The U.S. Army Corps of Engineers, New England District is issuing an Invitation for Bids for construction of a spur jetty that will be tied into the existing North Jetty located at the mouth of the Saco River at Camp Ellis Beach in the City of Saco, Maine. The NAICS code for this procurement is 237990 with a size standard of $45M. The estimated construction cost is between $10,000,000 and $25,000,000.The existing North Jetty at Camp Ellis Beach is an interlocked stone structure located at the entrance to the Saco River. Originally constructed in 1872, the structure has been lengthened and repaired numerous times over the years. The existing North Jetty is approximately 6,600 feet in length and constructed to a height of 15 feet MLW with an 8-ft crown width. Side slopes are 1H:1V. The proposed jetty spur will extend from the existing North Jetty into Saco Bay.The proposed work consists of constructing a 750-ft long spur jetty extending from the North Jetty into the Saco Bay at a location approximately 1500? from shore. As part of the spur jetty construction, the Contractor will reinforce an approximately 100-ft length of the North Jetty. The work includes mobilization and demobilization, the furnishment and delivery of stones, removal/rehandling/resetting of existing stones, and placement of new bedding, underlayer and armor stone for tie-in between the new and the existing structure. Anticipated stone required to construct the spur jetty and reinforce the existing north jetty includes approximately 9,500 square yards of 2-ft thick, stone-filled marine mattress; 13,000 tons of underlayer stone; and 38,000 tons of 8-12 ton armor stone (36,000 tons for the spur and 2,000 for the existing jetty reinforcement.) The reinforcement work will require substantial moving and rehandling of existing stones to obtain the required interlocking placement and construction tolerances. Construction, stone delivery, and access will be by water. Access to the breakwater by land is unavailable and no work should be completed from the crest of the breakwater. Environmental coordination and permitting is being completed by the U.S. Army of Engineers, New England District. Low tide water depths in the vicinity of the structure are approximately 10 feet, and the average tidal range is approximately 9 feet. The area is located 1500? off the shoreline and subject to wave action. No spudding or anchoring into the existing structure is permitted.Please note that this solicitation is unrestricted.
