Our Renewable Discipline focuses on Balance of Plant (BoP) construction in both the wind and solar sectors of this industry and draws on the various other disciplines the Stefanutti Stocks Group offers.

Our broad spectrum of expertise, our strong solution-based culture and our capacity across the construction environment enables us to offer a single point of responsibility on multidisciplinary energy infrastructure development projects, effectively removing the interface risk from these type of projects.

Our engineering, civils and general construction capabilities span bulk earthworks, piling and geotechnical, building and management, ME&I (mechanical, electrical & instrumentation), structures (including specialized steel structures) and civils. We also offer an in-house BIM 4 and 5D planning and execution capability.

excellence in execution

Stefanutti Stocks’ in-house MEP capability and know-how means that we have the experience to either manage specialist subcontractors, on behalf of our clients, or in fact complete all ME&I and structural steel work in-house. We also have our own in-house pipe-spooling fabrication facility. This in-house MEP capability also means that we can both price and execute the structural steel, electrical and mechanical disciplines in house, thereby offering our clients a complete one-stop solution.

Pre-cast towers for Nxuba Windfarm SS

Pre-cast towers for Nxuba Windfarm

During 2019 Stefanutti Stocks Civils Discipline manufactured pre-cast concrete towers for the Nxuba Wind farm in Somerset East, Cape Province. The prefab facility, constructed by Stefanutti Stocks, included two sixty-four-ton gantry cranes, rebar jigs, hydraulically operated moulds and a full-equipped concrete laboratory on site. The self-compacting concrete met BSI1 Standards and achieved a concrete compressive strength of 80 Mpa at twenty-eight days and 25 MPa at sixteen hours, or at eight hours with heat curing. The supply chain was managed carefully to ensure long lead time products procured abroad, arrive prior to being required.
