Summary of Scope of Work:

This project will include fabrication and delivery of 12 structural steel turbine draft tube slot fillers. This includes 6 pairs, with each pair containing one north and one south draft tube slot filler. Each draft tube slot filler uses welded A572 grade 50 structural steel plates, A500 grade C Hollow Structural Sections (HSS) steel, concrete (used solely for ballast), and has UHMW components. Each slot filler will be approximately 35 ft wide and 3 ft deep. There are 21 ft tall legs made from rectangular HSS on each end of the slot filler for it to stand on. Each slot filler will weigh approximately 55,000 pounds (25,000 pounds steel, 29,000 pounds concrete, 1,000 pounds UHMW). The steel requires 5-E-Z vinyl paint as the structure will live underwater. One test slot filler set (one north and one south) will be delivered first. The test set will be installed, inspected, and tested by McNary project personal. If any design changes are needed, they will take place at this time. Once the test set is tested and any design changes are completed, the Contractor will be released to fabricate and deliver the remaining 10.
