Kuidas muudab mudelprojekteerimine teraskonstruktsioonide valmistamist ja ehitamist
With this method, steel
erection can begin immediately following the release of construction documents.
Matt Trammell, the structural engineering manager at TRC Worldwide Engineering
Inc., based in Brentwood, Tennessee, has estimated that at least two months of
construction time was eliminated in a recent hospital project due to the

• Cost – An article by C.J. Carter and T.J. Schlafly titled “$ave More Money” (2008)
lists three items that make up a cost estimate of a steel structure:
o Material costs 25%
o Fabrication and erection labor costs 60%
o Other costs 15%
Therefore, in today’s market, labor in the form of fabrication and erection
operations typically accounts for approximately 60% of the total constructed cost. In
contrast, material costs only account for approximately one quarter of the total
