Construction data serves various purposes for different players in the industry. For example, businesses that supply materials and services to general contractors can use this data to target their audience more effectively. By monitoring key milestones, such as the start of large construction projects, these companies can time their outreach to match when contractors are most likely to need new resources. This ensures their communication is both relevant and timely. Additionally, by examining contractor data and business activity patterns, suppliers can identify contractors who are on a growth trajectory and may need additional support. Subcontractors can also use this data to approach general contractors they want to work with. On the other hand, real estate developers, property owners, and others who need contractors for their projects can use the data to verify the skills and experience of potential contractors and subcontractors. By analyzing construction industry trends, they can ensure they are selecting professionals with the right expertise for the job.
