Field Estimating and Cost Control

The preparation of a preliminary outline, listing all data apt to be required, is a basic requirement for field estimating and cost control programs. Preparation of a formal classification of items of work should follow, considering adequate description division and proper indexing. Method of tabulation of indirect and overhead expense should be coordinated between various departments and projects. Periodic recapitulation of quantity and cost data can be keyed for efficient reference. Formal reports indicate independent courses of activity and are prepared at intervals to indicate trend. A labor productivity analysis will indicate variances between different projects and areas, based on a common standard. Recommended data for field estimates includes project records and reports, field manpower and equipment estimates, information from vendors and subcontractors, initial project estimate, data from previous projects, and handbook information. Application of field estimates includes construction alternates, analysis of extra work and revisions, and project cost estimates. A coordinated cost control program will assure adequate permanent property records and adequate information for productivity analysis, field estimating, and future estimating requirements.
