Precision Demolitoin
The Brokk 90 is one of the most versatile and safe demolition tools on the market. It is the obvious choice for indoor demolition where there are load restrictions on floors, but where a powerful and labor-saving tool is needed. The Brokk 90 folds into a compact package, fits into most any elevator and even climbs stairs. It can be plugged in and ready to work in an instant. Front and rear fold down outriggers provide exceptional stability in uneven situations. While its remote control feature ensures complete safety for the operator in hazardous environments. In addition, beyond its low operating noise, the Brokk 90 does not create harmful vibrations when using its crushing attachment to disassemble concrete. And because it is electricly powered it is exhaust emission free.
Slab and Curb Sawing, Bridge
Client
Slagter Construction
Project
The Michigan Department of Transportation’s (MDOT) contracted with Slagter Construction—who’s been in the highway construction business since 1955—to rehabilitate a bridge over the Grand River in Grand Rapids, Michigan. Part of the work required the replacement of the bridge barrier rail and concrete deck, as well as repairing portions of the bridge’s steel structure. In addition, the Michigan Department of Environmental Quality (DEQ) specified that no debris could fall into the river during the cutting of the concrete bridge barrier. Similarly, the slurry generated while sawing the barrier had to be contained so it would not drain into the river.
Process
Diamond used a custom-built ride-on horizontal curb saw to cut the 12 inch-thick barrier on both sides of the 500 foot-long bridge. Diamond’s ride-on horizontal curb saw, capable of cutting barrier walls as thick as 24 inches, cut the barrier wall flush to the remaining pedestrian walkway. Finally, to downsize the concrete pieces for easier removal, Diamond used high-horsepower slab saws to make vertical separating cuts in the barrier rail. In addition, Diamond provided Slagter with equipment to collect and properly dispose of the generated slurry.
Outcomes
Diamond was able to complete the work within 2 days, on time and on budget. According to Mark Price, Project Manager for Slagter. Diamond met Slagter’s expectations for timing and quality of work. “The horizontal cuts they made were flush to the remaining sidewalk and in some situations that is not always easy to do,” said Mark. “I was pleased with their work and will definitely contact them again when future opportunities arise where their expertise and equipment may be of use.”
