McLaughlin & Harvey Construction and University of Ulster
York Street, Belfast, Northern Ireland.
Design, Fabrication and Install GRP Floor Grating and Support Structures for 20 no. RiserGuard Floors of the New Campus.
GRP RiserGuard System
McLaughlin & Harvey Construction Limited was awarded the contract for the new University of Ulster campus situated on York Street in Belfast. The new
state of the art development comprises 3 no. new buildings with a total floor area (gross external) of 85,736 sqm, and a max. height of 12 storeys.
Relinea was awarded the sub-contract by McLaughlin & Harvey Construction to supply and install glass reinforced plastic (GRP) floor grating and
support structures throughout the service risers of the new campus to provide access to ventilation ducts for maintenance purposes. .
Relinea was awarded the sub-contract by McLaughlin & Harvey Construction to supply and install glass reinforced plastic (GRP) floor grating and support
structures throughout the service risers of the new campus to provide access to ventilation ducts and pipework for maintenance purposes.
The confined service riser areas within the new campus buildings were congested with ductwork, limiting the available points of fixing the structural support
Lightweight flooring materials and support structures were required for the service risers so that the installation team could safely and easily handle
the materials into the site and through the service riser floors. Material that could be easily fabricated on site and did not require hot works permits
were also important benefits to the customer.
There was very limited scope for fixing points on this project, but Relinea’s design team developed a bespoke solution that could also accommodate the
3 kN/m2 design load in conjunction with a specific fixing system. The Design team worked in partnership with the M&E team to develop an individual
design for each riser to accommodate the riser layout.
The lightweight yet high strength structure of GRP was the optimum solution for the service riser flooring and support structures. The materials could
be safely and easily manually handled by the installation team through the floors of the constricted service riser areas whilst ensuring all site health
and safety measures were strictly adhered to.
Relineas GRP RiserGuard system uses GRP Open Mesh Moulded Grating is a bi-directional product which unlike uni-directional steel grating spans in both
directions which means that opes can be cut into it and these do not have to be banded or supported (up to 200 mm diameter). This gives GRP Grating
a hudge amount of flexibility and can significantly reduce the costs of fabrication in the riser environment.
In addition fabrication can be carried out on site with the use of hand tools and there is no requirement for hot works permits. This reduces risks on
site whilst ensuring alterations to the initial layout can be changed easily and quickly.
The use of GRP structural beams complemented the GRP grating which are up to 80% lighter than an equivalent steel section. The beams could be easily distributed
around the site and installed by a 2 man team and avoiding the need for any heavy lifting gear. Also the beams could be trimmed as required to allow
for variations in the concrete.
Relinea provided McLaughlin & Harvey with comprehensive design support and advice throughout the scope of the project.
