Accountability becomes visible at the interface: not in the scope description, but in the live record of who owns the next action, what evidence is required, and when the handover must occur.
Day 91: an effective interface register connects adjacent trades, design packages, approvals, inspection responsibility, sequencing requirements and close-out evidence in one controlled view.
This is not a static spreadsheet. It is a live governance instrument that exposes dependency risk before it becomes rework, delay or a liability vacuum. Each interface should identify the accountable party, prerequisite information, inspection hold point, required evidence and status of completion.
The critical question is not simply, “Who is responsible?” It is:
1. What must be available before the trade can proceed?
2. Which approval or inspection controls the release?
3. Who verifies the interface before it is concealed?
4. What evidence closes the item beyond reasonable dispute?
Without this discipline, adjacent trades operate in isolation; responsibility migrates between packages, sequencing breaks down, and close-out becomes a retrospective search for proof.
With it, The Building Vault records the chain of accountability as the project moves from design intent to verified installation.
If your project interfaces are being managed through memory, email chains or assumptions, the risk is already active. Contact Shoal Bay Projects to establish a forensic, evidence-backed control framework.
