JSE-listed engineering and construction group Murray & Roberts (M&R) expects to growth its order book beyond the current level of R60-billion on the back of growing demand for its services. “Over the next three years, the group expects most of its revenue to be generated by its two international business platforms, being the mining and the energy, resources and infrastructure platforms,” M&R said in a business update released to coincide with its seventy-third annual general meeting.
