Divisions 21–28 · Combined MEP
One MEP estimate covering fire protection through low-voltage, coordinated before bid day
When mechanical, electrical and plumbing are priced by three different estimators, the gaps show up where the trades meet: the sleeve nobody carried, the ceiling cavity that cannot hold both the duct main and the cable tray, the housekeeping pad left out of every scope. Our MEP estimators take off Divisions 21 through 28 together, run a routing check for clash allowances, build combined labor by floor and phase, and hand you a single bid summary that a general contractor can accept without a scope-gap meeting.

Overview
Why a combined MEP estimate is different from three trade estimates
A combined MEP estimate quantifies every system that moves water, air, power and data through the building as a single scope, organized by CSI division but reconciled across them. Fire sprinkler mains, domestic water, sanitary and storm risers, ductwork, hydronic piping, feeders, branch circuits, cable tray and fire alarm pathways are all taken off from the same calibrated set, floor by floor. Because one team measures all of it, the shared items that fall between trades are counted once and assigned deliberately: core drills and sleeves, housekeeping pads, roof curbs, equipment disconnects, control wiring, firestopping at rated penetrations and the seismic bracing that every system above the ceiling requires.
Coordination is priced, not assumed. We review the routing on the mechanical, plumbing and electrical sheets against the structural framing and ceiling heights, flag the corridors and mechanical rooms where duct mains, sprinkler branch lines, cable tray and sanitary slope compete for the same cavity, and carry a clash allowance in hours and material for rerouting. On BIM projects we read the federated model or clash report when one exists and convert the unresolved clashes into a measurable contingency rather than a round percentage. The same pass identifies owner-furnished equipment, phased shutdowns and after-hours tie-ins that affect every trade's labor.
Labor is built per division with the units each trade actually uses, then rolled up by floor and construction phase so the general contractor sees crew loading across all of MEP at once: underground, overhead rough-in, equipment setting, trim and startup. Material is priced the week the estimate is built, with copper, steel pipe, sheet metal and switchgear tracked as commodity lines you can refresh before award. The deliverable is one workbook with a tab per division, a shared-scope tab, a coordination tab and a bid summary that totals to a single number, plus marked-up plans with every system in its own color on the same sheet.

A second estimator audits quantities and pricing, documents assumptions and exclusions, and delivers your Excel workbook, PDF summary and marked-up plans.
Why LEEDS
Why contractors switch to LEEDS
An estimating desk that behaves like an extension of your team, not a software subscription.
- One estimating team measures all seven divisions from the same calibrated set, so shared items are counted exactly once.
- Clash allowances are quantified in hours and material from a routing review or BIM clash report, never a flat percentage.
- Core drills, sleeves, housekeeping pads, roof curbs and firestopping are assigned to a named trade in a dedicated shared-scope tab.
- Labor is rolled up by floor and phase across MEP so general contractors can see crew stacking before it becomes a schedule problem.
- Commodity lines for copper, steel pipe, sheet metal and switchgear are isolated so the bid can be refreshed if award slips.
- Controls, fire alarm and low-voltage are priced as part of the package or split out to match how you plan to subcontract.

FAQ
MEP Estimating FAQs
Straight answers on scope, turnaround, pricing and deliverables.
Why bid MEP as one package instead of three separate trade estimates?
Separate estimates each stop at the edge of their own division, which is exactly where sleeves, pads, disconnects, control wiring and firestopping get dropped. A combined estimate measures all seven divisions from one set, assigns every shared item to a named trade, and totals to a single number. General contractors spend less time leveling, and MEP primes avoid the margin erosion that comes from absorbing unassigned scope after award.
How do you quantify a BIM clash allowance?
When a federated model or clash report is available we count unresolved hard clashes by system pair and location, then assign rerouting hours and material to each. Without a model we run a routing review of duct mains, sprinkler branches, cable tray and sloped sanitary against structure and ceiling heights, and carry an allowance for the congested zones we identify. Either way the allowance is itemized, not a percentage.
Can you deliver the MEP estimate split by division for subcontracting?
Yes. The workbook already carries a tab per division with its own labor, material and markup, plus a shared-scope tab listing who owns each interface item. If you plan to self-perform mechanical and subcontract electrical, we move the shared items to match, so each trade's number is complete on its own and the sum still equals the combined bid.
Which labor units do you use across the different MEP trades?
Each division is priced with the units its own contractors recognize: NECA units for electrical and low-voltage, MCAA-style units for piping and sheet metal, and productivity rates by fixture and system for plumbing and fire protection. All of them are adjusted for ceiling height, occupied conditions and phasing, then rolled up by floor so the combined crew loading is visible.
What documents do you need for a full MEP package?
Fire protection, plumbing, mechanical and electrical plans with their schedules, risers and one-lines, the Division 21 through 28 specifications, and the structural and reflected ceiling sheets we use for the routing review. A BIM model or clash report is helpful but not required. For design-development sets we price at the system level and document every assumption.
How long does a combined MEP estimate take?
A complete package across all seven divisions for a mid-size commercial building typically takes three to five business days, because the coordination pass runs after the individual division takeoffs are finished. Scope-gap reviews of existing sub quotes return in 24 to 48 hours. Large hospitals and data centers are scheduled individually and we confirm the date before starting.
