Crossrail is a railway project being constructed in London, United Kingdom, by Crossrail Ltd – a subsidiary of Transport for London (TfL). The project aims to provide a high-frequency passenger railway service underneath the City of London from east to west, connecting several major underground railway lines.

Building Information Modelling (BIM) is a digital representation of an asset(s) that can be used in infrastructure delivery from planning through to Operation, Management and Maintenance (OMM). SNCF Gares & Connexions (SNCF), a rail station developer, operator and manager in France found that as it developed its stations and services resulting in increased passengers, it required a greater technical understanding of these assets. SNCF Gares & Connexions ( SNCF) looked to BIM as a solution but found that existing BIM solutions did not adequately meet all its requirements.

London relies on a 150-year-old sewer system built for a population less than half its current size. As a result, millions of tonnes of raw sewage overflow the system each year and end up in the River Thames. The GBP4.2 billion (USD5.7 billion) Thames Tideway Tunnel (TTT) is being built to tackle the problem for at least the next 120 years and enable the United Kingdom to meet European environmental standards.

TEAM2100 is delivering the first 10 years of the Thames Estuary Asset Management Programme. The programme covers tidal flood defences as recommended by the 100-year Thames Estuary 2100 (TE2100) plan, which sets out how to manage increasing tidal flood risk from rising sea levels and deteriorating assets to the end of the century.

British Airports Authority (BAA), a major airport operator, constructed Heathrow Terminal 5 (T5), the largest construction project in Europe in the early 2000s. To achieve the desired outcomes to budget, time and quality, BAA decided it needed a model to actively manage the risk on the project. It developed a bespoke relational contract (T5 agreement) for use with its T5 tier 1 suppliers, including architects and engineering design consultants, and general and specialised contractors and manufacturers.

Cross River Rail is a 10.2 km, AUD5.4 billion (2 billion) rail line in Brisbane, Australia linking Dutton Park to Bowen Hills. It includes 5.9 km twin tunnels crossing underneath the Brisbane River and CBD and four new underground stations and eight upgraded stations, doubling the railway capacity across the Brisbane River. It will also involve developing three new Gold Coast stations.

The Gateway Review Process, developed by the United Kingdom Office of Government Commerce (OGC) (a Treasury office) in the early 2000s, is a process now used by several jurisdictions around the world that aims to give greater scrutiny and oversight to major projects throughout their lifecycle.

HS2 is a new high-speed rail line that in Phase One will connect London with Birmingham, and later with Manchester and Leeds. It will serve over 25 stations connecting around 30 million people and will significantly improve travel times between London and the Midlands.

Digital Design-Built Policies are coherent plans for digital infrastructure delivery which align with recognised industry standards and frameworks. They seek to digitise the asset lifecycle by requiring the use of specific digital technologies in the design and construction process.

To service the increased demand and protect Sydney’s inland waterways, Sydney Water commissioned three major inland wastewater treatment plant upgrade projects – Riverstone Wastewater Treatment Plant, Quakers Hill Water Recycling Plant, and St Marys Water Recycling Plant.

Preparations for the London 2012 Olympics involved 137 projects each in separate contracts of varying scale, from major works including the 80,000-seat Olympic stadium, through to preparation works at small-scale competition spaces. The program was delivered amid a local environment of heavy government, media, regulatory, and public scrutiny that demanded the program be delivered on-time with positive health and safety, quality, and environmental and sustainability outcomes .

The Happy Valley Underground Stormwater Storage Scheme (HVUSSS) primarily involves the construction of an underground stormwater storage tank with a capacity of 60,000 m³ located beneath the sports pitches surrounded by the horse racing track of the Happy Valley Racecourse. The storage tank is sized to accommodate a 50-year flood event.

The Town Planning Scheme (TPS) makes land available for urbanisation by pooling and readjusting lands and appropriating areas for public purposes through negotiations between the local planning authority and landowners. Ahmedabad City in Gujarat state, through the Ahmedabad Municipal Corporation (AMC), has undertaken urban expansion using the Danilimda TPS to integrate land use planning and service provision.

Hyderabad's growing population and road congestion resulted in the Government of Andhra Pradesh pursuing Hyderabad Metro Rail which, in its first phase, is a 72 km network covering three high-density traffic corridors.

The Seoul Metropolitan Government (SMG) undertakes infrastructure projects within the city covering assets such as roads, tunnels, and subway lines. Design and planning are performed by departments within SMG while the actual construction work is the responsibility of the Seoul Metropolitan Infrastructure Headquarters (SMIH).

Watercare is owned by Auckland Council and is New Zealand's largest water utility responsible for providing water and wastewater services to the approximately 1.4 million people in the Auckland region. Watercare is required to maintain the network in line with the organisation's ambitious cost, sustainability, reliability, and safety targets.

The New Dunedin Hospital is a new hospital to be constructed in the lower region of New Zealand’s (NZ) South Island. Complex projects such as the New Dunedin Hospital typically suffer from an imbalanced risk allocation between the client and contractor due to a lack of investigative works or market engagement in the planning process.

This case study looks at how Transit Oriented Development (TOD) is undertaken in Tokyo, in one of the most densely populated urban environments, to successfully improve passenger experience and footfall. The Shibuya redevelopment project looks at using TOD to gentrify the local area across the five urban schemes that make up the overall redevelopment: Hikarie Culture Core, Station Central, D?genzaka project, Station-South, and Sakuragaoka project. The project is being completed in stages.
