Mechanical Shop Drawings

Mechanical shop drawings are detailed, fabrication‑ready drawings that show exactly how HVAC and mechanical systems will be installed in the field. They include ductwork layouts, mechanical piping, equipment connections, hanger locations, elevations, sections, and all dimensions required for accurate installation.

Mechanical shop drawings are commonly required by:

• Mechanical contractors
• HVAC contractors
• Plumbing contractors (for combined MEP packages)
• General contractors
• BIM managers
• Owners and facility managers

They are often a contractual requirement before fabrication or installation can begin.

Accurate shop drawings:

• Reduce field rework
• Prevent clashes with other trades
• Improve installation accuracy
• Support fabrication and prefabrication
• Speed up project schedules
• Ensure compliance with approved submittals and specifications

They are essential for delivering a coordinated, buildable mechanical system.

We typically require:

• Contract-conformed design drawings
• Architectural and structural backgrounds
• Project & mechanical specifications
• Approved mechanical submittals
• Equipment schedules and cut sheets
• BIM execution plan (if applicable)
• Any GC/owner standards or templates

If anything is missing, we’ll let you know immediately.

Yes. All equipment, fittings, valves, and system components are modeled using manufacturer‑accurate dimensions to ensure proper fit, alignment, and installation in the field.

Yes. We provide hanger locations, rod sizes, spacing, elevations, and support details based on project requirements and industry standards.

Absolutely. We provide full 3D coordination using BIM tools such as Revit and Navisworks.
This includes:

• Clash detection
• Mechanical room coordination
• Overhead coordination with plumbing, electrical, and fire protection
• Routing adjustments to achieve a fully coordinated model

Yes. All mechanical shop drawing packages include:

• Plan views
• Elevations
• Detailed sections
• Enlarged views for congested areas
• Mechanical room detailing

These help installers understand exactly how systems should be built.

Yes. We provide detailed piping spool drawings with:

• Spool maps
• Weld locations
• Cut lengths
• Bill of materials
• Tagging and numbering
• Isometric views

These are ready for fabrication shops.

Yes. All shop drawings are developed using:

• Approved submittals
• Project specifications
• Manufacturer data
• Contract documents

This ensures full compliance with project requirements.

Yes. When required, we incorporate field‑verified dimensions to ensure accurate alignment with existing conditions.

We primarily use:

• Autodesk Revit
• Autodesk Navisworks
• AutoCAD (when required)

This ensures compatibility with GC and BIM manager workflows.

Timelines vary based on project size, but most packages are completed within:

• 1–2 weeks for small projects
• 3–6 weeks for medium projects
• 6+ weeks for large commercial or industrial facilities

We always provide a clear schedule before starting.

Yes. As a licensed Professional Engineer (PE), we can stamp drawings when required for permitting or owner approval.

Typical deliverables include:

• Coordinated 3D model
• Plan views
• Sections and elevations
• Hanger and support drawings
• Equipment connection details
• Sleeve and penetration drawings
• Spool drawings (if requested)
• PDF and DWG/Revit files

Yes. Revisions are included as part of our coordination and shop drawing process.
We maintain strict version control so all trades work from the latest documents.

Simply contact us with your project documents, and we’ll provide:

• A clear scope
• A fixed price
• A schedule
• A list of required information

Once approved, we begin modeling immediately.
