project profile
Preparing the existing sports hall for its
new use proved another challenge. A single narrow strip - a mere 1.5m at its thinnest point - provided the only access to the hall. The team had to remove a section of the elevation to get the necessary piling equipment and plant machinery into the building to facilitate the work. The building was stripped back to its
shell and treated with spray-on insultation to protect the steel trusses and to seal the hall and prevent any impact onto the adjoining dry site. Monmouth has soft ground as well as a
high water table, which called for some innovative temporary works solutions and creative piling designs to support the new swimming pool. The existing concrete slab in the sports hall needed to be broken out before excavation work could commence. However, traditional temporary works solutions could not be implemented due to logistical constraints. An innovative solution was developed to install a king-
post wall to form a u-shape around the deep end of the pool. I-beam posts were driven into the bedrock at 1.2m intervals and then railway sleepers were slotted between the beams on top of one another to form a sacrificial support structure. Another bespoke element saw the use of steel tube piles instead of CFA piles. This solution minimised noise and vibration and reduced the volume of arisings produced. A further innovation was the use of a
sprayed concrete system to cast the slab and walls of the pool. Rejecting a typical formwork solution, again due to logistical constraints and to provide a quicker application, ISG used a specialist lightweight concrete mix. This unorthodox approach delivered significant time savings – with the entire pool completed within a week and designed, built and tested to BS EN 1992-3:2006 standards.
close collaboration Built to ASA standards, the 25m, five lane
pool occupies most of the hall. However, the building also had to accommodate a spa comprising an eight person sauna, eight person steam room and six person spa bath. ISG has worked with Alliance Leisure on
many projects and their collaboration meant they were able to take a pragmatic approach to the project, value engineering as and when necessary. This included working with Alliance Leisure to redesign the spa area to make better use of the space and include a treatment room. “You can only make these types of
improvements on projects where you have such close collaboration. The client knew it was a difficult project and trusted Alliance and us to come up with a solution,” says Gibson. “Construction is not about putting blocks
on top of each other, it’s about creativity, innovation and changing perceptions.”
