When founded in 1968, Harrison Western brought superior design and construction services to the mining industry. A few years later, the firm expanded to offer civil and above ground construction services. The company has set North American shaft sinking records through major aquifers, and was the first contractor to introduce earth pressure balance technology to the tunneling industry. Today, with more than 45 years and over $2 billion in construction, mine development, engineering and process development, Harrison Western leads the industry in safety and performance. The geographic range of projects ranges from the Arctic to the Andes. Harrison Western combines the expertise of our experienced staff with hands on management to ensure projects run smoothly and cost efficiently.
