a. Large format {2-M^ x 2-1/4, 120, or 4 x 5) camera for 

 black and white photographs. 



b. Wide angle, normal (macro) and telephoto (macro) 

 lenses for above. Closeup capability is desired. 



c. Flash equipment or flood lamps for camera. 



d. Film for camera. Plus-X Panchromatic film preferred. 

 Amount of film required will vary from 50 to 250 

 exposures. 



2. Inspection and Miscellaneous Equipment and Supplies 



a. Flame cutting equipment and operators. This will 

 usually be available on site. 



VIII. Reporting of Results 



The final report should be either an informal report, technical 

 note, or technical report. The informal report can be prepared most 

 rapidly for limited distribution; the technical note or report require 

 more time for preparation but are published in a more polished form and 

 have a wider distribution. The preparation of a short informal report 

 followed by a detailed technical note or report should be considered. A 

 target date for completion of the draft of the preliminary report should 

 be 90 days from the completion of the recovery. 



The final report should contain a detailed description of the 

 damage incurred by the structure and a report of the results of the 

 laboratory analysis. Photographs should be included in the report. The 

 conclusions should include an assessment of the damage, its probable 

 cause, the expected lifetime of similar structures, and methods of 

 extending the lifetimes of similar structures. Unexpected corrosion 

 damage should be identified, and recommendations for further studies 

 should be made.
