LIQUIDATED DAMAGES: Upon execution of the contract, the Contractor shall proceed with the preparation and submittal of shop drawings and his tentative construction schedule and with subsequent ordering and fabricating of materials. The Owner will issue a written "Notice-to-Proceed" which will specify an effective date for the Contractor to begin work at the site. The construction shall be substantially completed within one hundred-forty (140) calendar days of the Notice to Proceed issuance. At the time of substantial completion, the Owner shall have beneficial use of the Triturator Upgrade. Final completion shall be within two hundred (200) calendar days of the Notice to Proceed. Should work continue beyond time specified above, and no time extension has been granted via the Change Order process, then liquidated damages will be assessed to the Contractor for each and every calendar day the work remains uncompleted. Refer to FAA Section 80 for specific information about Notices to Proceed, completion dates, and liquidated damages. Such deducted sums shall not be deducted as a penalty but shall be considered, as liquidation of a reasonable portion of damages that will be incurred by the Owner should the Contractor fail to complete the work in the time provided in his/her contract. The undersigned affirms that in making such bid, neither he or she nor any company that they may represent, nor anyone in behalf of him or her or their company, directly or indirectly, has entered into any combination, collusion, undertaking or agreement with any other bidder or bidders to maintain the prices of said work, or any compact to prevent any other bidder or bidders from bidding on said Contract or work and further affirms that such bid is made without regard or reference to any other bidder or proposer and without any agreement or understanding or combination either directly or indirectly with any other person or persons with reference to such bidding in any way or manner whatsoever. The bidder shall furnish similar statements executed by each of his or her subcontractors to all subcontractor’s subcontractors whose contracts equal Ten Thousand Dollars ($10,000.00) or more and shall obtain similar compliance by such Subcontractors before awarding such Subcontractors. No subcontract shall be awarded to any non-complying Subcontractor. The undersigned further agrees that if awarded the Contract he or she will commence the work within ten (10) Calendar days after the date of the Notice to Proceed and that he or she will complete the work in accordance with the Summary Schedule and Key Milestones and Substantial Completion date set forth in the Bidding and Contract Documents or such amended date as may be granted. If the undersigned fails to complete the work as provided in the aforementioned schedule, then and in that event, he or she further expressly agrees that, for each day that any phase of work under this Contract remains uncompleted thereafter the Owner may deduct from the Contract price herein specified the stipulated sum of liquidated damages as provided in the Special Provisions and retain that sum for failure of the undersigned to complete this Contract on or before the expiration of the period shown in the completion schedule. In submitting this bid, it is understood that the right is reserved by the Owner to the fullest extent permitted by law to waive any informality or irregularity in any bid or bid guaranty, to reject any and all bids, to re-bid, to award or refrain from awarding a contract for the work and to negotiate with the apparent qualified low responsive bidder to such extent as may be beneficial to the Owner in its sole discretion. The undersigned attaches hereto a (cashier’s check), (certified check) (Bid Bond) in sum of _____________________________________________________________________________ Dollars, ($___________________________), payable to the Rhode Island Airport Corporation, as required in the Information to Bidders, and the undersigned agrees that in case he or she fails, within five (5) calendar days after Notice of Intent to Award the Contract to him or her, to enter into a Contract Agreement in



writing and furnish the required Payment and Performance Bonds, with surety or sureties to be approved by Owner, and insurance policies or endorsements, the Owner may, as its option, determine that the undersigned has abandoned his rights and interest in such bid and that the cashier's check, certified check, or Bid Bond accompanying his or her bid has been forfeited. Otherwise, the cashier's check, certified check, or Bid Bond shall be returned to the undersigned upon the execution of the Contract and acceptance of the bonds and insurance, or upon rejection of his or her bid. A bid shall be considered unresponsive and shall be rejected if it fails to include fully executed statements or if the Bidder fails to furnish required data. When a determination has been made to award the Contract to a specific Contractor, such Contractor shall, prior to award, furnish such other pertinent information regarding his or her own employment policies and practices as well as those of his or her proposed Subcontractors as the Owner may require. The bidder shall furnish similar statements executed by each Subcontractor and their Subcontractors whose contracts equal Ten Thousand Dollars ($10,000.00) or more and shall obtain similar compliance by such Subcontractors before awarding such Subcontractors. No subcontract shall be awarded to any non-complying Subcontractor. The undersigned affirms that he or she has completed all of the blank spaces in the "Bid Form", with an amount in words and numbers and agrees that where a discrepancy occurs between the prices quoted in words and/or in numbers the words shall take precedence and govern when determining final costs or award of Contract.

PART 2 - PRODUCT 2.1 Pump Design

A. The manufacturer of the pumps must be ISO 9001:2000 revision certified, with scope of

registration including design control and service after sales activities. B. Pumps shall be custom designed, integral, vertical rotor, motor driven, solids handling

pumps of the progressing cavity type with a single mechanical seal capable of handling raw domestic sanitary sewage. Pump solids handling capability and performance criteria shall be in accordance with requirements listed under PART 1 - GENERAL of this section.

C. Materials and Construction Features

1. All pump castings shall be cast iron, fully epoxy coated to 8-10 mil Nominal dry

thickness, wet applied. The rotor shall be through-hardened, highly polished, precipitation hardened stainless steel.

2. The stator shall be of a compounded ethylene propylene synthetic elastomer. This

material shall be suitable for domestic wastewater service. Its physical properties shall include high tear and abrasion resistance, grease resistance, water and detergent resistance, temperature stability, excellent aging properties, and outstanding wear resistance.

3. The grinder shall be immediately below the pumping elements and shall be direct-

driven by a single, one-piece motor shaft. The grinder impeller (cutter wheel) assembly shall be securely fastened to the pump motor shaft by means of a threaded connection attaching the grinder impeller to the motor shaft. The grinder impeller shall be a one-piece, 4140 cutter wheel of the rotating type with inductively hardened cutter teeth. The cutter teeth shall be inductively hardened to Rockwell 50 – 60c for abrasion resistance. The shredder ring shall be of the stationary type and the material shall be white cast iron. The teeth shall be ground into the material to achieve effective grinding. The shredder ring shall have a staggered tooth pattern with only one edge engaged at a time, maximizing the cutting torque.

4. This assembly shall be dynamically balanced and operate without objectionable

noise or vibration over the entire range of recommended operating pressures. The grinder shall be constructed so as to minimize clogging and jamming under all normal operating conditions including starting. Sufficient vortex action shall be created to scour the tank free of deposits or sludge banks which would impair the operation of the pump. These requirements shall be accomplished by the following, in conjunction with the pump

a. The grinder shall be positioned in such a way that solids are fed in an

upward flow direction. b. The maximum flow rate through the cutting mechanism must not exceed 4

feet per second. This is a critical design element to minimize jamming and as such must be adhered to.



c. The inlet shroud shall have a diameter of no less than 5 inches. Inlet shrouds that are less than 5 inches in diameter will not be accepted due to their inability to maintain the specified 4 feet per second maximum inlet velocity which by design prevents unnecessary jamming of the cutter mechanism and minimizes blinding of the pump by large objects that block the inlet shroud.

d. The impeller mechanism must rotate at a nominal speed of no greater than 1800 rpm.

D. Serviceability

1. The pump manufacturer shall demonstrate to the engineer's satisfaction that

consideration has been given to reducing maintenance costs by incorporating the following features.

2. No special tools shall be required for replacement of any components within the

pump.

E. Spare Parts

2. There shall be furnished with the pump station the following minimum spare parts:

One spare pump mechanical seal (complete), and with it all gaskets, seals, sleeves, O-rings, and packing required to be replaced during replacement of the seal.

2.2 Valves and Piping

A. Check Valve:

1. The discharge of each pump shall be equipped with a factory installed, gravity operated, flapper-type integral check valve built into the discharge piping. The check valve will provide a full-ported passageway when open, and shall introduce a friction loss of less than 6 inches of water at maximum rated flow.

2. Moving parts will be made of a 300 Series stainless steel and fabric reinforced

synthetic elastomer to ensure corrosion resistance, dimensional stability, and fatigue strength. A nonmetallic hinge shall be an integral part of the flapper assembly providing a maximum degree of freedom to assure seating even at a very low back-pressure. The valve body shall be an injection molded part made of an engineered thermoplastic resin.

3. The working pressure of the valve shall be at least 235 psi. Ball type check valves

are unacceptable due to their limited sealing capacity.

B. Anti-Siphon Valve:



1. The discharge of each pump shall be equipped with a factory-installed, gravity-operated, flapper-type integral anti-siphon valve built into the discharge piping.

2. Moving parts will be made of 300 Series stainless steel and fabric-reinforced

synthetic elastomer to ensure corrosion resistance, dimensional stability, and fatigue strength. A nonmetallic hinge shall be an integral part of the flapper assembly, providing a maximum degree of freedom to ensure proper operation even at a very low pressure.

3. The valve body shall be injection-molded from an engineered thermoplastic resin.

Holes or ports in the discharge piping are not acceptable anti-siphon devices due to their tendency to clog from the solids in the slurry being pumped. The anti-siphon port diameter shall be no less than 60% of the inside diameter of the pump discharge piping.

C. Air Release Valve:

1. The Sewage Combination Air Valves shall combine an Air & Vacuum large orifice

and an automatic small orifice in a single body. The valve shall be specially designed to operate with liquids carrying solid particles such as wastewater and effluent. The combination air valve shall discharge air (gases) during the filling or charging of the system, admit air to the system while draining and at water column separation and discharge accumulated air (gases) from the system while operating under pressure. The valve's design shall guarantee separation of the liquid from the sealing mechanism and provides optimum work conditions. The valve shall discharge air at high flow rates, without premature closing.

2. The Sewage Combination Air valve shall be capable of operating at working

pressure range of 3 - 150 psi. The valve shall be certified to a test pressure of 250 psi at a working temperature of 140° F. The valve shall be rated for a maximum working temperature for short time period: 194° F.

3. Valve body shall be either Stainless Steel SAE 316 or Reinforced Nylon and shall

not contain any corrosive materials in the body and mechanism. All internal metal parts shall be of stainless steel. Internal floats shall be made of composite materials. The valve design shall prevent any contact between wastewater and the sealing mechanism by creating an air gap at the top of the valve. This air gap shall be guaranteed even under extreme conditions.

4. The valve body shall be a conical body shape designed to assure a large initial

air/gas pocket, to maintain the maximum distance between the liquid and the Sealing Mechanism; while allowing minimum body height. A spring supported joint between the stem and the upper float shall be provided to assure that vibrations of the lower float will not unseal the air release orifice of the air valve.

5. Release of air will occur only after enough air accumulates. A Rolling Seal

Mechanism in the valve design shall be utilized as it is less sensitive to pressure changes than a direct float seal. The rolling seal mechanism is required as it allows a comparably large orifice for a wide pressure range (up to 150 psi).



6. The lower body shall be funnel-shaped to ensure that residue wastewater matter will drain to the pipe and be to be carried away by the flow, and will not remain in the valve. The upper body shall have a 1 1/2" threaded discharge outlet which shall enable removal of excess fluids.

7. The valves shall be furnished with flanged ends to meet ASA 150 standard. Smaller

valves of 2”, 3” valves may be supplied with NPT male threads.

D. Piping

1. Each pump shall be furnished with a discharge hose and fittings for easy removal and replacement of each pump core. The piping shall be constructed of polypropylene, EPDM or PVC. The discharge hose assembly shall include a shut-off valve rated for 200 psi WOG and a quick disconnect feature to simplify installation and pump removal. The bulkhead penetration shall be factory installed and warranted by the manufacturer to be watertight. The assembly shall include a redundant full union ball valve to be installed on the pump discharge connection prior to the discharge hose making it capable for the removal of the pump core at the pump connection or at the basin connection. Hose shall be of sufficient length to enable removal of the pump core from the pump connection without being excessively long.
