The arrangement that's been reported, however, isn't really unusual (at least in my experience when I was still working for a GC/CM. The GC/CM often is forced to take on sub-contractors that they haven't directly chosen and whose draw might not be taken directly from the GC/CM. Two instances that immediately jump to my mind are working for Target, who had preferred subcontractors they mandated and therefore weren't entirely beholden to the GC/CM and when I worked on the basketball arena in Memphis which was funded largely by federal and state money which mandated X% of contracts be locally owned and minority owned businesses which meant basically being told you had to use this HVAC contractor or that Electrician because they were the only ones that ticked the right boxes.
Less than ideal, but it's still the CM's job to effectively coordinate and supervise the job. The story of electrical works being ripped out twice in a fortnight over the same uninstalled HVAC is ridiculous. The electrical contractor should've verified the first time that necessary work had been completed prior to their install, and for goddamn sure the 2nd time.
But it does seem like Tottenham are a nightmare client. If they've really hired their own PM's and taken a heavy-handed role in managing the project in the day-to-day then they've well and truly fucked themselves (and us). You don't tell your surgeon where to cut. AEC is no different, and despite the great disrespect for the industry and the professions involved, the average Joe knows fuck all about how to design and deliver a project of any substance.
I don't know. The article paints a picture of a master clusterfuck - a client who thinks they're a builder, a CM that seems to have let the project get away from them, and subcontractors that can't even marshal themselves. But, it's all taken from an anonymous source which could be fucking anyone with all sorts of motivations to spout off.
On a construction project with a tight timescale its no surprise to me that there will be some mistakes made - from what I see of the construction industry management at most levels isn't as good as many other industries - so one a tight timetable is bound to be more stressful and encourage mistakes if only because scheduling the various sub contractors will be a nightmare. And it will be common for 2 sub contractors trying to work on adjacent or even same areas at the same time due to time constraints, generally considered a recipe for disasters.
But on a prestige project like this its in both Mace and Spurs interests to make this a successful project - If Mace pull this off its a great coup, if its a disaster it will not be good for Mace reputation, so I think Mace will try to manage the project professionally. And ditto the sub contractors - when bidding for further work 'you are only as good as your last contract'.
Assuming NWHL is ready for its first game before Christmas, I think everyone will regard this as a good job by Mace - or at least not a negative. Reason is that the assumption from very early that Spurs would do a deal to get a few away games meaning the first home game would be in September. So a pre-Christmas first game would mean a 2 - 3 month overrun which is not unusual in major construction projects, and therefore Mace will regard it as a decent result (as will its future customers).
