Wellington's Indian High Commission project was completed on schedule despite strenuous site and time constraints.

Building successful foundations

 

The Indian High Commission were upgrading from their existing site to Pipitea Street in Central Wellington. The new building went through a Tender process where Ebert Construction won the Main Contractor role with Lattey successfully winning the deep pile foundations as subcontractors.

​

Lattey’s were responsible to overcome the difficult ground conditions and complete 44 x 750mm diameter and 86 x 1200mm diameter concrete piles at depths ranging from 14metres to 19 metres.

​

Considerations

​

As we are working in Wellington City Centre the site was very constraining with limited space. The methodology of the construction phase was needed to be thought through thoroughly. As ground water was a big factor Lattey’s were required to use a polymer product to stop the holes collapsing before concrete was poured. 

​

Construction

​

Lattey’s were required to use multiple plant including an 80ton Crawler Crane, 40ton Soilmec piling machine and a 12ton Excavator to complete the 44 x 750mm diameter and 86 x 1200mm diameter concrete piles. To meet the tight program a minimum of 2 piles were required to be poured each day. This required pouring 40 cubic metres of concrete and installing 10ton of reinforcing steel per day.

​

Lattey completed the program on time and budget and built a strong relationship with Eberts construction.
