BS 8544:2013

This standard BS 8544:2013 Guide for life cycle costing of maintenance during the in use phases of buildings is classified in these ICS categories:

• 91.040.01 Buildings in general

This British Standard gives guidance and recommendations on undertaking LCC of maintenance during the in use phases of facilities or constructed assets. It covers buildings, systems, assemblies, components, tasks/actions, resources and materials.

NOTE 1 The guidance covers maintenance planning during the in use (see 3.1.26) phases of a facility’s life cycle.

This British Standard also gives guidance and recommendations on the planning and prioritization, budget-setting, optimization, implementation and monitoring of life cycle programmes of maintain and/or renewal works.

The guidance includes asset surveys and employer’s maintenance management aspects of operation (as defined in BS ISO 15686‑5) that are needed to plan and manage maintenance delivery including life cycle works.

This British Standard is intended for:

1. public and private sector employers;

2. PFI/PPP/PF2 consortia;

3. property portfolio owners and occupiers and their investors/funders;

4. estate managers, managing agents and facilities managers;

5. building surveyors and engineers;

6. engineering services and maintenance contractors;

7. quantity surveyors and cost management practitioners;

8. designers, constructors, insurers and procurement groups.

This British Standard applies to most types of facility. Its application is, therefore, wider than buildings alone and extends to other structures and forms of construction to accommodate diverse needs.

NOTE 2 See RICS NRM 1, Appendix B [1] for a list of functional unit types of facility and equivalent functional units associated with each.

NOTE 3 See B&ES SFG20 [2] for industry standard task schedules for planned preventive maintenance along with guidance on how to customize the annualized maintenance programmes by function and service levels.

NOTE 4 See CIBSE Guide M [3] for reference economic life expectancy data for buildings and services and guidance on how to apply to project and in use situations using factoring methods.

This British Standard covers the interoperability of LCC of maintenance with BIM. It is also aligned with the soft landings core principles of proving (or improving) performance post occupancy.

NOTE 5 Some references have been provided throughout the text to highlight where aspects of these might be relevant.

This British Standard does not provide guidance on the assessment of the operation (including energy and carbon costs), occupancy or end of life costs or whole life cost (as defined in BS ISO 15686‑5).

Facilities maintenance management and procurement of facility-related services are specialist areas that link with LCC of maintenance and are covered in detail in BS 8210 and BS 8572.
