Management of the preconstruction process for highway projects using manpower demand prediction models

The design of a comprehensive microcomputer-based system for managing pre-construction activities and programs in a State Department of Highways is described. Project-related activities from conception to award of a construction contract are researched and structured. Performance on a large sample of projects is analyzed, and models for predicting engineering manhours and durations are developed. Alternative models for estimating manpower demand across a long-term program are presented. The results are integrated in a modularized management system for planning and control of pre-construction projects and programs. This is the first identified formal investigation of the requirements for managing the pre-construction process. Managerial experience is captured and systematized. The trade-offs between organizational needs and project objectives are identified in the system design. Models for forecasting engineering performance are quantified. The results advance current knowledge of management of engineering activities.
