RFB – 235-25

Item 1: Questions and answers listed below:

Question 1: Addendum 4 mentions different completion dates for locks 2 and 3. Construction Sequence Note 1 on sheet A04 of the plans mentions work can proceed concurrently at Locks 2 and 3. Is this still the case? A01 – A10

Response: Work may be performed concurrently at Locks 2 and 3 in accordance with the Plans for Construction and the Technical Specifications.

Question 2: Is this project tax exempt?

Response: The project is NOT tax exempt.

Question 3. In light of the ongoing volatility in material costs due to tariffs and trade regulations, can you clarify how tariffs will be handled for this project? Specifically, will there be any provisions, such as allowances or escalation clauses, to ensure a fair and level playing field for all bidders in the event of tariff-related price fluctuations after bid submission?

Response: No provisions, allowances, or escalation clauses will be added to the Contract. To help mitigate some of the risk associated with material escalation, the Contractor may purchase all required materials required for Locks 2 and 3 and invoice for stored materials.

Question 4: What permits will be required to be purchased by the contractor for this project?

Question 10: For the sheet piling at lock 2, detail 1 on sheet B04 indicates #57 backfill up to the waterline, then concrete up to elev 448.8’. Is this just for the piles against the Lock Land Wall or will this apply to all PZC26 sheet piles?

Response: This detail only applies to the sheet pile belly against the Lock Land Wall. No. 57 stone backfill shall be placed up to the waterline then concrete placed to elevation 448.8 feet within the sheet pile belly against the Lock Land Wall. Following concrete placement to elevation 448.8 feet within the sheet pile belly, the sheet shall be cut flush the top of concrete and capped with the concrete sidewalk.

See detail below for clarification. All areas outside of this sheet pile belly, shall be placed as shown on Drawings B06 – B08.

Question 11: The Historical Drawings for Lock #2 show details for the guide walls starting at Buttress No.

1, but do not show any details for the guide wall between Buttress No. 1 and the upper end of the lock wall (140.7’ ). Can details regarding the existing guide wall between buttress No. 1 and the Upper end of lock wall be provided? Are there existing buttresses behind this 140.7’ of guide wall?

Response: The cross sections available to understand the composition of the Upper Guide Wall between the buttresses and lock wall is shown as "Section of Old Crib" on Drawing D07.

Drawing D07 indicates that the buttresses were only installed on the upper 150-ft of the guide wall with buttresses 6 through 9 being demolished in 1980 as shown on Drawing D12.

Question 12: Both sites show existing underground electric apparently feeding assumed river monitor gauges. Please clarify how this will be addressed- contractor responsibility to remove/provide new? If this is contractor responsibility, can these be taken offline until completion of work and then new/reinstallation take place?

Response: The underground lines for the headwater gauges are owned and maintained by USGS.

These lines have been relocated ahead of construction by USGS to better accommodate construction activities. Some equipment associated with the headwater gauges has been left in-place at its’ previous location for the time being. The Contractor shall coordinate with USGS prior to starting excavation at each site. The approximate location of the relocated lines are shown below. In accordance with Section 024100, Paragraph 1.10.4, the USGS Concrete Pad and Platform at Lock 2 shall remain undisturbed during construction. Furthermore, in accordance with Section 024100, Section 1.10.6, the Contractor shall maintain existing utilities to stay in service and protect utilities against damage during excavation and demolition operations.

Lock 2

Lock 3

Question 13: Please confirm/clarify river traffic during construction. Will the contractor be required to allow river traffic to pass through the locks at all times? Can data be provided for estimated watercrafts?

Response: The Contractor is not required to maintain traffic through the lock during construction. The Owner has requested the Contractor support lockages if possible provided the lockages do not adversely impact the Contractor’s schedule and can safely be performed. This also applies to the Rockin’ Thunder Adventure dates listed in the Special Conditions (Article 4).
