ISG is an international construction services company delivering fit out, construction, engineering services and a range of specialist solutions. Our consistent delivery across geographies makes us the partner of choice for multi-national and local organisations building, refurbishing or fitting out their spaces. We are also focused on the communities where we work – employing local people and building networks of local suppliers. Whether we are working on small, bespoke works, or a large-scale project of global significance, our focus is on setting the standard for construction services. Central to this is our commitment to consistency which helps us to deliver predictable outcomes for our customers, regardless of their building type, location or the sector in which they operate. That is why both international brands and small, local organisations trust us to deliver their spaces on time, at quality and on budget. Our customers include owners, developers and occupiers in all sectors. But not everything about us is predictable. In fact we are known for our innovative approach, commitment to a more sustainable future and also for employing the most talented and collaborative people.
