Commercial MEP Estimating Services
From multi-story Class A office developments and urban hotels to retail shell buildings and tenant improvements, we deliver accurate, code-compliant mechanical, electrical, and plumbing estimates tailored to the commercial construction sector.
Commercial Property Types We Estimate
Each commercial facility requires distinct system sizing assumptions, occupancy diversity factors, and code compliance workflows.
Office Buildings & High-Rises
Core-and-shell distribution, central VAV rooftop systems, chilled water risers, high-density electrical busways, networked lighting controls (Lutron/nLight), and tenant metering.
Hotels & Hospitality
Individual guestroom VTAC/PTAC and 4-pipe fan coil systems, commercial kitchen grease waste systems, central domestic water heating with return loops, and life-safety backup power.
Retail Centers & Malls
Packaged rooftop unit (RTU) schedules, tenant electrical sub-metering, gas branch lines for restaurants, parking lot lighting photometric takeoffs, and wet pipe sprinkler grids.
Multifamily & Mixed-Use
High-efficiency heat pump split systems, domestic water PEX riser manifolds, unit load calculations per NEC 220, centralized corridor ventilation, and sound-attenuated drainage piping.
Tenant Improvements (TI)
Fast-turnaround demolition and retrofit takeoffs: duct relocation, diffuser drops, branch circuit re-wiring, lighting swap to LED, and restroom fixture tie-ins to existing stacks.
Educational & Institutional
Classroom DOAS ventilation with energy recovery (ERV), science lab plumbing and acid-waste neutralization, mass notification fire alarm, and robust public restroom fixture banks.
Critical Commercial MEP Factors We Account For
In commercial estimating, missing code-mandated line items can eliminate a contractor's profit margin on bid day. Here is how we safeguard your estimates:
ASHRAE 90.1 & State Energy Code Compliance
We track requirements for economizers, automatic daylight harvesting, automatic receptacle shut-off, and minimum motor efficiency ratings across California Title 24, NYC LL97, and IECC jurisdictions.
Ceiling Plenum Congestion & Clash Risk
When architectural ceiling heights leave only 24 to 36 inches of plenum space, standard routing fails. We identify shaft congestion and coordination pinch-points between HVAC supply duct, fire sprinkler mains, and electrical cable trays before bid submission.
Long-Lead Equipment & Procurement Tracking
Commercial switchgear (40–60 weeks) and central chillers (26–42 weeks) carry massive schedule risk. Across our commercial electrical estimating and commercial HVAC takeoff workflows, we clearly timestamp equipment lead times and flag early procurement requirements in our estimate summaries.
Frequently Asked Questions
What commercial building sectors do you estimate?
We provide MEP estimating across all major commercial categories: Class A office buildings, retail malls, multifamily apartments, hospitality hotels and resorts, mixed-use towers, educational facilities, and commercial tenant improvement (TI) fit-outs.
How do you estimate HVAC systems in commercial high-rise buildings?
High-rise commercial HVAC requires careful accounting of riser static pressure drops, thermal expansion loops, vertical shaft fire/smoke damper ratings, floor-by-floor VAV terminal unit zoning, and central chilled water vs. condenser water loop distribution.
How are energy codes like ASHRAE 90.1, Title 24, and NYC LL97 accounted for in commercial estimates?
Commercial energy codes dictate specific mechanical and electrical components: daylight-responsive lighting controls, economizer enthalpy controls, high-efficiency heat recovery ventilators, and low-GWP refrigerants (R-454B/R-32). We incorporate jurisdiction-specific code allowances for every project.
