St Pancras Hospital, Mary Rankin Unit, 1st Floor Ophthalmology Department

Summary of Project:

The Ophthalmology department in the Mary Rankin building required the design, coordination and installation of mechanical and electrical services as part of the improvement works that were going on. The supplied areas comprised of four consulting rooms, a waiting area, a reception, an injection room, a laser room, a retinal image room, an Orthoptic room and a fields room. The works also required a particular emphasis on the detailed design coordination of all of the individual building services because of a relatively low ceiling void. The provision of a fully coordinated detailing between the building services and the various building/architectural/structural components was also needed.
