ISO 55000:2014 Asset management. Overview, principles and terminology  CONSTRUCTED ASSETS Reasons for the interest in physical asset management: growing financial, safety and environmental risks; growth of capital intensity in some areas of Prof.G.PAGANIN industry; pressure for higher profitability and return on assets; aging of asset systems; increased requirements from the safety and environmental point of view;  Terminology (ISO 55000 “Asset management — Overview, principles and terminology”) How can we define the term ASSET? Prof.G.PAGANIN "asset" is defined as something that has potential or actual value to an organization. Value, however, will mean different things to different people and different organizations. Value can be tangible or intangible, financial or non-financial.  Terminology (ISO 55000 “Asset management — Overview, principles and terminology”) Asset types are groupings of assets having common characteristics that distinguish them as a group or class for asset management purposes. Examples of asset types include but are not limited to Prof.G.PAGANIN physical assets information assets financial assets intangible assets critical assets information technology (I.T.) assets infrastructure assets moveable assets human assets  BUILT/CONSTRUCTED ASSETS The factors which influence the type of assets that an organization requires to achieve its objectives, and how the assets are managed, include the following: Prof.G.PAGANIN the nature and purpose of the organization; its operating context; its financial constraints and regulatory requirements; the needs and expectations of the organization and its stakeholders. Source: ISO 55000 Asset Management  BUILT/CONSTRUCTED ASSETS Asset management decisions (technical, financial and operational) collectively enable the achievement of the organizational objectives. This includes: 1) the implementation of risk-based, information- Prof.G.PAGANIN driven, planning and decision-making processes and activities that transform organizational objectives into asset management plans; 2) the integration of the asset management processes with the functional management processes of the organization, such as finance, human resources, information systems, logistics and operations; Source: ISO 55000 Asset Management  terminology need: What is necessary for or desired by the user. NOTE. A need can be declared or undeclared; it can be an existing or a potential one. user: Any person or organization for which the product is designed and which exploits at least Prof.G.PAGANIN one of its functions at any time during its life cycle. NOTE. A user can be an external or internal customer. product: Result of activities or processes. NOTE 1. A product can include service, hardware, processed materials, software or a combination thereof. NOTE 2. A product can be tangible (e.g. assemblies or processed materials) or intangible (e.g. knowledge or concepts), or a combination thereof. NOTE 3. A product can be either intended (e.g. offered to customers) or unintended (e.g. pollutant or unwanted effects).

Building performance: the real behavior of the building system and / or its parts under actual Prof.G.PAGANIN conditions of use. Performance building are usually classified into: a) environmental performance; b) technological performance.

The Regulation provides a common technical language to assess the performance of construction products. It ensures that reliable information is available to professionals, public authorities, and consumers, so they can compare the performance of products from different manufacturers in different countries.  CPR essential requirements 1. Mechanical resistance and stability The construction works must be designed and built in such a way that the loadings that are liable to act on them during their constructions and use will not lead Prof.G.PAGANIN to any of the following: (a) collapse of the whole or part of the work; (b) major deformations to an inadmissible degree; (c) damage to other parts of the construction works or to fittings or installed equipment as a result of major deformation of the load-bearing construction; (d) damage by an event to an extent disproportionate to the original cause.  CPR essential requirements 2. Safety in case of fire The construction works must be designed and built in such a way that in the event of an outbreak of fire: (a) the load-bearing capacity of the construction can be Prof.G.PAGANIN assumed for a specific period of time; (b) the generation and spread of fire and smoke within the construction works are limited; (c) the spread of fire to neighbouring construction works is limited; (d) occupants can leave the construction works or be rescued by other means; (e) the safety of rescue teams is taken into consideration.  CPR essential requirements 3. Hygiene, health and the environment The construction works must be designed and built in such a way that they will, throughout their life cycle, not be a threat to the hygiene or health and safety of workers, occupants or neighbours, nor have an exceedingly high impact, over their entire life cycle, on the environmental quality or on the climate during their construction, Prof.G.PAGANIN use and demolition, in particular as a result of any of the following: (a) the giving-off of toxic gas; (b) the emissions of dangerous substances, volatile organic compounds (VOC), greenhouse gases or dangerous particles into indoor or outdoor air; (c) the emission of dangerous radiation; (d) the release of dangerous substances into ground water, marine waters, surface waters or soil; (e) the release of dangerous substances into drinking water or substances which have an otherwise negative impact on drinking water;  CPR essential requirements 4. Safety and accessibility in use The construction works must be designed and built in such a way that they do not present unacceptable risks of accidents or damage in service or in operation such as slipping, falling, Prof.G.PAGANIN collision, burns, electrocution, injury from explosion and burglaries. In particular, construction works must be designed and built taking into consideration accessibility and use for disabled persons.  CPR essential requirements 5. Protection against noise The construction works must be designed and built in such a way that noise perceived by the occupants or people nearby is kept to a level that will not threaten their health and will allow them to sleep, rest and work in satisfactory conditions. Prof.G.PAGANIN 6. Energy economy and heat retention The construction works and their heating, cooling, lighting and ventilation installations must be designed and built in such a way that the amount of energy they require in use shall be low, when account is taken of the occupants and of the climatic conditions of the location. Construction works must also be energy-efficient, using as little energy as possible during their construction and dismantling.  CPR essential requirements 7. Sustainable use of natural resources The construction works must be designed, built and demolished in such a way that the use of Prof.G.PAGANIN natural resources is sustainable and in particular ensure the following: (a) reuse or recyclability of the construction works, their materials and parts after demolition; (b) durability of the construction works; (c) use of environmentally compatible raw and secondary materials in the construction works.  USER’S NEEDS SERVICEABILITY Serviceability: the capability of a building, assembly, component, product, or construction to perform the function(s) for which it is designed and used. Prof.G.PAGANIN Evaluation: part of a performance statement, consisting of the method(s) of assessing conformance of the element being addressed to the criteria.The evaluation states the standards, inspection methods, review procedures, historical documentation, test methods, in-use performance, engineering analyses, models, or other means to be used in assessing whether or not a criterion has been satisfied.

As technical specifications As performance specifications Prof.G.PAGANIN  User’s needs “OUTPUT SPECIFICATIONS” for PFI The Output Specification is the basis on which the local authority and its stakeholders state in output terms what they need to achieve from the facilities and services to Prof.G.PAGANIN be provided. It helps to frame the bidders’ response to the Invitation to Negotiate (ITN). The Output Specification should detail what needs to be achieved, not how it is to be achieved.

Prof.G.PAGANIN – Be clear, concise and unambiguous. – Give the potential bidders sufficient information to decide and cost the facilities and services they will offer.
