Project Case Background: Simplex Construction LLC is a general contracting company. The company performs contracted work mainly in the area of engineering and heavy construction. The company executes multiple projects simultaneously at any given time and each project is managed by a project manager (YOU in this case as a project manager working there). Most contracts are awarded to your company on the xed cost basis contract and on \"design- bid-build\" basis procurement method. This means that projects executed by your company can only be protable by completing projects on time and Within budget with a heavy penalty on late completion. However, in construction projects, cost and/or schedule overruns could occur due to a variety of internal and/or external factors. These costs or schedule overruns can quickly wipe out prot margins and may result in a loss. Project losses generally are the result of problems of a few activities in a project which may impact other activities and hence, the entire project may be impacted negatively. It is not possible to avoid all schedule or cost overruns (like schedule overruns due to severe weather conditions), however, proper project monitoring can reduce the impact of these overruns. Recently your company has been awarded a contract by a mining company for building a community centre on a xed cost \"design-bid-build\" project.

Cumulative ? ? The Problem: The project was started as per plan. Working hours and days are 8 hours Monday to Friday. Work started at a slow pace in the first month with substantial delays in site clearances. In the middle of June, a severe labour shortage disrupted the construction site. Further, more than two weeks of work time was lost in June tasks due to the flooding of the site caused by the storm. By the mid of July, another problem surfaced related to the quality of work performed by a sub-contractor. The foundation sub-contractor failed to meet the standards set in the contract. About 20% of the work completed in July by this sub-contractor had to be redone. This resulted in delaying some of the activities, but the project manager and the team did not update the schedule and cost baselines. 4In Sep, the project manager realized that the sub-contractor was having problems in arranging safety equipment. A meeting with the subcontractor revealed that the subcontractor was having problems with nances. The project manager did not monitor the project performance and progress since the start of the project, and the project manager now is not yet sure of the problem. Currently, hiring a new contractor is not an option. The Client requested a status report from the contractor. A new project manager from the Client side took the place of the old project manager and rst thing he asked for is a status report from you for End of Oct.
