Master Builders of Iowa (MBI) has been a trusted leader in the Iowa construction industry since 1912, forging strong relationships with contractors, vendors, and design professionals statewide. As part of its history, MBI has also been a fixture in the project information arena since 1918 with the advent of a plan exchange. Over the better part of half a century, our operations evolved into a full plan room service. In 1986, MBI formally launched the Construction Update Plan Room Network, through which MBI operated up to 10 physical plan rooms, connecting more than 2,300 commercial construction firms and streamlining project bidding with innovative services focused on contractors and suppliers.
As technology changed the distribution of digitized plans and specifications in the late 1990s, MBI entered its next phase in project information services by partnering with Construction Software Technologies, Inc. (later ConstructConnect) in 2001 to introduce the iSqFt.com platform. For 17 years, MBI managed both physical and digital plan rooms, gradually transitioning its network online. In 2017, MBI closed its last physical location, focusing fully on digital solutions and strengthening its relationships within Iowa’s construction community.
MBI is now entering its next chapter in service to the Iowa commercial construction community with the offering of an entirely new project information platform called MBI Source1.
MBI Source1. is built for contractors by contractors. Through focus groups, one-on-one meetings, multiple contractor interviews and interactions, our Source1. team was able to develop a tool that is simple and efficient to use, while utilizing cutting edge AI functions that will help your team find more projects that align with your company's target market profile. All while keeping the subscription price very attractive as an MBI exclusive member benefit.
MBI Source1. will give MBI full control over development, pricing, customer service, and content, ensuring a locally focused approach. Leveraging its century-long reputation and deep industry relationships, MBI Source1 aims to deliver faster insights, cleaner data, and a more intuitive experience—empowering Iowa’s construction professionals to thrive in a competitive market.
