Versatile Komatsu equipment, KOMTRAX, and dealer support
In late August 2010, the New York Giants and New York Jets will play a preseason football game against each other in what’s now being called the New Meadowlands Stadium. It will be the first game at the new stadium that houses both National Football League (NFL) teams.
Construction of the new stadium, which sits just 27 m (30 yd) from the old Giants Stadium that was home to the teams for 35 years, is near completion. So is the demolition of the old stadium, which Westbury, New York-based Gramercy Group, Inc. began on February 4, 2010 with abatement work and demolition of the Gate B walkway helix closest to the new stadium. Physical demolition started on March 20 when the company took its first bite out of the concrete shell of the 75,000-seat stadium.
Because the old stadium and the new are in such close proximity, implosion was not an option as part of the demolition process. That means Gramercy has to take down the structure with near surgical precision to ensure safety for the more than 100 employees who work at the site.
Effective Utilization by Recycling Materials
Gramercy expects to finish the more than $10 million project in late July 2010, leaving an area for a future parking lot for the new stadium where the old stadium once stood. Underneath that parking area will be an enormous amount of concrete that Gramercy recycles on site as part of the demolition process.
“There will be a hole where the field was, and that has to be backfilled with about 160,550 m3 (210,000 yd3) of material,” Mr. Vincent Parziale, president and CEO of Gramercy, pointed out. “Some of that material comes from excavation of the new stadium. As that took place, we processed the material, screened it and stockpiled it. Also, a portion of the backfill will consist of about 30,580 m³ (40,000 yd³) of concrete that comes from recycling almost 100% of the building.”
Getting the materials to the ground where they can be separated takes more than just knocking it down with a crane and wrecking ball. With safety a concern, Gramercy laid out a plan to take the stadium down in sections, first by cutting the steel supports then pulling the sections down with large hydraulic excavators. Once it’s on the ground, the company sorts and separates materials, mostly using late-model Komatsu machines Gramercy purchased from Edward Ehrbar Inc., one of Komatsu’s distributors in the U.S., with the assistance of Mr. Dan Stanton, sales rep of Ehrbar, and Mr. Lawrence McCrann, vice president of sales.
Versatile Komatsu Hydraulic Excavator
“We have eight Komatsu hydraulic excavators working on site, including a PC800 and a PC600 that we’re using to pull the sections down,” said Mr. Parziale, who also has PC400 and PC200 hydraulic excavators on site, as well as three Komatsu WA480 wheel loaders. “A job like this requires versatile equipment, so all our Komatsu excavators are equipped with quick couplers to swiftly change to buckets, shears, hammers and grapples.
“It’s not always feasible or cost-effective to have multiple units on site, so having one machine with the power and capability to handle several tasks is a distinct advantage,” he added. “That’s the case with Komatsu.”
KOMTRAX Indispensable for Maintenance
Using Komatsu’s KOMTRAX wireless machine tracking system is another advantage, according to Mr. Parziale, as both Ehrbar and Gramercy monitor the company’s Komatsu equipment for hours, location and other essential functions.
“KOMTRAX allows us to more accurately track our maintenance and service, which is essential,” said Mr. Parziale. “It ensures services are done on time, which in turn means the equipment maintains its production and uptime. Ehrbar does a great job of monitoring our machines as well, working with us to quickly handle any issues, such as a fault code. It’s that level of service from Komatsu and Ehrbar that convinced us to try Komatsu in the first place. Anything we need, they’re right there to help, and that hasn’t always been the case with other distributors.”
