Inquiry #2: Regarding the Armorguard barrier. On pages SC-6 and SC-9 of the stage construction and traffic handling plan it shows a run of Armorguard and pinned k-rail on each side of the workzone. Per the Armorguard manual, there is 6.5' deflection when impacted. Being that the workzone is so narrow, is there any way to anchor the Armorguard in the same fashion as the k-rail since this appears to be a minimum deflection area?

Response #2:The AmorGuard cannot be staked to the roadway to minimize deflection. It is not designed or approved that way either at Caltrans or FHWA. If the Armorguard is being connected to concrete barrier via the methods provided by the manufacturer/distributor, the deflection near the connection points should not be as great as a standalone ArmorGuard system.

Inquiry #4: The typical sections on Sheet C-11 & C-12 show the limits of the Geosynthetic Reinforced Embankment. Under what bid item does the excavation get measured and paid for (to the limits shown)? If the excavation occurs outside the limits of the existing pavement/surfacing, will the excavated material be considered lead contaminated? Depending on CT answer, quantities may need to be updated accordingly.

Inquiry #6: In the Information handout there was only 3 ADL samples and a map with 14 locations. Can you post the full ADL report so we know if we have to add any additional sampling or data that might be needed from the landfill. As you state in the specs Caltrans does not pay for additional sampling and data required by the landfill. So if there is additional sampling we need to cover the costs. Thank you

Response #2:The three numbers provided in the Information Handout are the 95% UCL statistical average results for all of the combined soil samples and do not represent 3 individual samples. The concentration data (laboratory report) and sample location maps provided in the Information Handout are sufficient information for disposal as type Z-2 at the class 1 landfill and no additional sampling is required.
