and the inadequacy of the information derived from them, In July 1950, a new form was devised at the Home Office, and it was used from July 16, 1950 until the end of construction. This new form reduced the average length of the reports from 60 pages to 45 pages. Figures for completion percentages of construction work were ob- tained from physical checks in the field, from Daily Inspection Reports, and from other sources. Weights and percentage values of specific jobs were estimated from knowledge available as to the scope of the Contract, As more information was received concerning scope, changes were made, Major revisions to these basic figures were made in January 1950, July 1950, and March 1951, The Statistical Section furnished other regular and special reports and charts for Jobsite Management. Several special tasks were performed, such as conducting of manpower requirement survey in August 1950. In September 1950, the responsibility for Building and Facility Completion Reports was assigned the Statistical Section, Descriptions of property units were written, and quantities were ascertained and recorded for all buildings, facilities, and installed equipment, The reports were then forwarded to the Home Office for determination and recording of cost data, AS-BUILT DRAWINGS Inspectors were given copies of drawings of construction under their supervision, These drawings were to be marked to show all changes, and records were to be kept about changes which affected design or construction, No written procedure was promulgated for this work, but general instructions were that all necessary information should be included to make the inspector's copies as-built drawings. An As-Built Data Form was devised and put into use, but the procedure was burdensome to field personnel and compliance was imperfect. In May 1950, draftsmen were sent to the Jobsite to assist in making as-built drawings, but because design requirements were heavy these men could not start as-built work until late in 1950, In January 1951, several draftsmen were sent on temporary duty from the Home Office to assist in the work. The transparencies sent from the Home Office were used and information secured from field inspectors and engineers added to them. As buildings were declared completed and accepted, drawings for them were checked and revised. Completed and accepted drawings were signed by the Engineering Manager, and a copy attached to the Building and Facility Completion Report for transmittal to the Home Office. Completed transparencies were sent to the Home Office Engineering Office and two copies placed in the Jobsite engineering files. 5-34
