Kuidas muudab mudelprojekteerimine teraskonstruktsioonide valmistamist ja ehitamist
The detailer develops preliminary shop
drawings, used for ordering steel from the mill for delivery to the fabricator. Thus the
prime contractor assumes the risk for availability and delivery of steel to meet the
contract schedule. This highly linear process can add six to eight weeks to the project
schedule for a complex structure (Whited & Gatti, 2007).
During construction, problems tend to amplify when the wrong steel arrives at the wrong
time on the jobsite due to poor tracking by the fabricator. Moreover, it can be very
difficult to explain complex erection schedules to the steel crew based on 2D drawings.
Additionally, explaining field discrepancies to the project managers and detailers can be
frustrating when the project only uses paper-based documents.
Shop-drawing review and submittals can take weeks and even then there might be several
issues that have not been discovered. Two dimensional drawings allow for a very limited
