Mechanical, electrical and
plumbing — schematic design
through record drawings.
Scoped by discipline and by design phase, so you can price us into your own proposal
without a call. Where we don’t cover something, we say so plainly.

All three disciplines engineered in-house by our own staff. Site visits and field verification stay with your firm — see below.
Scope detail
What's included, by discipline
Mechanical/HVAC
Block and room-by-room loads Equipment selection and schedules Duct layout, sizing, static pressure Hydronic piping layout and sizing Ventilation to ASHRAE 62.1 Details, sections, sequences of operation Demolition and phasing plans
Electrical
Load calcs to NEC Article 220 Service and feeder sizing, one-lines Panel schedules, connected and demand Voltage drop and short-circuit checks Lighting with photometrics to IES Egress, emergency, legally required standby Low-voltage, fire alarm device layouts
Plumbing
Fixture units and sizing per IPC / UPC Domestic water pressure and pump calcs Sanitary, vent and storm layouts Riser diagrams, fixture schedules Storm sizing to local rainfall intensity Natural gas load and sizing Water heater sizing, specialty piping
Also included in a CD scope
Drawing index and sheet setup · Demolition and phasing plans · Specifications [ in CSI MasterFormat three-part sections / as short-form notes on the drawings ] · Deferred submittal coordination · General notes, legends and abbreviation sheets
Specialist studies
Power systems studies — the electrical work most firms sub out
Modeled, run and reported by our own electrical engineers. If you already send this work outside your firm, you’re
only changing who does it.
Studies we produce
Short circuit and fault current analysis
Protective device coordination
Arc flash hazard analysis to IEEE 1584 and NFPA 70E, with equipment labels
Harmonic analysis to IEEE 519
Also available
Motor starting and voltage dip
Selective coordination for emergency and legally required systems
Grounding studies
Load flow and capacity checks
What we need from you
Field data collection and the utility fault current letter. Since we don't attend site, equipment nameplate data, conductor lengths and one-line verification come from your team. We build the model, run the study, and produce the report and labels for your review and seal. Study method and software are confirmed in the proposal; where you need native SKM output, we work on your seat with your written authorization.
Energy compliance
Energy code compliance, in any U.S. jurisdiction
We work to the code edition your AHJ has actually adopted, not a generic model code, and deliver the
completed forms with the set for your seal.
IECC and ASHRAE 90.1 states
COMcheck prescriptive path, or the performance path via energy modeling. Envelope, mechanical and interior lighting compliance forms, prepared to the adopted edition.
California — Title 24
Title 24 Part 6 documentation. Certificates of compliance for mechanical, indoor lighting and envelope, prepared in EnergyPro on our own license.
Florida
Florida Building Code Energy Conservation forms, prepared to the current edition and issued with the mechanical package.
Local amendments and stretch codes are confirmed at proposal stage. If your jurisdiction runs its own forms, tell us before you commit and we’ll confirm in writing whether we can produce them.
After issue
We don't disappear at CD
The weeks after a set is issued are when most firms need help and most outside teams have already moved on. We stay on the project.
Submittal review
Equipment submittals and shop drawings checked against the specified basis of design and the schedules. Marked up with exceptions noted, returned for your sign-off.
RFI responses
Drafted responses with the revised detail or sketch attached. Where an RFI turns on field conditions, you supply the observation and we draft from it.
Plan review comments
AHJ comments addressed, drawings revised, deferred submittals coordinated, and a response letter drafted for your review and signature.
Everything here is drafted for your review and issued under your seal. You remain the decision-maker on every response; we do the work behind it.
Fire protection, civil and structural — when you need it bundled
Fire protection
- Sprinkler and standpipe layouts
- Hydraulic calculations
- Fire pump sizing coordination
- Fire alarm device coordination
Civil
- Site utility routing
- Invert coordination
- Grading and drainage
- Storm water conveyance
Structural
- Framing coordination
- Penetrations and sleeves
- Equipment support coordination
- Roof curb and dunnage layouts
Delivered through a vetted extended team, contracted and managed by us as a single NexMEP scope with one point of contact and one invoice. MEP remains our in-house discipline.
What we don't do
- We do not seal or stamp drawings
- We do not serve as engineer of record
- We do not perform site visits or field verification
- We do not attend owner, AHJ or contractor meetings
- We do not hold or pursue your client relationship
- We do not submit to jurisdictions on your behalf
Every one of these stays with your firm, where the license and the liability already sit. If a scope needs
something on this list, tell us early and we’ll say plainly that it isn’t ours.

firm standardizes on, we work on your license with your written authorization. Still on an older release? Tell us the version and we’ll match it.

Ranges assume complete architectural backgrounds at kickoff and one round of review comments. Your actual schedule is fixed in the proposal.
Getting started
What we need from you to quote and start
For a lump-sum fee within 24 hours, the first three are enough. The rest we collect at kickoff.
To quote
- Architectural backgrounds at current issue
- Scope and phase you want covered
- Jurisdiction and target submission date
At kickoff
- Your title block, layer standards or Revit template
- Governing code edition and AHJ amendments
- Basis of design or design narrative, if one exists
- Ceiling heights and plenum constraints
- Owner or utility requirements
- Point of contact and review cadence
Send us a set of drawings.
You’ll have a lump-sum proposal within 24 hours. No call required first, and a
mutual NDA is available before you send anything.
