HMP Buckley Hall, Boiler Plant Replacement

The project was located at HMP Buckley Hall and comprised of new boiler and domestic hot water plant replacement works. The Mechanical Engineering Services installation comprised the following systems:

• Gas fired heating and domestic hot water.
• LTHW heating services.
• Domestic hot and cold water services.
• Building management system.
• Temporary plant installation.
• Testing and Commissioning.
• As fitted drawings/operating & maintenance manuals.
• Builder’s works in connection.

The existing gas fired boilers, water heaters and buffer vessels, associated flues, system pumps, pressurisation and expansion plant, pipework and BMS controls system was completely stripped out and replaced with new. Temporary heating and domestic hot water plant was provided for the duration of the works.

Prior to commencement of detailed design works a Low/Zero Carbon (LZC) technologies feasibility analysis was undertaken to determine if any appropriate LZC or renewable energy systems could be accommodated within the constraints of the project scope of works.

The analysis concluded that due to the nature of the site, restricted plantroom access, limitations of the existing structure and the spatial restrictions within, this would not permit the installation of new LZC internal or external plant, such as an air source heat pump or bioenergy boiler systems.

The proposed boilers are therefore ready for 20% hydrogen blend and it is stated by the manufacturer that they will be certified for 100% hydrogen. This proposal fulfils the requirements of MOJ Sustainability Guidance: Fossil Fuel Fired Heating Plant Replacement.

Where applicable, all relevant MOJ Property Directorate Technical Standards were adhered to.

HMP Shower Refurbishments at various sites

The existing showering facilities were of inadequate standard. The scope therefore was to provide the maximum number of cubicle shower outlets for the given space and to comply with the MOJ shower specifications.

Where applicable, all relevant MOJ Property Directorate Technical Standards were adhered to. All specified items were suitable for use within establishments including the use of anti-ligature fittings, fixtures, security rated grilles and louvres.

It was the MOJ intention to strive for sustainable development and introduce energy saving devices in all upgraded related refurbishment. Energy saving devices were actively introduced in to the projects as part of the design in all cases, including the likes of heat recovery, LED lighting and occupancy sensing.

The projects posed a series of challenges to the design in respect to the spatial requirements of the new ventilation plant and equipment that were needed to be installed within existing limited services voids and cupboards. Generally, the new ventilation plant and equipment were larger and needed more space due to improved performance compliance requirements.

Associated electrical connections, controls and power wiring were also designed as part of the projects.

HMP Manchester

Humphrey M&E Consultants are pleased to assist Amey Projects with various works at HMP Manchester.

Humphrey M&E Consultants have assisted Amey Projects with preparing a condition and strategy report for the main boiler room replacement scheme.  The scheme initially consists of replacing the 4No gas fired boilers followed by the replacement of the domestic hot water system calorifiers and heating circuits serving the accommodation wing.

HMP Lincoln

HMP Lincoln is a Category B prison holding male adult prisoners located at Greatwell Road, Lincoln

Humphrey M&E Consultants are working with Amey Projects to deliver works associated with Legionella Risk Eradication within the prison domestic water services system.

The initial phase of this work involves the refurbishment of the Central Boiler House, replacement of the district heating mains and the installation of 3No bespoke packaged plant rooms.

The Boiler house contains 2No 4500kW Winter boilers and 2No 1750kW Summer boilers. It is estimated that over 1,700 linear meters of district heating pipework will be replaced as part of the works.
