Construction data plays a crucial role for many stakeholders in the industry. Material suppliers and service providers can use construction activity and construction trends to target general contractors more precisely. By tracking important project milestones, such as the start of new developments, they can approach contractors at the right time when resources are needed most. Additionally, analyzing contractors’ growth patterns allows these suppliers to focus on those who are expanding. Subcontractors can also take advantage of this data by reaching out to general contractors involved in projects they want to be a part of. For real estate developers, property owners, and others in need of contractors, using comprehensive building construction history allows them to validate the quality and expertise of contractors and subcontractors, ensuring they choose skilled professionals.
