In preparation for another Important/Critical Network Rail Relay room, J Gunn Scaffolding are working with Colt Construction who are in partnership with Network Rail this building that needed work due to the water ingress due to the aging building.

J Gunn Scaffolding erected a full designed system independent scaffolding to the full perimeter of the relay room and a full static Haki roof system that was near the track side with all the correct PTS trained operatives to instal this type of work.

J Gunn Scaffolding have the required scaffolding accreditation as well as the ISO accreditation (9001, 14001 & 45001) with a rigours audit annually, also 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 this relay roof, we had to ensure that the critical buildings would be weather tight.

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, this was due to the critical work that the relay room does for Net Work Rail. The relay room 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, safe operation of trains and access and egress to the Kings Cross Station.
