Poor quality, often homemade concrete led to widespread building damage in Port-au-Prince following last month’s earthquake in Haiti, says Ken Hover, an engineering professor at Cornell University who had recently returned from the devastated city. Slide Show Photo: Ken Hover Some buildings suffered cracks rather than total failure from Haiti's devastating 7.0 magnitude earthquake on Jan. 12. Hover made his remarks Feb. 3 at the World of Concrete tradeshow in Las Vegas. He had performed structural assessments for two university-backed Port-au-Prince health clinics from Jan. 20-25. The clinics consisted of 15 separate structures. Hover says he used California's post-earthquake investigation
In an unusual move in the highly commercialized sports market, the city council of Irving, Texas, voted on Dec. 31 to award naming rights to the demolition of Texas Stadium to Kraft Foods Global.

一种s stormwater runoff from streets and parking lots becomes an ever-more sensitive environmental issue, eliminating it altogether with pervious pavement can be an elegant solution. Two projects now under way in Connecticut and Minnesota have facilities owners, municipal officials and the paving sector taking notice. One involves a parking lot at a university committed to cutting its impervious surfaces by half. The other is a public road in Minnesota, where a city engineer insists he is not experimenting; he is just applying a best-fit solution to a 50-year-old problem. Both applications share one thing in common: they are engineered to
