Manage tenant-driven changes within the contractual change-control framework - helping define the request, route it through the proper technical and commercial review paths, capture high-level cost, schedule, scope, and risk impacts, and drive clear owner/tenant decision-making. Develop and maintain the integrated delivery program - including design decision logs, RFIs, change logs, action items, risks, open issues, milestone trackers, and tenant-facing status materials - as the single source of truth for the tenant relationship during delivery.
