contract requirements
because of standard shop practices or other reasons, the
Contractor shall make specific mention of such variations in
his letter of transmittal in order that.(if acceptable)
suitable action may be taken for proper adjustment of the
Contract; otherwise, the Contractor will not be relieved
of the responsibility for executing the work in accordance
with the Contract, even though the shop drawings have been
approved. Approval of shop drawings will be general and
shall not relieve the Contractor from the responsibility for
proper fitting and construction of the work, nor from fur-
nishing the material and work required by the Contract
which may not be indicated in the shop drawings when approved;
neither does it relieve him from responsibility for errors
in shop drawings.

liens, encumbrances, or charges, and further agrees that
neither he nor any person, firm or corporation furnishing any
material or labor for any work covered by the Contract shall
have any right to a lien upon the premises or any improvement

the Contractor from installing metering devices or other equipment
of utility companies or of municipalities, the title of
which is commonly retained by the utility company or the
municipality. Nothing contained in this article, however, shall
defeat or impair the right of such persons furnishing materials

fails to prosecute the work or any separable part thereof
with such diligence as will insure its completion within the
time specified herein, or any extension thereof, or fails
to complete such work within such time, or the Contractor
should be adjudged a bankrupt, or if he should make a general
assignment for the benefit of his creditors, or if a
receiver should be appointed on account of his insolvency,
or if he or any of his subcontractors should violate any of
the provisions of this Contract, the District may serve
written notice upon the Contractor and his surety of its
intention to terminate this Contract, said notice to contain
the reasons for such intention to terminate this Contract;

notice such violations shall cease and satisfactory arrange-
ments for the corrections thereof be made, this Contract
shall, upon the expiration of said ten (10) days, cease and
terminate.
In the event of any such termination, the District shall
immediately serve written notice thereof upon the surety
and the Contractor, and the surety shall have the right to
take over and perform the contract; provided however, that
if the surety within fifteen (15) days after the serving upon
it of a notice of termination does not give the District
written notice of its intention to take over and perform the
Contract, the District may take over the work and prosecute
the same to completion by contract or by any other method
it may deem advisable for the account and at the expense of
the Contractor, and his surety shall be liable to the
District for any excess cost or other damage occasioned the
District thereby; and in such event the District may,
without liability for so doing, take possession of and utilize
in completing the work such materials, appliances, plants and
other property belonging to the Contractor that may be on
the site of the work and be necessary therefor.
The foregoing provisions are in addition to and not in
limitation of any other rights or remedies available to the
District.

thereof.
SECTION VI - PROSECUTION AND PROGRESS
(a) Subcontracting: Specialty subcontractors shall be
utilized for the performance of such part of the work under
this Contract as under normal contract practices are
performed by specialty subcontractors, unless the District

determines that the performance of specialty work by
specialty contractors will result in increased cost or
inordinate delays, provided however, that the Contractor
shall not subcontract any work to be performed or any materials
to be furnished in the performance of this Contract without
the prior written consent of the District. If the Contractor
shall subcontract any part of this Contract, the Contractor
shall be as fully responsible to the District for the acts
and omissions of his subcontractor and of the persons either
directly or indirectly employed by his subcontractor as he
is for the acts and omissions of persons directly employed
by himself. Nothing contained in the contract documents
shall create any contractural relationship between any
subcontractor and the District. The Contractor shall bind

to be bound by the terms of the contract documents as applicable
to his work, unless specifically noted to the contrary
in the subcontract in question, approved in writing as
satisfactory to the District.

subject to a prior lien for services rendered or materials
supplied for performance of the work called for under said
Contract in favor of all persons, firms or corporations
rendering such services or supplying such materials.

written consent of the District's Representative.
(e) Temporary Suspension of Work: The District's Represen-
tative shall have the authority to suspend the work wholly or
in part for such time as he may deem necessary due to the

Contractor shall immediately comply with the written order
of the District's Representative to suspend the work wholly
or in part. The work shall be resumed when methods or

tenth
Payments: The District shall on or before the
(10th) day of each calendar month after actual construction
work is started, except in case of final estimate hereinafter
provided, cause an estimate in writing to be made by the
District's Representative of the total amount of the work
done and materials furnished by the Contractor and incorporated
into the work to the first (1st) day of the month in which
the estimate is made. In estimating such value, the District's
Representative may take into consideration, along with other
facts and conditions deemed by him to be proper, the ratio
of the difficulty of the work done to the probable difficulties
of the work to be done. The District shall retain ten percent
(10%) of such estimated value as part security for the ful-
fillment of the Contract by the Contractor, and shall within
fifteen (15) days after the preparation of such estimate
pay to the Contractor the balance of such estimated value
after deducting therefrom all previous payments and all
sums to be kept or retained under the terms of the Contract.
(b) Final
after"
Payment: The District's Representative shall,
the satisfactory completion of the work, make a final
estimate of the amount of work done thereunder and the value
of said work, and the District shall pay the entire sum so
found to be due after deducting therefrom all previous
payments and all amounts to be retained under the provisions
of the Contract. All prior partial estimates and payments
shall be subject to correction in the final estimate
and payment. The final payment shall not be due and payable

pressure the pipe shall be sharply struck at six inch intervals along
the weld with a 1-1/2 pound hammer, with blows equivalent to drooping
the hammer a distance of one foot for No. 14 gauge Dine, increased
by an increment of six inches for each increase in thickness by one
gauge number. The blows shall be struck in such a manner as to thor^
oughly jar the weld. Immediately after the hammer test has been
completed the pressure shall be maintained a sufficient length of time
to allow, for the inspection of the section for tightness. All leaks
shall be repaired by chipping to sound metal, hand welding, and the
section then re-tested. All tests shall be made against a fabricated

coating shall be a bright basic wire of low carbon, open hearth
steel, not annealed after the last draw, and with a minimum ultimate
tensile strength of 80,000 p.s.i., and conforming to A.S.T.M. Speci-
fication A-82 - "Cold Drawn Steel Wire for Concrete Reinforcement."
B-6.2. Interior Lining - The cement mortar shall be applied
to the inside of each section of pipe by means of troughs or retract-
ing feed lines while the pipe is rotated with its axis in a horizontal
position . This initial application shall produce a uniform longi-
tudinal distribution throughout the length of pipe. Then the pipe
shall be rotated at a speed which will uniformly distribute the
mortar around the inside circumference of the pipe and produce a
dense, smooth and uniformly compacted lining. During the spinning
operation, surplus water, which has been forced to the surface
of the lining, shall be removed by a blower or other suitable means.
Immediately after the spinning operation, each section of pioe shall
be tilted to drain off any excess water still remaining, and each
end shall be capped with a waterproof cover, properly attached, to
prevent the escape of moisture from the interior of the pipe. The
pipe shall be carefully moved to a storage area and cured under
sprinklers without being disturbed for not less than 4 days if an
exterior cement mortar coating is to be applied, for not less than
7 days if the exterior coating is ommited.
B-6.3 Exterior Coating - The cement mortar shall be applied
to the outside of each section of pipe by means of a nozzle, or
nozzles, through which the mortar is forcibly expelled against the
outside surface of the pipe in such a manner as to form an even,
dense and tightly adhering coating. During the coating operation,
the pipe shall be rotated and moved in a longitudinal direction be-
neath the coating nozzles. The rotation and longitudinal travel of
the.pipe shall be uniform and at the proper rate to provide a coating
of the specified thickness. The standard reinforcing for the cement
mortar coating shall be a spirally wound steel reinforcing wire
of the specified gauge, embedded in the coating. The wire shall be
14 gauge at 1" pitch.
Immediately after the coating has been completed, the
outside of each end of each section shall be cleaned to bare metal
and shall have the mortar troweled and shaped to suit the type of
joint being used. All bare metal exposed at the ends of each section
of .pipe shall be cleaned and suitably protected. The pipe shall then
be cured under sprinklers for not less than 7 days before being
disturbed.

B. Materials and Workmanship;
B-1. Clearing and Grubbing: All brush, roots, vegetation,
rubbish, debris, and other deleterious material shall be
removed and disposed of so as to leave the construction
site clean and neat.
B-2. Trench excavation for pipelines, fittings, valves
and appurtenances shall be as follows:
Minimum trench width shall be:
Nominal Inside Pipe Diameter Trench Width
4" through 12" Outside diameter plus 12"
14" through 24" Outside diameter plus 16"
27" through 36" Outside diameter plus 20"
Where shoring or encasement is required, tifench widths
shall be increased accordingly.
Trench depth shall be adequate to accommodate the pipe and
its foundation at the profile shown on the Plans. In the
absence of such profile grade, the top of pipe grade shall
be located 3 feet below the street subgrade or 4 feet below
existing ground at the pipe location, whichever is lower.
Pipe subgrade at the trench bottom shall have a flat or
semi-circular cross section. The bottom of the trench for
steel pipe shall be graded and prepared to provide a firm
and uniform bearing throughout the entire length of each
joint except for reauired "bell holes" at joints. Steel
pipe shall not be laid on earth mounds. Asbestos-cement
pipe shall be laid on compacted earth mounds located at one-
fifth of the pipe length from one end. Asbestos-cement coup-
lings shall not rest on the trench bottom.
Foundations in poor soil shall be constructed by removing
all soft, spongy, and deleterious materials below pipe bottom
grade to a depth determined by the District's Representative.
The void shall then be backfilled to oipe grade and cross
section with sand compacted to a minimum relative comoaction
of 90%. The replacement of unsound materials to depths of
2 feet below bottom of pipe grade shall be considered part
of the work. Replacement of materials greater than 2 feet
will be paid for as extra work.
Foundations in rock shall be constructed by removing rock
to a minimum depth of 6 inches below bottom of pipe grade
and backfilling' with sand compacted to a minimum relative
compaction of 90%.
Correction of Faulty Grades: All excavations carried below
. pipe grade shall be backfilled to proper grade and cross
•section with sand compacted to a minimum relative compaction
of 90%.

B-3. Backfill: All trenches and excavations shall be
backfilled after pipe, fittings, valves and appurtenances
have been installed.
B-3.1 Procedure in Pipe Zone: The pipe zone shall
be considered to extend from the bottom of the
excavation to 8 inches above the top of the pipe.
Backfill material from the bottom of the excavation
to the mid-point of the pipe or to a height of 12
inches above the bottom of the pipe, whichever is
lower, shall be sand (except for the earth mounds
on which asbestos-cement pipe is laid).
•Sand shall be free from foreign materials such as
dirt, rocks, sticks, vegetation, etc. and shall be
so graded that not more than 10% by weight shall
pass a No. 200 sieve. Backfill material for the
remainder of the pipe zone shall be sand or loose
soil free from stones, clods, and other deleterious
material.
Backfill shall be placed in layers simultaneously
on each side of the pipe for the full width of the
trench. Sand may be placed and compacted in layers
up to 12 inches in compacted thickness. All other
material shall be placed and compacted in layers
not exceeding 6 inches in compacted thickness.
, In placing and compacting the backfill, particular
attention is to be given to the underside of the
pipe and fittings to provide a firm support along
the full length of the pipe. Care shall be exercised
in backfilling to avoid damage to the pipe coating.
B-3.2 Procedure Above Pipe Zone: From the top
of the pipe zone to the ground surface or finish
grade, the material for backfill shall conform to
that specified for the pipe zone except that it may
contain stones up to 8 inches in diameter but shall
be so graded that at least 40% of the material
passes a No. 4 sieve. The coarser materials shall
be well distributed throughout the finer material.
Backfill material shall be placed in layers of a
thickness which can be compacted throughout to the
specified.density with compaction equipment which
will not damage the pipe and fittings.
B-3.3 Densification: All backfill shall be compacted
throughout by tamping or water settling to a minimum
• -. relative compaction of 90% or to the density required
by the agency in whose right of way the work is
located, whichever is the more compact.
Carlsbad MWD ' Earthwork (Water Mains) - 3
Tamping Method: Backfill material shall be placed
in uniform layers'of the thickness specified above.
The moisture content of the backfill material shall
be near or at the optimum required for compaction
and each layer shall 'be tamped until compacted to
the required minimum relative compaction. Heavy
duty compacting equipment having an overall weight
In excess of 125 pounds shall not be used until
backfill has been completed to a depth of 2 feet
over the top of pipe.
Water Settling Method: This method may not be used
when in the opinion of the District's Representative
(1) the backfill material is not sufficiently
granular to consolidate properly by this method,
(2) the adjacent soils are not sufficiently
pervious to permit the water to drain away, or
(3) adjacent soils or nearby structures may
be damaged.
In the pipe zone, the backfill material shall be
placed in uniform layers of the thickness specified
above. At the top of each layer, the trench shall
be diked at suitable intervals depending on the slope,
and the trench between dikes shall be filled with
sufficient water to inundate the backfill materials.
The backfill material shall then be agitated to
promote its consolidation. Care shall be exercised
to prevent floating the pipe.
Following backfilling of the pipe zone, the trench
shall be diked at suitable intervals depending
upon slope, and the trench between dikes shall be
filled and maintained with sufficient water so that
backfill materials subsequently placed will be
inundated during and following placement. The
water level shall be controlled to prevent floating
of the pipe. Backfill materials above the pipe
zone shall be placed in the water-filled trench
in uniform layers not exceeding 18 inches in thickness.
B-4. Excess Excavated Material: The Contractor shall make
the necessary arrangements for and shall remove and dispose
of all excess excavated material. In open terrain, surplus
material may be disposed of within the right of way by
.spreading, provided that rocks or lumps which cannot be
readily covered by spreading are removed.
B-5. Final Clean-Up: After backfill has been completed,
the right of way shall be dressed smooth to the contour
of the original ground and left in a neat and presentable
condition, free of all cleared vegetation, rubbish and
other construction wastes. Rocks and lumps which cannot
be readily covered by spreading shall be hauled away andCarlsbad MWD Earthwork (Water Mains) -

disposed of by the Contractor. On slopes where, in the
opinion of the District's Representative, rainfall runoff
would create an erosion problem, the Contractor shall
excavate at approximately "100-foot intervals V-type
Interception ditches to collect and carry runoff to the
low side of the right of way. The interception ditches
shall be approximately 1-foot deep and shall be skewed
approximately 45 degrees with the centerline of the right
of way.
C. Payment: Payment for earthwork and for conforming to all
the provisions included herein shall be considered to be
included in the contract unit or lump sum prices paid for the
various items of work, and no additional allowance will be
made therefor.

and the proportions of the admixture to be used shall be
fixed by the District's Representative.
B-5. Strength Requirements: All concrete shall be proportioned
to attain a minimum cylinder strength of 3,000 psi in 28
days. The compressive strengths are to be determined in
accordance with ASTM C39. Not less than 6 sacks of
cement shall be used per cubic yard.
B-6. Proportioni ng: The exact proportions of the concrete
ingredients shall be established by a material testing
laboratory selected by the District's Representative.
The Contractor shall notify the District's Representative
of his proposed source of aggregate in sufficient advance
time to permit the design of the mix. Aggregates shall be
proportioned by weight. Cement shall be proportioned by
the sack or by weight.
B-7. Mixing: The cement, sand and coarse aggregates shall
be so mixed and the quantity of water added shall be such
as to produce a homogeneous mass of uniform consistency.
Each mixer used shall be of the batch type and be of a
design to insure uniform distribution of all the materials
throughout the mass during the mixing operation, when
operated at the speed and capacity recommended by the
manufacturer and the mixer shall be so operated. Each
mixer shall be so constructed that the District's Representative
can conveniently observe the consistency and uniformity
of the concrete in the mixer during the operation.
Carlsbad MWD Portland Cement Concrete - 1
7127
Only sufficient water shall be used in mixing any class
of concrete to produce a workable mass suitable for the
particular type of construction involved. Water shall
be added prior to or during the mixer charging operation.
The mixing of each batch after all materials have been
placed in the mixer shall continue for not less than 90
seconds for a stationary mixer smaller than 2 cubic yards
in capacity and for not less than 2 minutes for a larger
stationary mixer.
If transit mix concrete is used, the mixing time shall
not be less than 3 minutes for each cubic yard of capacity.
The mixture shall be continuously agitated until all of the
concrete has been discharged from the mixer drum. The
total elapsed time between the introduction of water to
the batch and depositing the complete mix in the forms
shall not exceed 60 minutes for concrete mixed in transit
mixers. The manufacturer's guaranteed capacity of the drum
shall not be exceeded.
B-8. Placing: Concrete shall be placed only in the
presence of the District's Representative and not until
all form work, reinforcement, installation of fixtures to
be embedded, and preparation of concrete surfaces to be
bonded have been inspected and approved by him.
Concrete surfaces on or against which other concrete is
to be placed shall be thoroughly cleaned of surface laitance
and clean aggregate shall be exposed. Abrasive blast
cleaning may be required.
Each concreting operation shall be continuous until the
placing in the course, section or monolith is completed.
Fresh concrete shall not be permitted to fall from a
height greater than 6 feet without the use of adjustable
length pipes or "elephant trunks".
In order to assure that there will be no interruption in
such continuous placing, the Contractor shall have
available standby concrete mixing equipment ready for use
' in case of breakdown, or he shall make arrangements,
satisfactory to the District's Representative, with the
supplier of the concrete, if transit mix concrete is
being used, so that the District's Representative may be
assured that once placement is started it can be completed
without interruption. The vibrating equipment, including
standby equipment, shall be at the site and tested in the
presence of the District's Representative during the day
preceding the planned day of placement.
Appropriate mechanical vibration shall be used in placing
concrete to eliminate stone pockets and voids, to consolidate
each layer with that previously placed, to completely
embed reinforcing bars and other fixtures, and to bring
just enough fine material to the faces of top and exposed
surfaces to produce a smooth, dense and even texture.
Vibrators shall be of the high frequency internal type
and the number in use shall be ample to consolidate the
Carlsbad MWD Portland Cement Concrete - 2
7127
O
o
incoming concrete to a proper degree within 15 minutes
after it is deposited in the forms. In all cases, at least
2 vibrators shall be available at the site. The use of
external vibrators for compacting concrete will be permitted
when the concrete is otherwise inaccessible for adequate
compaction, provided the forms are constructed sufficiently
rigid to resist displacement or damage from external
vibration and the vibrators are approved by the District's
Representative.
B-9. Forms: All forms shall be smooth, mortar-tight,
true to the required lines and grades, and of sufficient
strength to resist any appreciable amount of springing out
of shape during the placing of concrete. All foreign
matter shall be removed from forms before concrete is placed
therein. Forms previously used shall be thoroughly cleaned
before re-use. Prior to placing concrete, all forms shall
be oiled with a high penetrating .form oil which leaves
no film on the surface that can be absorbed by the
concrete. Immediately prior to placing concrete, all forms
shall be thoroughly wetted.
Forms shall not be removed until the concrete has hardened
sufficiently to safely support its own weight and possible
construction loads. Forms supporting concrete members which
are subject to direct bending stress shall not be removed
or struck until concrete test cylinders show that a
strength of not less than 2,500 psi in compression has been
attained. In no case, however, shall forms be removed or
released prior to the expiration of 48 hours following
.placing of the concrete.
Forms for all surfaces which will not be completely
enclosed or hidden below the final surface of the ground
shall be made of surfaced plywood. Insofar as practicable,
forms shall be so constructed that the form marks will
conform to the general lines of the structure. All
sharp edges shall be chamfered with 1-inch by 1-inch
triangular fillets.
Form clamps and ties with effective water stops shall
be used to maintain accurately the specified wall
thicknesses. These ties shall be either of the threaded
or snap-off type so that no metal will be left within
1-1/2 inches of the surface of the wall. The use of twisted
wire ties will not be permitted.
B-10. Openings: Pipe sleeves, inserts for pipe connections,
anchors, and forms for pipe holes must be accurately
placed and securely fastened to the forms in such a
manner that the placing of concrete will not alter their
alignment or location.
Carlsbad MWD Portland Cement Concrete - 37127
B-ll. Joints: Construction joints shall be made only
where shown on the Plans unless otherwise approved by
the District's Representative. In case of emergency,
construction joints shall be placed as directed by the
District's Representative.
After the pour has been completed to the construction
joint and the concrete has hardened, the entire surface
of the joint shall be thoroughly cleaned of surface
laitance and clean aggregate shall be exposed by abrasive
blast cleaning. Wire brushing and air and water jets
may be used while the concrete is fresh provided results
equal to abrasive blast cleaning are obtained.
Construction joints shall be keyed. Keyways shall be
formed by bevelled strips or boards placed at right angles
to the direction of shear. Except where otherwise shown
on the Plans or specified, keyways shall be at least
1-1/2 inches in depth over at least 25 percent of the
area of the section.
When it is necessary to make a joint because of an
emergency, reinforcing steel shall be furnished and
placed across the joint as directed by the Engineer.
Furnishing and placing such reinforcing steel shall be
at the Contractor's expense and no payment will be made
therefor.
B-12. Curing: Except as described below, all newly
placed concrete shall be kept wet by the continuous
application of water for the first 7 days after the
concrete has been placed.
Concrete surfaces which will be below ground after back-
filling and minor structures, such as pipe headwalls,
pipe anchor blocks, catch basins, and the like, may be
cured by the application of pigmented curing compound.
The curing compound shall meet the specifications of
AASHO Designation: M148, Type II, White Pigmented.
Application shall be done with hand spraying equipment in
a manner satisfactory to the District's Representative.
Surfaces to be cured by the pigmented curing compound
method shall .be kept moist or wet until the curing
compound is applied, and the curing compound shall not
be applied until all patching or surface finishing has
been completed. The pigmented curing compound shall
not be applied to the surfaces of construction joints or
on reinforcing steel.
B-13. Surface Fi ni shes : During the placing of concrete,
care shall be taken in vibrating or otherwise consolidating
the concrete to insure surfaces of even texture free from
voids. Immediately after the forms have been removed,
all form bolts shall be removed to a minimum depth of
1-1/2 inches below the surface of the concrete. All
holes and depressions caused by the removal or cutting
back of such form bolts shall be cloanod and filled with
Carlsbad MWD Portland Cement Concrete - 47127 •
O
cement mortar composed of 1 part by volume of cement to
2 parts of sand. The mortar shall contain sufficient
white cement to tint the mortar to the shade of the
surrounding concrete. Care shall be exercised to obtain
a good bond with the concrete.
All rock pockets and honeycombed areas shall be repaired
by chipping back to solid concrete and filling the resulting
space in the same manner as specified for bolt holes.
This work shall be done immediately following the removal
of forms. If in the judgment of the District's Representative
rock pockets are of such an extent or character as to
affect the strength of the structure materially or to
endanger the life of the steel reinforcement, he may
declare the concrete unacceptable and require the removal
and replacement of that portion of the structure.
Except for surfaces which are to be buried, all fine and
other projections shall be removed and the surfaces shall
be brushed with stiff wire brushes or otherwise finished
until a uniform color has been obtained. The use of
carborundum stones may be required to remove unsightly
bulges or discolorations. The object of these operations
is to obtain smooth, even surfaces of uniform appearance,
free from unsightly bulges or depressions due to form
marks and other imperfections. The Contractor's attention
is called to the fact that the degree of care exercised
in building forms and the character of materials used in
formwork are the main factors affecting the amount of
finishing which will be required.
All flat work shall be finished and worked from the poured
slab and floated and troweled to a smooth, hard finish.
B-14. Reinforcement: Reinforcing bars shall be deformed
and shall be either Billet Steel Bars for Concrete
Reinforcement, ASTM Designation A-15, or A408, or Rail-
Steel Bars for Concrete Reinforcement, ASTM Designation
A16. The various grades of steel may not be used inter-
changeably in structures.
Bars shall not be bent or straightened in a manner that
would injure the material. Hooks shall conform to the
manual of standard practice of the American Concrete
Insti tute.
Main reinforcing bars shall not be spliced except as shown
on the Plans. Splices at points of maximum stress shall
be avoided. Where bars are spliced, they shall be lapped
at least 30 bar diameters and wired together to provide
a minimum distance of 2 inches between the splice and
the nearest adjacent bar or surface of the concrete.
Splices shall be staggered at least 40 bar diameters.
Carlsbad MWD Portland Cement Concrete - 57127
Metal reinforcement shall be accurately placed as shown
on the Plans and shall be securely held in position by
wiring at intersections with No. 16 or larger wire and by
using concrete spacers. The minimum spacing center to
center of parallel bars shall be three times the diameter,
but in no case shall the clear distance between bars be
less than 2 inches. All bars shall have a clear coverage
of 1-1/2 bar diameters but not less than one inch measured
from the surface of the concrete to the outside of the
bar. Metal supports may be used provided no portion of the
support extends to within 1-1/2 inches of the surface
of the concrete. Wooden supports shall not be used.
Wire mesh used for reinforcement shall be rolled flat
before placing concrete and shall be supported and tied
to prevent movement during concrete placement. Mesh shall
conform to ASTM Designation A185.
Reinforcement, at the time concrete is placed, shall be
free from rust, scale, or other coatings that would
destroy or reduce the bond.
B-15. Rubber Waterstops - Materials, fabrication, and
splices shall conform to the article on Rubber Waterstops
in Section 51 of the Standard Specifications of the
California Division of Highways dated January, 1968.
Stops shall be firmly supported during concrete placement
to prevent dislocation and to insure that ends remain at
right angles to the construction joints.
B-16 Payment - Payment for Portland cement concrete and for
conforming to all of the provisions of these Specifications
shall be considered to be included in the contract unit or lumo
sum prices paid for the various items of work and no additional
allowance will be made therefor.

provide and complete field testing and sterilization as specified.
B. Field Testing
B-l. After the pipe and all appurtenances have been laid and
backfilled sufficiently for required restraint, they shall be sub-
jected to a 4-hour hydrostatic pressure test. This test shall
consist of subjecting the pipeline to a hydrostatic pressure of 50
psi in excess of the designated working pressure specified for the
class of pipe at the low point in the section being tested. The
pressure test shall be made subsequent to any trench backfill compactive
effort with heavy duty compacting equipment having an overall
weight in excess of 125 pounds.
B-2. Maximum Length of Pipe to be included in any. one test
shall be not more than 2500 feet or the distance between valves,
whichever is greater.

least 72 hours prior to testing. While filling and immediately prior
to testing all air shall be excelled from the pipeline. Where
air valves or other suitable outlets are not available for releasing
air or applying the test, taps and fittings approved by the District's
Representative shall be installed and later securely plugged.
B-4. Procedure - The pressure in the pipeline shall be pumped
up to the specified test pressure. When the test pressure has been
reached, the pumping shall be discontinued until the pressure in
the line has dropped 25 psi, at which time the pressure shall again
be pumped up to the specified test pressure. This procedure shall
be repeated until 4 hours have elapsed from the time the specified
test pressure was first applied. At the end of this period, the
pressure shall be pumped up to the test pressure for the last time.
B-5. Leakage shall be considered as the total amount of water
pumped into the pipeline during the 4-hour period, including the
amount required in reaching the test pressure for the final time.
Leakage shall not exceed the rate of 4 gallons per inch of nominal
inside diameter per 1000 feet of pipe per 24 hours. If leakage
exceeds this rate, the weak ooints shall be located and stopped,
and all defective pipe, fittings, valves and other accessories
discovered shall be removed and replaced with sound material and

valves fittings, hydrants, service laterials, and other accessories
shall be sterilized in accordance with AWWA Specification C 601
which provides:
Chlorine gas or chlorine compound solution shall be water
mixed and introduced into the mains to form a chlorine
concentration of approximately 25 ppm or that which will
provide a minimum residual of 10 ppm in all parts of
the line after 24hours have elapsed.
During the sterilization process all valves, hydrants and other
accessories shall be operated. After chlorination, the water shall
be flushed from the line at its extremities until the replacement
water is equal chemically and bacteriologically to that of the per-
manent source of supply. The Contractor shall keep chlorine
residual testing and indicating apparatus available on the site during
the entire sterilization period,
D. Payment - Payment for field testing and sterilization
of water mains and appurtenances and for conforming to all the pro-

Operations of the permittee or contractor shall not cause a public
road to become impassable for longer than thirty (30) minute inter-
vals, unless he is specifically authorized in writing by the County
Engineer Department Construction Engineer. If operations of the
contractor do cause a public road to become impassable but for no
longer than thirty (30) minute intervals and where a detour is
not practical, he shall post and maintain at both ends of the
work a 4' x 5' sign to read in large letters, "WARNING - CONSTRUCTION
WORK. TRAFFIC SUBJECT TO A 30-MINUTE DELAY". If traffic delays
of more than thirty (30) minutes are anticipated, the contractor
shall provide a detour.
All signs to be used on a County road shall be furnished and
placed in conformance with the Planning Manual of Instruction,
Part 8, Traffic of the Department of Public Works, Division of
Highways, State of California.
(Reference is here made to a pamphlet entitled "Traffic Inter-
ference Control Manual", published by cooperation of the County of
San Diego, City of San Diego, Pacific Telephone and Telegraph
Company and San Diego Gas & Electric Company, as a manual designed
as a convenient reference guide for construction and maintenance
foremen in an effort to standardize methods of keeping traffic
flowing safely with a minimum of delay.) Its suggestions are to
be followed wherever feasible.
K. Detours. If the construction work requires a detour, written
permission shall be obtained from the Traffic Engineer of the County
Engi neer Department prior to establishment. The request for such
a permit shall be made in writing and processed via the Construction
Engineer. At the beginning and end of a detour, signs shall be
erected notifying of the detour and the direction of the traffic
flow. These signs shall be similar to Standard Type C-5-R of the
California Division of Highways and shall be at least 18 inches
high by 48 inches long, black background with the word "DETOUR"
in black letters 5 inches high in a white arrow to indicate the
direction. These signs shall be ref1ectorized. Detour signs shall
be placed on barricades at each intersection along the entire route.
L. Excavation. All earthwork shall be performed in conformance with
Section 19 of the Standard Specifications and these Special Provisions
L-1 . Maximum Length of Trenching Operations. Trenching Operation
includes all work between the point of excavation and the point
where the trench has been resurfaced and opened for traffic. The
Maximum length of trench which may be opened at any one time may
vary for specific locations because of the local traffic volume or
importance of the street. In general, the following maximum openings
will be allowed, if the traffic is cared for. These allowable lengths
may be shortened when considered necessary for the protection of
the public, in the opinion of the County Engineer
Carlsbad MWD Excavation Permit - 4
O
(a) Where the trench is cut along and under traffic lanes in
streets or alleys, and where width of trench exceeds 28 inches
and the depth exceeds 5 feet, at no time shall more than 2,000
feet of trench be under construction in any one work area, and all
work operation in one area shall be confined to not more than
750 feet of trench opened and incompletely backfilled. The re-
mainder of the area of trenching shall be available for safe
vehicular and pedestrian traffic at all times.
(b) Where width and depth of the excavation do not exceed 28
inches and 5 feet, respectively, or where the work area is outside
the traffic lanes, 4000 feet of trench may be under construction
in any one work area. In such an area,-there shall not be more
than 1400 feet of trench opened and incompletely backfilled. The
remainder of the area of trenching operation shall be available
for safe vehicular and pedestrian traffic at all times.
(c) Only when the contractor has entirely separate and complete
crews, each of which is capable of doing the entire job in
their area, will two or more operations be considered separate
work areas.
(d) Trench covered with temporary surfacing will be considered as
open to traffic. Temporary surfacing shall conform to provisions
of Paragraph 17 of these Special Provisions.
1-2. Blasting. In the event that blasting is necessary in exca-
vation, a Permit to Receive and Transport and a Burning and Blasting
Permit shall be obtained as required by the Health and Safety Code,
the Motor Vehicle Code, and the Public Resources Code. The blasts
shall be blanketed with mats or other approved protection to avoid
damage or injury to the public. Signs warning of blasting area and
requesting that radio transmitters not be used in the blasting area
shall be furnished and placed by the permittee. All blasting shall
be performed in compliance with the requirements of the State of
California "General Industry Safety Orders".
L-3. Excavated Material. Excavated material shall be deposited
along the trench side in a manner that will not obstruct the traffic
lane or cause undue inconvenience to the traveling public. If the
roadway section is not sufficient to adequately maintain through
traffic, the permittee or contractor may be required to contain or
remove the spoil material.
Carlsbad MWD Excavation Permit - 5
7127
M- Backf111. Backfill shall conform to Section 19-3.06 of the
Standard Specifications, except that Method "B" will not be permitted,
and the following modifications shall apply:
M-l. Backfill Around Utility. The specifications of the utility
company or utility district may be used where approved as a condition
of the permit by the Permit Engineer, except that where no specifi-
cations are submitted or where the specifications of the utility
company are not approved as a condition of the permit, the following
specifications shall govern:
Backfill around the pipe or utility, and to one foot above
the top of the pipe shall be a granular material, sand or
fine earth, 100% passing the 3/4" sieve and compacted to the
density required in paragraph 13-D for the depth at which
the pipe is laid. In no event shall this relative density
be'less than 85%.
M-2. Backfill to Subgrade. From one (1) foot above the top of the
pipe to the subgrade of the roadway section, the material for back-
fill may be trench spoil which shall not contain clods that will
not readily disintegrate in water, nor stones larger than six (6)
inches in diameter. This layer may contain stones, broken concrete,
bituminous pavement or oil cake ranging in size up to six (6) inches
maximum diameter in quantity not exceeding twenty-five (25) percent
of the volume when such coarse materials are well distributed through-
out the finer material.
M-3. Backfill Subgrade to Pavement. When the structural section
for the roadway shows base or subbase material (D.G. or decomposed
granite shall be assumed to mean aggregate subbase), it shall be
replaced in kind, except that the minimum section, or when there is
no definite structural section available, shall be six (6) inches
of Class 111 aggregate base furnished and placed in conformance with
Section 26 of the Standard Specifications and the following modi-
fications:
Sand Equivalent 30 Minimurn
Resistance (R) Value 75 Minimurn
Sieve Grading 3/4" Maximum

When the R valus is 75 or greater, the minimum asphalt concrete
or paving cover shall be as specified in Paragraoh 15. In the
event the base material delivered on the job site has an R Value
less than 75, but greater than 70, it may be left in place on the
job, but its reduced structural strength shall be compensated for
by providing an additional one-half (1/2) inch of asphalt surfacing,
and these sections shall be considered to be structurally equal.
In the event the R Value of the materials is less than 70, it
shall be removed from the project and replaced with suitable ma-
terial .
M-4. Compaction. The permittee shall have his compaction equipment
on the project, and the equipment shall be approved by the Con-
struction Engineer before backfilling is started. All base and sub-
base material shall be compacted to 95% relative density.
Below subbase or base to a trench depth of five (51) feet measured
from the top of the surfacing (pavement), the backfill shall be
compacted to 90% relative density. Below five feet measured down
from the top of the surfacing, the backfill shall be compacted to
85% relative density.
All densities shall be determined in accordance with the latest
revision of California Test Method No. 216, or A.S.T.M. Designation:
D-1556 and Method "C" of A.S.T.M. Designation: D-1557, (Note 2
in Method C applicable only if the percentage of plus 3/4" material
is greater than 10 percent by weight of the original sample.)
Compaction tests will be taken throughout the project to determine
whether the specified requirements have been met. The number
of tests and their location and depth shall be left to the discre-
tion of the Construction Engineer. The permittee shall excavate
holes required for compaction tests at locations designated by
the Construction Engineer and under his direction, and shall re-
fill and recompact these to the densities required by these speci-
fications for the depth tested. In areas outside the slope lines,
in the median area, and not beneath any roadway or shoulder, when
stated on the Excavation Permit, or approved by the Engineer, the
compaction may be reduced to a minimum of eighty-five (85) percent.
The permittee may backfill using any of the methods indicated below,
if approved by the Engineer.
M-4.1 Tamping Methods. When machine tamping, hand tamping or hand-
operated pheumatic tamping methods are used, the moistened fill ma-
terial shall be tamped in uniform layers not to exceed eight (8")
inches in thickness, loose measurement, unless otherwise approved
in writing by the Engineer.
M-4.2 Water'Methods. When flooding or ponding method is used, the
trench shall be diked at suitable intervals depending on the grade
of the ditch. The depth of water must be such that when earth
or sand is shoveled or pushed into the trench, it will become com-
pletely saturated. Ponding and jetting will be done in conformance
with Section 19-3.06 of the Standard Specifications.Carlsbad MWD Excavation Permit - 7
7127
trench has been initially filled and knocked down by
ling, further ponding or jetting will not be permitte
?r two feet of the trench.
After the trench
water settling, further ponding or jetting will not be permitted
in the uppei
NOTE: (a) If the permittee agrees in writing to place a temporary
fil.l and temporary surfacing and to return in a specified time
to rebuild the trench as necessary and to remove the temporary
surfacing and to replace it with a permanent cover as required
in Paragraph 18, the Construction Engineer may authorize the option
of jetting the complete trench depth and providing temporary cover,
(b) However, if the Construction Engineer determines that the water
method will soften or damage the existing roadway, or that the material
proposed for- water settling is unsatisfactory for that purpose,
water settling will not be permitted.
N. Backfill Under Obstructions. When an obstruction or other
utility or structure is encountered and the new utility must pass
under it, the area between the two utilities shall be backfilled with
subbase material, sand or gravel, free from large clods, large
stones, adobe, or any deleterious matter, and shall be rammed with
proper tools until thoroughly compacted to the density of the adjacent
material .
0. Bored and Jacked Crossing. Where, as a condition of a permit,
an open cut is not permitted, a 1/4 inch thick wall, steel casing
or pipe, with an inside diameter at least six (6) inches greater than
the maximum diameter of the utility shall be jacked under the road,
except that when a pipe of sufficient strength to be jacked under
the road is used, the steel casing will not be required, when approved
by the Engineer. While the utility is being placed or after it is
in place the area between the casing and the new pipe shall be filled
with sand. The length of the bored crossing shall be designated as
a condition of the permit.
P. Special Circumstances. On streets in commercial areas, urban
type development, or having high/traffic counts (5,000 cars per day
or greater), the convenience and safety of the traveling public
may require a higher type backfill which is installed rapidly and
surfaced immediately. In such circumstances, trench spoil will not
be allowed as backfill material. The backfill material shall be sand
compacted by wetting or material meeting the requirements for un-
treated rock base placed in loose layers eight inches thick before
tamping and compacted to 95% relative density.
The use of this paragraph and the time allowed for this "Special
Circumstance" backfill will be stated as a condition of the permit.
Only emergency work will be allowed in commercial areas between
the dates of Thanksgiving and New Year's Day.

Q. Temporary Surfacing. All trenches across paved traffic lanes
shall be provided with temporary surfacing, unless the permittee
immediately installs permanent resurfacing. The minimum requirements
for temporary resurfacing shall be steel plating or "Road-Mixed
Asphalt Surfacing" conforming to Section 38 of the Standard Specifi-
cations, except that the liquid asphalt shall be SC 800, conforming
to the latest specifications of the Asphalt Institute, and shall
have a minimum thickness of two (2) inches.
Temporary resurfacing shall be placed within twenty-four (24)
hours after completion of trench backfill and compaction and shall
be properly maintained until permanent surfacing is replaced. The
permittee will not be permitted to mix asphalt surfacing in the
traveled way unless authorized in advance by the Construction Engineer.
The permittee shall control dust as directed by the Construction
Engineer, using methods of Section 10, of the Standard Specifications.
In the rainy season (October to May), when directed by the Con-
struction Engineer, all trenches in paved traffic lanes shall be
provided with temporary resurfacing, unless the permittee immedia-
tely installs permanent resurfacing.
R. Resurfacing.
R-l. General. In all streets or alleys in which the surface is
removed, broken or damaged by equipment, or in which the ground has
caved in or settled, due to the installation of improvements, the
surface shall be restored to the original grade and crown section
by the permittee. This shall include areas beyond the actual limits
of the trench which may be damaged by equipment or by unusually heavy
traffic volume created by the trenching operations.
In the absence of specific designation of the plans, and where the
street has been improved with roadway surface, base course, curb,
sidewalk or gutter, trenches or damaged sections shall be restored
with the type of improvement conforming to that which existed at the
time the permittee entered upon the work. All work shall match the
appearance of the existing improvements and finished pavement shall
not deviate from existing grade, and shall be free from ruts, depressions
and irregularities.
In all streets or alleys which are not paved but are traveled by the
public, the surface of the area disturbed by the permittee's operations
shall be replaced to a depth of at least six (6) inches with Class 111
aggregate base conforming with Section 26 of the Standard Specifications
and as modified in Paragraph 13 (c).
