Inquiry #2: Micropile anchorage assembly's bearing plate is currently called out as 8" 40ksi XXStrong steel pipe (ref. Page 54 of 69). Procurement of this material is expensive and difficult compared to the less expensive and more common 8" A500 Schedule 80 steel pipe. Is A500 Schedule 80 steel pipe an acceptable substitution for the as-given specification?

Inquiry #3: Section 8-1.04C of the Special Provisions states, Start job site activities within 55 days after receiving notice that the Contract has been approved by the Attorney General or the attorney appointed and authorized to represent the Department. Because this project is estimated under $200 million and per Section 3-1.04 Contract Award of the Standards, the low bidder should expect Contract Award within 30 days after bid opening. 55 days later would fall then within the rainy season in which, per Section 10-1.03 of the Special Provisions, No work is allowed in the Santa Ana River Wash from October 15 to April 15. Is it the intention of the Department to begin the projects Working Days within the 2018-2019 rainy season?

Inquiry #4: Section 14 Environmental Stewardship requires a Contractor Supplied Biologist (CSB) to perform several activities prior to the start of construction activities. 30 days prior to commencement of project activities, the appropriate CSB shall submit a Nesting Bird Plan and Pre-construction plant surveys. Do these 30+ days of biologist work and reporting count towards the contract work days?

For Species Protection Area 3, Interstate 10 Bridges, the specs require a 6 month lead time for a CSB Bat Survey of the existing bridges before work can start on the bridges. Here are a few of the spec sections in question. "A CDFW-approved CSB bat biologist shall conduct a bat roosting habitat suitability assessment of any locations with potential for roosting on the I-10 bridges that may be removed, altered, or indirectly impacted by the proposed project." "If the appropriate CSB determines any portion of the project contains habitat suitable for bat roosting or as a maternity roost, the appropriate CSB shall survey those locations, no less than six (6) months prior to the commencement of project activities." "No work shall commence onsite prior to CDFW review and approval of the bat survey report." Do these possible 6 months for Bat Survey before construction on the bridge begins count towards contract working days?

"Work will be conducted outside of the bird nesting season of February 15 to September 15. If work cannot be conducted outside the nesting season, the appropriate CSB will need to conduct a preconstruction nesting bird survey no more than 3 days prior to commencement of project activities." Is it Caltrans intent for the contractor to not work from February to September? What qualifies as "work cannot be conducted"? The specifications do not provide criteria for what reasons would be valid to allow the contractor to work during this period.

Inquiry #6: Plan Sheet #25 shows that the contractor is required to excavate under the existing footing to create roughly a 10" void between the bottom of the existing footing and the soil.

Inquiry #11: Please provide Lane Closure Tables with special working hours for the approach slabs which allow for longer working windows. From the closure hours allowed on Closure Charts G1 & G2, you need to deduct at least 1.5 hours to allow concrete to cure and at least an hour for traffic control. Also, when working on the approach slabs in the middle lanes, a buffer lane is needed on either side for a total of 3 lanes closed. We are only allowed to have a 3-lane closure for 3 hours, and with traffic control and cure time, that reduces the actual working hours on middle lane approach slabs to less than an hour. This makes the approach slab construction near impossible.

Inquiry #17: "If the appropriate CSB determines any portion of the project contains habitat suitable for bat roosting or as a maternity roost, the appropriate CSB shall survey those locations, no less than six (6) months prior to the commencement of project activities."

Inquiry 4: Do these possible 6 months for Bat Survey before construction on the bridge begins count towards contract working days?
Response: Yes

Inquiry 4: Do these 30+ days of biologist work and reporting count towards the contract work days?
Response: Yes

If the Contractor Supplied Biologist (CSB), determines that the bridge has a habitat suitable for bat roosting, then the CSB must complete a survey, no less than 6 months prior to the commencement of project activities. This 6-month delay would make it impossible to finish work in the Santa Ana River before the October 15th dry season deadline, and the project would not be completed until after April 15 of 2020. Caltrans should have all these biologist surveys completed before or during the 55 days before the start of job site activities. The responses in Inquiry 4 and the Specification requirements in Section 14, Environmental Stewardship, will likely delay the start of work and cause considerable overtime costs, and might lead to a multiple month delay that pushes the project into the next dry season in 2020. Please consider revising or clarifying the specifications to alleviate these requirements.
