Ext Generation of Construction Planning and Control System - the Lewis Approach

Eknarin Sriprasert¹ & Nashwan Danwood²

Abstract

The traditional construction planning and control system, as described in the Guide to the Project Management Body of Knowledge published by the Project Management Institute, has been criticized in terms of insufficiency of its underlying theories and ineffectiveness of its techniques. Based on this traditional approach, major problems including separation of execution from planning and after-the-fact variance detection are typically acknowledged. It is evident that the current practices are still suffering from low productivity and high production waste. To address these deficiencies, this paper proposes a vision for the next generation of construction planning and control as multi-constraints, visual, and lean-based system. An implementation of this vision has resulted in a prototype called “LEWIS – Lean Enterprise Web-based Information System for Construction”. An elaboration on the system framework and an underpinning methodology to integrate information and constraint management with 4D planning and control system is the focus of this paper. It is anticipated that successful implementation of this system will enable generation of reliable plans and constraint-free assignments to the work face, which in turn, reduce production wastes and improve on-site productivity.
