Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
Often-overlooked service interfaces
V26 connects systems that cross utility, plumbing, HVAC, envelope and metering boundaries.
Project risks and overlooked interfaces
V27 connects payment, water, envelope, ventilation and jobsite details that often create costly surprises.
Finish and service details to verify
V28 connects small details that become costly once finishes are closed.
Household safety and compliance details
V29 connects smaller risks that often fall between finishes, appliances, plumbing and local code.
