Inquiry #5: Given the salt fog exposure of the steel pedestrian structure and the difficulty of access for maintenance painting in the future, we would suggest that the same Zinc, with two Polysiloxane top coats coating system be used as was used on the new bay bridge. The slightly increased material cost pales beside the savings to be realized in increasing the maintenance cycle.
Secondly given the need to increase the maintenance cycle as noted above and the impacts of the marine environment of the bridge painting operations both shop and field should require 3rd party NACE III inspection

Inquiry #15: I am reaching out to you as both of you have “stamped†portions of the Gilman Street POC project. We have had a number of contractors reach out to us for clarification on the luminaires selected for this project, as we represent Leotek, the manufacturer of the E-Cobra series used by the city of Berkeley. The Leotek luminaires specified in the project have a part number that may need to be changed, as there are no 90W options available. We worked with Berkeley to replace a number of failed street lights a few years ago, and I believe the product needed for this application is from the E-Cobra family, but using a lower wattage/output. I have included the link from the manufacturers website, as well as a snippet from the last schedule we used for the Berkeley Street Lighting project. The fixtures used for this project had a custom drive current to meet the lighting criteria requested by the city, but the types for your project may require something different. Based on the mounting height noted in your plans (12’ +/-), I don’t think you would need much more than the EC1-6M2-MV-WW 530mA version, or possibly the 700mA version (Type 2 or Type 3 depending on the distribution needed).
https://leotek.com/wp-content/uploads/e-cobra-m2-series-spec-sheet.pdf
EC1-6M2-MV-WW-2-GY-WL-430 Flux +/- 10% - 4100 Wattage 34W
EC1-6M2-MV-WW-3-GY-WL-430 Flux +/- 10% - 4000 Wattage 34W
EC3-10M2-MV-WW-2-GY-WL-600 Flux +/- 10% - 8300 Wattage 74W
Please review this information and let me know your thoughts, as we would like to ensure you have the proper solution specified for your client. Feel free to bounce back on email or call me on the number listed below.

Inquiry #26: We have received a Solicitation from "GRAVIX" - Earth Wall Products to furnish Precast Retaining Walls for Retaining Walls 25R & L and 13R & L.

Inquiry #28: Bid Item 48 - Remove Irrigation Facility - requires contractors to remove the underground irrigation system per the plan sheets IR - 1 & 2 (sheets 85 & 86 of 221). This work is within the footprint of the Tom Bates Regional Sports Complex and indeed upon field reconnaissance appears located under the existing synthetic sports surfacing at the Complex. Without further direction our assumption is that we dig through the synthetic sports surfacing, remove the irrigation facility to the limits as indicated and backfill the trenches necessary for the irrigation removals. We will do no synthetic sports surfacing restoration as nothing is indicated or detailed. Is this Caltrans intention for completing this Bid Item?
