Hoarding can be erected using a modular system or be a bespoke installation. It can be made using a wide range of materials, such as steel, timber or plywood, which may be re-useable or disposed of after use. Hoarding can incorporate barriers, gates and viewing windows, and may be used to display warning and information signs.
This article provides an introduction to the design of conventional timber hoardings using plywood sheets.
The design of timber posts follows the same principles as the design of vertical structural elements formed from other materials. Extreme fibre stresses or buckling due to applied axial forces are the key components affecting a post’s ability to perform. The major difference is the anisotropic nature of timber, which, for vertical elements, has a significant impact on the assessment of their performance as a structural member. The design of timber elements in the UK, according to current codes of practice, is based on limit state theory. This Technical Guidance Note adopts this approach to describe the design of timber posts. The note assumes that the reader is familiar with the use of coefficient factors prevalent within BS EN 1995-1-1 (Eurocode 5), as described in Technical Guidance Notes Level 1, No. 18 Design of timber floor joists and Level 2, No. 14 Design of unrestrained timber beams.
This article provides a brief introduction to demolition practice in the UK, addressing the more technical aspects requiring engineering input.
Falsework is defined in BS 5975 as a temporary structure used to support a permanent structure while it is not self supporting. This article focuses on the use of proprietary equipment for the support of fresh concrete to horizontal surfaces. The principles and methods described are broadly applicable to all falsework.
