Bad drivers can put their employers at risk. Whether an employee is driving a company car or being reimbursed for driving their own vehicle on company business, the employer can be accused of negligent entrustment following a collision. In simple terms, negligent entrustment means an employee or contractor was dispatched to drive without proper regard for his or her qualifications and/or ability to safely operate a vehicle. Because settlements can be large and judgments can include punitive damages for egregious behavior, employers need to take note. Although the driver’s own negligence in causing a collision may be the primary issue,
在一个行业已经在危机jobsi上升te deaths and injuries and now in a rush to start and complete economic stimulus projects worth many billions of dollars—where, ultimately, does responsibility for worker safety lie? Does it, as some argue, rest partly with individual workers, or should employers, project owners or even the government be held fully accountable when there is an accident on a construction site? READ AND COMMENT ONTHE DUELING VIEWPOINTS: Proposal: Accident Prevention Is Everyone's Responsibility Reply: Unrealistic Plan Poses Many Problems And Won't Do the Job Earlier this year, ENR published a Viewpoint titled, “We Need
A small precast-concrete bridge in New Jersey is being replaced with a hybrid-composite beam structure that could have a service life of 100 years. This is the third project using the technology, which combines a glass-fiber reinforced shell, self-consolidating concrete for compression reinforcement and high-strength continuous steel fibers for tension reinforcement.

LLC, Chicago, is supplying beams for the $1.34-million state Rte. 23 Peckman’s Brook Bridge in Cedar Grove, N.J. The 50-year-old four- lane, 66-ft-wide, 30-ft-long bridge is considered structurally deficient and is
To safeguard downstream residents, work now is under way in California to seismically upgrade the San Pablo Dam. The $54-million project involves removing an existing buttress, strengthening the downstream foundation using cement deep-soil mixing and constructing a new 85-ft-high by 950-ft-long buttress. The San Pablo Dam, located near El Sobrante, is an 89-year-old, 38,600 acre-ft drinking-water impoundment. It is managed by the East Bay Municipal Utility District (EBMUD), which serves 1.3 million people in parts of Alameda and Contra Costa counties.

The Massachusetts Water Resources Authority on June 25 awarded a $4.9-million contract to the Boston office of Stantec for engineering services on the 45-year old, 60-mgd West Roxbury Wastewater Tunnel. The 12-in thick cast-in-place concrete lining in the 12,500-ft long, 84-in dia. rock tunnel, which serves about 125,000 homes and businesses, is eroded due to hydrogen sulfide corrosion. J.F. White, Framingham, Mass., will inspect the tunnel, which has two portals and a 220-ft deep shaft, this fall to help determine the extent of the problem and the relining solution. "The 12-in liner is structural and as of a decade ago
Three years after the state of Connecticut failed to generate any bids on the nation’s first extradosed bridge project—a hybrid cable-stayed, box-girder structure—three firms now are competing for the superstructure work. The low bid is about $33 million below engineers’ estimate. Photo: URS Corp. Reduced bid package helped generate three bidders for Q bridge superstructure work. When bids were opened on June 3 for the Pearl Harbor Memorial Bridge, known as the Q bridge because it spans the Quinnipiac River, the joint venture of Walsh Construction Co., Sharon, Mass., and PCL Civil Constructors, Tampa, Fla., was the apparent low bidder
The green revolution may be a much-ballyhooed fixture with architectural, engineering and construction cognoscenti, but what happens when the revolution actually arrives on the doorstep of the traditional blue collar, Irish Catholic, family-oriented stronghold of South Boston? Wicked Delicate Films' production of The Greening of Southie successfully explores that theme with a hip blend of time-lapse photography, great music and on-point dialogue as a young management team leads skeptical tradesmen through the experience of assembling an 11-story, 144 unit condominium project called the Macallen Building.

Thirty-two years after the last polychlorinated biphenyls (PCBs) were discharged into the Hudson River from manufacturing complexes, General Electric Co. began dredging on May 15 to remove 400,000 tons of contaminated sediment along a six-mile stretch near Fort Edward, N.Y. Additional dredging is planned downriver along a 34-mile section to Troy for a 2015 completion. + Image Source: General Electric Co.

最近的一项研究由联新利18备用邦交通Administration concludes that the nation’s largest transit agencies need at least $50 billion to bring their assets into a state of good repair and another $6 billion would be needed annually for normal maintenance. The Rail Modernization Study, completed in April at the request of Sen. Richard Durbin (D-Ill.) and 11 other senators, examined capital needs of the seven biggest U.S. rail transit agencies. It looked at older systems in New York, Boston, Chicago and Philadelphia, as well as newer systems in San Francisco, New Jersey and Washington, D.C. Combined, the agencies serve
Foundation work for a signature bridge is under way as part of a $2.2-billion Interstate corridor project in Connecticut. Critical elements include constructing the nation’s first extradosed bridge and beefing up commuter rail service in what Connecticut Dept. of Transportation officials say is the largest single construction effort ever undertaken by the agency.
