Abstract

Material waste has been an important issue to be addressed in order to reduce environmental impacts of the building construction activities. The extra mass of materials expended (Souza et al., 1999 [8]) can be as large as 25% of the amount prescribed by the design. In this context, Brazilian construction companies have been trying to implement actions aiming to improve materials management. This paper describes a case study where the authors coordinated an experience, in a building construction site in São Paulo, where a new management approach was adopted. Based on an extensive database, collected from more than one hundred construction sites, weekly meetings were held, gathering together site and subcontractor managers, in order to evaluate the previous week’s job performance, to define actions to be implemented to improve the job process, and to define goals to be achieved in the next week. Due to the objective tools used, the main contractor and the subcontractor were induced to act as partners, and the detected material waste index was smaller than the minimum value of the available database. This paper describes this experience (the method adopted, information and decisions related to every week meeting) concerning the target of reducing concrete blocks waste.
