After the sand was in place, it was decided that an area of 100,000 sq. ft. around Gamma Stations A & B should be stabilized, using the soil cement method in an attempt to control the dust that would rise after the blast. Outside power @#stritutien wires were placed around the timing station, Gamma Station B and blast building, Monday, 8 March, under the direction of GHEE and lh of AEC. This proved to be a very simple task as care was taken to label each wire as it was placed. All other outside wiring and floodlight installations were finished during the week ending 13 March. Most of the week ending 20 March was spent removing excess supplies from three 40 ft x 100 ft Quonset huts on the North end of the island near the Zero Tower, and in general police and clean up around all structur’s.-Aléo during this week a 38 ft square concrete slab 4 inches thick was poured underneath the Zero Tower. This was the last concrete to be poured for any AEC structure and all work up to this time was one week ahead of schedule. However, there still remained four concrete bases to be poured for seismograph instruments; two located on this island and two to be precast for Parry Island. This work was finished during the next week and QM of the U.S. Coast and Geodetic Survey who arrived 24 March began installation of the seismograph equipment. The seismograph installations were com- pleted on 31 Marth. Section VIb 70 PRIVACY ACT MATERIAL REMOVED
