Thinking Outside the Box Leads to Profitability
Published: 27/9
Many contractors have a strong interest in adding a demolition robot and its capabilities to their fleet — but they aren’t sure how to justify the price tag. Or, in other cases, a contractor invests in a demolition robot for a specific project and then isn’t sure how to maximize the purchase.
The ever-changing landscape of construction and demolition projects makes innovative thinking a must, especially when it comes to adding new equipment to a contractor’s lineup. Contractors shouldn’t just add equipment; they should ask themselves how they can make sure that equipment is profitable. The secret to profitability with demolition robots is thinking outside the box. The versatility of demolition robots gives contractors options, but it can be easy to get stuck in the small box. Savvy contractors make demolition robots an integral part of their business by expanding into new service offerings by utilizing machine versatility, safety features, and equipment integration.
A different approach
Thinking creatively about robotic demolition machine versatility gives contractors the opportunity to reconsider processes on the jobsite. Unlike many specialized, inflexible pieces of equipment meant for demolishing buildings or removing refractory, demolition robots offer surprising versatility that extends far beyond what contractors might expect from the demo-focused name. Many contractors, after purchasing their first demolition robot, find that the machine comes in handy in more places, allowing them to utilize the machine for multiple applications on a jobsite. For example, a Wisconsin-based sawing and demolition contractor found he could expand his concrete cutting options with the help of a demolition robot and concrete crusher attachment. The addition of the machine gave this contractor higher profit margins and allowed for lower bids because his crew could reduce removal time by more than half. His business ended up expanding from one demolition robot purchased in 2007 to 27 robots by 2020. Additional attachments gave the contractor the ability to effectively remove concrete and rebar, making a safer, more productive jobsite.
To make the most profit off the purchase of a demolition robot, it’s important to consider all angles of a project to see where the machine can fit in. Each demolition robot pairs with several attachments, giving operators the opportunity to expand into new applications. The addition of one simple attachment can make other equipment obsolete.
Some manufacturers even team up with demolition robot manufacturers for specialty application attachments. A contractor in St. Louis used a demolition robot with a custom mounting bracket and specialized drive head to install a series of helical piers for a facility retrofit. In that case, one demolition robot replaced a mini excavator or skid steer and provided a zero-emission installation option for working underground. To get into tight spaces without sacrificing power, some demolition robot manufacturers scaled down their machine sizes. Smaller models of remote-controlled demolition robots perform on part with machines three times their size. The biggest difference between a demolition robot and something like an excavator is the power-to-weight ratio. A 5t demolition robot easily handles a 1,600-lb (726kg) breaker designed to fit a 10t to 17t excavator. The compact size opens the door to all kinds of possibilities to do work in limited access, confined spaces or where floor loads are an issue.
Investing in Safety
The biggest safety advantage demolition robots have is that industry-leading models are remote-controlled. In cases where demolition robots take the place of manual labor and large crews, the machine can do four to five times more labor while reducing contractor liability. Robotic demolition machines provide a safe solution for tackling projects in inhospitable environments such as areas with fall risks, excessive heat, fire hazards, fumes and even toxins. Whether the project is inside a building ready to be demolished, underground in tunnels or even in a kiln, demolition robots remove crew members from danger. The radio link system used for transmission works at a range of up to 984 ft (300m), which allows the operator to work from a safe location in every situation. In some cases, the operator doesn’t even need to be in the building while the robot works and can supervise and run the equipment through a video monitor. In another example, a contractor found that the addition of demolition robots cut down on refractory removal and reinstallation times and increased project safety. Relying on the robot’s remote operation, the company virtually eliminated falling debris injuries, which resulted in a reduced experience modification rate (EMR) and lower insurance premiums. The contractor also reduced crew size for descaling and de-bricking by 75% while achieving removal rates up to 33 ft (10 m) per hour. Reallocated crew members were then able to increase productivity on other tasks, leading to a boost in overall efficiency.
An Integrated Approach
The key to introducing a demolition robot to any jobsite is making sure that the equipment is integrated completely into the processes. The robot will tear down more than a traditional crew can during shorter time periods — but the project can only move as quickly as its slowest process. Without the proper support set up, the robot rests while cleanup efforts drag on. Therefore, contractors should consider ways to automate or expedite the rest of the job to get the most out of their demolition machine whether that means mechanizing the cleanup process with a skid steer, compact track loader or mini dumper, or using an excavator or similar equipment for moving material to the load out zone. Mechanization ensures that cleanup efforts keep up with the addition of the demolition robot on site and that projects are kept moving. Owners and operators are finding other new ways demolition robots can expand business opportunities without losing out on profits. While increasing safety and efficiency for crew is important, it’s also important to make sure support equipment and processes are well thought out and on hand to maximize the use of demolition robots. While the machine price tag is a heavy consideration, the benefits outweigh the costs when it comes to remote-controlled demolition machines.
