Case Study Imperial College Healthcare NHS Trust Charing Cross Hospital - East Wing Power Monitoring July 2019
As part of a power distribution upgrade project at Charing Cross Hospital, Imperial College Healthcare has recently upgraded its Essential and Non-Essential Power Supply power that feeds East Wing Riser C floors LG – 7th.
The ‘Essential’ and ‘Non-Essential’ rising bus-bar systems that served the Tower Block East Wing Riser C were out-dated and operating beyond their design life. In addition to this, the change-over panel that served the risers and distribution equipment was of non-IP2X construction, had suffered water ingress, showed signs of deterioration and was generally in poor condition. Therefore, it was proposed that the Tower Block East Wing Riser C Section One, ‘Essential’ and ‘Non-Essential’ bus-bar systems, associated feeder change-over panel, floor distribution panels and trunking were replaced. The new power distribution equipment needed to include BMS monitoring to alert Estates staff of any faults within the system.
The BMS integration involved the monitoring of each MCCB open, closed and tripped volt free status signals from terminals located within each tap off unit. BMS Integration was also included for the Asta certified change-over panel and ASCO change-over system.
The new BMS control system included the following;
Brand new purpose-built control panel
New control wiring to a purpose-built marshalling box
The latest Trend IQ4 Controllers
Network connection between the BMS panel and the BMS “network”
New dynamic graphics pages
NDA Consulting was involved in the design and specification of the project ensuring co-ordination with the M&E Consultant, ETA projects. NDA also provided implementation stage support which included:
Checks & comments on BMS contractor tech-subs, drawings, software and graphics
Check installation & attend progress meetings
Attendance at final on-site witness tests with Eta including report
Attendance at hand-over meeting to Estates
Checking of contractors Draft and final O&M’s
Making sure that the BMS and controls complied with the BMS specification and the installation was completed to a high standard.
