Insights

Niche specialization RexConn Design focuses exclusively on structural steel connection design and uses a proprietary RexConn software, highlighting deep domain expertise that can be leveraged to upsell adjacent piping or coating coordination services within structural projects.

Regional licensure breadth With PE/SE licenses across many U.S. states and several Canadian provinces, there is potential to cross-sell to multi-state projects and position as a scalable, compliant partner for national and cross-border structural programs.

High project throughput Annual output exceeds 200 connection design projects, indicating strong capacity for handling bolted or welded connection scope on sizable commercial, university, and industrial buildings, which can be pitched for larger umbrella design-build or EPC opportunities.

Technology leverage Proprietary RexConn software paired with a documented review process suggests a defensible workflow advantage; sales can emphasize faster turnarounds, clearer calculations, and coordination across fabricators as differentiators in bids.

Growth through collaboration The firm’s experience with diverse fabricators and engineers signals a readiness to partner on integrated projects, offering opportunities to engage contractors, fabricators, and architectural/engineering teams seeking streamlined connection design integration.
