Why GP Group invested

GP Group saw an opportunity in 2011 to rekindle its construction play after Christiani & Nielsen had completed a corporate rehabilitation. The Group is focusing on strengthening the firm’s engineering, procurement and construction (EPC) capabilities and capacity to provide design-and-build turnkey services in various sectors like infrastructure (roads, highways, airports, etc), industrial (factories, warehouses, petrochemical plants, etc) and other types of buildings (residential, hotels, retail malls, hospitals, etc).
