Estimating Monolithic Slabs

Use the BidMagic construction estimating software to estimate concrete and masonry foundation costs.

Monolithic Slab Estimating

This foundation includes a slab and a grade beam/footing, both poured at the same time.

On the Foundation Dimensions card, enter into Footings & Grade Beams the measurements of the 'extra' area where the slab is thickened. The slab itself is entered into Floor Slabs.

EXAMPLE: If you have a 4" slab that is thickened to 12" for a 2 foot band around the perimeter, enter the grade beam/footing as 8" thick and 24" wide.

In Specifications, choose a monolithic footing under Concrete Walls on the Concrete card, and a slab under Concrete Slabs. You may also need to include drainage, gravel, vapor barrier or foam insulation beneath the slab, and perimeter insulation.

Multi-Story with Slab

In a two story building with a floor slab downstairs and a framed floor upstairs, enter the slab and foundation normally, as described in one of the preceding sections.

When entering the floor framing on the Wall & Roof Framing card, use the second floor area as a quantity, rather than the full floor framing area.
