Hello !
Im from the UK, with several years hands on experience at trade level in building.
I am now working here in the UAE and I am looking a a building tender and my friend, an Indian QS I am working with, is insisting that in my tender programme I call MEP fit out as per the below...
1st Fix - e.g waste pipe penetrating ground slab. (before concrete)
2nd Fix - e.g light switch box (after concrete, before plaster)
3rd Fix - e.g light fittings (after plaster)
In the UK I have only ever heard terminology for 1st and 2nd fix applied to MEP and carpentry. I.E 1st fix = before plaster, 2nd fix = after plaster. I can understand his point but id rather seperate the 1st fix activity into 2 parts, and call the third activity 2nd fix, as per all my previous experience.
Hes a good guy and has worked here in UAE many years so I have no reason to doubt him, he sais the consultants may look at this in their tenderevaluation....Its just that being English I would rather change the world than have the world change me!
Would be intersting to hear if this ’3rd fix’ is in frequent use anywhere else in the world or just in the UAE ?
Sorry to be such a bore, please dont tell my girlfriend I actually spend time thinking about this sort of stuff...
Cheers,
Phil

Oldest first- 0Mike Testro ·Hi Phil - Welcome to PP.
Use the local terminology and follow your friends advice.
Don’t try to change the world you are in - you will lose any potential respect.
In the UK there are usually 3 stages in M&E (MEP) operations.
1st Fix - before plaster
2nd Fix - After plaster
Finals - Luminaires - taps - grilles etc
In a detailed M&E programme I have used many more activities in each of the sections.
As Anoon says - write a detailed definition of what you have included in each section.
Best regards

As explained by Mike
1 st fix could be builders works ,activities before plaster
2 nd fix after plaster
3rd or final fix were it is last step of classification of MEP installation .It is preferential construction sequence
As of my knowledge there is no 4 th fix and so on
Even you could refer links posted by Pinan for further clarification
There is another classification in MEP installation that is BOH & FOH i guess that is not required
