Collaboration improves limestone quarry performance

Jon Lawson

The aggregates industry has had a few tough years in the United States but is now recovering. One limestone quarry not only survived those hard times but thrived – by focusing on the future in a site planning partnership with Volvo.

Delta is a site development and highway contractor specialising in asphalt paving and road construction materials, including aggregates. It operates five quarries and a sand and gravel pit. One of those quarries is located in Cape Girardeau, Missouri, near the Mississippi River. The Delta Semo Quarry in South East Missouri has been a leading supplier of limestone to the local construction industry for more than 40 years. Semo typically produces between 700,000 to one million tons a year from a 200 acre property with an open pit that is now over 400 feet deep. It is a solid business with ample reserves to keep serving customers for decades to come.
 
Delta knows its business and has a plan for the future but was not satisfied with that. As a subsidiary of the Colas Group, Delta can leverage benefits from the special relationship Colas has with Volvo as a global key account customer. One benefit is access to the manufacturer’s site assessment program provided by its Global Key Accounts Management team.
 
In this program, the Volvo Key Accounts Solutions team dispatches specialists to review all aspects of a site operation. The team provides a deep analysis of current and future business, lifts up best practices and uncovers potential areas of improvement. This is an extended dialogue that concludes with a prioritised list of recommendations which the customer can factor in to its immediate and strategic plans.
 
Delta worked closely with Volvo to explore how to reduce costs and make its operation even more efficient. Taking a closer look at the customer’s machine fleet is just one aspect in the complimentary site assessment program. Drilling, blasting, crushing, stockpiling – all were included and considered during the team’s one-week site visit. They also looked at safety practices, site layout, business planning, reserves planning, environmental aspects and maintenance practice.

While operations were running well, little tweaks were suggested to boost things further. The assessment team – led by David Nus, Director of Global Key Accounts at Volvo, and Craig Griffiths, Manager of Customer Solutions at Volvo – focused on an overburden project already underway and suggested ways to develop and maintain work benches and haul roads in an efficient and safe way.
 
Other suggestions included aspects of maintenance and fleet management for their mobile fleet, as well as tips for operating a new Volvo EC750E recently delivered. This work complemented the day-to-day support provided by the Volvo dealer, Rudd Equipment.
 
“Our main role at Volvo is to sell mobile equipment, but that’s not our only role,” said Nus. “In these site assessments we want to be able to add value to our clients’ operations, highlight what’s important and advise organisations how to think strategically for the future. If Volvo can contribute in any way to a customer’s success, we become more than just a supplier, we are a true business partner.”

Semo is using a new Volvo EC750E excavator as a primary loader for its overburden removal though it does serve in limestone production as well. The excavator loads rigid dump trucks as well as articulated haulers, including a Volvo A40D articulated hauler that dates back to 2005 and boasts over 16,000 hours. The site assessment works well because it advises customers on the best way to use machines like these, to ensure the equipment is appropriate for the job at hand.
 
The findings from site assessment vary from client to client. Some require more input in the day-to-day operations on site, while others are looking for ways to maximise future profitability. By taking the time to really understand the dynamics of a business, like Delta, Volvo is not only able to help its customers improve their operations but also improve the way Volvo designs and plans its own machines and services to maximise uptime.
