Start with roles, site rules, parking, protection plans, access hours, and emergency contacts. Review drawings together and flag long-lead materials. Confirm who orders what, who meets inspectors, and how surprises are escalated. A shared starting map prevents small confusions from snowballing into delays and resentment.
Use a centralized hub for documents, photos, selections, and approvals, whether a project app or a shared folder. Timestamp decisions and archive revisions. When the latest information is visible to everyone, errors shrink, dependencies align, and accountability becomes simple instead of emotional or adversarial.
