Summary of Scope of Work:

This project will include fabrication and delivery of 12 structural steel turbine draft tube slot fillers. This includes 6 sets, with each set containing one north and one south draft tube slot filler. The sets are mirrors of each other and are very similar structurally. Each draft tube slot filler uses welded ASTM A572 grade 50 structural steel plates, ASTM A1085 Hollow Structural Sections (HSS) steel, and has small UHMW components. Each slot filler is a picture frame shape approximately 35 ft wide, 20 feet tall, and 3 ft deep. There are 20 ft tall legs made from rectangular HSS as the sides to the picture frame shape. Each slot filler will weigh approximately 35,000 pounds, mostly consisting of steel. The first slot filler set requires an Epoxy Polysiloxane paint system and the remaining 5 sets require 5-E-Z vinyl paint. One test slot filler set 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 5 sets.
