In one of our project, we have a underground utility tunnel of1.5 km long, 6m height and 8m width. It consists of steel pipes & cables. and one way for service car ( small car to help maintenance team in travel through tunnel) .
Please give your opinion on:
- the tunnel air conditioned and protected by sprinkler system but not have any smoke management system,is it ok as per NFPA ? if not please help me to find rate of air change required to smoke extraction system.
