instructed to utilize detail M111/TYP found on sheet GM03.

QUESTIONS AND RESPONSES

Question No. 1: Reference specification section 15000 2.2 E 1.i. Flange Fasteners are called out to be

Carbon Steel ASTM A307 Grade A with a TRIPAC 2000 blue coating system. Please confirm Carbon

Steel bolts with TRIPAC 2000 blue coating are to be used for all flange material types whether Ductile

Iron, PVC, CPVC, Stainless Steel or Carbon Steel and the same for all flange locations, specifically

exposed chemical systems and submerged applications. Or should 316 Stainless Steel be used in certain

locations in lieu of the Carbon Steel bolts with TRIPAC 2000 blue coating?

Response to Question No. 1: Please reference specification sections 15000 2.2.E.2, 3, and 4 which

provides further clarification regarding corrosive and non-corrosive service applications, as well as

material groups for various pipe materials.

Question No. 2: An air scour assembly is shown on sheet M123 of the plans. Can you confirm that this

assembly begins at the 1-1/2” SST Universal Air Coupler that is not attached to anything and injects into three of

the 12” backwash pipes at the Service Saddle with Corp Stop?

Response to Question No. 2: Confirmed. The system provides a manual air connection point.

Question No. 3: The NDEP permit in Appendix C was listed as valid between August 28th, 2017 and February

24th, 2018. Has this permit been extended to incorporate our project time frame?

Response to Question No. 3: This permit will be extended for the project duration.

Question No. 4: Reference the pipe schedule on sheet G012. System test pressure requirements are provided in

this schedule, but service pressures are not. Note 1 for detail M803 found on sheet GM07 states that “all

components for piping systems with service pressure class greater than 150 PSI shall be suitable for the higher

pressure.” Currently there is no way to determine what operating pressures will be or if this note is applicable.

Please identify what the maximum service pressure is for all systems. Also, the High Pressure Butterfly Valves

are called out to have a bolt pattern of ANSI Class 300 flanges in spec section 15202 (which would be per ANSI/

ASME B16.1 Class 250). If maximum service pressures are under 250 psi, can the Butterfly Valve bolt pattern be

in accordance with ANSI/ ASMA B16.1 Class 125, which is rated for 250 psi?

Response to Question No. 4

All components shall be suitable for the test pressures indicated.

Question No. 5: Sheet C210 (Yard Piping) indicates the 8” SLW buried pipe line to be material type PE05. The

pipe schedule on sheet G012 indicates the pipe material for the buried service SLW to be SS02. Please confirm

which pipe material is required for the buried SLW service.

Response to Question No. 5: Pipe material shall be PV05 as indicated on drawing C210.

Question No. 6: Also, sheet M280 indicates the same pipe line to be 8” SWL. Please confirm the correct

designation for this 8” pipe service.

Response to Question No. 6: The correct pipe designation is “8” SLW”.

Question No. 7: Reference specification section 15030 for Stainless Steel Pipe. 1.2 D states that welders are to

be NSF 61 certified. The National Sanitation Foundation does not certify people. Typically certifications are

provided for the materials used to confirm compliance with the NSF 61 standard. Please confirm only Stainless

Steel Pipe materials will need to be NSF 61 certified, not individuals.

Response to Question No. 7: Stainless Steel Pipe materials and fabricators will need to be NSF 61 certified. See

modification to specification 15030 as described below in Specifications Section.

Notes: 1. Not all major products and systems are included in the table above; only those items related to mechanical equipment. Other products, such as concrete, steel and piping are not included. 2. Items in this table must be circled or completed for the bid.

Bidders are advised that the Owner has made a finding that particular materials, products, things and services are designated by specific brand or trade name in order to match other materials, products, things or services in use or to obtain necessary items available only from one source. By listing a sole-source vendor, Owner has only identified a particular product the supply of which will conform to the Contract. Owner does not warrant in any respect the performance of any designated sole-source vendor. Owner shall not be responsible for, and Contractor shall not be excused for, any failure of a sole-source vendor to supply a conforming product in a timely fashion. Bidders shall refer to individual specification sections for specific requirements.

Contractors, manufacturers or suppliers or materials and equipment may offer an alternative product and request the alternatives to specified products be considered equal, unless the Owner has sole-sourced a product. Inclusion of such alternatives in the bid is the sole responsibility of the Contractor. Inclusion of the proposed alternative should only be considered if it is the Contractor’s sole belief the offered alternative is equal in quality and performance to the specified product. After award of the Contract, such offers of alternative products will be reviewed and processed. If the material, equipment, process or article offered by the Contractor is not, in the Owner’s sole opinion, substantially equal or better in respect to that specified, then the Contractor shall furnish that material, process or article specified or one that in the Owner’s opinion is substantially equal or better in every respect.

Article 5 Bonds and Insurance

5.01 Performance and Payment Bonds

A. The Contractor shall furnish Performance and Payment Bonds, issued by a “T” listed bond company acceptable to TMWA, signed or countersigned by an agent licensed by the State of Nevada as required by NRS 680A.300, each in the amount of 100 percent of the Contract Sum as security under the Contract Documents for faithful performance and payment of all obligations under the Contract Documents, including but not limited to warranty obligations. Contractor shall furnish such bonds to TMWA no later than ten (10) calendar days after receipt of the Notice of Award.

B. If the surety on any bond becomes insolvent or its right to do business is terminated, the Contractor shall provide another bond and surety, acceptable to TMWA within seven days.

C. The Bonds shall remain in effect for a period of one year from the date of final completion and acceptance of the Project by TMWA.

D. The cost of additional bond premiums for change order increases shall be a pass-through cost to TMWA for the actual amount of the additional bond premiums.

5.02 Contractor’s Insurance A. Contractor shall, at Contractor’s sole expense, procure, maintain and keep in force the following

insurance and pay all taxes and fees incident hereunto. The required insurance shall be in effect prior to the commencement of work by Contractor under this Agreement. TMWA shall have no liability except as specified in this Agreement. Contractor shall furnish evidence of such insurance to TMWA no later than ten (10) calendar days after receipt of the Notice of Award.

B. Contractor shall include all Subcontractors under its policy(ies) or shall contractually require all of its Subcontractors to procure, maintain and provide evidence of insurance coverage with limits no less than those required herein. When Subcontractors provide separate coverage, they shall include TMWA as an additional insured under their commercial general liability without requiring a written contract or agreement between the additional insured and Subcontractor. When requested by TMWA, CONTRACTOR shall furnish copies of certificates of insurance evidencing coverage for each subcontractor. CONTRACTOR shall require its Subcontractors provide appropriate certificates and endorsements from their own insurance carriers naming CONTRACTOR and TMWA as additional insureds.

C. Any insurance or self-insurance available to TMWA shall be excess of and non-contributing with any insurance required from Contractor. Contractor’s insurance policies shall apply on a primary basis. Until such time as the insurance is no longer required by TMWA, Contractor shall provide TMWA with renewal or replacement evidence of insurance no less than 30 days before the expiration or replacement of the required insurance. If at any time during the period when insurance is required by the Agreement, an insurer or surety shall fail to comply with the requirements of this Agreement, as soon as Contractor has knowledge of any such failure, Contractor shall immediately notify TMWA and immediately replace such insurance or bond with an insurer meeting the requirements.

D. By endorsement to all liability policies, except Worker’s Compensation and Professional Liability, evidenced by Contractor, TMWA, its officers, employees and immune Contractors as defined in NRS 41.0307, if any, shall be named as additional insured for all liability arising from the Agreement. This insurance shall apply as primary insurance with respect to any other insurance or self-insurance programs afforded to TMWA. Additional insured status for TMWA shall apply until the expiration of time within which a claimant can bring suit per applicable state law.
