What You Should Know About As-Built Drawings
Does your assembly or structure resemble your engineering drawings? If you've realized some discrepancies between your drawings and your building, you probably need to request as-built drawings.
As-built drawings are a little like the final draft of a paper and include every change the structure has undergone throughout planning and execution. They provide details of the entire proposal.

Why As-Built Drawings are Essential to the Project
Sometimes called "record documents," as-built drawings are created from red-lined drafts submitted by the contractor and subcontractors. They're one of the most important pieces of O&M documentation.
Managing these documents can be challenging, but new construction management software is becoming a popular way to keep on top of it. However you manage it, it's essential that you do for a number of reasons, namely:
As-built drawings provide crucial information concerning process safety management and process hazard analysis requirements for the structure.
They show where equipment shut-off valve locations are so that you can easily find them in the event of an emergency.
Because as-built drawings show where every component of the structure is located, managers will know where to anticipate safety hazards and can set-up appropriate perimeters and signage.
Renovations, Retrofits, and Maintenance
Since they show where every pipe, duct, and wire is located, future renovations or, heaven-forbid, retrofits, will be executed more efficiently.
Without the drawings, when work needs to be done on the space someone will need to hunt down the original engineering documents that give dimensions of each piece of equipment in each area--or measure them.
All new designs will begin with a look at the as-built drawings if you have them. Good renditions will prevent needless reworking of drawings for renovations or any other major changes in the future.
The drawings must be regularly updated to incorporate even the most minute alteration. Remember never to delete information when modifying the as-built drawings--always line or X through what you would like to delete to avoid future confusion.
As the drawings are updated, note the revision date and revision number.
Remember to note changes in the index for ease of use.
Maintenance and Operations
Document, document, document!
As-built drawings assist in efficiently maintaining and operating the structure because they provide a clearly documented history of the space.
The building's mechanical, structural, electrical, and plumbing systems will be fully documented with these drawings, making maintenance and repairs on them much faster.
Without these drawings, surveying the space and determining which components need maintenance is much more time-consuming, and therefore costly.
One Step Further
Regular 2-D as-built drawings will cover the bases, but if you want to take it a step further, new technology exists to create as-built intelligent 3D models.
A 3-D model can be linked to CMMS databases and linked to a single application which provides all of the above benefits and more.
Don't Have As-Built Drawings?
If you don't have any for your space, you can still commission the creation of them. With a thorough walk-through of the building, they can be created even years after completion.
