FIMA was employed by Sisk to provide civil works to this project. FIMA erected safety fencing prior to carefully dismantling the Victorian-age Teak Glass house, labelling and palletising each component for specialist restoration. New planter beds were installed and filled with specialised treated topsoil.
FIMA removed an old 12m long cast iron bridge which was used by pedestrians to cross into the rose gardens from the Botanic Gardens over the river Tolka. The new bridge design entailed FIMA augering piles 12m into the ground under both ends of the new bridge at the piers to support it and forces that may be exerted on it due to any future flooding of the Tolka. Due to limited accessibility of the site, the piling rig and all materials had to be lifted in over a nearby building at night time. The new bridge was then lifted into position, again over the nearby building during an early morning shift using a 200t crane.
Landscaping, paving and footpaths were then completed as was drainage and ducting for lighting. This was a very special project to be involved in and it proved that construction and refurbishment can be carried out in a way that protects our sensitive national heritage buildings. The OPW signed off on successful completion of the works.
