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.
  • Renovation: The remodeling contractor or GC faces fundamentally different conditions than in new construction. Work happens within an existing structure with Concealed conditions, often in an occupied home requiring phased sequencing and temporary protections. Pricing models include higher contingencies; contracts may use GMP with discovery allowances or cost-plus rather than fixed lump sum. The contractor must be EPA RRP-certified for pre-1978 homes, coordinate with abatement specialists, and manage code-compliance triggers under the IEBC. In Design-build delivery — more common in renovation — the contractor also leads design. Crews tend to be smaller and more multi-skilled than in new construction. NARI Standards of Practice provide the procedural framework for remodeling contractors.
