CampbellReith has been appointed to assist the Mechanical, Electrical and Public Health Engineers to provide Structural and Civil Engineering services related to the Infrastructure upgrade of the existing services on the large Queen Elizabeth hospital estate.

As part of these works there is a wholesale upgrade of the existing Energy Centre and Fuel tank space, which is being adapted to house new equipment required to more efficiently support the hospital facilities. Our works involve evaluation of the existing building structures, and design of new structural support should the proposed plant exceed the capacity of the existing structure.

We have also advised on new mezzanine steel frame to expand the capacity of the existing plant space. Our solution has looking to support the mezzanine frame on the existing ground floor slab and foundations where this is within the existing capacity. However, where this has not been possible, new pad footings have been incorporated.

Due to the extensive loading of the proposed 4m high water tanks to be housed in the existing building we have proposed a piled raft for support inn these areas. We have looked at the access within the confines of the existing building and we have advised on using mini-piles for these works.

Adaptation of the existing fuel tank space has required a further mezzanine frame to provide a level threshold with the external ground level as the existing floor is a storey height below the ground. We have been able to provide efficiencies in the design by spreading the new floor load above the reduced level slab. Avoiding any breaking out of the existing substructure as part of the works.

There are also several elements of equipment being placed on the existing roof across the hospital estate, typically the roof capacity is insufficient for the proposed loading. Therefore we have designed new steel support frames to span over the existing roof and transfer this load directly into the existing columns and foundations. We have been able to obtain extensive record drawing information to enable the load assessment to be carried out.

We have also been involved in Civil’s work at the hospital estate looking at the adaptation of the existing access roads onto the site. All of the works are taking place in a live hospital environment and therefore the phasing of the construction and impact on hospital adjacencies has been considered with the Trust through the design process.
