Entrance flooring systems

BS 7953:1999 pdf free.Entrance flooring systems — Selection, installation and maintenance.
5.2 Surface materials
A wide variety of surface materials can be used separately or in various combinations. These include, bUt are not restzicte(l to: natural fthres Such as wool, cotton, and coir (coconut matting); man-made fibres such as polyaniide (nylon), polypropylene, viscose uuI polyester; and other materials such as natural and synthetic rubber, paper, polyvinyl chloride and other plastics.
5.3 Backing materials
As with surface materials there are numerous options, although in sonic cases the entrance flooring system material may be reversible. The backing materials include, but are not restricted to: synthetic and natural rubber, polyvinyl chloride, polyurethane and bitumen.
5.4 Retaining systems
The retaining systems may be recessed or surface
mounted.
5.5 Performance testing
Currently there are no agreed comparative test methods for the assessment of soil removal and retention for entrance flooring systems.
6 Design considerations
6.1 Ease of access
For an entrance flooring system installed in a new building or in a new extension to an existing l)ullding the design of 11w entrance should meet the requirements of Approved Document M of the Building Regulations 1991 (England and Wales) 11], Part T of the Building Standards (Scotland) Regulations 1990 121 or Part R of the Building Regulations (Northern Ireland) 1994 131.
An entrance flooring system ShOUl(1 not rntio(IUCC any features which make access more difficult. Consideration should he given to users of wheelchairs, sticks or crutches. The system should be designed without abrupt changes in level which could result in tripping accidents or impede wheeled traffic.
6.2 Effective length
The objective with any entrance flooring system is to achieve the maximum number of footfalls within the space available. This can he a prol)lem as (lesigi) parameters often result in areas which are too small for a conventional system to provide effective control of soil. This can require the use of an external system. In any case consideration should be gven to such factors as external and internal conditions, traffic levels, size of entrance, use of building and type of internal for coverings.
6.3 Traffic patterns
The entrance flooring system should cover the actual routes of people entering the building. Modifications to the site layout should be considered in order to maximize the number of footfalls on (he entrance flooring system whilst ensuring ease of access.
6.4 Cleaning
Careful consideration should be given to the most appropriate cleaning method(s) for the materials to be used and whether there is adequate cleaning equipment and staff to carry out the work. The higher the level of traffic, the more demands are put on the entrance flooring system and its cleaning requirements, to ensure the product’s effectiveness and aesthetic acceptal)illty.
6.5 Electrical power points
It is important to ensure that there are convenient electrical power points to carry out the proposed cleaning routine of the entrance flooring system.
6.6 Appearance
Entrance flooring system materials are available in a wide range of colours and textures; logos can also be incorporated. Entrance flooring systems can enhance the area aesthetically as well as giving a cleaner, safer indoor environment. Any visual finish should be designed so as not to confuse e.g. a floor surface which looks like a step or steps should be avoided.
6.7 Fire safety
The fire properties of floor surfaces are not controlled by any national building regulations but local regulations may restrict their use in primary escape routes and certain constructions and transport regulations may restrict their use in vehicles. Reference should be made to DD 240,which gives guidance on the development of fire safety systems for the construction industry.
7 Pre-installation recommendations
7.1 General
There should be consultation between all parties cOII((fl1e(l wit Li the installation, beginning at an early stage and continuing through to completion. Consideration should also be given to co-operation with contractors for the installation of the intenor floors (see BS 5325 and uS 8203). Information to be exchanged should include that listed in 7.2. as applicable. However, as each project is unique, other aspects not listed may need to be discussed.
7.2 Specifications
The completed drawings and specifications should provide comprehensive information on:
a) size and shape of proposed entrance flooring system;
b) type of sub-floor construction; c) particulars of any under floor services;
d) concrete ba.se or screed curing and drying time required before installing the entrance flooring system;
e) screed or base with finished floor level, jwrnussible deviations from datum and degree of surface regularity;
1) type of damp—proof menhl)rane and its hwation within the floor construction;
g) choice of adhesives and accessories; Ii) direction of traffic;
i) skirtings and abutments;
j) ducts;
k) junctions with other adjacent floorings;
I) if a recessed well exists, dinwusions including depth to assess suitability for the proposed product;
8 Supply and installation
8.1 Site information
Details that should be considered include:
a) location;
b) ease of access;
c) whether any other work is being carried out at the same time;
d) storage facilities;
e) heating, lighting and power supply and any additional items considered necessary to expedite the work;
f) the number and function of other contractors on
site;
g) the availability of hoists and lifts and their
maximum capacity;
h) floor loading capacity;
i) security arrangements.
8.2 Contract conditions
Contract conditions should include:
a) particulars of the form and type of contract;
b) whether the work is to be completed in any specific order or in sections;
c) safeguarding against damage and theft;
d) health and safety provisions;
e) welfare facilities;
f) insurance;
g) timing and access agreements.
8.3 Testing
Details of any conformity testing of the base, screed and associated support should be provided.
BS 8204-1 gives detailed information on the preparation of screeds, and the general precautions necessary to provide a satisfactory sub-floor and eliminate construction moisture are given in BS 5325 and BS 8203.
8.4 Post-installation check
The entrance flooring system should be installed according to the manufacturer’s recommendations and in accordance with the agreed specification for the work.
9 Cleaning
9.1 It is of vital importance to the satisfactory performance of any entrance flooring system that a thorough cleaning routine is carried out. A WeIl—cleane(l system will remove and retain soil. If cleaning is inadequate the entrance flooring will l)econ’Ie saturated with soil and l)econle a source of soil which is transferred into the building.
9.2 The customer should he left with full details of the cleaning required to enable the entrance flooring system to perform satisfactorily in use. The reconunendat ions should include (letallS of the various met hO(IS of cleaning re(luire(l and the time scales at which they ShoUl(l be carried out. Such instructions should be in clear, written form and cover the reconuuende(l cleaning flWt.hO(IS appropriate for all the types of entrance flooring SySteflis in.st.aI led.BS 7953 pdf free download.Entrance flooring systems
