Sitework and excavation
Cut and fill, shoring, retaining walls, and erosion control for Shoreline's hillside and tight infill lots.
CY · LF · TONShoreline sits just north of Seattle in King County, where infill lots, steep grades and wet winters shape every takeoff. We build line-item estimates from your plans, organized by CSI MasterFormat division, with quantities you can defend in a bid.
Shoreline costs are driven by King County labor rates, hillside excavation and shoring on infill lots, wet-weather erosion and drainage control, older housing stock needing seismic and envelope upgrades, and City of Shoreline permit review. ZIP-code-adjusted pricing keeps material and labor figures tied to this market.
Shoreline is a built-out first-ring suburb on the King County line, so most work here is remodel, addition, teardown-and-rebuild, or small multifamily infill rather than greenfield subdivision. That changes the estimate: you are pricing demolition, temporary erosion control, tight-lot staging, and often a hillside foundation rather than a flat pad. If your project touches a slope above Puget Sound or a drainage course, the sitework line items carry more risk than the framing.
We produce takeoffs from your plan set in Bluebeam Revu and PlanSwift, price them with RSMeans data adjusted to the ZIP code, and deliver Excel and PDF files organized by CSI MasterFormat division with marked-up drawings. Most projects return in 24–48 hours, and rush turnaround is available when a bid date moves. For scopes that overlap, see our residential estimating services, multi-family estimating services, and sitework estimating services. For the wider state picture, start with Washington construction estimating.
For bidders. You need quantities you can defend line by line. We break out excavation, shoring, concrete, framing, envelope and MEP by division so you can adjust labor, add a subcontractor quote, and see exactly where your bid sits before you send it.
For builders. You are pricing change orders and self-perform scopes between bigger jobs. Send a partial plan set or a sketch and we return a division-coded takeoff you can drop into your own spreadsheet without rebuilding the format.
For owners. You want a budget before you commit to a design. We price the scope from concept drawings, flag the allowances that need to be carried, and show you which divisions drive the number so you can make decisions early.

26 new housing units in 2025 (-92% vs 2024).
15 single-family · 11 multifamily (42%).
Shoreline issued 26 new privately-owned residential units in 2025, down from 324 in 2024 — a 92% decline, per the U.S. Census Bureau Building Permits Survey. Of those 26 units, 15 were single-family and 11 were multifamily, so 42% of the year's volume was attached housing. Permitted value was about $10M, or roughly $391,900 per unit. For a bidder, that means fewer jobs chasing the same crews: your labor rates are less likely to be discounted, and an estimate that undercounts a division is harder to recover on the next job. Compare the same pattern in nearby Lakewood and Redmond.
With only 26 permitted residential units, most Shoreline activity is renovation, additions, and small infill rather than tract construction. That pushes estimating toward demolition quantities, temporary protection, and tie-ins to existing framing and utilities — scopes that are easy to miss when you price from a floor plan alone. Hillside lots near the Puget Sound shoreline add shoring, retaining, and dewatering line items, and wet-season work adds erosion and sediment control. Statewide, 16,004 units were permitted across the covered cities, and Shoreline's 26 units were 0.2% of that total, ranking 25th of 25 — so this is a small, localized market where a single missed scope matters. See how the surrounding cities compare in Sammamish and Olympia.
Every takeoff is built from your drawings and specifications, coded to CSI MasterFormat divisions, and priced with ZIP-adjusted material and labor data for King County.

Shoreline's 2025 permit mix was 15 single-family units and 11 multifamily units, 42% multifamily, with $10M in permitted value. That mix drives what we price most often.
Older ranches and split-levels on tight lots are replaced with larger homes. We quantify demolition, haul-off, temporary erosion control and new foundation work from the same plan set.
Watch for: Asbestos and lead survey, debris haul-off, utility disconnect and reconnection
Adding a floor to a 1950s ranch means verifying existing framing, cutting a new stair opening and reinforcing the lower structure. We take off the tie-ins, not just the new work.

Shoreline is a built-out first-ring suburb with hillside lots and a wet marine climate. The same plan set can price differently block to block depending on slope, soils and permit path.
Shoreline permits run through the city's community and economic development department, with critical areas review when a project touches a slope, stream buffer or shoreline. The adopted code edition changes what the plan reviewer asks for, so confirm the current version with the building department before you lock your submittal dates. Allow extra time for geotechnical review on hillside lots.
City of Shoreline building department · Critical Areas Ordinance · Washington State Energy CodeMuch of Shoreline sits on glacial till and advance outwash, with softer deposits near the Sound. Till can require rock excavation and hard digging, while outwash may need over-excavation and structural fill. On slopes, expect stepped footings, deeper embedment and retaining walls. A geotechnical report is the single biggest cost driver on west-side lots.
Glacial till · Advance outwash · Geotechnical report · Stepped footingsShoreline gets roughly 37 inches of rain a year, most of it between October and April, so excavation, concrete and roofing schedules carry weather risk. Wind exposure near the Sound drives higher design pressures and more fasteners on sheathing and roofing. Envelope details, drainage plane and roof underlayment matter more here than in drier parts of the state.
Puget Sound weather · Wind exposure · Drainage plane · Roof underlaymentShoreline contractors compete with Seattle and Eastside wages, so labor rates sit above the national average. Carpenters, concrete finishers and electricians are in short supply during peak season. We price labor from current RSMeans data adjusted to the ZIP code and flag trades where you should confirm a subcontractor quote rather than rely on a bare rate.
RSMeans data · Seattle labor market · Carpenter rates · Subcontractor quotesTight lots, mature trees and steep driveways limit where you can stage materials and place a crane or pump truck. Stormwater must be managed on site, often with a flow-control facility or rain garden, and tree retention rules affect foundation layout. These items show up in sitework and concrete divisions, not in the framing takeoff.
Stormwater management · Tree retention · Site access · Flow-control facilityMost material comes from Seattle or Kent suppliers, so freight is short but yard space is scarce. Washington sales tax applies to materials and some services, and it must be carried correctly in the estimate. We price material from ZIP-code-adjusted data and show tax as a separate line so you can apply your own exemption if one applies.
Washington sales tax · Kent suppliers · Freight · Material escalationShoreline's mix of 1950s–60s single-family teardowns and newer infill means your takeoff has to handle both aging existing conditions and tight urban sites in King County.
Shoreline sits on glacial till and dense silts, so a sitework takeoff usually carries rock excavation as a separate line rather than burying it in a general 'unclassified' item. You need cut and fill quantities by station, a topsoil strip depth, and a separate line for haul-off because disposal at King County transfer stations is priced by the ton. Winter work means erosion control blankets, silt fence and a stabilized construction entrance get measured by linear foot and square foot, not lumped into a mobilization item. For the dirt side, our sitework estimating services break these out by CSI Division 31 so you can see what a change in haul distance does to the bid.
Most Shoreline residential work is wood frame over a crawlspace or slab, and the framing takeoff lives or dies on wall heights and plate counts. We measure studs by spacing and wall length, then add plates, headers, blocking and sheathing by sheet count with a typical waste factor. Older homes being remodeled often have non-standard stud spacing, so we note where the existing framing has to be furred or sistered. Roof framing gets taken off by rafter length and pitch, with valley and hip cuts shown separately. Our framing estimating services deliver this as a line-item sheet keyed to the architectural sheets.
Washington's energy code drives heat pump systems in nearly every new or substantially altered home, so the mechanical takeoff needs condenser, air handler, line set lengths, condensate routing and a dedicated circuit for each unit. Plumbing gets measured by fixture count and developed length of pipe, with the water service and sewer lateral called out separately because Shoreline has combined storm and sanitary in some older neighborhoods. Electrical rough-in is taken off by device count, home runs and panel schedule, and we flag where an existing 100-amp service has to be upgraded. Our MEP estimating services organize all three trades by division so nothing gets double-counted.
Steep lots near the Puget Sound bluffs push retaining walls into most projects, so wall footings, stem walls and slab-on-grade need separate formwork, rebar and concrete lines. We measure formwork by contact area, not by wall volume, because that is how the crews actually buy it. Rebar is taken off by bar size and lap, with dowels into existing footings called out when a remodel ties into an old foundation. Mix design matters here: freeze-thaw exposure and wet soils usually mean a specified air entrainment and a low water-cement ratio. See our concrete estimating services and foundation estimating services for the division-by-division format.
Shoreline gets roughly 37 inches of rain a year, and most of it falls between October and April, so roof assemblies here are specified with continuous underlayment and ice-and-water shield at valleys and eaves. A roofing takeoff should carry squares of field shingle, linear feet of ridge and hip, linear feet of eave and rake, and each penetration flashed separately. On low-slope sections over additions, you are usually looking at a membrane system with tapered insulation, which is measured by board foot rather than square. Our roofing estimating services handle both steep-slope and low-slope assemblies in one sheet.

This example shows how a strip footing quantity moves from plan dimensions to a purchase order. All dimensions are illustrative.
Assume a rectangular footprint 32 ft by 24 ft with a continuous perimeter footing 16 in. wide and 12 in. deep, plus one interior bearing line 24 ft long at the same size.
| Step | Calculation | Result |
|---|---|---|
| Perimeter length | 2 × (32 + 24) | 112 LF |
| Add interior bearing line | 112 + 24 | 136 LF |
| Footing cross-section | 16/12 × 12/12 | 1.333 SF |
| Net volume | 136 × 1.333 | 181.3 CF |
| Convert to cubic yards | 181.3 ÷ 27 | 6.7 CY |
| Add 8% waste and over-excavation | 6.7 × 1.08 | 7.2 CY |
The same footing also needs formwork, and formwork is measured by contact area, not volume. Two sides at 12 in. deep gives 2 × 1.0 ft × 136 LF = 272 SF of forming, plus 136 LF of keyway and 136 LF of screed. Rebar is taken off separately: four continuous #4 bars gives 4 × 136 = 544 LF, and at 0.668 lb per LF that is 363 lb, plus 10% for laps and dowels, so about 400 lb.
Two things commonly get missed on this element in Shoreline. First, if the lot slopes, the footing steps, and each step adds formwork and a vertical dowel. Second, an existing foundation tie-in needs drilled dowels and epoxy, which is a separate line from the new footing rebar. We carry both as their own rows so the bid does not absorb them silently.
When we price the concrete, we use ZIP-code-adjusted material and labor rates for the Shoreline area and show the mix design, pump or chute placement, and any Saturday pour premium as separate items. That way, if your supplier quotes a different mix or your crew places by pump, you can see exactly which line changes.
Most of the work we see in Shoreline is single-family teardown-and-rebuild, small multifamily infill, and additions or substantial remodels on 1950s–60s homes. That mix means we spend a lot of time on existing-conditions documentation, foundation tie-ins, and the energy-code-driven mechanical scope. We also estimate commercial tenant improvements along the Aurora Avenue corridor and smaller institutional projects for the school district and city. Each estimate is organized by CSI MasterFormat division so your subcontractors can bid directly from the sheet.
According to the U.S. Census Bureau Building Permits Survey, Shoreline issued 26 new privately-owned residential units in 2025, down from 324 in 2024 — a 92% drop. That is residential permits only and does not include commercial or tenant improvement work. A quieter residential pipeline usually means more contractor availability and shorter plan-review queues, but it also means subcontractors are hungrier and may sharpen bids. We do not adjust pricing for market conditions; we price from current material and labor rates and let you apply your own market factor.
The permit counts and values come from the U.S. Census Bureau's Building Permits Survey, which counts permits issued by the city itself for new privately-owned residential units only. It excludes commercial permits, tenant improvements, and any work that does not create a new residential unit. The 2025 figures show 26 total units, 15 single-family and 11 multifamily, with a permitted value of about $10M and an average value per unit of $391,900. We report them as context, not as a forecast.
Yes. Residential work is mostly wood frame, and we take it off division by division from footings through finishes. Commercial work in Shoreline tends to be smaller tenant improvements, retail, and light industrial near the transit corridor, and those estimates lean harder on Division 23, 26 and 27 because the shell is usually existing. If you are bidding a mixed-use building, we can split the estimate into residential and commercial sections so your lender or owner can see the cost breakdown clearly.
We carry temporary erosion control, stabilized construction entrances, and winter concrete protection as separate lines rather than burying them in general conditions. Roofing and exterior envelope work is sequenced with weather in mind, and we note where a dry-in package is needed before interior rough-in. We also flag dewatering allowances for excavations that will sit open through the rainy season. None of these are optional in King County, and leaving them out is one of the most common reasons a Shoreline bid comes in low.
Yes, but we will list the assumptions on the estimate so you can see what we priced and what we did not. For older Shoreline homes, we typically assume standard 16 in. on-center framing unless the plans say otherwise, and we carry an allowance for rot repair at rim joists and sill plates. We mark those allowances clearly so you can adjust them after a site walk. If you can send photos or a measured sketch, the estimate gets tighter.
We deliver Excel and PDF, organized by CSI MasterFormat division, with marked-up plan sets so you can trace every quantity back to the sheet. Most projects turn around in 24–48 hours, and rush service is available when a bid date is close. If you are working in Bluebeam Revu, PlanSwift, or pricing against RSMeans data, our sheets are built to drop into that workflow without reformatting.
We use ZIP-code-adjusted material and labor pricing, so Shoreline quantities are priced at local rates rather than a statewide average. That matters because labor in the Seattle metro runs above the state mean, and material delivery costs vary by distance from the supplier. We do not publish a single hourly rate because it changes by trade and by contract type. If you have your own labor rates or a union agreement, send them and we will price against those instead.
Yes. Once the base estimate is done, we can produce alternates — for example, swapping a slab-on-grade for a crawlspace, changing the roof from trusses to rafters, or substituting a different exterior cladding. Each alternate is priced as a delta from the base so you can see the savings and the trade-offs. We keep the alternates on separate tabs so the base bid stays clean for comparison.
Yes. We cover projects across the Puget Sound region, including Lakewood, Redmond, Sammamish, Marysville, Olympia and Richland. The estimating method is the same; what changes is the local labor rate, the sales tax, and the jurisdiction's permit and inspection requirements. If your project is in unincorporated King County or a neighboring city, tell us the address and we will price it accordingly.
Email your drawings and we will return a division-by-division estimate in Excel and PDF, usually within 24–48 hours.
