Is it just a coincidence?, page-18

You will not see many other trades onsite when a machine of that caliber is in use, the dangers of being hit by the boom being auto operation will require an exclusion zone.
the advantage of it only taking a day to build walls will over ride the delay to other trades.

Troopy you comment of cavities for all services is incorrect, often on block builds I have seen the narrower 100mm bessa blocks used for internal walls, they require chasing for services.
If the Hadrian can pre chase internal narrow blocks for services then Sparkies and Plumbers will love it.
