TEST PROCEDURES SUPPORT EQUIBIENT AND FACILITIES At the time the tests were carried out, the New York World's Fair had been closed f o r about s i x months. Many exhi b i t s were t o r n down and others were i n various stages of demolition. Usual services such as telephones and e l e c t r i c a l power were no longer available at the s i t e . Thus i n preparing f o r the t e s t s , i t was necessary t o make special eurragements t o obtain these f a c i l i t i e s . E l e c t r i c a l power was brought t o the t e s t b u i l d i n g from a substation located about 1000 f t from the struct\are. Power was 3-phase 220V with 100 amp capacity. From the main block of outlets located inside the bu i l d i n g , extension cords were used t o d i s t r i b u t e the e l e c t r i c a l power used to operate the hydraulic pumps, the photographer's l i g h t i n g system, a general l i g h t i n g system, and certain recording instruments. Since most of the t e s t i n g was done during hours of darkness, 275-watt portable lamps with r e f l e c t o r shields were used i n the general l i g h t i n g system t o illuminate t e s t areas w i t h i n and outside of the building. The photographic l i g h t i n g system was composed of four 1000-watt photo- flood l i g h t s with r e f l e c t o r s . These were used f o r high i n t e n s i t y i l l u - mination of the t e s t area. Several 150-watt flood lamps were concen- tr a t e d i n areas where personnel operated equipment and recorded data. Instruments f o r recording strains and slab deflections were located on a mezzanine inside the building. V/hile the tests were i n progress, chairs, benches, and tables were available f o r use by personnel i n operating equip- ment and recording data. The hydraulic pumps and instrumentation f o r mea- suring load were located on the roof. Communication between personnel on the roof and on the mezzanine was maintained by radio receiver-transmitters. 2-3
