GUIDANCE Doc – BS8300 and Bldg Regs Approved Doc Part M
BS8300 Design of Buildings and their Approaches to meet the needs of Disabled Persons
BS8300 2009 is a fully revised version of the Code of Practice and includes updates to Building Regulations Approved Document M – Access to and Use of Buildings which contained conflicting guidance, most notably concerning opening forces and visual contrast.
Building Regs – Approved Part M Doc 2010. “Access to and use of buildings”
There is a requirement that the opening force at the leading edge of the door must not exceed 30N between 0º and 30º from closed and 22.5N thence until 60º. The options available to meet this requirement are varied and it may prove beneficial to discuss the project requirements prior to finalising the optimum solution – locality and building design can impact on performance levels, so no single proposal will meet all demands.
- Our standard manual Door Closers are fully compliant. NOTE Concealed Door Closers generally do not offer adjustment and thereby often do not comply with this requirement..
- However, in instances, the above closers may not be strong enough to close the door during windy conditions.
- Therefore the use of a Low Energy Power Assisted Operator may be recommended. NOTE:- This should not only “power open” but “power shut” to ensure building security in similar windy conditions. We only use proven Power Assist Operators which offer both functions
- BS 8300 – 6.3.2 states: “ Where (the force of) the door closing device is in-sufficient to keep an entrance door closed under windy conditions, consideration should be given to installing one of the following door closing systems:
- a. a power operated (automatic) door (can be fob or transmitter operated for wheelchair users etc)
- b. a low energy swing door (assists manual opening)
- c. a power operated revolving door arrangement;
- d. an entrance lobby or air lock system of inner and outer doors”
Swing-action entrance doors which are required to be fully accessible but may not be suited to full automation, are best equipped with power assisted, low-energy operators. These are commonly available as electromechanical devices (although pneumatic operators are also available for specific, demanding applications)
BS 8300 – 6.3.4 states:
- “A low energy power operated door operator should be considered for use on swing doors as these doors can either work in manual mode or be set to provide powered opening assistance to users when required, either in ‘push-and-go’ or ‘power-assist’ modes. After a hold-open period, the swing door self closes in the same way as a conventional door closer”.
- Note 1: The ‘Push-and-Go’ feature activates when the door is pushed beyond 25mm.
- Note 2: Guidance on the safe use of low energy swing doors is given in BS 7036-4
This project called for the removal of the existing Main Entrance doorset and incorporation of an automatic opening doorset for wheelchair and electric chair usage into the existing frontage. The door design and dimensions were also amended to meet current DDA guidelines.
Solution:- Protect-AP Doorset designed to colour match upvc windows and structural steel framing complete with automatic opening facility with integral safety sensor
