3 FOREWORD Until now, there has existed no published expert guidance on the de-commissioning, mothballing and re-commissioning of buildings a circumstance which has prompted the Service and Facilities Group of the HVCA to take this opportunity to come up with a definition of best practice for shutdown procedures for building services plant, covering the safety and security of the property, interim maintenance and eventual re-commissioning to full function. Drawing on expertise from within the Service and Facilities Group, the Guide to Good Practice on the Mothballing and Re-commissioning of Buildings provides a comprehenisive explication of the minimum requirements for mothballing building services within properties. As is usual with publications of this kind, specialist experts have been consulted and industry consultation has been sought. Acknowledgement must therefore be made of all those who gave their time and knowledge to the compilation and production of this guidance. I should also like to express my personal thanks for the long hours and hard work put in by both members and staff of the Association, and for their efforts to improve standards for our industry.

5 Guide to Good Practice Mothballing and Re-commissioning of Buildings Definitions OBJECTIVE The HVCA believes that the interests of the industry s customers and of it s member contractors can be enhanced and brought together by the publication of a straight-forward technical specification, (complementary to Statutory Requirements, European and/or British Standards) bringing a clear focus to practical and functional matters. This publication is therefore primarily intended to: Provide information for customers who are appointing (by competition or negotiation) a contractor. Provide a minimum standard for de-commissioning, mothballing and re-commissioning buildings. Provide a standard of practice that may be verified by independent assessment. STANDARD OF WORKMANSHIP The standard set by this publication is intended to be appropriate to most normal commercial, industrial buildings and relates to good practice in de-commissioning, mothballing and re-commissioning of properties without unnecessary elaboration. The HVCA intends this to be significant guidance that meets the requirements of relevant legislation that conforms to accepted industry best practice. QUALITY ASSURANCE This standard can be used as one criterion that will assist customers and specifiers in performing their important role of defining the standard of work they require. The HVCA anticipates that this standard will be complementary to existing quality assurance schemes and quality assessment schedules. SCOPE This standard covers de-commissioning, mothballing and re-commissioning of properties. This standard may be applied to projects in the U.K. and the Republic of Ireland. It is not intended for overseas work; however, some of it s provisions will be appropriate or may form a basis for overseas work. Specialist equipment such as passenger transport systems and fire suppression systems are not covered in this document and guidance should be sought from manufacturers operating and maintenance manuals. This publication makes use of terms should, shall and must when prescribing procedures: 1.The term must identifies a requirement by law at the time of publication. 2.The term shall prescribes a procedure which, it is intended to be complied with, in full and without deviation. 3.The term should prescribes a procedure which, it is intended to be complied with unless, after prior consideration, deviation is considered to be acceptable. HAZARDOUS WASTE/REFRIGERANTS Hazardous waste and refrigerant gases found on premises will require a risk assessment to determine whether they can be stored in situ during the shutdown period, or if they require disposal. The Hazardous Waste Regulation (England and Wales) 2005 replaced the Special Waste Regulations and brought some Controlled Wastes into the same regime for handling and disposal. All waste that is listed in the European Waste Catalogue (EWC) must now be handled under the requirements of the new Hazardous Waste Regulations. Under the Environmental Protection Act and the Hazardous Waste Regulations you have a Duty of Care to ensure that the company you select to handle your Hazardous Waste is operating correctly and will handle your waste in an acceptable and approved manner. HAZARDOUS WASTE SCOTLAND: Hazardous Waste produced in Scotland is controlled by the Special Waste Amendment (Scotland) Regulations 2004, even if the waste is to be transferred to England and Wales for recycling, the Scotland Regulations take precedence. The Regulations are managed by the Scottish Environment Protection Agency (SEPA). Any movement of such waste must be pre-notified to SEPA, 3 working days before the waste is moved. HAZARDOUS WASTE NORTHERN IRELAND: Hazardous Waste produced in Northern Ireland is controlled by the Special Waste Regulations (Northern Ireland) The Regulations are managed by The Environment and Heritage Service (EHS). Any movement of such waste must be pre-notified to EHS 3 working days before the waste is moved. PUBLICATION AND REVIEW User feedback on the wording or the requirements of the standard will be welcomed to assist in continued updating. 6
