Chelmsley Wood Shopping Centre was constructed in the late 1970’s and comprises a number of predominantly single storey retail blocks. The shopping centre benefited from a £40 million extension and refurbishment programme in 2009 which saw it anchored by an ASDA superstore. In 2019, a £2 million refurbishment project of the public realm was completed with the installation of a public square alongside landscaping and street furniture.
The centre benefits from a good representation of national multiple retailers including Wilko, Iceland, JD Sports, Sportsdirect, Poundland and Boots. There are also a number of local independent traders and a covered market. Many local government services such as Job Centre and the library are located in the scheme which makes it a hype of activity with shoppers and workers on a daily basis.
The town is a relatively new area, which was built by Birmingham City Council in the late 1960s and early 70s on ancient woodland, once part of the Forest of Arden, as an overspill town for Birmingham. The forest has a rich history and this is celebrated annually with Chelmund Day consisting of parades of mythical characters who once spanned this part of the Midlands. The town benefits from excellent road connections and can be accessed by rail via Marston Green station which provides a direct service to Birmingham New Street and Coventry.
The diagnosis and treatment of a range of conditions is set to get quicker, thanks to a new centre in Chelmsley Wood.
NHS Birmingham and Solihull Integrated Care Board and University Hospitals Birmingham NHS Foundation Trust are opening a new Community Diagnostic Centre (CDC) in Chelmsley Wood, in partnership with InHealth, the UK’s largest specialist provider of diagnostic solutions. The new centre will open to patients in Spring 2025.
With funding provided by NHS England, thousands of people will be able to visit it every year to get a wide range of diagnostic tests in one central place, away from a busy hospital site. The services will be for the use of the populations across North Solihull and the greater Birmingham area.
The large archetype North Solihull CDC will be the first of its kind in Birmingham to be located in a retail location, situated at the shopping centre in Chelmsley Wood. It will offer high tech scanning, including MRI, CT, Ultrasound and Xray, as well as Endoscopy other Health Screening services, helping to detect a range of conditions quicker, ensuring patients can then be treated faster. Patients will be able to access the services via a clinician referral.

The existing Building was constructed in the 1970’s and was occupied by Jacob Douwe Egberts (JDE) – coffee manufacturers as part of a wider site development. The building has since been separated from JDE and is a standalone site. The building was refurbished in 2019 into an industrial unit.
Existing System:
The existing fire alarm control panel is in the main entrance to the building. This required interfacing with the new fire alarm systems. The fireman’s override switch is be located adjacent to the main entrance.
New system:
The system has been designed and is generally in accordance with the British Standard 5839 Part 1: 2019 category “L1” and incorporates:
The new system is a Gent Vigilon 1-4 Loop Addressable Fire Alarm complete with integral battery backup. This is installed in the main Warehouse adjacent to the door to the Hub office. There is also a repeater panel located within the Guard house.
All devices are loop powered, including all beam detectors.
The Internal lighting system is mounted on a 40amp Bus bar system. The lighting is controlled with built in PIR detection within each fitting. The lighting is set to activate for 3 minutes and then 10% for 1 minute and then will turn off. The light fitting are set up into groups so when one light fitting is activated all fittings within this group will be illuminated. The emergency lighting form an integral part of the high-level lighting with emergency bulkhead to each escape door.
The external lighting consists of building mounted lighting and column mounted lighting The lights are controlled via a time clock located adjacent to the relevant distribution boards and also via a local photocell. The cabling to the external lighting column is installed in an underground cable ducting system. The power supplies to the building mounted fitting are installed within containment within the existing building.
The existing building is supplied by a 1600 Amp LV switch board with an 800 Amp incomer (NS800N). This supplies the current installation which consists of the office block, office hub, warehouse, the external lighting and the fire alarm. Installation of a new sub main cabling is installed from existing LV switch panel to the new ATS. Additionally, a new sub main was installed to the distribution board from the ATS. This distribution board will be purely for the power supplies that are required for the smoke system, as listed below:
It should be noted that all new cabling will be BS7846 standard as minimum. The specific requirements for armoured fire-resistant cables with thermosetting insulation – 600/1000V- with low emission of smoke and corrosive gases when affected by fire. The following options was selected:
The existing building is supplied by a 1600 Amp LV switch board with an 800 Amp incomer (NS800N). This supplies the current installation which consists of the office block, office hub, warehouse, the external lighting and the fire alarm.
An extension panel has been added onto the existing panel to provide a new power supply to the new smoke vent switch panel. As part of these works, load monitoring has been added to allow for load shedding of power supplies when the demand for power for the smoke vent system is getting close to the maximum limit.
A Lightning protection survey was carried out on the existing building. Following this survey, our team installed a new lighting protection system. There are various lighting protection points around the building. There are also 4 number lighting and protection points installed around the backup generator for the smoke vent system with a recorded reading of less than 1 ohm. This is connected directly to the backup generator.
Mealey Electrical designed a smoke system strategy for Amazon Logistics- Southam Road, Banbury, OX16 2DJ. DOX2 is an existing building which was redeveloped in 2019. The building has a footprint of approximately 18,300m2. The building comprises of a single storey warehouse (van storage) with ancillary office facilities. The primary office is located on the eastern side of the warehouse and is located on the first floor only. A smaller two storey (ground plus one) hub office is located on the southern side of the site.
System descriptions:
Specifications:
The system has been designed and is generally in accordance with the British Standard 5839 Part 1: 2019 category “L1” and incorporates:
A Gent Vigilon 1-4 Loop Addressable Fire Alarm was installed, complete with integral battery backup, full qwerty keyboard, printer, and RS232 output for connection to the BMS. This is within the main entrance of the building.
All devices are loop powered, including all beam detectors.
Fire Alarm System – Interfacing:
In the event of a fire condition the system may be required to operate/shutdown various items of equipment. This is achieved by volt free contacts, using loop powered interfaces and relays, as follows:
Cause and Effects:
The beam detection and call points are all to action a full evacuation of the fire alarm system.
Special programming multi-detectors in the warehouse area were installed as part of the pre-action sprinkler system.
Warehouse multi-detectors are programmed into zones to match that of the sprinkler system, splitting the warehouse in to 3 zones.
Fire alarm system (Existing):
The existing fire alarm control panel is located in the main entrance to the building. The existing system was interfaced with the new system. The fireman’s override switch is located adjacent to the main panel.
Under normal conditions mains power is supplied from DNO to power the LV switch panel through the ATS to the essential systems connected to the distribution board.
In the event of a mains power loss the backup generator will energise and power the essential LV distribution panel. The ATS will move from normal power supply conditions to loss of mains condition.
A 600KVA prime rated generator complete with 1250 Amp ATS was installed. The generator is located to the external of the building. The generator has a sound and weatherproofing canopy constructed from high quality steel plate, fitted with a residential exhaust muffler and base fuel tank.
The cabling from the generator into the building was installed in underground ducting and is terminated into the 1250 Amp ATS located inside the building adjacent to the main panel board. A control cable was installed in the ducting from the generator to the ATS control panel. This will energise the generator on mains failure. In turn, the ATS will switch from mains to generator backup. The generator will then power the smoke system when the normal power supply is lost.
A section has been added to the existing panel. This is a MCCB which was added to supply the Smoke vent switch panel. Due to the size of the existing power supply a load monitoring system was added in an event of the maximum damage being exceeded. Before this happens, power supplies will be shut down, so the available power is used for the smoke vent system in the event of a fire.
See below pictures of the completed works.

Mealey Electrical contractors were instructed to carry out the refurbishment of a first-floor open plan office area where individual meeting rooms were created, along with reception and kitchen areas. Mealey Electrical were employed in a sub-contractor capacity.
The works consisted of modifications to the existing lighting as per the new office plans. The existing movement sensors located in the ceiling were used to operate the lighting in the open plan areas whereas switches were used in the meeting rooms. Small power to all areas consisted of new Dado trunking installed above the desks to allow for easy access to the socket outlets. Existing circuits were retained in around the perimeter of the offices, with additional socket outlets added. TV locations were installed to the meeting rooms and reception area.
Door access system was installed to the reception and rear emergency exit door which are operated via keypad and fob. The system is also linked to the fire alarm system and will release in the event of a fire. The existing fire alarm was altered/added to in order to accommodate the new meeting and office area layout and then commissioned.
Throughout the duration of the contract communication between the client and Mealey Electrical was efficiently maintained, enabling the successful completion of the various installations/ modifications on time.
Mealey Electrical Ltd. were commissioned to carry out the refurbishment of Ward 34 at Glenfield Hospital. Mealey Electrical were employed in a sub-contractor capacity.
The mandate for the job consisted of removing the existing bedhead trunking in 6 bays and installing new bedhead trunking in 7 bay locations.
The existing small power circuits were isolated (LOTO) and reconfigured when the new trunking was installed. New inspection lights were also installed to each bed location. The existing main lighting above the beds remains in place but the switching needed to be moved into the new bedhead trunking. This was accomplished by discussing the requirements with the manufacturers of the trunking system and a switch was provided within the trunking at various locations.
The contract was carried out over a very short period of time, with a deadline to adhere to, which we were able to complete to the client’s satisfaction. Testing and commissioning were carried out during the installation and at the final stages.
