Construction data is a crucial tool for a wide range of professionals in the construction sector, helping them navigate and succeed in a competitive market. Companies that supply materials or services to general contractors can use construction analytics and insights into construction trends to identify significant moments, like the launch of major projects. By doing so, they can time their outreach to when contractors are most likely to need new resources, improving their chances of engagement. Subcontractors can also benefit by targeting general contractors based on construction market data, focusing on those with active or upcoming projects. Meanwhile, property developers, real estate investors, and others who rely on contractors can assess their qualifications and expertise by examining building construction history and ensuring compliance with relevant contractor licenses and general contractor permits. Using these insights, all stakeholders can adapt to trends in building construction and enhance their strategies effectively.
