Sustainable features of the Vancouver convention center expansion go beyond daylighting controls, some natural ventilation, the 2.4-hectare green roof with 400,000 plants and grasses and restoration of 200 ft of shoreline and 1,500 ft of marine habitat. There also is a “blackwater” wastewater treatment and reuse system, for plant irrigation and toilets, connected to a roof-top stormwater management and reuse system.

The foundation engineer calls the $8.2-million artificial reef—the marine habitat apron—the most unusual element of the Vancouver convention center expansion project. “I know of nothing else like it, anywhere,” says Ryan MacPherson, project engineer for WorleyParsons Westmar Consulting Engineers, North Vancouver. “It’s very successful.” Marine life is already growing.

Canada’s $730-million Vancouver convention center expansion on the city’s waterfront sits on the best of sites. To the north are breathtaking views of Coal Harbor, Burrard Inlet and the North Shore Mountains. Across the street to the south is the city center. Directly to the west is the landmark Stanley Park.

It is not surprising that architects in the earthquake-prone San Francisco Bay Area incorporate robust and sophisticated seismic technologies into their buildings. Some of the earthquake-resisting strategies in the region’s high-profile new-construction projects, such as the coupled shear-wall system inside the twisting and turning tower at the de Young Museum or the base isolators below the just-completed Oakland Cathedral, naturally attract attention because of their unusual design. But older, more conventional structures are continuously being subjected to seismic retrofit and they require at least just as much engineering finesse. Slide Show A seismic retrofit is part of plans to transform
A planned rail transit spur in northern Virginia has moved another step forward, with U.S. Transportation Secretary Mary E. Peters' approval of a $900-million, multi-year federal funding commitment towards the project's $2.6-billion first phase. With Peters' Jan. 7 action, the proposed "full funding grant agreement" goes to Congress for a 60-day review.

Ten-mile hikes, wasp nests and forest fires marked an almost unfeasible feasibility study for a potential world-record road tunnel. Engineering geologists with Kleinfelder Inc., San Diego, are now working on a report, due by fall, for the Orange County Transportation Authority and Riverside County Transportation Commission. It will assess the possibility of building a pair of 50-ft-dia tunnels almost 12 miles long under the Cleveland National Forest in Southern California.

The Texas Dept. of Transportation announced on Jan. 6 that it pulled the plug on the estimated $200-billion Trans-Texas Corridor, a vision introduced by TxDOT and Texas Gov. Rick Perry (R) in 2002. TxDOT Executive Director Amadeo Saenz Jr. made the announcement during the fourth annual Texas Transportation Forum in Austin. Projects already started under the heading of the Trans-Texas-Corridor will continue as a series of individual projects. Portions of two TTC projects are under development: Interstate 69 from Texarkana/Shreveport to the Mexico border and the I-35 corridor from north of Dallas/Fort Worth to Mexico. Perry cited financing as a
The Shaw Group Inc. and Westinghouse Electric Co. LLC have signed a contract for engineering, procurement and construction of a two-unit nuclear powerplant at a greenfield site in Levy County, Fla. Progress Energy Florida Inc., the owner, expects to receive a combined construction and operating license from the Nuclear Regulatory Commission by early 2012. Current plans are for operation of the plant in the 2016-18 time frame, after which Progress Energy will retire its two oldest coal-fired units at the Crystal River Energy Complex in Citrus County, Fla. The new units will be AP1000 pressurized-water reactors, rated at 1,105 MW.
A public-private partnership in the San Francisco Bay Area plans to build a $1-billion network of electric-car charging stations, while in Portland, Ore., a utility and two private firms already are erecting electric vehicle battery-charging stations in a cluster of nearby cities.

Ted Kulongoski (D) to supply electric vehicles to the state’s fleet in 2010. Nissan also committed to work with the state, in partnership with utility Portland General
Dropping demand for gasoline has taken a chunk out of last year’s super-high prices, and refiners are shifting capital expenditures accordingly. Prices for gasoline rose 7.1¢ on Jan. 5 to $1.68 per gallon but were still down 46% overall since a year ago, reports the federal Energy Information Administration. On-highway diesel prices fell 3.6¢, to $2.29, a 32% drop since 2008 and the lowest in years. Despite the winter price rollback for both fuels, diesel is “the growth fuel, globally,” says Allen Schaeffer, executive director of Washington, D.C.-based Diesel Technology Forum. As such, ExxonMobil Corp. and others are boosting output
