This paper describes the work conducted to improve productivity during the construction of a Shopping Centre in South America. The work was based on: detailed “design” of construction methods, including the equipment, optimum crew, work procedures, and; detailed production planning, generated in weekly and daily basis. The construction job was particularly complicated due to the hundreds of change orders demanded by the owner and the owner’s clients. The construction followed a fast track scheme, and the contractor was forced to accept last minute changes which generated all sort of delays and work peaks. As in many countries, the actual construction depends mainly on the foremen and crew leaders. The work presented in this paper empowers the construction field engineer, allowing him to plan, control and optimize on-site construction performance. Despite the many project change orders and the resistance of foremen to change, after 10 weeks the productivity of the job was increased two fold. Numerical results, as well as the methodology applied for this study are discussed in this paper.
