Maternity Generator replacement

The University Hospitals Birmingham NHS Foundation Trust wish to replace the existing low voltage diesel driven 255kVA rated Maternity Standby Generator at Heartlands Hospital with a new higher rated low voltage diesel driven 500kVA rated prime rated low voltage diesel driven generator set. The new 500KVA low voltage diesel driven generator shall be housed in the current Maternity Generator House.

In addition to the above, the project works shall also to entail the following associated with the new Maternity low voltage diesel driven standby generator: -Remove and replace existing fuel pipework and connections from the existing low voltage diesel driven bulk fuel tank to the new standby generator, the existing fuel storage tanks shall be retained and re used under these works. -Provide & Install a new suitably rated floor standing Low Voltage Switchboard -Provide new manual transfer switch to select between the new Maternity Standby Generator and temporary generator connections. -Provide a temporary generator connection facility in suitable housing for the Maternity Block -Provide a temporary load bank connection facility in suitable housing for the Maternity Block -Provide load bank shedding contactor arrangement to disconnect Maternity Generator load bank supply upon main failure to enable the embedded generator to support the essential load. The location for the new low voltage diesel driven Maternity Standby Generator is as noted on the drawings.

New automatic generator controls will be provided for the for the new low voltage diesel driven Maternity Standby Generator to ensure the generator supports the load on a mains failure within timescales prescribed within this document. The associated low voltage switchgear works comprise the supply and install of a new Low Voltage Switchboard and facilities for connecting a temporary resistive load bank for generator routine "on load" testing and connection of a temporary low voltage diesel driven generator should the embedded low voltage generator need be taken "off line" or fail. This project also includes all associated building works in the provision of an external lockable GRP Enclosure and a suitable base, installation of below ground cable ducts and making good / sealing penetrations on completion of the works.
