An as-built survey documents the actual, final conditions of a completed construction project by measuring building locations, dimensions, and elevations against original design plans. These surveys capture structural elements, utilities, site improvements, and landscape features as they were actually constructed, not as originally designed. As-built surveys provide critical documentation for project closeout requirements, building permits, compliance verification, and future renovation planning by creating accurate records of final construction conditions.

Keystone Associates provides as-built surveys to support project closeout, regulatory compliance, and future development planning. These surveys document completed construction projects with precision measurements that verify actual conditions against design specifications.

Our process begins with review of original design plans, construction documents, and project specifications to understand intended versus actual construction. We conduct comprehensive field measurements of all completed structures, utilities, site improvements, and landscape features, documenting any deviations from original plans with survey-grade accuracy. Final deliverables include detailed as-built drawings and digital CAD files delivered via email, formatted to meet contractor, architect, and regulatory agency specifications for project closeout and compliance documentation.
