MECHANICAL ENGINEERING
Mechanical Construction
Documents
Permit-ready mechanical drawing sets — schedules, details, and sheet production built to your firm’s standards,
tailored to what makes a mechanical set complete.
Our Founding and Mission
Introduction
The construction document phase is where every prior mechanical design decision — load calculations, equipment selection, ductwork routing, and hydronic layout — comes together into a coordinated, permit-ready drawing set. NexMEP Global LLC supports U.S. MEP consulting firms with mechanical construction document production, assembling sheets, schedules, and details from the design your engineering team has developed and approved through earlier phases.
Unlike the discipline-specific design work covered on our other mechanical service pages, this stage is about assembly, cross-checking, and finishing: taking approved duct routing, piping layout, load results, and equipment selections and turning them into a sheet set that reads clearly, submits cleanly, and stands up to a plan reviewer’s scrutiny.
DESIGN ACCURACY & COMPLIANCE
Why This Service Matters
Construction document production is detail-intensive work: schedules must match plans exactly, details must reflect the specific conditions of the project, and sheet sets must be internally consistent from cover sheet to the last detail. Inconsistencies at this stage generate plan review comments, contractor RFIs, and change orders during construction — and because mechanical sets typically involve more schedules and cross-references than most other disciplines, they are particularly vulnerable to this kind of error if not carefully checked.
Because this phase often falls at the busiest point in a project schedule, production support here has an outsized effect on keeping a project on track for permit submission, freeing your engineers to focus on final design review rather than sheet assembly and cross-checking.

Calculations
Software, Workflow & Coordination
Rigorous backup calculations formatted directly for permit submission and QA/QC documentation.
Software & Production Workflow
Construction documents are produced in Revit and AutoCAD MEP using your firm’s established templates and standards, with sheet production sequenced to match your project’s design development into a fully detailed, coordinated set. We track outstanding items, pending details, and schedules in a shared status log to ensure total visibility ahead of submission.
Revit & AutoCAD Coordination
Final coordination includes a comprehensive Navisworks clash detection pass across all disciplines, ensuring views reflect current model states. We verify that all sheet references, detail callouts, and keynotes resolve accurately without orphaned tags, while keeping fast-track and phased-issuance submissions completely consistent.
