Tutor Perini JV's $1.18bn Manhattan Tunnel Contract
Summary
A joint venture between Tutor Perini and its subsidiary Frontier-Kemper Constructors has been awarded a $1.18 billion contract to construct the Manhattan Tunnel, a key preparatory component for the larger $16 billion Hudson Tunnel Project (HTP).
Key Project Details
- Scope: The JV will design and build 700 feet of twin, 30-foot-diameter tunnels from the Manhattan Bulkhead on the Hudson River to the Hudson Yards Concrete Casing.
- Purpose: This temporary tunnel shell will clear the way for tunnel boring machines (TBMs) to later excavate the permanent tunnel.
- Challenges: Construction will navigate major sewer lines, utilities, and underground obstructions, including archaeological finds, debris, and remnants of the collapsed 1973 West Side Highway.
- Technology: A protective digging shield will be used to keep most of the work underground.
- Timeline: Work begins in spring 2025, with substantial completion by 2029.
Hudson Tunnel Project (HTP) Overview
- Purpose: HTP will add a new twin-tube rail tunnel under the Hudson River from Secaucus Junction, NJ, to Penn Station, NY, and rehabilitate the existing 115-year-old North River Tunnel.
- Current Rail Bottleneck: The only rail tunnel under the Hudson carries 24 trains per hour but suffered extensive damage from Hurricane Sandy in 2012, requiring heavy maintenance.
- Economic Impact: The Northeast Corridor, from Washington, DC, to Boston, contributes 20% of the U.S. GDP, making this project critical to national infrastructure.
- Completion Timeline:
- New twin-tube tunnel: Opens in 2035
- Rehabilitated North River Tunnel: Opens in 2038
Additional Contracts
- In August 2024, a joint venture of Lane Construction, Schiavone, and Dragados won a $466 million contract to build the New Jersey-side section of the tunnel.
The Gateway Development Commission calls HTP "the most urgent infrastructure program in America."

Quotes for February 6
Good morning, everyone! Well, good morning for me—it might be the middle of the night for some of you.
Today is February 6, 2025. It’s been a crazy week at work, and I haven’t been getting much sleep, but I’m hoping that changes soon.
This morning, I came across a bunch of quotes on my Reedwise feed. Since I forgot to check it yesterday (blame the hectic week!), I now have two days’ worth of quotes to share. I should probably write something more thoughtful today, but honestly, the lack of sleep isn’t helping my creativity.
Hope you’re all doing well!Quotes
"AI is also useful; ask ChatGPT how someone with an opposing viewpoint might receive your message."

"Let’s dispel the myth that negative self-talk is somehow more honest than positive self-talk. Positive self-talk is more realistic. Negative self-talk exaggerates the impact of what occurred."
— Devora Zack, Networking for People Who Hate Networking
"Digital Minimalism A philosophy of technology use in which you focus your online time on a small number of carefully selected and optimized activities that strongly support things you value, and then happily miss out on everything else."
— Cal Newport, Digital Minimalism
"Social Dominance Theory (SDT) begins with the basic observation that all human societies tend to be structured as systems of group-based social hierarchies."
— Jim Sidanius and Felicia Pratto, Social Dominance
"Fungi produce around fifty megatons of spores each year—equivalent to the weight of five hundred thousand blue whales—making them the largest source of living particles in the air. Spores are found in clouds and influence the weather by triggering the formation of the water droplets that form rain and the ice crystals that form snow, sleet, and hail."

"To be a good listener is to accept pauses and silences because filling them too soon, much less preemptively, prevents the speaker from communicating what they are perhaps struggling to say. It quashes elaboration and prevents real issues from coming to the surface."
— Kate Murphy, You're Not Listening
"Where there is energy and enthusiasm (which comes from believing in the action that is taken) ownership will be generated and this in turn will ensure that activities are sustainable. Ideas and innovations only take off when there is a high level of ownership which is transmitted through networks – in the same way that a virus spreads through a population. Enthusiasm is built from a belief that something is important, and will actually make a difference; energy and momentum channelled through relationships."
— Danny Burns and Stuart Worsley, Navigating Complexity in International Development
"The second thing you must consider is whether people base their decisions on emotion or logic. The true answer to that question is, in fact, both; it is just that the decision is always made for emotive reasons first."

Dancing with Systems: Navigating Complexity for Transformative Change
Systems Quotes
"Delays are pervasive in systems, and they are strong determinants of behavior. Changing the length of a delay may (or may not, depending on the type of delay and the relative lengths of other delays) make a large change in the behavior of a system."
–Donella H. Meadows, Thinking in Systems
"Such challenges are often inhibited by individual and organizational ‘defensive routines’, firmly entrenched in minds, setting cognitive and social limits on learning."
–Ben Ramalingam, Aid on the Edge of Chaos
"Defensive routines" is an important concept when it comes to understanding how learning can be inhibited, both individually and organizationally. These routines, as Ben Ramalingam describes in Aid on the Edge of Chaos, are deeply ingrained patterns of thinking and behavior that create cognitive and social barriers to learning.
This idea also reminds me of something I recently came across about organizations exhibiting an "immune response" to resist change efforts. It seems closely related, as both highlight the instinctive resistance to disruption or transformation within systems.
"to date there is a lack of studies that bridge the divide between small case-based interventions and global systems at broader scales, and the complex interactions across scales and processes. This paper works with a leverage points framework to consider systems transformation. It focuses on four individual sustainability interventions in the textile sector and explores how they are embedded within a complex set of nested systems, and how these connected systems shape the transformative potential of the interventions."

"Understanding processes of systems change therefore requires us to ‘dance with systems’ (Meadows 2001), meaning to learn from and engage with systems through dynamic, rather than static, perspectives, with passion and vision, to understand their functions or purposes and connections, and see how our values and the system properties may interact (Meadows 2011; Constable et al. 2019)."

"Up-side" Risk & Development
Brainstorm on "up-side risks" and development economics
"The only ignorant question is the one not asked"
Disclaimer
As (I hope will not be too) apparent to anyone with a some level of economics or statistical education, this is not my primary area of work - yet to open the bridges between siloed disciplines (aka interdisciplinary work) we must start walking into personally murky waters. We must not fear retribution for basics not received or lost (can you tell this is a pep talk?)
Up-side Risk
Are there "up-side" risks? In other words, how does one assess (or does one assess) the risks associated with a "positive" upside event? Of course for those that hedge there is upside risk. Hmm. So perhaps we can see investment in things like Air Conditioning or perhaps water systems and electrical systems as a hedge against risks in natural capital? Of course in an urban environment - with population densities well beyond the carrying capacity - such systems are no longer a "hedge", no longer "insurance" but full blown... cost? I now reach too far beyond my ken. Perhaps some input from others on how to think this through.
