The monthly volumeoftraffic handled by the Home Office teletype room in- creased steadily from 2000 messages in April 1957 to a peak of 4085 in January 1958. SECTION 3 ESTIMATING Cost estimating and related work were performed by two Project Estimating Groups, one located at the Home Office and the other at EPG, The Home Office Group, directly responsible to the Manager, Construction and Facilities, worked under the supervision of the Project Chief Estimator for AEC activities. The Jobsite Group functioned as part of the Jobsite Engineering Division under the control of the Resi- dent Engineer. Basically, the Home Office Group prepared estimates for work designed in the Home Office, and the Jobsite Group prepared estimates for work designed at Jobsite. SEQUENCE closer the estimates were to the actual costs. Because original criteria were usually incomplete and subject to change, a series of estimates was prepared starting with original criteria and progressing to final criteria. The various types of Construction Cost Estimates referred to in the table below indicate the sequence in which they were prepared and also the type of criteria upon which the estimates were based.
