What are As Installed Drawings?

As installed drawings or also commonly referred to in the construction industry as record drawings, as built or as fitted drawings, are a set of service drawings that accurately show what has been installed.
When we initially issue our construction issue drawings, the MEP services shown represent what we intend to be installed once on site.
When it comes to the installation of Mechanical, Electrical and Public Health services, a number of things could occur during the installation process which means that the services installed will no longer match to what was shown during the construction stage.
From the markups you provide we can amend our construction issue drawings to accurately represent what has been installed, and re-issue an As Installed package of MEP drawings.
These as installed drawings are then used to show accurately and clearly what has been installed as well as allow any future works to be carried out by contractors.
