Project Title: REHABALITATE WATER TANK

1.2 Scope

In accordance with the terms and conditions of the Contract, the Contractor shall perform the work for the National Park Service (NPS) as described below.

In addition, there is an “Information” section (http://www.nps.gov/dscw/information.htm) which provides design requirements and criteria that shall be used for completing the work of this contract. The “Information” section provides links to the following:

· Forms/Templates/Samples/Guidelines (http://www.nps.gov/dscw/publicforms.htm): A listing of forms/templates/samples/guidelines used for a typical project.

· Laws/Regulations/Policies/Guidance (http://www.nps.gov/dscw/laws-policies.htm): A listing of sources for retrieving laws/regulations/policies/guidance applicable to NPS projects.

1.3 Location

This project is located in and directly adjacent to the developed Visitor Center and Housing Area at Sunset Crater National Monument (SUCR) in Coconino County, Arizona. The SUCR Visitor Center area is located at 6082 Sunset Crater Rd, Flagstaff, AZ, 86004. The Visitor Center Area is located appx. 5 miles East on FS 545 (Wupatki Loop Road) from the intersection of FS 545 and US Highway 89. The intersection of US Highway 89 and FS 545 is appx 18 miles north of Flagstaff, AZ. The elevated water storage tank has good accessibility for vehicles and equipment.

A pre- award site visit is greatly encouraged to determine site conditions and site limitations to conventional equipment. The contractor shall make every effort to minimize impact to the site and the natural surroundings by limiting off road travel. The date and time of the site visit will be noted in the solicitation sent to the Contractors.

1.4 Background

The elevated water storage tank was constructed in 1966 and has been properly maintained since. This has left the tank in good condition but requires minor rehabilitation to reach the full design life. In an effort to reduce impact on the surrounding resources all considerations will be made to use minimal impact. Contractor will be responsible for proper disposal of all materials. The water tank provides services to a visitor center (2 restrooms, a water fountain, and other points of service), a maintenance facility, 2 residential housing units, a 2-unit apartment building, 4 trailer pads, and a seasonal campground with 2000 GPD used on average, and various points of service (yard hydrants, spigots, fire hydrants).

1.5 Description

The park seeks to:

Rehabilitate the existing elevated water tank at SUCR to comply with OSHA, AWWA regulations. A temporary water supply in compliance with all ADEQ guidelines must be provided while existing tank is out of commission. All water quality testing stipulated by ADEQ must be preformed prior to rehabilitated tank being brought back into service. All applicable ADEQ paper work will be provided to park.

1.6 Schedule

The work in this RFP shall be completed in accordance with the following schedule:

Construction:

Construction shall not begin until the Contracting Officer (CO) has issued the Notice to Proceed.

Construction shall be completed no later than 180 calendar days after award of the contract.

2.3.14 Substantial Completion and Final Inspection

Submit written certification to the Contracting Officer (CO) that the project, or designated portion of project, is substantially complete, and request a final inspection. Upon receipt of written request that project is substantially complete, the CO will proceed with inspection within 10 days of receipt of request or will advise the Contractor of items that prevent the project from being designated as substantially complete.

When work is determined to be substantially complete, the CO will prepare a list of deficiencies ("Punch List") to be corrected before final acceptance. The CO will issue a Letter of Substantial Completion. If work is not determined to be substantially complete, the CO will notify the DBC in writing. After completing work, the DBC shall resubmit certification and request a new final inspection.

If, following final inspection, the work is determined to be substantially complete, CO will prepare a list of deficiencies to be corrected before final acceptance and issue a Letter of Substantial Completion. Contractor shall complete the work described on the list of deficiencies within 30 calendar days, as weather permits. If the Contractor fails to complete the work within this time frame, the CO may either replace or correct the work with an appropriate reduction in the contract price or charge for re-inspection costs in accordance with the Inspection of Construction clause of the contract.

Acceptance of the work: After all deficiencies have been corrected, the CO will issue a Letter of Final Acceptance.
