Sitework & excavation
Rock removal, undercut, and retaining wall quantities for Ridge and Valley hillside lots.
CY · LF · TONState College permitting runs light on new residential units, but Centre County work is steady: hillside foundations, student rental rehabs, and institutional renovations. We produce CSI-organized takeoffs with ZIP-adjusted pricing so your bid holds up.
Centre County's ridge-and-valley topography drives retaining walls, stepped footings, and deeper frost depths. Student housing near campus compresses schedules into summer. Institutional and lab work on Penn State-adjacent properties carries strict Division 01 submittal requirements. Cold winters push snow-load and freeze-thaw detailing into every exterior assembly.
State College sits in the Ridge and Valley physiographic province, where limestone and shale bedrock sit close to grade on the ridges and colluvium fills the valleys. That geology changes how you price excavation: rock removal by hoe ram or drill-and-blast, undercut and backfill, and retaining walls that show up in Division 31 before any concrete is placed. For a full breakdown of how these conditions affect bids across the Commonwealth, see our Pennsylvania construction estimating services page.
Centre County's frost depth and winter design temperatures push footings deeper than coastal PA, and the summer student-turnover window means residential rehabs near campus compress into a few months. We build takeoffs in Bluebeam Revu and PlanSwift, price them with RSMeans data adjusted to the local ZIP code, and deliver Excel and PDF files organized by CSI MasterFormat division with marked-up plan sets. Most projects return in 24–48 hours, with rush available when a bid date moves up. If you are pricing work in the region, start with a quote on our get an estimate page.
For bidders. You need quantities that survive a scope review. We mark up the plan set, list Division 31 rock and undercut line items separately, and flag missing geotech data before you commit a number.
For builders. You are framing and finishing on a schedule that ends when students arrive. We break framing, MEP rough-in, and drywall by building so your crew sequencing matches the takeoff.
For owners. You want a budget you can defend to a lender or a board. We deliver CSI-organized divisions with ZIP-adjusted material and labor pricing, so change orders trace back to a line item.

4 new housing units in 2025 (+300% vs 2024).
4 single-family · 0 multifamily (0%).
State College issued 4 new privately-owned residential units in 2025, up from 1 in 2024 — a 300% change on a very small base. All 4 were single-family, with zero multifamily, and the permitted value was $2M, or $416,300 per unit. That is 0.1% of Pennsylvania's 5,912 covered units, ranking State College 17th of 25 covered state cities. For bidders, the takeaway is not volume; it is that nearly every new unit is a custom or infill single-family home where sitework, foundation, and envelope costs dominate. Multifamily bidders should look toward Harrisburg construction estimating and Altoona construction estimating for larger unit counts.
With only 4 permitted residential units, most local construction volume is renovation, institutional, and student rental turnover rather than new subdivision work. That means interior demolition, structural repairs, MEP replacements, and envelope upgrades in older housing stock near campus. Bidders should expect occupied-building phasing, asbestos and lead paint testing in pre-1980 structures, and tight summer schedules. On the commercial side, lab and research fit-outs near campus carry Division 01 requirements that differ from standard retail work. If your backlog is industrial or warehouse, our industrial estimating services cover the process piping, racking, and slab scopes that show up along the I-99 corridor.
We price the scopes that dominate Centre County work: hillside sitework, deep frost foundations, cold-climate envelopes, and occupied renovations.

Your schedule is pinned to the August turnover. We break framing, MEP rough-in, and drywall by unit so your crews know what must be dried in before the semester starts.
Centre County limestone and shale sit close to grade, so you need rock removal, undercut, and backfill quantities separated from structural concrete before you sign a lump-sum number.
You need a budget before you close. We take off sitework, foundations, and shell from concept drawings and flag where a geotech report or stormwater approval will change the number.
You want a check on your own quantities before the bid set goes out. We return marked-up plan sets organized by CSI MasterFormat division so scope gaps are visible early.
You are budgeting roof replacement, MEP upgrades, or an addition on an occupied building, and you need ZIP-adjusted material and labor pricing you can defend to a board.
We take off plans for projects in the Borough, the surrounding townships, and the wider Centre Region, plus the corridor towns where our Pennsylvania clients build.
The 2025 permit data for State College shows 4 new privately-owned residential units, all single-family, with no multifamily units permitted. That mix means most of the work here is renovation, infill, and small commercial rather than large new apartment buildings.

Watch for: Phased occupancy, fire separation between units, and summer-only work windows.
The 4 permitted single-family units in 2025 averaged $416,300 in permitted value. We take off foundations, framing, and envelope from the plan set and price with ZIP-adjusted material and labor data.
Watch for: Rock excavation, frost-depth footings, and lot grading on tight borough lots.
Ground-floor commercial with apartments above on the downtown blocks. We separate Division 03 concrete, Division 05 structural steel, and Division 08 storefront so the shell and fit-out budgets stay distinct.
Watch for: Storefront glazing, elevator or lift scope, and separate utility metering.
Tenant fit-outs and renovations near campus with fume hoods, clean benches, and dedicated mechanical systems. We take off Division 22, 23, and 26 separately and carry the controls scope as its own line.

Two bids for the same square footage can differ by double digits here once rock, frost, and the student calendar are priced in. These are the drivers we check before we send a number.
State College Borough and the surrounding townships each run their own plan review, and the adopted edition of the IBC, IRC, and IECC can differ by municipality. Confirm the adopted code edition with the local building department before you lock a scope. Review comments on egress, fire separation, and energy compliance can add Division 01 and design fees that never appear on the drawings.
IBC · IRC · IECC · local building departmentRidge and Valley geology puts limestone and shale close to grade on the ridges and colluvium in the valleys. Excavation can turn into hoe-ram or drill-and-blast rock removal, undercut, and engineered backfill. Without a geotech report, we carry a rock allowance as a separate Division 31 line and flag it as a bid risk rather than burying it in the general conditions.
Division 31 · geotech report · rock removal · undercutCentre County frost depth pushes footings and foundation walls deeper than in southeastern Pennsylvania, which adds concrete and excavation quantity on every structure. Winter design temperatures also mean temporary heat, enclosures, and cold-weather concrete protection during the long heating season. Those costs land in Division 01 and Division 03 and change with the bid month.
frost depth · temporary heat · cold-weather concrete · Division 03State College is a small market with a limited pool of trades, and crews travel in from Altoona, Harrisburg, and the I-80 corridor. Travel time, per diem, and overtime on compressed student-turnover schedules move labor cost more than material pricing does. We price labor by trade and ZIP code rather than applying one blended rate across the whole estimate.
RSMeans data · ZIP-adjusted labor · travel time · trade ratesSloping lots, sinkhole-prone ground, and municipal stormwater rules drive detention basins, infiltration beds, and retaining walls into the site package. On tight borough lots, staging and spoils removal add cost that never shows on the plan. We take off Division 31 and Division 33 separately so the site budget is visible before the building budget.
Division 31 · Division 33 · stormwater detention · retaining wallsState College is off the main freight corridors, so structural steel, switchgear, and mechanical equipment carry longer lead times than in Philadelphia or Harrisburg. We note long-lead items in the takeoff so you can carry escalation or a procurement contingency. Local stone and concrete suppliers help on bulk materials, but specialty items still ship in.
structural steel · switchgear · lead times · escalationState College's mix of university-adjacent renovation, student housing turnover, and single-family infill means takeoffs here hinge on frost depth, karst-prone limestone, and short construction windows. Each trade carries its own local cost drivers.
Centre County's karst topography means rock excavation and sinkhole remediation can appear as bid alternates rather than base-scope line items. A proper sitework takeoff separates unclassified excavation, rock removal by cubic yard, and undercut backfill measured in tons of 2A modified stone. Stormwater management is driven by municipal MS4 requirements, so you will see infiltration beds, sand filters, and orifice plates on the plan set. For a State College project, we break out erosion and sedimentation controls by linear foot of silt fence and each inlet protection device. If your site package needs this level of detail, our sitework estimating services follow the same division-by-division format.
State College's older housing stock near downtown means renovation framing takeoffs include selective demolition, temporary shoring, and mismatched dimensional lumber. New infill construction is typically 2x6 exterior walls at 16 inches on center with engineered floor systems. We count plates, studs, headers, and blocking by linear foot, then apply a typical waste factor of 5 to 10 percent for dimensional lumber and 10 to 15 percent for sheathing. Roof trusses are quoted per piece from the supplier's layout, not by square foot. Our framing estimating services deliver a stud-by-stud count that ties to the wall schedule.
State College sees snow loads that push roof framing and shingle selection, and ice dam protection is required at eaves. A roofing takeoff here separates field shingles by square, starter course by linear foot, ridge and hip by linear foot, and underlayment by square. We also quantify ice and water shield, drip edge, and step flashing at wall intersections. Ventilation is counted per can vent or ridge vent. For steep-slope and low-slope assemblies, our roofing estimating services break out each component so your supplier quote can be checked line by line.
Frost depth in this region typically drives footings to 36 inches below grade, and the karst geology can push deeper where bedrock is shallow. Concrete takeoffs here must account for thickened edges, pier footings, and slab-on-grade with vapor barrier and rigid insulation. We measure formwork by square foot of contact area, not by the lineal foot of wall, because stepped footings on sloping lots change the math. Rebar is taken off by bar size and lap splice, then converted to tons. For foundation packages, our foundation estimating services include anchor bolt templates and embeds that are often missed on residential plans.
Pennsylvania's adopted Uniform Construction Code references the International Residential Code and International Plumbing Code, but State College's plan reviews may add local amendments, so confirm the adopted edition with the local building department. MEP takeoffs here must account for basement mechanical rooms, high-efficiency condensing furnaces, and PVC DWV systems with cleanouts at required intervals. We measure supply and return ductwork by pound of sheet metal and count registers, diffusers, and flex runs separately. Electrical takeoffs include homeruns by circuit, device boxes, and panel schedules. Our MEP estimating services cover mechanical, electrical, and plumbing in one coordinated package.
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 example shows how we calculate concrete volume for a continuous footing at a typical 36-inch frost depth. Dimensions are illustrative and do not represent a specific plan.
Assume a rectangular footprint 32 feet by 48 feet with a center bearing wall running the 48-foot direction. The footing is 16 inches wide by 12 inches thick, bearing 36 inches below grade. We calculate perimeter and interior length separately.
| Step | Calculation | Quantity | Unit |
|---|---|---|---|
| Exterior footing length | 2 × (32 + 48) | 160 | LF |
| Interior footing length | 48 | 48 | LF |
| Total footing length | 160 + 48 | 208 | LF |
| Cross-section area | (16/12) × (12/12) | 1.33 | SF |
| Net concrete volume | 208 × 1.33 | 277 | CF |
| Convert to cubic yards | 277 ÷ 27 | 10.3 | CY |
| Waste factor (typical 5%) | 10.3 × 1.05 | 10.8 | CY |
| Order quantity (round up) | — | 11 | CY |
We then extend the same logic to the foundation walls. If the wall is 8 inches thick and 36 inches high, the volume is 208 LF × (8/12) × 3 = 416 CF, or 15.4 CY, plus 5 percent waste for a total of about 16.2 CY. Rebar is taken off separately by bar size and lap splice, then converted to tons. This level of detail prevents the common gap where footing concrete is ordered from a square-foot allowance instead of measured geometry. For a full foundation package, our foundation estimating services include formwork, rebar, anchor bolts, and waterproofing. If you have a State College project with similar frost-depth conditions, send us the plan set for a line-by-line takeoff.
The permit figures we reference come from the U.S. Census Bureau's Building Permits Survey. That survey counts new privately-owned residential units permitted by the city itself. It does not include commercial, industrial, or institutional permits, and it does not capture renovation or addition permits. For State College, the 2025 survey year shows 4 new residential units, all single-family, with a total permitted value of $2 million. Use these numbers as a directional indicator of residential activity, not as a full picture of construction volume.
Yes. Centre County sits in a limestone valley where solution channels and sinkholes are possible. A takeoff should separate rock excavation, over-excavation and backfill, and potential grouting from the base footing and wall quantities. We recommend carrying a unit-price line for rock removal by cubic yard rather than a lump-sum allowance, because the quantity can swing widely between adjacent lots. Your geotechnical report will indicate whether test borings encountered pinnacles or voids. Confirm any site-specific requirements with the local building department before finalizing your bid.
The adopted building code in Pennsylvania typically requires footings to bear below the frost line, which in this region is commonly taken as 36 inches below finished grade. That depth drives footing width and concrete volume. Your project's geotechnical report may specify a different depth if soil conditions warrant. We take off footings by measured length and cross-section, then apply a typical waste factor. Always verify the frost depth requirement with the local building department, since the adopted code edition and any local amendments control.
We apply waste factors by material category, not as a single blanket percentage. Typical ranges we use are 5 to 10 percent for dimensional lumber, 10 to 15 percent for sheet goods like plywood and drywall, 5 percent for concrete, and 2 to 5 percent for rebar. These are industry-typical ranges, not code requirements. For State College projects, we may adjust upward for complex roof geometries or renovation work where existing conditions create more cuts. The waste factor is shown as a separate line so you can see the net quantity and the allowance.
We produce takeoffs organized by CSI MasterFormat divisions, typically covering Division 02 through Division 26 for a residential or light commercial project. That includes existing conditions, concrete, masonry, metals, wood framing, thermal and moisture protection, doors and windows, finishes, specialties, equipment, and the MEP divisions. We can also extend into Division 31 and 33 for sitework and utilities. The output is delivered in Excel and PDF with marked-up plan sets, so you can trace every quantity back to the drawing.
Yes. Renovation takeoffs near downtown and the university-adjacent neighborhoods require selective demolition quantities, temporary shoring, and allowances for unknown existing conditions. We measure demolition by square foot of wall or floor removed, count door and window openings, and separate new framing from existing to remain. We also flag where structural modifications may trigger a plan review. Because older homes often have non-standard framing, we recommend a site visit or as-built measurements if available. Our residential estimating services cover both new construction and renovation.
Pennsylvania's adopted code includes ground snow load maps, and State College falls in a zone that typically requires design for significant snow. For roofing takeoffs, that means we check the roof framing schedule for increased rafter or truss sizes, and we include ice dam protection at eaves as a separate line item. Shingle quantities are measured by the square, with starter course, ridge, hip, and valley flashing broken out. We also count ventilation per the plan. Confirm the adopted code edition and any local amendments with the local building department.
Most projects are delivered in 24 to 48 hours. Rush service is available if you have a bid deadline sooner than that. The turnaround depends on the size and complexity of the plan set, and on whether we need to request clarifications. For a typical single-family house or small commercial fit-out, we can usually return a full takeoff within two business days. Larger multi-family or industrial projects may take longer, and we will confirm the schedule when we receive your plans.
Yes. We provide construction estimating services across Pennsylvania, including Harrisburg, Altoona, York, Wilkes-Barre, Chester, and Norristown. If your project is in one of those areas, the same ZIP-code-adjusted material and labor pricing applies. We also cover the broader state with our Pennsylvania construction estimating services. For State College specifically, we understand the local labor market and material logistics that affect pricing. Send your plans and we will confirm coverage and turnaround.
We deliver Excel workbooks and PDF reports, organized by CSI MasterFormat division. Each takeoff includes a marked-up plan set so you can see exactly where quantities were measured. We use Bluebeam Revu, PlanSwift, and RSMeans data for pricing. The Excel file is structured so you can sort by division, trade, or cost code, and adjust waste factors or unit costs. If you need a specific format for your estimating software, let us know when you send the plans.
Email your plan set and we will return a division-by-division takeoff with marked-up drawings, typically within 24 to 48 hours.
