Commercial Estimating Services
Division-structured cost estimating for commercial buildings, core and shell projects, tenant improvements and development work — measured from your documents, organized for your bid, and ready for the scrutiny of owners, lenders and subs.
Commercial Estimating, Done the Way Bids Are Won
Commercial construction is priced differently from residential work, and the difference matters well before the number is written. Commercial projects are organized by CSI divisions, priced in phases that a bank and an owner can follow, and measured against documents that are rarely complete at the moment someone needs a cost. A commercial estimate that ignores that reality produces a number nobody on the project team can defend. One that respects it turns drawings, specifications and RFQ scopes into a cost model the whole team can interrogate.
The estimators at CEDS prepare commercial estimates the way the work is actually bought: core and shell as a building system, tenant improvements as construction inside somebody else's walls, and sitework as the long pole that decides the schedule. Every division — concrete, metals, wood and plastics, thermal and moisture protection, openings, finishes, mechanical, electrical — is measured from the documents, priced against current market data, and delivered as a standable line item. When a subcontractor's quote does not match the estimate line, you can see exactly which quantity or rate moved, because nothing lives in the estimate as a blanket number.
This is also why commercial estimates from CEDS carry a written assumption log as part of the deliverable, not as an afterthought. Commercial documents are notorious for gaps: a mechanical schedule marked "per engineer," an interior elevation missing a finish callout, a site plan with no utility depths. Every one of those gaps becomes a named assumption in the log — priced as a stated value, not as a surprise buried in the summary. That discipline is what keeps a commercial estimate alive through bid day, through award and through the first change order.
What's Covered in a Commercial Estimate
A commercial estimate is not one estimate; it is a portfolio of division-level estimates that share the same assumptions and the same document set. Whether you are bidding a new building, pricing a build-out or rolling a development pro forma, the same structured coverage applies. Below are the six areas that appear in essentially every full commercial estimate we produce.
Core & Shell
Structure, foundations, envelope, roofing and vertical circulation priced as the permanent building investment — the parts of the project that outlast any single tenant.
Tenant Improvements
Build-outs and TIs priced against lease plans, finish schedules and landlord work letters, so fit-out scope is measured as its own division and budget track.
MEP & Trades
Mechanical, plumbing, electrical and fire protection measured per trade with fixtures, equipment and devices itemized separately from rough-in labor.
Finishes
Drywall, ceilings, flooring, millwork, paint and specialty finishes measured by area and by room, tied to the finish schedule and interior elevations.
Site / Development
Sitework, utilities, paving, landscaping and hardscaping carried as their own division, including the long-lead infrastructure that controls the schedule.
Renovation
Reused structures where demolition, selective removal, protection and coordination with live occupancy are real scope — priced as written assumptions, never as hopes.
The coverage is always confirmed against the project type before measurement starts. A cold shell build-out does not need the same sitework depth as a ground-up building; a full renovation needs more demolition detail than a new build. Confirming the coverage up front keeps the estimate the right depth for the decision — never padded with divisions the project does not have, and never missing the ones it does.
Tenant Improvements & the Work Letter Problem
Tenant improvement estimating is where commercial cost estimating earns its reputation, because a TI is priced two ways at once: against the construction documents and against the landlord's work letter. The allowance in the lease, the landlord contribution, the tenant premium and the base building conditions all move the same square footage in different budgets. A TI estimate that ignores the work letter will miss who pays for what by thousands of dollars per suite.
CEDS treats TI work as its own estimating discipline. We separate the parts of the budget a landlord builds (base building work, shell conditioning, vertical penetrations) from the parts a tenant builds (demised-area improvements, finishes, furniture casework, specialty systems). The estimate is structured so the allowance can be checked line by line against the letter — which means the answer to "where did the allowance go?" is a set of measured lines, not a shrug and a re-budget.
The same discipline covers the common commercial truth that the first set of TI documents is almost never the last. Plans come in at SD level, prices are needed for lease negotiations, and the design iterates through DD to CD while the broker watches the calendar. Our TI estimates are structured to be refined rather than redone: the measurement baseline stays fixed, the finish schedule updates, and the delta between allowance and actual stays visible in every revision.
- Base building work separated from demised-area improvements line by line
- Allowances checked against the landlord work letter before a number is issued
- Core and shell scope identified separately from tenant finish scope
- Furniture, fixtures and equipment kept out of the construction estimate
- Finishes measured from the actual finish schedule and interior elevations
- Revisions tracked against the original baseline so cost creep stays visible
- Building code and fire rating assumptions stated per occupancy type
For brokers, developers and landlords, the same structured TI estimate feeds the other documents a deal needs: the tenant allowance reconciliation, the landlord contribution summary and the lender condition attached to the lease file. That is the quiet value of estimating a TI properly — the number survives being read by people who were not in the room when it was built.
How a Commercial Estimate Is Built
Every commercial estimate follows the same five-step sequence, and it is the same sequence whether the project is a 5,000 square foot dental office build-out or a 90,000 square foot multi-tenant retail building. The difference is depth, not process. Contractors who have watched us work on one commercial job know exactly what the next one will look like when it arrives.
Document Review — Including Specs
The full drawing set and the specification booklet are read together, not separately. Specifications carry load ratings, finish classes, equipment schedules and testing requirements that drawings alone cannot show — a commercial estimate that ignores specs is pricing a different building than the one designed.
Scope Confirmation
Inclusions, exclusions, format, division structure and turnaround are confirmed in writing before measurement starts. Anything unmeasurable, unknown or ambiguous is listed as an assumption so the estimate is a documented position, not a silent bet.
Measurement
Quantities are measured from the documents by division and assembly — concrete volumes, steel tonnage, wall and ceiling areas, equipment counts, linear feet of systems. Commercial measurement is organized so a division can be handed to a trade without re-measuring the project.
Pricing
Labor, material and equipment rates are applied to the measured quantities, organized by trade and refinement level. Subcontractor scopes are packaged for comparison, and pricing is dated so the validity window of the estimate is explicit.
Review & Delivery
The estimate is checked against the documents, structured for your bid form or budget format, and delivered with the assumption log, division breakdown and summary — ready for you to present, compare or price further with your own crews and suppliers.
Sample Commercial Estimate — By Division
Below is how a commercial estimate reads when it arrives: division by division, with the scope of each division stated so the cost can be interrogated. The example reflects a hypothetical 24,000 square foot single-story medical office shell with a complete TI package, and is shown only to demonstrate the structure your own estimate will follow.
| Division | Scope | Est. Cost |
|---|---|---|
| 02–03 — Site & Concrete | Excavation, foundations, slab on grade, walkways | $212,400 |
| 04–05 — Masonry & Metals | Structural steel, joists, misc. metals, masonry veneer | $248,700 |
| 06–07 — Wood, Thermal & Moisture | Framing, sheathing, roofing assembly, insulation, sealants | $168,300 |
| 08 — Openings | Doors, hardware, glazing, storefront, frames | $121,900 |
| 09 — Finishes | Drywall, ceilings, flooring, paint, wall protection | $233,600 |
| 21–23 — Mechanical | Plumbing, HVAC, ductwork, fire protection, specialty piping | $401,800 |
| 26 — Electrical | Power, lighting, fire alarm, low voltage, special systems | $287,400 |
| 31–33 — Earthwork & Utilities | Site grading, storm, sanitary, water, paving | $136,200 |
| Indicative Direct Construction Cost | $1,810,300 | |
Sample figures are illustrative only and are shown to demonstrate how a structured commercial estimate reads. Your estimate is prepared from your project's own documents, quantities and market pricing.
What You Receive
The commercial deliverable is built for the way a commercial project is managed: multiple people, multiple trades and multiple conversations about the same number.

- Assumption Log
- Every gap, spec note and unmeasured item documented — scope defense that survives bid day and award.
- Trade Packages
- Division-scoped packages sized for subcontractor solicitation, so vendor quotes compare cleanly.
- Alternate Summary
- Alternates and allowance options itemized separately from the base estimate, priced and ready to add or delete.
- Review Call
- Time to interrogate the number, ask questions and refine scope before the estimate is committed to a bid.
Alternates, Allowances & The SD/DD Set
- Alternates and deducts itemized with the base estimate, never merged into it
- Allowances for fixtures, finishes and equipment stated with their values
- SD/DD/CB status of the documents recorded in the estimate header
- Escalation and validity window stated so the number is dated, not dated silently

- Revisions tracked against the original baseline through the design cycle
Scoped, Priced and Ready for Bid Day
"We handed CEDS a 90-page TI set for a 22,000 SF office fit-out, eleven days before bid. The estimate came back organized by division with the alternates laid out one by one. Our mechanical and electrical subs priced it without a single re-question, and the allowance reconciliation with the landlord letter went through on the first pass. That estimate is now our house format for every build-out."

Commercial Estimating Questions
A budget quote is a single number built from square footage and unit rates, useful at the feasibility stage but not engineered for bidding. A commercial cost estimate is measured from the documents, priced by division and backed by an assumption log — built to be interrogated, compared against subcontractor quotes and defended after award. We provide both, and we are explicit about which level of detail a decision needs before we start.
Yes, and we consider it essential. Base building work, landlord allowances and tenant premium scope live in different budgets and are paid for by different people. We keep the two tracks separate in the estimate and reconcile the tenant allowance against the landlord work letter line by line, so the answer to where the allowance went is a set of measured lines rather than a lump-sum surprise.
We estimate from SD, DD and CD sets alike, with each level clearly treated for what it is. SD estimates use unit rates and labeled square-foot assemblies and are called feasibility numbers. DD estimates carry more measured items and defined allowances. CD estimates measure the building in full detail. The document level is stamped on the summary so the estimate is always used at the correct weight, and revisions are tracked against the original baseline rather than recreated.
They are treated deliberately: alternates and deducts are priced as their own line items and never merged into the base scope, and allowances for fixtures, finishes and equipment are itemized with their values and validity windows. That way an owner can add or delete an alternate without re-pricing the building, and the reconciliation between the estimate and the actual buyout is straightforward.
A full commercial estimate is typically delivered in seven to ten working days depending on the building size and the state of the documents. Smaller tenant improvements with a complete TI set can move faster, and large development estimates spanning multiple buildings are scheduled around your milestones. We lock the delivery date before starting and scope the work to land ahead of the bid deadline.
