Would restrained joint pipe and fittings restrained by wedge action restraints be acceptable instead of thrust blocks and threaded rod?

Response: See Addendum 1

Question 7

Posted: 1/11/2024

Question: Sheet 12, Thrust Blocking Sheet 4 of 4 provides thrust blocks based on 150 PSI. Specification 02660, 3.10 calls for 150 PSI Test pressure, but Sheet 10 Rodding Restraint Detail lists 250 PSI Test Pressure. Please confirm test pressure is 150 PSI. If not please revise or confirm thrust block details are still appropriate.

Response: See Addendum 1

Question 8

Posted: 1/11/2024

Question: Sheet 12, Thrust Blocking Sheet 4 of 4, Note 2 states “The water line must be lowered in order to have five feet (5’) of cover at the bend, tee, reducer or plug at all locations where these fittings may be utilized”.

Response: See Addendum 1

Question 9

Posted: 1/11/2024

Question: Sheet 12, Thrust Blocking Sheet 4 of 4, Note 3 states “The contractor has the option to use restrained joints in lieu of or in addition to concrete blocking as specified in section 02660 of the specifications” but the specifications are silent on restraint, and Sheet 6, Note 4 states “Thrust Blocking Required At All Bends”. Please confirm if restrained joints are provided the thrust blocks and rodding are not required.

Response: See Addendum 1

Question 10

Posted: 1/11/2024

Question: In 2.0 Scope of Work, paragraph 2.2 states “On Site testing of the soil compaction is required.” The documents don’t discuss who pays for this testing. It is standard for the Owner to pay for third party testing of soils, concrete, masonry, etc. Please confirm testing (including soil, concrete, and masonry) will be paid for by the Owner.

Response: See Addendum 1

Question 11

Posted: 1/11/2024

Question: Drawing 6 & 7 have no scale or dimensions. Please provide a scaled drawings or dimensions on the drawings to determine the scale.

Response: See Addendum 1

Question 12

Posted: 1/11/2024

Question: Sheet 3 calls for a 15’x20’ well house. Since the drawings are not scaled is the foundation slab size 15’x20’, or is that the outside wall dimensions, or inside wall dimensions?

Response: See Addendum 1

Question 13

Posted: 1/11/2024

Question: The drawings are unclear on the buildings material of construction. Sheet 13 has both 2x4 Stud Wall and CMU Wall details. Sheet 14 shows the well head roof framing plan with CMU called out. Please confirm the Well House is the 2x4 Stud Wall Construction Detail, and the Well Shed is the CMU Wall Construction Detail. If not please clarify.

Response: See Addendum 1

Question 14

Posted: 1/11/2024

Question: Sheet 3 calls out “2” DIP Drain to Daylight (Bottom of 16” Pipe)” and “2” DIP Blowoff to Daylight”. a. 2” DIP is not made, what material should be used? b. The note says “drain to daylight” (and “to daylight”), however the pipe doesn’t appear to be long enough to daylight based on pipe depth and grade contours. Specification 02660, 3.01 requires the cover of the 16” pipe to be 48” making the invert ~65” deep. Average finished grade elevation is 876, so invert ~870.58, but the end of the drain/blow off pipes are around EL 875. Daylighting the pipes are outside the limits of disturbance. Should the 16” Pipe depth of cover be reduced to allow the drain pipe to daylight, if so to what? If not please provide direction on how to address the drain elevations and daylighting issue (possibly consider removing to daylight requirement and providing different detail at end of pipe to allow a temporary submersible pump to be used when draining is needed since likely infrequent).

Response: See Addendum 1

Question 15

Posted: 1/11/2024

Question: Sheet 10, the top of the page “Pipe Support” detail requires 1/8” thick insulation material, but this will require custom U-bolts due to the non-standard pipe OD. It is uncommon to install an insulation material on Ductile or Steel pipe (typically only used for copper pipe to provide dielectric barrier). Please confirm the insulation material is not required to avoid unnecessary additional cost and lead times.

Response: See Addendum 1

Question 16

Posted: 1/11/2024

Question: Sheet 7 has a note “Chemical Line” but points to a blank area. Please clarify if additional chemical piping is required that is not shown.

Response: See Addendum 1

Question 17

Posted: 1/11/2024

Question: Sheet 7 has a note “Chlorine Injector (See Note 16)”, and “Chlorine Analyzed Intake (Note 18) but there are no notes on this drawing. Please provide missing notes.

Response: See Addendum 1

Question 18

Posted: 1/11/2024

Question: Please confirm the chemical tanks size, material, and concentrations as they vary from drawing to drawing. Sheet 15 mentions polyethylene, is this for all chemical tanks? Sheet 7 mentions drums. Is the contractor to supply all the chemicals? Owner may want to consider using chemical totes instead as these can be moved by pallet jack and exchanged easily through roll up door. a. 2 EA – 30 Gallon Chlorine (12.5% Sodium Hypo) b. 1 EA – 100 Gallon Fluoride c. 1 EA – 50 Gallon Caustic

Response: See Addendum 1

Question 19

Posted: 1/11/2024

Question: Sheet 6 only shows the Chlorine tanks connected to the piping. Are the Fluoride and Caustic for use by the Owner as needed (used manually). Note that Specification 01025, 3.06 mentions chemical feed system for Sodium Hypochlorite and Fluoride), and no chemical feed is shown for Fluoride. Please confirm drawings are accurate and no piping or pumps are needed for Fluoride and Caustic.

Response: See Addendum 1

Question 20

Posted: 1/11/2024

Question: Sheet 6, Note 13 calls for 1” PVC pipe to be installed along pump column for level transducer installation. Sheet 13, Well Casing Stub Up Detail shows a ¾” PVC pipe extending down into the well. Sheet 11 shows a wire and associated level transmitter but no conduit. Please confirm when the conduit terminates.

Response: See Addendum 1

Question 21

Posted: 1/11/2024

Question: The Bid Form includes item #7 “SMART System”, however there is nothing in the documents to determine the scope of this work. Please provide drawings or specification on this scope.

Response: See Addendum 1

Question 22

Posted: 1/11/2024

Question: Specification 01025, 3.10 Access Drive states the access driveway/parking is GAB/crushed stone over the 16” pipe area. The limits of the stone are unclear, is the GAB/crushed stone to extend from back of curb (Revere Drive) to the Western edge of the Well Shed, and from 16” C/L to C/L in North/South direction? Please clarify intended limits. Please also clarify that Specification 02510 Asphalt Pavement and 02520 Concrete Paving are not applicable on this project.

Response: See Addendum 1

Question 23

Posted: 1/11/2024

Question: Sheet 6 calls out a 4’x4’ Concrete Landing. Sheet 3 also appears to depict a larger concrete landing South of the Well House (at roll up door). Is a concrete landing required at the roll up door per size scaled on Sheet 3? What are the concrete landing requirements (6” thick with WWF reinforcing?)

Response: See Addendum 1

Question 24

Posted: 1/11/2024

Question: 180 Days project duration will be difficult due to some material lead times being 12-16 weeks. Please consider revising the project duration to at least 270 days. It is possible named suppliers may have longer lead times which may require an even longer project duration than requested, but it is unknown at this time if that will happen. Please note that in the Bid Proposal Form on the page with the LUMP SUM ALLOWANCE AMOUNTS, 150 days is listed which is in conflict in earlier pages of the Bid Proposal Form.

Response: See Addendum 1

Question 25

Posted: 1/11/2024

Question: Is there any specification or parameters required for the Silent Check Valve or Diaphragm Valve?

Response: See Addendum 1

Question 26

Posted: 1/11/2024

Question: Sheet 6 calls for 2” DIP (which is not made) and 6” HDPE, but Sheet 3 calls for 6" to be PVC. Please confirm both 2" and 6" pipes can be PVC.

Response: See Addendum 1

Question 27

Posted: 1/11/2024

Question: Specification 02200, 3.10 requires general fills and backfill to be compacted to 95%, however it goes on to say “Cut areas shall have the top six (6) inches of material proof rolled and compacted to 100% of maximum density. Fill areas shall have the top twelve (12) inches proof rolled and compacted to 100% of maximum density.” It is uncommon to require compaction of 100% except for special circumstances. Requiring 100% compaction on cuts will likely require extensive work to the existing soil which will greatly increase cost and schedule duration (extremely unlikely any existing onsite soils are 100% compaction). Requiring 100% compaction on fills for the top 12” would not allow for grassing and greatly increase cost and schedule duration. Sheet 4, Note 6 is a more appropriate/typical backfill requirement. Please confirm the 100% compaction requirement is not required on this project, and cuts do not require compaction. It is typical that if a cut’s subgrade is not sufficient or is unsuitable it is over excavated under the direction of the Engineer (or Geotechnical Engineer) and paid as a change order/allowance. Please confirm if this is how existing soil/subgrades will be handled.

Response: See Addendum 1

Question 28

Posted: 1/12/2024

Question: I see no allowable manufacturer for a chemical feed system as a whole. I also do not see allowable manufacturers for components of one should the intent be that we are building one within the building by way of holding tanks and pumps. Please clarify the intent and where I can find allowable manufactures for this portion of the job. Please clarify the chemicals to be used for this portion of the work as well, as the specs read in a contradictory manner.
