Specification clause for STEP ALERT Corduroy Hazard Warning by urbanfinish.

Corduroy Hazard Warning treatment to be provided by retro-fitting of 20x6mm half round fittings as manufactured by urbanfinish. These are to be fitted to 50mm spacing and, as per the guidance notes produced in accordance with DDA/Part M Regulations, to a depth of 800mm starting 400mm back from top/bottom step. Allowance is to be made for coverage 400mm beyond the width of the steps each side. Material to be Stainless Steel/Brass/HD Composite to RAL colour.


The corduroy surface provides a hazard warning to visually impaired people, for example: steps, level crossings or the approach to on-street light rapid transit (LRT) platforms. It is also used where a footway joins a shared route.

It conveys the message 'hazard warning, proceed with caution'. Part M and DDA corduroy fittings in HD composite - retro-installed into any pavement or floor surface anti-slip finish - HD Zircol Composite Step-Alert corduroy fittings are manufactured precisely to the Part M and DDA regulations; exactly to the recommended dimension and achieves a neat finish on all surfaces.


The profile of the corduroy surface comprises rounded bars running transversely across the direction of pedestrian travel. The bars are 6mm (± 0.5mm) high, 20mm wide and spaced 50mm from the centre of one bar to the centre of the next (Figure 02). It is recommended that the corduroy surface be in a contrasting colour from the surrounding flooring to assist partially sighted people and stainless steel is perfect for this.


The corduroy surface can be used for any situation (except at pedestrian crossing points where the RockArt TopGrip blister tactile fittings should be used) where visually impaired people need a hazard warning to be advised to proceed with caution, for example:

•the top and bottom of steps;

•the foot of a ramp to an on-street light rapid transit (LRT) platform, but not at any other ramps;

•a level crossing;

•where visually impaired people could inadvertently walk directly on to a platform at a railway station;

•where a footway/footpath joins a shared route.

The Disability Discrimination Act (DDA) 1995 has placed certain obligations on property owners, businesses and organisations to make ‘reasonable adjustments’ to the physical features of their buildings that can act as a barrier to entry for disabled people. In short this can mean putting in a ramp to replace steps, or highlighting the edges of steps for people with a visual impairment.In England and Wales, building design and construction is governed by the Building Regulations. These regulations comprise a series of requirements for specific purposes: health and safety, energy conservation, prevention of contamination of water and the welfare and convenience of persons in or about buildings. Part M of the Regulations sets minimum legal standards for access and use of buildings by all building users, including disabled people. Since a requirement for access was first introduced in 1985, there have been a number of changes to and extensions in the scope of access regulations. The regulation avoids specific reference to, and a definition of, disabled people. This inclusive approach means that buildings and their facilities should be accessible and usable by all people who use buildings - including parents with children, older people and disabled people.

Previously, Part M covered new buildings and extensions to existing buildings. The 2004 revision brings Part M into line with other parts of the Building Regulations by extending its scope to include alterations to existing buildings and certain changes of use.Approved Document M

Building Regulations are supported by 'Approved Documents' which give practical guidance with respect to the regulations. While their use is not mandatory - and the requirements of regulations can be met in other ways – Approved Documents are used as a benchmark by the local authority. The new Approved Document M (AD M), published in November 2003, offers technical guidance on providing access to and within buildings. It is informed by the relevant British Standard (BS 8300:2001 (Incorporating Amendment No.1) Design of buildings and their approaches to meet the needs of disabled people – Code of practice), although the British Standard also contains guidance on issues that are not appropriate or realistic to control under Building Regulations approval and inspection procedures, such as interior decoration and the selection of door ironmongery. Dimensional criteria in the new AD M are largely in accordance with BS 8300:2001. Where there are differences, these result from accumulated experience fed back to the Government during its consultation on the new AD M, and this should be followed in preference to dimensional criteria in BS 8300:2001.


It is important that reference is made to AD M for details of the circumstances in which Part M applies and what provision is required.


Disability Discrimination Act 1995

From 1 October 2004, under Part 3 of the Disability Discrimination Act 1995 (DDA), service providers have a duty to make reasonable adjustments to overcome physical barriers to access.
