This is currently an unfunded requirement with a high expectation that funds will be available. When and if funds become available a contract will be awarded at that time.

The NAICS Code for this requirement is 237990 with a size standard of $45 million.

Description:

The project is located in Water Barge Cove near Callville Bay in Lake Mead National Recreation Area, Las Vegas, NV.

The construction magnitude is $5M-10M.

The surrounding area is rural with limited staging located at Abandoned Loop D Campground, the Existing Generator Site, or the UV Enclosure and Generator Site Plateau.

The Project site has significant access challenges due to steep topography of the location and limited existing access roads/points.

The Project does contain design and installation of a floating steel barge and wave attenuator system, these features will be performance-based specification.

The Project will include underwater construction for setting and connecting deadman anchors for the barge and wave attenuator.

The Project will include Structural Tests or Special Inspections related to the concrete slab-on-grade foundations for the UV Reactor and Generator foundation; concrete anchor blocks; geotechnical testing for installation of underground utilities, welding for work on the steel barge and wave attenuator. Additional special inspections may be reserved for the construction of the barge and wave attenuator.

The Project has multiple long lead items to include but not limited to; turbine pumps, UV Reactor, UV Enclosure, Generator, Wave Attenuator and Barge.

The Project includes a requirement to work with NV Energy for utility coordination. NV Energy will be providing design and installation of a new power transformer to replace the existing transformer located near campground loop D. The remaining power systems to the UV enclosure and barge will be the responsibility of the contractor.

The Project does contain demolition activities of existing electrical and piping equipment that may contain hazardous materials including asbestos cement pipe and a small volume of petroleum-based products and contamination.

The Project will require navigation warning buoys.

The Project does contain requirements of significant excavation for pipeline construction and near surface hard rock was encountered in geotechnical investigations.

The construction site is 30 of miles from nearest suppliers and lodging facilities.

The Park will remain open during construction, thus contract activities and logistics must be structured and scheduled to minimize visitor impact.

The site requires protective measures to ensure the surrounding area remains undisturbed.

The Project does contain some areas of cultural significance.

The anticipated period of performance of 580 calendar days including any potential weather shutdown.

Winter construction may be required. Although the climate has mild winters, extreme weather could impact construction schedule and construction efforts.

Project Scope:

This project will relocate and replace the Callville Bay water intake barge system to allow for drinking water production to a Lake Mead elevation of 950’ above sea level and negate further intermediate and costly barge movements. The current location of the water intake barge at Callville Bay can provide drinking water to a Lake Mead elevation of 1075’. Completing this barge relocation will involve the rerouting and extension of existing raw water transmission lines, construction of a moored breakwater, replacement of electrical transformer by a 3rd party power provider, replacement of existing standby generator with new appropriately positioned generator, as well as the extension and up-sizing of existing electrical lines. Enhance existing service road to access new system equipment (generator, UV treatment unit). Removal/demolition of existing barge, pumps and motors and associated controls and replacement with a new barge, pumps, controls system. Installation of a UV raw water treatment system to counter the Quagga mussel infestation of Lake Mead.

Proposal receipt date is not known currently. The actual date will be established in the solicitation documents.

A pre-proposal meeting may be posted, and date/location will be noted in the solicitation or a forthcoming amendment.
