Project Overview

Arnold Lodge is a medium secure psychiatric hospital situated in Leicester, England, run by Nottinghamshire Healthcare NHS Foundation Trust. It was opened in July 1983 and an extension with 30 extra beds was opened in 2007.

Our solution

Waldeck were involved in the reinforcement of the existing 500KVA low voltage electrical infrastructure to 800KVA at the existing Arnold Lodge site.

The reinforcement, includes a new REC 800KVA substation, new 1200A rated main LV switchgear to the site together with a new 800KVA packaged standby generator set installation and all interconnecting LV cabling, whilst the Health Unit remains fully operational.

A priority for this project was to ensure that the work being carried out on the LV supply reinforcement did not affect the operation of the health unit. Not only did this include the need to cut off the main electrical supply to the unit to upgrade the Supply Authority switchgear, there was also a requirement to keep the unit car park accessible as the switchgear was located within the car park.

Waldeck provide Principal Designer services to the Trust during the design stage of the project.

The final design included for the sequencing of deliveries so that the existing stand-by generator could be used to provide power to the unit while the Supply Authority switchgear was replaced and commissioned. Once completed the new up-rated stand-by generator was brought in to replace the existing.

Minor changes were made to the car park layout during the Supply Authority works to ensure that staff and visitors had access to the car park during the up-grade works.
