Commercial estimating

Commercial construction estimating

Ground-up commercial, tenant improvement, retail rollouts, pre-engineered metal buildings and light industrial shells.

How we approach it

Offices, retail & warehouses

Commercial bids turn on three things: general conditions, the structural package, and where MEP responsibility actually starts and stops. Those get the most review time.

On pre-engineered buildings the manufacturer’s supplied package is separated from field-installed scope, because that boundary is where double-counting and gaps both live. On tenant improvement work, pricing starts from the landlord’s real base-build condition rather than an assumed bare shell.

Common omissions we look for

General conditions under-run on long programmes, PEMB scope counted twice, and design-intent MEP priced as though it were coordinated.

Commercial questions

What contractors ask us first

The manufacturer supplied package is separated from field-installed scope explicitly, because that boundary is where double-counting and gaps both live. You see exactly what is supply and what is erection.

Yes. Pricing starts from the landlord base-build condition described in the lease or drawings rather than an assumed bare shell, which is a common and expensive assumption.

Yes, modelled against the actual programme duration rather than a percentage. General conditions under-run on long programmes is one of the more damaging errors in commercial bidding.
