# Vertical Construction

> Domain knowledge for the construction vertical (contractors, field crews) so architect and pm don't spec construction products naively. Covers the vocabulary (bid vs estimate, takeoff, retainage, change order, AIA G702/G703, lien waiver, draw schedule), the non-obvious money rules that incumbents like Procore price out of reach for small contractors, what a naive build gets wrong (no assemblies, ignored retainage, ungated sub payments), and the entities that must be modelled. Applied by architect when writing ARCH-{slug}.md and by pm when writing PLAN-{slug}.md for any of the four construction products (bid-builder, project-mgmt, subcontractor-portal, field-docs).
