What this contract is for

Agency: DEPT OF DEFENSE / DEPT OF THE ARMY
Location: SAINT LOUIS, MO
NAICS: 237990 - Other Heavy and Civil Engineering Construction
Scope: Federal

NESP LD25 1200 ft Lock --------- The new lock at Lock 25 will be constructed in the downstream direction in the auxiliary miter gate bay, which has minimum provisions for an adjacent 360-foot-long lock and is referred to as Location 3 in the System Feasibility Study (September 2004).

This contract will consist of construction of a new 1,200-foot drilled shaft-founded lock in the auxiliary miter gate bay, a 1,200-foot upstream ported guard wall, and a 650-foot downstream guard wall.

The existing 600-foot lock will remain in place and once the new lock is constructed and operational, will become an auxiliary lock chamber used primarily by recreation traffic or when the 1,200 ft lock is out of service. ------------ SEE ATTACHMENT FOR FULL DETAILS OF UPCOMING REQUIREMENT SOLICITATION. --------- Attachment 0004 Plans (Volume 1-7) and Attachment 0005 Navisworks Federated Model must be requested via email to Contract Specialist, Whitney Dee at [email protected].

Upon request they will be sent via DoD SAFE, since the files are too large to attach within PIEE or send via email. ------ SEE UPDATE LABELED 0817 FOR FULL DETAILS OF UPCOMING PRE-PROPOSAL SITE VISIT.

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
This listing has no set-aside restriction ("full and open competition"), meaning any business, large or small, can bid.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
