Mitton Healthcare Case Studies
The Institute of the Sisters of Our Lady of Mercy Convent, Yeadon, Leeds
The Institute is one of three strands of the Mercy family in Great Britain. It is formed from the union of twenty autonomous Congregations, and was formally recognised as a Religious Congregation of Pontifical Rights in November 1983. Currently there are three hundred and forty eight Sisters ministering from seventy-five sites in Britain. Sisters also work in Peru, Kenya, Rome and Romania.
The project at the Institute’s convent in Yeadon, Leeds involved the provision of a new, low pressure hot water heating installation within all occupied areas of the first floor of the building, utilising a new 2-pipe, pipework installation and new radiators. This work also incorporated some alterations to the new heating installation at ground floor level.
In addition, the boiler house was repiped incorporating new pipework, valves, fittings and equipment, creating an installation capable of working effectively with a zone control, and facilitating the integration of a new automatic control system.
Additional works included modifications to the existing gas installation, the hot and cold water services installations and revision of the arrangements for dispelling the products of combustion into the atmosphere.
Resolving Nursing Home Water Issues
At Well Springs Nursing Home, a home for the elderly and infirm, Mitton has designed, installed, tested and commissioned new water systems serving individual areas of the building. These systems use mains fed pressure calorifiers which ensure the equalisation of pressures at the thermostatic mixing valves. Mitton has also provided additional secondary return pipe work to eliminate long ‘dead legs’. along with new secondary circulating pumps to ensure the system meets with all the requirements laid out in the Legionella code of practice.
Through Michael Hall of Hall & Hoyle Architects, Mitton first carried out a thorough survey of the existing water services installations, and found that additional systems had been provided as the building had been expanded over many years. The resulting problem of adding all these systems was an imbalance of water pressures at thermostatic mixing valves. This has now been overcome by Mitton’s design and installation.
The installation was carried out over an eight week period, fully co-ordinated by the on-site staff to ensure that interruption to services was kept to a minimum. The project was completed on time and to schedule.
Additional storage facilities have been provided to the kitchen area, as the original installation was fed from a much smaller system which was regularly flattened by the kitchen demand.
Mr Redhead, owner and manager of Well Springs, is extremely satisfied with both the installation provided and the performance of Mitton. and is confident that the design now installed has proved beneficial to the working of the Home.
In Safe Hands at Care Home
Following an evaluation process involving RAH & Associates, and a competitive tender, Mitton were commissioned to carry out alterations and modifications to the existing water services installations at McAuley Mount Care Home in Burnley.
The contract called for necessary alterations to existing hot and cold water services installations to provide mixed and safe water temperatures at all outlets used by residents within the care home. These points have now been equipped with thermostatic mixing valves complete with isolating valves, double check valves and strainers limiting water temperatures to 43oC, eliminating the chance of any scalding occurring to old and infirm residents.
Mitton also replaced an indirect hot water storage calorifier, renewing automatic controls including a three port valve arrangement and temperature sensor. New isolating valves were provided and installed on all branches from the mains distribution pipework so that isolation of bedroom blocks could be achieved without the need for total isolation of the hot and cold water distribution installation.
The installation was carried out over a four week period and was successfully handed over towards the end of December 2007, complying fully with the client’s initial request. The inspecting engineer is said to be delighted with the work carried out by Mitton.
Community Loan Store - Kirklees Primary Care Trust
Mitton has developed significant experience and understanding of the changing needs of community loan stores in terms of decontamination/sterilisation processes.
Working with RAH & Associates and main contractor Peter Armitage Building Contractors Mitton has completed water services modifications to facilitate this process at Kirklees PCT’s Huddersfield location, including installation of a new water storage tank and boosted cold water system, ventilation, thermal insulation and automatic controls.
Contract Value: £25,000
Huddersfield Royal Infirmary
Maintaining consistent temperatures and achieving optimum operational efficiency is a key issue for public buildings. Mitton has completed a major project on behalf of Calderdale & Huddersfield NHS Trust to replace steam/water calorifiers with plate heat exchangers at Huddersfield Royal Infirmary.
Carried out over two phases during the summer months, when demands on heating are significantly reduced, Mitton removed the original steam water calorifiers and installed modern plate heat exchangers capable of supplying both heating services and hot water. The project has not only increased plant efficiency but also removes the need for stored water in compliance with Health & Safety and Legionella requirements.
The project involved the installation of new steam and condensate pipework, low pressure hot water heating, hot and cold water services, automatic controls, electrical works and thermal insulation.
A total of 10 new plate heat exchangers were provided and installed to replac three DHWS storage calorifiers and eight non storage calorifiers, providing benefits in terms of energy efficiency and physical space in the plant room.
Contract Value: £370,000
