Project Description

The proposed HS2 Phase 2b western leg extends the line to the north-west, to Manchester with connections to the West Coast Main Line at Crewe and south of Wigan. It is approximately 85km of new high-speed railway with new stations at Manchester Airport and a terminus station adjacent to the existing Manchester Piccadilly Station.

The works include extensive surface railway sections on embankment and in cutting, 15km of viaducts, 19km of bored tunnels under Crewe and into Manchester, major motorway crossings, a shallow box station at Manchester Airport and a major above ground station at Manchester Piccadilly.

LBA Role

LBA provided the Mott MacDonald/WSP Joint Venture with all aspects of construction and logistics planning required to support the Environmental Statement (ES) and submission of the hybrid Bill to Parliament for the whole of the route. This included:

  • Construction planning and methodologies.
  • Construction programme.
  • Mass haul earthworks strategy and distribution.
  • Selection of worksite locations and areas.
  • Definition of construction boundaries and land requirement.
  • Determination of construction data for input into the ES and project planning including plant and equipment requirements, worker numbers, demolition schedules and construction site services.
  • Determination of traffic routes and vehicle predictions.
  • Technical support in engagement with stakeholders and the public.

This information included comprehensive reports, with relevant detailed tabulated appendices, or specific topic technical notes.

Support was also given to all disciplines within both the Engineering and Environmental teams, to provide relevant construction data to support the ES, construction input to the designs and value engineering, and input to the risk and assumptions registers.

The construction programme was produced in both Gantt format and as a Time-Chainage diagram, together with a summary programme used for Quantitative Schedule Risk Analysis.

In addition to the construction planning role, LBA also provided costing support, particularly expert knowledge for the more specialist elements such as tunnels, shafts and associated infrastructure.

Project Highlights

LBA provided comprehensive experience-based design and construction knowledge to support the joint venture in the production of the ES for the hybrid Bill. By providing this hands-on experience and knowledge, the project benefitted from optimisation of the designs and value management as the scheme developed and the timely provision of essential data for the ES.
