8.0 _ Access & Maintenance Strategy

Statutory This report is prepared with regard to the Statutory Duties Design Engine Architects have Duties with regard to the design of buildings. Maintenance and Replacement Strategy The Studios, Coker Close The statutory obligations of those involved in the design of safe access for maintenance and Winchester SO22 5FF repair, stem from the Health and Safety at Work etc Act 1974. 10077315-DEA-ZZ-XX-HS-A-8001 WSMSE Safety Training +44(0)1962 890111 For construction, the Construction (Design and Management) Regulations 2015 (CDM 2015) [email protected] came into force on 6 April 2015, replacing CDM 2007. This places specific duties to those Strategy To Explain DEA’s Design for Maintenance and involved with the commissioning, management, design and construction of construction Replacement including provision for access and safe working www.designengine.co.uk projects. 22/03/19 Other health and safety regulations, such as the Workplace Regulations, and Building P01 Regulations requirements (Part K for instance) will also be relevant when designing for safe access. The Work at Height Regulations 2005 are of particular relevance to access issues. General This document describes the design strategy although there may be multiple appropriate Types of Notes ways to carry out any task. Final method statement to be provided by those carrying out the Maintenance Cleaning works. Work to clean the interior and exterior to keep it looking good, keep up performance (eg., Limitation view through windows or PV panel performance) and prevent premature deterioration. All persons undertaking access for cleaning, inspection, replacement or maintenance, or any Internal cleaning is also important to maintain a healthy environment Reference other purpose are to be competent operatives, adequately trained in the building specific Material equipment, layout and procedures. Inspection Work to check on the condition of the building fabric, information which should feed into the Cleaning and working areas to be secured and separated from public routes. Where planned maintenance process. cleaning is taking place above, areas below to be similarly secured. This applies both internally and externally. Planned maintenance – this can broadly be divided into two categories: This is a summary report that does not intend to provide a definitive record of the design Condition based – where elements are repaired or replaced depending on their condition. processes undertaken that resulted at this stage but collates the output of the design process For example the façade of a building, or a roof surface may be replaced where it has up to the current stage and outlines the proposals to date. deteriorated to such an extent that it is no longer watertight. Time based – where elements are repaired or replaced after a set duration, irrespective of Although the CDM regulations do not require the recording of risk management processes made by designers, it is considered good practice to do so. Such action allows reference their condition. This may be because their operation is critical, or simply because there is no back at a future stage and enables a designer to demonstrate that the task was means of ascertaining their condition. Examples of this are filters to pumps, lamps, or accomplished, in accordance with most QA procedure requirements. batteries in UPS systems. This report is intended to demonstrate the proposed strategies and not provide fully detailed Access for Unplanned maintenance – this is where maintenance is required as a result of unforeseen information of the systems.

They are easy to relocate and provide a good platform from which one or two people can work safely. They are however subject to misuse and have resulted in serious Iddon and Carpenter (2009) accidents usually through toppling of the tower. “Safe access for maintenance and repair. Guidance for designers” Second Edition 2009, CIRIA C686, London, 2009, Permanent access walkways with fall arrest and fall restraint systems are provided to give access to facades where other forms of access would be difficult. “The Construction (Design and Management) Regulations 2015 (CDM 2015” Fall arrest and fall restraint systems are used as a last resort to provide personal protection for Design Engine Architects (October 2016) less frequent access areas where other means of access are not possible. “The Construction (Design and Management) Regulations 2015 (CDM 2015) PRACTICE GUIDELINES“ Mobile elevated working platforms (MEWPs) are now available in a variety of different sizes and designs Scaffold systems come in many different forms of scaffolding systems and they offer great flexibility as they can be designed to accommodate virtually any shape or structure. Temporary Ladders are used for infrequent access to areas where other forms of access are not possible. 10077315-DEA-ZZ-XX-HS-A-8001-Maintenance and Replacement Strategy.numbers Design Engine Architects Ltd 0 10077315-DEA-ZZ-XX-HS-A-8001-Maintenance and Replacement Strategy.numbers Design Engine Architects Ltd 0 Version 1 Date:07 November 2017 Version 1 Date:07 November 2017
