Making such a complex process user-friendly is a challenge.BridgePBEE, a graphical pre- and post-processor performance-based earthquake engineering (PBEE) analysis tool, aspires to do just that. The beta version is available for free download from the University of California, Berkeley's Pacific Earthquake Engineering Research (PEER) Center.The PC-based tool lets engineers conduct PBEE analysis
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.
