When you outsource construction estimating, you’re not paying an idle estimating team. Instead of waiting for you to provide more projects for them to estimate, the construction estimating service simply goes on to its next customer’s projects, then gets back to your next set of projects when you provide them. You’re not paying estimators to simply sit around killing time without bringing in any profit; you’re paying them to work. Why keep idle estimators on the payroll with expensive benefits and taxes when you could instead pay a service that only charges you when they’re working?
