As-built drawings are the record of a structure as it was actually built, showing every detail of the completed work, including any modifications made during construction.
But it only holds value if it is kept updated.
Buildings evolve over time with refurbishments, upgrades, and maintenance works. Without updated drawings, what’s on paper may no longer match what’s in the structure.
Why does Updated As-Built Drawings Matter?
Accurate Planning for Refurbishment and Upgrades
Many refurbishment or upgrading projects in Malaysia face delays because existing drawings are outdated or incomplete. Updated as-builts eliminate guesswork, giving project teams confidence when cutting, coring, or installing new systems.
Reducing Risks and Costs
Outdated drawings often mean unwanted surprises such as reinforcement misplacements or undocumented modifications. These oversights lead to rework, delays, and higher costs. Updated as-built drawings provide clarity upfront, reducing both risks and expenses.
Essential for Maintenance
Whether repairing spalls, correcting slab settlement, or strengthening structural elements, updated drawings guide engineers in targeting the right areas. Without them, even simple maintenance tasks can become costly and disruptive.
Compliance and Asset Management
Updated as-built drawings also help owners stay compliant with regulations, especially for safety and inspection purposes. They support long-term asset management by ensuring facility managers have reliable information about the building’s condition and layout.
How to Update As-Built Drawings?
Relying on trial-and-error or intrusive methods would risk reinforcement strikes, unexpected voids, or structural instability to investigate the internal conditions. A non-destructive (NDT) method, such as Xradar™ concrete scanning technology, provides accurate data of reinforcement details, utilities and embedded services precise location, and even measure slab and wall thickness to confirm construction details. This saves time, prevent costly mistakes, and make refurbishment, upgrading, and maintenance projects smoother from start to finish.
