I'm not in road construction, but am in "building" construction. As Loud and Proud put it, they can't find enough people to run all of them 24 hours/linear schedules, you overwork your crews they burnout and at the end of the construction season you're left with noone doesn't help either. Not to mention they have to wait for subcontractors (the only control they have over their schedule is money) and outside contractors such as utility contractors who may not even be under their contract; have to finish their portion of the job first, who also are fighting the lack of workers. Construction is a finicky thing. One project can go smooth start to finish, and the next project can go hell in a handbasket in a week because everything is dependent upon schedule you end up being 2 days late (heck I've had even a day late screw me over before) finishing something can put you back a week or more because the next guy down the line had a schedule to meet and workers to put to work so they put them on another job. They can't play hopscotch with their workers as that is very inefficient so a lot of times it ends up whichever one is ready for them first is the site they go to. Then throw material shortages (which I didn't know about until Tu-Uyen Tran - who seems to be a heck of a reporter by the way how did he ever end up at the Herald for a few years??) you're looking at a lot of variables that can skew your schedule badly no matter how good of planning you do. Master is being made a bit of a scapegoat because they're on one of the highest profile jobs on a business centric street. Only other one would be 25th street overpass project (that I can think of right now..). Obviously it can be done, such as ABC's extreme makeover shows indicate... but all of those contractors sign on knowing that their people/materials needs to be there at x time and they use local companies so the companies sacrifice for a week or so to get the "free publicity". There is no way a general contractor or anyone could do that month in and month out for 6+ months of the year or more. And these houses are planned out well advance, around 5-6 months(?) I knew about the minot one way before it was announced and the sales guy/management that sold the lumber knew about it before I did. $500,000 Houses are a bit less "complex" in ways than a road construction project.
Let me ask all of you if you ever had a small project at home that you were building something. Did you think in your head well it's going to take me X hours/days/weeks/months to do this? How often were you right on the money and how many times do you go over/under that? Guessing most of us underestimate the time we think it will take us... Then perhaps you ran out of screws, you ran to the local Home Depot and got more right (which you need to look at as a delay in your schedule but its only affecting you and junior who's anxious to get on that swingset/treehouse you're building), well what if Home Depot/Lowes/Menards/Mac's said sorry don't have any! Now multiply that out about 100 times dealing with subs and utilities and you got yourself a regular old construction project and many times they don't have as many options to get the "screws" as we do for our little home projects because they're REQUIRED to follow the specs which can get right down mundane at times to the stupidest things especially in public projects.
