Our trained staff are always on hand to give advice on all aspects of specification, legislation and best practice guidance to ensure each project reaches the optimum level of quality, finish and performance. Laidlaw is able to offer a wide range of architectural products that combine design and function across a broad range of product categories. By working closely with manufacturing partners to ensure consistent quality and performance and by keeping up to date with market requirements and technical specifications, Laidlaw remains at the forefront of the markets it serves. Having prepared a detailed site survey or from architects drawings, we will prepare a full design schedule of all the handrail or balustrade requirements including a full bill of materials.
Complete supply and fit Laidlaw offers a complete supply and fit service, from producing quotations from architect‘s drawings or bills of quantities, to on-site measurements, production drawings for customer approval, manufacture and on-site installation. A Laidlaw Technical consultant is always on hand to advise on any aspect of Handrails and Balustrades. Guidance on regulations and legislation Laidlaw trained staff can offer guidance on all aspects of Building Regulations and legislation including all aspects of DDA compliance. Component based systems
To keep on-site work to a minimum we assemble as much of the handrailing or balustrading as possible in the factory. Not only does this limit the number of section joints it also ensures that where there are joints or changes of angle the quality of the joint is a precise machined connection.
Our component based systems have a number of fundamental advantages: • Stock of key components ensure quick delivery • Factory assembly enables quick installation • Superior aesthetics to systems to which are built on-site because there are no unsightly welds, deformations of bends or poor aesthetic finish • Consistently high quality finish • Demountable components make it easy to repair • All components are recyclable.

Where the design and installation of a product affects the safety of its users, it is not an occassion for compromising on quality. There is no doubt that cheaper handrails and balustrades can be produced but the true cost in terms of safety and the life expectancy of such products can not be compared to the highly engineered quality of a Laidlaw handrail and balustrade. Not only is the finished article inferior aesthetically but there are significant performance deficiencies to make the on-site construction unsuitable for most applications. You can see examples of this on page 4.

WHY IS A GOOD HANDRAIL SYSTEM SO IMPORTANT?
The installation of a good quality handrail and balustrade system can have a significant effect on the way we interact with the built environment. A well designed system using quality materials and construction can enhance the visual and tactile nature of a building and will strongly influence the way in which the building is perceived as a welcoming place to be. From a purely functional view point, the handrail and balustrade solution will determine how accessible the facility is and will have a direct bearing on the health and safety of anyone who uses the building.
Slips, Trips and Falls Of the many statistics about slips, trips and falls, perhaps the most poignant is that in 2007 the proportion of major injuries due to falls from height was overtaken for the first time by those resulting from slips, trips and falls on the same level (source www.hse.gov.uk). They accounted for almost 11,000 or 38% of all major injuries and more than 27,000 of over ‘3 day’ injuries in the workplace. Running and walking injuries are not, however, industry specific. In schools for example, where pupils tend to be oblivious to hazards, rates continue to be high. In 2005/2006 8,367 injuries resulting from slips and trips were recorded, 5,440 of them involving children under the age of 16 and 1,357 involving employees. Whilst the evidence points to a reduction in falls from heights (due probably to the fact that the seriousness of the injuries resulting from such falls places more emphasis on reducing them) sadly, the same cannot be said of slips, trips and falls which show little sign of reduction. The provision of adequate handrailing is a major factor in reducing the likelihood of slips, trips and falls on stairs and on the same level. Guidance on stairs and handrails in buildings other than dwellings, set out in Approved Document M, indicates that handrails must be designed to accommodate all users, including children. They must be continuous and terminate beyond the top and bottom of a flight in a way that reduces risk, for example, of clothing being caught. In busy environments with wide staircases such as schools, additional rails are needed to divide the flight into channels. It may not be possible to ensure that these additional rails are actually used, but narrower aisles control traffic flow and place stair users in closer proximity to a point of safety. In addition to continuous support, the rails also need to provide adequate grip. The amount of grip is influenced greatly by the diameter of the rail and this can be improved by the use of smaller diameters of 35mm for example. However, being able to grip all round the rail brings the hands constantly into contact with the rail supports, forcing the user to change their grip. The optimum solution therefore is a balance between the diameter required for grip, providing comfortable support and being able to maintain the support along the full length of the rail.
Contrast and Visual Impairment Research has shown that for partially sighted users, high levels of contrast between the rail and the background are desirable. This contrast is most reliably expressed by reference to their Light Reflectance Value (LRV) rather than colour. In the 2004 edition of Approved Document M and the 2005 amendment to BS 8300, the desirable differences in LRV were quantified. Measured on a scale of 0 - 100 with jet black equivalent to ‘0’ and perfect white ‘100’. Relative differences between the rail and background were established at 30 points of difference. However, it is recognised that visual perception is affected by the relative area of surfaces and aspects such as texture, form, metallic or gloss levels. Within the 2009 revision to BS 8300 it has been acknowledged that 20 points of difference may be adequate in producing sufficient contrast provided levels of illuminance are above 200 lux.
LRV values are measured using a Spectrophotometer

WHY CHOOSE A LAIDLAW SYSTEM?
It is true, cheaper handrails or balustrades can be achieved but what is the true cost of this kind of product? We have all experienced a ‘site welded‘ tubular steel painted handrail. The life of such an installation is extremely short and should never be compared with the engineered and highly finished quality of a Laidlaw handrail system (left). Not only is the finished article inferior aesthetically but there are significant performance deficiencies to make the on-site construction unsuitable for most applications. • Sharp welds must be ground smooth and this cannot be achieved all round a handrail which is fixed close to the wall • Site finished handrails will very quickly deteriorate through even normal use, leaving the steel substrate exposed and vulnerable to corrosion • Thin nylon coated systems may seem adequate to begin with, but with even modest use the thin coating can soon become thin and cracked, exposing the steel substrate which quickly deteriorates • Site formed bends and curves can rarely be produced smoothly or with an even surface Certainly not all alternatives are as poor as the examples shown below marked with a red cross, but there are countless examples of the type of deficiencies which are typical of on-site manufactured and lower quality bespoke systems. The contrast is the high quality materials, manufacture and detailing of the Laidlaw handrailing shown throughout this brochure.

HANDRAIL & BALUSTRADE INTRODUCTION
HANDRAIL & BALUSTRADE INTRODUCTION
www.laidlaw.net
Handrails Handrails offer support on staircases, protection from falling and are a welcome support in case of sudden tiredness. They are required on both sides of a staircase. They should continue uninterrupted around half-landings to provide continued support for the elderly and ambulant disabled. This also provides safety and comfort for visually impaired and blind people by serving to guide them around the landing. Handrails should always extend at least 300mm from the top and bottom of a staircase to provide a ‘lead-in’ - which avoids unsteady persons from having to overreach in order to grasp the rail, and ‘lead-off’ - which allows them to be supported by the rail beyond the last step. The handrail should be fixed at a height of 900mm. However, a lower rail should be present in buildings frequented by children. If a higher rail is required - to prevent falls, for example - then a secondary rail should be available at the ergonomic height of 600mm. Handrails must also be suitable for use by people who are physically weak and have a poor grip. The best shape of handrail is circular in cross section, such that a hand can encircle it. The recommended diameter is 32 - 45mm (BS 8300). The elderly, in particular, suffer from a weak grip and a round profile is helpful. The handrail must be mounted at a sufficient distance from the wall such that a hand can travel along it without encountering the fixing brackets. The partially sighted will find the handrail more easily if it contrasts visually with its background i.e. the wall. Colour is an ideal way of helping to achieve such a contrast.

HANDRAIL & BALUSTRADE INTRODUCTION
HANDRAIL & BALUSTRADE INTRODUCTION
www.laidlaw.net
Balustrades Balustrades, essentially are freestanding barriers supporting a handrail and are composed of a top rail (handrail), a bottom rail (optional), upright supports which are fixed in a variety of ways to the floor structure and infill material of some kind providing the barrier to prevent falls. Typically, a balustrade is required on the open side of a staircase and surrounding any open balcony, gallery or atrium. The Laidlaw portfolio of Handrail & Balustrade systems is a comprehensive collection of individual system components which can be used to create matching handrails and balustrades offering specifiers a wide choice, to suit either performance and/or aesthetic requirements. The basic systems Laidlaw offers seven fundamental handrail and balustrade systems: • Nylon – using 4mm thick nylon-sleeved galvanised steel components • Stainless steel – using all stainless steel components • T imber & Stainless steel – a combination of a stainless steel support structure and solid timber rails. Also available with Nylon support structure. • N ylon & Stainless steel – a combination of a stainless steel support structure and Nylon sleeved handrail components • Structural Glass - a system of balustrading which utilises the structural properties of glass combined with Stainless steel or Timber handrailing • 3 kN System– using larger diameter stainless steel uprights to resist the greater loadings required for certain buildings, e.g. assembly buildings. • Modu-Line - a highly flexible, component based system which can be supplied as factory assembled elements or can even be assembled on-site. The design detail enables a high level of adjustability to suit site variations
Tactile Indicators Although not included in Building Regulation guidance, tactile indicators can help to make a building more ‘inclusive’. When incorporated into handrails, they can indicate to a visually impaired person the presence of the first and last riser on a staircase as well as floor levels. Braille indicators can also be included to highlight a floor number. Different types of indicator are available, as projecting buttons, rings or grooves.

NY HANDRAIL - GENERAL OVERVIEW Handrails NY.Type (NYLON LINE) The Laidlaw Nylon range is designed to bring together the structural strength and non-corrosive nature of a galvanised steel core with the pleasant feel and permanent colour of a thick nylon sleeve. It is one of the most effective ways of complying with all aspects of the guidance in Approved Document M (2004). Handrail construction is a fully galvanised tubular steel core with a solid nylon sleeve 40mm diameter with a 4mm wall thickness. Wall fixing brackets options are available with straight supports and 90째 bends (see page 17). Handrail ends can be straight with flat end cover cap, with a 90째 bend return to the wall with flat end cover cap or with a 90째 bend return connected to the wall with or without rose fixing (see page 17 for full details). The handrail is supplied pre-assembled, including all corner pieces, connection elements, screws and fixings. For colour please see colour chart, page 63. Also available with optional tactile elements. The method of calculating handrail lengths is shown on page 77.

Balustrades NY.Type (NYLON LINE) Rails, uprights and bottom rails are constructed using fully galvanised tubular steel core with a solid nylon sleeve 40mm diameter with 4mm wall thickness. The quality and dimensions of the steel meet the design requirements of BS 6180 and BS 6399. There is a continuous steel reinforcement in the connections and bends. Balustrades can be constructed with bottom rails and midrails or with 4 infill holders (see pages 23 to 25) for each railing section and suitable infill material. Infill holders are made of nylon with a metal core for drilling or clamping the infill sections. Handrails and infill panels can be produced ‘in-line’ with the support uprights or ‘offset’. We can also supply 5mm steel tension cables to order for fitting to predrilled uprights. Upright spacing approx. 1300mm, available with anchor fixing, bolt-through, side fixing or with welded colour-coated steel plate (118mm diameter, or 100mm square). Railing height 900mm to 1100mm (max). Other centres and heights are available as required to meet site conditions. The balustrading is supplied pre-assembled. No on-site manufacturing necessary. For colour please see Laidlaw colour chart, page 63. Available with tactile elements. The method of calculating handrail lengths is shown on page 77.

WS HANDRAIL - GENERAL OVERVIEW
Handrails WS.Type (TIMBER LINE) The Laidlaw Timber handrail and balustrade system provides the specifier with the ideal blend of traditional and modern styles. It combines the modern lines of stainless steel or nylon uprights, bends and brackets with the gentle warmth and natural feel of a timber rail which is not cold to the touch. Timber Line systems are characterised by the use of stainless steel components with timber or nylon components. The straight handrail sections are 40mm diameter solid beech as standard (alternative materials available to order - ash, oak, maple). All handrails are A-grade material without red core, steamed and kiln dried, with a clear polyurethane surface finish. Wall fixing brackets options are available with straight supports, or 90째 bends connected to a stainless steel tubular connecting piece with a brushed satin finish. Handrail ends can be straight with flat end cover cap, with a 90째 bend return to the wall with flat end cover cap or with a 90째 bend return connected to the wall with or without rose fixing (see page 29 for full details). The handrail is supplied pre-assembled, including all corner pieces, connection elements, screws and fixings. In addition to the stainless steel support brackets and rail ends, these are also available in nylon. Also available with optional tactile elements. The method of calculating handrail lengths is shown on page 77.
In addition to the combination of Timber and Stainless steel, the Timber handrail can be combined with nylon support components creating a completely different look.

STRUCTURAL GLAZING SYSTEM
STRUCTURAL GLAZING SYSTEM
www.laidlaw.net
Laidlaw’s structural glass balustrade system is based on the concept of a free-standing balustrade, which does not require separate uprights and infill panels. There are no gaps through which a child could squeeze, nor can it be easily climbed.
The glass balustrade For this system, the toughened glass balustrade is the structural element that supports the top rail, which can be of solid timber or stainless steel with a satin brushed finish. In each case, the top rail has a groove into which the glass balustrade is glued. In order to accommodate the groove, the diameter of the top rail is 50mm. At the base, the glass is clamped between steel sections, which are bolted to the floor structure following the principles set out in Annex B of BS 6180 on free-standing toughened glass balustrades. Available timbers are as for the Laidlaw Timber system, namely Beech, European Ash, American Oak or Maple, with an additional option of Walnut where the total run of top rail is greater than 100m.
Structural stability The system can be designed to meet even the most demanding horizontal U.D. line loading requirements set out in Table 4 of BS 6399-1 (see page 76). The horizontal load capability depends on the thickness of the glass, for example: Horizontal line load requirement [kN/m] Minimum glass pane thickness [mm]

Durability The Laidlaw structural glass balustrade system is suitable for both internal and external use. Touch characteristics Although stainless steel has a greater durability than timber when used externally, the timber alternative would feel less cold to touch in very cold winter conditions. According to clause 5.10.1 of BS 8300, wood handrails are preferred in these circumstances (see page 76). Visual clarity A key issue for people with impaired vision is the appreciation of the borders of the space through which they need to walk. On the access routes of public buildings, therefore, the use of tinted glass or manifestation on balustrades will give visually impaired people a greater feeling of security. As with traditional glass infill panels, the structural toughened glass can be tinted grey, bronze, green or blue, or receive manifestation in the form of acid etching or an applied emblem or logo. Health and safety In buildings likely to be used by children, safety on staircases and landings is paramount. Approved Document K includes guidance designed to minimise the risk that small children will become trapped, for example between the bars of the balustrade, or will have a serious accident as a result of climbing the balustrade. The fact that the Laidlaw structural glass system has no gaps and is extremely difficult to climb is a major benefit. Anti-ligature The structural glass balustrade is particularly suitable for buildings where it is necessary to avoid all likely ligature points, e.g. for prisons and mental health institutions, in which the Laidlaw range of Anti-ligature architectural ironmongery is appropriate.

MODU-LINE - THE INTELLIGENT MODULAR SYSTEM Modu-Line is an attractive, highly detailed and individual railing system in high grade stainless steel with a satin brushed finish. This system creates a unique constructional appearance which is complementary to modern building styles. This highly flexible system was developed in co-ordination with building specialists and perfected by means of a comprehensive programme of tests and trial prototypes. Modu-Line is designed to provide functionality and modern design easily and quickly, whilst meeting all the technical requirements for construction of a quality handrail and balustrade systems. Modu-Line offers a wide selection of visual variation, with either central or offset top rails available in nylon, stainless steel or a selection of solid timber. Not only can Modu-Line be factory prepared in the same way as our other handrail and balustrade systems, but it can also be ordered as ‘off-the-shelf’ components if required and assembled on-site. This is particularly beneficial for situations where there are short lead times or tight deadlines to meet.

Where the standard range of timbers within the Timber Line system (see opposite) do not provide a sufficient match with other timbers in an interior, Laidlaw offers a Walnut timber option. This option, and others, are available where the required quantity of handrail and balustrade top rail is more than 100 metre run in total.
One-piece timber rails If required, Laidlaw can supply one-piece timber top rails for the balustrades of the main stair flights, avoiding the need for stainless steel or nylon ‘T’ connections to uprights. The staircase opposite shows a one piece handrail fixed to the wall and a one piece handrail used on the balustrade assembly.

Types of infill Balustrade infill is available in three basic forms: • Bottom rails and Midrails • Solid infill panels, using a variety of materials • Tension cables Infill panels The most common infill material is glass. It maintains an open character and helps to maximise the amount of light which falls onto the staircase. However, in some circumstances a more enclosed feel is required and several forms of solid infill panels are available including perforated metal sheet and solid laminate which gives possibilities of colour and finish combinations to be achieved.
Tension wires used as balustrade infill will need local planning consent
Glass infill panels Glass infill panels are the most popular, as they can be used for all the Laidlaw balustrade systems and they allow natural daylight to flood the stairwell. When used in conjunction with ‘screw-stud’ panel holders, glass panels can be provided in lengths up to 3.5m. For normal applications, the glass is toughened to European standard EN 12150 to resist impact, although a bomb-proof film can be applied to the glass, if required.

Various tinted glass options can be provided. A simple tint can often be sufficient to ensure that the boundaries of a stair or landing are recognised by a person with impaired vision, giving them a feeling of greater security. BLUE

Manifestation on glass Manifestation refers to markings on clear glass doors, screens and other large glazed areas to ensure that people are aware of the presence of the glass surface. It is particularly useful for visually impaired people who may not otherwise notice the barrier sufficiently quickly to avoid an accident. There is nothing in the Building Regulation Approved Documents requiring manifestation on balustrade infill panels. However, like tinted glass, it is a way of helping visually impaired people, while turning a plain glass infill panel into an attractive design feature. Options for manifestation include designs, company logos, or other emblems created by: • acid-etching of the glass surface • surface application of weatherproof markings (decals).
Infill extended below the stair pitch line Where there is no solid string to the stair on the stair well side, there is the possibility that the open triangle would allow a sphere of 100mm diameter to pass through (see the guidance in Approved Document K to the Building Regulations for England and Wales). To avoid this, Laidlaw can provide a balustrade infill, that extends below the pitch line of the stair to block this potentially unsafe gap.

I have used Laidlaw on a number of occasions and they never fail to deliver. When you put an order in with Laidlaw, you can rely on them fabricating and installing the railing systems within the timescales you specify – and they’re very often up against tight deadlines. Adrian Ward, Project Manager at The Austin Co
The use of Laidlaw systems In a new build facility on the Astra Zeneca Macclesfield site, Laidlaw won the contract to supply handrail and balustrade systems for four staircases. As three of the four staircases are within an area devoted to highly-sensitive scientific activities, Laidlaw’s Nylon system was specified. Nylon is the ideal material to use for handrails and balustrades in this environment as it is resistant to scratching and can easily be cleaned, reducing the risk of germ build-up. The fourth staircase, which serves the administration areas, uses the Laidlaw Timber system in oak, with stainless steel bends. Infill panels of 10mm clear toughened glass were chosen for all four staircases

Tessa Clark, Head of Store Design, Marks & Spencer
Europe’s biggest retail outlet, the recently opened £1.6 billion, 42-acre, 300-store Westfield-London Shopping Centre in White City saw several leading retailers use Laidlaw handrail and balustrade systems, doorsets and ironmongery . These included the prestigious Marks and Spencer, House of Fraser, Boots and FCUK outlets. The M&S design style required a greater sense of open space. Laidlaw’s Square Top Handrail System with Structural Glass was therefore used around all escalator areas at the 103,000 square foot, 3-floor flagship store. The free-standing balustrade requires no separate uprights and there are no gaps through which a child might squeeze. The toughened glass structural balustrade supports a 50mm top rail with a groove cut into it to enable the components to be fully adhered to one another. At the base, the glass is clamped between steel sections which are bolted to the floor structure.

The use of Laidlaw systems The requirement was for a handrail and balustrade system that could withstand heavy use by customers to the store, but was easy and quick to install. Laidlaw were successful in winning the contract to supply and install the new system principally because their 3kN system had been developed specifically to meet this requirement. It is a component-based system, manufactured to meet the heavier horizontal loading standards of BS 6399 for buildings where the general public potentially congregate in large numbers.

The use of Laidlaw systems Trinity & All Saints College is a higher education college, accredited by the University of Leeds, with an excellent reputation for undergraduate and postgraduate courses. Laidlaw’s Nylon railing system was the perfect choice when they refurbished the main part of the college, including 26 staircases. Conscious of the guidance in Approved Document M that handrails and balustrades should contrast with any background, navy blue nylon-sleeved steel top rails and uprights were chosen with 10mm clear glass infill panels. It was because Laidlaw offer a choice of 12 colours for the nylon sleeve that Trinity & All Saints College was able to select an option that complemented its corporate colours.
Detail of nylon system with glass infill
Great care was taken to ensure that the detailing of the handrails and balustrades was in line with AD M guidelines. In particular, handrails and balustrades followed the key heights above the pitch line and landings, and the connection of the uprights to the top rail from the underside ensured that grip was uninterrupted along the rail.

The use of Laidlaw systems Hellesdon is the headquarters of the East Anglian Ambulance NHS Trust, which covers the counties of Cambridgeshire, Norfolk and Suffolk. Since the Trust is defined as a ‘service provider’ under Part lll of the Disability Discrimination Act (DDA), it is their duty to make reasonable adjustments to ensure that disabled members of the public are not discriminated against because of their disability. In this case, the Trust decided that they needed to install a ramped access, in addition to the steps already provided and, because the ramp needed to be more than 2m long, they followed the recommendations in BS 8300 that there should be a handrail on both sides. Also, even though there is no requirement for guarding under Part K of the Building Regulations, the Trust wanted to provide protection so that wheelchair users could not inadvertently roll under the ramp’s handrail. Laidlaw’s Combi system, with nylon-sleeved steel balustrade top rails and stainless steel uprights, was selected for the refurbishment on the basis that the nylon gave a hand hold that was not cold to touch, yet the stainless steel was compatible with the design of the rest of the building. For the ramp access, a balustrade infill of stainless steel strained wire was selected to minimise the visual impact and a lower rail of stainless steel was used as a physical barrier to wheelchairs at ground level. The guarding, which runs from the end of the ramp access to the entrance of the building is at a higher level and includes glass infill panels. These are etched with manifestation (the name and badge of the ambulance service) to make the presence of the barrier apparent to visually impaired people leaving the building.

LEGISLATION, REGULATIONS & STANDARDS
www.laidlaw.net
Laidlaw technical advisors are able to advise on legislation currently in force, in particular on how to meet Building Regulation requirements and how to design handrails and balustrades to accommodate disabled people and avoid the risk of litigation under the DDA.
Building regulations England and Wales – Approved Document M (2004) – Access to and use of buildings The 2004 edition of Approved Document M includes updated sections for non-domestic buildings. The main requirement no longer makes specific reference to disabled people, but requires that reasonable provision is made to ensure that buildings are accessible and usable. The aim is to make buildings more ‘inclusive’ by satisfying the needs of all users, regardless of disability, age or gender. Jubilee Public Library, Brighton • P rime Minister’s Better Public Building Award • PFI Award: Operational Project with Best Design • Regional RIBA Award: Best Designed Public Building in the South East • Sussex Heritage Awards: The Community Award • Building Services Awards: Major Building of the Year 2005 • CIBSE: Major Project of the Year 2005.
Part M applies not only to new developments, but also to existing buildings that are subject to alterations, extensions and changes of use. In respect of handrails (and by implication balustrade top rails), the guidance in Approved Document M relates to: • The size, profile, spacing and termination of handrails. • The location and extent of handrails on steps, ramps and landings. • The surface characteristics of handrails in relation to grip, touch and visual contrast. In order to reconcile some of the differences between the 2001 edition of BS 8300 and the 2004 version of Approved Document M, a number of key issues that concerned the construction industry were reviewed and incorporated in an amendment to BS 8300 in 2005 (see page 57). As a result, The ODPM have made available a web page of FAQs, which explains that, in respect of these key issues, the recommendations in the amendment to BS 8300 can be considered an acceptable, and more up-todate, alternative to the guidance in Approved Document M (2004). The FAQs can be found in the Building Regulations area of the ODPM web site. England and Wales – Approved Document K (amended 2000) – Protection from falling, collision and impact Guidance in AD K indicates that the top rail of balustrades should be no lower than 1100mm for the edges of landings and balconies. In addition, measures are included to prevent the head of a child under 5 years of age becoming trapped through the guarding.
For buildings likely to be used by children under 5, a 100mm sphere should not be able to pass through any opening in the guarding and children should not readily be able to climb the guarding. In addition, another FAQ on the ODPM web site indicates that, subject to approval by Building Control, a triangular opening between the guarding, the tread and the riser is acceptable, provided that the bottom of the guarding is not more than 50mm above the pitch line (measured perpendicular to the pitch line). Scotland – Non-domestic Technical Handbook – Section 4 – Safety Guidance on meeting the functional requirements in the Building (Scotland) regulations 2004 is set out in Technical Handbooks, one for domestic and the other for nondomestic buildings. All guidance that was previously in Part S of the Technical Standards is now distributed throughout the Technical Handbooks, although many of the issues relating to accessibility are in Section 4 of the non-domestic volume. In relation to handrails and balustrades, Section 4.3 deals with stairs and ramps and Section 4.4, pedestrian protective barriers. The relevant heights of handrails shown in the Technical Handbook are shown in the diagram below, but there is no guidance on the size and profile of any handrail, nor its spacing from an enclosing wall. Northern Ireland – Part R (2000) – Access and facilities for disabled people Guidance on meeting the requirements of the Building Regulations (Northern Ireland) 2000 is currently as the 1999 edition of Approved Document M for England and Wales, except that the diameter of the circular handrail is shown as between 38 and 50mm. However, consultation on an updated version of the Technical Handbook is now concluded and the revised edition is likely to be published later in 2006. This will generally reflect the guidance in the 2004 edition of Approved Document M, but is likely to follow the most recent recommendations of the 2005 amendment of BS 8300.

The DDA The Disability Discrimination Act 1995 (DDA)
Visual contrast
The Disability Discrimination Act is human rights legislation, which imposes a duty on employers (under Part ll) and people or organisations that provide a service to the public (under Part lll), not to discriminate on grounds of disability. For education buildings, the Special Educational Needs and Disability Act 2001(SENDA) imposes a similar duty on establishments providing educational services.
A person’s perception of visual contrast between two surfaces appears to be strongly correlated with the difference in the amount of light reflected from their surfaces, i.e. their light reflectance values (LRVs). In theory, a perfect white has an LRV of 100 and jet black, 0, but these values are never achieved in practice.
A building, or a design solution, cannot be DDA-compliant. It can only be designed or built in a way that helps people meet their duties in the Act and, therefore, minimise the risk of a legal challenge. For many existing buildings, it will be necessary to make ‘reasonable adjustments’ to certain ‘physical features’, e.g. to widen a doorway or to modify a staircase, where otherwise it would impossible or unreasonably difficult to accommodate a disabled person. Since any alterations to a building need to comply with building regulations, the guidance in Approved Document M, Section 4 of the Scottish Technical Handbook and Part R of the Northern Ireland regulations will be the first reference point for suitable design solutions. However, for issues that are not covered in the regulations, the recommendations in the most recent edition of BS 8300 should be followed. British Standards BS 8300: 2009 Design of buildings and their approaches to meet the needs of disabled people – Code of Practice BS 8300 provides good practice recommendations on the design of buildings so that they are convenient for use by disabled people. It is widely used as a reference document for guidance on issues not specifically covered in building regulations. The Standard, first introduced in 2001 has now undergone a complete review incorporating research by BRE into accidents on steps and stairs. The issues contained within the revised standard for handrails and balustrades are: • The dimensions for circular handrails and their spacing from an enclosing wall. • The definition of ‘visual contrast’ in relation to ‘light reflectance values’ (LRVs). • The application of ‘not cold to the touch’. Handrail dimensions In the 2009 review of BS 8300, convergence has been achieved with BS 5395 Pt1 with the emphasis being placed on achieving a ‘power grip’ to reduce the incidence of falls on stairs. The optimum external perimeter of the handrail is established at 100 - 140mm, giving a corresponding diameter for a circular handrail of 32 - 45mm (previously 40 - 50mm).
Whereas AD M (2004) gives a rigid definition of visual contrast (where there is a 30 point difference in LRV), the 2005 amendment to BS 8300 recognises that visual perception is affected by the relative area of surfaces and whether they are textured, curved, metallic or glossy. The latest guidance is that, although a difference in LRV of 30 points is a reliable indicator of visual contrast, there is anecdotal evidence that a difference of about 20 points may still be acceptable. Differences in LRV are most important between small and large areas, e.g. a lever handle and a door, than between large areas, such as walls and floors. High gloss should be avoided for doors and elements with a larger surface area. Not cold to the touch It has been a long standing recommendation within BS 8300 that handrails used externally should not be ‘cold to the touch’. This aspect was supported in the 2005 revision to the standard stating that external metal handrails can become extremely cold and uncomfortable to hold and therefore represent a safety hazard. To minimise these effects, metal handrails having a coating material with a low thermal conductivity such as plastics were preferred. However, the 2009 review recognised the need to resist vandalism and misuse. Whilst the avoidance of discomfort from excessive heat or cold remains an essential recommendation within BS 8300, the use of stainless steel handrails externally is now considered acceptable due to its comparatively low thermal conductivity and the need to address the issues of vandalism and misuse. BS 6399 Loadings for buildings – Part 1: Code of practice for dead and imposed loads This is the standard referred to in Approved Document K for details of the horizontal forces that barriers should be capable of resisting. In the standard, Table 4 gives the ‘characteristic’ design loads on parapets, barriers and balustrades (see simplified table below, based on Table 4). BS 6180 – Barriers in and about buildings – Code of practice This British Standard reiterates the minimum barrier height for guarding of 1100mm in Approved Document K. It also gives specific recommendations for barriers of concrete, glass, metals, plastics and timber, as well as generic site fixing details.
The spacing from an enclosing wall has also been increased in line with AD M and is now recommended as 60 - 75mm.
NB: The horizontal uniformly distributed line load should be assumed to act at a height of 1100mm above the floor or pitch line, irrespective of the height of the actual barrier. The three load types are not additive, but need to be treated as three separate load cases.

Caluclating Handrail Lengths When specifying the length of a Laidlaw handrail or to determine a length of run of handrail the following principles apply: 1. In all instances the longest length is taken including handrails which are angled or splayed 2. At bends the outer angled length is taken 3. Rail lengths shown are

The benefits of Laidlaw’s component-based system • Having a stock of key components ensures quick delivery and the fact that the majority of the assembly is carried out in the factory ensures a speedy installation once on site. • The finished product is aesthetically superior to one that is made up on site because there are no unsightly welds, no sharp edges or angles, no deformation of bends and no grinding is necessary. • A consistent finish is obtained within an individual installation and the same appearance is guaranteed in projects throughout the UK. • The top rail and infill panels are demountable, making it easy to repair the balustrade without damaging the surroundings. • The installation is sustainable as, at the end of the life of the building, all components are recyclable.

GUIDE TO INSTALLATION
www.laidlaw.net
Installation Laidlaw offers a complete design, supply and installation service for their factory-assembled handrail and balustrade systems. Installation is the final stage in the process and, by adopting the best principles of supply chain management and using specialist fixing teams, Laidlaw ensures that the final installation is in strict accordance with the original design.
All installations are built to order based on the original site measurements taken by our survey team, or from architects’ drawings. Following the preparation and client approval of Laidlaw’s production drawings, the handrails and balustrades are fabricated to the agreed measurements, using stock components.
Checking the top rail is level before tightening the fixings.
To minimise on-site work, as many components as possible are assembled in the factory and supplied individually packed and wrapped to site to avoid damage. This method ensures that no cutting, bending or measurement of handrails and the balustrade structure is required on site. This means that there is less on-site assembly and overall installation time is reduced. Once the uprights and rails are in place, checks are made to ensure that line and level are correct before finally securing the uprights. Uprights, connectors and infill panel holders are secured using an Allen Key, with the screw head tucked into the upright to ensure a smooth, hidden connection. A protective covering is left on the handrails to provide protection against damage if other building work is being carried out in the building. When the balustrade uprights and top rails are fixed, infill panel templates are produced to ensure that the panels are manufactured to accurate sizes. The panels are produced offsite, then brought to site to be fitted into the balustrade quickly and easily using the clamps previously fixed to the uprights. Alternatively, panels can be made available for installation at the same time as the balustrade rail components, saving time in the overall programme. ‘In-line’ infill panels are secured with 4 clamps, top and bottom, each side; ‘offset’ infill panels, by ‘screw-stud’ panel holders, top and bottom.
Connecting the uprights, top rails and infill panel holders using an Allen Key.
When all is complete and no further damage is likely to occur, the protective covering on the handrails and balustrade is removed.
Fixing an in-line glass infill panel to the four ‘clamp’ type panel holders – note protection to top rail.
