This project, which took place during the construction of a new laboratory facility at the University of Bristol, involved planning and installing a completely new lighting and electrical system for the building. The installation included a new 650 amp sub mains distribution system (with emergency shutdown facility), cable management systems, LED lighting and power installations, as well as emergency lighting and fire detection systems.

An assignment of this size is primarily about project management; we had to make sure that everything happened when it should, to prevent the building process being held up by our team of electricians.

Having good communications with the other contractors enabled us to stay up-to-date with any changes in the direction of the project, as well as helping us effectively time-manage our work load. Effectively working with the other contractors on this project ensured that it was completed on time and within budget.

Our routine annual safety check of this airfield (primarily used for micro-light flying, parachuting and skydiving) brought to light a few electrical faults, which we set about resolving. The facility is fairly unique from an electrical point of view, as due to the remote location it is powered entirely by a 12-volt battery.

The main issue was that, due to changes in regulations, the location of the battery was no longer deemed as safe and secure. To overcome this problem we relocated the battery into a secure enclosure and installed a safety cut-off key, as well as an MCB (miniature circuit breaker).

With this work completed, as well as a number of other minor electrical issues that we resolved, we were able to provide the airfield with their electrical safety certificate for another year.

Whilst attending this service station to carry out a periodic test and inspection, we found a few faults. In order to resolve these electrical issues, we carried out the following investigations, repairs and upgrades:

• Renewing of the mains distribution, which enabled us to fit double pole RCD’s to the circuits.
• An investigation into high diverted neutral currents.
• Two TN-C-S supplies fitted into one metal building, creating an electrical feed for two shops.

This sort of job highlights the importance of your annual electrical safety checks, particularly in hazardous areas like this petrol station.

The manager was reassured to know that we had uncovered these faults and potential issues, and was happy to have his service station registered as ‘electrically safe’ for another year.

This particular job involved installing illuminated advertising signs in all but one premier league and first division football stadiums in the UK.

Each stadium required the installation of 20 – 30 signs, so managing the delivery and distribution of these units was key to the success of the job.

Once we had the signs on site, we arranged and mounted them in the desired locations, installed and connected electrical supplies, and finally tested them and installed the relevant advertising media to each sign.

The job was a big success, please check out a few pictures of the work we did at Everton Football Club:

We provide an installation, breakdown and maintenance service to the concrete industry. One of the plants that we have recently provided a full new electrical installation for is this facility at Callow Rock Quarry.

One of the key issues that we dealt with whilst working on this project was the compact nature of the build, which was ground-up and had to be constructed within an existing footprint.

We have a team of electricians who are experts at this kind of installation. They were able to work with the designer and the construction team to come up with an electrical set-up that is perfect for the facility.

The resulting plant is fully computerised and caters for both ready mix deliveries and customer collections. Check out a few pictures of the new installation below:

We were called out to asses an MRI unit that had been experiencing some electrical failures. We managed to diagnose the problem quickly, and set about separating and modifying the circuits, and adding full RCD protection.

Our fully qualified electricians ensured that all work was carried out in line with MEIGaN Standards, and they provided the hospital with documentation to this effect.

Since the completion of this electrical upgrade in2013, the unit has had no further failures, so hospital staff have been able to continue with their work uninterrupted and without inconvenience to their patients.
