Herd Street

Spencer Holmes Limited provided the structural and civil engineering services to the strengthening of the Herd Street post Office building (Chaffers Dock Apartments) and new building known as the Boathouse. Design and construction was carried out simultaneously with the adjoining Waitangi Park Project.

Approx contract value $43M.
The project was completed in 2007.

The existing five storey Herd Street post Office building was strengthened to current code and had two levels added to it. The new four storey Boathouse was designed with a basement car parking structure below mean sea level, with precast retaining walls providing tanking in a reservoir type design. The building is piled in reclaimed ground, and the ground was improved to minimise liquefaction. A seawall was also formed to support the buildings with a with caisson pile retaining wall.
