We provide precise on-site as-built measurements to capture the true existing conditions of buildings and properties. Our measurement process forms the foundation for reliable drawings, informed decisions, and successful project outcomes.
As-built measurements are the process of physically measuring and documenting a structure exactly as it exists today. Unlike original construction drawings, these measurements reflect real conditions, including modifications, deviations, and site-specific details.
Our team collects accurate dimensions of architectural, structural, and building system elements to ensure all documentation is based on verified field data not assumptions
Depending on your project scope, our field measurements may include:
Interior and exterior building dimensions
Wall locations, openings, and ceiling heights
Doors, windows, and structural elements
Stairs, corridors, and circulation paths
Roof geometry and key elevation points
Mechanical, electrical, and plumbing layouts (as visible)
Site features and building context (when required)
All measurements are collected systematically to ensure consistency and reliability.




Our as-built measurement services provide accurate, field-verified data for a wide range of commercial properties. These measurements capture real-world conditions and create a reliable foundation for documentation, planning, and future development.

Clear measurements reduce uncertainty at every stage of a project. When existing conditions are documented correctly from the beginning, teams avoid delays, redesigns, and costly corrections. Our workflow is designed to collect accurate data efficiently, keeping projects moving without sacrificing quality.
No two buildings are the same. From open commercial interiors to complex, occupied spaces, our measurement approach adapts to the environment. We work carefully around ongoing operations while still capturing the level of detail required for reliable as-built documentation.
Precise measurements support better planning, coordination, and long-term use of a property. Whether the goal is renovation, expansion, space optimization, or record documentation, accurate as-built measurements provide a clear starting point you can trust.
Architects, engineers, contractors, and property managers rely on as-built measurements to move forward with certainty. Our work delivers clean, usable data that integrates smoothly into drawings, models, and future planning—without unnecessary complexity.
As-built measurements involve capturing the actual dimensions and physical conditions of a building as it exists today. This process records real-world layouts, spaces, and structural elements based on on-site verification, not original design drawings or estimates.
As-built measurements are typically required before renovations, tenant improvements, space planning, property documentation, or when existing drawings are outdated or unavailable. They are especially important when accurate information is critical for planning and coordination.
We perform as-built measurements for a wide range of properties, including office buildings, retail spaces, warehouses, hotels, mixed-use facilities, and other commercial or institutional structures.
Measurements may include room dimensions, wall locations, ceiling heights, structural elements, door and window placements, and other physical features required to accurately represent existing conditions.
Our measurements are collected using professional field tools and verified methods to ensure a high level of accuracy. Each project is carefully reviewed to minimize discrepancies and provide reliable data for future use.
Project timelines depend on the size, complexity, and accessibility of the building. Smaller spaces may be measured quickly, while larger or more complex sites may require additional time for thorough documentation.
Yes. As-built measurements provide a dependable foundation for renovations, design development, space planning, and long-term property management. They help ensure future work is based on accurate, up-to-date information.
