The document is a bill of materials for temporary pipe supports between turbine building columns. It lists 9 items needed including adjustable clevis hangers, nuts, threaded rod, and clamps to securely support 6" and 8" pipes lacking permanent supports in that location. An engineering evaluation found the pipes were suspended only by cables and needed additional supports to withstand the weight of the pipe, which is calculated in the report. The engineer recommends installing new supports as shown in the attached sketch.

FIELD ENGINEERING EVALUATION SI58 Page 1 of 1 Evaluator: Kevin Wilson Field Engineer Date: 8/24/11 Unit: 2 Building: Turbine Elevation: Floor El. 649 Location: Between Col. Rows D and H and Col. Rows T9 and T11 References: 1. 3BW0404-OO-01 - Mechanical Drains and Vents & Misc. Piping 2. 3BW0404-OO-42 - Mechanical Drains and Vents & Misc. Piping Problem Description: There is an 8 Pipe running from condenser at a location approx. 16 West of Col. Row E to the south and then parallel to Col Row T11 then thru a penetration in the floor to El. 629. The pipe has no permanent or temporary supports installed. There are only cables and turnbuckles installed. There is also a 6 pipe that runs parallel to the 8 pipe. The 6 pipe has some permanent supports installed, but it lacks about 3 of them. It is also suspended by cables. Evaluation Summary: The piping is 8 Sch. 120 which weighs 60.63 lbs./lin. ft. The 6 piping is assumed to be Sch. 120 as well and weighs 36.39 lbs/ lin. ft. The loads are calculated based on those assumptions. The loads calculated for each support are shown on SI58_Sketch_1. New supports should be installed as shown on the attached sketches.
