Book times for chopping boxes in walls

[uksparks]

I accept what you want, but... Why do you actually care? It takes as long as it takes, one wall is quite different to another, then if it's those silly blocks with hollow centres, you then need a tonne of filler of similar to fix it back up.

It's not really something you can put a time to as there's variables and other factors involved. It's not like piece work in a factory where every item is identical.

The moral of the story is if you go messing good blokes about just to try to make a name for your self then you'll get just that - but it won't be in the Bible.

Leviticus 25:43New International Version (NIV)

43*Do not rule over them ruthlessly,*but fear your God.

Theres always something in the bible, after all it is sunday morning

That which is not measured is not managed. I think someone has been on a management course.

5 mins to make correct size hole for 1g, 8 mins for 2g.
3 mins to get metal back box securely fitted, hole knocked out and rubber grommet in.
Add 5-10 minutes if brick/concrete starts crumbling and its difficult to get rawl plugs in.
Those would be my times (approx)

tend to agree with this, its a case of do you want it done properly or a bodge...

Why do I actually care? Great response!??.. :6:

I care because I'm pricing 2 very large jobs from drawings and rather than using my regular methods of guesstimating through I'm trying out the BOOK method of pricing as these projects are very large for me - there are book times for everything from conduit installs to blokes scratching their arse - this is how all the estimators on large firms price work.

I'll admit I left out its solid concrete block on new build....

A sensible answer . These are near my times, with walking round site from one spot to another, dragging drill, trannies, leads etc I'd reckoned 15 mins average for the process.

Was just interested in seeing what the actual average book time was...

If it's a large job is the chasing not being done by others?

All of the big sites I have worked on all we had to do was mark up the chases and the 'chasing man' would come along and smash them out.

Yes, it does seem to infer this in the base spec but there's some ambiguity as to its scope so I thought I'd get a figure anyway.

I've also had many times when the " chasing man" has done such a **** job that we end up ****ing around quite a bit doing correctional works!... But it would certainly be fab if the job was done by others!

 

[davesparks]

Then ask for clarification of the base spec!

As I pressed submit I thought to myself " he's gonna say get the spec"!!! Haha..

The developer is a mate and is woolly and busy, he's suggested I allow both scenarios for now....

If you're talking about LARGE firms and LARGE jobs....somehow i don't think they'll be wasting their time counting hundreds of individual sockets and splitting into 1st fix, wiring, 2nd fix, etc....it's average price per socket, full stop.

This Developer seems a bit hit and miss, make sure you dot the Is cross the Ts and check to the enth degree these "mates" will screw you for everything if you ain't careful, bit of a chancer by the sound of it, seen plenty of them as soon as something goes wrong, hes not to blame. I told him this that and the other as long as the ess H one T don't stick to him/her.

I suppose everything is measurable even chasing out walls, look at your book then, time and motion and all that, depends how good the guys are really doing that work.

 

[londonfire]

I think another question should be how long to chase and drill down behind the skirting, then thread the cables up.
Sounds easy but some times with a joist in the wrong place. Ages!

lift the floor first to check is good advice, seen a few people get stung by that.


coving is a lot worse than skirting

You can't account for the unseen, just add a clause in your quote foe any unseen problems as described in the previous post, but actually its part and partial of any wiring job of this sort, do it as an extra time only.

add in your clause, for breeze block walls only, additional charges and time constraints might apply on other surfaces

It's fine , I've done many projects with him, hundreds of £Ks worth of work over the years. He just cba to find out. Which is fine so long as I specify.

These 2 developments are the largest we've both done hence the basic spec was drawn up by a large firm and tenders have gone out. All previous work have had no tenders, just me and him with open book and agreed percentages. That will not be the case on these.

I don't agree they have to have a schedule works which can only be drawn up by accounting time. Certainly not with these firms. Besides, sockets and switches play a small part in the make up of this job - there's tray, panel boards, ashps , mvhr, pv, controls, specialist wiring, lighting scene controls, full av, data , hd, security, fap, cctv blah blah blah.
