30 COLLAPSE OF TEXAS TOWER NO. 4 



by representatives of the 1st Naval District and Anderson-Nichols. 

 At this conference it was stated by Commander Albers of the 1st Naval 

 District that his recommendations were for the purpose of expediting 

 further caisson legs and main truss system to be assigned to Moran, 

 Proctor, Mueser & Rutledge and the deck which sits on top of the main 

 truss system to be assigned to Anderson-Nichols; thus each group 

 could carry out their part of a preliminary design and evaluation more 

 or less independently, though of course close liaison should be main- 

 tained throughout the evaluation period; Moran, Proctor, Mueser & 

 I^utledge to submit reports summarizing their studies of the various 

 types of tower structures and Anderson-Nichols to submit their report 

 covering the deck or platform on top of the main truss system ; these 

 reports to be submitted to the 1st Naval District in approximately 6 

 weeks or as much sooner as possible. He urged that Moran, Proctor, 

 Mueser & Rutledge reports be submitted in advance of Anderson- 

 Nichols' report in the hope that early approval of contract 2, the 

 detailed design contract, or design sections of the contract, might be 

 obtained. He also stated that the Navy would not pass on super- 

 structure, this being the function of the Air Force, and the Air Force 

 would not pass on foundation design. 



Division of Responsip.ilitt Between Architect Engineers 



Senator Stennis. Would you indicate on the tower model the sepa- 

 ration OT division of responsibility ? There was a definite separation of 

 responsibility. Please point out on the tower model the work 3' on were 

 to have and the work Moran & Proctor was to have. The top portion 

 of the model will come off. You can just take it off, if you wish. 



Mr. Anderson. Now, to describe the divisional responsibility, after 

 Commander Albers made this division, everything below the sea bot- 

 tom and everything above the sea bottom, including this entire leg 

 structure and the beam system, or truss system, as the expression has 

 been used, which goes around this platform into which the legs and 

 the connections for the legs are incorporated, is that part which 

 Moran, Proctor did. 



Senator Stennis. All right. Just lift the white top off of the 

 model. Now, does the remaining part represent what the Proctor firm 

 was to do ? 



Mr. Anderson. Not entirely. There is still incorporated in this 

 part of the s+^ructure some design for which Moran, Proctor was 

 responsible. They were to design the beam sections, or truss sections, 

 which go around the platform and up into which the legs would fit. 

 Our work at this point consisted of the architectural features involved 

 in the platform, such as the living quarters of the men, the partitions, 

 all mechanical work, which consisted of the power generating units, 

 the water system, everything of a mechanical nature and the electrical 

 system. We had to tie in with the Air Force as to the power require- 

 ments and that sort of thing. That was the part of the structure which 

 we were given at that point. 



Senator Symington. What percentage of the work was Anderson- 

 Nichols' and what percentage was the other company, roughly ? 



Mr. Anderson. Well, Senator, possibly the best way for expressing 

 that as far as the feasibility report is concerned is the amount of
