About Us
Landmark Construction Services, Inc. was established in Sterling, Colorado in 1983. Company founder and president, Stephen O’Neal, was quick to realize the economic potential of Sterling and surrounding areas and began his business servicing the growing agricultural and suburban markets. As the area thrived, Landmark Construction kept pace and today is proud to be the largest contractor in Northeast Colorado. Our services and abilities are extensive, and include pre-engineered steel buildings, manufacturing facilities, retail and bulk storage buildings, warehousing and repair facilities, farm storage, grain handling and feed mill facilities, post-frame buildings as well as re-roofing services for existing structures.

Just a year after the company was founded, Landmark Construction Services, Inc. became associated with Butler Manufacturing—the world’s premier manufacturer of pre-engineered building systems. As a member
of a select group of authorized Butler Builders, Landmark Construction provides the highest quality of pre-engineered building systems available today. Since Butler Manufacturing has consistently led the industry in product development, our association with Butler has given us the competitive edge we need.

Landmark Construction Services, Inc. specializes in design-build commercial and industrial projects. The design-build approach to construction offers distinct advantages over traditional methods. Design-build simplifies the building process allowing both design and construction professionals to work as a team. This single-source of responsibility results in more accurate communication and more reliable cost estimates with fewer changes. Fewer changes mean projects are completed on time and within budget.

In 1983, Landmark Construction's staff consisted of just seven individuals. Today we have 49 employees, some who have been with us for as long as 20 years. Our current staff represents a full range a capabilities from office support to craftsmen, engineers, construction administrators and project managers. We support and encourage the professional growth of our employees and firmly believe in advancement from within the company.

As Landmark Construction Services, Inc. continues to grow and plan for the future, a strong commitment to quality guides each and every project we undertake. We are particularly proud of the relationships we have maintained with past customers—some of whom have become repeat customers. We are a results-oriented contractor with a sincere commitment to exceed our customers’ expectations. When you add the Company’s superb safety record to Landmark Construction's commitment of quality and integrity, you get the largest and most reliable general contractor in Northeast Colorado and surrounding states.
