COLLAPSE OF TEXAS TOWER NO. 4 73 



Captain Albers. Those forces were considerably less than the maxi- 

 mum wave forces on the completed tower. 



Mr. Kendall. What was the reason for the elimination of the 

 pilings ? 



Captain Albers. It was done at the contractor's request. It was 

 considered, and we felt that the caissons sunk to the bottom are com- 

 pletely the equivalent of the piling that was originally planned. 



Mr. Kendall. How deep was the piling originally designed? 



Captain Albers. I would have to refresh my memory, sir. I have 

 forgotten. It was in excess of 20 feet. 



Mr. Kendall. Didn't you make a statement just a while ago as to 

 the depth of the pilings ? 



Captain Albers. No, sir, the caissons go down 20 feet. 



Senator Jackson. He was talking about the overall depth. 



Mr. Kendall. The caissons in this tower are imbedded only 20 feet? 



Captain Albers. That is right. 



embedment of legs of TO'WERS 



Mr. Kendall. What is the embedment of Texas towers Nos. 2 

 and 3? 



Captain Albers. Texas tower No. 3 is 60 feet ; Texas tower No. 2 is 

 considerably more; less in diameter. I may have those figures here. 



Texas tower No. 2 was 63 feet, sir. 



Mr. Kendall. Was that the piling, or just the embedment ? 



Captain Albers. Just the embedment of the caissons. 



Senator Jackson. And what was it for tower No. 4 ? 



Captain Albers. Twenty feet. 



Senator Jackson. May I just ask this question ? 



What kind of soil in each ? 



Captain Albers. All three of them were compact sand ; sand with 

 some ground. 



Mr. Kendall. Actually, as built, Senator, the embedment of Texas 

 tower No. 4 was only 18 feet, I believe. 



Well, will one of you other gentlemen be looking, if you have the 

 information, to find out specifications for the piling as originally 

 designed ? 



Mr. Edwards. We do not have it here, sir. 



Senator Jackson. Might I ask this question? 



Senator Stennis. Certainly. 



Senator Jackson. Was the ocean soil the same at all three sites? 



Captain Albers. Substantially the same at all three sites. 



Senator Jackson. I understood there were some differences. I just 

 raise this question, that at site No. 4, it was more silt and less the firm 

 type of sea soil than was involved in No. 2 and No. 3. 



Captain Albers. It is my understanding, Senator Jackson, that it 

 was very hard sand in all three of these sites. The other two towers 

 which were not completed did have a different appearance. One was 

 solid rock, and one was loose boulders. 



Senator Jackson. What is the reason — go ahead. 



Senator Stennis. The question comes to my mind. Why put this one 

 20 feet and the others less ?
