The project is located on the site of the existing aquatic centre that had recently been demolished, in ground works consisted of pad and strip foundations, with associated cast-in HD bolts for structural steel frame and intermediate foundations for tilt panel construction.
Site preparation and concrete works relating to the pool shells was critical as there would be no opportunity to re-visit these structures following associated foundation works.
Structural components for the building frameworks consisted of tilt panels to the numerous areas of the dry side facilities such as the gym, administration office, staff training room, group fitness area and plantrooms.
Structural steel framework formed the main pool and wet side facility structural solution, this consisted of a column and beam braced frame, with long span truss members providing clearance over the pools. A ‘3 coat’ epoxy surface treatment was required throughout the scheme due to the environmental factors of a building of this nature.
The main entrance area was supported by numerous feature “tree” columns integrated into the structure and façade treatments, these were accomplished by providing curved PFC elements with plated face and edge treatments.
The associated civil works consisted of 4 no stormwater retention and attenuation cells within the southern car park area, 2 no sewer pump stations each one catering for a separate section of the site facilities (dry side including toilets and changing) to the south, and wet side facilities to the north.
The main car park area had been reorientated and additional parking provided. The external paving/hardstand has been extended by over 5100m2 of exposed aggregate in-situ paving.
The external finishes included the main feature cladding to the building which consisted of full height Kingspan “Evolution Axis” 1000mm width insulated panels, with integrated aluminium window, door and curtain walling elements. The roof was a combination of Bondor “SolarSpan” insulated panels and traditional built up system to curved entrance areas. Timber louvres had been installed to the roof openings above the external ASHI-YU pool area and vertically to the creche walls. The Northern aspect had been provided with full height glazing sections and the lower areas were fully operable to allow access to external landscaped areas and the existing splash pad/play park. The existing grandstand was refurbished with new anti-slip flooring, additional stairs and wheelchair bays, new stainless-steel handrails and TGSI installation.
Service installation consisted of conditioned areas to all parts of the building with the exception of the outdoor leisure, ASHI–YU and existing pool area, chilled water with heat recovery air conditioning system, integrated with the geothermal system to provide heating during the winter months. This is delivered by a series of air handling units for heating and cooling and fresh air provision to manage chlorine level within this environment. The pool heating is provided by a Geothermal bore located to the Northern area of the site.
Pool services were upgraded within the existing plantroom area with new pumps, filter media, chlorine lines and controls, the new plantroom extension was fully fitted out to cater for the new pool installation.
A high-quality finish to all areas was specified and this was combined with the durability requirement for a facility of this nature and material choices were reflective of these requirements and the volumes of visitors anticipated at the facility.
“Very highly rated, PS Structures would be in my top 3. They have made this project enjoyable.” Andrew Barnett – Director City Projects, City of Armadale
