Shaping Land
Connecting Communities
From land to legacy, Cook Costello’s civil engineers deliver the infrastructure that helps communities thrive. We design practical, cost-effective, and buildable solutions for subdivisions, stormwater, utilities, roads, and earthworks.
For nearly 50 years we have supported projects across New Zealand’s cities and regions. Our local experience helps developers, councils, and property owners turn complex challenges into successful outcomes. We reduce risk, save time, and deliver civil works that stand the test of time.
Our Civil Engineering Services
Land Development & Subdivisions
Transforming raw land into functional, buildable sites by designing lot layouts, services, and infrastructure that comply with council requirements and support future growth.
Earthworks & Erosion/Sediment Control
We design and oversee safe earthmoving, cut-and-fill operations, and slope stabilisation while managing erosion and sediment control to protect waterways and the environment.
Roading, Pavement & Infrastructure Design
From driveways and carparks to local roads, our engineers design transport networks and pavements that are durable, safe, and cost-effective, supporting long-term accessibility and efficiency.
Three Waters: Stormwater, Wastewater & Potable Water
We provide integrated design of stormwater drainage, wastewater systems, and drinking water supply to ensure developments are serviced reliably and meet environmental and public health standards.
Flood Risk & Hydraulic Assessments
Our engineers model flood hazards and design mitigation measures to reduce risk, protect assets, and support compliance with council flood management requirements.
Geometric Design
We deliver detailed road and site geometry, including alignments, grades, and intersections, ensuring safe vehicle movement and practical construction outcomes.
Utility Coordination & Infrastructure Servicing Reports
Civil engineers plan and coordinate essential services such as power, telecoms, and gas, preparing servicing reports that streamline consent approvals and construction delivery.
Construction Monitoring, Supervision & Certification
We provide on-site monitoring, contract administration, and formal certification, giving confidence that civil works are built to specification and meet regulatory requirements.
Why Choose Cook Costello for Civil Engineering Services?
What sets Cook Costello apart is our integrated, end-to-end approach. Our civil engineers work alongside in-house geotechnical, structural, geophysical, and surveying teams to deliver coordinated solutions that are practical and buildable. This collaboration means smoother designs, faster approvals, and fewer surprises during construction.
With nearly 50 years of experience and local knowledge across Auckland, Christchurch, Whangārei, and Wellington, we design civil works that are efficient, compliant and ready to build. Partnering with Geocivil, we also provide ground and earthworks testing during construction to verify alignment with both the design intent and regulatory requirements.
