15 Years Lake Lorraine
Signature Project Timeline
A 15-year project transformed a sand excavation site into Lake Lorraine, a mixed-use development.
The company quickly evolved under Warren Friessen's hands-on leadership.
Typical projects include large-scale site development, excavation, asphalt reclamation, concrete work, demolition, utility installation, material hauling, and seasonal snow removal.
Ownership passed to the founder’s daughter, now President Cynthia Monnin, who continues the company's regional focus while steering multi-acre developments.
Financially rooted in steady local government and commercial contracts, the firm supports mixed-use residential and commercial builds alongside infrastructure work.
