. ties. The concrete wes poured easily through the templates to rough finish the concrete. After the concrete had its initial set, the templates were removed and the surface was finished. The front and back slope of the fill around these footings was stablized by putting on a ~“ layer of a 1 to 4 pretied grmut. After the timing station generator shelter had been constructed of I.Umberand corrugated metal, it was decided to use pyramidal tents for those at the 200 and 75 foot towers to save manpower and ~terial. Marston titting floors were provided in all these shelters. The causeway was constructed fxwm Biijiri toward Aomon and when the causewa,yreached the middle of the lagoon the southwesttip of Aomon began to erode. As the causeway approached Aomon, this erosion became increasingly serious to Gamma A and the last blast footing on Aomn. The Hawaiian @edging Company moored a barge parallel to and along side of tb west causeway wall shortly after th mid-point of the lagoon had been reached and this reduced the erosion. However, on 24 February higher tides and the shorter gap of about 75 feet produced cUrrentS in the.1.agoonwhich ticreased the erosion. On that day, the Hawaiian Dred@ng Company was requested to and did start a sheet pile jetty on Aomon. This sO-foot jetty, completed the next day, stopped the erosion. Work on the causeway tank road and curbs was started early in l&rch, but traffic and cable laying interfered, so night work became a necessity. To provide the fill behind the curb, additional sand was placed in the causeway and pushed over to the sides of the causeway with a grader and a dozer. The balance of the fill required was placed by clamshell. 29 Section XVI
