Reply to comment by volkommm in MTA spent twice as much on Second Ave subway consultants as it did on its construction by NYY657545

Meh, If you can't build three stations worth of escalators with a year's lead time you probably shouldn't be building escalators.

It's not that simple, this is a fairly complicated system. They also have other projects and may not have the ability to scale easily.

Do you know the AMC Lincoln square theater? I was involved in the construction of that place. Ten escalators that I can think of, including, at the time, the longest unsupported escalators in the city. All one company, all installed pretty much at the same time. Contractors did everything else- all the escalator guys had to do was install the escalator into the space provided by the contractor. Despite different lengths and widths, it was all pretty straight forward, and even the free standing unit was off the shelf stuff. I didn't personally work on the escalators, but I remember them showing up in crates and getting assembled pretty damn fast. The four story free standing ones were the only units that took over a week to build.

The guts looked for all the world like giant erector sets. Build the frame to length, choose the right size motor, assemble the links in the stair chain, cut the railing to size. It seemed pretty universal to me, and quite the opposite of bespoke.

I’m not trying to discount your experience at all, but in my experience the general supply chain doesn’t really work the same way it used to. Things that used to be readily available off-the-shelf have a 4 to 26 week lead time now, including specialty fasteners, electronic components, mechanical components for electronics, etc..

Companies are quoting me 6-9 months for small testing equipment, PCBA’s were over a year lead time, etc..

This is more a manufacturing perspective than a construction perspective, but IMO it’s just more difficult/takes longer/more expensive to make things right now.

These stations were built between 2007 and 2016. I don’t think the supply chain issues of the past 3 years were applicable back then.
