PART 5 - EXECUTION 5.1 INSTALLATION

Gates and appurtenances shall be handled and installed in accordance with the manufacturer's recommendations.

5.2 INSPECTION AND TESTS

Perform the work in such a manner that when complete, it constitutes a complete, operational gate system. Perform installations shown on the plans. After completing the installation, subject the slide gate system to functional tests in the presence of the Owner/Engineer. Cycle each gate to confirm that they operate without binding, scraping, or distorting. The effort to open and close manual operators shall be measured, and shall not exceed the maximum operating effort specified. Electric motor actuators shall function smoothly and without interruption. Repeat the test as many times as necessary to secure a properly tested working unit. The Contractor shall be responsible for the coordination of the tests of each slide gate and valve with operators, in the presence of the manufacturer's factory service representative and Owner. Any leakage in excess of the allowable specified shall be corrected and the equipment retested until found satisfactory.

After the above described tests are complete and before acceptance of the work under this item, furnish the Owner/Engineer certificates from the respective manufacturers, guaranteeing the equipment against defects in material and workmanship for a period of one year starting from the date of the acceptance. Furnish the Owner/Engineer certified statements from the manufacturers or their authorized representatives that the installation has been thoroughly inspected by them and that it is in accordance with the Engineer’s design.

An inspection of work under this item will occur at the end of a 12-month performance period beginning after the work has suitably passed the required tests. The inspection will be conducted on a walk-through basis by the Owner’s/Engineer’s representatives in the presence of the Contractor or appointed representative of the Contractor. The Contractor shall correct any defects due to quality of workmanship or materials, and any work not in accordance with the plans and submittal, at no expense to the Owner at any time within the 12-month performance period.

12. Should Contractors assume that rutting and wet areas will remain after tree removal?

Response: The Owner’s tree clearing and removal contractor will provide the necessary E&S controls and rough grading of disturbed areas upon completion. However, the Owner makes no representations as to future soil moisture conditions within the Limit of Disturbance area.

13. When does the Owner anticipate awarding the contract within the one-hundred and

eighty (180) days bid acceptance period? Response: Owner understands that time is of the essence. It will award the contract when project permits are issued. Extensions beyond the bid acceptance period will require the written approval of the prospective Contractor. Bid securities will be returned expeditiously to Bidders with non-competitive bids as determined by the Owner.

16. Is the Contractor required to provide a Road Bond and if required, what is the amount?

Response: Upon further inquiry, no Road Bond is required by WVDOT. 17. Note 1 on Sheet No. 6 states that the Contractor is to “provide 1 ½”min. thickness after

compaction WVDOH hot mix asphalt wearing course overlay to the limits shown on plan and profile sheets.” Where are the limits shown on the Drawings? Response: Reference Sheet No. 87 of the Drawings for pavement overlay (Sta. 1+00.00 to Sta. 1+78.00; with the limits shown on the profile sheets).

18. Will an additional payment item in the Bid form be considered for excavation and

placement of the borrow areas? Response: No modifications to the Bid form will be made for any work related to the borrow areas. All borrow area-related work shall be included as a subsidiary cost for various earth dam embankment materials per Section 01 20 00.

19. When does commencement of the 180-day dam embankment placement period begin?

Response: Upon approval of the prepared dam foundation by the Owner, Engineer and WVDEP Division of Dam Safety, the placement period will begin on the first day of earth fill placement on the approved dam foundation by the Contractor.

place period?” Response: No, the cofferdam installation is a separate construction operation.

21. Define the “lowest, responsible and qualified bidder” relative to bid award.

22. Is there enough clay on site for the planned work? Response: Sufficient quantities of various embankment materials are available from borrow areas within the Limit of Disturbance as shown on the Drawings. Reference the project Geotechnical Report for logs and photos of previous test pits. Test borings are available for inspection at the office of the Owner. The Bidder may perform exploratory excavations per Article 4 of Section 00200: Instructions to Bidders.

23. What is the required drawdown rate for Cobun Creek Dam No. 1? Response: The Owner will lower the reservoir to the levels indicated on the Drawings. As noted in the Appendix, reservoir drawdown levels are limited to one (1) foot per day). However, the outlet capacity of the dam is limited and the Owner cannot control reservoir levels in high stream flow conditions. The Contractor should consider these risk factors and schedule the spillway work during seasonal low flow conditions.

24. Will borrow areas will also be cleared of trees by MUB?

Response: The Owner will clear and remove all trees within the Limit of Disturbance which will include proposed borrow areas.

25. Does this modify the quantity for clearing and grubbing of borrow areas?

Response: All trees within the Limit of Disturbance will be cleared and removed by the Owner which would encompass potential borrow areas. The Contractor will be required to perform grubbing (including stump removal and disposal) for that portion of the Limit of Disturbance required for borrow areas. As such, no separate payment will be made for grubbing of borrow areas. Payment of grubbing is strictly limited to the grubbing boundary delineated on Sheet No. 12 of the Drawings (reservoir, dam site and access roads). Tree clearing and removal will be addressed in an Addendum.

26. Is on-site disposal of stumps acceptable?

Response: Stump disposal will be modified by Addendum (Section 31 11 00 Clearing and Grubbing, Paragraph 3.6 - Disposal of Materials)

27. How much of each tree will be left upon the conclusion of MUB’s tree removal? Response: Trees will be removed to within one (1) foot of the ground surface. Tree clearing and removal will be addressed in an Addendum (Section 31 11 00).

28. Clarify requirement for excess topsoil to the Owner.

Response: Upon further consideration, the entire Limit of Disturbance is available for stockpiling of topsoil and the Contractor shall utilize these areas within the context of its material storage and handling plan. The matter of excess topsoil removal by the Owner will be addressed in a future Addendum.

30. Can excess material from Cobun Creek Dam No. 2 be used at Dam Cobun Creek Dam No.

1, and vice versa? Response: The provision for earth embankment materials at either dam is the Contractor’s responsibility.
