Effective MEP Techniques and Design Strategy for Large Subsurface Metro Projects

摘要

This paper illustrates the challenges for any major large infrastructure subsurface railway project, to select and undertake a cost effective, manageable and optimum MEP design strategy across a large programme of work. The paper proposes methods to overcome such challenges which extend into procurement of equipment. The paper is intended to highlight the requirement to hand over MEP assets that allow the Railway Operator (RO) to undertake maintenance safely and in a cost effective way. This essentially means to organise and deliver a suitable common design and installation that allows flexible maintenance principles and an achievable Whole Life Cost (WLC) level. The detail in this paper promotes methods of design strategy that are arguably more suited to achieving a common approach to design and delivery. The argument is against one of a multiple type design approach and procurement strategy where projects may choose to adopt through the programme to reduce risk both organisationally and contractually. These are the following; 1. Optimum MEP Strategy and Common Components, 2. Prototyping MEP in Design, and, 3. Delivery and control techniques for MEP service route and space planning and access and maintenance (A&M).
