PRIMO Hub™ is a web-based construction collaboration platform developed by BRO Builder LLC. It allows General Contractors, subcontractors, suppliers, and other construction professionals to communicate, publish opportunities, discover qualified contractors, exchange proposals, verify business information, and manage professional relationships from a single platform.
Contractors can discover private commercial projects, private residential projects, government contracting opportunities, and Contractor Collaboration Opportunities—requests posted by contractors seeking additional labor, subcontractors, or specialty trades for projects they have already secured. Whether responding to bid invitations, recruiting specialty trades, or expanding a professional network, PRIMO provides a centralized environment designed specifically for the construction industry.
Not every construction opportunity begins with a bid solicitation. Many contractors have already secured projects but occasionally require additional labor, specialty trades, or subcontractors to complete specific scopes of work or meet project schedules. PRIMO allows contractors to publish these collaboration opportunities, helping them connect with qualified construction professionals without relinquishing control of the project or their relationship with the client. Rather than viewing every contractor as a competitor, the platform encourages professional collaboration by making it easier for construction companies to work together to deliver successful projects.

Behind PRIMO Hub is BRO Engine™, BRO Builder LLC's proprietary construction technology. BRO Engine powers the core functionality of PRIMO by collecting and organizing construction information from multiple sources, processing project documents, supporting proposal workflows, monitoring construction opportunities, and facilitating communication between construction professionals throughout the project lifecycle.
BRO Engine continuously processes construction data to improve the quality and accuracy of the information available within the platform. It also helps identify opportunities relevant to individual contractors based on their trades and business profiles, delivering real-time notifications through SMS and email while supporting procurement intelligence, contractor discovery, and other services throughout the PRIMO ecosystem.
