Concrete Estimating Services Volume, Rebar, Formwork and Placement

Concrete estimates for concrete subcontractors, general contractors and civil builders. Volumes come from the structural sections rather than from plan area, rebar is weighed off the schedules, and formwork is priced by square foot of contact area with the reuse assumption written down.

What a Concrete Estimate Covers

Formwork and rebar are usually where a concrete bid is won or lost, so both are measured properly instead of carried as a percentage of the pour.

Foundations

Everything below the slab, measured from the sections.

  • Spread and continuous footings
  • Grade beams and pile caps
  • Foundation walls and stem walls
  • Excavation and backfill interface
Slabs

On grade and elevated, with the finishes that go with them.

  • Slab on grade by thickness
  • Elevated slabs and topping slabs
  • Vapour barrier and sub-base
  • Metal deck interface quantities
Vertical Concrete

Walls, columns and beams by section and height.

  • Walls by thickness and height
  • Columns by section and lift
  • Beams and shear walls
  • Stairs, ramps and landings
Reinforcing

Rebar weighed off the schedules, not estimated per cubic yard.

  • Rebar weight by bar size
  • Bar schedules and bend lists
  • Welded wire and fibre reinforcement
  • Dowels, chairs and accessories
Formwork

Square feet of contact area with a stated reuse count.

  • SFCA by element type
  • Form reuse and stripping cycles
  • Shoring and reshoring
  • Edge forms, bulkheads and blockouts
Placement & Finishing

Labor, pumping and the finish the spec actually calls for.

  • Pump, crane or buggy placement
  • Finish type and flatness class
  • Curing, sealing and joint sawing
  • Embeds, anchor bolts and testing
Deliverables

What You Get Back

Three files, every time — the numbers, the evidence behind them, and what we assumed to get there.

Priced Estimate

A line-item estimate in Excel or CSV, priced off your own cost library or a regional benchmark database, with material, labor, equipment and subcontract split out.

  • Line items grouped by CSI division
  • Material, labor and equipment split
  • Markup, overhead and profit applied
  • Excel, CSV or BidcoreAI project
Marked-Up Drawing Set

The measured drawing set comes back with every quantity traced on the sheet it came from, so your own reviewer can check a number without re-measuring it.

  • Colour-coded measurement overlays
  • Sheet and detail references
  • Scale and calibration recorded
  • Searchable PDF
Assumptions & Exclusions

A written basis of estimate: what was included, what was excluded, which allowances were carried, and the open questions worth issuing as an RFI before the bid goes out.

  • Basis of estimate memo
  • Inclusions and exclusions list
  • Allowances and contingencies
  • Suggested RFI list

How It Works

From Drawing Set to Bid-Ready

1
Send the drawings
Upload the plan set, specifications and any addenda through the request form — or paste a Drive, Dropbox or WeTransfer link if the set is large.
2
Scope analysed by the platform agent, then reviewed manually
The BidcoreAI agent reads every sheet, schedule and specification section and returns the full scope. An estimator then reviews it line by line against the drawings, so nothing is carried on the agent alone and nothing in the set gets missed. You get a fixed quote and a delivery date before any work starts.
3
Measured and priced
Quantities are measured in the BidcoreAI takeoff workspace, then priced against your cost library or a regional benchmark database.
4
Delivered and reviewed
You get the estimate, the marked-up set and the basis of estimate — plus a call to walk the numbers if you want one.
