Question 1

Posted: 3/4/2024

Question: Could the CADD files please be made available to the contractors via addendum to help us with our bidding takeoff process?

Response: DWG files are available through Alliance Consulting Engineers, Inc. Upon the fee paid to Alliance Consulting Engineers, Inc. and receipt of the signed Electronic Media Agreement, the files can be released. Information to obtain the files can be found on the Advertisement for Bid.

Question 3

Posted: 3/4/2024

Question: If, the bridge is not in this bid package. Why is the bridge sheet piling included a part of this bid package?

Response: Bridge and Sheet Pile Plans will be included as an Addendum.

Question 5

Posted: 3/18/2024

Question: Can you please clarify what the depth of the select fill subgrade layer shall be under the roadway? Plans indicate a 12" layer on sheet C8.1. Shall all bidders figure this 12" subgrade layer in their base bid, and any additional depth beyond 12" shall be paid per unit price, if encountered?

Response: Correct, roadway section requires 12-inch compacted subgrade to 95% Standard Proctor per Sheet C8.1-Roadway Details (2 of 3) (Drawing No. 01,1644-D28, dated January 2024). In the event there is a failed proof roll, then the remediation of these areas will be addressed using the unit price established for Fill Import and Soil Amendments.

Question 7

Posted: 3/18/2024

Question: Who is responsible for the third party geo technical testing, proof rolls, and inspections?

Response: The owner will be responsible for third party testing and will be procured through Alliance Consulting Engineers, Inc. The awarded bidder will be responsible for performing their own due diligence to ensure the project area is ready for testing and third-party inspections will be conducted for final materials testing. Compensation for any failed testing completed by the third-party inspector, and therefore requires a re-test, will be the responsibility of the awarded bidder.

Question 9

Posted: 3/20/2024

Question: Is there a percentage of work that the prime contractor must do with their own forces in each segment?

Response: We have already responded to this question. Please see the addendums.

Question 11

Posted: 3/20/2024

Question: Per the geotechnical report, bi-axial geogrid (tensar BX-1200) will be required along the entire subgrade within the wetlands (segment 2). Shall all bidders include this geogrid in their segment 2 bid? Also, the geotechnical report suggest a unit price for this geogrid, so can revised bid forms be issued showing unit prices for the geogrid - per SY, muck and haul off unsuitable soils - per CY, and also import fill for replacement of muck excavations - per CY?

Response: We have already responded to this question. Please see the addendums.

Question 13

Posted: 3/20/2024

Question: Considering bridge plans have just been issued per addendum 1 today and the last day for questions is tomorrow, which does not allow for enough time to review bridge plans, can the bid date be pushed back at all so bridge contractors have enough time to review project documents and submit questions for clarification?

Response: We have already responded to this question. Please see the addendums.

Question 15

Posted: 3/20/2024

Question: For pay item "Earthwork - Select Fill & Soil Amendments", shall the contractor include both mucking with haul off & replacement of muck with import fill within this pay item? Also, are the quantities for these pay items assumed to be what muck and fill quantities are anticipated to be for each segment?

Response: We have already responded to this question. Please see the addendums.

Question 17

Posted: 3/21/2024

Question: - Can substitutions for the NZ-26 Sheet Pile be proposed? - What is the wait period for a production pile re-strike? - When will 100% bridge drawings be distributed? - It appears the shaft diameter is shown as the same as the cased diameter. This is not possible, the auger will not pass through the casing. Please advise. - Please provide the DHEC, DOT Encroachment, and USACE wetland disturbance permits - If DHEC, Encroachment, and USACE permits have not been obtained, when will they be available to the contractor? - Please provide quantities on the bridge drawings.

Response: We have already responded to this question. Please see the addendums.

Question 29

Posted: 3/28/2024

Question: • The 910 LF of guardrail appears to include the anchors pay length in them. Would you like us to still price the anchors separately & the 910 LF? • Does this project mention anything about bridge connections? The guardrail should terminate into the bridge with connectors, but none are listed in the plans/this bid form.

Response: We have already responded to this question. Please see the addendums.

Question 31

Posted: 4/2/2024

Question: 1, Per the geotechnical report, structural fill should extend at least 5' from the edge of pavements, but there is no thickness mentioned for this fill. Can you please clarify how thick the structural fill is required to be in the 5' areas outside of pavement? Is it bottom of subgrade to finish grade? 2, Per addendum 1, item 5, if muck & fill of the subgrade beyond 12" is needed, the county will utilize the contractors unit price for "Earthwork - Select Fill & Soil Amendments", but that unit price only covers import fill operations and not mucking, per clarification 8 in addendum #2. Therefore, can a unit price be established for mucking and haul off since there is no way to know how much mucking will be done or needed and there's no where to cover that cost for this bid at this time? 3, Can you please confirm that the contractor does not need to figure any geogrid fabric in this bid and that after the bid, the contractor will submit a unit price to the county for this to be placed on subgrades as the geotechnical report recommends?

Response: See Addendum
