Abstract

This paper proposes a methodology for continuous schedule reduction in construction projects. Based on concepts and principles of Lean Construction the methodology considers actions on three stages to produce improvements and changes: (1) pre-construction, (2) execution, and (3) post-execution. The methodology suggests the application of several tools in accordance with specific needs (detected and desired) on several potential areas of improvement. The methodology was applied to the construction of Gas Stations with the following results in the implementation: reduction of 35% in schedule with respect to original company projects of the same type and 18% reduction with respect to the best schedule ever achieved in previous projects. These results were obtained in a very adverse environment for implementation, therefore, the potential reduction for future projects considers a schedule reduced 43% with respect to the best schedule result obtained during the implementation.
