How Much Does a Formwork Takeoff Cost?

What is a formwork takeoff?

A formwork takeoff is the process of quantifying the exact amount of formwork (measured in square metres and lineal metres) required to construct a concrete structure. An estimator reads the structural engineering drawings and measures the contact area for slabs, walls, columns, stairs, and set-downs to generate a Bill of Quantities (BOQ).

How is a formwork takeoff priced?

Formwork estimating is generally priced based on the complexity and scale of the project rather than a flat hourly rate. The cost of a formwork takeoff depends on three main factors:

1. Project Scale: A single-level residential slab requires less measurement time than a multi-level commercial podium or a complex basement with deep lift pits.
2. Structural Complexity: Projects with numerous set-downs, hobs, downturns, blade columns, and curved walls take significantly longer to measure accurately than standard flat plates.
3. Detail Quality: Clear, fully detailed structural drawings allow for faster estimating. Poorly detailed drawings require the estimator to spend time cross-referencing architectural plans and making engineering judgements.

Why you shouldn't use square-metre rates for formwork

Pricing formwork using a generic square-metre rate across the whole slab is dangerous because it ignores vertical faces. A flat suspended slab might be straightforward, but edgeboards, set-downs, and lift pits require double-sided formwork, propping, and stripping. These elements are measured in lineal metres, not square metres. If an estimator only prices the floor area, the vertical formwork costs are entirely missed, leading to an underpriced tender.
