Landmark EPC has deep roots in Northern Colorado, stretching back to 1969, when the firm was originally founded as Hogan & Olhausen by Dale Olhausen and Ron Hogan. Focused on civil engineering, surveying, and planning, the company quickly built a reputation for technical excellence and hard-earned field knowledge.
By 1975, the firm had expanded its capabilities with its own in-house drill rig, launching a geotechnical services division that remains a cornerstone of the company’s expertise.
In 1978, Landmark became one of the first survey firms in the region to adopt the HP 3820 electronic total station, cementing its place on the leading edge of data-driven field engineering.
Following the departure of Ron Hogan, the company was restructured and rebranded as Landmark Engineering Ltd. in 1982. From there, Landmark grew steadily—adding geotech, soils testing, and structural engineering services—while relocating operations to larger facilities along Eisenhower Boulevard in Loveland, Colorado.
In 2002, founder Dale Olhausen sold the firm to a group of key employees, marking a transition in leadership but not in values. The company remained independently owned and operated for nearly two more decades, continuing to serve municipalities, energy clients, and developers throughout the Rocky Mountain region.
Since 1969, our team has helped shape Northern Colorado with practical solutions and trusted engineering insight. What began as a civil engineering and surveying firm has grown into a respected name backed by decades of on-the-ground experience.
In 1975, we introduced in-house geotechnical services with our own drill rig—marking a pivotal step in our growth. Today, that same division continues to be a key pillar of our integrated engineering approach.
Back in 1978, we were among the first in the region to embrace electronic total station technology. That early adoption set the tone for our commitment to innovation and precision in every project.
In 1982, the firm became Landmark Engineering Ltd., marking a fresh era of growth and expansion. With new service lines and a move to larger facilities, our footprint—and capabilities—continued to scale.
When ownership transitioned to a team of key employees in 2002, our core values stayed firmly in place. For nearly 20 more years, we remained independently owned—delivering trusted solutions across the Rocky Mountain region.
In 2020, Landmark Ltd. joined forces with Energy Solutions Corp, becoming Landmark EPC. This transition marked a bold new chapter—expanding our reach while honoring the legacy that got us here.
Today, Landmark EPC is a full-service Engineering, Procurement, and Construction (EPC) firm, delivering turnkey infrastructure solutions across the Mountain West.
While our name and scope have grown, we still carry the same boots-on-the-ground ethic and problem-solving DNA we were founded on in 1969.
Safety is at the core of everything we do at Landmark. With zero TRIR and certified safety programs, we ensure every project protects our team, clients, and communities. No job is ever too urgent to be done safely—and done right.
