The Colne Valley Viaduct, a 3.4km structure, will be the longest railway viaduct in the UK and has been designed to meet demanding technical, environmental and operational requirements. A key...
The Chiltern Tunnel will be the longest tunnel on Phase One of High Speed Two (HS2). As part of the safety systems it is necessary to be able to provide...
This paper describes the design development of the deepest ventilation shaft along the C1 alignment - Chalfont St Peter Ventilation Shaft. The developed design solution was a 17.8m internal diameter,...
Building Information Modelling (BIM) has been adopted for the design and build of the 16km Chiltern TBM Tunnel as part of the High Speed Two (HS2) project. A complete set...
The operation of jet fans to ventilate tunnels generates sound that propagates within the tunnels, and can be emitted to external locations, which may include noise-sensitive receptors. To achieve suitable...
High Speed Two (HS2) intersects utility company networks throughout its length. Utility works are an important factor when planning and carrying out infrastructure projects, and similar diversionary works are likely...
HS2 has set strategic goals in health and safety to create a railway designed, built and operated to world class standards creating a legacy of new and better standards in...
The route of the UK’s High Speed Rail network traverses the hilly terrain of the south midlands of England on a low, flat, straight alignment. Creating this alignment requires the...
The design of the roof at Interchange station embodies the HS2 Design Vision. It is both a conceptual response to its site’s rural context and a demonstration of how integrated...
Protected species constraints are an early consideration for nearly every development project, and where impacts cannot be avoided mitigation licensing is a legal requirement. HS2 Ltd are the licensee for...
The High Speed Two (HS2) Sustainability Policy sets out the programme’s ambition to build the most sustainable high-speed railway of its kind in the world. The Phase One stations are...
High Speed two (HS2) believes that an inclusive design approach will make the network easier for everyone to use. The design of stations and rolling stock will be based around...
The design of the civil engineering works in High Speed Two (HS2) is a good example of what can be achieved when the Building Information Modelling (BIM) process is embraced....
Streethay Cutting is a 2.5km long cutting that lies approximately 1km to the east of Lichfield, Staffordshire. It is at the northern part of HS2 Phase One, beyond which the...
Ground conditions present one of the major areas of uncertainty and risk for High Speed Two (HS2) Phase One and have a significant impact on project affordability. The ability to...
Engineering geologists and geotechnical engineers need the right tools to efficiently investigate, analyse, model and share their geological understanding of expected ground conditions with the wider project team as and...
The High Speed Two (HS2) Phase One route passes through a diverse and continuously changing British landscape. Structures along the route should be designed and constructed to respond to this...
