Inquiry #20: How does CalTrans foresee the in-creek work periods unfolding? Per CalTrans specs, Contractor is required to verify the column dimensions. Generally speaking this involves potholing the footings and recording their elevations. For Bent 2 columns at Alpine Rd, that involves "in creek" work and a Temp Creek Diversion (TCDS) just in the 1st upcoming dry season 2023 ... and then coming back in dry season 2024 to actually install the casings (recognizing that column casings can't be fabricated/coated and delivered within the 2023 dry season). This involves a 2nd TCDS and postponing the creek channel work until 2024 dry season. With 300 working days this seems to be a tight schedule.

Inquiry #21: I'm trying to understand the in-channel streambed restoration aggregate requirements. The specs appear to boiler plated and therefore have no real bearing on the constraints and realities of this project. Under SP 72-13.02 (Streambed Mat'l) & SP 72-14.02 (Structural Rock) it is stated "ESM Type 1 must consist of existing streambed material, that is excavated within the grading limits with diameters between 2 and 22 inches mixed with rock of the gradations shown. Imported rock must comply with section 72-2 and be angular." Similar requirements for ESM-2 and all Structural Rocks. The gradation specs for these materials are VERY SPECIFIC. It's not realistic to assume 1) that the Contractor is going to setup an aggregate processing yard onsite and make the required gradations 2) that the existing native material has this amount of rock within it. I'll standby and wait for you to tell me to bid per plans and specs.
