C&B Drainage Contracting Ltd completed the public stormwater and wastewater infrastructure works for a residential development in West Harbour, Auckland. The project involved multiple deep manholes and pipeline installations, with excavation depths generally reaching approximately 4–5 metres throughout the site. Due to the depth of the excavations and site conditions, trench shoring was required across the entire project, with careful control of excavation, shoring and construction safety. All works were completed in accordance with Auckland Council and Watercare requirements.
