As a design build contractor you face several challenges. You face massive competitive pricing pressure in your markets. This competitive pricing pressure is squeezing your internal margins. Philosophically, as an experienced contractor you want to provide superior solutions (value added products and services) and win more bids but you must compete in a “LOW COST” mindset market.
