Ground work such as what you describe probably wouldn't have as much of an impact. The NHHS effectively had a "head start" because there was no need for the creation of a new right of way.
In some cases, due to right-of-way width limitations, some of their construction was on both sides of the existing track. I'm reasonably sure there were times cranes lifting bridge pillar materials and the like sometimes blocked that track area. As far as cutting in new switches, signals, etc goes, I saw multiple switches, perhaps 100 yards of track, and a completely new signal bridge installed in West Springfield in 4-5 days about 5 years ago when there was a derailment on the approach to the CT River bridge. I recall they had the first track open in less than 24 hours. A lot can be done in a short amount of time with the proper motivation!

The stretch I went through today was at least 10 miles long, maybe even 15 miles. I didn't time it, but I think we spent a good 20 minutes at restricted speed going through the construction zone. The construction zone on the Ronkonkoma line on Long Island that I went through 6-7 months ago was perhaps 10 miles long as well.
Given the slow construction progress on highway repairs in the Springfield area the past 20 years+ since I moved there from Wisconsin, I guess I shouldn't expect that government run construction projects will be done as quickly and efficiently as I'm accustomed to seeing. But then, those contracts have very lucrative incentive payments for early completion (they even worked 3 shifts/day!) as well as very expensive penalties for late completion. Out here, it seems that delay after delay occurs. My favorite one was several years ago when a single steel beam for the South End Bridge project in Springfield was too short/long/whatever. That caused a 6 month delay and ALL work on the bridge stopped! Obviously, Easterners are more complacent about slow construction times than their counterparts elsewhere.
It'll be interesting to watch "how it's done" at NYP "New York Style". I have little doubt the current schedule for emergency track repairs will drag on for some time.
