Book times for chopping boxes in walls

[stimpy]

Evening,

Anyone know the book/industry times for chopping 1g & 2g 35mm back boxes in concrete block and then fixing . All using power tools.

I know how long it would take me! But will be subbies... My luckins doesnt list it and my old spons only has chopping by hand times which I reckon my mum could do quicker...

TIA

I think there is sarcasm there.

I work in a factory environment where the general operators have timed jobs and have to make so many parts per hour, there were some jobs which were untimed and trusted operators were allowed to work away at their own pace, a new supervisor eager to make a name for himself ordered a time study and for targets to be introduced the result was the operators worked to rule and productivity was actually less on these jobs than the previous untimed output, i think the moral of the story is it'll take as long as needed.

Yes mate sarcasm was the intention

I think he was s referring to the sarcasm of the previous op with 1 and 2 hours respectively.

Just use an sds with comb chisel on the end, I could probably knock a box hole out in a minute then fix the box, but then again, if you are talking of engineering brick you are going to be mounting it in, then add a few more mins on.

Hmmm, anyone got anything actually useful to say based on the actual Original Post regarding book times??

Peppa Pig was funny mind

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!
