220 COLLAPSE OF TEXAS TOWER NO. 4 



solid structure, and the decision was that after, from the letter that 

 we have here evidently approving it, a decision was made not to 

 permit the welding and we, in turn, had to bolt this angle frame. 

 Senator Saltonstall. Now, there has been a great deal of dis- 



cussion- 



Senator Symington. Will the Senator yield? Will the Senator 

 ask who made that decision. 



Senator Saltonstall. Senator Symington asked who made that 

 decision. 



Mr. Rau. Well, this is a letter dated January 23, 1957, to the officer 

 in charge of construction, Texas towers, in Boston, and in this letter, 

 this was signed by our alternate project manager, a Mr. Ed Herb, and 

 he acknowledged receiving from Moran, Proctor, Mueser & Rutledge 

 of a drawing, of our drawing No. 47, revised such and such — all of 

 these drawings contain a notice of corrections which we considered 

 beyond the requirements of the contract, and then he goes on to say 

 down in the last paragraph : 



"On Continental Copper & Steel's drawings," which they had made 

 for us showing this holddown frame plan so and so, TT-4 template 

 bracing stowage elevation minus 73-6-4, several corrections were indi- 

 cated. "This CCS plan is based on S and M-K drawing 43 which 

 was approved by Moran, Proctor, Mueser & Rutledge." This was on 

 July 24, 1956. 



"The corrections indicated for the CCS plan modifies the S and 

 M-K drawing." 



It was, to answer your question. Senator, it was made by the archi- 

 tect engineer, Moran, Proctor, Mueser & Rutledge. 



Senator Saltonstall. I didn't hear that. 



Mr. Rau. The corrections were made by the architect engineer, 

 Moran, Proctor, Mueser & Rutledge. 



Senator Symington. The question that I asked was who was re- 

 sponsible for not making the corrections in accordance with the rec- 

 ommendation of the producer, and the answer is the people who in- 

 structed them to do it differently than they thought was the better way 

 of doing it, was the firm with the name ending in Rutledge. 



Senator Saltonstall. Thank you. It was a firm then and not the 

 Navy itself? 



Mr. Rau. No, sir. This letter though objecting was addressed to 

 the Navy, 



Senator Saltonstall. There had been a great deal of discussion here 

 about the relative merits of pins versus welds. Did you have any- 

 thing to do with making the decision as to whether there should be 

 pins on these braces or whether they should be welded ? 



Mr. Rau. We had nothing whatsoever to do with the original 

 design. Senator. 



Senator Saltonstall. So that your job was to carry out the de- 

 sign and construct the tower according to the designs that were given 

 to you? 



Mr, Rau. That is correct, sir. 



Senator Saltonstall. And you made no recommendations or sug- 

 gestions or anything else regarding those designs? 



Mr. Rau. No, sir ; we did not.
