BidAccurate's foundation estimating services cover the below-grade scope for general contractors, foundation and concrete subs, suppliers, and developers across the US. We pull from the structural and civil sets, the architectural wall sections, the spec, and the geotechnical report when you have one.
On most jobs the foundation plan alone won't get you to a number. Footing steps show up in the sections, over-excavation in the soils report, and waterproofing in Division 07. We measure footings, grade beams, stem walls, piers, mats, and deep foundation elements, then pick up the excavation, base, backfill, drainage, and reinforcing that go with them, as far as your contract scope reaches.
What's Included in Our Foundation Estimating Services
Your scope split decides what we measure. If the sitework sub carries mass excavation and you carry footing excavation, the takeoff follows that line. Here's what we usually cover.
Shallow Foundation Systems
Each footing is listed by mark, size, and top-of-footing elevation. Steps and depth changes stay with the footing they belong to.
Continuous and isolated spread footings
Strip footings, grade beams, and combined footings
Mat, raft, and thickened-slab foundations
Foundation walls, stem walls, piers, and pedestals
Deep Foundations and Ground Support
Piles and drilled shafts are measured the way your spec pays for them, whether that's a count, a depth, or a length below cutoff. Specialty-sub work stays apart from what you self-perform.
Driven piles, helical piles, micropiles, and drilled piers
Drilled shafts, caissons, pile caps, and helical pile brackets
Rock sockets, casings, reinforcement cages, and concrete fill
Testing, cutoffs, splices, mobilization, and specialty equipment allowances
Concrete, Reinforcement, and Formwork
Footing concrete, forms, and rebar are reported together, so a grade beam's yardage, contact area, and bar weight can be checked on one row.
Concrete by cubic yard, element, strength, or mix designation
Reinforcing bars by size, length, weight, or bar mark
Dowels, welded wire reinforcement, chairs, couplers, and supports
Form contact area, edge forms, bulkheads, keyways, and blockouts
Excavation, Base, and Moisture Protection
Trade splits get fuzzy here. We measure dig, base, backfill, and waterproofing when they're yours and carry them as allowances when the documents leave it open.
Footing excavation, trenching, over-excavation, and backfill
Granular base, mud slabs, compaction, and soil-treatment allowances
Dampproofing, waterproofing, protection board, and drainage composites
Vapor retarders, underslab and perimeter insulation, and footing drains
Labor, Equipment, and Accessories
For a priced estimate, labor and equipment are broken out by activity. Dewatering and shoring get their own lines because site conditions drive them so heavily.
Layout, forming, reinforcing placement, pouring, vibrating, and stripping
Pumps, cranes, drilling or pile-driving equipment, shoring, and dewatering
Anchor rods, embeds, sleeves, waterstops, joints, and sealants
Curing, testing coordination, access, cleanup, winter conditions, and protection
Measurement, Allowances, and Reporting
Units match how each item is bought or installed. Assumptions about soil and trade limits are written out.
Cubic yards (CY) for concrete, excavation, base, and backfill
Square feet (SF) for formwork, membranes, insulation, and slab areas
Linear feet (LF) for walls, beams, joints, drainage, and continuous footings
Pounds or tons for rebar; each (EA) or linear feet for piles and accessories
Foundation Bid Coming Due?
Send the current plans, spec, soils report, addenda, location, and bid date. We'll review the below-grade scope and confirm what we'll measure and what you'll receive.
Foundation work is spread across the structural and civil sets, the wall sections, the spec, and the geotech report. We pull them together and note where your scope ends and the sitework or waterproofing sub's begins.
Less Time Tracing Footings
Tracing stepped footings and pile layouts by hand is slow work. We do that part so your team can price.
Ready for Sub and Supplier Quotes
Element-by-element concrete, rebar, and waterproofing quantities drop straight into quote requests to your ready-mix plant, rebar fabricator, and pile contractor.
Keyways and Dowels Accounted For
Keyways, slab dowels, waterstops at wall joints, footing drains, and pile testing are common misses. We check for each one.
Plans Marked by Element
Marked-up foundation plans, plus a drawing reference on every line of the workbook.
Flexible Cost Inputs
We can price with your ready-mix and rebar quotes, pile subcontractor numbers, crew rates, equipment costs, and cost codes.
Soil conditions, groundwater, installation method, and who owns the dig all move a foundation price. We put each of those decisions in the estimate where you can see it, instead of folding them into one unit price.
01
Geotech Report in the Review
When a soils report is in the bid set, we read it for over-excavation, bearing elevation notes, and groundwater that change the quantities.
02
Shallow and Deep Kept Apart
Footings and walls sit in one group, piles and piers in another, so a specialty sub's quote drops right in.
03
Dirt Next to the Concrete
Excavation, base, and backfill are listed beside the footing they serve. That makes it easy to confirm each footing has a matching dig.
04
A Paper Trail for Every Line
Marked plans, sheet references, and an assumption list let your estimator check our calls quickly.
05
Set Up Around Your Bid Schedule
We set up the Excel and PDF files around your bid schedule, cost codes, or supplier list at intake.
06
Addenda Compared to the Prior Set
If an addendum deepens a footing or swaps spread footings for drilled piers, we compare sets and update what changed.
Our Foundation Takeoff and Estimating Process
The path from your document upload to a below-grade takeoff your team can check before pricing.
1
Send the Foundation Documents
Include the structural and civil plans, the geotechnical report if there is one, the spec, addenda, bid form, location, and bid date.
2
Settle the Trade Split
First we confirm who digs, who waterproofs, and who carries the piles. Then we agree on units, alternates, pricing inputs, and report format.
3
Measure and Classify
Footings, walls, piers, piles, forms, rebar, excavation, and moisture protection are measured and sorted by the agreed breakdown.
4
Check Against Sections and Soils Data
Plan quantities are checked against sections, footing schedules, and the geotech recommendations. Anything that doesn't line up goes on the assumption log.
5
Deliver the Estimate Package
You receive Excel or PDF reports with color-coded plan markups. Material, labor, and equipment are priced when you ask for it.

Related Foundation Trades and Services
Foundation work hands off to concrete above grade, rebar inside it, and sitework around it.
What documents do you need for a foundation estimate?
Foundation plans, sections, and footing schedules, the structural, architectural, and civil sets, the spec, addenda, bid form, location, and bid date. Send the geotechnical report if there is one, since it often changes excavation and footing depth. For a priced estimate, include any supplier or pile-sub quotes, labor rates, equipment costs, and cost codes.
What's in a foundation takeoff?
Spread and continuous footings, grade beams, foundation and stem walls, piers, pedestals, mats, and deep foundations like drilled shafts, caissons, piles, and pile caps. With those come the concrete, forms, rebar, excavation, base, backfill, waterproofing, drainage, insulation, anchor rods, and embeds that fall in your scope. Where your scope stops depends on the trade split in the bid documents.
Is a foundation takeoff the same as a foundation estimate?
No. The takeoff counts and measures: yards of footing concrete, LF of wall, number of piles. The estimate prices those quantities with material costs, labor production and rates, equipment, specialty-sub quotes, and whatever overhead, profit, tax, or contingency you want included.
How do you measure and report foundation quantities?
Concrete, excavation, base, and backfill in cubic yards. Forms, membranes, and insulation in square feet. Walls, grade beams, continuous footings, and footing drains in linear feet. Rebar goes in pounds or tons, and piles, anchors, and embeds by each or by length, depending on how the spec pays for them. We can group the report by building, area, element, elevation, or cost code.
What file formats does the foundation estimate come in?
An Excel workbook, PDF reports, a scope and assumption log, and color-coded PDF plan markups. If you want it organized around your bid form, cost codes, or supplier list, tell us before we start.
Can you revise the foundation estimate after an addendum?
Yes. Send the revised drawings, schedules, spec sections, and addendum. We compare the affected footings, walls, piers, or piles with the prior set and update quantities, pricing, and scope notes. Timing depends on how much changed and how clearly the revision is shown.
Can you price with my concrete, rebar, pile, and labor numbers?
Yes. We can use your ready-mix and rebar quotes, pile or drilled-shaft proposals, crew rates, production assumptions, equipment costs, freight, testing allowances, waste factors, and markups.
What affects turnaround on a foundation estimate?
Job size, foundation type, how much the footings step and change, deep foundation work, drawing completeness, whether a soils report is available, the level of breakdown you need, alternates, addenda, and your bid date. We review the set first and then confirm a delivery date.
