Construction bid sites help contractors and subcontractors find projects they can bid on to gain more connections and get more work. These sites allow users to create custom searches, get alerts of new opportunities by email, and submit bids to the right decision-makers.

In a survey of 235 construction companies, 59% used software for running bids and 52% worked from a pre-approved list of contractors. What’s more, 18% of bidders said incomplete information about a project stopped them from making a bid. As a result, these contractors are missing out on winning new jobs and making it on those companies’ go-to vendor lists.

We looked at over a dozen construction bid sites for this review and chose the best based on the number of opportunities available, ease of use, bidding and tracking tools, price, and more. Here are our top picks.

What Are Construction Bid Sites?

Construction bid sites provide a list of construction projects needing contractors and subcontractors to help during pre-construction and construction. Because it can be very time-consuming to prepare a bid, these sites give users detailed information about each project so they can determine if it’s a fit for their business and worth bidding on.     

How Do Construction Bid Sites Work?

Construction bid sites make it easy for contractors and subcontractors to search for construction projects in the local area and in their field of expertise. Instead of spending hours or days sorting through local municipal or government sites for bid opportunities, users can search by keywords in the job description or project documents, location, or even the name of a company.

Construction bid sites also feature powerful contact tools that help bidders find the right decision-makers for each project. This ability to establish relationships with the right contact can place a bidder at the top of the list and help them win the job.

To help contractors and subcontractors find more opportunities faster, most construction bid sites let users set up daily email alerts about new projects and project updates and use advanced tags and filters to target only the jobs they want to bid on.   

How Much Do Construction Bid Sites Cost?

Many construction bid sites don’t publish fees on their websites to encourage vendors to contact them for custom pricing. Of the companies we reviewed, pricing ranged from $44 to $250 per month, with the higher prices reflecting more advanced search tools and access to more detailed project information.

How Do You Win Construction Bids?

Contractors and subcontractors are able to win bids if they can prove they are the best choice for the job. The detailed job descriptions offered on most good construction bid sites can help them find the perfect projects for their experience and skill so they can focus their attention on winning the bids that will get them more work and make them more money.

Because companies tend to use the same vendors over and over again for their projects, construction bid sites can also be a valuable tool to help contractors and subcontractors get their foot in the door to these companies.

How We Chose the Best Construction Bid Sites 

We looked at over a dozen construction bid sites for this review. While sites that offered a huge database of opportunities topped our list, we focused on those that offered customizable filters and tags to help vendors find the right opportunities.

It was also important to include sites that were easy to use. Because good bidding opportunities can disappear overnight, we made sure our providers let users sign up for daily email alerts with new opportunities and updates. 

Finally, although many of the sites we reviewed didn’t list their prices, we tried to avoid providers that charged exorbitant subscription fees while offering the same opportunities and tools as more affordable options. In the end, a good construction bid site should help vendors land regular projects from the same companies instead of having to constantly chase after new bids.
