NZ Express, the largest road transport carrier of containers out of Lyttelton Port required a new distribution warehouse near the port due to their continual growth. Kennaway Drive located in the Christchurch suburb of Woolston was chosen as the ideal location for this new warehouse within the Portlink Industrial Estate.

KCL Engineering Services designed a 150mm PT slab 43m x 46.5m with tendons spacing at 2.1m and 2.3m centres using BBR CF405 Flat anchorages. The PT slab design parameters applicable to NZET were CBR= 20% at finished course level, 65kN back to back racking post load with a 2.0m width aisle between the racks. The 300m3 slab was poured in one day by Conslab and upon reaching 30MPa it was stressed to 80% UTS (147kN).
