Integrated Design Review Methodology for Critical Facilities Management and Maintenance

Critical facilities are expected to provide continuous performance in standard service conditions and in extreme events in particular. Continuity of performance is determined by the design redundancy, robustness and resilience. A framework for Integrated BIM based service life design review developed for planning of critical facilities. The framework aims at the execution of the design, construction, and commissioning of projects with whole life performance, operation, and costs planning. The methodology follows two phases: (I) Service life planning and (II) Design review. Service life planning is carried out through four stages: (1) Definition of the service regime; (2) Service Life Prediction of the building components; (3) Performance planning, and (4) Service Life Agreement. Design review (DR) is carried out for four building systems: structural safety and integrity, exterior envelope, interior finishing, and exterior infrastructures; and six electro-mechanical systems: Electric and power supply system, Water supply and sanitary, HVAC, Fire Protection, Elevators, and Communication and low voltage systems. DR follows four principles: (1) Durability; (2) Techno-economic service life planning; (3) Maintainability; and (4) Minimization of the Life Cycle Costs (LCC). A Design Review matrix developed for automation of the DR process: the DR matrix is composed of four leading key factors. Key leading factors are Durability, Maintainability, Service Life Planning and Design Guidelines. An integrated public-hospitality case study carried out and presented. © 2020 The Authors.
