MEP and HVAC engineering for buildings
Mechanical, electrical and plumbing designs with HVAC, prepared from your architectural plans. Each system is designed on its own, and every connection between trades is assigned before it reaches the field.

Equipment needs power, controls, drainage and supports from different trades
AM's MEP designs assign each connection, so nothing is left for another trade to assume.
A system design you have to piece together
What an uncoordinated set leaves open
? Who provides power and controls to this unit?
? Was the HVAC sized from a load calculation, or a rule of thumb?
? Does the duct route clear the structure?
? Is the electrical service sized for every new load?
? Where does the condensate drain go?
A design you can check
What AM Engineering delivers
✓ Heating and cooling loads calculated room by room
✓ Electrical load calculation and panel schedules
✓ Plumbing fixture units, pipe sizing and riser diagrams
✓ Equipment connections assigned to each trade
✓ Design criteria and code edition stated on the sheets
What we design →
Six MEP scopes, each designed to its own system
Mechanical, electrical and plumbing systems, coordinated where they meet.
HVAC
Heating and cooling load calculations, equipment selection, ductwork and ventilation design.
Mechanical piping
Hydronic, refrigerant and condensate piping with supports and connections.
Electrical power
Service and distribution sizing, panel schedules, load calculations and one-line diagrams.
Lighting and devices
Lighting layouts, controls, receptacles and device plans.
Plumbing
Domestic water, sanitary drainage, vents and fixture layouts with riser diagrams.
Controls and interfaces
Equipment connections, controls and supports assigned across the trades.
How it works →
From plans to a coordinated MEP design in five steps
Every MEP assignment follows the same review path, from one system to a full building.
1
Send your files
Architectural plans, equipment preferences, utility information and site address.
2
We confirm criteria
Code edition, design conditions, systems in scope and deliverables.
3
We calculate
Heating and cooling loads, electrical loads and plumbing fixture units are calculated.
4
We design and coordinate
Systems are drafted and equipment connections are assigned across the trades.
5
You receive the package
MEP drawings, schedules and calculations. [Confirm PE stamp]
Revisions and plan review
Reviewer comments are answered with revised sheets and a response letter that records what changed.
Accepted inputs
Architectural CAD or PDF plans, equipment cut sheets, utility letters and existing building drawings.
What you receive →
What every MEP package includes
Separate system drawings and a coordinated view of where the systems meet.
The MEP package
✓ Mechanical plans with equipment and duct layouts
✓ Electrical plans, panel schedules and one-line diagram
✓ Plumbing plans and riser diagrams
✓ Load calculations for HVAC, electrical and plumbing
✓ Equipment schedules with connection responsibilities
Systems kept separate
Each system has its own drawings, so a trade can review its scope on its own.
Connections assigned
Power, controls, drainage and supports are assigned to a trade for every unit.

Why AM Engineering →
Built so every connection has an owner
Seven habits that run through every MEP package.
Connections assigned
Power, controls, drainage and supports are assigned for every piece of equipment
Calculated, not guessed
HVAC, electrical and plumbing are sized from load calculations
Systems separate
Each trade's scope is drawn on its own, with a coordinated overview
Criteria on the sheets
Code edition and design conditions appear on the drawings
Clearances checked
Equipment, duct and pipe routes are checked against the structure and ceilings
Assumptions on record
Missing equipment or utility data is listed as a stated assumption
Plan review support
Reviewer comments are answered with revised sheets and a response letter
FAQ →
MEP and HVAC questions
Loads, equipment, codes and stamps.
Do you do Manual J and duct design? [To confirm]
Confirm which load calculation methods AM uses for residential and commercial HVAC.
Can you design for a tenant improvement?
Yes, from the existing building drawings or field information, with the new work shown separately.
Do you select the equipment?
Equipment is sized and scheduled from the loads. Final make and model can follow your preference.
Which code do you design to?
The mechanical, electrical and plumbing codes adopted by your jurisdiction. They are stated on the drawings.
Do you stamp MEP drawings? [To confirm]
Add the states where AM's engineers hold a PE license.
How long does an MEP design take? [To confirm]
Add typical turnaround for residential and commercial projects.
How is MEP design priced? [To confirm]
Add the pricing basis, for example per square foot or a fixed fee per project.
