Builder and general contractor
Kind: Who assembles the execution machine
Tag: estimate, buyout, schedule, field control
Role in the system
The builder or GC turns a document package into a sequence of real work. This actor is the main scheduler, coordinator, cost-and-time gatekeeper, and the party that holds the field together while trade contractors, vendors, and inspectors interact around the house.
Delivery-model nuance
- Built for sale - production: Often both sponsor and constructor: land, plan package, procurement, trades, schedule, warranty.
- Custom - owner’s land: Often enters after some design work, though preconstruction collaboration can start earlier.
