The USACE-Chicago District is conducting a market survey to identify firms capable of performing marine construction for the Kewaunee Harbor Breakwater Section C Repair project in Kewaunee, Wisconsin. The work involves replacing a 60-foot breakwater retaining wall with a combi-pile system, including bedrock anchoring, all performed from a floating plant within a confined 17-foot-wide area. The estimated cost magnitude is between $1,000,000 and $5,000,000, and the applicable NAICS code is 237990 with a $37.0 million size standard. Interested small businesses, including HUBZone, 8(a), WOSB, and SDVOSB firms, must submit documentation of bonding limits, up to three similar marine construction projects, and details on meeting the 40% dredging volume requirement. Responses are due via email to the specified contact, with the subject line including the notice title.
