Entuitive noted that:
"...there is no information available regarding the condition of the cable system (cable net and anchorages) which, over a period of years, is likely to have deteriorated but the extent of which is unknown. It is critical that a testing agency be commissioned to establish a level of confidence regarding the current condition of the structure."
"...a review of the condition of the bonded cable system must be undertaken and an ongoing deterioration mitigation plan must be followed per our recommendations. It is also critical that loading applied to the roof system remain within the allowances noted in this report."
"Given the history of the roof membrane discontinuities and probability of moisture contact within the unbonded strands, corrosion of the strands is occurring. There is also the potential of corrosion of the cables."
"Unfortunately, conditions of the cable anchors are concealed at this time. Further investigation is required."
Entuitive found roof cables that were exposed and showed signs of rust. It said it's possible that four cables have experienced breaks over an 18 year period.
