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.

Also included in a CD scope
Drawing index and sheet setup · Demolition and phasing plans · Specifications in CSI MasterFormat three-part sections, or as short-form notes on the drawings — whichever your office uses · 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.
Healthcare
Healthcare — the work most outsourcing firms won’t take
Healthcare is unforgiving and the review process is its own discipline. We take it because our founder spent seven years at IMEG Corp’s India office with roughly 95% of his work on healthcare, including HCAI and OSHPD projects, and every healthcare package gets senior review.
Mechanical
Pressure relationships, air changes and filtration to FGI Guidelines and ASHRAE 170 In California, to CMC Chapter 4, Table 4-A — which adopts ASHRAE 170 with state amendments Isolation and protective environment rooms, with pressure monitoring Operating room and procedure space ventilation
Electrical
Essential electrical systems to NFPA 99 and NEC Article 517 Type 1 systems — life safety, critical and equipment branches Generator and transfer switch arrangement Patient care space classification
Plumbing and medical gas
Medical gas and vacuum to NFPA 99 Zone valve boxes, area alarms and outlet counts by space type Source equipment sizing and manifold arrangement Sanitary, sterilizer and lab waste separation
Review and coordination
HCAI and OSHPD submittal documentation and back-check responses Seismic anchorage and bracing coordination, including preapproved details Infection control risk assessment coordination and phasing plans Above-ceiling coordination in tight interstitial space
We produce the documentation. Your PE remains engineer of record, files with HCAI or your AHJ, and handles anything requiring an Inspector of Record or a site presence. On existing-facility work we can sequence and detail a tie-in, but the field verification behind it comes from your team.
Energy compliance
Energy code compliance, in all fifty states
Most jurisdictions run IECC or ASHRAE 90.1, and we submit COMcheck on the prescriptive path or model the performance path. Where a state runs its own regime we work in that instead. The adopted edition and its local amendments are confirmed in the proposal before we start, and the completed forms are issued with the set for your seal.
Most states — IECC and ASHRAE 90.1
COMcheck on the prescriptive path, or the performance path via energy modeling. Envelope, mechanical and interior lighting compliance forms, prepared to the edition your jurisdiction has adopted.
Florida energy code in EnergyGauge
Title 24 Part 6 documentation. Certificates of compliance for mechanical, indoor lighting and envelope, prepared in EnergyPro on our own license.
States running their own regime
Florida Building Code Energy Conservation forms, prepared in EnergyGauge, Washington’s WSEC, New York’s stretch code, and the state amendments in place elsewhere. Tell us the jurisdiction and we confirm in writing what we can produce before you commit.
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.

Quoted per project
Sheet counts are typical for a full M+E+P construction document set and vary with system complexity. These are typical, not fixed. Every project and every office works differently, so lead with the date you need and we will tell you within four working hours whether we can hold it. Standard schedules assume complete architectural backgrounds at kickoff. Expedited work displaces other jobs, is priced accordingly, and depends on current capacity — ask rather than assume.
