The City of Rockland is planning to build a new fire station. A project manager and the project team have been selected. The project team is interested in selecting a project scheduling technique that will be used to complete the project. The criteria for the process of selecting the project scheduling technique has been established as follows: easy to use, and shows the following – task durations, milestones, flow of work, sequence of events, which tasks can be undertaken at the same time, and how far tasks are from completion. The City Manager favors the Gantt chart, the Fire Chief likes Program Evaluation and Review Technique (PERT), and the project manager prefers the Critical Path Method (CPM). Assume you are the project manager; which project scheduling technique would you choose? Discuss the rationale for your decision.

Given problem: A contractor has a job which should be completed in 120 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 150 days. Of the 80 men, 50 are each paid Php 150.00 a day, 25 at Php 210.00, and 5 at Php 280.00. For each day beyond the original 120 days, the contractor has to pay Php 1,500.00 liquidated damages. How many more men should the contractor add so that he can complete the work on time? *Do show solution. Round off final answer in 2 decimal places. Thank you.
Use the following network and the data to perform the following: a) Prepare the manpower loaded Gantt chart with total floats of this project using early start and late times. Plot the manpower resource profile that shows the total number of laborers per day over the course of the project. Prepare the Gantt chart and the resource profile using the early start and finish dates of activities (not necessary to produce the late start and finish charts). b) Level the manpower resource given the constraint that the owner has only 14 workers to allocate to this project per day. Please try to do in excel. Thannks
