The construction contractor faces tough decisions regarding which markets to pursue and when the best time is to invest in big pieces of equipment. When handled properly, investing in heavy equipment can open doors of opportunity. Yet each machine requires fuel, maintenance, insurance and a capable operator. The purchase decision is important.
For the grading and excavation site prep contractor, there is another big decision to make these days. It is more than a yes-or-no purchase decision. True, it is a financial purchasing choice. But it also is a business decision that pivots the contractor in a new direction, or more specifically, a new operational approach to conducting business. It also is a decision that earthmoving contractors are learning is becoming inevitable. And at the risk of being dramatic, the choice may be as significant as world changers of the past – horse-drawn carriage versus automobile and typewriters versus computers.
The big decision facing earthmoving contractors today is whether or not to embrace GPS machine control technologies. For many the decision is not whether or not to adopt the technology, but when and how quickly. For these early adopters, GPS machine control technology is considered inevitable.
Hoban Equipment Ltd., based in Salmon Arm, recently went through the decision process and metaphorically went from a stroll in the park to a sprint by investing in 13 Trimble® GCS900 Grade Control Systems at once.
A mid-sized construction company with about 200-250 employees and an equipment fleet of more than 200 machines, Hoban Equipment raises questions with its significant investment:
- What prompted the purchase decision?
- How did it come about?
- What research was done?
- How will the technology help?
“Our success is due to people and technology,” states Will Hoban, owner of Hoban Equipment. “We’ve learned that good equipment and newer technology helps bring the better operators to the company and helps us be profitable.”
|The Grade Control System is easily mounted onto the machinery, and interferes very little with the operator’s sightlines.
In a sense, the recent, large investment in technology fits into Hoban Equipment’s commitment to significant business growth.
“We spent two years reading reports, studies and trade magazine articles, as well as visiting suppliers at ConExpo and locally,” Hoban says. “We also had a big project in Regina for a significant customer, CP Rail, and the tolerances on the project were the tightest we’ve ever seen – plus or minus one centimetre on clay sub grade. By this time, I had done a little bit more research on the systems and which ones to try out, so we contacted our local Trimble dealer and they were awesome. They came out, they set the system up, and had us running within three days on the grader.”
The Trimble dealer also took the site plan and created the digital 3D model, which had all the correct data for the machine control for Hoban Equipment’s motor grader.
“We were achieving incredible accuracy, which made me pretty happy,” states Hoban. “The grade was dead on, plus we saw a huge increase in time savings, especially when we were grading the clay sub grade.”
Hoban continues, “I stepped up my research on GPS machine control and the benefits and how it could help a company and I read lots of reports, I bought some of the efficiency studies that had been published, and read all the application story articles posted on the Trimble Productivity website. They all showed significant time and cost savings for construction projects.“
Additionally, Hoban had been following a competitor that had invested in machine control technology in 2007. He observed that in competitive bids for new work, the contractor’s bids were quite a bit cheaper than those of the competition. Hoban concluded its GPS machine control was making a difference.
“In the midst of my research, I was realizing that fuel savings and labour savings alone could offer a pretty quick return on investment over a two- or three-year period,” Hoban says. “In our experience with the Trimble systems, my initial conclusions are holding true.”
|Thanks to the Grade Control Systems, Hoban is able to meet and exceed the tight tolerances demanded by the transport ministry and CP Rail.
“We’ve had the Trimble systems for less than a year now and we’re currently prepping subgrade on a project and we’re within three millimetres of design using a big dozer in clay coil,” states Hoban. “The Ministry of Transportation in British Columbia is just ecstatic.”
The project is Highway 97, Old Caribou Highway, part of the Caribou Connector Project in British Columbia.
Hoban continues, “Historically, what we’ve had to do is build it higher, about a deck higher, and then bring in a grader to finish clay sub grade to get it accurate and we’re never that accurate. We’re lucky to get plus or minus two to three centimetres, and with the dual-mast, GPS-based Trimble GCS900 system, we’re plus/minus half a centimetre on our target. This is also using a brand new machine, a really tight machine, but without the system, we couldn’t do it. We’re completely stakeless on the whole project as well.”
The $9-million portion of the $17-million Caribou Connector Project that Hoban Equipment is working on is a four-kilometre stretch involving about 225,000 cubic metres of excavation on the project and 100,000 cubic metres of granular materials.
“Having machine control on our equipment has definitely helped us speed up our production,” Hoban says. “It depends on what stage we’re at with a project, but in many cases we’re looking at literally a 50 per cent increase in productivity when we have a good operator in the machine who appreciates the technology.”
Hoban remembers an experienced 70-year-old dozer operator on his staff who initially resisted running a machine with GPS machine control.
|According to Hoban, the company has found up to a 50% increase in productivity with operators who have embraced the new technology.
According to Hoban, his 70-year-old dozer operator saw the results and how easy it was for his friend to learn.
“He learned how to run the dozer with machine control and loves it,” Hoban states. “When he gets home at night he’s not stressed out or tired or drained mentally because the machine is doing a lot of the work for him. He said something about waiting another 30 years before retiring. If he continues doing as great a job as he’s doing, we’ll gladly keep him until he turns 100.”
For Hoban Equipment Ltd., investing in the 13 GPS machine control systems at once represents an evolution; a whole shift in attitude and work methodology.
“My goal is to equip all my machines with GPS machine control technology and add connected site capabilities, so we can get accurate field reporting data,” states Hoban. “We’ve always been a company that is attracted to jobs that most contractors find too challenging and the technology helps us meet the challenges, such as working in clay.”
The geology of British Columbia is predominantly rock. Contractors in the province have geared their construction equipment to work in rock. With machine control technology, Hoban says that they now feel confident to bid on either rocky or clay terrain projects.
“The technology has helped us become more competitive and has probably been one of the biggest edges we’ve had in securing more work in clay materials,” says Hoban. “So, we’re definitely pushing outside the box compared to some of the other people that are running the same types of equipment on the same projects.
We’re doing our work differently, which has lowered our cost.”
