This solicitation announcement is for construction services for jetty and wingwall repairs in Kennebunk and Kennebunkport, Maine. The U.S. Army Corps of Engineers, New England District is seeking bids for repairs to the East and West Jetties and Wingwalls within the Kennebunk River Federal Navigation Project. Damages have resulted in an overall loss of stone structure protection and include loss of armor stone along both jetties and undermining of the east wingwall. The work will require both land-based and floating marine plant construction methods to address these damages. Approximately 110 linear feet of the west wingwall will be partially disassembled and re-built with existing fitted stones, and 80 additional linear feet along the jetties will require placement of new armor stone. The estimated value of the project is between $1,000,000 to $5,000,000 and the period of performance is 200 days. Bids must be submitted through the System for Award Management website.
