Omagh Hospital & Primary Care Centre

Doran Consulting has been commissioned by the Western Health & Social Care Trust to provide civil, structural and traffic engineering design services and CDM Co-ordination for this scheme to develop an enhanced local hospital in Omagh. The new hospital will provide a range of primary health and social care facilities including GP accommodation, Out Patients Department, Renal Department, a Children’s Department and specialist care.

A general outline of the design of the main buildings is that they are 3-storeys in height with a semi-basement in one block and M&E plant accommodation located at rooftop level. The facilities are in linear configuration with a series of blocks arranged around a central courtyard and connecting corridors. Non-clinical accommodation such as car parking, an energy centre, sterilisation and maintenance buildings, laundry and staff changing, is also included.

The project is divided into four phases, with Phase 1 concerned with obtaining Statutory Approvals, ground modelling, widening and upgrading an existing road and provision of a site accesses, footpaths, street lighting, services diversions and landscaping works.

Phase 2 is concerned with civil aspects, in particular drainage, with the separation of the site sewerage into dedicated storm and foul systems, demolition of existing waste water treatment works and connections to NI Water sewerage network and the River Camowen, including all necessary statutory approvals. The decommissioning of the existing treatment works and associated drainage works proved to be particularly challenging as these works had to be sequenced so as to keep the existing facilities in use at all times, ensuring that the new drainage lines were available for connection of building outfalls prior to the old lines being abandoned.

Phase 3 is concerned with the demolition of 8 buildings following the completion of asbestos surveys, grubbing up of foundations, retention of stonework and decommissioning of redundant connections. Phase 4 involves the provision of a new link road for site access and a new bridge to cross the River Camowen, the design of which involved flood modelling and compensation works. This last part has posed a significant environmental issue as the river can flood and is also periodically home to a large salmon population. Therefore the road works adjacent to and over the river provided for flood compensation measures and terms of work to protect the salmon.
