and 010-G-

Can you clarify the sources of the temporary flows called out in the Process

Flow Diagrams?

Flows 3 and 5 into Primary Clarifier 1 as shown on 010-G-022: These are

an existing 15" TOF (may also be labeled TUF) and 8" UD that run south of aeration basins 1 and 2 as shown on sheet 050-CY-109 where they are identified by note 7. Temporary pumps are to be installed in Primary Clarifier 1 to pump these flows into aeration basins 1 and 2 as shown on that sheet. Temporary Trickling Filter Effluent pump station and Secondary Clarifier 2 Effluent Bypass to Aeration Basins 1

and 2 as shown on 010-G-022: This piping is shown on 050-CY-108 (notes 7, 8 and 9), 050-CY-109 ((note 11), 050-CY-113 (notes 1 and 5) and 050-CY-114 ((notes 8, 9 and 10). Aeration Basin 1 and 2 Underdrain Piping as shown on 010-G-023: This piping is shown on 050-CY-109 (note 9) and diverts the underdrain pump station discharge into aeration basins 1 and 2.

19 The steel fabricator would like to confirm that you want cement lining on the air piping. The reason for his asking is that the air will dry out the cement causing it to break and fall off which could possibly cause serious problems in the air system. Normally what they see is no lining and primer coated. Please let me know what you would like.

See Addendum 4.

20 Is there a domestic material requirements

for this project? We have not been able to find anything in the specs.

This contract does not include

domestic materials requirements.

21 050-CY-109 The TOF line. Per the piping schedule this is called out as Cement Lined Ductile iron pipe. The drawing calls it as 15", could you clarify is this pipe indeed Ductile iron, if so is it 14" or 16" (15" DI not made) or is it 15" C3034 sewer pipe?

See addendum 4

22 423-M-301 Valve Tag V202 appears on sheet 423-M-301 but is not defined in the valve specifications. Please specify the valve required at this location.

See Addendum 4.

23 321-M-11 Drawing 321-M-111 indicates that the existing Trickling Filter Mechanism is to be removed and turned over to the Owner. 1. To what extent is the mechanism be

broken down to. 2. Location of where the mechanism is to be delivered to.

See Addendum 4

25 371-E-111 The only pole lighting I have found is at Aeration Basin #3, P2's and P3's. Are there some I didn't see maybe on the site Drawings?

Two P1 luminaires and poles are shown on drawing 371-E-111 to illuminate the Primary Effluent Pump Station.
