"BIM Consensus Standard Is a Step Forward but Not a Major Leap Toward Interoperability" should have stated that Nemetschek Vectorworks and Graphisoft are owned by the same company, Nemetschek Group. Also, the headquarters of FM:Systems is located in Raleigh, N.C."Cracks Slow Pontoon Job" erroneously stated Kiewit-General is widening state Route 520 east of the floating bridge. Eastside Corridor Constructors, a joint venture of Granite and PCL, is on that job. Alleged on-the-job drinking did not involve anyone from ECC.
The cover story "Boardrooms Raise the Bar" was interesting and made good sense, but it missed the main points for [director] qualifications today: truthfulness, honesty, ethical behavior and moral integrity.Harry Watkins, P.E., Retired President Watkins Engineering Consultants Inc.Birmingham, Ala.
The membership of Allied Building Metal Industries Inc. were dismayed at the contents of your recent editorial "Making a City Safe for Cranes," in which you suggest that users should de-rate a crane's load chart so every lift in New York City defaults to a critical lift.Crawler cranes already have a standard 75% reduced chart; truck cranes are at 85%. A further reduction to 75% would limit the crawler capacity to 56%. There is already a built-in factor of safety in the manufacturer's approved charts. Cranes are typically load-tested to at least 130% of rated capacity. A further reduction to

In response to your article, "Special Report: Which Way the Winds Are Blowing on P3s", the American Subcontractors Association would like to raise your awareness about a concern that construction subcontractors and suppliers have with public-private partnerships (P3s).Specifically, ASA is concerned that existing federal and state laws establishing payment assurances for subcontractors and suppliers may not apply to projects financed through P3s.State mechanic's lien laws generally do not apply to construction on public land; yet federal, state or local governments often own the real estate on which projects financed through P3s are built. Statutory payment bonds may be required on

Nor should it be. If congressmen were to dig into life-cycle cost analysis (LCCA) as presented by Massachusetts Institute of Technology's Concrete Sustainability Hub (CSH), funded by PCA, they would find the idea of asphalt pavement costing double that of concrete pavement ludicrous.Notice that the CSH has used theoretic estimations
I read with interest your story "Tutor Perini OKs CEO's Stock Sale."
