The request for information (RFI)
In typical construction, the request for information (RFI) process requires considerable resources. Issues have to be identified and effective solutions must be researched and resolved. The revised 2D digital design has to be reimported into a PDF format, printed and filed. It is now possible to minimize this RFI process altogether by making available to all members of the design and construction team the correct information derived from a building information model.
One challenge that we faced in maintaining the integrity of the BIM was staying ahead of the many changes or omissions, which occurred during design/construction process and to ensure that we always were delivering up to date “as-built” data to the client. It was not uncommon for the designers or the contractor to make changes on the job site without reflecting those changes on their drawings.
3D laser technology
Laser measuring and pointing devices guided by specialized software using the building information model data were used to check for the accurate positioning of pipes in the data center. Existing conditions can be laser scanned and converted into as built 3D models.
