The integration of EARTHRES and RESPEC has expanded how the combined companies serve clients in the mining and energy sectors, particularly in the design and construction of aggregate processing plants. These plants are crucial components in producing construction materials. RESPEC’s expanded expertise offers innovative and comprehensive solutions that address the industry’s most complex challenges.
Greg Rauhauser, a Senior Project Manager, highlights how EARTHRES’s capabilities bring tremendous value to clients. “We handle every phase, from evaluation to operation,” Greg explains. “We can conduct exploratory drilling to assess deposits, navigate permitting processes, develop mine plans, perform detailed market research to determine the most viable products for a given location, and design processing facilities to optimize their production.”


RESPEC’s independence from equipment manufacturers distinguishes its approach. The team selects the best equipment for each project without ties to specific brands. “We don’t represent any manufacturers, so we’re free to design systems that truly meet our clients’ needs,” says Mike Garard, a new member of the RESPEC team, who has many years of experience in the design, fabrication, erection, and commissioning of aggregate processing plants. This unbiased perspective also fosters innovative problem-solving, such as repurposing existing equipment for new applications—a creative edge that sets RESPEC apart.
The key team members, including Greg and Mike, use advanced tools like AggFlow software to create precise flow diagrams to guide equipment selection and improve production efficiency. Whether the material is sand and gravel, limestone, granite, or basalt, RESPEC ensures plants can process the extracted material for the intended end use—concrete, asphalt, or cement/lime plant feed. By aligning plant design with market demand, clients benefit from facilities that optimize the production of salable products, reducing waste and maximizing profitability.
The combined strengths of RESPEC and EARTHRES offer more than technical capabilities—they provide a streamlined experience.
The benefits extend beyond design expertise. RESPEC’s team takes a comprehensive view of plant functionality, emphasizing operational efficiency and ease of maintenance. This client-centered focus often translates to reduced downtime, increased productivity, and significant cost savings. Based on his years of plant design and construction, Mike notes, “When maintenance is easy, plants stay online longer, which means they’re making money instead of sitting idle.”


RESPEC’s integration with EARTHRES also expands its geographic reach, enabling the company to serve a many clients across North America. RESPEC applies its extensive industry experience to deliver solutions that align with each client’s unique goals, from multinational corporations to stand-alone aggregate producers. The services include a full range of support to the industry, such as de-bottlenecking, upgrading, or designing plants. RESPEC provides aggregate processing experience from the crusher to the customer.
The combined strengths of RESPEC and EARTHRES offer more than process design capabilities—they provide a streamlined experience, including structural, mechanical, and electrical design services consolidated under one roof. Clients enjoy a single point of accountability throughout the project. This approach ensures projects remain on schedule, within budget, and aligned with operational needs.
RESPEC is redefining plant design for the aggregates industry. The company’s ability to integrate forward-thinking design with hands-on industry knowledge creates unparalleled value for clients, paving the way for long-term economic success.
