This is an area neglected by most. The supports of individual MEP systems and RCP are different and are governed by many factors like the load, seismic condition, spacing etc.
And this co-ordination will be least considered during design development stage because the design department has a tendency to handover this task to the installation team.
Irrespective of whose responsibiliy (design or installation), the support systems of each service needs to be coordinated to avoid clashes.
There are certain things which should be considered while doing this:
1. Sequence of installation
Once the MEP co-ordination design is final, the sequence of installation will be established. At this point, most individual service engineers (in installation team), will go ahead as per this. But if the support co-ordination is not done prior to installation, then it will lead to plenty of reworks.
A small study on the supports by all the three MEP departments will help in a combined decision on which all supports can be installed first and which needs to wait will help avoid this rework.
2. Same Support for different services.
If the route of more than one service is either parallel or crossing at many points, then the support can be designed in such a way to hold them together. Please note constraints mentioned in the earlier blogs. If carefully checked with all the MEP services together, then this task can be very useful.
But note that these are subjected to the approval of the consultant / specification from project to project.
3. Span adjustment
The support coordination helps in adjusting the span (within acceptable limits) of support horizontally as well as vertically. This is usually useful when a heavy HVAC duct crosses other MEP services.
4. RCP Support
We MEP guys generally neglect this part. The RCP supports used to hang the False ceiling from the soffit needs to be taken care of. Vertically there are options available for adjusting the RCP support. But horizontally the support run takes a height of 1cm to 5cm. So our MEP services should be atleast 15 cm above the top of false ceiling to be on the safe side (Please read the previous blog on Electrical part).
