Landscape earthworks form a major design element on the HS2 project, integrating and screening the railway and infrastructure within the landscape. These earthworks are a critical component of the scheme,…

A review of construction activities within High Speed Two (HS2) construction sites determined that haul roads are a major contributor to fugitive dust emissions, and can have significant detrimental effects…

Balfour Beatty VINCI Joint Venture (BBV) is contributing to the “cleaner, greener future” in High Speed 2 (HS2)’s Net Zero Carbon Plan by striving to reach a 50% reduction compared…

As part of demolition works for the northern section of the High Speed Two (HS2) Phase One, the Main Works Civils Contractor - Balfour Beatty VINCI (BBV), will handle an…

Environmental noise from the HS2 Railway is the product of the complex interaction of its constituent subsystems (i.e., train, railway systems and civil infrastructure) within the operational parameters of the…

This study has shown that London Clay, that is moderately reactive, can be successfully processed into Calcined London Clay (CLC) to be used as an alternative cementitious material in concrete.…

Railway tunnel ventilation systems present particular problems for predictions of sound emissions, including the relatively high volumetric flow rates, and a lack of well-established models and empirical data. An investigation…

This paper details the approach taken to developing an innovative electric powered piling rig as part of the approach to achieving a diesel-free site on Euston Approaches as part of…

This article explores HS2’s approach for carbon reduction, emphasising their collaborative partnership with Cerclos in implementing Life Cycle Assessment (LCA) methodology, through the eTool software. HS2 and Cerclos have worked…

Community Resource Information Support Platform (CRISP) is a web-based platform which allows the full value of resources to be realised. Sites are able to share surplus goods with one another,…

Existing digital in-transit truck monitoring technology has been utilised in a novel way to directly replace standard concrete compliance testing of fresh properties (i.e. concrete consistence). The adoption and validation…

Lime stabilisation is used to improve the condition and performance of site won materials to enable their use in earthworks fills. Fills with higher dynamic resilience are required for high-speed…

Swell or heave of lime stabilised high sulfate material has been the cause of numerous high profile construction failures in the last 50 years. The formation of ettringite and thaumasite…

The scale of HS2’s environmental assessment is unprecedented. Fundamental to this is understanding the scheme impacts on Traffic and Transport, from local footpath changes to major road and rail improvements.…

For any noise prediction model, it is vital that there is confidence that the forecast noise levels, within the calculated confidence limits, are going to be met in reality. This…

This paper explores the challenges of fragmentation of green infrastructure (GI) and sustainable design solutions to preserve, defragment and strengthen GI. These approaches are explained through a series of HS2…

This paper is based on work to deliver Euston station as part of the High Speed Two (HS2) Phase one works, being delivered by the Euston Integrated Project Team (IPT)…

HS2 uses noise prediction models for assessing the impact of high-speed trains in the surrounding environment and to inform mitigation requirements ([1] and [2]). The HS2 noise prediction model is…

Grendon and Doddershall Meadows Local Wildlife Site (LWS) is located just over 1km west of Quainton in Aylesbury, Buckinghamshire. The LWS citation states that the 24.5 hectare (ha) area was…

Environmental DNA (eDNA) monitoring became an accepted means of surveying for great crested newt (Triturus cristatus) in 2014, following the publication of a DEFRA-funded trial, and it is now used…

To mitigate for the loss of badger setts, closed due to construction of the scheme, over 30 artificial badger setts have been constructed across Phase One under a licence from…

The production of the hybrid Bill for the High Speed Rail (Crewe – Manchester) was a complex, multi-stakeholder and multi-disciplined co-ordination under a challenging programme with risks of a minor…

Learning Legacy has been used on major projects for more than 10 years to capture and share learning from major projects. It was first developed to share the learning from…

This paper presents the design methodology adopted to evaluate the response of a pre-cast reinforced concrete cut-and-cover tunnel subjected to an accidental fire load. The design methodology adopted a simplified…

The challenge for the Phase 2b Environmental Statement was to take 1000s of records of heritage assets across the nearly 300km long scheme and try to standardise them so the…

The Phase 2b Environmental Statement (ES) was one of the largest produced in the UK in recent years. The ES required inputs from a diverse range of organisations across the…

This report describes the implementation of a data-driven approach to report creation for more efficient, standardised outputs. Vast amounts of information are required to plan, manage, and deliver the High…

HS2 Ltd and its delivery partners in the supply chain established the Back to Better Programme to implement consistent and effective control measures for work sites in line with its…

Safety is at the heart of everything the High Speed Two (HS2) programme does. This paper describes the behaviour safety programme that was developed by Balfour Beatty VINCI (BBV) -…

The efficient distribution of construction materials, fully compliant with HS2’s ambition to be carbon neutral and considerate to its neighbours, presented a unique range of materials challenges and it became…
