The River Cole is located within the southernmost section of the Delta Junction, a triangular section of High Speed Two (HS2) Phase One, where the route curves west towards Birmingham…

The St Mary’s Field Museum programme of events demonstrated that it is not only safe and secure to invite members of the public on to a construction site, but that…

The paper aims to discuss the advantages and disadvantages of the double composite section in high-speed railway bridges from the design, construction and maintenance point of view. The paper is…

The main objective of the railway drainage system is to manage surface water and groundwater to the level of service required to ensure the continual and safe operation of the…

The “Traction Substation package” for HS2 comprises the construction works for the relocation of an existing London Underground Ltd substation on the corner of Drummond Street and Melton Street. The…

There is limited guidance for pile design in the Mercia Mudstone, when it varies between a weathered stiff clay and unweathered weak mudstone. In this transitionary zone, it is common…

Project: Provision of a series of customer focused Virtual Reality Simulation sessions for the Phase One and 2a hybrid Bill Design, commissioned as part of two Passenger Experience and Landmark…

High Speed Two (HS2) is a catalyst for growth across the UK. Along with this comes not just environmentally responsible landscape and ecological design but, offers a once in a…

As part of High Speed Two (HS2)’s Innovation programme, a trial of alternative fuels was carried out in partnership with the Centre for Low Emission Construction at Imperial College London…

A 450m long retained excavation to a maximum depth of 18m close to sensitive 3rd party assets will be constructed to house future HS2 tracks north of Euston station. Approximately…

Viaducts structures are assets adopted in High Speed Two (HS2) to minimise the impact of the railway on the existing motorways, watercourses, and other low-lying developments. The design of surface…

The HS2 Birmingham Interchange Station has been located to provide connections to multiple transport modes and routes. It is surrounded by major roads and situated close to Birmingham Airport and…

The Colne Valley Western Slopes (CVWS) is one of the largest and most significant environmental projects on the High Speed Two (HS2) Phase One route and represents a synthesis of…

An essential part of managing whole life carbon impacts of High Speed Two (HS2) Euston Station is quantifying, monitoring and reporting whole life carbon emissions through a Life Cycle Assessment…

The management and delivery of environmental surveys on a scale as large as High Speed Two (HS2) is an inherently complex challenge. Within HS2 Phase 2a, contractors have been working…

The investigation and accurate characterisation of weak rocks can be extremely challenging when fracturing and weathering creates difficulties in sampling and testing from boreholes. One such material is the Mercia…

High Speed Two (HS2) aims to re-use a minimum of 95% of soils generated by the scheme. This poses challenges for the re-use of potentially contaminated materials. In support of…

The High-Speed route joins the West Coast Main Line at Handsacre Junction just North of Lichfield, enabling HS2 Phase One services to continue North to Crewe and beyond. All High…

The High Speed Two (HS2) mainline crosses deep cuttings in Charmouth Mudstone. Deep excavations cause significant stress changes in the ground which inevitably result in ground heave. However, there is…

EKFB-JV will build the Cut and Cover ‘Green Tunnels’ (GTs) as part of the Main Works Civils Contract (MWCC) for the central section of High Speed Two (HS2) Phase One.…

This paper focuses on a novel process maturity framework developed during the targeted improvement to the Integrated Design Review and Assurance (IDR&A) Process, by the Skanska Costain STRABAG (SCS) Joint…

The proposed 3.4km long Colne Valley Viaduct provides an excellent opportunity to review and optimise design methodologies for large diameter bored piles within Chalk. Whilst piles have been successfully designed…

The HS2 project is delivering built infrastructure and natural environments on an unparalleled scale. The project affords a once in a generation opportunity to deliver nationally significant infrastructure that will…

With over 21 million cubic metres of material (equivalent to 8,400 Olympic swimming pools) earmarked to be excavated and moved across the 90 km of the northern section of the…

HS2 tunnels will pass below an existing main line railway intersection bridge near Euston, known as Bridge 7, constructed in the early 20th century. An assessment of tunnelling induced ground…

The latest London Atmospheric Emissions Inventory published by the Greater London Authority, indicated that Non-Road Mobile Machinery (NRMM) is a significant source of air pollution. This poses health risks and…

Ground Movement Assessments (GMAs) involve analysing and mitigating the damage caused by construction related ground movement on strategic utilities, operational tunnels and historically important buildings. Gaining approval from owners of…

This paper describes the process of planning and managing completion and handover, in particular the importance of starting at the early stage of a contract, defining processes, requirements and deliverables…

We have worked extremely hard to create a collaborative relationship with HS2, ensuring continued focus on the needs of both delivery partner and HS2, and creating a common approach and…

Previously, the permit system was aligned to traditional construction sites or rural areas. The team had to adapt certain aspects of the process, to ensure work could be undertaken safely…
