Key Model Framework

2.1 O&M Input on Design for New Building

Design for maintainability emphasises the importance of timely integration of design and construction knowledge with O&M experiences into the project design in order to optimise building life.

Accessibility and maintainability should be considered, and incorporated in to the building system design, ensuring the ease, accuracy, safety, and economy of maintenance tasks within that system. Maintainability refers to the effectiveness and efficiency of maintenance activities. New working practices encouraged, such as Building Information Modelling for Asset Management (BIM-AM), require the involvement of asset owners and FMs to understand the information they require on handover. FMs should be involved during design stage and ensure the information handed over by the contractor fits their specific needs.

2.4 Emergency Preparedness

Building Emergency Preparedness is an effort to connect the emergency planning and response with the building users. The goal is to train personnel in basic emergency response actions who know the building and occupants and can act as a resource and liaison to the stakeholders and building users.

An emergency action plan should identify all the potential hazards associated with the HVAC Systems, with a personnel responsibility matrix for allocating appropriate resources. The written plan should become an action document, updated according to an appropriate timeframe to ensure accurate information, such as contact information, is provided.

2.5 Preventive Maintenance Procedures / Standards

The goal of Preventive Maintenance is to prevent equipment failure caused by fatigue, neglect, or normal wear, through replacing worn components before actual failure.

Maintenance activities include partial or complete overhauls at specified periods, and include oil changes, lubrication, minor adjustments, and so on. Typical procedures recommend that personnel record equipment deterioration upon any inspection to facilitate the replace or repair worn parts before any system failure. It is necessary to undertake preventive maintenance of installations and equipment to maintain efficient working order of the building's HVAC systems and their components. The HVAC systems require periodic inspection, testing and maintenance throughout their life cycle in addition to the need for overhauling, or replacement, at a certain age or interval, or due to specific issues or causes. These must be outlined specifically in a Preventive Maintenance Program.

The Preventive Maintenance Program must include the methodology and record for all actions that are necessary to maintain the efficient working order of the HVAC systems. The required maintenance procedures will be unique to each property and the installations and equipment within these facilities.

2.10 Incident Management

Incident management refers to the "the combination of facilities, equipment, personnel, procedures and communications operating within a common organisational structure, designed to aid in the management of resources during incidents". When a service is disrupted or fails to deliver the promised performance during service hours, it is essential to restore the service to normal operation as quickly as possible. In addition, any condition that has the potential to result in a breach or degradation of service ought to trigger a response that prevents the actual disruption from occurring. These are the objectives of incident management.

2.15 Structure and Qualification of O&M Team

Structure is the people, positions, procedures, processes, culture, technology and related elements that comprise the organisation. It defines how all the pieces, parts and processes work together. This structure must be totally integrated with the strategy defined for the organisation to achieve its mission and goals. Structure supports strategy. If an organisation changes its strategy, it must change its structure to support the new strategy. When it doesn’t, the structure acts like a bungee cord and pulls the organisation back to its old strategy.
