Multifamily Estimates Built Around Units, Floors, and Buildings

BidAccurate provides multifamily construction estimating services for apartment projects across the United States. We work from your architectural, structural, civil, and MEP drawings and specifications to produce quantity takeoffs and priced estimates for the full building or for the trades you bid.

Apartment projects repeat the same unit plans many times, mix construction types, and add amenities, parking, and site work on top. We organize each estimate by unit type, floor, and building, so your team can check the numbers, compare bids, and update the estimate when the unit mix or design changes.

  • Takeoffs by unit type, floor, and building
  • Podium and upper floors estimated separately
  • Rated wall and floor-ceiling assemblies
  • Unit and common-area MEP counts
  • Amenity, parking, and site cost centers
  • Excel reports with color-coded plan markups

What makes multifamily different

Multifamily Estimating Challenges and How We Handle Them

Apartment buildings look repetitive, but the cost risk is in the details: unit variations, construction types, rated assemblies, stacked systems, and the spaces outside the units.

  1. 01

    Repetitive unit types

    Apartment buildings repeat a small number of unit plans many times, with mirrored, corner, and accessible variations. A small error in one unit takeoff is multiplied across the whole building.

    How we handle it

    We take off each unit type once, check mirrored and accessible versions separately, and extend the quantities using unit counts confirmed against the unit matrix and floor plans.

  2. 02

    Podium and mixed construction types

    Many mid-rise projects combine wood or light-gauge framing above a concrete podium, often with structured parking. Each part has different materials, crews, and code requirements.

    How we handle it

    Quantities are split by construction type and level, so podium concrete, reinforcing, and post-tensioning stay separate from the framing, sheathing, and assemblies above.

  3. 03

    Fire and sound separation assemblies

    Unit demising walls, corridor walls, shafts, and floor-ceiling assemblies carry fire-resistance and acoustic requirements that add layers, materials, and labor.

    How we handle it

    We measure each wall and floor-ceiling type as drawn, using the assembly designations from the drawings, so rated and acoustic assemblies are priced as complete systems.

  4. 04

    Stacked MEP systems

    Plumbing risers, unit fixtures, HVAC equipment, meters, and panels repeat by unit and stack by floor, while common areas and the roof have their own systems.

    How we handle it

    Fixtures and devices are counted per unit type, while risers, mains, and equipment are measured by floor and system, so unit and common-area costs stay visible.

  5. 05

    Accessible unit requirements

    Covered multifamily buildings must meet federal Fair Housing Act accessibility requirements, and many projects specify ICC A117.1 Type A and Type B units with different layouts and fixtures.

    How we handle it

    Accessible units identified in the documents are taken off as their own unit types, so clearances, grab-bar backing, fixtures, and hardware are not averaged into standard units.

  6. 06

    Amenities, common areas, and site

    Lobbies, fitness rooms, clubhouses, pools, parking, and site work are one-off scopes that can be missed when the estimate focuses on the units.

    How we handle it

    We estimate amenity spaces, back-of-house areas, parking, and site work as separate cost centers, so they can be priced, compared, and reviewed on their own.

From feasibility to change orders

Estimating Support at Every Project Stage

Multifamily budgets change as the design develops, financing is arranged, and the project is bought out. We update the estimate at each stage, so you can see what changed and why.

  1. Stage 1 · Feasibility

    Conceptual budgets

    Early estimates based on the unit mix, building massing, and assumptions you approve, to help test a pro forma.

  2. Stage 2 · Design

    Design development updates

    Quantities updated as the drawings develop, with a list of what changed and the assumptions still open.

  3. Stage 3 · Bidding

    Bid-ready estimates

    Complete takeoffs and priced estimates from construction documents, organized by trade or bid package.

  4. Stage 4 · Value engineering

    Alternates and VE options

    Side-by-side pricing of alternate systems, materials, and finish levels shown or requested.

  5. Stage 5 · Construction

    Addenda and change orders

    Revised quantities for addenda, bulletins, and change orders so cost changes can be checked.

Developers and owners

Budgets at each design stage

Independent estimates to compare with the pro forma, contractor pricing, and design changes.

In-house estimators

Overflow estimating support

Extra capacity during busy bid periods, delivered in a format your team can review and reuse.

Turn Apartment Drawings into Clear, Comparable Numbers

Cost visibility by unit type

See the cost behind each unit plan, so changes to the unit mix can be priced quickly.

Separate common-area costs

Amenities, corridors, parking, and site work are shown on their own instead of spread across units.

Cleaner buyout packages

Trade breakdowns that match how multifamily work is bought, making bid comparisons easier.

Reviewable quantities

Excel reports and color-coded plan markups that show where every quantity came from.

Got Questions?
We've Got Answers.

What documents do you need for a multifamily construction estimate?
Send the current architectural, structural, civil, MEP, and landscape drawings with the unit plans, unit matrix, door and finish schedules, specifications, addenda, project location, and bid deadline. Tell us which trades or bid packages you need, whether you need quantities only or a priced estimate, and include any owner standards, alternates, or allowance lists.
How do you handle repetitive apartment unit types?
We take off each unit type separately, including mirrored and accessible variations, and confirm the unit count by type and floor against the unit matrix. We then extend the unit quantities and estimate corridors, stairs, amenity spaces, back-of-house areas, parking, and site work on their own, so a change to the unit mix can be traced through the estimate.
Can you estimate podium and mixed construction-type buildings?
Yes. When the documents show wood or light-gauge framing over a concrete podium, or a separate parking structure, we split the quantities by construction type and level. The podium concrete, reinforcing, and post-tensioning shown on the plans stay separate from the framing, sheathing, and rated assemblies above, which makes it easier to compare structural alternates and buy out each package.
Which trades can a multifamily estimate include?
We can cover sitework, concrete, rebar, structural steel, framing and lumber, roofing, exterior cladding, insulation, doors and windows, drywall and rated assemblies, millwork and cabinetry, flooring, painting, finishes, plumbing, HVAC, and electrical. You can request the full project or only the trades your company bids.
Can you provide an estimate at the conceptual or design development stage?
Yes. With early documents we measure what is drawn and clearly list the assumptions behind anything that is not, such as typical unit layouts, finish levels, or MEP systems. As the design develops, we update the estimate to the newer drawings and show what changed, so your budget can be compared with each design stage.
Do you work on affordable, senior, or prevailing wage housing projects?
Yes. When a project is publicly funded or subject to prevailing wage, we organize the estimate around the specified bid forms, schedule of values, and labor rates you provide or tell us to use. We do not determine wage classifications or compliance requirements; those come from the contract documents and the agency that funds the project.
How long does a multifamily estimate take?
Turnaround depends on the building size and number of buildings, unit-type count, construction type, how many trades are included, document completeness, the level of pricing detail, alternates, addenda, and current workload. We review the documents first and confirm a delivery date before work starts.
Can you stamp drawings for multifamily projects?
BidAccurate offers stamping services in all US states. Tell us the drawings, the jurisdiction, and the permit or submission requirements, and we will confirm the scope and timeline before work begins.
