Just got a 5 storey house to do -advice needed ?

[Roger]

Big budget 200k plus,5 bathrooms,60k kitchen,very good day rate.Will keep me busy for months.We will be involved in the stripping out and old coppers getting a good rate currently .My plumber mate was rubbing his hands and then started talking about megaflows and all that.

Existing property has 3 phase going to 3 seperate single phase meters.Lots of bedsits so might have made billing easier ?
First thing to do ? after inceasing liability insurance as its in London !
Contact Electricity provider and get them to install a 3 phase meter.Earthing is via a galv strap to the casing of a 100amp isolater to the sheath of the incoming armoured.
Install a 3 phase distribution board and split phases over floor or have multiple phases on same floor ?
Power on one and lighting on other and so on.Kitchen on one phase,living room power on another ?
Whats best way to do it ?
Best make of dist boards ?
Want loads of stuff CCTV,scene lighting,alarms,cat 6 data throughout.
Big project for me ,feel a little out of my depth so much advice sort ,lots of wise heads on here.
Thank youi

I think 16mmMI is going to cost!,IMO armoured is favourable ,quite cheap,user friendly fairly bulletproof

Hi, the best way to tackle these sort of projects is a floor/board at a time. We`ve wired a few large mansions in the past, and if you try to think of it as a whole, you`ll get nowhere. A floor at a time, each circuit at a time. Finish with one circuit, on to the next.

I assume you`ll be running the alarm circuits from the initial three phase board? And that it'll be one circuit to cover the building? If so, i would leave these sort sort of circuits until the end, simply because by that time, you understand the construction of the building, and they should come faster.

Hows it going,Son,aint interfered,as been away,had no real input....Agree with last post..break it up into circuits,on different phases,keeping them away from each other,...Alarmsetc,should be communal,so if the distance isnt too great,youll manage on one phase,normally Landlords,by now,i assume you know that,Building control can be great help,when approached right...Good Luck!!!!!!!

 

[blackiel]

By the way...Armoured subs,All floors....No MICC..not worth it!!!

 

[blackiel]

Update,have not been on here for ages !
It all been rescheduled for the new year,planning problems have delayed the start of the work.They wanted to alter to much and have a fight on their hands now getting the revised (many times) plans through.At one point they wanted to go under the road with a basement Gym thing !
Thanks for the advice ,will try to post a bit more frequently

As you say, first thing to do is to contact the supplier, and get the incomer sorted. #Increase your liability insurance if you feel it needs it - £5M should be more than enough, and make sure your contract paperwork is watertight.

Second, and MOST IMPORTANT thing from your perspective - GET YOUR PAYMENT TERMS AGREED. If you're on a day rate for it, when do you invoice and get fund released, if it's purely staged invoicing, at what points can you raise a valuation?

For jobs over £10k now, we insist on staged payments - we have to - and it's normally 25% on delivery to site of materials, 25% at end of first fix witness testing, 47.5% on handover, and 2.5% retention for three months, unless varied for other reasons.

By the sounds of the job, it might pay you to price for, and get in a specialist designer - and get him to sign off on the design. You reduce your liability considerably this way.

For the CCTV, CAT6, alarms, and by the sound of the size of the property your fire alarm will be BS5839-6, probably grade LD1, and you'll need BS5266 emergency lighting too. Again, maybe worth pricing for specialists.....

As regards the fire, CCTV, alarms, emergency lighting and CAT6, happy to provide design and quotations for install and ongoing maintenance (requirement for the standards for both fire and emergency lighting), and effectively take that off your worry list.....let me know.

id stick a 3phase db at incomer
own db for kitchen
try and agree a db on say the middle floor for small power
if they are having lutron or crestron for lighting and automation ample supply at incomer for these submains
i tested a house with 2x32way lutron circuits 16x4 way mods in total
each mod was fed from a 16a rcbo in 2.5t+e
niccy man made me test each circuit as a submain to each mod and class a mod as a 4way db
6bed house with stables ,summerhouse and garages turned out to have 124 test sheets with 40 dbs

plan it well my friend to limit paperwork

Well were more than half way thru 2011, and if it hasn't started yet, i doubt if it ever will, not with this client anyway!!!

Not only that, .....the client has probably lost all of his money in the world financial crash. Serves him right too, if he was one of these greedy bankers or speculator types ...lol!!!
