What’s in a Grade?

One of the most durable and cost-effective choices for scaffold plank by mason contractors is solid sawn scaffold plank. The two main choices these days are MSR (Machine Stress Rated) and DI 65 (Dense Industrial 65), both made from Southern yellow pine species, manufactured mostly in the Southern United States. Before the very first load of “Scaffold Grade” plank was made in 1972, mason contractors and other trades used solid lumber boards of whatever species they could find.

Wood Scaffold Plank Performance

Wood scaffold plank is undoubtedly a critical component within scaffold assemblies, as worker safety depends on the performance of the planks on which they stand. Nowadays, the product offering of wood scaffold plank is quite diverse. Aside from traditional solid sawn lumber planks that are visually graded to meet OSHA standards, there are various types and qualities of manufactured or laminated wood scaffold boards to consider.

The EZ Compact Mast Climber: Unconventional Scaffold for Tight Spaces

“I hate frames!” How many times have you heard that phrase? I hear this one a lot, too: “I’d love to use EZ Scaffold, but this is not a mast climber job. I don’t want to use frames, but I don’t have a choice.” The fact is, we will never completely eliminate the need for frame scaffold. However, the use of mast climbers dramatically increases safety and production while decreasing labor.

Case Study>>>> The Impact of Staining on Masonry

World-famous for its Golden Dome, the 137-year-old Administration Building at the University of Notre Dame (UND) serves as headquarters for its president and provost. The 1879 building is a must-see destination and a popular place for picture taking. Its exterior brick, in particular, demonstrates the ingenuity of builders in the late 1800s. Since the clay was excavated from the two lakes on campus, the finished yellow bricks are known as “Notre Dame bricks.”

Case Study>>> Restoring the Historic Chickasaw Nation Boarding School

Established in 1854 near the banks of the Red River in a small town called Lebanon, Okla., sat an abandoned, two-story brick structure. It once served as a boarding school for Chickasaw Nation girls, an orphanage, then as a manual labor school where Chickasaw children learned agriculture, horticulture, homemaking, sewing, knitting, cooking and housekeeping. Steeped in Chickasaw history, the structure, named the Burney Institute, had fallen into disrepair when it was abandoned some time after 1910.

Moisture Management’s Front Line

Advancements in building technologies have produced both lighter-weight materials that help reduce initial construction costs and the ability to create tighter building envelopes, which can lower lifetime energy costs. As beneficial as these overall savings are, using such technologies poses the potential for moisture damage and associated costs down the road. Fortunately, the right combination of building technologies, products and installation techniques can net the benefits of efficiency and economics while also protecting against moisture damage.

Specifying the Right Waterproofing Coverage

Masonry restoration and preservation are very important to the life of a building. Although building exteriors are made of durable and resilient materials such as brick or stone, they are consistently subject to weather, pollutants, ground movement and moisture. If masonry distress is ignored or not prevented properly, a building’s structural stability could be compromised.
