CHAPTER 5.4 FIELD ENGINEERING PROCEDURES The first Jobsite engineering service required by the Contract was to make all necessary topographical and other surveys and maps. Accordingly, the Chief of Surveys departed for the Jobsite with the first contingent of personnel, on February 1, 1949. The procedures by which the Survey Department accomplished the required work and the problems encountered and surmounted are described below in Chapter 5.8. The work included the establishment of a primary horizontal control network of twenty-three stations, with secondary control at each Project island, vertical control, topographic surveys and maps of sixteen islands, hydrography and location of submarine cable, location of special structures and instrumentation, construction staking, as-built surveys, and keeping of survey records and maps, Until March 1950, the Chief of Surveys served as the head of all Jobsite engineering activities. By that time, design and other engi- neering activities had become more significant parts of the work, and the Engineering Manager assumed control, The procedures formulated and followed by the field engineering organization were developed as the scope of the work at Jobsite increased, PRINTS RECEIVED AND DISTRIBUTED The Design and Drafting Department at Jobsite was responsible for the distribution of prints and for maintaining a file of current prints of drawings, organized for ready reference, Immediately upon receipt of the customary eight prints and one transparency of a drawing from the Home Office, the pertinent information concerning it was recorded in a card file or on a special index form. This task was simple, for the Home Office's letter of transmittal indicated the drawing title, number, and number of revisions. The same information was also used for check-out forms which served as the basic record for control of prints issued to various Jobsite departments, All prints issued were accompanied by a transmittal form showing drawing number, title, serial number, etc, When prints were revised, proper precautions were taken to insure the return of obsolete prints from the field and to remove them fram the field construction files. INTERPRETATION OF DRAWINGS It was inevitable that questions would arise concerning the proper interpretation of drawings because sometimes field conditions differed from those expected by the Home Office departments, and some- times changing priorities required in construction schedules allowed only a minimum of time for checking 5-28 at the Home Office, The
