HARRISBURG, Pa., April 5, 2013 /PRNewswire-USNewswire/ -- The Pennsylvania Historical and Museum Commission, in partnership with the Pennsylvania Lumber Museum Associates, will hold a groundbreaking ceremony for renovations to the Pennsylvania Lumber Museum Visitor Center at 10 a.m. on Monday, April 22. Representatives of both organizations will join elected officials and community leaders to begin renovations to the existing 8,700 square foot visitor center. Approximately 7,000 square feet will be added to the building. The museum, located in Galeton, Potter County, interprets the colorful heritage of the state's prosperous lumber era when white pine and hemlock were the wealth of the nation. The additional space will provide a new handicapped accessible entrance, expanded exhibit galleries and a state-of-the-art collections storage area. The renovated visitor center will house galleries and exhibits, museum offices, meeting space for community groups, visitor amenities, a library and a gift shop. The new addition, like the original visitor center constructed in 1972, will feature rough-sawn board and batten hemlock siding, which was used at many lumber camps, and stone cladding. The new entrance will be lowered to the parking lot level and include an elevator to the gallery on the main floor above. The project also includes a new fire suppression system and a new roof. A new heating, ventilation, air conditioning and humidification system will be a major component of the project because of the importance of maintaining stable temperature and relative humidity levels for museum collections. Sustainability is a key element in the renovation, with energy efficient lighting, occupancy sensors, natural day lighting, and a geothermal heating and cooling system all incorporated in the design. New restrooms will be provided and the existing sanitary system will be connected to the sewage treatment facility of an adjacent commonwealth property, Denton Hill State Park.
