Addendum Items

I. Bidder Questions 1. Upon completion of the Fire Hydrant relocation, is the contractor required to pressure

test the system, and / or post sanitation testing?

The Contractor shall flush and test the relocated hydrants/lines according to the following: Flushing: Potable water shall be flushed through the for a minimum of 15 minutes or until no trace of cuttings, lead, oil, dirt, or other foreign matter is visible. Water shall be disposed of appropriately. All new piping shall be thoroughly flushed and washed prior to the time of sterilization. Pressure Test: A. Pressure Testing. Immediately upon completion of the water distribution system,

flush line in accordance with AWWA Standard C60L. All new pipe lines are to be hydrostatically tested before backfilling is completed. The test pressure is to be at least 100 PSI. The pipeline should be filled slowly and care should be exercised to vent all high points and expel all air. The test pressure shall be maintained for at least two hours and for such longer time as the Engineer may require. In preparation for the pressure testing the following minimum steps shall be taken:

B. All fittings shall be properly anchored. C. The Contractor shall furnish all materials, equipment and personnel for the test.

The pipe line shall be slowly filled with water and all air shall be expelled from the line. Care should be exercised to vent all high points and expel all air. Vents should remain open until water flows from them at a steady flow. After the air has been expelled and the valve or valves segregating the part of the system under test are closed, pressure is then applied by means of a hand pump, or gasoline pumping equipment for large lines. After the main has been brought up to test pressure, it should be held at least two hours and the make-up water measured with a displacement meter or by pumping the water from a vessel of known volume. If possible, the pipe and joints should be inspected thoroughly while under test pressure. Any leak or excess moisture at the joints should be reported and the line made tight.

D. No leakage shall be permitted.

2. How long will the Contractor be required to be present for the commissioning?

The Contractor will be required to be present for 7 business days, which may or may not be consecutive, and may fall outside the required construction completion time.


9/7/2010

3. Contractors raised concerns about disposal of excavated materials which may include coke materials.

All items indicated to be excavated, demolished, or removed, shall become property of the Contractor and shall disposed of off site by the Contractor in accordance with all applicable Local, State & Federal laws. Excavated materials may contain coke, which is not hazardous, but must be brought to a municipal landfill.

4. Will the removed tray be returned to the Port or become property of the Contractor?

All items indicated to be excavated, demolished, or removed, shall become property of the Contractor and shall be disposed of off site by the Contractor in accordance with all applicable Local, State & Federal laws.

5. What are the backfill and compaction requirements?

Backfill and compaction shall be as described in the specifications.

6. Will there be any boring beneath existing railroad tracks?

No boring will be required beneath or near existing railroad tracks.

7. Is there a specific panzer belt assembly that is acceptable?

See Panzer Belt Replacement Notes on S-200. 8. Will backfill compaction testing be required and who will be responsible for it?

Backfill compaction testing will be provided by a 3rd party, paid for by the Port. 9. On E-100 – should “New Ductbank 24” be “New Ductbank 23”? Section A shows

new ductbank, but is not cut where there will be new ductbank.

Correct, the note regarding the duct to the woodchip control house should refer to duct bank 23, and section A/E100 is cut in the wrong location. This has been corrected on the revised drawing.

10. Reinforcing steel in the new duct bank is not called out.

Reinforcing steel requirements are included in the revised specification. 11. The cable tray should have rolled edges to prevent wear on the outer insulation of

the power cable. 12. Contractors requested splice kit specs.

This has been included in the revised specification.


9/7/2010

13. Reporting requirements associated with testing.

Cable testing requirements are included in the revised specification.

14. Specify the cable tray.


15. Clarify the scope of Seimen’s project with respect to the scope of this contract.


II. Specifications

Remove and replace the previously issued specification section 16000 with the attached: Section 16000 - Electrical Installation For New Infrastructure To Support New Ship Unloader At Bt-1 Rev. 1

III. Drawings

1. The following is a generic description of changes to several electrical drawings,

regarding the routing of the new fiber from the ship unloader. The new routing for the fiber optic cable shall be from new Junction Box No. JB-BT1 on the dock, to manhole no. 3 and then from manhole no. 3 to the existing MCC located at the top of the junction (transfer) house. This new route will eliminate the new duct bank (i.e.,23) from manhole 3 to the wood chip control room. Instead, provide a four inch duct/conduit from manhole 3 to the MCC at the top of the junction house. Field route the conduit inside the junction box as required to enter the building on the north wall, and then route up to the I/O panel in the MCC.

2. Remove and replace Rev. 0 of the following drawings with the attached:
