Please clarify work requirement. Bid Item 0008 Section Bidding Schedule requires replacement of 60" diameter flange.It appears to do this, it will require chipping concrete back near the flange bolts to cut the embedded cast iron pipe behind the flange. Place new 60" diameter flange and weld cicumference. Please clarify the connection between the round flange and the square thimble/frame for the sluice gate.

Government Response. . The exact orientation of the pipe flange, gate frame, and concrete is unknown until the draft tube is unwatered. The original construction specification, see "discharge pipe" in the attachment, states the downstream flange should be accessible to permit removal of the gate, how much is accessible upstream into the pipe is the unknown.

Does this project contain any lead abatement? I.E. does the existing paint contain lead?

What is the water temperature? Does the operating schedule of the dam allow for cure time of the paint?

On: Aug 11 2017.

Government Response. . The existing paint is coal-tar epoxy in accordance with the original construction specifications (see attachment). The draft tube gates will be isolated from both up and downstream pools, refer to 01 14 00.00 46 - 1.6.

7104738 Civil General General 01 14 00 para. 1.4, 1.4.3 Comment Classification: Unclassified\\For Official Use Only (U\\FOUO)

Work Restrictions--I understand that no work will be allowed from March 01 to May 31 in the spillway. Is the draft tube (sluice Gate) area considered part of the spillway? Para 1.4.3 dictates that no outages are to be performed between June 15 to September 15 and December 15 to March 15, Please clarify that work can be performed during the months not listed above.

On: Aug 11 2017.

Government Response. . Yes, the draft tube is in the spillway/tailrace. The dates stated in 01 35 13.01 10 are for flood control purposes to allow the Government, if necessary, to spill water from the dam into the downstream river (spillway/tailrace/river). Generator outage restrictions in 01 14 00.00 46 - 1.4.3 are for the "main generators", as stated in the fourth sentence, to allow the Government to produce electric power during periods of high demand. For example, if the contractor proposes to use divers in the spillway and requests reduced flows to facilitate the dive (i.e. generator outage), the contractor is encouraged to plan the dive outside of the periods stated in 01 14 00.
