The Condek System advantages
are many and can be summarised
as follows:
Off-site build
Truly modular car park system
Integral gutter system,
watertight deck surface
Fits any shape any size
Fast programme completions
The system enjoys the same benefits as ClearSpan but tubular steel sections
are replaced by universal columns & beams. It provides a span of 15.6m and
an alternating grid module of 2.4m/4.8m with the utilisation of cross bracing.
Both systems have the flexibility of being utilised as a
permanent or temporary solution with the capability of
being multi-storey.
Flexibility of Layout
Due to the truly modular nature of both systems there are a wide range of
layout possibilities and overall car park sizes that can be achieved. The final
layout can also easily be modified to suit any future developments or
possible rearrangements of an existing layout. Additional modules can be
attached to a current layout by removing barriers and extending the modules
in any direction. This also allows for the size to be reduced if required.
Foundations
Not all sites require foundations however this is entirely dependant on
ground survey conditions and client specifications. If foundations are
required they are typically a mass poured concrete pad foundation on
every column. This will be carried out prior to the commencement of the
deck’s site construction, with minimum disruption to the normal operation
of the existing car park.
Ramp Design
Due to the nature of site conditions the ramp is generally a bespoke item
tailored to suit each individual site. The ramps are constructed of standard
structural steel sections. Ramps with a steep gradient have transitions
sections at the top and bottom as per design recommendations, thus
removing trip points and allowing for a smooth motion for vehicular traffic.
Control of Rainwater
The deck modules & infills are cambered to allow for water to naturally run off
to a grating situated at either end of the 15.6m span. There is a bespoke
gutter box positioned directly underneath the grating which collects the water
which is then released into the existing storm water sewer. Any water which
permeates through the deck surface is then collected by the underlying profile
sheet and flows into the gutter box as previously described.
Lighting
The underside light fittings typically give an average 100 lux lighting level
which are incorporated in each module unit. There is an emergency lighting
system should a power failure occur.
The deck is illuminated via stylish 3m high lamp standards at agreed grid
positions, this will again allow the end user to select the luminance
requirement to suit the individual location.
GRP Deck Panels
The surface of the deck is made from a UV chemical resistant surface know
as GRP. This is a composite material with an Isophthalic resin. The deck
finish incorporates a non slip surface which is created by having carborandum
chips embedded into the GRP.
These panels have a life expectancy in excess of 50 years and excellent
thermal stability capable of withstanding a temperature range of -40 to + 150
degrees Celsius. They can also be manufactured to a wide range of colours
however black tends to be the colour of choice.
Paint Specification
The protective coating is expected to give a life expectancy of 15+ years to
first maintenance as per ISO12944 C3 environment, high durability painting.
The longevity can be extended up to 25 years using an enhanced painting
system.
Modular System Testing
Load testing has been carried out on the composite decking by both Messrs
Sandberg and Queen Mary University to provide structural integrity data on
the panels under the designed UDL and point load conditions.
Test reports are available upon request.
