From your network of contractors, you hear about a great construction project requesting bids that your firm would be perfect for. You read the RFP and spend days creating a detailed and accurate estimate. But then you find out that the lead is old and there is simply no way your firm can beat out the competition. So you’ve wasted time and labor and are no closer to finding work. This is all too common in an increasingly competitive bidding environment in which the average margins for the construction industry are less than 1% and most firms are losing more bids than they are winning. 

Gaining referrals through partnering architects and engineers and word-of-mouth through previous clients are some of the best ways contractors can find the right projects. And in an ideal world, contractors no longer have to bid competitively on jobs, because clients are actively seeking them out. But in reality, most contractors don’t have established reputations or networks and struggle to find new work. However, there is a solution that enables builders not only to find more jobs to bid on, but also the right jobs: construction bidding websites. When construction bidding websites were first launched, they had few opportunities and charged a fortune. However, in the last few years, construction bidding sites have come into their own--offering more variety and pricing options--becoming the go-to resource for contractors to find jobs and win more bids.

Indeed, the best construction bidding websites provide information about construction projects as well as contact information for the client. Each website also provides a unique interface and bidding package. A major benefit of construction bidding websites is that you can perform searches for the right project based on your construction company's specialties and preferences. You can also view projects in various locations across the country and around the world. By having this information at your fingertips, you can leverage a cost estimating service and the definitive guide on how to master the bidding process to create the right bid to submit for your ideal project.
