Question 4: Linear Scheduling (Module 5): The curb for a 1,200 ft. service road will take 12 working days to construct. It will take 6 working days to build the first 600 ft., at which point a new access shaft will be built to an existing sewer system. The access shaft adjoins the curb on one side of the road, it will take 3 working days to construct, and is performed by the same crew that construct the curb. Once the sewer access shaft has been completed, the remaining 600 ft of curb will be constructed taking another 6 working days. Following the curb will be the construction of the sidewalk, which progresses at a rate of 1,200 ft. in 9 days, and must maintain a distance buffer of at least 200 ft. from curb and sewer access shaft construction. Following the sidewalk is paving of the road, which progresses at a rate of 100 ft. per day, and must have a 5 day buffer from sidewalk construction. Answer the following: 1. Neatly draw the linear schedule for this project (label all axes and lines). 2. Mark the critical path(s), including any tasks that are forced artificially to be critical. 3. In an attempt to reduce the project duration, it is decided to add a second crew for the task curb and sewer access shaft construction. They can start at any location along the length of the curb but only one crew can construct the access shaft. Decide on an optimal location and time for starting the second crew, and redraw the linear schedule. Mark the new critical path.
