Arsenal Station: – Subway Flooring

Project: Arsenal Station – Subway Flooring

Client: Tube Lines Limited

Works Value: £416,000

Our works to replace the non-compliant flooring at Arsenal Station were completed 9 weeks ahead of programme.  This was made possible by the close co-operation between JNP, D&D Rail Ltd, LUL Management and Station Staff.  With agreement from LUL Station Management, our site teams were able to work during station closures and Traffic Hours due to noise abatement issues at Arsenal.  These works were carried out in hoarded areas, inside an acoustic tent and behind acoustic and chapter 8 barriers.

This project was undertaken under our framework contract for Tube Lines Limited (Minor and Intermediate works).

The existing flooring tiling in the passageways was found to be non-complaint due to de-bonding and slip resistance issues.  Our work scope therefore removal of the existing floor tiling, screed and concrete sub-base over an area of 500m2.  The floor area was then brought up to the required level with Parex concrete and re-screeded prior to laying the new flooring.

300 x 300mm2 concrete pavers were then laid over the full 500m2 in a sequence which allowed a safe surface for passengers during the works.

We also removed and replaced all of the existing access covers and retiled the interiors.  All existing drainage channels were pressure washed and cleaned out and new drainage covers fitted.

Finally there was a requirement to ensure that there was sufficient clearance below the Crowd Barriers and the new pavers.  To facilitate this the Crowd Barriers were removed and welded back at the correct height to allow sufficient clearance.
