Case summary: Major Design Corporation is a 3,500-employee firm with annual revenues of more than $1 billion. The firm offers full services and is divided into five geographically based global sales divisions. MDC was selected by the city of Saratoga to design a new, 10-million-gallon-per-day surface water intake and transmission main. This project is touted as an “alternative” water supply project because the water source is not a historically used source. The project will increase the long-term sustainability of the city because it will diversify the city’s water supply portfolio and recycle water. The project will also minimize the need for additional withdrawals from historic water sources, which have become less productive and more highly regulated in the past 10 years, as the city’s population continues to grow. Other green benefits of the project include reduced environmental impacts on the historic water sources and a reduced carbon footprint, as the irrigation water requires less energy-intensive treatment than the city’s other drinkable water sources.
MR J manages about six engineering projects at any one time, so the project is to be analyzed for ways to complete it in 35 weeks. The results are to be analyzed.
Interpretation: The way of modeling the uncertainties in activity times is to be determined.
