Date of Report: October 11, 2025
Recent Activities:
Since the last Report on September 12, 2025 —
Sundt recoated the upstream crest plate in Bay 2.
The testing of infrastructure/components impacted by the free-fall incident in Bay 2 was completed.
Cathodic protection testing was completed.
The north embankment concrete roadway was started.
Work on Bay 2 side seals has continued.
Work on the side seals in Bay 1 was started.
Work on the maintenance bridge handrail, ladders and stairs continued.
Electrical and instrumentation work in the Powerhouse continued.
The stop log dry fit was completed.
North and south embankment concrete armoring continued.
Work on utilities and electrical on the south embankment continued.
Change Orders:
Approved Change Order: GBRA approved the Change Order that addressed minor required electrical modifications in the Powerhouse. This approved Change Order resulted in an increase of the Contract in the amount of $8,572.89, with no additional days added to the Contract.
Pending Change Order: Additional time is being requested by Sundt. This request was submitted for review and pending discussion with Black & Veatch and GBRA.
Testing and Schedule:
Testing: All testing associated with the free-falling event involving the gate in Bay 2 has been completed. The damaged concrete underneath the top anchor point of the southern most hydraulic cylinder was chipped out and replaced with high strength, low shrink grout. The seven (7) day curing period for that grout has concluded and Sundt is initiating the testing of the Bay 2 gate. Sundt’s pre-testing plan has been submitted to Black & Veatch for approval, and testing is expected to commence next week.
2. Schedule: GBRA and Black and Veatch had requested Sundt to review and revise its project schedule to provide best and worst case scenarios. At the October 9, 2025 Construction meeting, Sundt shared that (1) in the best case scenario Substantial Completion will be November 29, 2025; and (2) in the worst case scenario Substantial Completion will be in January 2026.
NOTE: With approved change orders to date, the Substantial Completion Date for Lake Placid is November 29, 2025*. It is important to remember that the Substantial Completion Date does not take into account the time needed to impound water to Lake Placid nor the final testing of the gates (as the lake has to be full in order to conduct the final testing). We expect impoundment to commence immediately following the Substantial Completion Date. [“ * ” See Item 2 under “Testing and Schedule”]
Upcoming:
In the next several weeks, we expect (1) Bay 2 crest gate testing (see “Testing” above); (2) pour back of the side seals (pour concrete behind the seals); (3) final torque tests on all bolts; (4) grouting of hinges, trunnion, and dogging arm pads; (5) cut Bay 2 cofferdam sheets; (6) route hydraulic tubing to Bay 1 cylinders; (7) installation of stop logs in Bay 1; and (8) continuation of remaining north and south embankment dam armoring, concrete placements, and rock riprap installation.
Substantial Completion Date: November 29, 2025*
NOTICE:
Notwithstanding the revised Substantial Completion Date announced by the contractor, as of this Report approximately forty-nine (49) days remain until we can expect water impoundment to begin at Lake Placid (i.e. November 29, 2025). Waterfront property owners along Lake Placid are reminded and encouraged to:
(1) remove all temporary docks, platforms and/or other structures that may have been placed at or below the normal operating level of Lake Placid in proximity to the riverbed since October 2021, and
(2) abate and remove all woody vegetation from the waterway in front of their property.
Once water is impounded behind Lake Placid Dam, removal of these items will become very challenging, if not impossible.
Note: The normal operating level of Lake Placid is defined as 497.5 feet above mean sea level at Lake Placid Dam, which is the historical operating water level.
