BISoN ThE BENEFITS
RAPID CoNSTRuCTIoNBison precast staircases are delivered to site ready for
installation and can speed up construction schedules to
provide safe and immediate routes between floors under
construction. Once hoisted into place, the precast stair
flight is suitably protected and ready for use.
PRoVEN QuALITY AT ECoNoMIC CoSTExceptional quality is built into each precast stair structure
to ensure the most appropriate, efficient and cost-effective
product solution. Precast stairs reduce the requirement for
complex on-site shuttering and minimise the risk of delays
that can occur with site-poured concrete.
STANDARD MouLDS wITh VERSATILE DESIGNManufactured in precision steel, the precast stair moulds
offer any riser height, combined with a range of tread
dimensions to provide a customised stair design from
standard moulds.
EASE oF INSTALLATIoNBison’s lifting pins are cast into the precast concrete during
manufacture in the factory, making on-site installation safer,
easier and quicker.

DIMENSIoNAL REQuIREMENTS
The dimensional requirements for all staircases are set out in the Building Regulations Approved Document K. The Building
Regulations require that flights of stairs should have all the same rise and going within the dimensional requirements shown below.
The requirements for the three categories of stair considered in the Building Regulations Approved Document K and that for
disabled people in Approved Document M are as follows:
hEADRooM
Bison precast staircases conform to all current regulations and can accommodate most architectural layouts. Design and
manufacture is carried out in accordance with BS 8110: 1997.
Generally stairs are cast in engineered steel moulds giving a Type ‘A’ finish*. Landings can be cast integral with the stair
flights or separate in order to achieve the optimum staircase construction.
When balustrades are required, it is recommended that fixings for these are drilled on site. A minimum of 50mm should be
allowed between the edge of the concrete and the edge of any pocket or fixing.
Bison are specialists in staircase design and you are invited to discuss requirements with us so that the most efficient and
economic staircase design can be achieved.

1.0 SCoPE oF ThE SPECIFICATIoN
1.01 Relates to: This specification covers the design, manufacture
and associated site work of the following types of stairs:-
• ReinforcedConcretestairs
1.02 Description of stairs
• Theprecaststairsaredesignedandmanufacturedas
reinforced precast stairs.
2.0 MATERIALS
2.01 Standards: All materials are to be in accordance with the
appropriate British Standard and this specification.
2.02 Concrete: The design strengths of concrete used in the
design and manufacture of Bison units is as follows:-
Reinforced Design
• UltimateConcreteStrengthisaminimumof50N/sq.mm.
2.03 Admixture: Concrete used is of a self compacting nature,
and therefore does contain some additives. This additive is
to provide adequate suspension in our mix to achieve the self
levelling nature of the concrete.
2.04 Reinforcement: Reinforcement for reinforced precast stairs
is generally high yield, high bond bars complying with the
requirements of BS 4449:2005 and is detailed in accordance
with BS 4466 unless specified.
3.0 DESIGN
3.01 Code: The design of Bison units is in accordance with the
requirements and recommendations of BS 8110:1997
“The Structural Use of Concrete”.
3.02 Service Class: The design of Bison reinforced concrete stair
units is to Serviceability classification, Class 3 with a limiting
crack width of 0.1mm, and RC stair units to 0.3mm crack
width.
3.03 Durability: The standard Bison stair is designed to comply
with the durability requirements of BS8500:2006.
3.04 Fire: Fire resistance is based upon the tabulated data
contained within BS 8110 : Part 2 Section 4. Sections are
available for fire periods of 1 hour or 2 hours without the
addition of further finishes. This period of fire resistance may
be further enhanced by the application of appropriate finishes.
3.05 Horizontal and Vertical Ties: Ties necessary to satisfy the
requirements for accidental damage should be specified
by the Engineer with the responsibility for the design of the
overall structure in accordance with the relevant Codes of
Practice. To accommodate tie details, a C40 structural topping
may be required in lieu of screed zones. To comply with class
2B structures and greater, generally stairs are tied at bearing
ends as per Bison standard details.
4.0 MANuFACTuRE
4.01 Method of Manufacture: Bison standard precast stairs are
manufactured in precision engineered steel moulds United
Kingdom patent numbers 2193922 and 2217359. Other stairs
to suit specialist requirements may be made using ramp
moulds with timber stringers and risers.
4.02 Mould: The design of the mould is such that any riser
height within the range of 150mm to 210mm is available.
Alternative tread dimensions of 250mm, 275mm and 305mm
are available. These are fixed dimensions, as is the angle
of the receding riser (all Bison standard moulds have a
nominal 25mm recede). Thus the going varies very slightly
with the riser dimension as shown in the table. To achieve
the economic benefits in offering Bison standard precast
staircases, it is assumed that minor modifications can be
made to the stairwell dimensions to accommodate the
standard units.
4.03 Dimensions: Bison Standard staircases may be manufactured
up to 2.40m wide. Special widths may be provided using ramp
moulds which are of timber manufacture. The maximum length
of the Bison standard staircase is 11.00m. However the length
of the stair may be restricted due to the weight considerations
during manufacture and this is set at maximum of 10 tonnes.
4.04 Permitted Deviations: Cross-sectional tolerances are within
the limits set out in clause 6.2.8.3 of BS 8110:1997. Erection
tolerances are as per BS5606.
4.05 Balustrade Fixings: It is recommended that these are
drilled on site by others to suit individual requirements. A
minimum dimension of 50mm, 75mm preferred, should
be allowed between the edge of a pocket of fixing and the
edge of the concrete and to a maximum depth of 100mm
4.06 Lifting points: These will be provided in the factory as
proprietary inserts to be made good on site by others.
4.07 Finishes: The Bison Standard staircase is cast on its
side, all surfaces with the exception of one string are from
an engineered steel mould face giving excellent quality.
Concrete surface finish to soffit, treads, riser and one
string is to a Type A finish (minimum)* as described in
clause 6.2.7.3 of BS8110:1997. The treads and risers are
suitable for the direct application of carpet or tiles or for a
screed finish applied with a suitable bonding agent.
4.08 Landings: Bison can supply flights with attached
landings and these must have a minimum of 50mm sand/
cement screed added so as to allow for manufacturing
tolerances. Due to this requirement, the top step contains
a recess thus creating a screed stop – see Bison general
arrangement drawings. Separate reinforced landings are
also available. These also are to be used in conjunction
with a screed again to allow for manufacturing tolerances
and to cover up the support angle cast in to the Bison
flights.
4.09 Angles: Purpose made angles may be provided at
the end of flights or stairs to bear onto other concrete
members such as landings or beams. The design of these
is subject to strict limits and may require that additional
support is provided.
5.0 SITE woRk
5.01 Standard: All site work is to be undertaken in accordance
with the best current practice and Health & Safety
legislation. For further advice reference should be made
to the “Code of Practice for the Safe Erection of Precast
Concrete Flooring”.
5.02 Bearings: Level and structurally adequate bearings for
Bison precast units are to be provided by others. These
should generally be 100mm for concrete and masonry
and a minimum of 75mm for steelwork, but subject to the
requirements of clause 5.2.3 of BS 8110:1997.
5.03 Temporary Bearings/Propping: Unless the design
specifically allows for units to seat onto temporary
bearings (i.e. head trees and bearers, etc.) this practice
shall be avoided wherever possible. In cases where such
measures are unavoidable, fixing must not progress until
permission has been obtained from a competent technical
authority within the Bison organisation. We shall specify
on our working drawings details and duration of any
temporary propping that may be required.
5.04 Holes and Cutouts: Small holes up to 60mm diameter
may be drilled on site. Larger holes may be cut subject to
the design capacity of the staircase.
5.05 Lifting sockets: All sockets formed for lifting purposes
are to be filled and made good by others, when erection
is complete.
5.05 Soffit fixings: Several fast and cost effective proprietary
systems are available for direct fixing to concrete and we
shall be pleased to offer recommendations on request.
6.0 QuALITY MANAGEMENT SYSTEM
6.01 QMS Reference: Bison are members of the BSI
Registered Firm Scheme for Quality Management Systems
to BS EN ISO 9001:2000 for the design, manufacture and
installation of precast products.
6.02 Scope: Membership of the scheme ensures that
all processes relevant to the design, manufacture
and installation of precast products, are subject to
independent review and approval by the British Standards
Institution.

TRAILASAFE®
Trailasafe® is designed to prevent or mitigate injuries
resulting from falls from trailer decks. Comprising
synthetic mesh suspended from a series of brackets
housing support arms, the system arrests the fall of
personnel, absorbing the energy of their descent and
ensuring their safety. Fully demountable, the system can
be stored within the vehicle or at the unloading point.
ThE BISoN AIR MATThe Bison Air Mat system has been tested by the BRE
and approved by the HSE. The Bison Air Mat system
comprises a series of interconnected and interlinked
mats available in a wide range of standard sizes. Using
a combination of modules they will accommodate
almost any floor area. Where the edges of an area to be
protected are open, or have large vertical voids that may
pose the hazard of “roll-off” fall to a lower area, special
parapet and corner mats can be provided.
hoLE CoVERSVoids such as service holes, formed in precast floor units
are trip hazards and have the potential to cause serious
injuries. Bison’s solution is the Hole Filler: a strong yet
slimlined product which is suitable for most holes.
The yellow, anti-slip cover is fully reusable and comes in
two sizes, 250mm or 350mm square. Each may be either
screwed down or fitted without the need for power tools,
by spreading the unit legs, locking it into position.
Health and Safety is a major concern for Bison, and we have developed a range of methods and systems which help to
ensure that anyone using Bison products can do so with minimal risk to themselves or others.

In use, Bison precast concrete offers thermal capacity which
can be used for active Fabric Energy Storage (FES), that
can reduce carbon emissions from a building by up to 50%
by reducing the need for air conditioning. Using FES makes
good long-term financial sense for occupants who benefit
from reduced energy bills.
PART A
The Building Regulations Part A, December 2004, introduced
a system of classification of buildings to reflect the risk of
disproportionate collapse probabilities. Bison’s in-house
experts can offer advice on the details required for each of
the main frame options related to reinforced concrete stairs.
PART k
Approved Document Part K of The Building Regulations
2000 calls for the protection of falls, collisions and
impacts of stairs, ladders and ramps, with particular

products. As market leaders in the precast concrete
industry, Bison has unrivalled experience in producing
both standard and bespoke products that work to deliver
the requirements of industry legislation.
Bison’s in-house design experts
