Open Shop Estimator

Exterior HOA Renovation Estimator

Build a takeoff from an open-shop exterior work library, set your own labor rates for your region and crew, and price a facade, balcony, or dry-rot renovation. Everything here is a starting point you make your own.
!
Starting points only. Set your own rate and verify before bidding. Every labor rate and catalog price below is a generic placeholder, not a real bid number. Replace each one with your own loaded cost, then confirm against a real quote before you bid any job. This tool gives you a framework, not a price.

Target gross profit drives every line price through the same engine. Overhead is taken on labor cost only to land net.
Target gross profit is your sell margin. Company overhead is taken on labor to land a rough net. Both default values are starting points, set your own.

Swipe the table sideways to see every column.
Edit any cell to set your own rate for that trade. Loaded $/hr = base + fringe + base × (tax + WC). Every rate ships as a starting point, set your real loaded cost before bidding.

Add line items

Quick-estimate from a pasted scope, search the library, or drop in a blank or sub line. Each pick lands in the takeoff pre-filled from the catalog.
Offline matcher maps each line to the closest catalog item and quantity. Anything it cannot match is listed so you add it by hand. A connected Claude turns this into full natural-language pricing.
or browse the library

Takeoff

Edit quantity and the cost field for each line. Prices recompute live through CalcEngine.computeTakeoff. Lines that carry a material grade show a cheap / standard / premium toggle under the description, swap it to see the price spread.
