Interspan provided the design and installation of post-tensioning

After having already completed two 8-level carparks, each approximately 100,000m2 in size, the Sydney Airport Commission engaged Lend Lease to extend the second of these by adding 4 additional levels.

Since Interspan had provided the design and installation of post-tensioning to the original carparks, we were naturally the first choice to undertake the post-tensioning to the extension works.

Once again, tight deadlines whilst maintaining a safe worksite were paramount, and Interspan delivered in these regards.
