In preparation for another Important/Critical Network Rail Relay room upgrade, J Gunn Scaffolding are working with Colt Construction who are in partnership with Network Rail. The building needed work due to water ingress because of the ageing structure.

J Gunn Scaffolding erected a fully designed system of independent scaffolding to the perimeter of the relay room. We also installed a full static Haki roof system. It was challenging to work near the track side, but we have the correct PTS trained operatives to install this type of work.

J Gunn Scaffolding have the required scaffolding accreditation, as well as the ISO accreditation (9001, 14001 & 45001), with an audit annually. We’re also qualified with CISRS and HAKI roofing systems.

J Gunn Scaffolding have successfully delivered a large number of high volume, high value and critical works such as this type of work. To allow the removal of the relay roof, we had to ensure that the critical buildings would be weathertight.

The HAKI roof system is designed to prevent any water egress upon opening and closing this roof system. The old roof was removed and lowered and a new roof installed. It was a vital project due to the critical work that the relay room does for Network Rail; it controls the track points in the main Kings Cross station.

The relay room was monitored and remained open at all times during the erection of the scaffolding and has been designed to avoid any disruption, ensure safe operation of trains, and maintain access and egress to the Kings Cross Station.
