Leeds Train Station Critical Works

J Gunn Scaffolding have erected a 1200m2 working platform at Leeds Train Station. The 26 scaffolding towers were designed and built based upon the location of the main arches that hold up the main station. The towers were also hoarded as security to prevents access. Unit beams span across the full area to create a floating platform. Fire proofed boards are doubled up, and a flame retardant membrane is between. It allows 24 hour work on the working platform.

A HAKI rolling roof system was also built on the outside of the train station. The roof system was designed to prevent any water egress. Crucially, it could be opened and close at any time. This was to allow old steel work to be removed and new steel work to be installed to keep the work continuing at all times.

The station remained open at all times during the erection of the scaffolding. In fact, the works were designed to avoid any disruption to the public, ensure safe operation of trains, and maintain access and egress to the station at all times. A time lapse video was produced to showcase our work.

Luton Relay Room

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.

Major roof repairs to Grade 2 listed Filey Train Station

J Gunn Scaffolding worked with Colt Construction, who are in partnership with Network Rail, on new major roof repairs to the Grade 2 listed building at Filey Train Station.

J Gunn Scaffolding erected fully designed independent scaffolding to the full perimeter of the train station. It also had to bridge over the rail tracks at both sides of the building for roof repairs.

A 1800m2 scaffold crash deck was also built with design from RV Engineering, The crash deck was designed by bolting the scaffolding to the walls with very minimal scaffold on the platform due to the platform size. Shear and pull tests were done to demonstrate the weight calculations could hold the scaffolding crash deck.

The scaffolding has a 60-minute fire rating with mechanical ventilation and natural ventilation for train exhausts.

The station remained open at all times during the erection of the scaffolding. The project has been designed to avoid any disruption to the public, allow safe operation of trains, and retain access and egress to the station including maintaining Fire Escapes at all times.

Major shed roof repairs at Grade 2 listed Scarborough Train Station

In preparation for major train shed roof repairs at Grade 2 Listed Scarborough Station, J Gunn Scaffolding are working with Colt Construction who are in partnership with Network Rail.

J Gunn Scaffolding has erected a 2500m2 scaffold crash deck. The scaffolding has a 60-minute fire rating. It also features mechanical ventilation and natural ventilation for train exhausts requiring a complex fire modelling system.

The station remained open at all times during the erection of the scaffolding. The access has been designed to avoid any disruption to the public, allow safe operation of trains, and maintain access and egress to the station, including maintaining Fire Escapes at all times.

Upon detailed examination of the Victorian-made platforms, significant voids were found to be present. These received mass pour concrete to fill. In addition, there were loose ground conditions. They required a strengthening solution that could provide ground support for a load of 100kN/m2 to 36 scaffold towers before work could begin.

PROJECT DETAILS

J Gunn Scaffolding were asked to provide Safe Access and Egress to various Network Rail Signal boxes within the UK. Due to weathering to the listed buildings, the work was to provide a scaffolding service that allowed for a full refurbishment of the Signal boxes to take place.

Working in partnership with RV Engineering, J Gunn Scaffolding undertook a site visit to a number of Network Rail Signal boxes to understand the full scope of work – starting with the Hexham and Wylam Signal boxes.

CAD Drawings of the Signal boxes were produced by RV Engineering. The task given to J Gunn Scaffolding was to safely erect complex scaffolding which required to be built around the building and spanned with 750- and 450-unit beams across the railway line, allowing the refurbishment to commence whilst the train lines remained in full use.

To enable the work to be completed safely, careful planning was required, resulting in a number of rail line closures and night shift working. An onsite supervisor led the team safely, completing the work without any incidents or accidents.

The project was safely completed in 5 nights, ahead of schedule, and within budget. J Gunn Scaffolding provided a scaffolding inspector for the project. The scaffolding inspector sits outside of the team, and independently inspects the scaffolding, checking for defects.
