As built drawings defined.
As built drawings procedure.
The drawings that are first completed for a planned construction project are not the ones that are needed once the project is finished.
Instead the contractor needs to submit the as built drawings.
Record drawings formally known as as builts are the official record of the final engineering plans for all construction projects administered by adot.
They are the original design drawings revised to reflect any changes made in the field such as design changes issued by variations change order modifications component relocations required for coordination rerouting of distribution systems shop drawing changes extra works etc as such the as built drawings allow a comparison between the initial design and the final product and provide.
The as built drawings should document all changes made to the specifications and design made during the building process and they should show the exact dimensions and actual locations.
For example future renovations or building additions will be easier more efficient and less troublesome for future contractors because they can retrieve the as built documents for crucial information like pipelines duct routing electrical circuits and systems etc.
They are the field redlines and changes made during construction which are recorded on the original as bid plan set showing any changes or modifications made to the project during construction.
This procedure describes how to prepare as built drawings of a structure after completion of construction work.
The as built drawings comprise a revised set of construction drawings that are submitted by the contractor when a complete project or individual stages of a project are completed.
As built drawings are required in almost every project and it is a common practice for future reference.
The major purpose of an as built drawing is to record any modification made during the building process that deviates from the original design.
Preparations of as built drawings shall be based on the approved redline markup drawings.
As built drawings are prepared by the bridge project contractor checked and accepted by the respective engineer to the contract.
As built title block is required to be added.
Recording as built and taking care of red line drawings during construction can be a hurdle to clear before getting the final payment or releasing the retainage.
As built drawings should be prepared for all repaired and new structures on the rhd road network.
Details such as a color code drawing scale and the format of changes logged are all important for the sake of consistency and a useful final product.
As part of qa procedures it is imperative to maintain the log of redline markup and as built drawings.
As built drawings are drawing records from which future changes are based on.
A procedure must be specified in advance whereby different line functions share information and the as built drawing is systematically maintained.
