About Grozdanic Group
A family of Alberta companies with one standard: do the work right, deliver on time, stand behind it.
Grozdanic Group is a family of Alberta companies serving industrial, commercial and residential customers across Western Canada and beyond: Tiger Machining Inc. (precision machining and compressor sales & service, Sherwood Park and Edson), Add-Val Contracting (full-service electrical contractor, Edmonton) and Adam Crane Ltd. (crane rentals and lifting services, Edmonton & Sherwood Park).
Our story
Grozdanic Group grew out of Tiger Machining Inc., a Sherwood Park machine shop serving Alberta's energy and industrial customers. Add-Val Contracting was founded in 2011 to bring the same standards to electrical work, and Adam Crane Ltd. added crane rentals and lifting services. Today the three companies share leadership, safety systems and back-office, while each keeps its own crews, customers and trade expertise.
