Consistently participating in bids and submitting competitive proposals are crucial to a firm's long-term profitability and potential to win more construction projects. The process keeps the pipelines busy and ensures that there's enough cash to fund operations and pay the team for the whole year. 

Unfortunately, statistics show that general contractors only have an average of 6:1 bid-hit ratio, with some having as low as 35:1, making it difficult to grow a stable construction business. 

There are two solutions: 

  • Find the best bidding site to connect with the “right projects.” 
  • Complete accurate and competitive proposals in less time.

In this article, we’ll help you connect with the “right projects” by providing you with a selection of bid websites that are relevant for both government and private projects. If you’re looking for free bidding sites, some of the websites that I’ll mention below have a free basic subscription but can also be upgraded to paid subscriptions. 

By the end of this blog, we’ll also equip you with an AI estimating software that will streamline the bidding process by helping you complete takeoffs in seconds with 99% accuracy.

Government Projects vs. Private Projects: The Pros and Cons

There are two types of construction projects you can bid on: government projects and private projects. Each type offers advantages and disadvantages that you need to assess before investing time and effort in preparing your proposals. 

Government Construction Projects

These are construction projects under a formal contract with any government authority, such as the state. Government projects are required by the law to have open and competitive bids to avoid misuse of public funds and corruption.

Government Bidding Websites

To participate in government projects, construction firms can visit websites that list local, municipal, and state construction opportunities.

Here are the best bid sites for government construction projects:

General Services Administration (GSA) 

The General Services Administration (GSA) oversees federal properties and administers contracting options for government agencies. Over 130 federal governments are listed on the Federal Business Opportunities website. 

But to participate in all their design and construction contracting opportunities, first, you must register on for access to the drawings and specifications of the projects. 

System for Award Management or SAM

This site is intended for anyone interested in doing business with the government. They can use SAM to search for opportunities through:

  • Pre-solicitation Notices
  • Solicitation Notices
  • Award Notices
