All information given in the Contract Documents relating to subsurface and other conditions, natural phenomena, existing pipes, and other structures is from the best sources presently available to the Owner. All such information is furnished only for the information and convenience of Bidders and is not guaranteed.

It is further agreed that no Bidder or Contractor shall use any of the information made available to him or obtained in any examination made by him in any manner as a basis of or ground for any claim or demand against the Owner or the Engineer, arising from or by reason of any variance which may exist between the information made available and the actual subsurface or other conditions, natural phenomena, existing pipes or other structures actually encountered during the construction work, except as may otherwise be expressly provided for in the Contract Documents.

CONNECTICUT SALES AND USE TAX. Materials purchased for permanent installation in the work will be exempt from the Connecticut Sales and Use Tax under the Connecticut Education, Welfare and Public Health Tax Act. Each Bidder shall take this exemption into account in calculating his Bid for the work.

ALTERNATES. Bidders must submit prices for all alternates. Bids omitting a price for any alternate may be considered incomplete and subject to rejection. The Owner reserves the right to award the contract on the basis of that combination of alternates which appears to be in the best interest of the Owner.

To this end, the Owner reserves the right to reduce the quantity of any items of the Bid, either prior to executing the contract or at any time during the progress of the work. The Owner further reserves the right, at any time during the progress of the work, to restore all or part of any items previously omitted or reduced. Exercise by the Owner of the above rights shall not constitute any ground or basis of claim for damages or for anticipated profits on the work omitted.

20. INFORMATION NOT GUARANTEED

All information given on the Drawings or in the Bid Documents relating to subsurface and other conditions, natural phenomena, existing pipes, and other structures is from the best sources at present available to the Owner. All such information is furnished only for the information and convenience of bidders and is not guaranteed.

It is agreed and understood that the Owner does not warrant or guarantee that the subsurface or other conditions, natural phenomena, existing pipes or other structures encountered during construction will be the same as those indicated on the drawings or in the Bid Documents.

It is agreed and understood that no bidder or contractor shall use or be entitled to use any of the information made available to him or obtained in any examination made by him in any manner as a basis of or ground for any claim or demand against the Owner or the Engineer, arising from or by reason of any variance which may exist between the information made available and the actual subsurface or other conditions, natural phenomena, existing pipes or other structures actually encountered during the construction work, except as may otherwise be expressly provided for in the Bid Documents.

Omissions from the plans and specifications shall not relieve the Contractor from the responsibility of furnishing, making or installing all items required by law or usually furnished, made or installed in a project of the scope and general character indicated by the plans and specifications.

TECHNICAL SPECIFICATIONS

TS-1

TECHNICAL SPECIFICATIONS

The Ductile Iron 250 PSIG Insert Valve shall be a Resilient Wedge Gate Valve designed for use in potable water control systems. The design will allow the valve to be installed into an existing pressurized pipeline while maintaining constant pressure and service as usual.

Ductile Iron Construction:

• The ductile iron body, bonnet and wedge provide strength and a pressure rating that meets or exceeds the requirements of AWWA C515. Insert Valve shall be ductile iron construction meeting ASTM A536 Grade 65-45-12. Heavy-duty ductile iron construction for maximum toughness and strength.

• Chemical and modularity tests shall be performed as recommended by the Ductile iron Society, on a per ladle basis. Testing for tensile, yield and elongation shall be done in accordance with ASTM E8.

• 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.

• 250 PSIG maximum working pressure. The pressure rating markings must be cast into the body of the insert valve.

Resilient Wedge Gate Assembly:

• The construction of the Resilient Wedge shall comply with AWWA C509 requirements.

• The ductile iron wedge shall be fully encapsulated with EPDM rubber by a high pressure and high temperature compression or injection mold process. This will ensure the ductile gate is fully coated with molded rubber – no exposed iron.

• The resilient wedge shall seat on the valve body and not the pipe to obtain the optimum seating and flow control results. The resilient wedge shall be totally independent of the carrier pipe.

• The resilient wedge shall not come into contact with the carrier pipe or depend on the carrier pipe to create a seal. Abrasion results thus shortening the life and quality of the shut down if the wedge contacts the pipe.

• Pressure equalization on the down or upstream side of the closed wedge shall not be necessary to open the valve.

• The wedge shall be symmetrical and seal equally well with flow in either direction.

TS-2

Fusion-Bonded Epoxy:

• The insert valve is fully epoxy coated on the interior and the exterior. The fusion-bonded coating is applied prior to assembly so that even the bolt holes and body-to-bonnet flange surfaces are fully epoxy coated.

• Valve shall be coated with a minimum of 8 mils epoxy in compliance with AWWA C550 and certified to ANSI/NSF-61.

Gaskets and Triple O-Ring Stem Seals:

• The insert valve features triple O-Ring stem seals. Two O-Rings are located above, and one O-Ring is located below the thrust collar.

• The lower two O-Rings provide a permanently sealed lubrication chamber that will make the valve easier to operate over a longer period of time. The upper O-Ring ensures that sand, dirt or grit cannot enter the valve to cause damage to the lower O-Rings.

• Side flange seals shall be of the O-Ring type of either round, oval, or rectangular cross-sectional shape.

Valve Stem & Thrust Washers:

• The gate valve stem and wedge nut shall be copper alloy in accordance with Section 4.4.5.1 of the AWWA C515 Standard.

• The NRS stem must have an integral thrust collar in accordance with Section 4.4.5.3 of AWWA C515 Standard. Two-piece stem collars are not acceptable. The wedge nut shall be independent of the wedge and held in place on three sides by the wedge to prevent possible misalignment.

• Two thrust washers are used. One is located above, and one is located below the stem thrust collar.

Two thrust washers ensure easy operation at all times.

• NRS with AWWA standard turns.

• Operated by 2” square wrench nut according to ASTM A126 CL.B. All valve inserts shall be of the Open Left (black nut) type.

American Made Quality:

• All parts and components to be exclusively and completely assembled, manufactured, machined and coated in the USA.

• All physical and chemical test results shall be recorded such that they can be accessed via the identification number on the casting. These Material Traceability Records (MTR’s) are to be made available, in hard copy, to the purchaser that requests such documentation.

• All components shall be manufactured and assembled in the United States. The purchaser shall, with reasonable notice, have the right to plant visitation at his/her expense.

TS-3

Hardware:

• Bolting materials shall develop the physical strength requirements of ASTM A307 with dimensions conforming to ANSI B18.2.1.

Extended Life Value:

• The stuffing box, operating stem and resilient wedge (complete bonnet and all moving parts) shall be removable, repairable and or replaceable under pressure.
