The American Society of Civil Engineers has decided that emergency changes to wind-load provisions in ASCE's 2010 building design standard are not needed. ASCE recently reviewed the provisions, prompted by a red flag raised by structural engineer-researcher Emil Simiu, who says the wind standard is flawed and needlessly complex. SIMIUInconsistencies in chapters 26-31 of the 608-page “Minimum Design Loads for Buildings and Other Structures: ASCE/SEI 7-10” can result in “unconservative” designs, says Simiu, a member of the 2010 standard's subcommittee on wind loads. “Some buildings can be produced that do not meet the intended risk levels implicit in the standard,”
The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
