Before considering starting a new addition or upgrade to a building, getting the AS built information is the first thing to be done. Unfortunately, people may not understand what the drawings are or what they represent. Even when found, they can be very inaccurate; but, regrettably, most of the time the drawings can't even be located. Making replacement ones becomes the option for most people. Included below are some pointers for what to do before the project begins.
Whenever a building gets constructed there are bound to be items that get built differently than the designs specify. During the build, sometimes stuff that no one could have anticipated happens. It's extremely common to come across electrical or plumbing runs that no one knew about. Sometimes a certain material might not be available, so a substitute has to be used. It's not unusual for a change to be initiated during construction because it has a nicer look. When these things happen, there is a way to record it.
As built drawings are those that are made to represent the building the way it was actually put up. When a change is required on most commercial builds, the drawings are updated when they are made and a set of as-built is created. The modified drawings are all put together at the completion of the job so that there is a complete record. Copies may be distributed to the owner and the architect or designer. It's also necessary for these drawings to be provided to the inspector who certifies the job is done to code.
What sometimes happens though is that some alterations or additions will be wanted sometime down the road. Then the information on how things were really built will be needed to start designing the changes and they won't be able to be located. This is the time many owners will consider using a surveyor who can do laser scanning of the site. If a remodel requires inspector approval and architectural or engineering drawings, and the as-built can't be located, a survey can help reconstruct things so that new drawings can be made.
Before beginning a remodeling project where an engineer is hired to create new drawings, having accurate drawings of how the building is put together now is the first thing an owner should worry about. Barring that though, a surveyor can give the same information using state-of-the-art tools. This reconstruction can include showing changes on the original designs, a sketch and basic drawing of the site, or even 3D full site drawings that replicate what the construction drawings once showed.
