Please see ORBA comments and questions in regards to Consultation Review on: Update to Guidelines for Inspection and Field Acceptance of Glass Fibre Reinforced Polymer (GFRP) Reinforcing Bars.

• There’s nothing in the guideline on GFRP acceptance subsequent to sandblasting a construction joint (CJ), between the deck and barrier wall for example.
 Has the MTO considered what is an acceptable condition after a CJ is abrasive blasted in accordance with OPSS 904?
 What the damage would look like, if any, after abrasive blasting around GFRP?
• OPSS 929 will have us wrapping/protecting all the individual barrier wall dowels likely after removing the horizontal bars prior to blasting to satisfy 904.07.04.02. Is this the MTO’s expectation?
