Our annual ranking of top construction firms highlights the top companies in Boulder based on their project volume over the past year, with a focus on relevance. This compilation is derived from permit and contractor information sourced from city, county, and state building departments through our partners at BuildZoom. For further information regarding data accuracy, please consult the note at the end of this article.
Construction data plays an increasingly important role across the construction industry, helping different groups make more informed and timely decisions. For businesses that supply materials or offer services to general contractors, tracking construction activity and milestones such as the start of major projects can help them know exactly when to reach out with relevant products or services. By analyzing contractor data and understanding construction market trends, these companies can identify which contractors are growing and may need support, allowing them to focus their efforts more effectively. Subcontractors also benefit by using construction analytics to find and connect with general contractors working on jobs that match their expertise. At the same time, developers, property owners, and project managers can use a contractor’s building construction history and permit records to assess reliability, performance, and licensing. Access to accurate construction market data helps all players stay ahead of trends in building construction and make confident, data-driven choices throughout a project’s lifecycle.
