Inquiry #6: Regarding the 047315 Composite Girder Strengthening (Bid Item 63) Scope:
Sheet 77, Detail B indicates that a bi-directional carbon FRP material is to be used for the U-wrap structural strengthening application to the beams. Typically, U-wrapping of beams for shear strengthening is accomplished with a uni-direction FRP application (fibers oriented vertically/around the beam). The flexural strengthening has already been accomplished via the bottom uni-directional strip specified. Please clarify/confirm that a uni-directional CFRP product is acceptable for the U-wrap application (assuming all other minimum properties and design value requirements are satisfied).

Please confirm that the U-wrap CFRP application to the beams indicated should consist of a unidirectional carbon FRP material installed with fibers oriented in the hoop direction, and not a bidirectional CFRP product as indicated on Sheet 77, Detail B and sheet legend.
