TRAIL DESIGN STANDARDS
Hard Surface Trails
2. Design Standards
a. Prepared Sub -grade -Over-excavate unstable subgrade soils where encountered and
replace with city approved fill material. Compact all fill to 95% standard proctor @ -
2% to +4% optimum. Remove all topsoil prior to subgrade preparation and use in
finish grading work along trail edges after concrete has cured. Import additional soil
backfill as needed for trail edges to provide a minimum 5 foot wide trail shoulder and
an embankment blended with existing grade on both sides of the trail. All
embankments must be constructed at mowable slopes (4:1 grade or less).
b. Pavement Structure — The standard pavement is reinforced Portland cement concrete
(concrete mix: 5 -sack, 3,000 pounds/square inch minimum, 3-5 inch slump, 100/0 fly
ash content maximum) with a transverse light to medium broom finish. One inch (14
mm) redwood expansion joints shall be placed in the trail at an interval of 30 feet in 10'
wide trails and 40 feet in 12' trails. Expansion joints shall be topped and sealed with a
minimum thickness of ''/d' elastomeric sealer compound, flush with the top surface of
pavement on both sides of the joint. Contraction joints shall be placed at intervals equal
to the trail width and shall be of a depth of one-fourth the pavement thickness. The
joints shall be saw -cut one-fourth inch (3.175 mm) wide. For optimum user comfort,
the finished surface of trails should not vary more than .02 feet (0.63 cm) from the
lower edge of an 8 -foot (2.4 m) long straight edge when laid on the surface in any
direction. The trail concrete thickness shall be 5 inches minimum. The reinforcement
Ordinance No. 2593-2-07, Page IS
shall be #3 (minimum) deformed steel bar at a maximum of 16 inches on center. both
ways, on chairs (welded wire mesh is not acceptable). Doweled expansion and
. construction joints, where new trail pavement is connected to existing pavement shall
consist of #5 deformed steel bar, spaced at 12" o.c. along the pavementjoint.
C. Width & Clearance — Trails on which a mix of bicycle, pedestrian and other non -
motorized transportation, and large maintenance vehicles, are required to navigate steep
grades, should be 12 feet (3.7 m) wide. Otherwise, a 10 foo[ (3 m) width is adequate.
The minimum width of a one -directional bicycle path is 10 feet for maintenance access
and passing room for cyclists. One-way bicycle paths often will be used as two-way
facilities unless effective measures are taken to assure one-way operation.
The optimum vertical clearance of obstructions over a trail is 10 feet (3 m) or higher, which
accommodates maintenance, patrol, and emergency vehicle access. All underpasses and tunnels should be
a minimum of 10 feet in height. The standard minimum vertical clearance is 8 feet (2.4 m). If vertical
clearances under bridges and other structures is less than 10 feet, the clearance shall be clearly posted
with warning signage to alert approaching trail users. Tree branches over trails shall be cleared to this
height unless otherwise directed by the Parks and Recreation Department.
A 5 -foot minimum (1.8 m) wide graded shoulder shall be constructed and maintained adjacent to both
sides of the trail surface. Two feet (0.6 m) is the minimum width for the adjacent graded area; although a
3 -foot (0.92 m) width clearance shall be provided from trees, poles, walls, fences, guardrails, etc. or their
lateral obstructions whenever possible. In instances where trees or other obstacles may encroach within
this space, warning signage should be provided. A 5 -foot (1.8 m) lateral separation is desirable from any
embankment that the cyclist would have difficulty encountering. If this is not possible, a positive barrier
such as dense shrubbery, safety railing, walls, or fencing shall be provided. All barrier material shall
' conform to City of Allen standards
L Drainage
The trail developer shall install vegetation or other erosion control measures on both sides of
the trail and other areas impacted by construction. Erosion control matting or similar materials
may be accepted in times of mandatory local water consumption restrictions.
j. AASHTO Compliance
Where site conditions preclude trail construction that complies entirely with AASHTO
guidelines for bicycle facilities development, or make such construction impractical, the City
has the authority to require the trail developer to install or construct other trail features that
compensate for the non-compliance. This may include but not be limited to warning signs,
additional safety railings and bariers, clearing of vegetation and/or removal of other obstacles
(e.g, utilities).
C. Trail Crossing Structures
Where bridges and trailheads are shown on the Allen Trails Implementation Plan, the developer of the
property on which those improvements are shown shall be required to construct those improvements and
in accordance with the Land Development Code. If a bridge is required, where the developer only owns
' one side of the creek or waterway to be crossed, the City may accept funds in escrow for one-half of the
bridge or crossing.
1. Pedestrian Bridges
Ordinance No. 2593-2-07, Page 19
a. Trail crossings over creeks shall be by bridge (see subsection "b" for crossings over
ravines and small streams). Pre -fabricated bridges require approval by the City. Bridges
' shall be of arched -truss design and shall be designed to comply with ADA criteria. The
minimum width of any bridge shall be 2 feet wider than the widest trail connecting to the
structure, e.g., a 10' wide trail shall be served by a 12' wide bridge.
b. Design bridges that are sturdy, safe, vandal resistant and easily maintained:
L Deck shall be of iron wood/ipe wood.
ii. The deck members shall be stabilized to minimize vibrations, and shall
be fastened to the sub -structure at the outside edges and at a minimum of
two intermediate stringers running the full length of the deck.
iii. Railing shall be free of splinters and provide a smooth, clean surface to
the much.
iv. Railing design shall allow views to creeks for persons of all heights, yet
prevent anyone from falling through.
V. Scale of bridge shall be in keeping with its surroundings.
vi. Bridge color shall blend with the natural environment or relate to the
color scheme of adjacent development.
vii. Integrate design with other elements throughout the creek corridor.
' E. Culvert Outfall Structures
1. Design Objectives
Many existing culvert pipe structures may need modification to meet trail safety and aesthetic
standards. Culvert outfalls shall occur on the downhill side of trails.
2. Culvert Crossings
Culvert crossings may be used at creek tributaries or ravines with the approval of the City. In all
cases, the following shall apply:
a. Culvert crossings shall be capable of supporting loads of City maintenance
vehicles, and designs shall be sealed by a Texas professional engineer.
b. There shall be no untrimmed metal or plastic culvert piping exposed at upstream
and downstream faces of the structure.
C. Culvert crossings shall have an upstream and downstream retaining wall
supporting the trail, and shall be wide enough to accommodate the trail width
plus a three
(3) feet shoulder on both sides of the trail width for the entire length of the
crossing. The retaining wall shall be faced and capped with a veneer of mortared
stone or a patterned concrete.
d. All side slopes shall be fine -graded and protected with heavy-duty erosion
control blanket, pinned per the manufacturer's recommendations.
Ordinance No. 2593-2-07, Page 20
e. All crossings shall include safety railing, powder -coated with no exposed
' uncoated metal.
3. Low Water Crossings
1
1
a. Low water crossings may be used only where the vertical distance from the trail surface
elevation to the flow line of the waterway is three (3) feet or less. In all situations, the decision to
allow a low-water crossing in lieu of a culvert crossing will be made by City staff. Any crossing
that exceeds this three-foot separation shall require a culvert crossing or a bridge.

Portland cement concrete, separate silos shall be provided for fly ash and cement and
Ordinance No. 2593-2-07, Page 58
provisions shall be made for individual measurements.
' (h) Finishing
Delete (h) and add the following: The finished concrete pavement construction under
these specifications is expected to meet certain quality standards for surface of the
concrete including the durability, texture, riding surface and appearance. The surface
must be durable, firm, dense and well bonded to the aggregate to maintain an appearance
and texture which is satisfactory to the Owner. Concrete pavement having a poor
surface which has spalled (exposed aggregate) due to poor quality paste, high water -
cement ratio, over -vibration, improper curing, extreme weather or any other reason, or
does not have a satisfactory riding surface shall be removed and replaced at the
Contractor's expense. It is extremely important that the pavement have a good rideable
surface, free from undulations and rough Joints The City Engineer shall determine the
acceptability of the pavement.
(1) Machine Finishing
Machine finishing of pavement shall include the use of power -driven spreaders,
reciprocating type power -driven vibmtors, power -driven transverse strike -off, and
screed.
The concrete pavement shall be consolidated by a reciprocating type mechanical
vibrator. As soon as the concrete has been spread between the forms, the mechanical
vibrator shall be operated to consolidate the concrete and remove all voids. Hand
manipulated vibrators shall be used for areas not covered by the mechanical vibratory
unit.
The transverse finishing machine shall first be operated to compact and finish the
pavement to the required section and grade, without surface voids. The machine shall
be operated over each area as many times and at such intervals as directed. At least
two trips will be required and the last trip over a given area shall be a continuous ran of
not less than 40 feet. After completion of finishing with the transverse finishing
machine a transverse drag float may be used.
After the floating has been completed and the excess water removed, but while the
concrete is still plastic, the surface of the concrete shall be tested for trueness with an
approved 10 -foot steel straightedge furnished by the Contractor. The straightedge shall
be operated from the side of the pavement, placed parallel to the pavement centerline
and passed across the slab to reveal any high spots or depressions. The straightedge
shall be advanced along the pavement in successive stages of not more than one-half
its length. Practically perfect contact of the straightedge with surface will be required,
' and the pavement shall be leveled to this condition, in order to insure conformity with
the surface test required below after the pavement has fully hardened and to insure a
smooth rideable surface. Any correction of the surface required shall be accomplished
Ordinance No. 2593-2-07, Page 59
by adding concrete if required and by operating the longitudinal float over the area.
The surface test with the straightedge shall then be repeated.
' After completion of the straightedge testing and surface correction, the surface of the pavement shall
be finished by an approved method. Methods available for pavement surface finish include a burlap
drag finish, a broom finish or belt finish. Unless otherwise shown on the plans, the pavement surface
shall be finished with the burlap drag.
a. Burlap Drag Finish
If the surface texture is to be a drag finish, a drag shall be used; it shall consist of a seamless strip of
damp burlap or cotton fabric, and it shall produce a uniform surface of gritty texture after dragging it
longitudinally along the full width of pavement. For pavement 16 feet or more in width, the drag
shall be mounted on a bridge which travels on the forms. The diameter of the drag shall be such that a
strip of burlap or fabric at least 3 feet wide is in contact with the full width of pavement surface while
the drag is used. The drug shall consist of not less than two layers of burlap with the bottom layer
approximately 6 inches wider than the upper layer. The drag shall he maintained in such a condition
that the resultant surface is of uniform appearance and reasonable free from grooves over I/16 -inch in
depth. Drags shall be maintained clean and free from encrusted mortar. Drags that cannot be cleaned
shall be discarded and new drags substituted.
' b. Broom Finish
If the surface texture is to be a broom finish, it shall be applied when the water sheen has practically
disappeared. The broom shall be drawn from the center to the edge of the pavement with adjacent
strokes slightly overlapping. The broom operation shall be so executed that the corrugation produced
in the surface shall be uniform in appearance and not more than 1/16 -inch in depth. Brooming shall
be completed before the concrete is in such condition that the surface will be tom or unduly
roughened by the operation. The surface thus finished shall be free from rough and porous areas,
irregularities, and depressions resulting from improper handling of the broom. Brooms shall be the
quality, size, and construction and shall be operated to produce a surface finish meeting the approval
of the Owner. Subject to the approval of the Owner, the Contractor may be permitted to substitute
mechanical brooming in lieu of the manual brooming as herein described.
c. Belt Finish
If the surface texture is to be belt finish, when straightedging is completed and after sheen has
practically disappeared and just before the concrete becomes non -plastic, the surface shall be belted
with a 2 -ply canvas belt not less than 8 inches wide and at least 3 feet longer than the pavement
width. Hand belts shall have suitable handles to permit controlled, uniform manipulation. The belt
shall be operated with short strokes transverse to the centerline and with a rapid advance parallel to
the centerline.
' (2) Hand Finishine
Hand finishing of concrete pavement will be permitted in areas where it is not practical or
Ordinance No. 2593-2-07, Page 60
possible to construct with finishing machines. These areas include, but are not limited to,
intersections, left turn lanes, crossovers, transition areas and where the pavement width is
' not uniform. In all hand finished areas, one (1) extra sack of cement per cubic yard of
concrete shall be used in the mix. In hand finished areas, the concrete shall be struck off
with an approved strike -off screed to such elevation that when consolidated and finished
the surface of the pavement shall conform to the required section and grade. The strike
template shall be moved forward with a combined transverse and longitudinal motion in
the direction the work is progressing, maintaining a slight excess of material in front of
the cutting edge. The concrete shall then be tamped with an approved tamping template
to compact the concrete thoroughly and eliminate surface voids and the surface screeded
to required section. After completion of a strike -off, consolidation and transverse
screeding; a hand -operated longitudinal float shall be operated to test and level the
surface to the required grade.
Workmen shall operate the float from approved bridges riding on the forms and spanning
the pavement. The longitudinal float shall be held in contact with the surface and parallel
to the centerline and operated with short longitudinal strokes while being passed from
one side of the pavement to the other. If contact with the pavement is not made at all
points, additional concrete shall be placed, if required, and-screeded, and the float shall
be used to produce a satisfactory surface. Care shall be exercised to keep the ends of the
' float from digging into the surface of the pavement. After a section has been smoothed
so that the float maintains contact with the surface at all points in being passed from one
side to the other, the bridges may be moved forward half the length of the float and the
operation repeated. Other operations and surface tests shall be as required for machine
finishing.
(3) Edging at Forms and Joints
After the final finish, but before the concrete has taken its initial set, the edges of the pavement along
each side of each slab, and on each side of transverse expansion joints, formed joints, transverse
construction joints, and emergency construction joints shall be worked with an approved tool and
rounded to the radius required by the plans. A well-defined and continuous radius shall be produced
and a smooth, dense, mortar finish obtained. The surface of the slab shall not be unduly disturbed by
tilting of the tool during use.
At all joints, any tool marks appearing on the slap adjacent to the joints shall be eliminated by
brooming the surface. In doing this, the rounding of the edge shall not be disturbed. All concrete on
top of the joint filler shall be completely removed.
All joints shall be tested with a straightedge before the concrete has set, and correction shall be made
' if one side of thejoint is higher than the other or if they are higher or lower than the adjacent slabs.
ITEM 5.8.6 PAVEMENT TESTING
Ordinance No. 2593-2-07, Page 61
(b) Pavement Thickness Test
Delete in its entirely and substitute therefore the following:
Upon completion of the work and before final acceptance and final payment shall be
made, pavement thickness tests shall be made by the Contractor. Tests shall be made at
400 foot spacings along the length of the pavement. In the event a deficiency in the
thickness of pavement is revealed, two (2) subsequent tests necessary to isolate the
deficiency shall be made - one at a jointed section prior to the deficient station and one
at a jointed section following the deficient station. Additional tests shall be obtained as
necessary, at jointed section intervals to isolate the deficient area. Removal and
replacement of concrete shall extend to joint boundaries, the full width of pavement
section. If the average thickness of pavement in a particular section is less than called
for on the plans, the pavement section shall be removed and replaced with the correct
thickness, extending to joint boundaries, the full width of the pavement section, at the
Contractor's entire expense. No additional payment over the contract unit price shall be
made for any pavement of a thickness exceeding that required on the plans.
(c) Pavement Strength Test -Amend the first paragraph to read: During the progress of the
work, the Inspector or a commercial laboratory shall cast test cylinders or beams to
maintain a check on the strengths of the concrete being placed. Add the following
sentence and table: A table titled "PAVEMENT STRENGTH REQUIREMENTS", is
' provided showing the required pavement thickness, 7 -day strength, 28 -day strength,
minimum cement factor and maximum slump for each street type to be constructed in
Allen. Requirements for high strength pavement and less thickness is also shown, if
required by the City.
Add to the 5th paragraph: Test cores shall be obtained within five (5) working days after
the 28 -day test results have been provided by the commercial laboratory. All test cores
shall be obtained by a commercial laboratory, at the Contractors expense. One (1) core
shall be obtained in the immediate area of the deficiency and two (2) additional cores
shall be obtained - one at a jointed section prior to the deficient station and one at a
Jointed section following the deficient station: Additional cores shall be obtained as
necessary, at jointed section intervals to isolate the deficient area. Removal and
replacement of concrete shall extend to joint boundaries, the full width of pavement
section.
Amend the last paragraph on Page 293 to read "Pavement not meeting the minimum
specified 28 -day strength after cores have been tested shall be removed and replaced at
the Contractor's expense." Delete the table and the paragraph below it at the top of Page

Delete the first two sentences in its entirety and substitute therefore the following:
(a) General
On construction projects in the City of Allen in which excavation will exceed a depth of five
feet, the bid documents and the contract must include provisions specifications for detailed
plans for excavation safety systems. The term "excavation" includes trenches, structural or
any construction which has earthen excavation made below the surface of the ground
whereby the depth is greater than the width, but the width is less than 15 feet. A trench may
consist of the void between the wall of the excavation and the wall of a structure, concrete
' form, pipe, etc., provided the structure wall or other type of structure is within 15 feet of the
excavation wall.
Prior to execution of a contract the Contractor will be required to submit an excavation safety
plan for the project. This excavation safety plan must be designed and sealed by a
professional engineer registered in the State of Texas. The professional engineer registered in
the State of Texas. The professional engineer shall not be a principal in the contracting
company nor have a monetary interest in the Contractor's firm. The Contractor is responsible
for obtaining borings and soil analysis as required for plan design. The excavation safety plan
shall be designed in conformance with occupational Safety and Health Administration
(OSHA) standards and regulations. Contracts will not be awarded with unsatisfactory safety
records. Evaluation will be based on:
(a) Contractors' safety record based on Occupational Safety and Health
Administration (OSHA) records.
(b) Based on past performance related to safety on City of Allen projects.
(c) Contractors will be required to submit a notarized affidavit with their bid attesting
to their safety record.
' After evaluation of the excavation safety plan, the City Engineer will forward the reviewed
plan to the appropriate City construction division for use in inspection. Plans for
construction will not be released by the City Engineer until this plan is reviewed. Changes
Ordinance No. 2593-2-07, Page 64
in the excavation safety plan after initiation of construction may not be cause for extension
of time or change order, and will require the same review process. Contractor accepts sole
' responsibility for compliance with all applicable safety requirements. The review is only
for general conformance with OSHA safety standards. Release of the excavation safety plan
by the City Engineer does not relieve Contractor from any or all construction means,
methods, techniques and procedures; and any property damage or bodily injury (including
death) that arises from use of the excavation safety plan from Contractor's negligence in
performance of contract work, or from City's failure to note exceptions to the excavation
plan, shall remain the sole responsibility and liability of the Contractor. The Contractor
agrees to indemnify and hold harmless the City, its officers, employees and agents from and
against any and all claims for property damage or bodily injury (including death) that arise
out of or result from any act or omission pertaining to any excavation work whether or not
caused in whole or in part by the negligent act or omission of the City, its officers,
employees of agents. A separate pay item for excavation safety and support shall be
included in the bid documents. A separate pay item for the Engineer's design of the safety
and support system shall also be included.
Contractors have three ways to meet OSHA Standards for excavation safety. They are as
follows:
' (1) Minimum Angle of Repose - the greatest angle above the horizontal plane at which a
material will lie without sliding.
(2) Utilization of Trench Box.
(3) Shoring, Sheeting and Bracing Methods.
The following minimum design criteria must be followed by Contractors electing to utilize the
Minimum Angle of Repose:

sewer pipe through the manhole and breaking out the top half after the base is
' constructed. Inverts shall extend up at least half of the diameter of the pipe. Changes in
the direction of the sewer and entering branches shall have a true curve of as large a
radius as the size of the manhole will permit. Where the pipe is laid through the
manhole, the invert shall be finished to 1/4 -inch below the center of the pipe. The pipe
shall be trimmed down to 1/4 -inch below the surface of the invert, and the edges of the
pipe along the invert and at the walls of the manhole shall be plastered and brash -
finished. Plaster shall be 2 -parts of masonry sand to 1 -part of Portland cement, or an
approved non -shrink grout.
Delete 5th paragraph of (c) Tests and Television Inspection (bottom of Page 329) which reads "Tunneled,
bored or jacked sections of pipe shall be tested by exfiltration only."
(d) Manhole Barrel Section: There vertical forms, wall spaces, and placing cone most be
carefully positioned and firmly clamped in place before any placement is made. The wall
spacers must be located 90 degrees from each other. The manhole shall be cast of 4000
psi concrete with a maximum slump of 4 inches. The first placement shall consist of
approximately 1/2 yard of concrete evenly around the walls and vibrated until there is a
minimum slump of 60 degrees from the bottom of the forms to the bearing surface both
inside and outside of the manhole. When this is complete and before additional concrete
' is added, the concrete must be carefully vibrated on each side of each pipe. Additional
concrete must be deposited in evenly distributed layers of about 18 inches with each layer
vibrated to bond it to the preceding layer. The will spacers must be raised as the
placements are made with the area from which the spacer is withdrawn being carefully
vibrated. Excessive vibration is to be avoided. A maximum of 2% calcium chloride may
be added to the concrete, at the Contractors option, to speed the set. The forms may be
removed as soon as the concrete has sufficiently set (approximately 2 hours after
placement depending on field conditions).
Form marks and offsets up to l -inch will be permitted on the outside surface of the manhole. Form marks
and offsets up to 1/2 -inch will be permitted inside the manhole. All offsets on the inside surface of the
manhole will be smoothed and plastered so there is no projection or irregularity capable of scratching a
worker or catching and holding water or solid materials. Honeycomb will be plastered with a mortar
consisting of 3 pars of masonry sand and 1 -part Portland cement upon removal of the forms, but not until
after being inspected for structural integrity by the Owner or his authorized Representative. Manholes
deemed to be structurally unsound shall be replaced.

ITEM 6.7.2 (f) AIR TESTING
Completely replace subsection 6.7.2 (f), Air Testing with the following text:
(f) Low Pressure Air Testin¢
(1) General. The CONTRACTOR shall furnish adequate personnel and equipment
required to perform the tests. This test covers procedures for testing sewer pipe lines,
wben using the low
pressure air test method to demonstrate the integrity of the installed pipe line and the
construction procedures. This test is used for testing flinch to 33 -inch circular sewer
pipe lines utilizing gasketedjoints. Mains 36 -inch and larger may be tested by the
individual joint method.
(2) I-hstorv. The low pressure air test was developed to enable detection of damaged
pipe or improperjointing and is a test which determines the rate at which air under
pressure escapes from an isolated section of sewer. The rate of air loss is intended to
indicate the presence or absence of pipe damage and whether or not the joints have
been property constructed. The test is not intended to indicate water leakage limits
and cannot be used as a measure of infiltration or exfiltration leakage under service
conditions.
(3) Testing Methods. The two most common air test methods used are the "Constant
Pressure Method" and the "Time Pressure Drop Method." The contractor may utilize
either of these methods of low pressure air testing.
(a) Preparation of the sewer line to be tested: The section of sewer line to
be tested shall be flushed and cleaned prior to conducting the low pressure air
test. This serves to clean out the debris, wet the pipe, and produces the most
consistent results.
(b) Test Procedures: 1) Isolate the section of sewer line to be tested by means
of inflatable stoppers or other suitable tests plugs. The ends of all branches,
laterals, tees, wyes and stubs to be included in the test should be plugged to
' prevent air leakage. All plugs should be securely braced to prevent possible
blow-out due to -the internal air pressure. One of the plugs should have an
inlet tap, or other provision for connecting a hose to a portable air control
Ordinance No. 2593-2-07, Page 71
(c) Constant Pressure Method: 1) Air is supplied to the pipe test section
at a rate sufficient to maintain a gage pressure of 3.0 psi. The rate of air flow
in cubic feet per minute is read directly by the means of a rotometer. The
rate of air flow shall be corrected for pressure and temperature under
standard conditions. 2) The requirements for air loss under the "Constant
Pressure" method shall be considered satisfied if the air loss does not exceed
a rate of 0.003 cfm per square foot of internal pipe surface area with a total
rate of air loss not greater than 2.0 cubic feet per minute, based on a wetted
pipe.
(d) Time Pressure Drop Method: 1) Air is slowly introduced into the section
of pipe to be tested, until the air pressure is raised to approximately 4.0 prig.
The air shall be allowed to stabilize for a period of two minutes. The air
supply is disconnected and the test pressure allowed to decrease to 3.5 psig.
The time required for the test pressure to drop from 3.5 psig to 2.5 psig is
determined, and this time interval is then compared to the required time to
' determine if the rate of air loss is within the allowable. 2) Minimum holding
times required per pipe diameter are shown in the table "Duration
Requirements for Air Testing." (Note: Test times are independent of the line
Ordinance No. 2593-2-07, Page 72
source. 2) Connect the air hose to the inlet tap and a portable air control
'
source. The air equipment should consist of necessary valves and pressure
gages to control the rate at which air flows into the test section and to enable
monitoring of the air pressure within the test section. Also, the testing
apparatus should be equipped with a pressure relief device to prevent the
possibility of loading the test section with the full capacity of the compressor.
3) Add air slowly to the test section until the pressure inside the pipe is raised
to 4.0 psig. 4) After a pressure of 4.0 psig is obtained, regulate the air supply
so that the pressure is maintained between 3.5 and 4.0 psig for a period of
two minutes. This allows the air temperature to stabilize in equilibrium with
the temperature of the pipe walls. The pressure will normally drop slightly
until equilibrium is obtained. During this period all assessable plugs should
be checked with soap solution to detect any plug leakage. 5) Determine the
rate of air loss by either the constant pressure method or the time pressure
drop method.. For the constant pressure method, air is supplied to the pipe
test section at a rate sufficient to maintain a gage pressure of 3.0 psi. The rate
of air flow in cubic fcet per minute is read directly by means of a rotometer.
The rate of air flow must be corrected for pressure and temperature under
standard conditions. 6) Upon completion of the test, the bleeder valve is
opened and all air is allowed to escape. Plugs should not be removed until all
air pressure in the test section bas been released. Also no one should be
allowed in the trench or manhole while the test is being conducted.
(c) Constant Pressure Method: 1) Air is supplied to the pipe test section
at a rate sufficient to maintain a gage pressure of 3.0 psi. The rate of air flow
in cubic feet per minute is read directly by the means of a rotometer. The
rate of air flow shall be corrected for pressure and temperature under
standard conditions. 2) The requirements for air loss under the "Constant
Pressure" method shall be considered satisfied if the air loss does not exceed
a rate of 0.003 cfm per square foot of internal pipe surface area with a total
rate of air loss not greater than 2.0 cubic feet per minute, based on a wetted
pipe.
(d) Time Pressure Drop Method: 1) Air is slowly introduced into the section
of pipe to be tested, until the air pressure is raised to approximately 4.0 prig.
The air shall be allowed to stabilize for a period of two minutes. The air
supply is disconnected and the test pressure allowed to decrease to 3.5 psig.
The time required for the test pressure to drop from 3.5 psig to 2.5 psig is
determined, and this time interval is then compared to the required time to
' determine if the rate of air loss is within the allowable. 2) Minimum holding
times required per pipe diameter are shown in the table "Duration
Requirements for Air Testing." (Note: Test times are independent of the line
Ordinance No. 2593-2-07, Page 72
length once the minimum holding time has been reached.)
' (4) Individual Joint Test Method: All concrete sewer mains 36 -inch and larger in
diameter shall be 100% air tested at each joint connection only. The method of
testing shall be described in Item 6.7.2(f 0. The time allowed for the pressure drop
from 3.5 psi to 2.5 psi shall be 10 seconds. No joint shall be air tested until the pipe
has been backfilled. Air testing shall be performed as pipe installation progresses. At
no time shall pipe installation exceed 100 feet from the last joint tested. If the joint
fails to pass the joint air test, necessary repairs as recommended by the pipe
manufacturer may be made if approved by the OWNER and the joint retested. Failure
to pass the air test atter repairs have been made may be cause of rejection.

NOTES: SILT FENCE
1. Posts which support the silt fence shall be installed on a slight angle
toward the anticipated runoff source. The post must be embedded a minimum
of 18 inches.
2. The toe of the silt fence shall be trenched in with a spade or mechanical
trencher, so that the downslope face of the trench is flat and
perpendicular to the line of flow. Where fence cannot be trenched in
(e.g. pavement), weight fabric flap with washed grave on the uphill side to
prevent flow under fence.
3. The trench must be a minimum of 6 inches deep and 6 inches wide to
allow for the silt fence fabric to be laid in the ground and backfilled with
compacted material.
4. Silt fence shall be securely fastened to each support post or to woven wire,
which is in turn attached to the support post. There shall be a 6 inch double
overlap, securely fastened where ends of fabric meet.
5. Inspection shall be made daily or after each rainfall. Repair or
replacement shall be made promptly as needed.
6. Silt fence shall be removed when the site is completely stabilized so as
not to block or impede storm flow or drainage.
7. Accumalated silt shall be removed when it reached a depth of 3 inches. The
silt shall be disposed of at an approved site and in such a manner as to
not contribute to aditional siltation.
