With the restoration work focused near the tarmac, Western crews had to ensure that all worksite debris was contained during the two-month project. Located at 1801 23rd Ave. N, Fargo International Airport is home to four airlines with non-stop service to 10 cities.
“We used our grinder with shroud and vacuum set up to remove the old mortar,” says Minneapolis Branch Manager Mike Tripp. “But when any large debris fell from the brick facade, it had to be collected immediately and covered or disposed of due to the nearby pedestrians, aircraft and life flight helicopter taking off and landing at any given time. So, it was something that we had to be more cognizant of while working on the tarmac side.”
The scope of the project included 100 percent tuckpointing of the masonry structure using a Type “O” historic pointing mortar replacement. Western crews also replaced 50 damaged bricks and six architectural concrete cap stones.
Improving the building’s water mitigation system was also a priority on the project. Western crews installed tubular weeps, or vents, above each window steel lintel to assist with water drainage. The weeps were drilled directly into the mortar and installed every foot for about 500 feet.
To complete the project, Western crews replaced all sealants with 4,000 lineal feet of silicone, then cleaned and sealed the entire building.
The architect on the project was T.L. Stroh Architects of Fargo, N.D.
