CHAPTER Ii, SECTION 1 Project Engineer for each of the laboratories, UCRL, LASL, DOD, Sandia, ABMA, and for the PAC construction program. Their function was to process all of the necessary engineering design and planning requirements of the Users from initial criteria through release of approved plans for construction use. The Project Engineers assigned in residence at laboratories and agencies acted in a liaison capacity to expedite new and changed criteria. During Operation HARDTACK,the Engi- neering Department provided design information to the Construction and Planning Department to enable that department to initiate procurement with as much lead-time as possible for satisfactory scheduling of shipping of critical materials and equipment to Jobsite.

Maximum use was made of repetitive designs, such as barracks, office and laboratory buildings, and structural barge features. The program as designed in the Home Office was under two broad classifications: namely, the Plant Acquisition and Construction (PAC) features of a generally permanent nature, and the Scientific or expendable construction. Civil, structural, mechanical, electrical, and communications designs were based on the best engineering practice consistent with the intended use. For example, a PAC building would be designed generally in accord with the Pacific Coast Uniform Building Code, whereas a camera observation structure intended for only one-time use would be designed to minimum standards for stability or weather resistance. Conversely, a PAC-type office for operating or maintenance activities would have only the ventilation necessary for personnel, while an expendable instrument shelter might be air-conditioned and de- humidified to ensure accuracy and protection of delicate scientific instruments. ¢ Home Office Jobsite 1640 699 384 449 2024 1148 Design The Home Office design program covered the 16-month period from September 1956 through January 1958, during which criteria were received, designs were completed, and construction drawings and specifications were issued to cover approximately $20,000,000 worth of scientific and support construction for the FY 1958 program. Some design work continued in the Home Office after 1 February 1958, but at that time all original drawings were sent to Job- site, and a design staff from the Home Office moved to the field to reinforce Jobsite engineering capability. The major features of HARDTACK involv- ed a vastly improved and highly specialized radio and telephone communications system, expansion of electric power and other utilities, unusual designs for four different typesof all-steel barges, major modifications and extensions to an airfield, including a unique type of sea wall, and highly specialized, air-conditioned buildings to house critical scientific equipment.
