When it comes to completing a mechanical project, whether it’s HVAC or process piping systems, accurate Mechanical As Built Drawings are essential. In commercial and government construction sectors, the demand for professionally prepared Mechanical As Builts has never been higher.

But what exactly are Mechanical As Built Drawings? Why are they so important? And what should builders, contractors and consultants expect from a quality Mechanical As Built service?

What Are Mechanical As Built Drawings?

Mechanical As Built Drawings are the final set of drawings that reflect the true, installed condition of mechanical systems at project completion. Unlike construction drawings, which show how systems are intended to be built, Mechanical As Builts document how they were actually installed, including any site variations, relocations, or modifications made during construction.

These drawings often cover systems such as:

• Heating, Ventilation, and Air Conditioning (HVAC)
• Mechanical ventilation
• Chillers, boilers and cooling towers
• Process piping
• Tundish and condensate drainage systems

They form a crucial part of the handover documentation required by builders and are often tied to warranties, certifications and maintenance procedures.

Why Mechanical As Builts Are Critical

Mechanical As Built Drawings are often mandatory for:

• Project finalisation and occupancy permits
• Operation and maintenance manuals (O&Ms)
• Safety compliance and audits
• Asset management and future renovations

Projects in sectors such as healthcare, education, government, mining and commercial construction place particularly high emphasis on Mechanical As Built Drawing accuracy before granting certification of occupancy or compliance.
