Explain and discuss the factors involved with cost control.
What will be an ideal response?
Cost control involves containing construction costs within the budget established by the cost estimate. Cost control is more than accurately reporting costs and comparing them to the estimate. It involves the use of the comparison to indicate a need to change methods, techniques, or crew composition to achieve the desired profit on the project. Cost and productivity control can help achieve additional profits on the construction project. Collection of actual construction costs for work activities also ensures an accurate cost database for the construction contractor. The use of accurate, proven construction costs can help with the accuracy of estimates.
