Comment Classification: Controlled Unclassified Information (CUI)

There is a paint spec included and identifies the areas to be painted. However I do not see any discussion of lead abatement for existing metals that will have to be coated near the new work.

How will this be handled?

Will the coffer boxes require painting after there use on this project?

On: Jun 23 2021.

Government Response. . The lock chamber armoring is a routinely maintenance item, so the presence of lead based paint is low. The contractor should take all precautions for lead paint testing that are detailed in 09 97. In the event that lead based paint is encountered then it will be disposed of per 01 57.

The coffer boxes will not need to be repainted in their entirety. In the event that the contractor damages the boxes and they need to be repaired before returning them to USACE, then the repair area will need to be painted. On: Jul 19 2021

9296089 Contracting n/a n/a 01 14 00.00 para. 1.5

Comment Classification: Controlled Unclassified Information (CUI)

Most of the work is inside the lock along the lock wall and underwater. Will KTR be required to vacate the lock when a barge is ready to lock through during daylight hours? This will probably occur June through January.

Government Response. . Spec 01 14 00.0046 paragraph 1.5.2 states "If the lock can be returned to service outside of working hours then the closure period may last up to 1 month. If the lock cannot be returned to service outside of working hours then the closure period may only last up to 14 consecutive days that will be followed by a 10 day period where traffic is not to be impacted."

The intent of this statement is to give the contractor some flexibility. The contractor can shut to lock down to all traffic 24hrs a day but that type of closure may only last 14 consecutive days followed by a 10 day period were traffic is free to move. If the contractor can reopen the lock to traffic over night then the outage can last 30 consecutive days. If the contractor can open the lock to traffic at night then there will be no need to vacate the lock for barges during the day. On: Jul 19 2021

3.3.5

Section 03 31 00, Subpart 3.3.5 Time Interval Between Mixing and Placing states:

"Concrete shall be placed within 30 minutes after discharge into non-agitating equipment.

When concrete is truck-mixed or when a truck mixer or agitator is used for transporting concrete mixed by a concrete plant mixer, the concrete shall be delivered to the site of the work, and discharge shall be completed within 1-1/2 hours after introduction of the cement to the aggregates. When the length of haul makes it impossible to deliver truck-mixed concrete within these time limits, batching of cement and a portion of the mixing water shall be delayed until the truck mixer is at or near the construction site."

The current wording is saying to add the aggregates to the truck and most of the water at the plant and then add the cement and remaining water to the truck once it's on site. Was the intention of this paragraph to say it is allowable to add the aggregates and cement to the mixer truck at the plant and then add the water to the truck once it arrives on site?

Government Response. . We will change the specifications to note that the water shall not be added until the truck arrives to the jobsite. The contractor shall provide a water tank with a gauge to measure the water added and a high range water reducer must be added for workability. On: Jul 20 2021

Please reference attachment labeled "B.08.02 Att 2 – Plans (concrete demo clarification).pdf:

Sheets SD201, SD301, S-201, S-301, and S-506 all show the concrete demo scope in elevation and plan views as well as showing details for replaced sections of the Wall Armor Rubbing Bars. I've attempted to use green and blue boxes to show possible conflicts in defining hatching and demolition limits that appear to conflict between the elevation and plan views.

For the Landwall demolition shown on elevation A1 of SD201 the green box is to the left of the slot and the blue box is to the right of the slot, both are shown as "to be removed". Plan Detail A1 on SD301 only shows hatching on the left (green). Please confirm that a similar shape must be removed on the right side of this slot (blue) in order to create room for the embedded rubbing bar for wall armor tie-in piece. Plan Detail A6 on S-301 also appears to only show reinforcement details for the left side (green) with missing details for the right side (blue). When scaling dimensions from the sheets mentioned above they exactly match the dimensions given on S-506 details C3 (green) & C5 (blue).

Please provide dimensions & reinforcing details that are to be used in the apparent missing scopes (blue).

On sheet SD201 the left side (green) demolition stops at Elev. 132.04 at the bottom of the Wall Armor Rubbing Bar, but the right side (blue) continues down to Elev. 121.5. Please also confirm that no demolition in these "wings" (green & blue) is required below the 132.04 elevation as there is no need to re-embed a Wall Armor Rubbing Bar below this elevation for all locations on Landwall and Riverwall slot modification locations.

When working within the coffer-box we believe this can be done, however when the coffer-box is in place at the downstream - landside location, will the coffer-box cause conflict with the passing barge and the lock trolley system?

On: Jun 30 2021.

Government Response. . This configuration will conflict with the use of the Tow Haulage. This will simply be another restriction that we detail in our notice to navigation. This additional requirement on industry should not affect the contractor.
