Hi, You don’t say who is the author of the maps and whether you can ensure whether they are in fact necessary for safety compliance, and if so, that they are done properly. The little I’ve learned on fire safety upgrades is in meeting the requirements of the local council and the Fire Brigade. I understand these are the bodies which rule on the various upgrade minimum features that are necessary to meet approved fire safety compliance. Also I’d guestimate that the building’s available budget, and the reasoning of yourself and the committee you speak of will help in arranging the procedure, with the body corporate, or their consultant working within the guidelines of the authorities.
Others will know more.
Good luck!
