The first way is to use the Geophysical surveying technologies; this procedure will take place if the reliability of the data is very poor due to the non standardization of the generated as-built drawings
, or due to the non network completeness and oldness.
To retrieve as-built drawings
, employees had to search for the job number by looking at old paper maps or card catalogs.
One of the reasons I started this business is that every project I've known has been delayed or affected in some way by a lack of accurate as-built drawings
. This causes delays, unpredictable costs, and contract variations.
A survey of the installation site is essential to verify the accuracy of as-built drawings
to reduce the risk of unforeseen conditions and costly change orders that affect project cost and schedule.
A greater degree of accuracy and quality control was achieved by scanning the existing facility rather than relying on limited as-built drawings
of questionable accuracy.
From planning to as-built drawings
, all directional data is documented and recorded using the DataTraX (DTX).
Information from site visits, DOE-2 manuals, as-built drawings
, and measured energy and operation data were used to create a DOE-2 input file for the calibrated as-built simulation.
The new technology offers significant possibilities for the real estate market as well as structural engineers, architects, facade restoration firms and others who produce as-built drawings
Another recommendation: Ensure that the installing contractor turns over as-built drawings
at the end of any project.
To obtain final approval on a construction project, contractors are required to submit their as-built drawings
in one of several computer-aided design (CAD) formats, exactly in compliance with the CCWA As-Built CAD standards.
"After all," he reasoned, "the township is requiring that the contractor provide as-built drawings
, so they'll have to do it right." When we delivered all of the permits and plans required to bid and build the project, he paid his bill and left--and we heard nothing from him or about the project for almost a year.
Accurate as-built drawings
can substantially reduce the cost of retrofit construction.
