• Conduct a number of destructive tests on representative samples of cast iron main to determine a baseline level of strain that  the tool will need to able to accurately detect and measure / the level at which cast iron would be expected to fail.

• To conduct a feasibility study on the options for inserting the tool into and extracting it from tier 2 cast iron mains to inform the design and development of the final tool.

This phase of the project will identify the level of strain at which cast iron mains can be expected to fail and confirm the tools ability to detect this.  Furthermore, it will identify & develop the options for entering the tool into the mains and traversing within the main.
