Engineering Sections at Jobsite (Inspection, Design and Drafting, Survey, and Facilities) and the Engineering Manager and his assistants were responsible for the interpretation of all H & N produced plans and specifications, If major revisions were required, a dispatch was sent to the Home Office Engineering Division requesting revised drawings or authority to redesign. If minor revisions were required, or if authority for major revisions were received from the Home Office, field sketches were prepared. FIELD SKETCHES AND CHANGE ORDERS Field sketches were prepared to augment Home Office drawings and to interpret changes and additional work authorized by the AEC Resident Engineer, A total of 575 of these were prepared at Jobsite. Additional work requiring expenditures exceeding $100.00 required the preparation of change orders. These were prepared by the Field Engineering Division and submitted through channels to the AEC, The change order indicated the scope, magnitude, and description of the work to be done, its estimated cost, and the justification, Upon approval by AEC, the orders were distributed to the construction departments. All departments of the Engineering Division contributed to the field designs necessary for preparation of change orders. However, the work of processing more than two hundred and fifty of these required the full-time services of an Assistant to the Engineering Manager for a period of several months during the fall of 1950. A detailed record of both field sketches and change orders was kept at Jobsite and was available for use at the Jobsite Engineering Office, INSPECTION AND MATERIALS TESTING The Inspection and Testing Section of the Engineering Department at the Jobsite was established on the basis of the philosophy which dictated that the organization should act as a continuous check on all construction activities to assure campliance with plans and specifica- tions. It was essential that the inspection be carried on in an un- biased manner and that the fact that the H & N organization was responsible for construction, as well as engineering, should not act as a limitation on inspection functions, In order to maximize the efficiency of inspection, Resident Inspectors were assigned to the various island locations at which construction work was being performed, and traveling inspectors specifically concerned with electrical activities, mechanical activities, paving, and concrete mixing circulated through the Atoll for the purpose of inspecting and noting progress in these specific fields of work, As warranted by work loads, Assistant Inspectors were assigned, Close collaboration was maintained between Inspection and Materials Testing personnel and, at the peak of operations, twenty four individuals were employed in these functions, 5-29
