Our annual ranking of top construction firms highlights the top companies in Portland 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.

Construction data plays a crucial role in supporting various stakeholders across the industry. For example, businesses that supply materials or services to contractors can use construction market trends to better understand key milestones and trends in contractors’ operations. By monitoring important events like the start of new projects, suppliers can time their outreach effectively, ensuring they offer resources when contractors need them most. Additionally, analyzing contractor data helps suppliers target those experiencing expansion, increasing the relevance of their offers. Subcontractors can also use similar data to connect with general contractors they want to work with. Meanwhile, real estate developers, property owners, and others seeking contractors for their projects can use detailed construction analytics to assess the capabilities and reputation of contractors and subcontractors, helping them make informed decisions.
