Structural Engineer / Team Coordinator
The McCallum crew is absolutely the best and I wouldn’t hire anyone else for blasting and drilling. The team is highly professional and experienced and I can trust them every time to do a “bang-up” job! One of the things I like most about their crew, aside from their efficiency, is how nice and clean everything is after they’re done. They always leave the place spotless. Highly recommended.
I’d like to say thanks to Tyler and the McCallum Rock Drilling team for their expert handling of the Lake Cushman dam project. They had the challenge of highly technical close-in blasting next to the dam and had to ensure each blast was designed to maintain safe ground vibration limits at the dam. Multiple seismographs were used to monitor ground vibration and hydrophones were used to monitor water overpressure. McCallum Rock Drilling used state of the art electronic detonators and drilling techniques to safely ensure the success of our project.
I’d like to thank you and your crew for the safe and efficient job you did when we hired your team as a subcontractor to replace the 87-year old Sellwood Bridge in Portland, Oregon with a new seismically-sound structure (the busiest two-lane bridge in the state of Oregon). I’ve worked with just about every drilling and blasting company in the Northwest and I would put McCallum Rock Drilling at the top of the list for safety, expertise and efficiency. The blasting job they did to widen the roadway for the new OR 43/Sellwood Bridge intersection couldn’t have gone better. Absolutely outstanding work and I’d recommend them first.
