| Historic Ohio barn gets replica slate roof |
| Back in 1883, a timber-framed, standard Pennsylvania-style barn was constructed with a real slate roof on the homestead of the Hartong family in Green, Ohio. After more than a century of service, the worn out slate roof—and the rotting wood structural support system beneath it—have finally received a facelift. A single-width composite slate roof was employed because of its lightweight composition, affordability, and durability. The specified tiles enabled the project team to retain the historic character of the barn, even to the point of recreating the large “1883” date on the roof. |

| Dual-technology exit signs eliminate battery backup |
|
| For building owners and managers striving to meet fire and safety codes, “dual-technology” exit signs that combine the efficiency of light-emitting diode (LED) lighting with new photoluminescent (PL) materials can help increase reliability and performance over decades of use. This hybrid approach combines two established exit sign technologies in a single unit. During normal power conditions, the sign is illuminated with highly efficient LEDs. When the power goes out, a translucent exit stencil diffusor made of PL material provides the illumination. This is charged by the LEDs while electric power is provided to the sign. Read on to learn more about these new-age signs. |

| Transforming Chicago’s riverfront |
| Built on a desirable, but long-vacant parcel of land in downtown Chicago, 150 North Riverside has been hailed as one of the most spectacular engineering feats in the Windy City’s history. Rising from a site constrained by seven active railroads, two bordering and elevated roadways, and the Chicago River, the project team turned the prohibitive site into a gleaming look-into-the-future-possibility of urban construction. This article examines the many design, engineering, and construction components of this now-iconic building, which has changed Chicago’s landscape. |

| Retrofitting buildings with vapor barriers |
| As a result of past activities, some areas (e.g. erstwhile sites of dry cleaners or filling stations) are more prone to the risk of vapor intrusion for its surrounding structures. Vapor intrusion occurs when there is a migration of chemicals containing vapor from a subsurface source such as soil, groundwater, or soil vapor into an overlying building. This may adversely affect a building’s indoor air quality (IAQ), leading to potential health problems for building occupants. More architects are specifying chemical vapor barriers when designing a new structure in locations where vapor intrusion may be a concern. Find out how one can incorporate vapor barriers in a project. |
