Defined by hard work and client dedication for more than three decades

Conwest Contracting was founded by John and Tony Marinelli in 1985. Having previously worked with their father in residential utilities contracting, the brothers established Conwest to expand upon their family values of hard work and perseverance, building a new platform from where they could demonstrate their client-forward focus. Since the company's inception, John, Tony, and business partner Ben Taddei have expanded Conwest Contracting into one of BC’s leading civil contractors.

The Conwest team offers exceptional insight and attention to detail whether working on an advanced specialty project or one that brings them back to the basics. Their experience, knowledge, and entrepreneurial attitude allow them to effectively deliver a wide range of projects across the Lower Mainland.
