This project is for the installation of a new fully equipped gymnasium above a live and busy shopping centre. The existing roof was removed from the building and a new steel structure introduced to provide the additional height required. A new floor slab was fitted off the new steel superstructure, as the existing slab was not rated to take the loadings required for the gym. Due to the awkward access to the site and serious traffic and parking restrictions a tower crane was erected to allow all materials and plant to be lifted from Kilmacud Road over the building to the work areas. The existing shopping centre remained open and fully operational during the works.
– Demolition and removal of existing roof and top floor superstructure – Temporary weathering membrane on existing slab – New steel frame fabricated off site and fitted in situ – New metal deck and roof membrane system – Reinstatement of mansard roof detail – New windows – Acoustic rubber pads fitted at all steel connection to the existing structure to avoid noise transfer – Works to common areas (out of hours) to allow for new entrance to the unit – Use of a tower crane with reach capacity of 70 m to facilitate the works – Partial road closure and traffic management on Kilmacud Road – 500 tonne mobile crane utilised for erection and dismantling of tower crane – Fire stopping and compartmentation of the new unit from the existing units
