Inquiry #5: Reference Sheet 142 of 175 "Girder Elevation-Auxiliary Spans", details a transition from end block to I-section of 10.75" which is the transition for a Bulb Tee section. The typical transition length for an I-Girder as specified is 6". Please update the plans to avoid costly steel form modifications.
Better still, it would be better to remove the end block entirely to reduce the girder weight as cranes erecting the precast will most likely utilize existing bridge and reducing girder weight will reduce crane size and loading on existing structure.

Inquiry #18: Precast Girders Erection Over Corte Madera Creek:
Setting of precast girders from land from Bent G-12 to Bent G1-2 looks to be problematic without a trestle or derrick water access. Derrick water access is limited by (E) narrow train trestle width and is not an option. A temporary trestle does not appear to be an option given the State's ROW and ESA areas shown on L-1.
Please advise if CalTrans will allow the erection of precast girders from a crane located on the (E) northbound off ramp bridge under a full ramp closure. Bidding contractors absolutely need to know if this construction approach will be allowed on this project for the installation of precast pedestrian bridge elements.
Inquiry submitted 07/20/2020
