MEP and HVAC

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.

Steps on every project

Coordination

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,

one coordinated design

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.

Send your files

Architectural plans, equipment preferences, utility information and site address.

We confirm criteria

Code edition, design conditions, systems in scope and deliverables.

We calculate

Heating and cooling loads, electrical loads and plumbing fixture units are calculated.

We design and coordinate

Systems are drafted and equipment connections are assigned across the trades.

You receive the package

MEP drawings, schedules and calculations, with stamping requirements confirmed for your state and scope.

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.

Delivery formats

Drawing sets, calculation reports and any native files are agreed in your proposal.

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.

Which HVAC calculations do you provide?

Heating and cooling loads are calculated for the building and systems in scope. The calculation method and supporting reports are confirmed for your project.

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 provide PE-stamped MEP drawings?

Share your project city and state. Stamping availability, the responsible engineer and the disciplines covered are confirmed before the scope is agreed.
