Construction data plays a crucial role for various stakeholders in the industry. For businesses supplying materials and services, this data helps them connect effectively with general contractors by identifying important milestones and trends. By monitoring major construction activity, these suppliers can time their marketing efforts to align with contractors’ needs for new resources, which boosts engagement. Additionally, understanding contractor data allows material suppliers and service providers to focus on those who are experiencing growth. Subcontractors also benefit, as they can identify and reach out to general contractors for potential projects. On the other hand, real estate developers and property owners can use this data to assess the qualifications and expertise of contractors and subcontractors, ensuring they choose the right professionals for their projects.
