Create a Network Diagram from the above information 2. Develop a Pert Chart. To do this you must: - Determine the earliest start date for each task -Determine the latest start date for each task - Determine if there is any slack time - Determine the critical path and the minimum completion time 3. Ten weeks into the project, your contractor calls to say he under-estimated the work and it will now take three weeks for him to build in the new walls (increase the total worker hours which you did not plan for), unless they work overtime. Present a detailed analysis on the effect of this. You explain this effect to your supervisor with the following data: - It was previously going to take 2 persons working 8 hours a day to finish the new walls. You were paying them $15 per hour Your budget for them was $2400.00 (S1200.00 more than you needed). - 12-hour days are as much as they can work (Shours regular time and 4 overtime). - You analyze the overtime request, wondering if the contractor could use more help working 8 hours a day. Could this work and keep you on time and within budget? Present an analysis of the options. - Overtime is given at time and Ys or $22.50 per hour 4. You analyze the overtime request, wondering if the contractor could use more help working varying hours per day or varying number of days. Present a detailed analysis of not just the overtime, but the number of workers and numbers of days that would minimize the impact to your budget.
