14 Barry’s Advanced Construction of Buildings Supporting information Further construction information which supports this text and volume one can be found on the Virtual Site http://www.leedsmet.ac.uk/teaching/vsite/menu.htm. The web site has photographs, videos and case studies which compliment the topics dealt with in these publications. Images of plant, equipment and construction technology can be downloaded to support project work and student presentations.
2 Scaffolding, Façade Retention and Demolition With the exception of some modular build projects, scaffolding is required to provide a safe and convenient working area above ground level. Scaffolding and associated temporary supports are also required for work on existing buildings, including repair, maintenance and refurbishment projects (see also Chapter 11). This chapter describes a number of different types of scaffolding systems to suit a variety of circumstances. Special structures to support the façade of existing buildings in façade retention schemes are also described. This is followed by an overview of factors coming under the broad heading of demolition, including the recovery and reuse of building materials and components and the recycling of construction waste. 2.1 Scaffolding There is a limit to the safe working height at which a worker can access the building work from ground level. Therefore some form of temporary support is required to provide a safe and convenient working surface. This is known as scaffold or scaffolding. Scaffolding is used on new-build projects and for work to existing structures, including maintenance and repair work. The temporary structure needs to be structurally safe yet also capable of rapid erection, disassembly and reuse. Functional requirements The primary functional requirements for scaffolding are to: ❏ ❏ Provide a safe horizontal working platform Provide safe horizontal and vertical access to buildings Scaffold may be owned and maintained by a contractor, although it is more common for the scaffolding to be hired from a scaffolding subcontractor as and when required. Temporary structures must be designed to suit their purpose by a competent person (e.g. certified structural engineer). Scaffolding must be erected, altered and dismantled in accordance with the National Access & Scaffolding Confederation (NASC) guidance document SG4 for tube and fitting scaffolds or the manufacturer’s erection guide. Table 2.1 shows the structures that need to be designed, and further information can be found on the Health Barry’s Advanced Construction of Buildings, Third Edition.
