Whats important to us?

For NPDC, it is essential that the selected consultant demonstrates a strong understanding of and commitment to the Building (Dam Safety) Regulations 2022, and NZSOLD Dam Safety Guidelines 2024. Experience in the design and construction of High PIC dams will also be valued. The consultant must be able to provide the services of a Dam Safety Recognised Engineer, with the qualification and competency for certifying and auditing dam safety assurance programmes, annual certificates and potential impact classifications. This service must be guaranteed for the duration of the contract.

The project requires a proactive, risk-based approach to dam safety management, with tailored solutions that reflect the unique characteristics of each dam. Long-term collaboration is key, so continuity, reliability, and knowledge transfer over the five-year period are highly valued. Clear, timely communication and transparent reporting are critical to support decision-making and regulatory compliance. NPDC also places high importance on environmental stewardship, cultural sensitivity, and community engagement throughout the program. The consultant must be prepared to include Pukekura Park Dams from Year 2 onward, ensuring all five dams are comprehensively managed under the safety program.
