Durability engineering and asset rehabilitation

Extend the life of your assets safely and economically, with practical durability design, condition assessment and rehabilitation solutions.

With our fact-based approach to risk management, GRIT develops fit-for-purpose durability and rehabilitation solutions for plant, equipment, structures and civil assets. Our durability engineers consider the required service life, operating environment and risk profile of each asset to help clients make practical, informed decisions about maintenance, intervention and investment.

Our team has hands-on experience in the durability of concrete and steel structures, pipelines, bridges, industrial and marine assets. This real-world understanding allows us to design for durability from the outset, balancing short-term investment with future maintenance challenges and costs, based on your needs.

By taking a whole-of-life view, we help you make informed decisions that reduce unnecessary intervention, maintenance costs and disruption over time. Our focus is on resolving issues with minimal impact and risk to the environment or people’s safety, providing maximum economic, operational and ESG benefits.

GRIT’s durability and rehabilitation engineering services include:

Durability assessment and rehabilitation of below-ground services and infrastructure, drainage systems and pipelines, concrete and steel structures, jetties, process equipment and plants, storage tanks, and industrial and commercial buildings.
Durability design and design-for-durability reviews for new and existing assets, including assessment of our own and other engineers’ or architects’ designs to identify likely maintenance issues, schedules and costs, and add value with pragmatic improvements.
Durability specifications, scopes and quality-control requirements for new-build, maintenance and rehabilitation projects, helping ensure materials, detailing and protective systems are appropriate for the required service life and exposure environment.
Building Code and standards advice, including durability design guidance and review for compliance with Clause B2 Durability, NZS 3404.3 durability requirements for steel structures, and other relevant New Zealand Standards.
Corrosion and deterioration assessment of existing steel and concrete structures, piping and process equipment, including internal assessments. We combine durability and corrosion knowledge to forecast deterioration rates, assess remaining service life and develop practical intervention options and budgets.
Rehabilitation strategy and lifecycle planning, helping asset owners prioritise maintenance, repair and replacement based on condition, operational constraints, risk and long-term value.
Expert witness and technical advisory services for legal matters involving durability, deterioration and asset-performance issues.
