The Facts About Cracks - A Guideline to Assessment and Acceptance of Reinforced Concrete Pipelines
Many thousands of kilometres of steel-reinforced concrete pipe have been installed all over New Zealand, in many size and varying conditions. They continue to provide satisfactory service, years after installation.
The reinforced concrete pipe industry is guided by two standards for manufacture, durability, design and installation. Significant changes to the industry in New Zealand have taken place over the last 30 years, and this has required these two Standards to be updated. The two standards are:
AS /NZS 4058:2007 “Precast concrete pipes – pressure and non pressure” – (This replaces the outdated Standard NZS3107:1978) outlines the minimum requirements for materials and manufacture of precast reinforced concrete pipes.
AS /NZS 3725:2007 “Design for installation of buried concrete pipes” – (This replaces the outdated Standard NZS/AS3725:1989) sets out the methods and data required for calculating working loads on buried-concrete pipe, relating this to the correct selection of reinforced concrete pipe and specifying details of the installation.However, over these last 30 years there has been a number of significant changes take place in the industry impacting on site construction work and the installation of reinforced concrete pipe, with respect mainly to productivity, construction machinery, site supervision, inspection and constraints on time, budgets and skills.
This seminar will explore the impact that these issues can have on reinforced concrete pipe, as well as relating them to the changes that have taken place in the industry. The seminar will also look at how the appropriate implementation of New Zealand Standards for concrete pipe can provide specifiers with a durable and sustainable pipeline system.

Facts About Cracks
Setting the Standards
Stormwater Drainage - Avoid the Risk!
For a society to be prosperous and vibrant it is essential that it remains safe, healthy and secure. Pipeline systems throughout Australia and New Zealand contribute significantly to the social sustainability of any community. But how do you know if the pipeline servicing your area is effective and safe?
The concept of risk analysis threads its way through all the requirements of sustainable and durable stormwater drainage development. Selecting the right product and material for the right application to match service life with design life will reduce the risk of minor and major damage, giving the community confidence in the infrastructure affecting their lives.
The capability of a stormwater drainage pipe to perform as expected for the design life of a project is a fundamental engineering consideration, especially when considering the risk factors that can be encountered, and in the economic environment where life cycle cost analysis and asset management requirements have been set in place to ensure (and demand) sustainable buried infrastructure.
Steel reinforced concrete pipe has contributed to the success of stormwater drainage systems since the early 1900’s. The concrete used in SRCP is inherently a very durable material that will last for over 100 years if it is manufactured with good quality control, designed properly in its intended environment and appropriately selected, installed using current practice and expertise, and managed diligently with good engineering judgement.

Setting the Standards in Concrete Pipe
Seminar brief: Steel reinforced concrete pipe relies on quality manufacturing, careful design consideration, correct placement and installation, and positive asset management to ensure that a pipeline system remains durable and serviceable for the duration of its life. Australian and New Zealand Standards are essential documents to consult when considering these pipelines, and in recent times, those relevant to reinforced concrete pipe publications have been revised.
