In our engagement with Lendlease during the bidding for the Geraldton
Hospital project, we focused on delivering structural value engineering, posttension
design, and construction methodology for this critical infrastructure.
Located in Geraldton, this 2-storey hospital development presented unique
challenges and opportunities for innovation in structural engineering. We were
tasked with developing an alternative structural design that diverged from
the originally documented design. The alternative design we proposed was
centered around the use of post-tensioned slabs, which allowed for a reduction
in slab thickness by approximately 25%. By employing post-tensioned slabs, we
not only streamlined the construction process but also introduced significant
improvements in the structural design’s efficiency and effectiveness. This
approach not only led to material savings but also to labor savings. Specifically,
our design required 30% less reinforcement compared to traditional reinforced
slabs, translating to reduced labor and installation time. Furthermore, we
advocated for the conversion of all columns to precast, enhancing the project’s
prefabrication level and streamlining the construction timeline.
An additional measure was the rationalization of structural steel for the
roof and facade, further contributing to cost and material savings. Our
comprehensive approach to structural design and construction methodology
resulted in Lendlease submitting the most cost-effective bid, accompanied by
the shortest project timeline among competitors.
The sustainability impact of our work on the Geraldton Hospital project
is notable, with an overall reduction in materials used and an accelerated
construction program. By integrating innovative structural engineering
practices, we not only contributed to the project’s economic efficiency but also
to its environmental sustainability, underlining our commitment to responsible
engineering solutions.
