CHAPTER II, SECTION 3 These stations were reinforced concrete collimating baffles 15° wide and 2’-6” thick with heights determined by the required elevations at the top of the baffles. The elevations ranged from plus 18.0 feet for Station 2260.06 to plus 28.86 feet for Station 2260.01. The working points of the baffles were required to be at the center line and on the nearest face of Station 22. Station 2260.01 had two holes and the remaining stations had one hole. Forms for these stations were prefabricated at Nan. The footing excavations for Stations 2260.05 and 2260.06 contained as much as 18” of water at high tide. In pouring these footings, the pour was started in one corner and continued progressively across the footing, thus forcing the water ahead of the concrete.

A buttress was placed behind each structure to enable it to Figure 2-105. Station 2251.02 furnished the lead collimating discs and stands. The disc for Station 2251.01 was 64” in diameter, 6” thick, and contained a 64” diameter hole in the center. The disc for Station 2251.02 was 42” in diameter, 6” thick, and contained a 6%” diameter hole in the center. Twelve cubic yards of concrete were used.
