Engineering, whether the building of a car, an aircraft, a bicycle or a building - single or multi-storey, requires that calculations are made, understood, and applied. Materials, their choice and application, as well as the methods used, maintenance and monitoring are essential in the safety of all. Everybody is involved in safety and the future of each construction - here we see a safety conscious construction site in the city. Safety is a culture, it takes time to embrace, and it is growing in West Africa. Slowly, but it is growing. Recent events raise our awareness - but now we must apply what we have learned at an individual level - right down to every materials supplier, every worker, every supervisor as well as regulatory oversight matters - in all areas of construction and engineering.
