Suppliers of materials and services can effectively connect with general contractors by utilizing information about construction market trends and key project milestones. By keeping track of important events, such as the start of significant construction projects, these suppliers can time their communications to align with when contractors are seeking new resources, enhancing relevance and engagement. Additionally, by examining the growth patterns of contractors, material suppliers and service providers can better focus their outreach on those contractors poised for expansion.
