Integrating MEP Systems in Structural Steel

For lead consultants and construction management firms, the seamless integration of Mechanical, Electrical, and Plumbing (MEP) systems is a critical project milestone. In structural steel and PEB construction, early coordination between the structural engineer and the MEP consultant prevents costly on-site modifications.

Accounting for Suspended Loads

Industrial facilities often require massive HVAC ducts, heavy cable trays, and fire sprinkler mains to be suspended from the roof structure. Unlike concrete, where anchors can sometimes be added post-construction, PEB rafters must be engineered from day one to carry these specific collateral point loads. At MAXXINFRA, we collaborate with MEP consultants during the 3D modeling phase to ensure the primary and secondary framing (purlins) are correctly sized for these suspended utilities.

Web Penetrations and Routing

Routing large ducts or pipes through deep steel beams can save valuable headroom. However, cutting holes in the web of a structural member alters its load-bearing capacity. If web penetrations are required, they must be identified during the detailing phase. Our engineering team calculates the required reinforcements (such as welded doubler plates or stiffeners) and these penetrations are precisely cut by CNC plasma machines in our factory, preserving the member's structural integrity.

Clash Detection via BIM

The most effective way to integrate MEP into steel is through Building Information Modeling (BIM). By importing the MEP consultant's 3D models into our Tekla structural model, we run automated clash detection. This identifies any intersection between steel bracing and HVAC ducts or piping before a single piece of steel is fabricated, eliminating site delays and rework.
