Thames Tideway Tunnel
The Thames Tideway Tunnel will clean up one of London’s greatest natural assets, the iconic River Thames, protect it for generations to come and improve the quality of life for all Londoners. At 25-kilometers long and at its deepest 70-meters below ground, Thames Tideway Tunnel is the largest water infrastructure project ever undertaken in the U.K.
The tunnel, now constructed, runs from east to west London and will modernise the city’s 150-year-old sewer system, originally built for a population less than half its current size, reducing untreated discharges into the River Thames by tens of millions of tons per year. Once complete in 2025, the new super sewer will dramatically reduce sewage pollution, creating a cleaner, healthier River Thames and enabling the capital’s sewer system to continue to serve London for at least the next 100 years.
Jacobs has been the program manager for the Thames Tideway Tunnel since 2008, building on our record of delivering major urban wastewater treatment projects globally. The Thames Tideway Tunnel is the kind of highly complex program that Jacobs enjoys tackling; with multi-site delivery and significant challenges demanding innovation and better ways of working to achieve the best outcomes.
The Elizabeth Line
Over two decades, we’ve supported Crossrail to deliver the Elizabeth line, a complex and significant transport solution in London, U.K., that paves the way for social, environmental and economic opportunities of national significance that will last generations. The program delivery also creates an immense learning legacy that will benefit future major infrastructure development and their communities globally.
Delivered by Crossrail Ltd, the Elizabeth line is the most significant addition to London’s transport network in a generation. It's crucial to a low-carbon transport future, providing greater connectivity and supporting regeneration across the U.K.’s capital city.
One of the biggest railway infrastructure projects in Europe, this fully digitalized, 72-mile (118km) railway line will transform travel both east-west through London, interconnecting with the wider U.K.
Part of the Transport for London network, the Elizabeth line will increase connectivity for millions of people and enable an inclusive society through increased access to jobs and education. New, fully accessible stations transform the public realm, unlocking new development and housing opportunities.
We worked as a strategic partner, in an integrated team with our client Crossrail, overseeing several key contributions on this iconic mega project. Our people have provided over two decades of agile support, from our strategic consultants and economists in the conceptualization stage, to our project teams on the mobilization and delivery phases.
Anglian Water Strategic Pipeline Alliance
Strategic Pipeline Alliance is the biggest drinking water grid program in the U.K. in a generation and one of the largest infrastructure programs in Europe. It relies on diverting water from the wettest areas in the north (Lincolnshire) to the driest areas in the south and the east by building over 310 kilometers (~192 miles) of interconnected pipelines.
SPA’s inaugural scheme first broke ground in June 2021 in Lincolnshire. Once complete, the new network will be longer than the M1 motorway, ensuring more than 600,000 Anglian Water customers receive a safe, reliable water supply for generations. However, this project covers more than just laying pipes: it relies on new ways of working to find the most innovative, affordable and environmentally friendly processes to make this network a reality, and to ensure social and environmental success in all the communities affected.
Dunkettle Interchange Upgrade, Ireland
Major junction reconfiguration in Cork, Ireland to improve capacity, safety and travel times.
Transport Infrastructure Ireland (TII) aimed to significantly improve the existing junction layout for all users, including the junction safety, operation and capacity at this strategically important interface. Located in an intertidal area of conservation with considerable important flora and fauna, all works had to be undertaken while maintaining full operation of the junction and adjacent railway line.
Over 12 years, Jacobs has been TII’s trusted consultant to cover a range of complex challenges on the Dunkettle Interchange project. These have spanned across a range of delivery phases, each with their own unique requirements.
Working in partnership with Cork County Council and Cork City Council to deliver the Dunkettle Interchange Upgrade Scheme, TII’s mission is to deliver transport infrastructure and services, which contribute to the quality of life for the people of Ireland and support the country's economic growth.
Thames Estuary
Thames Estuary Asset Management (TEAM 2100) was set up by England’s Environment Agency to create a long-term approach to managing tidal flood defenses in London and the Thames Estuary, including the iconic Thames Barrier. Jacobs is managing the first 10 years of the program.
Working collaboratively as an integrated delivery team with the Environment Agency and Balfour Beatty, our job is to plan, inspect, refurbish and improve flood defenses along 330-kilometers of the River Thames and reduce the risk of tidal flooding to protect some 1.4 million people, over 4,000 different assets and over $396 billion (£321 billion) worth of property in London, Essex and Kent. This is part of the Thames Estuary 2100 Plan, which will adapt the riversides to rising sea levels over the next 100 years.
TEAM2100 advocates a programmatic approach to managing tidal flood defenses, aspiring to reduce the overall costs by seeking to invest in the right places at the right time. This major program also aims to deliver greater value for public money through innovation, and greater collaboration and joint planning with the supply chain. The program has maintained its ISO55000 asset management accreditation, reflecting an international standard for asset management.
The Scotland 5G Centre
The Scotland 5G Centre is Scotland's national centre for accelerating the deployment and adoption of 5G connectivity across Scotland's Industry and Public Sectors.
Jacobs’ role on the Centre has been multifaceted, delivering technical and business support, from business development and engagement to project management, 5G use case development, and economic impact assessment.
We provide consulting and advisory services, guiding businesses through the benefits and complexities of adopting advanced technology solutions enabled by connectivity. Our focus on data solutions resonates with the essence of 5G which is transmitting larger amounts of data with improved latency and resilience.
This allows businesses to adopt a data driven approach to their operations. This commitment to a data-driven approach ties in with our climate response - by enabling data-driven operation, businesses can optimize their use of resources to significantly reduce their carbon footprint.
We’ve worked with businesses in a diverse range of sectors including transportation, energy, health & social care, aquaculture, education and whisky production, to discover the untapped potential that embracing 5G technology holds for them.
Scotland’s 5G journey isn’t just about technology; it’s about shaping a better future for all.
Lower Thames Crossing: Improving connections and economic growth opportunities
The Lower Thames Crossing, England’s single biggest roads investment project since the M25 was completed more than 30 years ago, is unprecedented in size and scale. The longest road tunnel in the U.K. and one of the largest diameter bored tunnels in the world, will give the opportunity to transform journeys across the south-east and beyond.
Driving economic growth
The Lower Thames Crossing will form a vital part of the U.K.'s transport infrastructure, and the areas it will serve are home to economic hubs, key U.K. ports and thriving communities. It will help businesses large and small to grow and bring people and communities closer to jobs, education and leisure opportunities.
The new road will almost double road capacity across the River Thames, east of London. The 70mph crossing and the new connecting road network will provide, quicker, safer and more reliable journeys locally, regionally and nationally.
Sidmouth Amphitheater: Flood defenses with a theatrical twist
A new flood alleviation scheme to protect residents and properties in Sidmouth, U.K. from future flooding doubles up as an amphitheater for the local community.
For many years Sidmouth, a town on the southwest coast of England, has suffered regular stormwater flooding, with overland flowpaths draining to a low point directly in the town center, putting up to around 150 residential properties and businesses at risk. If a rare, major storm were to take place many local residential and commercial properties would be at risk of flooding.
Devon County Council brought Jacobs in to develop a flood management scheme that would overcome this and navigate the town’s drainage challenges including a dense town center, narrow streets and historic buildings with shallow foundations.
But the team went further and were inspired to turn the flood defenses into an amphitheater, providing a public space for local communities to visit. They also reinstated a wildflower meadow and planted 11 new trees. Now over 300 people at any one time can enjoy local events in a unique natural setting, so long as the weather stays dry!
Fast-Tracking Social Value with the Transpennine Route Upgrade
The Transpennine Route Upgrade (TRU) is a large-scale railway infrastructure investment program between Manchester to York via Huddersfield and Leeds.
It will deliver faster, greener and more reliable journeys across the north of England, and it places people first in a pioneering community-needs approach that uses key social assessments throughout the program lifecycle to shape design and delivery for the greatest impact.
TRU will achieve far more than improving railway assets — it will enhance lives in a legacy of moving more essential goods by rail, attracting more people to use the train, helping communities prosper, creating jobs for local people and applying decarbonization principles.
TRU is being delivered by more than nine organizations — including Jacobs — and is united in a common mission to deliver the greatest value to communities along the route. Between April 2019 and March 2024, the TRU social impact program had already generated $1.86 billion (£1.47B) in social value by delivering 264 apprenticeships, engaging more than 42,460 young people in STEAM (Science Technology, Engineering, Arts, Mathematics) delivery of 16,300+ days of work experience, contributing 11,000+ hours of volunteering, and $532 million (£420M) spent with local businesses and $277M (£219M) with Small Medium Enterprises (SMEs).
