Henry J. Knott Masonry Inc., a third-generation masonry contractor, has been in business since 1936, when it was founded by the grandfather of current president Henry Knott III.
Knott Masonry is known for producing award-winning projects throughout the Baltimore and Washington D.C. area. Some of its awarded projects are: Loyola College - Center East Student Center; State of Maryland - Annapolis Data Center; Johns Hopkins University - Decker Quad, and Mason and Hackerman Halls; and the Holy Cross Hospital in Germantown, Md.
Wren Works used a Manitowoc 11000-1 crawler crane to help build a retaining wall at the Mont du Lac Resort, a skiing destination in Superior, Wis. Rigged with 140 ft. of boom, the 110-USt crane lifted an 18.5-USt pile hammer to heights of 75 ft. to drive 14 H-piles. Gangs of timber that weighed 0.5 USt were then lifted to a height of 60 ft. and inserted between the piles to create a foundation for the retaining wall that will eventually shore up the resort’s new banquet room.
