If you were asked to perform an excavation contract competitivelywith limited boring data, what type of contract would you want and why?

The contractor implements last planner on the project. During week 1, the following tasks are planned and committed by different subcontractors. At the end of week 1, the status of the tasks is also shown in the following table. What is the percent plan complete (PPC) for week 1? Explain what PPC measures?     Committed on Completion Progress Completion? Mobilize Yes 100% Yes Install Security Fence Yes 100% Yes Set Forms Yes 80% No Excavate Planter Foundation Yes 100% Yes Construct Masonry Planter Yes 50% No

Given the excavator information below, calculate 1) Hours required to complete 1000 CY of excavation work. 2) Cost of the operator to complete the work if his hourly wage is $35. Production Information Bucket Cycle of Operation Efficiency 3 cubic yard (CY) 40 second per cycle 45 mins per hour

1. Explain in detail the effect on project indirect costs when a job is lengthened and when it is shortened. 2. In any given construction scenario a limited number of days can be taken out of the schedule before it becomes impractical to try to shorten the schedule further. Though it is impractical to take the exercise to the theoretical limit of shortening, there is a theoretical limit that prevents any further shortening of the project. What defines this theoretical limit, and what conditions exist in the schedule when this limit is reached?
