Lean production theory, as a production
management tool, describes a system that delivers a finished product free
from defects, to a customer in zero time, and with nothing left in
inventory. Recently, the concepts of lean production have been introduced
to construction yet have generally been rejected. Lean construction
concepts were recently tested in a simulation environment and were found to
be effective. To facilitate the implementation of the concepts of lean
production in construction simulation, and subsequently within an actual
construction project, a generic approach has been created and is presented
in this paper. A special purpose simulation (SPS) template was developed
for surface works operations in road construction as an example
application. The template provides a means of testing the concepts of lean
production on road construction simulation models to quantify their impact
on road construction processes. This general approach for implementing lean
production theory was also proven to be able to direct the optimization
process of a construction simulation model in an appropriate direction.
