THIS IS NOT A REQUEST FOR PROPOSALS, QUOTATIONS, OR BIDS, NOR A SYNOPSIS OF A PROPOSED CONTRACT ACTION UNDER FAR SUBPART 5.2. The proposed action will be a construction project with a firm-fixed price contract. The type of solicitation to be issued will depend upon information received in response to this sources sought announcement.

No reimbursement will be made for any costs associated with providing information in response to this sources sought announcement or any follow-up information. We anticipate this to be evaluated as Low Price, Technically Acceptable (LPTA). Responses to this sources sought announcement will be used by the Government to make appropriate acquisition decisions. NO SOLICITATION IS CURRENTLY AVAILABLE.

This is not a request to be placed on a solicitation mailing list and is not to be construed as a commitment by the Government. The results of this survey will be considered to be in effect for a period of one year from the date of this notice.

The purpose of this sources sought announcement is to gain knowledge of potentially qualified Small Business, 8(a), Woman Owned Small Business, Service-Disabled Veteran Owned Small Business, and HUBZone contractor sources; as well as their size classifications relative to the NAICS code 237990 – Other Heavy and Civil Engineering Construction, PSC code Y1PZ-Construction of Other Non-Building Facilities, and Small Business Size Standard $45 Million.

Depending upon the responses associated with the business categories listed above, the solicitation will either be set aside in one of those categories or be issued as unrestricted and open to both small and large businesses. After review of the responses to this announcement and if the Government still plans to proceed with this project; a separate solicitation announcement will be published on SAM.gov (www.SAM.gov). Responses to this announcement are not an adequate response to any future solicitation announcement.

BACKGROUND: Mud Mountain Dam is a zoned earth and rockfill structure with an 810-foot-long crest and a maximum height of 432 feet above bedrock. The structural height of 427 feet is measured from the bottom of a structural depression located approximately 170 feet upstream of the cutoff wall to the new top of dam at 1,257 feet NGVD29. The dam is 1,600 feet wide at the base, 25.5 feet wide at the crest, with a design crest elevation of 1,257 feet NGVD29.

A concrete seepage cutoff wall extends from the crest into bedrock in the core of the dam. Mud Mountain Dam is constructed in a narrow canyon where rock walls on both sides of the gorge rise almost vertically to a height of nearly 275 feet above the White River channel. The upstream hillside slope at the left abutment is steep (approximately1:1).

Lower Cascade Creek (LCC) drains into an existing Water Control System (WCS) consisting of debris screens, a concrete lined catch basin and pipes which convey flow along the upstream left groin to the pool. The upstream groin is armored with shotcrete to approximate EL 1167.8 feet (NAVD88). The catch basin and embankment abutment tie-in are separated by roughly 51 feet of sandy-gravel fill between EL 1,267.8 feet (NAVD88) (basin) and 1,264.3 feet (NAVD88) (crest).

The current WCS was not designed to a handle a specific flow or event with a defined return interval, because there is very little available hydrologic data on flow-frequency for LCC. Rather, the existing inlet basin was constructed to address recurring erosion caused by flows from past events along the upstream groin. This lack of a specific design event or flow has led to failure to control flows at the inlet even without debris accumulation.

The LCC watershed is approximately 0.4 square miles or 0.1 percent of the Mud Mountain Dam watershed. Additionally, the watershed for LCC is immediately adjacent to the dam making it very likely that a large precipitation event would load both watersheds as it moves across the region. Due to the size and nature of the watershed, peak flows on LCC occur sooner and have a shorter duration than those observed on the White River. Consequently, high flows occur on LCC before much of the precipitation in the White River basin concentrates and begins to raise the reservoir.

CONSTRUCTION REQUIRED: The purpose of this project is to replace an outdated and inefficient water control structure incapable of containing high water volumes from LCC. In 2009, a flood event overtopped the water control structure, and uncontrolled creek flows eroded both the upstream and downstream left groin of the dam causing extended disruption to project operations.

MAGNITUDE OF CONSTRUCATION: In accordance with DFARS 236.204(ii) “Disclosure of the Magnitude of Construction Projects,” Magnitude of Construction is estimated to be between $10,000,000 and $25,000,000.
