COLLAPSE OF TEXAS TOWER NO. 4 211 



saying that the greatest motions we observed, measured, were plus 

 or minus 3 inches. 



Senator Stennis. That means 3 inches one way and 3 inches the 

 other way ? 



Mr. Brewer. Yes. For that range there was no evidence that the 

 underwater bracing was helping at all, helping this structure. 



Senator Steistn-js. Well, my impression is that this is the most re- 

 vealing testimony on this point that we have had. . 



Senator Saltoi^tstall. Would the Senator yield ? 



Senator Stennis. Yes. 



Senator Saltonstall. Would I understand, just to make it clear to 

 a layman's mind, that because of this 3-inch motion above the water 

 you came to the conclusion that the braces under the water within 

 those 3 inches were not effective at all ? 



Mr. Brewer. That is correct. 



Senator Saltonstall. Did the bracing become effective if the mo- 

 tion was greater than 3 inches ? 



Mr. Brewer. Well, they could be. You see, we have no way of 

 knowing, because 3 inches is the greatest the tower ever moved that 

 winter. 



Senator Saltonstall. I see. 



Then the most motion that you detected above water was the o-inch 

 motion ? 



Mr. Brewer. That is correct. 



Senator Saltonstall. And that 3-inch motion was something which 

 proved to you that the underwater bracing was not doing its job ? 



Mr. Brewer. That it wasn't doing anything over that range; we 

 knew that. 



Senator Saltonstall. Yes. Thank you. 



Senator Stennis. All right. Thank you again, gentlemen. Thank 

 you very much for your testimony. 



We have as the next witness Mr. E. G. Ran, who was the chief engi- 

 neer for the contractor who had the responsibility for the construction 

 of this tower. 



;Mr. Ran, will you come around, please, as soon as these gentlemen 

 have left the table. 



All right. 



Mr. Rau, you understand that it is the unbroken custom of this 

 committee to have witnesses sworn. 



Do you solemnly swear tha,t your testimony here at this hearing will 

 be the truth, the whole truth, and nothing but the truth, so help you 

 God? 



Mr. Rau. I do. 



Senator Stennis. Are these gentlemen who are with you going to 

 testify ? 



Mr. PiLZ. No. Mr. J. Rich Steers is on the right side, and I am the 

 counsel. 



Senator Stennis. You may advise the witness of course. Mr. Rau, 

 Ave are glad to have you here, sir. We have had other testimony about 

 this matter, and we always like to have the gentleman here who did 

 the actual work and construction. 



Mr. Rau. Thank you. Senator.
