Water Pipeline Contractor Embraces Vacuum Lifting

A US-based construction company hired to build approximately five miles of coated steel pipeline wrapped up a yearlong water distribution line project ahead of schedule and under budget with the assistance of vacuum lifting technology.

Kissick Construction Co. was retained by the independent public utility WaterOne, on behalf of Water District No. 1 of Johnson County, to install a 48” diameter pipeline as part of the Hedge Lane pump station, reservoir and pipeline project in rural Kansas. The company began work in September, as crews conducted surveys and started clearing trees west of and running parallel to Interstate 35. By November, pipe-laying teams commenced activities in the lane.

Kissick used Komatsu PC600 hydraulic excavators to dig as a Vacuworx RC 16 Vacuum Lifting System, attached to a Komatsu PC400, unloaded the 10 to 12 trucks that arrived daily over the course of 12 months to various staging points on the route. Altogether, Kissick accepted delivery of more than 24,000 linear feet of pipe, which was typically laid out in 50-foot sections along the right-of-way.

New Heights

Prior to its experience with vacuum lifting, Kissick had been employing the use of nylon slings, which required up to three additional workers, to hoist heavy duty pipe and lower it into a trench. The Midwest-based contractor first rented the Vacuworx system, but within three months made the decision to purchase the RC 16 as crews realized greater efficiencies, compared with conventional pipe handling methods. “The way they stack pipes on the truck, it is about 10 feet to 12 feet off the ground,” said Kissick Project Superintendent Chris Oxford. “I just didn’t really like laborers going up there and crawling around, especially with frost or in inclement weather. Without Vacuworx, I would be using four people to maneuver one pipe weighing in at around 12,000 lb. It usually took two guys just to get the slings on. Now there is no need for anyone to be up there anymore.”

Rough Terrain

Kissick is no stranger to taking on rural terrain as demonstrated by a project portfolio including earthwork, utilities, bridges and structural concrete, among other heavy-duty applications in critical construction environments. With regard to Hedge Lane, uneven ground proved challenging as Kissick was required to cross numerous roads, creeks and railroad lines while overcoming each of these obstacles on its path to timely completion. Oxford said vacuum lifting saved time and allowed crews to run more effectively, in spite of some unforgiving landscapes.

“This was a demanding job in that there was a lot of ups and downs, around the corner applications,” Oxford said. “It saves a lot of time not having to rig up the pipe, especially when you have two excavators running on the site. We got a rhythm going on those long, straight runs. Then it was like a lightening bolt went off. The Vacuworx machine gives our operator complete control, making it easier to lay and connect pipes in the ditch. In other situations, it was worth having just for the unloading part.”

The Hedge Lane project also presented a new opportunity for Kissick, which has years of material-handling experience with PVC or Reinforced Concrete Pipe, to work with a coated steel product that requires the performance of a Holiday test, as a method of detecting scratches, pinholes, voids or undesirable discontinuities.“

There is a special, time-consuming protocol to patch or repair this type of protective tape coating,” Oxford said. “In hotter weather, the slings have a tendency to cut into the tape wrap and damage it. Any movement of the tape or appearance of an air pocket would mean having to redo it. The Vacuworx system reduced the potential for any damage. We simply picked up each piece, ran our continuity test, patched if necessary, and repositioned the pipe in the trench – all while maintaining a high level of safety and productivity. It just sped up the whole process, compared with the old, traditional ways.”

Coming Together

Kissick Project Manager Matt Rothermel said the company strives to foster innovation by pairing new technology with the expertise of team members. The contractor values these types of collaborations, he said, as they relate to proven engineering practices and the core of its heavy civil construction services.

Given it was the first time Kissick had worked with this specific type of coated pipeline, Rothermel said there was more than one school of thought in terms of how to handle it in the field. “Our guys are always on the lookout for new ways to help us improve on our estimates, whether it’s matching new software with an application or coming up with a simple tool for use the field,” he said. “It has a lot to do with quality and a lot to do with safety. They ultimately hone in on and tweak what works best. Now they can do it faster, too.”

One aspect of Kissick’s decision to purchase a vacuum lifting system revolved around the versatility associated with the Vacuworx brand. “The first time we laid eyes on it was in Tulsa,” Rothermel said. “We don’t like buying toys, per se. For us, it’s more about making an investment and capitalizing on the return of providing good service to our clients. This isn’t just for one kind of pipe or a specific piece of carrier equipment. We can take the machine and outfit it with different pad systems. That sets us up for a wide variety of applications.”

“Our customizable pad systems are manufactured to be highly effective with delicate materials or coatings, and are available with quick-coupler systems for superior adaptability,” said Vacuworx National Sales Director Randy Hayes. “Our customers appreciate these advantages and overall usefulness of vacuum lifting technology. It presents a faster, smarter and safer material-handling solution – in an array of rigorous working environments and weather conditions. We worked closely with Kissick and developed a system that is intended to meet both their short- and longer-term needs.”

“It was pretty simple on my end,” Oxford said. “When I don’t have to have those three guys on the ground unloading pipe, that saves money. “It relates back to how much you can cut down on manpower or boost productivity in other areas. If somebody sat down and put ink to paper, it wouldn’t take long to see how a machine like this pays for itself.”
