Researchers use U. of Arkansas buildings as testbed for CLT panels

A new residence hall on the University of Arkansas campus will serve as a testbed for researchers to study Cross-Laminated Timber (CLT) panels.

Professors in the university’s Fay Jones School of Architecture and Design and the College of Engineering are collaborating to measure and analyze the moisture content of the panels used in the buildings. Adohi Hall is the nation’s first large-scale mass timber residence hall project, according to a university news release.

Construction on the residential areas of Adohi Hall was completed this summer. The hall consists of two five-story residential buildings connected by a third building that provides a common area. To monitor the effects of rain and humidity, sensors were placed in CLT panels in moisture-prone areas—bathrooms, kitchen and laundry areas, and near the exterior of the buildings.

The approximately 200,000 sf project with 708 beds was designed by Leers Weinzapfel Associates of Boston, Modus Studio of Fayetteville, Mackey Mitchell Architects of St. Louis and OLIN of Philadelphia. CLT panels were used in floors and ceilings. Columns and beams were made from glue-laminated pieces, which are bonded together with the wood grain of each layer running parallel rather than perpendicular, as CLT panels do.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
