Abstract:

After the first Last Planner System (LPS)  implementation in a Moroccan site, conducted by the authors Habchi et al.(2016) it has proven to be very difficult to implement the collaborative phase schedule, given the absence of collaborating companies (that joined the project later) and the availability of only one contractor (concrete contractor). In the other hand, most of the Moroccan construction projects are governed by design-bid-build contracts, where each lot is managed by a separate contractor, who has a direct contract with the owner. This leads to the fact that companies join the project at different intervals.  In this case, it is very hard to implement the phase schedule. In addition to that, the authors have noticed that there isn’t a direct link between WWP (Weekly Work Plan) and the Master Schedule in the Last Planner System. This paper aims to adapt the LPS model to remedy this situation so the new model can:

-Ensure the direct link between the Master Plan and Six Weeks Look Ahead schedule.

-Control project objectives all along the project by linking the Weekly Work Plan and the Master Schedule.
