H. MORRISS April 10, 1967 ASST. CHIEF OF CON STRUCT I ON Mr. Ray A. Nixon Chief of Construction City Hall Atlanta, Georgia Subject: 1~ / I Proposed Covering for Atlanta Stadium Dear Mr. Nixon: You asked for my comments on the proposed air-supported covering on the Atlanta Stadium, and I would think that the following information would be necessary before one could fairly judge the above structure: 1. The material used and the life expectancy. 2. The noise of the inflating equipment. 3. The number of men that it takes to erect and take down the covering, as they would have to be trained people on a regular payroll in order to function efficiently. 4. For an ingress and egress for a large number of people the method of controlling the pressure for keeping the dome supported. I am afraid this is not of much help, but I believe the information would be necessary before one could make a recommendation. Yours truly, R. G. Aaron Engineer of Bridges RGA: jb ATLANTA Tl-IE DOGWOOD CITY �
