Revu from Bluebeam Software provides plumbing subcontractors with digital markup and measurement tools to perform accurate takeoffs and submit competitive estimates faster. Contractors can electronically redline drawings with industry-standard symbols, digitally sign documents and save custom markups in the tool chest for easy reuse. They can track and automatically group measurements in the markups list, or create a legend to identify and quantify each takeoff type directly on a PDF. Custom columns can be used to add formulas to the markups list to calculate material costs directly. 866/496-2140; www.bluebeam.com.
