Tender: Construction of Full-Length High-Level Access Platforms – Allerton Depot (Northern Trains)

About

Northern Trains Limited is seeking a supplier for the construction of full-length high-level access platforms at Allerton depot based on designs from RCA Construction to enable safe working at height along the entire length of four-car trains. The platforms will be installed on one road to improve operational flow in the Planned Heavy Clean (PHC) area and must be compatible with existing fleets (Classes 323, 768 and 331) and any future fleets at the depot. Required features include barriers, fall protection systems, appropriate signage, and a safe method for removing roof-mounted components such as HVAC units while minimising manual handling risks. The platforms must integrate with existing overhead line equipment (OHLE) isolation systems and the depot protection system so they cannot be used unless the overhead electrical supply is fully isolated. Works will be supplied under a JCT Intermediate Works with Contractors Design 2024, and the contract may be novated or assigned to Train Operating Companies or DFT Operator Limited or a successor parent company; Northern Trains reserves the right not to award and will not be liable for suppliers' costs.
