Sections 1 and 2 present a general discussion of Engineering and Con- involved with each item of work undertaken; Section 3 covers scientific stations; Section 4, SECTION | ENGINEERING DESIGN. On 4 March 1955, the Contractor was authorized to initiate the design of shot-island camps and to proceed with the design of scientific design and then submitted for estimates to the camps were to be simple, and as standard details for most of the expendable buildings to be The Engineering Order was used to disseminate criteria to the design staff; in addition the responsibility for the design of these camps was delegated to the Field Engineering Staff. This permitted the efforts of the Home Office the design de¥elopment and kept the Field Engineering Force informed of the work in progress. It also authorized work by the field stations in accordance with details furnished by UCRL, LASL, and DOD. As the shot-island used in shot-island camps had been prepared, Engineering Staff to be directed toward the design of complex structures, close liaison with the scientific agencies, and priority of design for scientific structures. To assist in expediting de- sign criteria for scientific facilities, the Contractor was authorized to station representatives at both LASL and UCRL. This proved effective Contractor’s Estimating Department and for construction authorization to the AEC Contract Representative in the H&N Home Office. it served as a record of changes made during forces which, because of its nature, was not defined on the drawings. All Engineering Order numbers were indicated on drawings for cross reference with the criteria received from the development at the scientific laboratories and Users. The Engineering Order was issued on receipt of initial criteria; then as additions and alterations were made, the Order was revised to reflect the changes along with the work already in process.

Criteria were generally received through letters and sketches, and in some cases preliminary information was received by phone. The letters and sketches were distributed to appropriate Project Engin- eers, who prepared rough draft Engineering Orders indicating the required design and drafting work. As soon as preliminary drawings were available, they were transmitted directly to the scientific agency involved for review and comments in order to effect agreement on the interpretation of the criteria furnished. This procedure was effective in establishing firm criteria as early as possible. As the User’s comments were received, drawings were developed to final the Stations were not firmed as early as had been anticipated. The lack of firm criteria in late September 1955, was the cause of concern as it appeared probable that completion dates could not be met. All possible expediting action was taken to speed design as soon as criteria were firmed and to permit procurement process- ing of long-delivery items. Where practical, preliminary drawings were released to permit the start of construction, for example, preliminary drawings were released for tower and guy anchor footings of the shot towers. By the end of 1955, a major portion of the criteria had been firmed and a number of drawings could be released to the field forces.
