This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. Backing Compound for Poe Lock Miter Blocks Part 1 GENERAL 1.1 Description of Need The Poe Lock at the Soo Area Office has three sets of miter gates that hold back t he water pressure generated by a 21 drop in water level from the upstream side of the lock to the downstream side. In order to achieve a proper seal between the gates, a set of steel miter contact blocks are used. Each gate leaf has a block extending the entire height of the gate on the edge that contacts the opposite gate leaf. Due to varying tolerances in the width of each gate leaf, these blocks must be adjusted accordingly. Adjustment comes in the form of jacking screws which hold the blocks up to 1 f rom the edge of the gate. After adjustments are made, this gap must be filled with a material to provide a leak proof barrier. Molten zinc was poured through 1 pour holes in the back side of the 60 high gate leaf to provide this barrier. Due to t he hazards imposed by the use of molten zinc, a better alternative was sought. Through research of products currently on the market, it was determined that a non-shrinking backing compound would be a suitable replacement for the zinc. However, the products researched all appeared to have a certain bonding strength to the materials that surround them. This being the case, a brushable release agent will also be required so that the backing compound does not bond with the surrounding steel surfaces. In additio n, there are gaps around the sides and bottom of the miter blocks. These gaps must be filled with some sort of packing to prevent the uncured compound from flowing out. Part 2 PRODUCTS & SERVICES 2.1 Materials 2.1.1 Backing Compou nd The contractor shall supply enough compound to fill 16,800 cu. in. The compound must be supplied in containers that allow approximately 1,400 cu. in. pours to be prepared at one time. A specification sheet for the compound shall be submitted as p art of the quote. The compound shall meet the following specifications: a. Pour viscosity no greater than 25,000 Cp at 35?F. b. Capable of curing to full mechanical properties within 5 days at 35?F. c. Working life no less than 20 minutes at 6 0?F. d. Capable of 1,400 cu. in. pours. e. Linear shrinkage no more than 0.0005 in./in. f. Pours will be in increments such that the filled void dimensions are: 10-1/8 wide X 1 deep X 120 high. After 5 hours curing at 35?F, the first pour must be capable of supporting a second pour above it. g. Water absorption must be less than 0.5%. h. Retention of physical properties at low temperatures down to -40?F. i. Compressive strength no less than 16,000 psi. j. Area occupancy within 4 hour s of pour without respirators. 2.1.2 Release Agent The contractor shall supply enough release agent to cover 36,000 sq. in. The release agent shall provide sufficient protection of steel surfaces by not allowing backing compound to bond to th ese surfaces. The release agent must able to be applied with a brush. It must also be capable of being applied to a vertical surface. The release agent must have a working life of no less than 7 days from date of application. 2.1.3 Packing Material< BR> The contractor shall supply 1,000 cu. in. packing material to seal gaps between gate and miter blocks. These gaps will range in size from 1/16 to 1 wide. Packing material shall supply sufficient bonding strength to steel surfaces in order to hold the pressure of uncured backing compound with minimal leakage. 2.2 Technical Support The contractor shall make available a technical representati ve for technical support during the pouring process. One trip shall be required to the Soo Area Office in Sault Ste. Marie, MI for a maximum of 5 days. The contractor will have 7 days advance notice of the need for a technical representative to be onsite. The tentative schedule for pouring would be from late February 2008 to mid March 2008. Part 3 DELIVERY 3.1 Delivery The backing compound, release agent, and packing material shall be delivered to the Soo Area Office, 119 Water St., Sau lt Ste. Marie, Michigan 49783. All materials shall be delivered with two copies of their respective MSDS.
