Our annual ranking of top construction firms highlights the top companies in Oakland 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 serves a variety of purposes for different players in the industry. Businesses that supply materials or services to contractors can use this data to better understand key milestones and business trends. By tracking important events like the start of major projects, suppliers can time their outreach to align with when contractors are likely to need new resources, making their communication more timely and relevant. Analyzing contractors’ business patterns also helps suppliers identify those experiencing growth, allowing them to target their outreach more effectively. Subcontractors, on the other hand, can use construction analytics to connect with general contractors they want to work with on upcoming projects. Additionally, real estate developers, property owners, and others who require contractors for projects can use construction market data to assess the quality and expertise of contractors and subcontractors, ensuring they choose the right professionals for the job.
