CPR completed resurfacing works to Platform 1 of Kings Park Station in Glasgow, on behalf of Network Rail, which required the use of a 70m crane to lift materials into the station.
The project commenced in February 2016 and took almost 8 weeks and 200 man hours to complete. The works consisted of approximately 180 m of copes being lifted and replaced, with the lift and relay of tactiles and surfacing works.
CPR’s Rail Division Processes
CPR’s in-house Track Access Team planned the works at Kings Park Station 10 weeks in advance and in conformity with Network Rails On or Near the Line Standard NR/L2/OHS/019.
In addition to this, the process of obtaining permission from multiple agencies including; NWR Structures; Glasgow City Council Road Closure Permit; Glasgow City Council Crane Permit; Glasgow City Council Environmental (Noise) Notification; Traffic Management; Abnormal Loads Street Works and OLE Isolation, was also successfully completed in-house prior to the works commencing.
CPR’s in-house Safety Critical Team successfully carried out Possession and Line Blockage arrangements throughout the duration in order to allow the works to safely proceed and be complete.
70m Crane Requirement
The additional processes outlined above were required because due to poor access to the station platform in consideration of the materials and equipment required. This factor therefore required the use of a 70tonne Mobile Crane which was positioned on the overhead bridge (Kings Bridge Drive) to hoist approx. 45 pallets of copes (and supporting materials) and 1-ton Excavators from road level to platform level over a distance of 31m metres.
Scope of works.
The approach in this project, aside from the requirement of the crane to move materials onto the site, was normal and a regular operation for the Rail Division team.
To remove the existing cope with a stone magnet (SWL 400Kg) attached to a 1-ton excavator within an Exclusion Zone. The CPR Rail Division team have a number of mechanical and safety certifications to allow the teams to work in the rail environment.
The team then broke out the existing concrete bed and brickwork using a 110v Breaker and laid new brickwork here required. The Stone Magnet (SWL 400kg) was then used to replace existing using 1220 x 930mm special Copes. 2 x hand-held Stone Magnets were used to position and make minor adjustments to the copes once they have been placed on the mortar bed. Cope levels were set from the existing levels based on the heights and off-sets of the existing platform.
The Tactilies stage of the process was undertaken by the lifting and removal of existing tactiles and debri, and a Cat scan of the surface was undertaken to prepare the area for surfacing.
The required layers of surface were imported and laid using a ride on roller and whacker plates, then the edges sealed using hot liquid bitumen to prevent water ingress at the joints.
