Problem Statement: You are a member of a nongovernmental not-for-profit agency doing relief work in Haiti ( Figure 1). When Haiti is struck by a hurricane, often an important bridge is destroyed by flooding. It has been destroyed five times in approximately the last 20 years. You are the project manager replacing the bridge. The bridge site is shown in Error! Reference source not found.. To make the new bridge more resistant to floods, your design team has noted that the roadway roughly parallels the River Pins as the road travels north of the bridge through an undeveloped area. They recommend contouring the riverbank to lower it to a height such that flood waters will crest the bank and flow through the undeveloped area, keeping the river level safely below the new bridge. Preparing the riverbank for this requires that a berm be created and that its elevation be carefully controlled so that flood waters will crest the entire berm at one time and so not cause erosion damage. When floodwaters flow into the undeveloped area they will encounter the roadway, so this requires installation of a series of culverts to the handle the volume of water and protect the road. Flood water then follows the natural ground contour back to the normal river course below the bridge. This will not endanger any structures.

2 Figure 1. Republic of Haiti. Figure 2. Bridge location (detail of yellow box). Task and resource information is provided in Table 1. Other important considerations: You have limited resources for your project. You have one road grader, one rough terrain forklift, one backhoe, and a survey team. Other resources are not constraining. Hurricanes are not a threat during your project. You can ignore weather concerns. The bridge spans and the box culverts are prefabricated and so they do not need construction time at your job site. They will need installation time. You will need to use the forklift for this step. Pouring and finishing the concrete will be done by a contractor and will not require any of your assets. After pouring, the concrete used for the roadway and the bridge supports must cure for at least seven days. Your team works a standard five-day, 40-hour work week. o Ignore how non-working weekends extends the seven-day minimum duration. (MS Project will assume the curing task makes no progress over the weekends, and that is OK.) Your start date is February 1, 2023. Table 1. Task Information.

See the course material section of the syllabus if you have not yet downloaded it. Set up the project in the software. Initially you should see a Gantt Chart with the project without resource constraints. Handling resources in Microsoft Project: o To resolve resource conflicts, click on Resource, then click on Level All. The Gantt Chart should now be adjusted to show the new date. You can click on Level Resource and select individual resources instead if that is desired. In this case you want to deconflict all the resources. o To return to the schedule with resources ignored, click Clear Leveling, select Entire Project, and click OK. o From the left most button (Gantt Chart in the Task ribbon or Team Planner in the Resource ribbon) click the down arrow to get the menu and select Resource Usage to see the daily resource allocations. Dont forget to set all the task modes to Auto Scheduled except for the start task which, should be set to 2/1/2023
