Mechanical
- Cooling and heating loads by area
- Equipment selections and locations
- Duct routing and ceiling space
- Ventilation and outdoor air for the space
Mechanical, electrical, and plumbing plans show how the building systems will serve your space. We prepare equipment layouts, loads, circuits, and piping details, then coordinate them with the architectural and structural drawings.
Electrical
- Service and panel sizing
- Load calculations
- Circuits, devices, and fixture layouts
- Disconnects and equipment connections
Plumbing
- Fixture layouts and counts
- Water and drain routing
- Water heater and equipment specifications
- Wet wall coordination with the framing
Schedules and notes
- Equipment schedules with model information
- Fixture and device schedules
- Notes the plan reviewer expects to read
- Code references where they help the review
Coordination
- Ceiling heights checked against ductwork
- Structural members worked around
- Equipment access and service clearances
- Reflected ceiling plans when the project needs them
Small commercial MEP
- Tenant improvements and build-outs
- Change-of-use projects
- Restaurants, salons, offices, and shops
- Multi-discipline sets with one point of contact
Review comments
Common MEP review comments.
Our MEP review responses address mechanical, electrical, and plumbing coordination. Common issues include missing equipment information, ventilation details, and circuit labels.
Missing equipment information
We need equipment model numbers and ratings to check the loads; a note saying equipment is to be determined leaves that information missing.
Ventilation that was not addressed
We check the ventilation requirements for bathrooms, kitchens, and commercial spaces, including on small projects.
A circuit that is not labeled
Panel sizing needs circuit labels and demand information so the reviewer can check what the panel serves.
Equipment that changed after submittal
A swapped unit or a different water heater means the drawings no longer match what is being installed.
Common questions
Before you send the set.
Do I need to pick the equipment first?
Equipment selections help us confirm the loads. If you have not selected equipment yet, we can use expected loads, note the basis of design, and update the schedule once you make the selections.
Can you work with equipment that is already installed?
Yes. Photos of equipment data plates help us identify what is installed. We review that information with the existing layout and permit requirements, which is common on after-the-fact projects.
Do you handle the calculations?
Yes. Load calculations, service sizing, and the supporting documentation are prepared as part of the MEP scope when the project needs them.
Who do I coordinate with on site?
We coordinate with the mechanical, electrical, and plumbing contractors on equipment selections, routing, and installation questions related to our drawings.

Start a project
Send the plans and how the space is used.
If you have chosen the equipment, send the manufacturer's specifications. Otherwise, describe how the space will be used and we will outline the information needed to start.
