FIRE PROTECTION ENGINEERING
Standpipe Systems
Vertical standpipe riser and hose connection production support coordinated with your engineer’s fire department access design.
Our Founding and Mission
Introduction
NexMEP Global LLC supports U.S. MEP consulting firms with standpipe system production, developing vertical riser layouts, hose connection locations, and system class documentation from your engineer’s design basis and the fire department access strategy established for the project. Our team carries standpipe layout through each design phase while your licensed fire protection engineers retain full authority over system class selection, pressure requirements, and code compliance approach.
We work from the standpipe class, hose connection locations, and pressure design basis your engineer provides, producing coordinated documentation that reflects that design intent accurately, consistent with the coordination this vertically distributed system requires across every floor of a building. Because standpipes exist specifically to support fire department hose operations, our documentation is built with the level of clarity a responding fire department, as well as the plan reviewer, needs to rely on it.
DESIGN ACCURACY & COMPLIANCE
Why This Service Matters
Standpipe systems exist to support fire department operations during an emergency, which means hose connection locations, pressure availability, and system class must be documented with precision the fire marshal will verify closely during plan review. Because standpipes run the full height of a building and typically share riser shafts with sprinkler piping, domestic water piping, and other vertical systems, coordinating standpipe routing without conflicts requires attention from the earliest design phase.
Production support allows this vertically repetitive but detail-sensitive documentation to be developed consistently floor to floor, reducing the risk that a coordination conflict on one level goes unnoticed because it was resolved differently on a similar level elsewhere in the building. A standpipe system that is inconsistent from floor to floor also complicates fire department familiarity with the building during an actual emergency response, which is a real-world consequence beyond the plan review process itself.
Our Capabilities

Calculations
Software, Workflow & Coordination
Rigorous backup calculations formatted directly for permit submission and QA/QC documentation.
Software & Production Workflow
Modeled in Revit MEP and AutoCAD using your firm’s standards. Shaft routing is synchronized with architectural stair cores early in design, supported by a floor-by-floor consistency check to lock down typical layouts.
Revit & AutoCAD Coordination
Shaft distribution is coordinated against structural framing and MEP utilities using Navisworks. We verify hose valve accessibility, door clearances, and visibility at every stair landing to avoid unexpected site conditions.
