Inquiry #1: Specification Section 2-1.06A states, “Forms for the total base bid are forms without with additive item 1 in the form name. Forms for the total base bid with additive item 1 are forms with additive item 1 in the form name.” Please provide forms as stated above. No forms with any reference to “additive item 1” are included with the bidding documents. Additionally please clarify how the bidders are to provide pricing for additive item 1 as this item does not appear in the bid schedule.

Inquiry #3: Specification Section 2-1.12B (2) states, “Submit a DBE Commitment and a DBE Confirmation form for the total base bid and a DBE Commitment form and a DBE Confirmation form for the total base bid with additive item 1. Include the information specified in section 2-1.12B (2) with each form.” Producing the required paperwork for the Commitment forms and the Confirmation forms for a $280 million contract is an extensive undertaking. Requiring that this essentially be done twice (1 for the base bid and 1 for the base bid and additive item 1) and be included in the larger Good Faith Effort documentation within 3 business days of bid opening is going to raise the possibility of incomplete or incorrect paperwork. The last time this project bid, issues with Good Faith Efforts led, in part, to rebidding this job. Requiring the contractor to do twice the work in the same amount of time only increases the possibility that this project will end, again, in lengthy bid protests. Please consider extending the time allotted for contractors to produce this paperwork or require only one set of documents that includes the additive item to make things simple.
Inquiry submitted 01/21/2019

Response #1:
(#3)-We are not able to extend the amount of time the bidder has to provide the Department with the DBE documentation.

This is a standard Federal Requirement, and we are constrained to the 5th day after bid opening.

The requirement for providing a DBE Commitment and a DBE Confirmation forms has been a part of all of the Additive bid contracts advertised.

Inquiry #4: Specification Section 2-1.12B (3) states, “ Under the conditions specified in section 2-1.12B(3), submit a DBE Good Faith Efforts Documentation form for the total base bid and a DBE Good Faith Efforts Documentation form for the total base bid with additive item 1.” Producing the required paperwork for the DBE Good Faith Efforts Documentation form for a $280 million contract is an extensive undertaking. Requiring that this essentially be done twice (1 for the base bid and 1 for the base bid and additive item 1) and be submitted within 5 days (3 business days) of bid opening is going to raise the possibility of incomplete or incorrect paperwork. The last time this project bid, issues with Good Faith Efforts led, in part, to rebidding this job. Requiring the contractor to do twice the work in the same amount of time only increases the possibility that this project will end, again, in lengthy bid protests. Please consider extending the time allotted for contractors to produce this paperwork or require only one set of documents that includes the additive item to make things simple. In addition please clarify if Caltrans expects the contractor to have separate solicitations for the two required Good Faith Efforts. Caltrans is requiring us to submit two separate DBE Good Faith Efforts presumably because the additive item created the possibility of two separate and distinct scopes of work. In addition to separate Good Faith Effort Documentation is the Contractor expected to have separate solicitations to the separate scopes of work? If so does this extend to separate advertisements, outreach phone calls, faxes and mailings?

Response #2:
(1) Please consider extending the time allotted for contractors to produce this paperwork.

The time allotted is a Federal Requirement, can not extend the time for submittal of the DBE documentation.

(2) Or require only one set of documents that includes the additive item to make things simple.

The Department needs to evaluate the base contract, as well as the (Base + additive) contract. This requires separate submittals, one for the base contract, and one for the (Base + additive) contract.

(3) In addition please clarify if Caltrans expects the contractor to have separate solicitations for the two required Good Faith Efforts.

Per section 2-1.12B(3), a Good Faith Efforts documentations is required for both the base contract as well as the (Base + additive) contract.

(4) Caltrans is requiring us to submit two separate DBE Good Faith Efforts presumably because the additive item created the possibility of two separate and distinct scopes of work. In addition to separate Good Faith Effort Documentation is the Contractor expected to have separate solicitations to the separate scopes of work?

The solicitations for the scope of work for the base contract, and one for the base + additive contract can be part of one solicitation or two separate solicitations, this is a business decision that needs to be made by the bidder.

(5) If so does this extend to separate advertisements, outreach phone calls, faxes and mailings?

This is a business decision that needs to be made by the bidder. As long as the Department receives a Good Faith Efforts documentation for the base contract, and another for the base + additive contract, how this is handled is up to the bidder.

Inquiry #6: Regarding Special Provisions Section 39-2.09A(3)(e) Sample; Does this need to be sampled after the Start-Up Production sample? And/or, is the contractor to assume this is for every sub-lot of material sampled or just provide a sample one time during the project for each Long Life HMA material produced? Please provide clear guidance as to when these samples should be taken.
Inquiry submitted 01/30/2019

Response #1:
(#6)-(1). Does this need to be sampled after the Start-Up Production sample?

Yes, the samples need to be collected after the start-up production.

(2). Is the contractor to assume this is for every sub-lot of material sampled?

No, the every day samples are not for every sub-lot, just once per day per mix.

(3). Just provide a sample one time during the project for each Long Life HMA material produced?

No. There are one time samples, and there are every day samples.

Response #1:
(#12)-Your inquiry has been received and is being reviewed.
Response posted 02/08/2019


Response #2:
1. No, the "HMA-LL Performance Requirements" table is only applicable for JMF approval. Please refer to Section "39-2.09A(4)(e) Department Acceptance" for the applicable limits.
2. The limits in the "HMA-LL Performance Requirements" table were developed after accounting for laboratory testing variabilities. Since the table is not applicable during placement, it does not need to account for the production variability.

Response posted 02/15/2019




Inquiry #13: 39-2.08A(4)(b)(vii) – Action Limits and Corrective Actions: If the Contractor is out of specification in one or more of the corrective action limits for HMA-Long Life Pavement will the material be accepted if corrective action is taken? Should it be assumed that the acceptance will be based on Section 39-2.09A(4)(e) Department Acceptance which does not include permanent deformation or fracture potential test?

Inquiry #20: What is the basis for the requirements in Table HMA-LL Performance Requirements in Section 39-2.09B(2)? Were these requirements developed considering both contractor and agency risk and is there sufficient data to indicate they are achievable using locally available aggregates and liquid asphalts?
Inquiry submitted 02/08/2019

Response #1:
(#20)-Your inquiry has been received and is being reviewed.
Response posted 02/08/2019


Response #2:
The requirements in the table are based on testing of a mix made with locally available materials being used at the time in the region. Aggregates and RAP were sampled from all available sources that could be identified within reasonable trucking distance of the project location, and all available binder sources, including different grades that could likely be used. The materials were sampled and tested in the late summer and fall of 2017. The results from the testing of a mix made from materials selected from those sampled were used to set the requirements. The requirements were set using statistical analysis to have Caltrans taking most of the risk of specimen preparation and test variability by setting the requirements for the contractor's average test values at the 2.5th percentile confidence interval from the testing results.

Inquiry #21: Section 39-2.09A(4)(a) – Quality Assurance: This section states “In addition to JMF verification, you may request the Department may also verify up to 2 times for each of the tests included in the "HMA-LL Performance Requirements" table for each HMA-LL mix type”. Is the intent of this language to allow the Contractor to re-test the same material which failed previously during verification testing or is it to allow the Contractor to reproduce the material at the plant and only re-test the properties that failed?

Inquiry #22: Section 39-2.09A(4)(a)(i) notes that after acceptance of the JMF submittal, the Department verifies the JMF within 30 days of receiving all verification samples. We need clarification on the following:
a. For the mix verification testing (hot drop), does the department verification include those tests outlined in the “HMA-LL Performances Requirements Table” shown in 39-2.09B(2)?
b. For the mix verification testing (hot drop), does the contractor need to perform those tests outlined in the “HMA-LL Performances Requirements Table” shown in 39-2.09B(2) and submit them the Caltrans as part of the verification process?
c. If required to be tested by the Contractor as part of the mix verification process and given that AASHTO T 321 is not required during production, is it really Caltrans intention that the Contractor purchase, install and train staff for this test (AASHTO T321) that would only be needed for the mix verification phase (hot drop)?

Response posted 02/08/2019


Response #2:
a. Yes, note that there are additional tests that are not listed in the "HMA-LL Performances Requirements" Table
b. Yes, contractors need to submit test results for those tests, they can use UCPRC for these tests but will count towards the number of free tests allowed.
c. No, It is not the intention for contractor to run AASHTO T 321. It is up to the contractor to weight the cost of having UCPRC running the test vs. running them in house.

Inquiry #23: As outlined in precision and bias statements in AASHTO T378, the Permanent Deformation test method has a high degree of variability (both within and between labs). Was this requirement developed considering both contractor and agency risk and is there sufficient data to indicate this production requirement is appropriate based on the high degree of variability of the AASHTO T378 test method?

Response #1:
(#23)-Your inquiry has been received and is being reviewed.
Response posted 02/08/2019


Response #2:
The variability of the test and the risk to the contractor was considered by requiring the contractor's average results to meet the 2.5th percentile of the test results for the baseline mix properties. This takes most of the risk of test variability off of the contractor and puts it on the agency. Graphical analysis for this risk was presented at the pre-bid meeting for the project.
Response posted 02/15/2019




Inquiry #24: There are no precision and bias statements available for AASHTO TP 124, the Semicircular Beam Fracture Potential test method. Was this requirement developed considering both contractor and agency risk and is there sufficient data to indicate this production requirement is appropriate based on no precision or bias statement being currently available for the TP 124 test method?

Inquiry #25: On the Caltrans website for the “Sac 5 Corridor Enhancement Project” there is a document titled “Long-Life Hot Mix Asphalt Pavement Presentation.” On page 20 of this document there is a flow chart. There is a “No” option next to the “Contractor Believe JMF is Ready” flow chart step. If “No” is chosen, it is assumed the next steps indicate that UCPRC will be available to assist with the JMF mix design development testing for AASHTO T321, T378 and TP 124 prior to performing the official JMF verification. Is this assumption correct?

Inquiry #27: The Special Provisions have deleted parts of, and added the following text to, section 39-2.01C(4)(a) “Place HMA on adjacent traveled way lanes such that at the end of each work shift, the distance between the ends of HMA layers on adjacent lanes is from 5 to 10 feet.” In addition Section 39-2.01C(4)(b) has been deleted. These changes will now require the contractor to square up all paving each shift all the way across the highway, because it no longer allows the use of the tapered notched wedge or allow drop offs 0.15’ and less. This requirement will greatly increase the cost, as well as the number of days needed to complete the project. Many areas of the project will have 5 to 6 lanes of traffic in its final configuration, plus an inside and outside shoulder. This will mean that on many paving shifts the paver will have to back up and pave the next lane up to 8 times in a single shift. This will greatly reduce the production rate of paving and in many cases it will cause the production to be up to 4 times slower than that achieved the first time this project bid. Other issues will be impacted as well with this change in the specification; such as the need to constantly short feed the paver to get shoulders paved with mainline the same night and greatly reducing the length of the highway that is completed each night. These issues will produce a less than optimal quality and ride-ability of the paved surface. Additional bump grinding will be required, further adding to schedule delays and overall cost. Although Caltrans may view the elimination of the tapered notch wedge as a public safety issue, if done properly it will ensure the traveling public will have to drive through this portion of the work for many less days thus providing less overall risk to the traveling public. Please consider allowing the 0.15’ drop off (standard specification 2018 language for Section 39-2.01C(4)(a)) and the tapered notched for the leveling, long life overlay work and the OGFC overlay work at a minimum. The impact of this small specification change cannot be overstated.

Inquiry #39: Response # 2 to Bidder Inquiry # 1 posted 2/14/19……. “updated the electronic bid software to allow the additive bidding.” Although the prime contractors are familiar with Caltrans electronic bid software many subcontractors and suppliers have no reason to use this software and in many cases are completely unaware of it. Prime contractors will likely not get pricing from subcontractors and suppliers for the work included in the additive item as they are not aware how to price this work if they do not see a bid item in the bid schedule for it. Please issue and Addendum updating the bid schedule to include a bid item for the additive work scope.
Inquiry submitted 02/14/2019

Response #1:
(#39)-Prime contractors seeking pricing from subcontractors and suppliers for the work included in the additive item should direct them to the contract plans designated as "ADDITIVE". These plan sheets show the specialty and roadwork items which compose the lump sum amount for the additive bid item.

Inquiry #41: Special provision section 3-1.02A states 3 different scenarios for comparing bids. This appears to be in conflict with Section 10126(C) of public contract code which states "Whenever additive or deductive items are included in a bid, the bid solicitation shall specify only ONE method to determine the lowest bid." Please clarify if the determination of the lowest bid is base bid plus the additive item or total base bid only.
