Linea Plus is an in-wall radiator unit that features Low-H2O technology, which allows the unit to heat quickly with relatively low energy consumption. It is well suited for use in low-temperature hydronic systems and with renewable-energy sources, such as solar or geothermal. The Linea Plus' design allows for any kind of pipe or vent to be hidden behind the front panel. It has a maximum surface temperature of 109° F, even when the water temperature is 194° F. It is available as a freestanding or wall unit in 25 different colors. Jaga North America; www.jaga-usa.com Featuring an integrated LED driver,
Courtesy Autodesk CEO Carl Bass discusses the new cloud-based features for Autodesk software to industry press at a company media event in San Francisco on March 27.

The Manitowoc 16000 Crawler Crane now is available with a fixed-jib option as well as the standard luffing jib. The fixed jib has a 93-metric-ton (102-ton) capacity and a maximum length of 42.7 m (140 ft). The new jib reduces rigging time for lift applications in which a luffing jib is not required or feasible. Manitowoc Cranes; 920-684-6621; www.manitowoc.com The Atlas Copco Boomer E1 C-DH drill rig features a drilling coverage area of up to 95 sq meters, or 1,023 sq ft. This reach is a significant improvement over the company's earlier diesel-hydraulic face-drilling rig, the L1 C-DH. The rig
The York YVWA Water-Cooled Screw Chiller features a variable-speed drive that allows for more efficient energy usage. It uses HFC-124A refrigerant, which has zero ozone depletion potential and no phase-out date. The screw chiller is able to handle a higher pressure lift than a centrifugal chiller, allowing it to be used in both thermal storage and heat-pump applications. Johnson Controls; 800-537-9675; www.johnsoncontrols.com The Liebherr 65 K Fast-Erecting Crane has a lifting capacity of 1.4 metric tons at 40 meters, with a maximum lifting capacity of 4.5 metric tons. Loads are moved using a pure two-fall operation with no re-reeving. The

A simple request from the University of Wisconsin-Madison for the construction of its 102,000-sq-ft, $27.5-million La Bahn Arena presented an engineering challenge for the contractor."They wanted as much open space as they could get in the men's and women's hockey locker rooms," says Dave Beck-Engel, executive vice president, J.H. Findorff & Son, the project's principal contractor. "But with a traditional concrete slab, it got pretty thick, [and the] low ceilings got in the way."After considering its options, the project team chose to use BubbleDeck, a nontraditional concrete slab system which uses evenly spaced plastic bubbles to reduce the amount of
