Guys Hospital

DESCRIPTION

The project involved the design, tender and implementation of a complete new replacement of the Guys Hospital site 11kV generators to support the Hospital High Voltage infrastructure for the Site at London Bridge.

The project involves the replacement of the existing 3x 2000kVA generators with 3no 3600kVA generators.

DESIGN

Working within a congested delivery area of the Hospital, this project is one of the most challenging briefs undertake by Eta Projects Ltd.

Detailed load analysis was undertaken of the UKPN local network. The design included for the acoustic   analysis and other specialist controls and monitoring packages.

The project has expanded into the detailed design for the extension to the 21-section HV switchboard to accommodate additional feeders from UKPN and the provision of dual supplies to the new Cancer Centre.

OBJECTIVES

Guys Hospital was supplied via three 20-year old 2000kVA generators which were undersized to support the new developments on site namely the new £300M Cancer Centre.

Eta Projects Ltd were instructed by the Trust to undertake the detailed design and project management for the tender and implementation works associated with the new generator replacement works.

The works were tendered on the OJEU (Official Journal of the European Union) open tender portal and Finning UK, part of the Caterpillar group were successful in winning the tender.

SPECIFIC DESIGN REQUIREMENTS

Due to the architectural layout and congestion of the site, the existing generator rooms are congested with both Electrical and Mechanical ventilation equipment. The ventilation and cooling of the new generators was
a major challenge.

A specialist acoustic consultant was engaged to ensure the noise level is not increased above the level of the original noise level. This project is underway and due for completion in March 2015.
