I'm neither confirming or denying this is the issue, but if the existing mains was 63mm it would have cost a lot to replace it, also the old mains was delivering most of the water to ground level and 1st story, now it needs to go up considerably higher requiring a greater pressure, 90mm will allow 70% more pressure than 63mm.
My expertise is more of the electrical side of things and I believe that issue was a much simpler and cheaper fix as the capacity of the site is similar to what it was prior to the upgrades, the LED floodlights use around 50% less power than the old discharge ones (and deliver around 30% more lumens), which means that capacity was available for the main stand.

Sounds like we would have been better off employing you to project manage it, FT ??
Is it possible to switch things round and do as you suggest, or does the structural design prevent that from happening ??

What's very disappointing for Matt and the club is that the new era has started off the field in such a way .

The new stand isn't just a new stand it's much more than that , it's a significant move forward and the first project that will hopefully take the club to where we all believe it can compete along with many other projects to come .

Whilst I wouldn't go as far as to say we've fallen at the first fence it's still none the less unacceptable .

As others have said Matt must be fuming , the man comes across as someone who insists on the highest of standards and in my opinion is the real deal , he's not bought the club to scratch around just above the bottom of Super League .

Hopefully it gets sorted relatively quickly .

I'm pretty sure he knew he wasn't buying a finished product.
He'll get these things sorted I'm sure.

To a certain extent this is the advantage of being in Championship this year.
We can resolve them slightly under the radar so we can be up and running in Super League
