PRODUCT OVERVIEWBox CulvertsEasy to install, suitable for very shallow or deep fill, idealfor use in a wide variety of civil engineering applications
4
Hanson Building Products is thelargest producer of box culverts inthe UK, and are members of the Box Culvert Association.
Since its introduction over 45 years ago the range of box culverts we offerhas continued to expand.
Whilst offering increased flexibilityHanson Box Culverts retain all theiroriginal advantages.
They are easy to install and can bemade to suit very shallow or deep fill.
They also offer economy by beinguniquely designed for particular loading
conditions and are efficiently producedin standard sizes.
As these advantages have becomewidely recognised their range ofapplications has increased making themideal in a wide variety of civilengineering applications.
Hanson Box Culverts are available in
a range of 144 standard sizes from
1000mm x 600mm to 6000mm to
3600mm. Non-standard sizes and
internal profiles can also be readily
provided including shaped inverts,
dwf channels, and units with cross
over channels.
Reference to our table of standard
sizes will give the size necessary to
meet any conditions which may be
required in terms of storage volume,
flow capacity etc. For larger culvert
widths, twin or multiple sections may
also be considered.
Unlike pipes and corrugated steel
assemblies, box culverts can be
designed to carry vertical load without
the relieving effect of side pressure.
Therefore, when culverts are used in
multiple sections, they can be laid side
by side with only a nominal gap
between them.
By comparison with arched or circular
sections no flow area is lost through
either excessive spacing apart or
curved profiles.

DESIGN & SPECIFICATIONBox Culverts
Hydraulic designDischarge rates for box culverts in the
Hanson standard range are calculated
for a gradient of 1 in 1000 in
accordance with the Colebrook-White
equation assuming the culvert running
full under uniform flow conditions.
Comparable discharge rates for
circular pipes are given in the Table 2
(overleaf).
For any gradient between 1 in 1000
and 1 in 250, the gradient multiplier
(Table 3 overleaf) should be applied.
A value of 0.3mm has been assumed
for roughness coefficient, ks, which
depends upon the accuracy of laying
and jointing in addition to the quality
of the culvert surface. Where a
different value is required, the
discharge rate at the appropriate
gradient should be adjusted by the
use of the roughness multiplier
(Table 4 overleaf).
Thus, for a 2400 x 1200 section laid
at a gradient of 1 in 500 and with an
assumed roughness coefficient of
0.6mm, the discharge rate is given by
4.29 x 1.4 x 0.93 = 5.59m3/s.
The flow capacity of a culvert is
determined by a number of different
factors. In addition to the gradient and
roughness coefficient, the geometry
of the inlet and outlet and the
tailwater level can affect the mode of
flow and may prevent the culvert from
running full or under uniform flow
conditions.
In such cases the flow capacity will be
lower than the full discharge rate.

Surface loading and fill depthLoading applied at the ground surface
and weight of fill material produce a
combination of vertical and horizontal
forces on the box culvert.
Surface loading may be specified as a
standard loading type, equivalent
uniform loading or individual wheel
loads. The critical load on a culvert can
occur at minimum or maximum fill.
Each enquiry for a culvert should state
the minimum and maximum fill depth
and the amount or type of surface
loading.
It is recommended that the minimum
fill depth should be not less than
200mm or one fifteenth of the internal
width of the culvert if this is greater.
Design anddetailingBox culverts are generally designed
and detailed in accordance with the
Box Culvert Association Standard
Specification which covers materials,
manufacturing tolerances, external
loading design and detailing standards.
Box culverts carrying highway loading
or railway loading are designed to
current standards and specification as
stipulated by the client.
The lowest grade of concrete used is
C45/55 with a 20mm maximum size
of aggregate. The nominal cover to
reinforcement complying with the
exposure requirements of BS8500.
An experienced team of engineers and
technicians backed by CAD facilities
provide a flexible and comprehensive
design and detailing service enabling
the clients design and specification
criteria to be satisfied.

INSTALLATION GUIDEBox Culverts
10
Delivery and offloadingIt is the contractors responsibility to
offload the box culverts on delivery.
A hard level access area should be
provided which can be used safely by
standard articulated delivery vehicles.
The contractor should provide a
suitable crane of adequate capacity
for lifting the culvert.
For reasons of safety and economy
certain box culverts are delivered to
site on end rather than as laid, and will
require a safe method of turning during
offloading. A data sheet giving
guidance of lifting and turning is
available and is issued to clients prior
to the first delivery.
The offloaded box culverts should be
levelled carefully on a firm level base
away from the edge of the trench, and
if any further movement is required it
should be by lifting; the culvert should
never be dragged or dropped.
Bedding, laying and backfillingExcavation can be kept to a minimum
with only nominal working space
required on each side of the box
culvert. When working in trenches the
normal requirements for health and
safety must always be observed.
The base of the trench should be
uniformly prepared before laying a
200mm bedding of compacted granular
material over the full width of the
trench. A surface blinding of the fine
material will assist levelling. Local
packings are subject to settlement and
should not be used.
As an alternative to granular bedding a
concrete blinding layer is sometimes
preferred to protect the formation or to
allow a faster rate of laying the culverts.
A layer of unreinforced concrete
approximately 75mm thick on a trench
bottom which has been well prepared
to provide a uniform support is
generally sufficient.
A culvert line is usually laid directly on
the bedding starting from the
downstream end with the sockets facing
upstream, to receive the next culvert.
The trench should be backfilled as soon
as possible after the culvert has been
laid and it should be filled evenly on
each side of the trench. Backfilling
should continue in 200mm compacted
layers to reach the required depth of
cover.
Where loads from construction plantmay exceed the design load of thebox culvert protective measures willbe required. This is particularlyrelevant at shallow fill depths.
11
JointingThe culvert sections generally have
rebated joints and can be laid open, or
sealed using pre formed strips and/or
pointing materials. Reference should be
made to the jointing material
manufacturer’s specification and
recommendation for use of the product.
A system using preformed strip within
the joint is most commonly used. When
the strip is bitumen based the joint
faces should be cleaned, primed and
allowed to dry.
The strip is then applied to the internal
corner of the socket just before the
culvert is laid in the trench.
Joints are closed to a nominal gap by
pulling against previously laid culverts
with an applied load of approximately
one tonne per metre of strip plus about
half of the weight of the culvert unit to
overcome base friction, less if the unit
is suspended from the crane whilst
jointing.
Heat may be required to soften the
strip when working at low temperature.
When the box culvert is of sufficient
size for access, it can be pointed
internally with an elastomeric or
bitumen based material using a suitable
primer. Not all methods of jointing,
however, should be expected to be
completely watertight.

PRODUCT OVERVIEWOmnia Bridge Deck
Provides a solid base for deck slabs on Civil Engineering structures
12
Omnia Bridge Deck Hanson Building Products has supplied
Omnia Bridge Deck for numerous
projects to most civil engineering
contractors.
Omnia Bridge Decking is a practical
and economical means of providing
permanent formwork to deck slabs of
bridges, especially where these span
over live roads, rail tracks and rivers.
Omnia Bridge Decking can be
considered as participating formwork,
and the concrete and reinforcement in
the pre-cast plank taken as part of the
deck with corresponding cost savings
compared to traditional methods of
construction.

Design details and cross section
PRODUCT DETAILSBridge Deck
The planks are primarily designed to
cope with temporary condition loads
only, however it is very often the case
that Bridge Designers use the
reinforcement provided as part of the
permanent works design, and
furthermore often ask us to increase
the amount of reinforcement in the
plank thereby saving reinforcement in
the in-situ portion.
Hanson Building Products design the
planks to carry construction loading
but also limit deflections to span/400
and crack widths to 0.1mm in the
temporary case.
Wherever possible. the correct size
of lattice girder will be selected to
provide a chair for the top mat of
reinforcement and they are aligned
during manufacture to ensure ease of
fixing longitudinal reinforcement over
the Omnia planks.
There will normally be 3 or 4
reinforcing bars cast within each plank,
minimum 10mm diameter, maximum
16mm diameter.
The Interim Advice Note
(IAN 74/06) allows 35mm cover to
the reinforcement at the soffit.
Threaded anchors can also be cast
into the planks for supporting lighting,
drainage etc.
A typical cross section of a Bridge Deck plank shows the arrangement of the lattice girder and the reinforcement within the precast concrete.

ManufactureOmnia Bridge Deck is manufactured
to all relevant British Standards and
the ‘Specification for Highway Works’,
using C40/50 concrete in planks
300mm wide x 60mm deep, although
special widths can be manufactured up
to 600mm wide for use as infill panels
at transverse beams or abutments.
Each 300mm wide Omnia Bridge
Deck plank has an Omnia lattice girder
centrally placed and the plank is
reinforced with either 3 or 4 steel bars
10-16mm dia.
The upper surface of the Omnia planks
has a Class 2 finish as required by the
‘Specification for Highway Works’
to expose the aggregate.
This surface accommodates the
horizontal shear stresses at the
precast/in-situ interface. The
manufacturing tolerances and soffit
finish (Type F2), are also as specified
and the production process is
controlled by the procedures set out in
our model specification.
The Omnia lattice girder is at the heart
of all of the Omnia product range and
is responsible for ensuring that the
panels will span the required distance
in the temporary condition. The lattice
also acts as a physical link between
the precast panel and the in-situ
portion, and as lifting points during
erection. We will also endeavour
wherever possible to provide a lattice
girder that is set at the correct height
for placing of the top mat of
reinforcement.

DimensionsOmnia Bridge Decking can be
manufactured in lengths up to 3.80m
and depending on the overall slab
depth can be used for clear spans of
3.69m with a preferred bearing of
55mm at each end.
The graph below shows the maximum
clear span for a range of span depths.
Please contact the office for spans and
depths outside of this range.
The long edges are formed with a
chamfer to the underside, so that when
placed adjacent to each other, the
effect of a birds-mouth joint at 300mm
centres can be seen on the soffit.
Planks can be manufactured with
skewed ends to suit the shape of the
structure if necessary, however as the
maximum plank length can be no
greater than 3.80m, the clear span will
be reduced.

DELIVERY, OFFLOADINGAND ERECTION
Bridge Deck
Omnia Bridge Deck Planks are
generally laid on Structural Steel
beams, and whilst the details and
recommendations below may
apply to other structures, they are
primarily written for Steelwork
structures.
PreparationBearings
All bearings should be structurally
acceptable before any Omnia planks
are placed. Any variation in levels of
bearing will need to be addressed prior
to the planks being delivered.
Temporary Supports
Omnia Bridge Deck planks are always
designed to be erected without any
temporary props during the
construction sequence.
Minimum Bearing Dimension
All planks will be designed to have a
minimum bearing of 55mm both ends,
therefore the minimum plank length
will be ‘clear span + 110mm’ to a
maximum of 3.80m.
Prevention of grout loss
We would recommend that flanges
of steel that will be supporting Omnia
Bridge Deck planks be treated to
prevent grout loss when pouring the
in-situ section of the slab. We would
suggest a 12mm deep bituminised
compressible strip available from
a number of sources including
Illbruk Alfas at Washington
(0191-419-0505).
Safety NotesNotwithstanding the above, propping
may be necessary in the following
circumstances:-
Where the top or diagonal bars
of the Omnia lattice has been
cut or damaged.
Where the bearings are not true
and or level.
Where a bearing of less than
40mm is provided
Cantilever sections and
adjacent to the edges of
large openings
DeliveryOmnia Bridge Deck planks are
generally delivered on articulated
vehicles paletted in batches of 24
planks (6 deep x 4 wide) and will be
delivered to a previously agreed
sequence of planks and times/dates.
Depending on the spans of the planks,
each delivery will have approx. 130m²
of planks. Except where agreed
previously, the first delivery of planks
will come with a lifting frame which
should be used to lift a layer of planks.
Offloading
We would recommend that full pallets
of planks are offloaded adjacent to
their ultimate position on the
structure, and then each layer is lifted
and placed in position at a later date.
All personnel who are required
to be on the trailer bed whilst on
site should be protected from
falling from height in accordance
with “The Work At Height
Regulations”.
A lifting frame will normally be
provided to suit 4 planks and will
weigh approx 500kg, however if
required, a larger frame can be
provided (weighing approx. 750kg) to
lift 8 planks, in which case pallets need
to be placed adjacent to each other.

Lifting Weights
ErectionHandling
Units must be lifted and placed
without jerking to prevent cracking to
the panel or damage to the lattice.
Always lift Omnia panels by the lattice
with the hooks positioned under the
diagonal.
Protection against falls
In line with the PFF Code of Practice,
the erection of Omnia units will be
subject to the application of a hierarchy
of safety systems as recommended by
the HSE. There are a range of
measures available from passive systems
such as working platforms, staging,
safety nets and air bags to active
systems such as work restraint/fall
arrest using safety harnesses.
Slab CompletionPlacing in position
Panels lifted in sets of 4 will be approx
1200mm wide (8 planks will be 2.40m
wide) and will need to be butted
together to close any gap between
them, minimising the risk of grout loss.
It is recommended that a method of
setting adjacent ‘sets’ be adopted so
that each set is placed at 1200mm
dimensions. This will keep the layout of
the planks close to that on the
drawing, the amount of gaps to a
minimum, and reduce the risk of any
cutting or make-ups due to creep.
Joint Grouting
Joints will need to be addressed to
prevent grout loss during concreting.
Various methods can be used, and we
would suggest a bead of sand/cement
grout towelled along all joints.
Placing of Reinforcement
Reinforcement will need to be placed
in accordance with the Structural
Engineers requirements and one layer
may need to be threaded through the
diagonals. Other layers are placed
between and over the lattice.
Concreting
The slab will then be concreted in
accordance with the Structural
Engineers specification.
Each plank weighs 36kg/m and each pallet will normally have 24 planks.
The pallet weight will need to calculated prior to uplifting from the vehicle,
and the layer weight of 4 (or 8) planks will need to be calculated before
lifting to the structure.
Pallet Weight
A pallet of 24 planks 3.60m will weigh:- 24 x 3.60m x 36kg/m = 3110kg
Use the calculator below...
………. Planks x …………. m x 36kg/m = ………kg
Layer Weight
A layer of 4 planks 3.20m long plus frame will be:-
4 x 3.20m x 36kg/m = 461kg plus 500kg frame = 960kg4 planks x ……… m x 36kg/m = ………… + 500kg = ……….
A layer of 8 planks 3.40m long plus frame will be:-
8 x 3.40m x 36kg/m = 979kg plus 750kg frame = 1729kg8 planks x ………. m x 36kg/m = …………. + 750kg = ……….
PREFABRICATED WALLPANEL SYSTEMS
Hanson have developed a suite ofprefabricated panels which includeprecast concrete, masonry orcomposite panels of brick/block andconcrete with or without insulation.
These may be used for retaining walls,
parapets, bridge abutments, flood
defence systems or as both external
and internal walls for buildings
Where speed of construction and a
high quality finish are necessary,
Hanson's QuickBuildTM and FloodWallTM
products provide rapid installation of
finished masonry components.
Wall panels may consist of single leaf
masonry of clay brickwork, concrete
blockwork or natural stone, or a
composite precast concrete/masonry
construction. Wall lengths can vary
up to 9m.
