What i feel is, Rather than mentioning 1st fix, 2nd fix, final fix, or conduits...it should be defeined inder particular systems.. like

fire fighting systemn
commnication system
Fire alarm system
HVAC system
Plumbing system
Poweer & lighing system etc

In these system u can defeine the activities like conduits, pipes, swiches, diffuser etc...It will be clear to one who going to read/refer the programmes & will be easy for tracking & to have better control on site works....

I have suggestion Richu

1.Generally underground works are mentioned under seperate WBS named underground works where we mention underground piping works especially for drainage and sewer works they does not come under first fix activities

2.Sleeves comes under a WBS called builders work they does not come under first fix activities ,even slab conduiting could be classified under this WBS but it has an option it can also be mentioned in first fix

3.Rest of yours is perfect

4.I would advise you open up WBS individually for electrical, mechanical and plumbing do not group as M&E fix or works for the ease of tracking ,cost and resource loading

5.Be specific in mentioning activities for example you wrote cold & hot water supply under 2nd fix ,please mention what work you going to carry out for example cold & hot water supply piping works

6.so that your programme is easily read by others without any communication problem

7.I guess it would helpful to you

Regards
Shahul

Dear Richu,

You already are at a good level of detail. You don’t have to go up to the classification of 1st, 2nd and 3rd fixes. I would suggest that you mention them as you already detailed them as activities when you need them in between the civil works.

With kind regards,

Samer

Dear Jacob,

The same principle applies. If you are talking about a cable ladder, then you have 1st and 2nd fix only. If you are talking about piping, then you have 1st fix only.

With kind regards,

Samer

MEP 1 st fix : Those which start along with block work and continue till completion of plaster eg.Duct hanger&support ,pipe hanger&support,fixing G.I conduits,back box,marking on block walls ,cutting & chasing install of concealed pipes in wall and so on

MEP 2 nd fix : Major part of building utility system starts after completion of plaster eg.ductwork installation & insulation,chilled water pipe installation & insulation,FCU/AHU installation,water heater installation

MEP final fix : Generally covers all exposed items eg. electrical light fixtures,grilles& diffusers, sprinklers and so on
