The availability or use of information provided in the responses to bidder's inquiries is not to be construed in any way as a waiver of the provisions of Section 2-1.03 of the Standard Specifications or any other provision of the contract, the plans, Standard Specifications or Special Provisions, nor to excuse the contractor from full compliance with those contract requirements. Bidders are cautioned that subsequent responses or contract addenda may affect or vary a response previously given.
Q1) Is epoxy coating reinforcement required for the minor concrete structures such as type GO,G1,GDO and G2 inlets? Please advise
Q2) Where might we order full-size sets of drawings? Thank you
A2) Go to this website http://www2.dot.ca.gov/hq/esc/oe/weekly_ads/index.html Navigate yourself down to where its says "Ordering Project plans & Specifications"
Q3) Are Cross Sections availible for this project?
A3) Cross sections are available from Coastal reprographic Services, 880 Unit B Via Esteban, San luis Obispo, Ca. 93401, telephone and fax (805)543-5247.
Q4) Typical Sections seem to indicate that only the SB half of route 17 is to be overlaid. The NB side of 17 is all shown as existing, but appears to be drawn such that an overlay is planned. Please clarify whether the NB half of 17 is to receive an OGAC overlay or not.
A4) Yes it will receive an OGAC overlay.
Q5) Per the Materials Handout, the system that is quoted by Barrier Systems essentially excludes damage to the quick change barrier. Since the barrier system is a very significant dollar amount, will the state pay additional if the barrier system is damaged by the public?
A5) Per section 7-1.16, "Contractor's Responsibility For The Work And Materials," until the acceptance of the contract, the Contractor shall have the charge and care of the work and of the materials to be used herein, etc.
Q6) Are there available copies of stationed cross sections taken through the proposed soil nail walls, with which we could determine the width of access benches for the driling equipment at various stages?
A6) Cross sections are available from Coastal Reprographic Services, 880 Unit B Via Esteban, San Luis Obispo, Ca. 93401, telephone and fax (805)543-5247.
Q7) PLEASE CHECK QUANTITY TAKEOFF FOR ITEM 42 STRUCTURAL CONC RETAINING WALL . OUR QUANTITY TAKE OFF SHOWS QUANTITY OVERRUN BY MINIMUM OF 30 % MORE THAN CAL TRANS QUANTITY.
A7) The quantities have been reviewed and there are no changes. Bid per the current contract bid documents.
Q8) Drawings for Wall Numbers 175 and 179 show trees within the right of way. With this information given, it is possible to quantify the number of trees that are to be removed. Drawings for Wall Numbers 165 and 169 do not show trees. Given the fact that existing trees are to be protected to the maximum extent possible, the contractor needs to be able to establish a count of trees to be removed. Is additional information available to accurately determine a count of trees to be removed?
A8) Bid in accordance with contract plan
Q9) Further to question above, we are concerned about trees that are to remain. A jobsite visit reveals numerous large trees upslope of the planned wall construction. We are concerned that disturbing root growth of trees that are upslope of the construction may substantially weaken the trees' ability to remain stable, and could result in very large trees falling into live traffic.
Will Caltrans allow for the potential of additional tree removal for safety purposes at Force Account?
A9) The contractor is required to keep the job site safe as stated in the Standard Specifications and Special Provisions.
Q10) Both the Materials Information handout and a jobsite visit indicate the possibility of rocky excavation during the construction of soilnail walls, yet there is no plan for the installation of any measure to prevent falling rocks from entering the traveled way during non-construction hours.
Will Caltrans consider revising the project requirements to add protection from the potential of falling rocks during non-construction hours?
A10) The contractor is required to keep the job site safe as stated in the Standard Specifications and Special Provisions.
Q11) Can the clearing limits be outlined in the field before bid date? There is no way we can tell which trees are to be removed on the steep slopes in the wall vicinities without physically measuring the fog line and this can't be done safely without closing the No. 2 lane SBND.
A11) The clearing limits cannot be placed in the field prior to the bid opening date.
Q12) Please clarify the 300 WD and 300 WD Plant establishment period as inclusive or not inclusive.
A12) Planting is expected to be completed early in the project. Therefore, Plant Establishment can be completed within the 300 working days established for the project.
Q13) Please show existing traffic monitoring system limits so we may evaluate impacts, if any.
A13) All traffic monitoring systems should be shown on the plans.
Q14) We have completed our takeoff of Roadway Excavation using the cross sections. Our takeoff is substantially lower than the bid quantity.
We are concerned about the potential loss of budget for fixed costs with a reduction in pay quantity. Will Caltrans revisit the bid quantity for roadway excavation?
A14) Bid in accordance with contract plans.
Q15) In the Plans, sheet 11, L-6, Station 181+28, a CAT Crash Cushion is called out.
The CAT Cushion is not included in the Specials under "Alternate Crash Cushions".
Is the CAT acceptable or not?
A15) Bid it as you see it.
Q16) The special provision does not indicate any specfic part number for the alternative crash cushion system. The width of each system is not known. What are the manufactures part numbers or the width of each of the systems?
A16) The construction details in the contract plans specify the width of the system.
