RSA says its On-Screen Takeoff (OST) solution can streamline the takeoff process by completing measurements and calculations as takeoffs are drawn right onto the screen. OST connects takeoff data to engineering systems, estimating platforms, spread sheet solutions, and the RSA Calculations Solutions, automatically saving takeoff calculations for quick access. The company says OST reduces errors and missed takeoff with a visual audit trail of the quantity takeoff. Quantities are instantly available for length, surface area, volume and count, eliminating errors and labor time spent on manual calculations. It also features an optional Estimator spreadsheet to quickly complete bids.
