Big projects need the right equipment, the right support, and the right partnerships.
Recently, STM was on site with BY Group at their Marsden Park project, a large-scale data centre development in north-western Sydney.
Over the past seven years, BY Group has continued to grow in the civil earthworks and construction space, and STM is proud to have supported that journey with reliable machinery, practical advice and strong after-purchase service.
On this site, the combination of Kobelco SK135 excavators and Hydrema dumpers is proving to be a strong fit for the work at hand. With the SK135βs zero swing design, strong lifting capacity, fuel efficiency and Tier 3 no AdBlue engine, it is well suited to detailed work in tighter areas. Paired with Hydrema dumpers for efficient spoil removal and excellent manoeuvrability, it is a setup built for productivity.
A big thank you to Lyall Harris and the BY Group team for their continued trust in STM.
Weβre proud to be partnered with businesses doing great work across Sydney and beyond.
