Howard Electrical completes prestige London hospital contract   

Martin Read – Business Reporter

Faygate’s Howard Electrical specialises in all aspects of electrical and mechanical engineering and has just completed a prestige, intricate and highly demanding contract at London’s St Mary’s Hospital. The plantroom in the Clarence Wing at the Imperial College Complex in Paddington required complete upgrading by replacement of the two outdated existing plantrooms with the installation of a new state of the art, fully automated Low Temperature Hot Water facility.                                                                                                                       The two original plantrooms and associated mechanical plant had long surpassed their expected life cycle and were beyond economical repair, the new plantroom being required to provide more efficient heating services to the wards within Clarence House, overlooking Praed Street. 

Equipment from major specialised manufacturers was sourced, including heat exchangers, pumps, a pressurisation unit, expansion cylinders, valves and strainers. 

Family owned and run, Howard Electrical is an independent company with over 30 years of dedicated experience in the provision and installation of bespoke electrical engineering, priding itself with its coveted reputation for reliability, high quality work and excellent customer service, Director Peter Howard says: “Access to the rooftop plantroom was just one of the challenges that our team had to overcome. In order to access the work area safely, a scaffolding structure was erected from the ground floor to roof level. Health and safety was paramount throughout the project.”

The two-story plantroom was delivered on two wide-load lorries out of business hours to ensure traffic was at its quietest on the busy surrounding London streets. On a Saturday, the plantrooms were crane lifted over the building and lowered into position within the courtyard area.

Circuits were stripped out and capped for future connection to the new plantroom, and new pipework was run from the nearest steam and condense mains to serve the new plantroom and the new heat exchangers, with all work configured to a high industry installation standards. 

Removal of the two existing plantrooms, one on the hospital roof and the other at lower level within the courtyard, each containing associated equipment, was a complicated procedure at the restricted site. A major requirement throughout the work was the continuation of the heating services to the hospital’s Winnicott Baby Unit, where environmental conditions are critical. Iain Radford, an HVAC engineer at Howard Electrical, commented: “Precautions were taken to ensure all communications were kept open to CBRE and ward nurses. The specialist nature of the hospital activities meant that we had limited time for necessary isolations and shutdowns, but we managed to supply supplementary heating throughout.”                                      Project Manager Alan Blackman-Noakes of major provider for the health sector, CBRE said: “The new installation was a highly complex project completed in a very tight timeframe. Howard Electrical exceeded all expectations and worked in a highly professional and efficient manner. The plantroom is now fully operational and delivering heating to the Clarence Wing.”

He added: “Disruptions were kept to a minimum and were fully planned and communicated so that the hospital could continue delivering its own service to the public in London. I will be using Howard going forward on the next plantroom project due to their highly professional conduct, quality of management and workmanship.”
