Mechanical Design Principles

This paper is written for use by the designers of Stations, Shafts and Portals.

The purpose of this paper is to clarify the minimum performance requirements for the design criteria, including temperature range and ventilation, for each room type and any particular system requirements.

With an agreed set of minimum performance requirements every opportunity will be made to:

These principles should accompany a set of Mechanical Design Criteria.

The strategy at each Station, Shaft and Portal for cooling and ventilating, as developed by designers, and how each system is to be applied needs to address the minimum performance criteria required.
