Mechanical Drawings That Fit the Building Design

FirstPass prepares mechanical and HVAC drawings for permit, coordination and construction-documentation purposes.

Duct layouts, equipment and ventilation information are documented so the mechanical scope can be reviewed alongside the rest of the drawing set.

Quick Answer · M-100.QA

Mechanical and HVAC plans document duct layouts, diffusers, exhaust systems, ventilation and equipment so the mechanical scope can be reviewed alongside the rest of the drawing set. FirstPass prepares these sheets for permit, coordination and construction-documentation purposes, on residential projects such as additions and ADUs and on commercial work such as restaurants and tenant improvements. Equipment schedules, rooftop coordination and connections to electrical and plumbing can be included when the project calls for them.

For

Additions, new homes and commercial tenant improvements

You receive

Permit-ready mechanical and HVAC sheets (M-series)

Depending on scope, plans may include:

  • HVAC equipment locations
  • Supply and return layouts
  • Ductwork
  • Diffusers and grilles
  • Exhaust systems
  • Ventilation information
  • Equipment schedules
  • Mechanical notes
  • Equipment connections
  • Roof-mounted equipment coordination
  • Existing and proposed mechanical conditions

NoteSheet content follows the actual scope. Not every project needs every item.

M-101Coordination

Mechanical Plans Need Architectural Context

Mechanical design affects ceilings, walls, roof conditions, equipment spaces and other disciplines.

Mechanical scope rarely stands alone. Related drawings can be prepared through Architectural Drafting, Electrical Plans and Plumbing Plans, combined as MEP Drafting or included in a complete Permit Plan Set.

A coordinated set considers:

  • Ceiling heights
  • Equipment locations
  • Duct routing
  • Exhaust termination
  • Electrical requirements
  • Plumbing connections
  • Structural openings or supports
  • Access and service clearances

R-Series

Residential Mechanical Plans

Mechanical documentation can support additions, ADUs, major remodels and new construction.

Commercial Mechanical Plans

Restaurants, medical spaces, salons, gyms, offices, commercial kitchens and other tenant improvements may have ventilation, exhaust or occupancy-specific mechanical requirements that go beyond a simple equipment layout.

Mechanical Plan FAQs

Response

HVAC is a major part of mechanical documentation, but mechanical scope can also include ventilation, exhaust and other systems depending on the project.

Response

Where applicable information is provided, equipment locations can be coordinated with architectural, electrical and relevant structural documentation.

Response

They often involve additional exhaust, ventilation or equipment considerations, but actual requirements depend on the project and jurisdiction.

Response

Drafting and engineering are distinct services. Where engineering design, calculations or professional sealing are required, the project must involve the appropriate qualified professional.
