any rights or remedies of City against Contractor then existing or which may thereafter accrue, or any rights or remedies of City against Contractor or Surety. Any retention or payment of money due Contractor by City will not release Contractor from liability.

3.4 INSTALLATION 1
A. Placement 2
1. Place CLSM by any method which preserves the quality of the material in terms of 3
compressive strength and density: 4
a. Limit lift heights of CLSM placed against structures and other facilities that 5
could be damaged due to the pressure from the CLSM to 4 feet or the lift height 6
indicated on the Drawings, whichever is less. 7
1) Do not place another lift of CLSM until the last lift of CLSM has set and 8
gained sufficient strength to prevent lateral load due to the weight of the 9
next lift of CLSM. 10
b. The basic requirement for placement equipment and placement methods is the 11
maintenance of its fluid properties. 12
c. Transport and place material so it flows easily around, beneath, or through 13
walls, pipes, conduits, or other structures. 14
d. Maintain slump developed for trial batch during construction at all times within 15
1-inch +/-. 16
e. Use a slump, consistency, workability, flow characteristics, and pumpability 17
(where required) such that when placed, the material is self-compacting, self 18
densifying, and has sufficient plasticity so compaction or mechanical vibration 19
is not required. 20
f. When using as embedment for pipe take appropriate measures to ensure line 21
and grade of pipe. 22
3.5 REPAIR [NOT USED] 23
3.6 RE-INSTALLATION [NOT USED] 24
3.7 SITE QUALITY CONTROL 25
A. Quality Control Testing 26
1. Perform testing to determine whether the CLSM, as being produced during the 27
process of construction, is in accordance with the requirements of this Section. 28
a. Make and deliver test cylinders to testing laboratory at the Contractor’s 29
expense. 30
2. Test cylinders 31
a. Prepare test cylinders in accordance with ASTM C31 with the following 32
exceptions: 33
1) Fill the concrete test cylinders to overflowing and tap sides lightly to settle 34
the mix. 35
2) Do not rod the concrete mix. 36
3) Strike off the excess material. 37
b. Place the cylinders in a safe location away from the construction activities. 38
Keep the cylinders moist by covering with wet burlap, or equivalent. Do not 39
sprinkle water directly on the cylinders. 40
c. After 2 days, place the cylinders in a protective container, such as a Styrofoam 41
or similar lining that will limit the jarring and bumping of the cylinders, for 42
transport to the laboratory for testing. 43

d. Place test cylinders in a moist curing room. Exercise caution in moving and 1
transporting the cylinders since they are fragile and will withstand only 2
minimal bumping, banging, or jolting without damage. 3
e. Do not remove the test cylinder from mold until the cylinder is to be capped 4
and tested. 5
f. The test cylinders may be capped with standard sulfur compound or neoprene 6
pads: 7
1) Perform the capping carefully to prevent premature fractures. 8
2) Use neoprene pads a minimum of 1/2 inch thick and 1/2 inch larger in 9
diameter than the test cylinders. 10
3) Do not perform initial compression test until the cylinders reach a 11
minimum age of 3 days. 12
3. The number of cylinder specimens taken each day shall be determined by the City. 13
a. Test 1 cylinder at 3 days and 2 at 28 days in accordance with ASTM C39 14
except as modified herein. 15
b. The compression strength of the cylinders tested at 28 days shall be equal to or 16
greater than the minimum required compression strength, but not exceed 17
maximum compression strength. 18
4. Test the air content of the CLSM. Test will be made immediately after discharge 19
from the mixer in accordance with ASTM C231. 20
5. Test the slump of CLSM using a slump cone in accordance with ASTM C143 with 21
the following exceptions: 22
a. Do not rod the concrete material. 23
b. Place material in slump cone in 1 semi-continuous filling operation, slightly 24
overfill, tap lightly, strike off, and then measure and record slump. 25
6. If compressive strength of test cylinders does not meet requirements, make 26
corrections to the mix design to be in accordance with the requirements of this 27
Section. 28

2. Wrap all buried steel flanges for AWWA C200, C301, or C303 pipe with a 20
Petrolatum Tape System in accordance with AWWA C217. 21
a. If only 1 flange in a joint is steel (AWWA C200, C301, or C303), petrolatum 22
tape wrapping will be required. 23
b. If a joint is made between two ductile iron flanges, the joint should be 24
polyethylene encased in accordance with Section 33 14 10. 25
3. During assembly, tighten nuts gradually and equally using a three-pass method in 26
accordance with ASME PCC-1-2012. 27
a. First pass 28
1) Tighten the nuts to 50 percent at diametrically opposite sides to prevent 29
misalignment and to ensure that all bolts carry equal loads. 30
b. Second pass 31
1) Tighten the nuts to 100 percent again in a diametrically opposite pattern. 32
2) Allow a minimum of 1 hour to pass to provide time for settlement between 33
bolts and nuts and gasket relaxation. 34
c. Third pass 35
1) Check each bolt in a clockwise pattern. Each nut should be tightened until 36
it will no longer turn. This step compensates for elastic interaction and 37
brings all bolts into parity. 38
4. The threads of the bolts should protrude a minimum of 1/2-inch from the nuts. 39

g. Deflection Design 6
1) Base pipe design on pipe stiffness, soil stiffness, and load on the pipe. 7
2) Design pipe according to the Modified Iowa Formula as detailed by the 8
Uni-Bell PVC Pipe Association in the Handbook of PVC Pipe, using the 9
following parameters: 10
a) Unit Weight of Fill (w) = 130 pounds per cubic foot 11
b) Live Load = AASHTO HS 20 12
c) Trench Depth = 12 feet minimum, or as indicated in Drawings 13
d) Maximum (E’) = 1,000 max 14
e) Deflection Lag Factor (DL) = 1.0 15
f) Bedding Factor constant (K) = 0.1 16
g) Mean radius of the pipe (r), inches, as indicated in Drawings 17
h) Marston’s load per unit length (W), pounds per inch, calculate per 18
Drawings 19
i) PVC modulus of elasticity (E) = 400,000 psi 20
j) Moment of inertia of pipe wall per unit length, (I) = t3/12, (in4/in), per 21
pipe type and size 22
(1) Where (t) = pipe thickness, inches 23
k) Maximum Calculated Deflection = 5 percent 24
25
h. Pipe Flotation: If the pipe is buried in common saturated soil (about 120 pounds 26
per cubic foot) with at least 1½ pipe diameters of cover, pipe is generally not 27
subject to flotation. If shallower, check groundwater flotation potential. 28
Flotation will occur if: 29
30
Fb > Wp + Wf + Wd 31
32
Where: Fb = buoyant force, pound per foot 33
Wp = empty pipe weight, pound per foot 34
Wf = weight of flooded soil, pound per foot 35
Wd = weight of dry soil, pound per foot 36
37
Values and formulas for the above variables can be obtained from the pipe 38
manufacturer and site-specific soil conditions. 39
i. Verify trench depths after existing utilities are located. 40
j. If vertical alignment changes due to an existing utility or other conflict, verify 41
whether change in required pipe design stiffness is required. 42
k. In no case shall pipe be installed deeper than its design allows. 43

Insertion Valves
1. DESCRIPTION
Furnish labor, materials, and equipment necessary to provide installation of an insert valve in conformance
with the plans and specifications, and in compliance with the Department’s Utility Accommodations Policy
(Title 43, T.A.C., Sections 21.31-21.55). Construct Insertion Valves of the sizes, materials, and dimensions
shown on the plans including pipe, and connections to new and existing pipes as many as may be required
to complete the work.
The abbreviations AWWA, ASA, ASTM, ANSI, AASHTO, NACE, NSF, SSPC, and TCEQ used in this
specification refer to the following organizations or technical societies:
AWWA American Water Works Association,
ASA American Standards Association,
ASTM American Society for Testing and Materials,
ANSI American National Standards Institute,
AASHTO American Association of State Highway and Transportation Officials,
NACE National Association of Corrosion Engineers,
NSF National Sanitation Foundations,
SSPC Steel Structural Painting Council, and
TCEQ Texas Commission on Environmental Quality.
References to specifications of the above organizations mean the latest standard or tentative standard in
effect on the date of the proposal.
2. MATERIALS
All materials must conform to the requirements of this Item, and the plans.
2.1. General. Provide new and unused materials for this project unless otherwise stated in the plans or proposal.
2.2. Insertion Valves will be a resilient wedge gate valve designed for use in potable water, raw water, reclaimed
water, sewage, and irrigation. The design will allow the valve to be installed into an existing pressurized
pipeline while maintaining constant pressure and service as usual. After closing the wedge and adequately
restraining the valve body the downstream pipe can be completely removed and replaced (allowing for
upsizing of the pipe if necessary). The host pipe must not be a permanent component of the Insertion Valve.
Insertion Valves must have a stainless steel or ductile iron body with a pressure rating that meets or exceeds
the requirements of AWWA C515. The heavy-duty ductile iron construction should meet ASTM A536 Grade
65-45-12. Sizes 12” and smaller must be capable of working on Cast/Grey Iron or Ductile Iron Class A, B, C
and D, IPS PVC, C900 and C909 PVC, Steel, AC pipe diameters without changing either top or bottom
portion of split valve body.
The Insertion Valves will be fully epoxy coated on the interior and the exterior and the coating must be
applied before assembly. The Insert Valve must be coated with a minimum of eight mils epoxy in compliance
with AWWA C550 and certified to ANSI/NSF-61.
7216
2 - 2 07-19
OTU
The construction of the resilient wedge must comply with AWWA C509 requirements. The ductile iron wedge
will be fully encapsulated with EPDM rubber by a high pressure and temperature compression or injection
mold process. This will assure the ductile gate is fully coated with molded rubber-no exposed iron. The
resilient wedge must seat on the valve body and not the pipe to obtain the optimum seating and flow control
results. The resilient wedge will be totally independent of the carrier pipe. The resilient wedge must not
come into contact with the carrier pipe or depend on the carrier pipe to create a seal. Pressure equalization
on the down or upstream side of the closed wedge will not be necessary to open the valve. The wedge must
be symmetrical and seal equally well with flow in either direction. The resilient wedge must ride inside the
body channels to maintain wedge alignment throughout its travel to achieve maximum fluid control
regardless of high or low flow pressure or velocity.
Valves must have a gate valve stem and wedge nut that is stainless steel in accordance with Section 4.4.5.1
of the AWWA C515 Standard and must be capable of being installed under a line pressure of up to 250 psi
without service disruption.
The NRS stem must have an integral thrust collar in accordance with Section 4.4.5.3 of AWWA C515
Standard. The valve bolting materials must develop the physical strength requirements of ASTM A307 with
dimensions conforming to ANSI B18.2.1.
The stuffing box, operating stem and resilient wedge will be removable, repairable and or replaceable under
pressure.
The split restraint device must consist of multiple gripping wedges incorporated into a follower gland meeting
ANSI/AWWA C110/A21.10. The devices must have a working pressure rating of 350 psi for 4-12”. Gland
body wedges and wedge actuating components must be cast from grade 65-45-12 ductile iron material in
accordance with ASTM A536. Mechanical joint restraints must require conventional tools and installation
procedures per AWWA C600, while retaining full mechanical joint deflection during assembly as well as
allowing joint deflection after assembly.
2.3. Contractor will submit shop drawings and vendor product information for approval by the engineer.
3. CONSTRUCTION
3.1. Contractor to follow vendor specifications for proper installation of Insertion Valve.
4. MEASUREMENT
4.1. Insertion Valves. Measured by each assembly installed.
5. PAYMENT
The work performed and materials furnished in accordance with this Item and measured as provided under
“Measurement” will be paid for at the unit prices bid for the items of work described below. These prices are
full compensation for furnishing, hauling, placing, and installing the materials; for inspecting and testing; and
for other materials, labor, equipment, tools, and incidentals.
5.1. Insertion Valves. Payment for insert valves will be made at the unit price bid for “Insertion Valve,” of the
various sizes specified, with the valve box installed.
