What is the importance of as-built drawings and as-built models?

When it comes to design build projects, one of the most paramount thing is the development of as-built drawings and models which can be used for multiple purposes in future. In other words, today it has become important and necessary for contractors to supply effective as-built drawings and models to owners which can assist them in enriching their knowledge about the whole process. Both as-built CAD drawing Services and models contain detailed information on construction process and the kind of modifications that have been made in the design from time to time.

Generally what happens, when the construction contract is signed between contractors and building owners it’s clarified that in the end when the final product will be delivered to owners it will be accompanied with as built drawings and models.

So wherever a modification is done in the design it is effectively included in as-built drawings that means not even single information is left unrecorded by AEC professionals concerning the project in question. These crucial construction assets which are provided by contractors to owners are utilized by facility managers and AEC professionals during building’s maintenance.

When it comes to renovation and refurbishment of a building, these as-built drawings and models become the biggest source of information to AEC firms. Information that is highly important for renovation of the building can be effectively extracted by architects, engineers and contractors from these final construction assets. That means architects and engineers can get the information on materials, design and resources that were utilized during building’s construction which can help them in understanding the technicalities of renovation process effectively. Information related to dimensions, sizing, and fabrication etc. is clearly included in as-built drawings hence maintenance and renovation of a building can be effectively carried out by AEC professionals with their assistance.

Hence for cost effective renovation, refurbishment and redevelopment of a building both as-built drawings and models are necessary. Apart from that these critical as-built construction assets can be utilized for claiming insurance if the building disintegrates or collapses because of natural calamities.
