PROJECT CHALLENGES:
Uninterrupted hospital services; carefully planned and managed phasing of works; additional loading onto original structure
Rooftop support structures and a road gantry to facilitate the upgrading of hospital heating infrastructure
Carefully planned and managed phasing was essential in this scheme, to ensure that the hospital’s services continued without interruption.
Deteriorating existing tunnels, limited of road and path space and complex services below ground meant it was necessary to design structures to support large diameter pipework across existing roofs, and by gantries between hospital buildings. Analysis of existing roof structures concluded that columns and foundations had insufficient structural capacity, so steel frames were created to transfer additional loadings onto existing structural columns.
A steel bridge was established between the boiler house and maternity blocks, crossing an internal access road. Careful phasing was required to minimize road closures, and at appropriate times. This gantry was designed for possible additional future loading. Suspended pipework within the boiler house required back analysis of the existing steel portal frame.
Construction of foundations for a new oil storage tanks required careful sequencing to avoid undermining adjacent structures or interrupting the plant’s operation. Autotrack was employed to design an efficient yard slab for oil delivery vehicles. All drainage was integrated with the existing system.
