Scheduling using MS Project 2007;
Current editions of MS Office Professional edition contain MS Project 2007.

Quantity Take-Off;
We will be using full size drawing, for the take-off section including; cut and fill calculations, stormwater management and environmental remediation.

Construction Cost Estimating;
Information from the quantity take-off will be used for construction cost estimating using "National Construction Estimator 2007 from Craftsman"

Project Cash Flow;
Data from the cost estimating program with overhead and profit factors will be used with the Schedule to inform cash flow, line of credit, gross profit and net profit.

Review impact of project delay from; owner, arch/eng, GC, regulatory, weather, industrial action,....

Review impact of project change order on cash flow and overhead and profit.
