Construction Schedule – add the following: The contractor shall submit a digital copy of the construction schedule in the format used by the scheduling software including the complete network analysis.

CLARIFICATIONS

1. In order to generate borrow materials for use at Site 14, the construction sequencing criteria allows for excavation in the Site 15 ASW RCC area. Simultaneous embankment work at each site is not permitted. Refer to the Construction Sequencing Criteria document.

2. Regarding the use of multiple shifts, the solicitation states that multiple shifts are possible for multiple tasks such as, but not limited to, the Site 15 upstream work and RCC work at both sites. The use of multiple shifts requires a request in writing and a contract modification.

3. It was pointed out during the job showing presentation (slide 30) a (3) month period that Site 15 reservoir could be drawn down 10’ below permanent pool. The 10’ drawdown time is limited to 3-months (not any particular 3-month period). This applies if the principal spillway/impact basin work is not performed when the reservoir is drained. Refer to the Construction Sequencing Criteria document.

4. Regarding the draining of Site 15 for the upstream embankment work, normal operation of Site 15 water withdraw is through the summer (June-November). The intent is to keep Site 15 operational as long as possible through the summer. A contractor could implement the 10’ drawdown ahead of the August 1st milestone to get a head start on the draining.

5. At Site 15 to facilitate access to the upstream slope stability berm, installation of a temporary access road could be proposed on the dam’s embankment by the contractor as a part of their Staging and Stockpiling Plan (refer to CS8). The contractor must verify that any work associated with installation of an access road does not extend into or cause damage below the planned embankment excavation limits.

Revisions / Clarifications Page 3 of 4

6. At Site 15 to facilitate access from the proposed RCC staging area (downstream left side) to the upstream portion of the ASW, a temporary access road could be proposed by the contractor as a part of their Staging and Stockpiling Plan (refer to CS8). Any changes to the limits of disturbance would require a contract modification to be issued by the Contracting Officer and the contractor would be responsible to work with sponsors to obtain an amendment to any appliable permitting impacted by the modification such as the NPDES permit or Army Corp of Engineers permit. The contractor would also be responsible for all work and costs to permit, install, remove, and restore any additional disturbed areas to original or better conditions.

7. The operability of the Site 15 drain gate and water supply gates is not known. The PSD reports that the two water supply gates in the riser were inspected in 2020 by divers, but they are unsure if they were exercised at that time. The use of the drain gates is at the contractor’s risk. Refer to CS 11 for contractor’s responsibilities of stream diversions.

8. A list of required work plans for Site 14 and Site 15 is included in this addendum.

9. Contractors must prepare, submit, and receive approval of all work plans, product and material submittals, and shop drawings outlined in the contract documents prior to initiation of work or ordering materials included in the submittals. Contractor should plan for a 14-calendar day review of the initial submission, time for contractor revision & resubmission, & a 14-calendar day review of the revision. Additional revisions & reviews will be required as needed until approval. No additional contract time or delays will be incurred for additional reviews and revisions of inadequate work plans.

10. In regard to installation of approved dewatering systems, these systems can be installed prior to the planned excavation work.

11. At Site 15, the stream diversion systems cannot structurally modify the existing riser. The riser must continue to operate normally during construction.

12. The downstream embankment soils are anticipated to be wet of optimum. The contractor is responsible to utilize these soils by separating, drying, stockpiling, and providing moisture control for wet, saturated, and dry soils for reuse as Earthfill within the project activity time requirements. Reference CS21.

13. Regarding restoration of Staging Areas that have been regraded for the contractor’s operations. Following removal of any temporary geotextile, crushed stone, or other aggregate surfacing, staging areas that were graded to suit the contractor’s operations shall be restored to approximate original conditions/slopes prior to restoration with topsoil, seed, and mulch. The contractor shall include initial ground surveys for staging areas before excavation commences, reference CS 8.

Revisions / Clarifications Page 4 of 4

14. In regard to the installation of stream diversion components and cofferdam materials placed in the reservoirs. All stream diversion system components, including cofferdam materials, must be removed after it has served its purpose. Reference CS11, bid item for Stream Diversion for each site.

15. The purpose of the Site 15 CS402 Diving specification is to provide the contractor a means to inspect the riser drain gate and other riser features below normal pool to prepare for and order materials necessary to complete the upstream work within the project time requirements. Note - It is estimated that 6 to 9 feet of sediment is present around the Pond Drain Gate. The contractor is responsible for verifying the volume of sediment to move in order to inspect the drain gate and perform the work. Underwater work to install the drain gate or other components is not permitted.

16. There is a clarification for the excavation and earthfill bid items for Site 14 and Site 15. For Site 15 Bid Items 10, 11, and 12 have been modified. For Site 14 Bid Items 11, 12, 13, and 14 have been modified. These items have been updated to account for the removal of topsoil that is accounted for in Bid Item 15 on Site 15 and Bid Item 17 on Site 14. In regards to Specification 21 – Excavation for both Sites, there is no change to the specification. To clarify the removal of topsoil should be considered a “construction operation” in accordance with Measurement and payment Method 3, establishing the upper limit as the modified ground surface after removal of topsoil.
