Project details

The new emergency centre at New Cross Hospital was part of a £30m major healthcare upgrade to bring all emergency services, that were spread out across the hospital site, under one roof. The scheme was funded under the ProCure21+ framework and provided additional capacity, a new A&E department, wards and admin space.

  • Client: Kier Construction
  • Project: Accident & Emergency Centre at New Cross Hospital
  • Location: Wolverhampton
  • Sector: Health
  • Value: £2.5m
  • Service: Groundworks


The construction of the new Accident & Emergency centre at New Cross Hospital, Wolverhampton involved sewer diversion, new storm and foul drainage, foundations, ground and upper floor slabs and external works.

The foul and storm drainage diversion and the new storm attenuation tank were possibly the hardest and most complex element of the works. It involved diverting the live foul and storm drainage system of a busy working hospital. The installation of the  new storm drainage and attenuation tank involved installing a 30m long by 2.5m diameter tank (145,000l), 5.5m to invert,  adjacent to a live ambulance laydown area, with the ambulance having a 4m access and about 1m away from our work area . This blue route as it was known had to be kept open at all times.

The sub-structure element for the construction for the new A & E centre included all the foundations (mass fill bases and RC pile-caps) and a 3300m2 ground floor slab, all the below ground foul and storm drainage, LV switch room/substation and service trenches and all external finishes including ramps and steps to the entrance. Retaining walls were also required to close off an existing underground tug-way route (an underground access route for small hospital vehicles moving materials) while maintaining the access and movement  for the hospital “TUGS”.

The upper floors are composite slab construction which means casting concrete on metal decking with reinforcement. The 1st and 2nd floors with an area of 3300m2 each  were cast and the 3rd floor / roof with an area of 800m2 was concreted with a  power floated concreted finish.


“We have been very impressed with the professionalism shown by O’Brien in all areas from the help and assistance they provided pre contract, through to planning, rationalising of scope and execution of all their tasks on site. This is the first time we have worked with O’Briens, but we already consider them a key member of our supply chain and
we will benchmark our other groundworkers against their performance.”
