46 • ROCK products • February 2019 www.rockproducts.com W hen the aggregates industry experienced a few tough years one limestone quarry not only survived those hard times, but thrived – by focusing on the future in a site planning partnership with Volvo Construction Equipment (Volvo CE). Delta Companies Inc. is a site development and highway con- tractor specializing in asphalt paving and road construction materials, including aggregates. Delta operates five quarries and a sand and gravel pit. One of those quarries is located in Cape Girardeau, Mo., near the Mississippi River. The Delta SEMO Quarry in southeast 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 1 million ppy from a 200-acre property with an open pit that is now more than 400 ft. 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 rela- tionship Colas has with Volvo CE 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 CE Key Accounts Solutions team dispatches specialists to review all aspects of a site opera- tion. 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 prioritized list of recommendations, which the cus- tomer can factor in to its immediate and strategic plans. Delta worked closely with Volvo CE to explore how to reduce costs and make its SEMO 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. Taking the (Over)Burden Out of Mining While SEMO 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 CE, and Craig Griffiths, manager of customer solutions at Volvo CE – 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 oper- ating a new Volvo EC750E recently delivered to SEMO. This work complemented the day-to-day support provided by Volvo CE dealer Rudd Equipment Co. Delta Looking Further Than Ahead Delta Companies Forges a Visionary Partnership That Boosts Quarry Uptime.
