Multifamily takeoffs
Unit-type matrices, repeated floor plates and finish schedules for Somerville's 86-unit multifamily pipeline, priced by building rather than by unit.
EA · SF · CYSomerville permits run almost entirely to multifamily, and Middlesex County infill sites punish loose quantities. We produce division-organized takeoffs from your plan set in 24–48 hours.
Somerville pricing is driven by dense infill logistics and tight staging, Middlesex County union labor rates, Boston-area life-sciences and lab fit-out demand, older housing stock with unknown subgrade conditions, and cold-weather concrete and envelope sequencing that compresses the construction calendar.
Somerville sits inside the tightest construction market in Massachusetts. The city issued permits for 90 new privately-owned residential units in 2025, and 86 of them — 96 percent — were multifamily. Only 4 were single-family. That mix tells you what your takeoff has to survive: mid-rise wood and concrete frames, podium and garage scopes, and unit-count-driven finish schedules rather than one-off custom details. Our Massachusetts construction estimating work is built around that reality.
Middlesex County sites bring their own estimating problems. Narrow lots near Union Square and Davis Square leave no room for material stockpiles, so handling and hoisting costs land in your general conditions instead of your trade packages. Older parcels often carry unrecorded fill, which pushes foundation quantities toward over-excavation and backfill allowances you cannot see on the drawings. We price from your plan set with ZIP-code-adjusted material and labor rates, deliver Excel and PDF takeoffs organized by CSI MasterFormat division with marked-up plan sets, and turn most projects in 24–48 hours.
For bidders. You need quantities you can defend in a bid review. We return division-sorted takeoffs with marked-up plans so every line traces back to a sheet, letting you adjust waste factors and labor crews before the bid date.
For builders. You are buying out trades on a live schedule. We break scopes by division and unit type so you can compare subcontractor quotes line by line and catch omissions before contracts are signed.
For owners. You want a budget before design is finished. We estimate from schematic sets, flag scope gaps and give you a cost basis you can track as drawings develop toward permit.

90 new housing units in 2025 (+8.4% vs 2024).
4 single-family · 86 multifamily (96%).
Somerville's 2025 residential permits totaled 90 units against 83 in 2024, an 8 percent increase. The headline number looks modest, but 86 multifamily units against 4 single-family units means nearly every project is a multi-unit building. Permitted value reached $12M, averaging $136,400 per unit — a figure that reflects unit count rather than the full construction cost of dense urban buildings, since it covers new privately-owned residential units only. For bidders, the practical read is that your estimating effort belongs in unit-type repetition: typical floor plates, repeated kitchen and bath stacks, and a framing takeoff that scales by floor rather than by building. Our multi-family estimating services are organized that way.
Somerville ranked 11th of 25 covered state cities by residential units permitted, with about 2 percent of the 4,601 units permitted across those cities. That places it in the middle of a market dominated by Boston's life-sciences and infill construction, which keeps subcontractor pricing and labor availability tight across Middlesex County. Nearby Newton and Waltham compete for the same crews and suppliers, so bid pricing moves together. If you are bidding work in Lawrence or Framingham at the same time, expect different productivity assumptions for travel, staging and inspection scheduling even where material pricing is similar.

The city's 2025 permit data shows 96 percent of new residential units were multifamily. That shapes the property types we price most often here.
Wood-framed over podium or concrete garage, typically 4 to 6 stories with unit-count-driven finishes. We take off by floor and unit type so quantities track the schedule.
Watch for: Unit mix repetition, balcony and corridor counts, fire-rated assemblies.
Older three-story wood buildings with porches and uninsulated walls. We separate demolition, structural repair, and new MEP from the new-work scope.
Watch for: Existing framing condition, lead and asbestos allowances, egress stairs.
Concrete podium decks over parking with waterproofing and fire separation. We quantify slab thickness, post-tensioning, and garage ventilation separately.
Watch for: Slab openings, waterproofing transitions, garage exhaust and detection.
Narrow-lot houses on tight parcels where staging is limited. We price handling and hoisting in general conditions rather than burying it in trade packages.
Watch for: Limited laydown area, crane or pump access, foundation over-excavation.
Tenant improvements in existing shells with high MEP density. We break process piping, exhaust, and controls from base-building work so you can compare scopes.
Watch for: Fume hood counts, dedicated exhaust, vibration criteria, clean utilities.
Ground-floor commercial under residential floors, common near Assembly Row and Union Square. We separate storefront, residential, and shared back-of-house scopes.
Watch for: Storefront glazing, separate utility metering, sound transmission between uses.
Somerville sits in one of the highest-cost construction markets in the country. These are the local conditions that move your numbers.
Somerville enforces the Massachusetts State Building Code, which adopts the IBC with state amendments, plus the stretch energy code for many projects. Plan review can require multiple submissions for egress, fire separation, and energy compliance. Confirm the adopted code edition and any local amendments with the Somerville building department before you lock your permit timeline and inspection costs.
Massachusetts State Building Code · IBC · IECC stretch code · Somerville building departmentMuch of Somerville is underlain by glacial till, urban fill, and former tidal marsh near the Mystic River and Alewife Brook. Unrecorded fill and high groundwater push foundation costs toward over-excavation, dewatering, and deeper piles. We carry allowances for unsuitable soil and backfill, and we price foundation scopes separately so you can see the risk before you bid.
Glacial till · urban fill · Mystic River · Alewife BrookSomerville gets cold winters with freeze-thaw cycles, snow, and nor'easters. That drives frost-depth footings, insulated slabs, freeze protection for concrete, and temporary heat in winter. Coastal storm exposure adds wind uplift and water-management details. We include seasonal protection and snow removal in general conditions so your winter schedule does not surprise you.
Freeze-thaw · frost depth · nor'easters · wind upliftBoston-area labor rates are among the highest in the nation, and Somerville's dense infill work competes for the same crews as Cambridge and Boston. Prevailing wage applies on public projects. We price with ZIP-code-adjusted labor rates and flag trades with long lead times or thin crew availability so you can plan procurement.
Prevailing wage · ZIP-code-adjusted rates · Boston labor market · crew availabilityNarrow lots, one-way streets, and limited staging mean materials arrive just-in-time and hoisting goes into general conditions. Stormwater rules require on-site management, and many parcels have combined sewers. We quantify trench drains, detention, and pump stations, and we carry allowances for street permits, police details, and sidewalk restoration.
Stormwater management · combined sewers · street permits · police detailsSomerville's tight streets make deliveries slow and expensive. Long-lead items like switchgear, elevators, and specialty glazing need early procurement. Massachusetts sales tax applies to materials, and disposal costs for demolition debris are high. We separate material, tax, and disposal lines so you can see the true delivered cost.

The sections below are the trades where local conditions move the quantities most.
On infill lots in Somerville, the excavation quantity is rarely a clean rectangle. You are measuring around existing foundations, utility laterals, and retaining walls that stay in place. We take off bank cubic yards for cut, then apply a swell factor to get loose cubic yards for haul-off, and price disposal separately because urban dump fees and trip times are not the same as a suburban site. Dewatering is a line item, not an allowance, on sites near the Mystic River or below the Winter Hill ridge. For a full breakdown of cut, fill, and haul, see our sitework estimating services.
Wood-frame residential work in Somerville is mostly 2x6 walls and engineered floor systems, measured by linear feet of plate and count of joists and hangers. On the lab and commercial side, you are taking off structural steel by tonnage and deck by square feet, with connection counts driving the fabrication cost. Old triple-deckers bring their own problem: balloon framing, no fire blocking, and out-of-plumb walls mean the new framing takeoff has to include shoring and selective demolition. We measure framing both ways, and you can see the format in our framing estimating services.
Somerville's life-science and institutional work pushes MEP quantities well past what a typical residential takeoff would show. We count plumbing fixtures, measure pipe by diameter and linear feet, and take off ductwork by pound and by square foot of sheet metal. Lab buildings add fume hoods, process piping, and dedicated exhaust, each priced as its own assembly. Electrical takeoff runs by device count, feeder length, and panel schedule. Because these systems interact with the structural and architectural scopes, we cross-check them against the framing and envelope quantities. Our MEP estimating services page shows the divisions we cover.
Much of Somerville sits on glacial till and marine clay, so foundation takeoffs often include over-excavation and engineered fill rather than bearing directly on native soil. We measure wall footings in linear feet, spread footings by count, and slab-on-grade by square feet with a typical 5–10% waste factor. Mat slabs and pile caps appear on the larger Union Square and Assembly Row projects. Formwork is measured by contact area, not by concrete volume, which is where a lot of first-pass estimates fall short. Our concrete estimating services and foundation estimating services cover both sides of that measurement.
Somerville roofs are a mix of low-slope membrane on the larger buildings and steep-slope asphalt on the residential stock. We take off membrane by square feet including upturns and flashings, and steep-slope by roofing squares with ridge, hip, and valley lengths measured separately. Ice-and-water membrane is a real quantity here, not a footnote, because of the freeze-thaw cycles. Insulation is measured by area at each R-value, and air-barrier detailing at penetrations is counted. For a line-item view, see our roofing estimating services.
Quick check for a single element. For a full drawing set, send the plans and we measure everything, including the items calculators miss.
Typical waste: 3–5% for slabs, 5–10% for footings and walls. Truck count assumes 10 CY loads; confirm load size with your ready-mix supplier.

This walk-through shows how we get from plan dimensions to a priced concrete quantity. The dimensions are illustrative and are not taken from a specific Somerville project.
Assume a continuous wall footing 24 inches wide by 12 inches deep, running 148 linear feet around the addition. The volume per linear foot is 2.0 ft x 1.0 ft = 2.0 cubic feet. Multiply by 148 LF to get 296 cubic feet, then divide by 27 to convert to cubic yards: 296 / 27 = 10.96 CY. Add a typical 5% waste factor for over-excavation and spillage: 10.96 x 1.05 = 11.51 CY, rounded to 11.5 CY.
| Step | Calculation | Result |
|---|---|---|
| Footing cross-section | 2.0 ft x 1.0 ft | 2.0 SF |
| Volume per LF | 2.0 SF x 1.0 ft | 2.0 CF/LF |
| Total volume | 2.0 CF/LF x 148 LF | 296 CF |
| Convert to CY | 296 / 27 | 10.96 CY |
| Waste factor | 10.96 x 1.05 | 11.51 CY |
| Rounded order quantity | — | 11.5 CY |
The same logic applies to the slab-on-grade and any isolated pad footings. What changes in Somerville is the subgrade: if the geotech report calls for over-excavation and engineered fill, that volume is measured separately and priced as its own line item. Formwork is measured by contact area, which for this footing is 2 x (1.0 ft) x 148 LF = 296 SF of side forms. Rebar is taken off by bar length and count from the placing drawings, then converted to pounds using the standard weight per foot for each bar size.
If you want this level of detail across the whole package, our residential estimating services and concrete estimating services teams can put it together. We work from your plan set and return an Excel and PDF takeoff organized by CSI MasterFormat division, usually within 24–48 hours for most projects.
You get an Excel workbook and a PDF, organized by CSI MasterFormat division, with the marked-up plan set we used. Each line item shows quantity, unit, and the pricing basis. We use RSMeans data adjusted by ZIP code for material and labor, and we run takeoffs in Bluebeam Revu and PlanSwift. The package is built so you can drop it into your own bid form or send it back for revisions.
Most projects are returned in 24–48 hours. Larger lab, institutional, or multi-building packages take longer, and we will tell you the schedule before we start. Rush turnaround is available if your bid date is close. The clock starts when we have a complete plan set, specifications, and any addenda.
The residential permit figures come from the U.S. Census Bureau Building Permits Survey. They count new privately-owned residential units permitted by the city itself, not total construction activity. That means commercial, institutional, and lab projects are not reflected in those numbers, even though they are a large part of Somerville's workload.
Yes. Lab work is measured differently from residential because of fume hoods, process piping, dedicated exhaust, and clean utilities. We take those off as separate assemblies and cross-check them against the architectural and structural scopes. If your project includes a vivarium or a BSL-rated suite, tell us up front so we can carry the right divisions.
Yes, and they are common here. The tricky part is selective demolition and shoring, because balloon framing and out-of-plumb walls mean the new work has to tie into existing structure. We measure demo by area and by count, and we carry temporary shoring as its own line item rather than burying it in the framing cost.
We work across the Boston metro and the rest of Massachusetts, including Fall River, Newton, Lawrence, Framingham, Haverhill, and Waltham. Pricing is adjusted by ZIP code, so a takeoff for Somerville will not carry the same labor and material rates as one for a project further out. If your project is in one of those cities, send the plans and we will price it for that location.
Send the architectural, structural, and MEP drawings, the specifications, and any addenda or geotech reports you have. If there is a bid form or a scope narrative, include that too. The more complete the set, the fewer assumptions we have to flag. You can upload everything through our get an estimate page.
We carry temporary heat, winter protection, and cold-weather concrete measures as separate line items when the schedule runs through the heating season. In Somerville, freeze-thaw cycles also drive ice-and-water membrane and air-barrier detailing quantities. If your schedule is not set, we will show the cost both ways so you can see the difference.
Yes. Demolition is measured by area, volume, or count depending on the element, and disposal is priced separately because urban haul routes and transfer station fees differ from suburban ones. On Somerville infill sites, we also flag any suspect materials that may require testing before disposal, since that can change the handling cost.
Yes. Multi-family work is a large share of Somerville's residential permits, and we take off the full package: foundations, framing, envelope, MEP, and finishes. We organize the takeoff by building and by floor so you can phase the buyout. See our multi-family estimating services page for the divisions we cover.
Upload your drawings and specifications and we will return a CSI-organized takeoff in Excel and PDF, usually within 24–48 hours.
