SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

REQUEST FOR INFORMATION

1. What type and viscosity of hydraulic oil is used ? Are we supplying the “top off” oil – Response: There have been two types of hydraulic fluid added to this system. One fluid is a Duralene ZD AW 32 hydraulic oil and the other is a Travellers AS Hyd ISO46 hydraulic oil. The contractor will be responsible for topping off the system after it is re-assembled.

2. Does the filtered oil have to be sent off to prove it is 10 microns or less? Or will filtering with 10 micron filters suffice.

Response: Contractor shall top off the hydraulic tank with hydraulic fluid as specified and actuate the oil filtration system with a 10 µm element in the filter. Circulate the fluid and change filters as they become clogged.

3. What is the operating pressure of the HPU?

Response: The maximum operating pressure of the system is 500 psi.

4. Has the lifting beam in the gate house been load tested?

Response: Yes, the lifting beam was load tested when the new the trolley and hoist were installed.

5. Please provide a photo of the counterbalance valve on each slide gate. – Response: No longer included in scope. Revisions to scope will be issued in subsequent amendment.

6. Please provide technical description and mfg. part # and drawing for the counterbalance valve. – Response: No longer included in scope. Revisions to scope will be issued in subsequent amendment.

7. Millwrights will perform this work. Can you provide Davis Bacon Rates?

Response: Wage Determinations are included in the solicitation that cover the majority of work. Millwrights would be covered under Service Contract Act Wage Determination #2015-4023 for Merrimack County, New Hampshire.

8. We can machine the polyurethane part of the seal out of a 55D material, but the spec for the rubber energizer is saying 85D, which is harder than the sealing element. We would only be able to machine the energizer from 85A NBR. Is this just a 2pc seal? The description b. on drawing m-301 references cap seal and often times that is a 4pc piston seal.

Response: The proposed design shall utilize a 2pc seal. Contractor may submit alternative materials for review after contract award.
