Heating, ventilating and air- conditioning systems are often invisible to the occupant. Hidden behind walls and snaking through ceilings, HVAC is noticed only when it breaks down.

A U.S. computer data center located next to the Great Lakes is updating a traditional local method for cooling a building to reduce its energy consumption. Due for completion this June, the $150-million facility near Buffalo, N.Y., can turn an entire building into an air handler, powered by fans of the servers they house. “We are applying lessons that were learned during the industrial revolution in Buffalo to a modern data center, which is a new industry in Buffalo,” says Scott Noteboom, director, data-center engineering operations at Yahoo Inc., the Sunnyvale, Calif.-based owner. Like its industrial-revolution forbears, the data center
Traditional evaluation of structural soundness relies on measurements, calculations, observations and assumptions, but now engineers have a new tool that brings a far greater level of precision to the processes. Photo: STRAAM A utility had to cut cladding on a cooling tower and worried how far it safely could go. Analysis showed it danced in the wind but was safe. Formed in 2008, Easton, Md.-based STRAAM LLC—which stands for “structural risk assessment and management”—offers a service that records movement in any kind of structure, from buildings and bridges to cooling towers and wind turbines. Its instruments report the least tilt,
An industry consortium founded 10 years ago in Texas had a straightforward goal: to connect capital facilities owners and builders with the most promising emerging technologies for the improved delivery of their work.FIATECH begins its second decade with a sense that its mission is succeeding.

Plans are moving forward for the first, $750-million, 25-mile section of the long-awaited $4.5-billion Baton Rouge Loop transportation project. Slide Show Photo: put photo credit here photo caption here The overall project includes an 80- to 90-mile controlled access toll roadway that will encircle Louisiana’s capital city metro area and alleviate congestion by providing additional capacity to Interstates 10 and 12 and alternate routes for local traffic. The first 25-mile section “has been broken out into an independent project,” which means it can advance ahead of the rest of the job,” says Bob Schmidt, assistant vice president and BR Loop
One growing pain many construction companies endure comes from a need to shift business and project management processes to a system that integrates data across all processes. Enterprise resource planning (ERP) systems do just that, and there is an upsurge of interest in them. But vendors and companies aren’t consistent when they use the term, and excessive claims are made.

BENEFITS: ERP pays off for Shimmick on a $190-million project, tracking 600,000 hours of time and labor. As an idea, ERP, when used to unify
Building information modeling, still relatively rare in the transportation construction world, proved key in gaining public approval for a planned $573-million, 9.4-mile rapid-transit bus system in Hartford, Conn. Advocates hope transit agencies will begin to ramp up use of BIM in future projects. Slide Show Image: SEA Three-dimensional imaging proved a valuable public-outreach method. The Connecticut Dept. of Transportation had planned on design-build for the line connecting Hartford and New Britain. “We had a designer bring the project from [environmental permitting] to 30% design,” says Michael Sanders, ConnDOT transit administrator. But after then-Gov. John Rowland (R)—who had approved special design-build
California Engineering Contractors, Pleasanton, Calif., was not happy with its high-speed Internet options. Even while paying thousands of dollars a month for bonded T1 lines or similar high-end connectivity at its main office, field offices at projects were often stuck with limited broadband. “In construction, sometimes you just don’t have the facilities for a T1,” deadpans Sam Hanna, CEC Internet technology director. Photo: Mushroom Networks The Truffle can bond up to six internet connections. But most of the company’s data traffic moves between project sites and the main office, and slow connections and digital bottlenecks can cost money. So CEC
Mapping existing broadband service is a requirement for states angling for a piece of the roughly $4.2 billion in matching American Recovery and Reinvestment Act funds for high-speed Internet expansion. But with a deadline approaching, states and municipalities have been scrambling to find the data. Photo: Connected Nation Michael Ramage (left) explains BroadbandStat at its debut at a Congressional policy exhibition in Washington, D.C., where it attracted interest from local officials seeking to expand broadband. Now, a new tool is available to help. In February, Connected Nation, a Washington, D.C.-based nonprofit dedicated to expanding high-speed Internet access, launched BroadbandStat, a
The Haitian government has estimated it will take 10 years and $3 billion to repair the damage caused by Jan. 12’s magnitude-7 earthquake, although some warn it may cost more than three times that amount.
