COLLAPSE OF TEXAS TOWER NO. 4 253 



Senator Saltonstall. In other words, you would believe that one 

 big wave would give a lot more stress than the small waves, as Mr. 

 Brewer testified ? 



Mr. RuTLEDGE. I am sure of it, sir. 



Senator Saltonstall. Now, one question where there seems to be 

 some considerable disagreement, if I recall the testimony correctly: 



Who designed the structure from the superstructure down ? It was 

 my understanding, and I stand subject to correction, that Mr. Ander- 

 son testified that ultimately they had nothing to do below the super- 

 vStructure, and that your firm designed all the legs and the support of 

 those legs including the subsurface foundation of those legs ; is that 

 correct ? 



Mr. RuTLEDGE. That's correct, sir. 



From the very beginning of this project, that was the situation. 



Senator Saltonstall. Referring to that model for a moment, from 

 the white part of the tower down, your firm had all the responsibility 

 for design ? 



Mr. RuTLEDGE. We also designed everything below the w^hite part 

 and the main structure members around the white part. 



Senator Saltonstall. I see. So that the Anderson firm designed the 

 electronics and the arrangements of the bunks and the facilities above 

 the platform ? 



Mr. RuTLEDGE. The structure contained a great deal of electrical, 

 mechanical equipment, large diesel generators, a great deal of wiring 

 to supply power to the radars. They had a large amount of electrical 

 mechanical work to do, and also they did all of the location of parti- 

 tions and this kind of thing inside the tower. 



Senator Saltonstall. Am I correct in understanding that there 

 was no previous construction of a tower at such depth of water, that 

 you know of ? 



sixty FEET MAXIMUM DEPTH OF ALL PREVIOUS TOWERS 



Mr. RuTLEDGE. That's correct, sir. When we made our studies in 

 1.954, the maximum depth we could find was 60 feet that anyone had 

 ever built a structure, and these were all in the Gulf of Mexico, where 

 conditions are much less severe than in the North Atlantic. 



Senator Saltonstall. And this was in 185 feet of water ? 



Mr. RuTLEDGE. This is 185 feet of water ; yes, sir. 



Senator Saltonstall. Did you have anything to do with supervis- 

 ing the actual construction after you created the design ? 



Mr. RuTLEDGE. Our responsibility was restricted to two items. We 

 were required to advise the officer in charge of construction at his 

 request. We were also required to have an engineer on the tower 

 while borings were made at the exact location to certify that the 

 ocean bottom materials were satisfactory for support of the tower. 



Senator Saltonstall. So that after you completed the design of the 

 legs, bracings and footings, you had no responsibility in supervising 

 construction ? 



Mr. RuTLEDGE. Except for these two items. 



Senator Saltonstall. Except for those two items, wliich were to 

 determine that the borings were satisfactory below the sand, and 

 what was the other one ?
