2. HGOB TDTC for Gap Crossing Equipment - A cyclic fatigue test should be conducted to identify sensitive areas for monitoring in service to obtain some insight into crack growth rate, critical crack length, inspection, and repair techniques, and for safety reasons to identify that the structure can still sustain the maximum working load during its useful life.

Where a Supplier is able to assist with elements of the requirement, they are requested to provide details including:

• Rough Order of Magnitude (ROM) costs (where a costing is provided as a range, please also indicate most likely cost) - Technical details of any proposed solution
