Karaka, Auckland2019 - Ongoing

Karaka Village Development

Karaka Village is a large-scale greenfield development delivering an integrated rural community of up to 950 lots. The masterplanned development provides a diverse range of living options, from medium-density housing to standalone homes and lifestyle properties, complemented by expansive open spaces that will continue to operate as a working farm. Community-focused amenities include a village square, village green, and a network of pocket parks. Calthom has been involved since project inception, delivering comprehensive civil engineering services across all stages. Our scope includes masterplanning, consenting, detailed design, and construction phase support through to final certification, ensuring a cohesive and high-quality infrastructure outcome.

Mount Wellington, Auckland2025

100 Carbine Road

The redevelopment at 100 Carbine Road delivers a substantial new industrial facility, including a 13,000m² warehouse and associated office space designed to support heavy manufacturing use. Located alongside active industrial sites, the project required a considered approach within a constrained brownfield environment. Calthom provided civil engineering design and construction observation services, responding to challenging ground conditions and the presence of contaminated materials encountered during early works. Our involvement focused on delivering practical and resilient infrastructure solutions, including stormwater management, bulk earthworks, and three waters design, ensuring the site performs effectively for long-term industrial use.

Takanini, Auckland2024

Takanini Village

Takanini Village forms part of a growing town centre hub, delivering commercial infrastructure to support retail, dining, and community-focused spaces within an active urban environment. The works involved redevelopment within an established site, including new carparking, servicing, and integration with existing buildings and infrastructure. A key component of the project was the diversion of an existing deep sewer to enable the planned development. Calthom provided civil engineering design and construction observation services, supporting the delivery of practical and well-coordinated infrastructure. Our involvement focused on three waters, bulk earthworks, and site servicing, ensuring a functional and robust outcome within a constrained brownfield setting.

Onehunga, Auckland2024

270 Neilson Street

The redevelopment of 270 Neilson Street delivers a modern 2-hectare industrial facility supporting large-scale wine bottling and distribution. Constructed alongside an existing operational warehouse, the project required precise coordination to seamlessly integrate new and existing structures within a constrained brownfield site. Calthom provided civil engineering design and construction observation services, addressing the complexities of the site with a focus on robust stormwater management. This included careful design of overland flow paths, water quality treatment, and hydrological mitigation to manage flood risk and ensure resilient, high-performing infrastructure. The result is a well-integrated and efficient industrial facility delivered within a challenging live environment.
