Z -- PAINTING OF THE SAGAMORE HIGHWAY BRIDGE, CAPE COD CANAL, BOURNE, MA SOL DACW33-98-B-0014 DUE 080498 POC Carol Husselbee, 978-318-8420 E-MAIL: Procurement Technician, Carol.K.Husselbee@usace.army.mil. The work of this project consists of blast clenaing and painting the entire steel superstructure of the Sagamore Bridge, including approach spans and appurtenances. Brush-off blast cleaning will be used as the overall cleaning method with commercial grade blast cleaning used selectively in heavily corroded areas. A cleaning survey will be performed to identify the heavily corroded paint failure areas. Less than 10 percent of the bridge surface will require commercial grade blast cleaning. An alkyd metal prime and intermediate coat, topped with an aluminum finish coat will be applied to bare metal surfaces exposed by the cleaning operation. Then, a finish coat of aluminum paint will be applied to the entire structure. The bridge is a continuous truss type structure coprised of apparoximately 5,000 tons of steel and is 1,408feet long and 51 feet wide. At midspan the lowest portion of the bridge structure is 135 feet above mean high water. The existing paint on the bridge includes red lead primer. Therefore, tight control over dust and lead emissions will be instituted during blast cleanng to minimize the impact on the environment. Level 2 containment per Steel Structures Painting Council Guide 6 (Con)(1995) is essentially full containment and will be accomplished in this project. Air monitoring will also be performed as a further safeguard. The estimated cost range is between $1,000,000.00 and $5,000,000.00. Work shall be completed within 420 calendar days after receipt of a Notice to Proceed. Plans and Specifications will be available on or about 6/30/98 at a cost of $30.00 per set. All responsible sources may submit a bid which will be considered by the New England District. (0159)
