Development projects are quite confusing, with numerous moving parts that should adjust accurately for the final product to transpire as planned. During the construction process, problems unavoidably emerge, and the qualified contractors prove their expertise by adjusting to essential changes from the original design plan. This is the stage where the concept of as-built drawings came into existence. Though they aren’t always obligatory, most customers will want a complete package of as-built drawings at the end of a project. Giving these drawings to the client is part of the end of the construction process, and they frequently prove beneficial in the future.

Introduction to As-built Drawing

An as-built drawing which is often referred to as record drawings is a revised drawing made and presented by a contractor after completion of the construction project. They hold any deviations made from the original drawings throughout the construction process and deliver an exact version of the structure and property as it looks upon completion. As-built representations should define the form, dimensions, magnitudes, and precise settings of all components within the range of the project. Any adjustments, whether big or small, should be involved, along with a record of agreements to go together with the modifications. Even minor information, for instance, materials and resources consumed would be documented if they vary from those specified in the initial design, with the proposed but idle resources simply obliterate, to permit future reference to the deviations that emerged during the construction process.

Techniques to create efficient As-built Drawings

As we discussed that as-built drawings should maintain the record of any deviations made from the initial plan throughout the construction process. These variations must be explained precisely in writing, with the date on which the adjustment was made. Any change from the original design ought to be detailed, whether it was in design, site, resources used, and many more.

A process must be specified ahead of time whereby various line functions share details and the as-built drawing is maintained methodically. Details, for instance, color code, the scale of the drawing, and the format of variations recorded are all significant for consistency and a worthwhile finished product. Disordered as-built drawings can puzzle future customers. Presenting a vague as-built drawing is practically as bad as presenting no as-built drawing. In California, contractors should follow the above techniques and procedures to produce efficient and useful as-built drawings.
