MECHANICAL ENGINEERING
Hydronic Systems
Chilled water, hot water, and piping distribution layouts coordinated for accurate,
buildable hydronic systems.
Our Founding and Mission
Introduction
Hydronic systems introduce a distinct set of design and coordination challenges — pipe sizing, pump selection support, and layout routing that must account for building pressure zones and equipment room space. NexMEP Global LLC supports U.S. MEP consulting firms with hydronic system production, including chilled water and hot water piping layouts, pump and equipment room coordination, and distribution system documentation, all developed from your engineer’s system design and control narrative.
Hydronic piping layout often requires more iterative coordination than other mechanical systems because equipment rooms are typically the most space-constrained area of a building. Our team treats equipment room layout as a priority early-stage task rather than something deferred until later in design development.
DESIGN ACCURACY & COMPLIANCE
Why This Service Matters
Hydronic piping systems are typically installed in the same ceiling and shaft spaces as ductwork, electrical, and plumbing, making early and accurate coordination essential to avoiding conflicts. Pipe sizing errors or overlooked pressure drop across long distribution runs can affect system performance long after construction is complete, sometimes only becoming apparent once the building is occupied and the system is fully loaded.
Production support allows detailed piping layout and coordination work to proceed on schedule, giving your engineers a fully developed system to review rather than a preliminary layout requiring significant additional development, and reduces the risk that equipment room congestion is discovered only during construction, when changes are far more disruptive and costly.

Calculations
Software, Workflow & Coordination
Rigorous backup calculations formatted directly for permit submission and QA/QC documentation.
Software & Production Workflow
Hydronic piping is modeled in Revit MEP using your firm’s piping system families and sizing parameters, developed alongside ductwork and other trade routing. Equipment room layouts are modeled early and reviewed prior to distribution piping development to optimize space constraints and ensure system alignment.
Revit & AutoCAD Coordination
Piping routing undergoes routine Navisworks clash detection against structural framing, ductwork, electrical conduit, and plumbing. We check maintenance clearance for valves, strainers, and expansion joints while coordinating structural anchor and guide locations for long pipe runs.
