Leeds Train Station Critical Works

J Gunn Scaffolding have erected a 1200m2 working platform, the 26 scaffolding towers where designed and built, based upon where the main arches that are under the train station are that hold up the main station. The 26 towers where horded as security to prevents anyone accessing the towers. Unit beams span across the full area to create a floating platform with fire proofed boards doubled up and a flame retardant membrane between to allow 24 hour working on the working platform.

A HAKI rolling roof system was also built on the outer of the train station. The roof system was designed to prevent any water egress and this roof system 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 and has been designed to avoid any disruption to the public, safe operation of trains and access and egress to the station at all times. A time laps video was produced

Luton Relay Room

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.

Major roof repairs to Grade 2 listed Filey Train Station

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

J Gunn Scaffolding erected a fully designed independent scaffolding to the full perimeter of the Train Station that also had to bridge over the rail tracks at both sides of the building for roof repairs.

A 1800m2 scaffold crash deck was also build with design from RV Engineering, The crash deck was designed by bolting the scaffolding to the walls with very minimal scaffolding on the platform due to the platform size. Shear and pull tests where 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 requiring complex fire modelling system.

The station remained open at all times during the erection of the scaffolding and has been designed to avoid any disruption to the public, safe operation of trains and 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 have erected a 2500m2 scaffold crash deck. The scaffolding has a 60-minute fire rating with mechanical ventilation and natural ventilation for train exhausts requiring complex fire modelling system.

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

Upon detailed examination of the victorian made platforms significant voids were present and these received mass pour concrete, in addition to the loose made ground conditions, which 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 lead 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.
