Revised 4 June 2001 PM Don Getty
A. PROJECT DESCRIPTION
Kentucky Lock is located in western Kentucky at Mile 22.4 of the Tennessee River. A feasibility report completed in 1992 recommended a new 110' x 1200' lock adjacent and landward of the existing 110' x 600' lock. The project was authorized for construction in WRDA 96 and construction commenced in July 1998. Based on an expected funding level of $25.2M (Appropriated $30M minus Savings & Slippage), our FY 01 spending plan is provided below:
$ 4.5M In-house design and management $ 1.2M Other Corps $ 0.5M TVA in-house $ 7.5M A/E Contract Design $11.5M Construction and Real Estate Acquisition.
B. GENERAL Significant activities, issues raised, and decisions made during the month on the project include :
·
Upcoming Construction
Contracts Our plans to
initiate four construction contracts within the next few months are on
track. The two large
contracts, the Upstream Cofferdam and the Bridge Piers, are scheduled for
advertisement in late June. The
Construction Field Office and the Wetlands at Benton are planned to be
negotiated contracts that should be issued in the July/August timeframe. Construction activities: · TVA Transmission Towers The third of four tall east bank towers is nearing completion. · West Bank Hwy/RR Embankment Murray Paving continued significant construction activities in May. This $5.9M contract is approximately 22% complete and ahead of schedule. C. PROGRESS FOR THE MONTH: Environmental · Draft Supplemental Environmental Impact Statement LRD has concurred that the ROD can be signed by the Division Commander. Also, LRD forwarded the FSEIS to the US EPA for filing on 31 May 2001. The earliest expected ROD signing date is now 9 July. · Wetland Mitigation - The 90% P&S package is still under review. A construction contract is planned to be initiated this summer. · Mussel Mitigation The underwater survey work for Kentucky Lake is about 80% complete with over 70 of the 94 sites finished. · Tailwater Fishing Mitigation The scope for the west bank fishing jetties has been agreed upon by all four agencies involved. Construction of the jetties is anticipated to commence as soon as possible after the FSEIS Record of Decision is signed. A mussel relocation effort of the jetties footprint is required prior to the start of construction. WES Navigation Model Status A draft final report is currently under review. WES Lock Model WES plans to reactivate this model with the new upstream middle wall configuration in May. We will be investigating the affects of this configuration on the thru-sill filling system. Lock Design In-house. The main focus of in-house resources is to manage A/E contracts and initiate the new construction contracts mentioned in section B above. Work is continuing on the geotechnical drilling program, the support of WESs Lock Model work, new lock stability, existing lock lower land wall stability, miter gate design, lock intake trashrack design, the Materials DM, and the east bank permanent embankment. Electrical/Mechanical Design. The 95% submittal of this DM was delivered approximately 15 May. In-house review will be completed in June and the Task Order completed this summer. Upper Approach Walls The 90% submittal of the Phase 1 Design Report was delivered in May. If needed, a comment resolution meeting is tentatively scheduled for 12 June. A delivery order to ARCADIS to perform over water drilling at the new middle wall nose pier location was awarded in May. This work will be performed during the June 5th through June 25th closure of the existing lock for maintenance so it can be accomplished without affecting navigation traffic. Miter Gate Design. Louisville District is continuing work on the Plans & Specifications for this feature and is approximately 90% complete. Details of the finite element analysis are being refined to correct stress concentrations in the lower girders. Louisville is finalizing operating strut attachment and bridge details for a P&S check by INCA. Site Utilities The 70% submittal is expected in mid to late June, with the final report completed by the end of the fiscal year. Site Seismic Criteria The final submittal on this report is expected from Harza any day. Upstream Monolith Design The 30% submittal for this task order has been delayed due to complications encountered during seismic stability analysis for the monoliths. Unusually large monolith widths were required using the planned method of analysis. Black & Veatch has been working with the Nashville District and USACE to determine the appropriate method of analysis to be used. The request for proposal to modify the Black & Veatch task order to reflect the agreed upon method of analysis has been sent and the proposal is expected by 1 June. Downstream Lock Design - Huntington District is continuing work toward a 30% DDR submittal this FY. The conditions encountered in the upstream design referenced above is likely to affect Huntingtons work. Demolition and Modification of Existing Operations Building Comments for the 70% submittal of this design were forwarded to Harza in early May. If needed, a comment resolution meeting will be held June 14th. New Operations Building Award of the task order for P&S of this facility and the new Maintenance building is scheduled for early June. Since close coordination will be required with the East Bank Roadways/Site Plan effort, a joint kick off meeting is scheduled for June 13 and 14 at Barkley Resource Managers Office. East Bank Roadways/Site Plan P&S Efforts have been initiated to issue a modification to ACE to prepare P&S for the parking lots, roadways, and site grading for the east bank area of the lock. This will require close coordination with the two buildings being designed by Harza above. A combined kick-off meeting on these two efforts is scheduled for June 13. Transmission
Towers Construction progress See Construction Activities in Section B. Retaining wall for three downstream, east bank 69 kV towers Efforts are continuing to have TVAs Heavy Equipment Division perform this walls construction. A tentative start date for this construction is 2 July 2001. Disposal/Contractor Laydown Areas Vulcan Materials Disposal Site Comments on the 100% submittal have been delivered and a final submittal is expected by 8 June. Cofferdam
Design Downstream cofferdam The final submittal for Phase I design was received 23 May. The request for proposal to issue a task order for complete P&S has been sent to Bergmann/Gerwick.
Upstream cofferdam In-house efforts to prepare the construction contract solicitation package are continuing with advertisement anticipated in mid June. The CBD announcement for the solicitation was issued on May 1st.
East Bank Temporary Cut-off Analysis The 100% report was delayed due to higher priority work on the Blasting Report needed for the Bridge substructure contract. The final submittal for this report will follow completion of the Blasting Report. Materials DM WES is continuing testing on concrete mixes. We are still on schedule to issue an essentially complete report at the beginning of FY 02. Reports on some testing continuing past this date will be issued as an addendum to the report. Relocations · RR/Hwy Design · TN River Bridges Substructure P&S All elements of the design team submitted their final P&S to the Corps by the scheduled date of 11 May. A CBD Synopsis has been issued with an expected advertisement date of around 25 June.
