Catskill-Delaware Interconnection

Connecting two aqueducts to preserve the quality of New York City water

Together, the Catskill and Delaware Aqueducts deliver more than a billion gallons (3.8 billion liters) per day of drinking water to New York City from six reservoirs located in the Catskill Mountains. Constructed from 1907 to 1916, the Catskill Aqueduct runs 92 miles (148 kilometers) from the Ashokan Reservoir in Ulster County to the Hillview Reservoir in Yonkers. An at-grade, gravity-flow conduit, it crosses 1,100 feet (335 meters) below the bed of the Hudson River at Storm King Mountain. In 1909, Harper’s Monthly said, “The project ranks as the greatest municipal water-supply enterprise ever undertaken, and as an engineering work is probably second only to the Panama Canal.” It carries about 40% of New York City’s water supply.

Hydropower provides Nevada with 1 GW of on-demand electricity

The 1GW White Pine pumped-hydro storage project is under development in White Pine County, Nevada. Infrastructure includes two reservoirs on the Duck Creek Range and Steptoe Valley, underground tunnels, shafts and caverns, and a new 25 mile (40km), 345kv transmission line. The underground powerhouse will contain three variable-speed pump turbines and the project will provide network frequency regulation, generating and pumping operating flexibility, and rapid response to power fluctuations.

Following a pre-feasibility study, we were appointed Owner’s engineer to deliver a detailed feasibility study that includes scrutinising the already developed concepts, collecting additional data, evaluating technical viability, and advancing the engineering of the project. We are also supporting rPlus to secure a licence for the project from the Federal Energy Regulatory Commission (FERC).

Pending engineering and environmental approvals and the completion of the FERC licensing process, construction is expected to begin in 2025. Construction will take between five and seven years. White Pine PHS will provide 8000MWh of energy storage to generate up to eight hours of electricity and provide direct employment and secondary jobs to improve the White Pine County economy, helping Nevada meet its goals for a carbon-free energy future.

Solution

Reesha Tech was retained as part of a joint venture team to perform the geotechnical investigations and the structural, architectural, and landscape designs for Catskill-Delaware Interconnection. We also provided program management services for the overall joint venture contract, and technical reviews of the entire interconnection design.

The Interconnection includes a major underground structure, designed as an expansion of the existing Delaware Aqueduct Shaft 4. The new structure features large-diameter piping, flow metering, and pressure-reducing valves.

The Interconnection can transfer up to 365 million gallons (1,382 million liters) of water per day from the Delaware Aqueduct, reducing its pressure from as much as 100 pounds per square inch to open-channel flow conditions.

Building Information Modeling (BIM) and physical scale models were used to optimize the hydraulic design of the Interconnection. Our design allowed for construction with minimal outages for the existing aqueducts.

Outcome

The Catskill-Delaware Interconnection will allow the NYCDEP to reduce the use of Catskill water supplies during periods of high turbidity. This will reduce the need for chemical water treatment while maintaining high-quality water without filtration.

In May 2013, Department of Environmental Protection Commissioner Carter Strickland said, “Ensuring the delivery of more than 1 billion gallons of high-quality water to more than 9 million New Yorkers every day requires long-term planning, and the interconnect at Shaft 4 is an important project for the future of New York City’s water supply system.

“By connecting the Delaware Aqueduct to the Catskill Aqueduct, DEP will have another mechanism to help it deliver the highest quality drinking water from across its supply system.”

As part of planned testing, the NYCDEP decided to temporarily shut down and partially dewater the Delaware Aqueduct for three weeks, starting in October 2023. The aqueduct would be shut down again from October 2024 until the spring of 2025 to repair leaks.

PROJECT: LINKING UP SILICON VALLEY

The San Francisco Bay Area is one of the most populous regions of the US, home to 7.7 million people. From 1940 to 1970, the population surged from 1.7 million to 3.6 million, leading several Bay Area counties to join in the 1960s to form the Bay Area Rapid Transit (BART) system.

BART is now the fifth-busiest heavy rail rapid transit system in the US, with 130 miles (210 km) of track serving an average of 118 million passenger journeys each year.

Santa Clara County originally chose not to join the transit system. This gap in the rail network around the Bay forces many commuters to travel by car.

Two projects for the Santa Clara Valley Transportation Authority (VTA) are closing the gap and transforming transportation for millions of workers at the heart of the US tech industry.

The BART Silicon Valley Extension will give more choice to travelers. It is expected to accelerate a 20-year-long rise in the number of trips made by public transportation. Together, Phases I and II will provide access to transit for 1.7 million residents of Santa Clara County, with capacity for 54,600 passengers per day, helping relieve heavy congestion on two north-south commuter highway routes

It’s more than a transit project — BART Silicon Valley is an entire program of improvements that will transform Silicon Valley.

We managed Phase I in joint venture with Bechtel. On Phase II, we led the preliminary design and continue with advanced design in a joint venture with San Francisco-based PGH Wong Engineering.

“It’s more than a transit project — BART Silicon Valley is an entire program of improvements that will transform Silicon Valley,” says Michael Lehnen, our BART project manager.

A two-phase extension

Phase I extended the BART service 10 miles (16 km) from Alameda County into Santa Clara County, with stops at Milpitas and Berryessa/North San José. The project broke ground in 2012 and opened for passenger service on June 13, 2020.

Michael explains that the project has brought wider benefits including transit-oriented communities, multimodal transportation connectivity, plus roadway, utility, and environmental improvements.

Phase II

6 miles of line
5-mile tunnel
3 underground stations

Phase II will add an extra 6 miles (10 km) to the route. Of this, 5 miles (8 km) of the alignment will consist of a large single-bore tunnel. It will include three new underground stations in San José and terminate at an aboveground station in Santa Clara, with connections to Caltrain Commuter Rail, Amtrak, VTA’s light rail, and the future California High-Speed Rail route.

At an estimated cost of $9.3 billion, Phase II is the largest transportation project in the history of Santa Clara County. Construction began in spring 2024 and is estimated to be completed by 2036.

Station innovations

Underground transit systems in urban environments are traditionally built using twin-bore running tunnels (train guideways), with cut-and-cover methods used for the stations.

However, the new stations for BART Silicon Valley Phase II are in some of the busiest parts of San José. Cut-and-cover construction would mean months of disruption in the bustling commercial center, as sites are cleared for excavation, roads are closed, utilities are relocated, and traffic is diverted.

San José is a key commercial center, home to globally important companies including Adobe and Google, which plans to add almost 800,000 square yards (700,000 square meters) of office space and 4,000 new housing units. Popular hockey and football teams also bring large crowds to downtown San José and Santa Clara, which in turn brings revenue to local restaurants and hotels.

The challenge was to come up with the best alternative to cut-and-cover construction that would have caused major disruption.

“Our work includes a tunnel 5 miles (8 km) long, to be constructed by a tunnel boring machine (TBM). There will be 1 mile (1.6 km) of street-level track, three underground stations, an aboveground station and a train yard, and a maintenance facility near the end of the extension,” says Michael.4

Underground options

Over the course of almost 20 years, designs for three tunnel configurations had been developed to varying degrees of completion:

Twin-bore tunnels and cut-and-cover stations
Single-bore tunnel 43 feet (13 meters) in diameter with tracks in stacked and side-by-side configurations, and stacked station platforms
Single-bore tunnel 50 feet (15.2 meters) in diameter with tracks side-by-side and with center island station platforms

The single-bore solution enables stations to be built avoiding the aboveground disruption of cut-and-cover in the public right-of-way.

But using a single-bore tunnel for both guideways and at underground stations has only been done once before, on Barcelona Line 9 in Spain. That is a comparatively small transit system, with fewer than 750 passengers per train. This project is for heavy rail, with larger trains carrying more than 2,000 passengers.

Michael outlines our involvement: “We began in 2019 by examining the concept designs to assure VTA that a single-bore tunnel was possible,” he says. “The smaller, 43-foot (13.1-meter) option, would have been less expensive to build than the larger bore option from a pure tunneling perspective, but the changing internal configuration, from side-by-side guideways switching to stacked stations, brought complexity.”

48 feet wide
5 miles long

Kiewit Shea Traylor — a joint venture of Kiewit Infrastructure West, JF Shea Construction, and Traylor Brothers — is a progressive design-build contractor for the tunnel and trackwork components of the BART Silicon Valley Phase II project.

Kiewit Shea Traylor proposed a larger 48-foot (14.6-meter) tunnel and side-by-side track configuration throughout the tunnel and stations, making it the third-biggest bored tunnel in the world.

Although the larger diameter increases the cost of tunneling, it reduces risks and standardizes operations associated with tunnel construction, improving the probability that the project will be delivered to cost and schedule.

The right engineering solutions

Turning the large-diameter tunnel concept into an efficient engineering solution has involved a range of expertise. This includes the following:

Geotechnical investigation and reporting including preparation of a geotechnical baseline report, with a detailed characterization of ground conditions used as a reference point for detailed design of the tunnel, procurement, and development of the contractors’ construction strategy. Geotechnical investigation showed that the site mostly consists of soft ground with a high-water table. The tunnel boring machine will need to be specified to cope with these conditions.
Preliminary design of the large-diameter single-bore tunnel including interdisciplinary building information modeling (BIM) to establish the internal diameter of the single-bore tunnel, precast concrete lining, adit (horizontal passageways) configuration, tunnel portals, and internal structures. Preliminary design has considered the trains’ range of motion and the spatial requirements for ventilation/smoke extraction, access and emergency egress, power supply, utilities, and roadside facilities.
Preliminary design of the four stations including deep shafts and mined adits to connect the station headhouses to the tunnel. At the Downtown San José and Diridon stations, the primary construction activities will be off the street, allowing traffic to continue and limiting disruption to businesses and the traveling public.
Track and systems development including preliminary design of direct fixation trackwork and crossovers.
Ventilation system analysis and design based on the large-diameter single-bore tunnel and unique station configurations. Computational fluid dynamics (CFD) analysis demonstrated that the system will be able to handle smoke and fire design requirements effectively, keeping passengers safe and aiding emergency responders. Coupling CFD with our custom-made STEPS software, we modeled passenger egress to demonstrate that our design meets or exceeds emergency evacuation requirements.
Development of a digital delivery system. The digital delivery system complies with ISO 19650, the international standard for digital delivery, and uses the latest technologies for efficient production and collaboration between our team, our client VTA, the progressive design-build contractor, and 40 subconsultants. BIM enhanced multidisciplinary coordination during preliminary engineering and will continue to do so going into advanced design. The unified digital model of the project will be handed on to the VTA as an asset management tool for future operation and maintenance of the extension.

BART Silicon Valley Phase II is expected to open in the early to mid-2030s. The extension will bring economic vitality through community connections to thousands of jobs around the bay, mixed-use development around the route, and cleaner air through a reduction in road traffic.

Maximising the benefits of artificial intelligence for infrastructure calls for strong governance to minimize the risks

Ensuring AI is used responsibly is critical to safety and security

The announcement earlier this year of the UK government’s AI Opportunities Action Plan means more organizations than ever before are looking to artificial intelligence (AI) to unlock improved productivity. The plan estimates that – if AI is fully embraced – the gains could be worth up to an average of £47bn to the UK each year over a decade. Mott MacDonald’s digital project principal in UK and Europe, John Farrow, considers how the infrastructure industry can deliver this potential without compromising on safety and security.

Our experience of working with major government clients to implement AI means we know that realizing this figure securely and responsibly is not going to be straightforward, but it is not unrealistic – we have seen the benefits firsthand. Recent deployment of AI on one part of a major infrastructure project to track drawings and use of design codes has potential to deliver a cost saving of £0.5M in work hours. On a multimillion-pound scheme this may sound like a drop in the ocean but if AI could be rolled out to improve efficiency in the same way on other parts of the project, the value grows.

Launch of the government’s AI plan creates an urgency to develop, procure, deploy and adopt AI technology and capabilities. Nonetheless, like any new technology, there are risks that need to be addressed but, with AI, if the right understanding is not in place, the risks could be greater than with other digital solutions. These challenges make the need for human oversight and robust governance around AI adoption paramount.

AI risks

The potential for biased algorithms, privacy and data protection concerns and the ethical implications of algorithmic and autonomous decision-making are significant hurdles. AI might take actions that are not easily understood or anticipated by human operators, plus AI systems might expand the attack surface for cyber threats. Malicious actors might target AI systems directly or use AI to enhance their attacks on critical infrastructure.

Overreliance on AI decision support tools could lead to mistakes and operational inefficiencies, potentially leading to the failure of assets. Without proper governance, the risks associated with AI could outweigh its benefits, leading to public distrust and regulatory action.

Ground truthing to evaluate the responses given from AI and using synthetic test queries to manually check how the AI is working is essential. This has been underlined on work we have proposed for a major government contract where developing the business case requires ensuring compliance with 8,000 documents. That would be almost impossible with manual techniques but by using a retrieval augmented generation database and searching using large language model AI, the time involved can be significantly reduced. However, checking and evaluation is still important to ensure confidence in the output and understand how to improve accuracy and reliability.

Why governance matters

AI governance refers to the frameworks, policies and practices that ensure AI systems are developed and deployed responsibly. Ethics in AI deployment goes beyond compliance with regulations – it involves a commitment to doing what is right, even when not mandated by law.

As an example of the challenges we help address, we recently collaborated with a major government client to develop a safe and ethical AI-based analysis. This solution ensured that confidential information remained protected while creating a comprehensive data dashboard. The quantity and type of data meant that manual techniques would be too labor intensive, but the nature of the data led to questions over whether the processing could be done safely with AI. The technical solution may have only taken a few days to create, but before reaching that stage it was important for the teams to consider what could go wrong with using AI and the impact of any failure.

To overcome the legal, security and ethical challenges, we bring together subject matter experts with technical experts in AI to advise clients on the risk, while also challenging, testing and checking the solution to ensure the AI is acting as intended.

However, the ethical issues need to be considered more broadly than on a project-by-project basis. When organizations integrate AI governance and ethics into the core of their operations, they not only safeguard against potential pitfalls but also demonstrate leadership in the responsible adoption of emerging technologies. While the government’s AI plan presents the potential for the technology to support its growth agenda, there is also an emphasis on responsible adoption too and that level of AI maturity takes time to develop within organizations.

Six steps for responsible AI use

Organizations that want to use AI responsibly should:

Tailor AI governance to organizational principles and risk appetite – articulate acceptable uses of AI and measures for addressing potential ethical issues, while building a coherent narrative around the approach to AI that aligns with the values of the organization.
Have leadership support and organization-wide buy-in – commitment from leadership is required at the earliest opportunity to promote best practices and influence cultural change within the organization.
Start slowly and build out – leverage existing governance structures and processes to build an AI assessment and use external support until AI maturity is reached to minimize the risks.
Incorporate diverse voices – involve customers, communities and other stakeholders in discussions about how AI is used on projects to build trust in the use of the technology.
Promote AI literacy – ensure all employees have the right skills, confidence, capabilities and tools they need to embrace the responsible adoption of AI but also understand the limits of their knowledge, as well as the capabilities of the technology.
Monitor regulatory developments – stay informed about evolving AI regulations and adjust policy and practices as necessary.

Understand your risk

As AI continues to shape and reshape industries, the importance of fit-for-purpose governance and ethical decision-making cannot be overstated. Each AI use case comes with its own ethical dilemmas and governance concerns. . From perpetuating biases to introducing new security vulnerabilities, organizations that push forward without understanding and mitigating these risk consequences will face challenges ahead. Irresponsible AI applications and practices not only increase risk to an organization and its people but can also negatively impact the communities they serve and society at large.

Embracing responsible AI is not just about staying competitive – it’s about leading with integrity and foresight, enabling navigation of the AI landscape with confidence. Starting the journey now will prepare organizations for the coming future where AI is integral to all aspects of infrastructure development and management. The first step in the journey is likely to be an assessment of AI skills across your organization and supply-chain.
