Pete Belange, field superintendent at Rieth-Riley Construction, Lafayette, Ind., believes in working smart. In the current economy, he has managed to maintain employees while increasing projects. He credits part of this success to the company’s consistent use of a roller screed. “We don’t have to work harder,” Belange says. “We have to work smarter. Smarter is buying such tools as the Spin Screed.”
Belange purchased his first Spin Screed in 2002 after reading an ad in an industry magazine. The first project he used it on was a mile-long, two-lane highway without a curb, gutter and sidewalks. His crew had to convert it into a four-lane highway installing a 5-foot-wide walkway on one side and a 10-foot-wide path on the other.
“I mainly bought the Spin Screed for the 10-foot-wide path,” Belange says. “It picked up my production over 35 percent the first day, and the guys weren’t as tired at the end of the day.”
Belange found such success using his first roller screed that he purchased a second in 2008. On some projects, Belange uses the roller screed every day — sometimes three or four times a day. He has variable widths of tubes taking about 3 to 4 minutes for one worker to change.
A pervious tool
Recently, Belange used his roller screed on a project for the Water Treatment Plant in West Lafayette, Ind. The parking lot consisted of pervious and impervious concrete. Belange’s crew poured the pervious parking areas in order to drain surface water without putting in a lot of drain piping. Next to the pervious parking areas the crew poured impervious concrete. Most of the work was done using a 22-foot roller screed, but 13-foot roller screeds were used on a few other areas.
The jobsite was located along a river in a hilly area producing severe grade elevations. Because it was such a severe grade, the vibratory screed would have made the concrete crawl down as it moved. Instead, Belange used the roller screed to keep the material where it was placed.
In this situation, pours tend to be smaller and more frequent, but the ease of the roller screed allowed the crew to pour less frequently with larger sized pours, Belange says. This saved the crew tremendously on time. “We were gaining a whole 50 percent every pour,” he explains. “When you do that you’re buying time and making profit.” Rieth-Riley poured about 4,000 square feet per day.
The project was completed in four weeks, two weeks ahead of the projected schedule. As a result, Rieth-Riley was able to come in with a profit margin 10 percent more than projected.
Rieth-Riley rents several pieces of equipment such as backhoes, skid steers and rollers. Each job they finish ahead of schedule allows them to rent that equipment for a shorter time and saves the company money, Belange adds.
“I need to buy time, and I have to create jobs,” Belange says. “We can bid jobs lower and secure more work to keep more people working to utilize the rest of the company.”
According to Belange, another advantage of a roller screed is it places the rock down to the right depth improving the finishing characteristics. “We want to finish the paste, and we don’t want to finish the aggregate.”
