Estimate the fit-out with room for the unknowns
A commercial fit-out has surprises above the ceiling grid and behind the walls. A good estimate prices the work and leaves room for what you cannot see yet.
Break the bid into the systems you install. Service and panel. Branch circuits and devices. Lighting. Each section shows a subtotal, so the GC or owner reads it by system instead of as one number.
Turn on a contingency line for the unknowns. On a fit-out, that buffer is the difference between a fair bid and a money-loser. List what is by others, like data terminations, so the scope is clear.
Download the branded PDF and send it. If you do not want your unit rates on the page, turn off line prices and show scope and totals only.
Commercial Electrical Estimate Builder questions
Is this really free?
Yes. No email, no signup, and nothing you type leaves your browser.
Can I add a contingency for a fit-out?
Yes. Turn on the contingency line and set a percent. It adds a buffer to the subtotal for the unknowns on a commercial job.
Can I break it out by system?
Yes. Group the work into service and panel, branch circuits and devices, and lighting. Each section gets its own subtotal.
Can I change the checklist?
Everything is editable: items, sections, order, and printed columns. The starter list is a starting point, not a cage.
