Help with steps to get utilities in

[WWilts]

Commencement in 5 weeks. Electrics, water, gas suppliers all lined up and paid. Utilities all will come in from public highway. Electric meter position agreed with supplier

Can't work out 

1) Sequence of steps so that not too much money is wasted on getting the utilities and foul drainage in place. Assume ignorance on my part.

2) Route of ducting

 

What would you do?

 

 

PS

There will be a pumping chamber for new dwelling foul drainage, probably at the corner of the existing dwelling rear garden
Builder needs electrics and water. He will use a lot of the back garden of the existing dwelling as his working space

More specifically,

option 1: install foul drainage at end, after scaffolding down. New trench. Only temporary electrics and water connected at start

option 2: install foul drainage & ducts for utilities at start, same trench

Not sure what to choose

[nod]

Many builders use option 1 due to time restraints 

I would always get all the drains and services (Ducting) in with the foundations

If you do this after the scaffolding comes down You start again with all the mess and it all gets tramped into your new home

Build a small services station at the electric meter point, run electric, utilities, broadband etc there and dig a single trench with four conduits in Electric, Water, Comms, Spare to the house from there. You cannot do that with the foul drainage although there is nothing to stop you sharing the foul trench with the conduits, it just needs to observe all the spacings. We did this its been a godsend as everything is in one place, we can isolate the house on all the services and everything is readable at the box. I have still to solve the smart meter transmission to the house as they all seem to rely on proprietary wireless and that is way out of range, there must be an answer to this but I have not run across one yet. (I can read it it via the APP but only after it has been to our supplier.)
