HVAC As-Built Drawing Services
Accurate HVAC record drawings capturing your installed system exactly as built, essential for handover, maintenance, and future modifications.
Professional HVAC As-Built Drawing Services
As-built drawings are the definitive record of how an HVAC system was actually installed, as opposed to how it was designed. During construction, systems are modified to accommodate structural constraints, site conditions, and coordination requirements. These changes must be captured in as-built drawings to provide facility managers with accurate information for maintenance, troubleshooting, and future modifications.
Yasmin Airconditioning Pvt.Ltd. produces comprehensive HVAC as-built drawing packages by conducting field surveys of installed systems and updating design or shop drawings to reflect the actual installed condition. Every duct run, pipe route, valve, damper, and access panel is verified and recorded at its true installed position.
As-built drawings are required for building handover, occupancy certificate applications, and long-term facility management. Without them, building operators spend significant time and money re-surveying systems before any modification work can begin.

Frequently asked questions
What are HVAC as-built drawings?
As-built drawings are a final record of an HVAC system exactly as it was installed, including all field modifications made during construction. They replace design drawings as the primary reference for facility management and future works.
Why are as-built drawings important for facility management?
Without as-built drawings, maintenance engineers cannot locate isolation valves, access panels, or control devices without physically tracing pipework and ductwork. This wastes time and creates safety risks during emergency shutdowns.
How are HVAC as-built drawings produced?
Our team conducts a physical field survey of the installed system, recording all deviations from design drawings. These are then used to update the original drawings in AutoCAD, producing a revised drawing set marked as 'As-Built'.
When should as-built drawings be produced?
As-built drawings should be produced immediately after commissioning and before project handover. Delaying the survey after handover risks losing field information as installation crews are demobilised.
What documents are typically included in an HVAC as-built package?
A complete HVAC as-built package includes revised duct layout drawings, piping schematics, control system diagrams, equipment schedules, valve and damper registers, and test and commissioning certificates.
Can you produce as-built drawings for an existing building where no drawings exist?
Yes. Yasmin Airconditioning Pvt.Ltd. conducts comprehensive existing-conditions surveys of buildings where no original drawings are available, producing a full set of as-built drawings from scratch.
