The Contractor was required to These stations consisted of User-furnished and Contractor-installed steel instrument shelters. They were approximately 9’ x 6’x 6’ high and contained a vertical hatchway. Each shelter was buried under about 10 feet of earth. A 10’high pipe mast used to support reflectors was mounting the specimen for Station 591.01; the The mast was eliminated at Station 810.02; this station was used with a mirror known as Station create a safety hazard along theairstrip. Each station was fitted with a one-inch triangular-shaped steel plate to match the top suspend a two-ton User-furnished specimen between. these plates. The rigging broke while specimen fell striking guys and a tower causing the collapse of both towers. Due to the limited time available, a new method of hanging the specimen was designed in the field. This method consisted of two 6” pipes, 30 feet long, mounted V-shaped, and welded on a bracket to one of the Station 6 tower legs. Each pipe end of the Page 2-76 installed at each of Stations 810.01 and 810.03. 812.01 which was mounted at the 37 14-foot level of Station 1515. Power was supplied by Userfurnished batteries. Timing signals of minus 15 seconds, minus 5 seconds, and minus 24% seconds were required at Station 810.01, and minus 15 seconds, minus 5 seconds, and minus 1 second were provided at Stations 810.02 and 810.03.
