Y--Repairs to the South Jetty, Newburyport Harbor, Newburyport, MA

The U.S. Army Corps of Engineers will be issuing an Invitation for Bid for Repairs to the South Jetty. The proposed work consists of repairing the 1,400-foot-long jetty that was damaged during Tropical Storm Irene. Approximately 13,000 tons of armor stone will be required. 3-ton maximum stone size will be required for the first 1,000 feet, and 12-ton maximum stone size will be required for the most seaward 400 feet. Crest width is 5 feet for the first 450 feet, widening to 15 feet for the next 100 feet, and continuing at 15 feet for the remaining 850 feet. Crest elevation is +19 feet mean lower low water (mllw) at the most landward end, and lowering to +12 feet mllw at the most seaward end. Several hundred feet of the jetty are currently about 10 feet below the specified elevation - or at about +6 feet mllw. Side slopes are 1 vertical:1 horizontal on the river side and 2 horizontal:1 vertical on the ocean side. The work includes replacing displaced core and armor stone to fill in existing gaps in the jetty. Repairs will require substantial moving and rehandling of existing stones to obtain the required interlocking placement. Adjacent stones along the crest width should not exceed approximately 6 inches in elevation difference. About 6 days per month during the construction window seas can be expected to be in excess of 8 feet in the river mouth. Equipment and stone delivery and access to the jetty may be performed from land, water, or a combination. Protection of piping plovers and their habitat limits any work by land from September 1 to March 31. If access by land, the expected storage/staging area for the stone, equipment, and trailer is at the paved Newburyport parking lot, at the northern end of Northern Boulevard on Plum Island; access to the parking lot will be along Northern Boulevard in Newbury and Newburyport. It is about 2,600 feet from the parking lot to the jetty. It's expected that trucks will transport the stone from the parking lot to the jetty over mats over the vegetated dunes. Northern Boulevard, the parking lot, dunes, and any excess vegetation damaged will be restored to their pre-construction condition. About 5,200 feet of snow fencing will be installed along the access/haul route after construction, or by around March 31. The solicitation will be available on or about July 18, 2012 and will be available for downloading by accessing the Federal Business Opportunities website (http:/www.fbo.gov).
