Generally bid that is not "technically complete" .i.e. does not demonstrate a real ability to undertake and complete the project can be rejected. There is some engineering discreti…

Most large infrastructure projects have a large number of trades for a short amount of time Contractors have people,experience and equipment that would be cost prohibitive to maint…

The block chain has fundamentally reinvented the way startups fleece investors.

There is a non-zero chance that May is replaced by a hard brexiter and they insist, by will of the referendum, that a hard brexit must occur. You can see UKIP bubbling back up in f…

I don't know if this is helpful to you, but Walmart pharmacies have inexpensive insulin if you ask for it.

As a random piece of trivia, in cab signaling was pioneered in the 1920's and implemented commercially by Pennsylvania Railroad the 1930's while upgrading their main line between N…

Okay, my bachelors was in civil engineering and I have worked in construction and engineering for just over two years now. Most public projects today have generous structured incen…

There is also the possibility that a poorly engineered or rushed tunnel could destablize the foundations of structures above.

To clarify, I was talking about traditional subway construction and why changes in boring costs would not change that.

A boring machine that could dig 10x as quickly (and hold all other desirable characteristics equal) would save tens of billion of dollars in infrastructure projects around the worl…

If the Boring company could produce a reliable boring machine that dug at 10x speed, the boring machine would far far more valuable than these tunnels. It makes me think that the c…

If you have the kind of nice geotechnical conditions that permit the use of tunnel boring machines then tunneling isn't actually very expensive. What's killer is the cost of subway…

If your goal was to cut costs and your largest single expense was boring, you would choose two 14' bores over a single 28' bore, because a 28' bore has a cross section twice as lar…

Building underground interchanges that include complete grade separation would entail building cloverleaf interchanges underground. Cloverleaf interchanges usually cost somewhere f…

I don't think Musk's goal is to destroy public transit, but things like the hyperloop have been used as a bludgeon to attack high speed rail initiatives. [1] ( https://www.investor…

Ahh, I appreciate the correction! I thought they were going to have a single track tunnel with passing sidings based on the 1.6 billion dollar construction costs, which would limit…

I feel like this this project will eventually morph into an undersized subway.

The article claims service every 15 minutes during most of the day, which means it will be extremely unprofitable to build. This isn't meant to return it's investment, it's meant a…

Bitcoin could go the way of any number of other cyptos; back to zero. In any case, nobody uses Bitcoin as a currency because it's logistically harder for 99.9% of people, and nobod…

Seem to work pretty okay in the rest of the developed world.

The words of leaders should always be taken literally, because the those words only become "jokes" when they are otherwise unexplainable in rational discussion.

Right, there is a real and serious problem with public infrastructure costs massively ballooning, worse than any other developed country. But on the other hand, if you don't build …

Its possible to achieve substantially higher speeds, but that would require grade separation and electrification, which are much too expensive for a private company to take on.

Transit isn't really intended to solve traffic problems, transit is basically a work around to allow cities to scale in spite of traffic.
