Abstract

A database program called WorkPlan has been created to systematically develop weekly work plans. WorkPlan adopts the Last Planner methodology, which implements several lean construction techniques. A week prior to conducting work, WorkPlan guides the user step by step through the process of spelling out work packages, identifying constraints, checking constraint satisfaction, releasing work packages, and allocating resources; then at the end of the week, collecting field progress data and reasons for plan failure. This systematic approach helps the user create quality work plans and learn from understanding reasons for failure. The functionality of WorkPlan is detailed in this paper. Various ways of displaying work package data are illustrated. WorkPlan is to our knowledge the first computer tool designed specifically to implement lean production philosophy in construction.
