7. SECTION 15129 – Couplings and Connectors Added the new Section 15129.

Questions and Answers: Question 1: RAS AND AIR PIPING LAYOUT : Drawing M – 9 is showing the RAS and the Air

supply pipe running along the sides of the MBR Basin and the Oxic Tanks. The plan view only shows the stainless steel air line along the side of the MBR

of 28


basins. The RAS appears at the left side of the IRQ pumps where it turns and goes into the Oxic Tanks. We are trying to determine the length of the run of RAS pipe from the MBR area down to the Oxic tank. Checking the location of the new air line going into the Oxic tank we measured a distance of 70 feet from the corner of the MBR basin – 01, to the flanged 90 bend turning up and into the Oxic tank. We scaled the drawing to be 1/8” per foot as indicated. The section view – C , which is shown on drawing M – 14, shows both the RAS line and the Air line. We measured the distance from the right corner of the structure, which should be the MBR – 01 basin, down to the flanged 90 bend in the air line, and it measured 85 feet. This is based off of the 1/8 “ scale indicated under the section –C, heading . We are wondering if there is a problem with the scale references between these to views of the Air and RAS lines. We want to make sure we get the distances correct for these two lines. Please review and clarify these pipe layouts.

Answer: See revisions to Sheet M-14. Question 2: HEADWORKS – DRAIN PIPING : Drawing M-3 is showing the 3 “ and 6 “ PVC

drain pipe which is under the second floor level deck. The three inch line is shown to be connecting to the Shaftless Screw Conveyor on the deck above. The line is shown extending all the way to the 6 “ PVC pipe on the east side of the structure. Looking at section – B on sheet M-7, it is showing a 3 “ PVC drain line coming off of the Rotary Drum Screen on the upper deck. There are two of these units. We do not see these two drain lines on drawing M – 3. Please review and clarify where these two 3 “ drain lines are to be routed below the upper level deck.

Answer: Section B on Sheet M-7 shows the drain line from the Shaftless Screw Conveyor

as shown on Sheet M-3. Question 3: HEADWORKS – COMPOSIT SAMPLER : Drawing M – 3 is showing the

Composite Sampler at the south east corner of the structure on the first floor level. We are considering that the first floor level is the ground floor of the structure. The drawing is showing a composite sampler drain at the column on the corner of the structure. The note on the drain line states “ 3 “ PVC drain above “ . It seems to be indicating that the sampler is on the upper level deck. If the sampler is on the ground floor level , then the drain line cannot be up under the upper level deck. This sampler location and drain line need to be reviewed and clarified.

Answer: See revisions to Sheet M-3. Question 4: HEADWORKS – DRUM SCREEN DISCHARGE LINE : Drawing M – 4 is

showing the two Rotary Drum Screens on the upper level deck.

locations at the Headworks Structure where 1 “ and 2 “ diameter stainless steel pipe is shown for Plant Service Water and Sample lines. We looked in the specification section 15060 – Exposed Piping and Fittings and did not find a specification description for the stainless steel pipe. We did find specification section – 15066 – Stainless Steel “Air “Pipe and Fittings. Are we to use the section – 15066 for the stainless steel piping for water and sample lines? Please review and clarify.

Answer: Yes, Spec Section 15066 should beStainless Steel Pipe and Fittings. Question 15: RAS PIPING LAYOUT : Drawing M – 14 , section – C, is showing the 14 “ RAS

pipe extending along the outer wall of the MBR basin. Note that the section view appears to show the RAS line with a flanged 90 bend at the corner of the MBR basin tank wall. Looking at the RAS piping as detailed on drawing M – 21, it is showing the RAS line approximately four feet away from the corner of the MBR basin tank wall. Should the configuration shown in section – C be revised or corrected to show the RAS pipe as drawn on sheet M – 21? Please review and clarify.

Answer: See revisions to sheet M-14 Question 16: RAS PUMP PIPING : Drawing M – 21 is showing the piping connecting to the

RAS pumps. There is a callout for an item marked – 19. The description of this item is “ 10 “ D. I. P. Flex – coupling, FLG. “ . The RAS piping has been cross hatched so it does not show the pipe and this item clearly. We can’t tell exactly how it is drawn to determine exactly what it is. Our first impression of this item is that you are meaning for it to be a Flanged coupling adapter. But then it could be that you want it to be a flanged flexible rubber expansion joint, with a single filled rib. We are not sure. Please clarify what is required for this item – 19.

Answer: Item 19 shall be a flanged flexible rubber expansion joint. Question 17: FLANGED RUBBER EXPANSION JOINTS : Looking in specification section –

15080 – 2, 2.01, B – Rubber Type Expansion Joints, we find the description of flanged rubber expansion joints. We see that a temperature rating is indicated for the joints, but we do not see any reference as to a pressure rating. Do the expansion joints need to withstand a certain vacuum rating ? We will also need to know how much of an offset the joints will have to provide. And we will need to know how much compression or elongation the joints will have to handle. We will be asked these questions by the manufacturers when we contact them for

We do not find any reference as to how many arches are required. Looking at the Permeate piping on sheet M – 20, the flanged rubber expansion joints are drawn as if they are double arches, such as a Mercer style 452. Please review and clarify how many arches are required for these flanged expansion joints.

Answer: Double arches are required. Question 19: KNIFE GATE VALVES : Specification section 15100 – 34, 2.03, C, Knife Gate

Valves, states in paragraph 1, that “ wafer type is not acceptable “ . Then in paragraph 2, it says that “ knife gate valves shall be water type “. We assume that this is a typo and that it meant to read “ wafer “ . Please review and clarify what type of body type is required for the knife gate valves.

Answer: See revised Section 15100. Question 20: RAS PUMP PIPING : Drawing M – 21 is showing the piping connecting to the

RAS pumps. The vertical pump discharge pipe is showing an item – 42, which is described as being a ” 10 “ isolation valve “ . We believe these valves are being supplied by the process equipment supplier. Looking at the way the valve is drawn, we can’t tell if it is a knife gate valve or a butterfly valve. We need to know if it is a wafer body valve or a lug style valve. We need to know what type of bolt and gasket set to provide for these valves. Please review and clarify.

Answer: This is supplied by the process equipment supplier. Question 21: BIOLOGICAL PROCESS TANKS PIPING: We have been reviewing the

drawings for the different process systems piping. We note the different pipe and equipment shadings for Overhead Air Piping, RAS /WAS Piping, Permeate Piping and equipment furnished by OVIVO. We are trying to determine what pipe OVIVO will be providing, if any at all. We have not found any notations or comments on the plans. Will they be providing any piping inside the process tanks or basins ? Please clarify if OVIVO will be providing any of the piping for these systems.

Answer: Ovivo will not be providing any piping. Question 22: MARK ITEM NUMBERS : Drawing M – 18 has several miscellaneous sections

Answer: No. The City will not provide a list of items for the Unit Price Bid Form. Question 56: Section 00900 states that the Owner will pay for all calls outside of the local area,

but section 01520 states that the Contractor is responsible to pay for all calls without reimbursement. Please clarify what the Contractor is responsible for.

Answer: Please refer to the revised Sections 00900 and 01520. Question 57: Are there any mandatory minority participation requirements? Answer: Please refer to the FDEP Supplementary Conditions in the Specification. Question 58: A bid bond is not provided in the bid form. Will the standard AIA bid bond suffice? Answer: Please refer to the “Security Bond” in the “Invitation to Bid” for the bid bond

requirements.
