Now offering: Microsoft Excel spreadsheets for estimating structural steel erection and other steel related construction work activities. These Excel spreadsheets come with built in formulas for estimating structural steel erection, miscellaneous-steel work activities, steel decking and siding installation, rebar placement, pre-engineered building assembly and for pricing contract change orders. These linked take-off spreadsheets self-generate a bid proposal, a scope letter, a daily man/hrs log unique to each project and functions as an Earned Value Management System by calculating earned values and man/hrs earned. The estimator take-off work-sheets reflect work specific unit prices, work activity durations, man/hr and equipment cost totals and generate an accurate, easy to organize, schedule of values. When a project is bid and successfully contracted the BID take-off becomes the project management tool; an Earned Value Management System (EVMS). It is used for progress billing, for productivity comparisons, to compare scheduled durations with actual performance, and it is also used for impact claim documentation.
