Keeping Dublin Airport moving ✈️

CJK completed a 12-month mechanical infrastructure upgrade at Dublin Airport, replacing LTHW and CHW pumping systems across multiple Terminal 1 plantrooms.

Working in a live airport environment, our team carefully phased shutdowns and system isolations to replace and recommission critical heating and cooling infrastructure while minimising disruption to ongoing airport operations.

Another complex project delivered by our mechanical team in a challenging live environment. 👏

Protecting hands on site ✋

Almost one in four non-fatal injuries in construction involve the hands or fingers - a reminder of just how important hand safety is on site.

As part of our ongoing focus on safety and continuous learning, teams across a number of CJK sites recently took part in Toolbox Talks with Hilti Ireland focused on hand safety and Hand-Arm Vibration (HAVS).

The sessions looked at the risks associated with using both power tools and hand tools, covering everything from vibration exposure and correct tool selection to hand positioning, appropriate PPE and safe working practices.

It was a practical opportunity for our teams to look at how the right tools, equipment and working methods can help reduce the risk of hand and arm injuries in their day-to-day work.

Thanks to the Hilti team for delivering the Toolbox Talks and to everyone who took part.

Another great few days at WorldSkills Ireland! 🤩

It was great to meet so many students at WorldSkills Ireland last week and chat about apprenticeships, life at CJK and the opportunities available through CJK Academy.

The buzz wire was back again this year and, as always, brought out plenty of competition!

A brilliant event for showcasing apprenticeships and giving the next generation an insight into the different career paths available across the industry. 🙌

Thanks to everyone who stopped by the CJK stand!

CJK x Barnardos | Finglas Family Fun Days 💚

Our CJK volunteers recently joined Barnardos Ireland for two Family Fun Days in Finglas, helping out at Meakstown Community Centre and St Helena’s Resource Centre.

The events brought local children and families together for games, arts and crafts, entertainment and lots of fun, with our volunteers lending a hand throughout.

CJK’s Volunteer Day gives our people the opportunity to take paid time to support a charity or community initiative. It was great to see some of our team using theirs to support our partnership with Barnardos and get involved in the local community.

A big thank you to everyone who volunteered and to the Barnardos teams for having us.

The Paul Hatton Hike in Support of Coolmine TC 🙌

On Friday, 31 hikers from CJK, Coolmine and our clients took on a 30km trek through the Wicklow Mountains, raising over €20,000 for Coolmine Therapeutic Community and its vital treatment and rehabilitation services for people in recovery from addiction.

This year’s hike had special significance as, in memory of our great friend and colleague Paul Hatton, our annual Coolmine hike became The Paul Hatton Hike.

Paul was at the heart of CJK’s relationship with Coolmine for many years. He believed in people, recognised their potential and worked tirelessly to create opportunities for people in recovery. He was also part of this hike from the very beginning and never missed one, so it feels fitting that it will carry his name from now on.

A huge thank you to everyone who took part, generously donated and helped make the day possible.

Recent Project Completion | EV Bus Charging Infrastructure ⚡️🚌

CJK recently completed the electrical works for a major EV bus charging infrastructure project, supporting the transition to a fully electric bus fleet.

The project included the installation and connection of four 200kW pantograph bus chargers, the first of their kind to be installed in Ireland, along with seven 150kW EV chargers across two locations.

Our scope also included two new purpose built substations, MV infrastructure and a new load management system to remotely monitor the charging infrastructure and manage electrical demand.

The completed infrastructure provides a reliable and efficient charging solution, supporting the client’s move towards lower emission transport.

Well done to the CJK team involved. 👏

CJK Golf Scramble 2026 ⛳️
