ADDENDUM #2 A2- 1

ADDENDUM #2

June 11, 2024

ROUND HILL WATER SYSTEM

AIRMONT WATER TANK

1. The time and date for receipt of bids is unchanged at 2:00 PM (local prevailing time) on Tuesday June 18, 2024. It has been noted that the Town’s listing on the eVA website incorrectly notes the closing time. Please disregard this erroneous listing on eVA which has since been corrected.

2. The attached minutes of the Pre-Bid Conference held on June 4, 2024 are an integral part of the Contract Documents and are incorporated by reference.

3. The scope of work for the Town’s SCADA provider (Valley Automation) is attached. Reference Addendum #1 Questions and Clarifications #10 and Section 16010 Paragraph 2.7 for additional information. Bidders should coordinate with Valley Automation (Chris Smith, csmith@valleyautomation.net) to obtain pricing such that this work is incorporated into the lump sum bid price. The Contractor shall be responsible for coordinating the SCADA work, providing power for the SCADA panel from Panelboard A, and providing necessary panel mounting provisions that are best suited to the specific tank style.

Changes to the Contract Documents:

1. Replace Section 00410 – Bid Form, with revised Section 00410 attached. Article 3.01 was modified to clarify the Base Bid (composite style tank) and Alternate Bid (spheroid style tank), both of which are lump sum bid items for all work. Bidders may choose to provide a bid for the Base Bid only, the Alternate Bid only, or both.

A deductive bid item was also added for the Base Bid. The deductive bid item is optional. The deductive amount is the amount subtracted from the Base Bid amount to remove the overhead door and single personnel door from the composite tank and to instead provide a commercial double door similar to the one specified for the spheroid tank in Addendum #1.

(Note to bidders: For clarity, note that a deductive bid is not needed for the Alternate Bid (spheroid style tank) because the overhead door and personnel door were already replaced with a commercial double door per Addendum #1.)

2. Revise Section 02510 – Water Distribution as follows:

Add the following to Paragraph 2.1 – Materials:

10. Water Service & Meter: Provide a new water service, tapped from the 12” water line and located on the site as directed by the Owner during construction. The general arrangement of the service and the primary components are depicted on Standard Detail W-22. Water service and all components shall be per Town of Round Hill Water and Sewer Standards and the Loudoun Water Engineering Design Manual.

Standard Detail W-22 is included in this addendum showing the general components of the required water service; however, please note that per the Round Hill Water and Sewer Standards the Town does not allow flared copper connections and instead requires CTS compression mailto:csmith@valleyautomation.net

ADDENDUM #2 A2- 2

connections (A.Y. McDonald Type “G” grip style). The Town will provide the actual meter – all other components will be provided and installed by the Contractor.

11. Yard Hydrant: Provide a frost-proof yard hydrant (served by above water service) at location on site to be determined by the Owner. Yard hydrant shall meet the ASSE 1057 sanitary yard hydrant standard and shall drain into a reservoir located below the frost line. Hydrant shall not require winterizing to protect from freezing. Yard hydrant shall be supplied with an integral 1052 type double check backflow preventer, heavy cast iron head with lever and pail hook. Hydrant shall be lockable. The inlet of the hydrant shall be 1” FPT and the outlet shall be ¾” hose thread.

All moving parts are to be serviceable from the surface without the need to excavate the hydrant.

Yard hydrant shall operate at a maximum operating pressure of 125 psi.

3. Revise Section 09902 – Elevated Water Tank Painting as follows:

Delete Paragraph 2.3.5 in its entirety. (There is no logo or lettering proposed for the tank.)

Delete Paragraph 2.3.7 in its entirety. (Concrete is not required to be coated.)

Revise Paragraph 2.4.1 to read as follows:

1. General: Except for the underside of the tank bottom, which is specified below, the pedesphere dry interior coating system shall be the same as the wet interior tank coating system except that the finish coat thickness may be reduced to 6 – 8 dry mils.

4. Revise Section 13210 – Composite Elevated Water Storage Tank as follows:

Revise Paragraph 1.3.2.d) and 1.3.2.e) to read as follows:

d) Grade Slab Elevation: 586.00 ft (*see note below)

e) Final Grade Elevation: 585.75 ft (*see note below)

(Note to bidders: The above grade slab and final grade values were adjusted by 0.25’ to address question #33 below.)

Revise Paragraph 1.5.1.c) to read as follows:

c) Acceptable tank contractors qualified to perform the work specified herein are Landmark Structures, McDermott/CB&I Constructors, Inc., Caldwell Tanks, Inc., and Phoenix Fabricators & Erectors. Note that being named above does not in any way modify the tank contractor’s obligation to meet all requirements of the Contract Documents, including requirements from the Drawings and Technical Specifications.

Revise Paragraph 3.2.1.e) to read as follows:

e) The forming system for the pedestal wall shall be fully engineered and detailed with procedures to meet the increased demands of architectural concrete. The support wall shall be constructed with a jump form process using form segments prefabricated to match the wall curvature. Concrete pour height shall be a minimum of 4 ft. and a maximum of 12 ft. Form panels shall be designed for lateral pressures associated with full height plastic concrete head and eccentric loads resulting from the segmented wall pour procedure.

ADDENDUM #2 A2- 3

5. Revise Section 13211 – Spheroid Elevated Water Storage Tank as follows:

Revise Paragraph 1.3.2.d) and 1.3.2.e) to read as follows:

d) Grade Slab Elevation: 586.00 ft (*see note below)

e) Final Grade Elevation: 585.75 ft (*see note below)

(Note to bidders: The above grade slab and final grade values were adjusted by 0.25’ to address question #33 below.)

Revise Paragraph 1.5.1.c) to read as follows:

c) Acceptable tank contractors qualified to perform the work specified herein are Landmark Structures, McDermott/CB&I Constructors, Inc., Caldwell Tanks, Inc., and Phoenix Fabricators & Erectors. Note that being named above does not in any way modify the tank contractor’s obligation to meet all requirements of the Contract Documents, including requirements from the Drawings and Technical Specifications.

Changes to the Plan Sheets:

1. None.

Questions and Clarifications:

1. Q: Testing 01450, Item 1.5 requests "independent" inspector(s) for both welding and paint. As long as we provide qualified inspector(s) that are independent of the Superintendent's control, can these inspectors be employees of the tank company?

A: For the inspections and testing requirements listed in Section 01450 Paragraph 1.5, including foundation and concrete, tank welds, and tank coatings, the term independent means third-party.

These inspection and testing services shall be performed by qualified employees of an independent, third-party company. While these services will be paid for by the Contractor, the testing/inspection company(ies) shall not be owned or directly affiliated with the Contractor and/or Tank Manufacturer.

For other inspections required, such as code-required inspections or related items, such inspections may be performed by employees of the Contractor and/or Tank Manufacturer as long as this is allowable by code and the regulatory authority.

2. Q: Section 13211, Please delete the word "Foundation" from Item 1.5.3 in that not all tank firms construction the foundations with "direct employees" (but instead qualified local subcontractors).

A: The requirement for the manufacturer’s qualified supervisor to be onsite during these construction activities is, in part, intended to provide an additional assurance of quality control and accountability for the tank manufacturer. It does not prohibit the use of a qualified subcontractor to perform the foundation work, but does require that the tank manufacturer provide a competent supervisor for such work.

ADDENDUM #2 A2- 4

3. Q: Section 13211, With regard to the Mixing system, we would like to have alternative passive systems approved in lieu of the "Tideflex style" manifold system depicted. For example, the CBI Freshmix package. Note that active systems like the PAX or Gridbee mixers can even be more economical than what is spec'd.

A: Understanding that mixing system designs may vary by tank manufacturer, the “Y” shaped mixing system shown on D01, in conjunction with the specification, is included to establish a general standard. Variations from the depicted design will be considered and not unreasonably rejected if they meet the intent of effective mixing; however, any mixing system design is required to meet the computational fluid dynamics analysis requirement of the specification and the system shall be design to ensure that effective mixing occurs and that the inlet/outlet is configured and separated such that potential for short-circuiting is eliminated. The Town has a PAX mixer system in the existing Evening Star Tank; therefore, the Town will allow a suitably sized PAX mixer system as an alternative to the passive system. The Contractor would be responsible for obtaining certification from PAX as to recommended sizing and configuration, providing and installing the mixer, and providing the necessary electrical and controls for the mixing system.

4. Q: Does the Town have any restrictions on how much work, percentage wise, that the Prime

Bidder has to perform, as long as the firm meets the Qualification(s) stated? Said another way, Supplementary Conditions page 00800-8; item SC-7.07.A, states that the total amount of work subcontracted by Contractor shall not exceed 50% of Total Contract Price w/ out approval from the Owner.

A: Supplementary Conditions SC-7.07.A includes a “prior approval from the Owner” clause to allow for exceptions where warranted. Owner approval will not be unreasonably withheld. It is recommended that a potential bidder that anticipates not complying with SC-7.07.A should notify the Town (email via the Engineer is acceptable) prior to the bid date. Failure to obtain prior approval from the Town will not automatically be a cause for bid rejection, but the bidder assumes the risk of such rejection if the Town does not grant approval.

5. Q: Section 13210, Division 13, Part 3.2, Item 1.E. states the concrete pour height is to be 6’-12’.

Can you please revise this section to allow forming systems ranging from 4’-12’ so that we can be fully qualified to bid on the project?

A: The Contract Documents have been revised above to accommodate 4’-12’ form heights.

6. Q: Section 13211, For Item 2.3.14.b.1 and 2.3.15 for the mixing system, please provide the maximum and minimum inlet and outlet flow rates. Also provide the mixing times for the maximum and minimum inlet flow rates, and the allowable head loss at the maximum flow rate.

A: Details of the mixing system design will be coordinated with the Contractor during the submittal phase. Generally speaking, the Town’s main zone wells currently produce approximately 350-400 gpm of flow when running. This flow will typically be split between two tanks (the existing Evening Star Tank and the new Airmont Tank), though the split may not be even. The Town is currently designing a new treatment facility to accommodate newly constructed Well D, which is expected to increase production rates to 450-550 gpm.

ADDENDUM #2 A2- 5

7. Q: Section 09902, Item 2.3.5 provides details on the type of paint to use on the LOGO, but I’m not aware that we have details of what you want shown on the tank. Additionally, this sub-Item 7 goes on to have the concrete foundation coated….this is unusual and not of much benefit in my opinion. I’d either delete it, or at least clarify that only the exposed concrete be coated.

A: There is no logo to be included on the tank. Concrete coating is also not required. Paragraphs

2.3.5 and 2.3.7 have been deleted above.

8. Q: Section 09902, Item 2.4 requests that the Interior Dry area of the Waterspheroid (shaft and lower room) be coated “with the same system as the Interior Wet”. This is overkill in that the Interior Dry usually only gets two coats of epoxy, 6 mils max, vs the higher cost (and thicker) Interior Wet system (which is over 20 mils thick). Since this area is never exposed to UV damage or submerged in water, there is no need to (a) coat it so heavily nor (b) expect that it needs repainting during the life of the tank (re Lifecycle costs). Please show instead SP-10 blast w/ two coats of Tnemec 94H2O at 2.5-3.5 mils ea.

A: The specification was modified above to reduce the thickness of the finish coat to 6-8 dry mils in the dry interior area.

9. Q: Section 09902, Item 2.5 discusses painting of the tank’s interior Piping, but since the risers are stainless steel I assume this is an oversight / does not apply. And with the mechanical piping below the vertical riser(s) being Ductile Iron, do you want to spend the money coating that (especially since you’ll never see it under the insulation)? Similarly, there is mention of painting that Insulation – once again, something that probably should be deleted if we’re providing shiny aluminum jacketing already.

A: Stainless steel interior piping does not require coating. The ductile piping will require coating as specified. The insulation and associated aluminum or PVC jacket is not to be painted.

10. Q: This project has some significant landscaping/plantings which typically happens at the end of the project. Thus, can you confirm a couple things on this.

a. Is the warranty on the plantings 1 year? Typically, landscaping firms offer a 1-time replacement for plant survival.

b. Can you confirm who is responsible for tree watering? This can get expensive if we need to make routine watering trips to the jobsite, especially if we are demobilized and need to make return trips.

A: The one-year warranty period applies to the entire project, so plantings will be included.

Regarding the watering of plantings, once the Contractor has achieved final completion and has demobilized from the site, the Town will perform necessary watering of the plants for the remainder of the warranty period. Contractor shall work with the Town prior to final completion to agree to a watering schedule/plan for Town staff to follow. See this addendum for addition of a water service and yard hydrant to be located on the site to facilitate watering operations.

11. Q: Section 13210 & Section 13211, Paragraph 1.7.5.a calls for a Certified Health and Safety Technician (CHST) to perform spot inspections of the field activities and be a full-time employee of Tank Manufacturer. This requirement is not typical on elevated tank projects. Please confirm that CHST is not required.

ADDENDUM #2 A2- 6

A: The Contractor is responsible for safety of the jobsite and compliance with all applicable OSHA regulations. Unless otherwise required by OSHA, state/local code, or the Contractor’s or Tank Manufacturer’s safety program, the requirement for a CHST will not apply to this project.

12. Q: Section 13211, Paragraph 2.4.2.c require ladders to have 3/4“diameter rungs plug welded to the side rails. Our standard ladders use 3/4” square rungs with fillet welds all around to the side rails. Will our standard ladder, which, satisfies OSHA requirements and has been used for decades be acceptable?

A: Manufacturer-standard 3/4" square rungs with fillet welds will be acceptable, provided that as stated the strength/size is consistent with the general level of strength and functionality and that the ladder meets all OSHA requirements.

13. Q: Section 13211, Paragraph 2.4.11, Drawings C05, C06, D01: Specifications and Drawings require a Secondary Railing / Antenna Mount which consists of 42" high roof handrail with posts at 5.5' O.C., top rail, mid rail, kick plate, and (30) 2.5" x 8' tall antenna mount posts x 40' - 52' diameter. For the Water Spheroid option, the maximum diameter of Secondary Railing / Antenna Mount would be 34' any larger and the pitch of roof becomes too steep to be a "walkable" surface. Please confirm that a diameter of 34' for Secondary Railing will be allowed for the Water Spheroid option.

A: The specifications and drawings as shown are based on the base bid composite tank style. It is understood that the specific dimensions/arrangements shown may need to be modified to be compatible with the spheroid tank, as indicated within Paragraph 2.4.11. The details of this may be addressed during the shop drawing submittal phase. Reasonable accommodations to be most appropriate with the spheroid shape and dimensions are expected and encouraged, provided that the intent for functionality, safety, and appropriate use for antenna mounting is achieved.

Specifically, a reduced diameter for the secondary railing is expected with the spheroid tank style.

14. Q: Drawings C05, C06, D01: Drawing C06 calls for (30) 8' Antenna Mounts and Drawing D01 depicts the 8' Antenna Mounts attached to a secondary 42" high railing with post 5.5' O.C. The secondary (42" High) safety rail posts are not needed and only add cost and additional duration to schedule. Please remove the requirement for 42" High Posts on Antenna Corral and only incorporate 8' Tall Antenna Mount Posts with Top Rails (at 42" above roof), Mid Rail, and Kick Plate for Antenna Corral. Please confirm this is acceptable.

A: As long as the design of the antenna mounting posts and secondary safety rail meet the intent for functionality, intended use, structural strength, safety, etc. then it is acceptable to integrate the antenna mounting posts and safety rail as described. Note 4 on Drawing D01 specifically references “integration of the antenna mount posts into the secondary safety rail system” as an alternative that would be considered. Antenna post and safety rail design will be confirmed during the shop drawing submittal phase.

15. Q: Drawings G02, C05, C06, D01: Drawing details for Antenna Corral are contradictory:

• Drawing G02 lists the quantity of Antenna Mount Posts ranging from 27 - 36 vs Drawing

C06 which details a quantity of (30) Antenna Mount Posts.

• Drawing G02 lists the Dimensions of Antenna Corral as 40' - 52' diameter x 9' Tall vs

Drawings C05 and D01 which show Antenna Mount Post height = 8'.

• Please clarify which is correct.

ADDENDUM #2 A2- 7

A: Drawings C05, C06, and D01 provide the specific information required for the project. The brief notes referred to on Drawing G02 (labelled “Future Telecommunication Antenna Facilities”) were included for regulatory purposes, and while generally correct (for example, the required 30 posts is between 27 and 36) are less specific because they were developed for regulatory approval purposes.

16. Q: Section 13210 & 13211, Drawings C05, C06, D01: Specifications and Drawings do not list / detail material type or size, i.e. 1.5"ø Pipe, 2.5"ø Pipe, etc., for 42" High Railings (Inner and at Antenna Corral) Posts, Top Rail, and Mid Rail. CB&I standard Pipe Handrail is 1.5"ø pipe or tubing, please confirm that 1.5"ø Pipe or tubing is acceptable for 42" High Roof Railing Posts, Top Rail, and Mid Rail.

A: 1.5” rail diameter is acceptable for the safety rail components unless larger is required due to OSHA or other applicable safety requirements. (Antenna mount posts are called out as larger 2.5” diameter on D01.)

17. Q: Can you confirm the budget amount for this project?

A: The Town currently has approximately $5 million in funds budgeted for the construction project.

18. Q: the VDOT permit fees known? If unknown, can a cash allowance for permits be established so all bidders include the same value in their bid and the Owner only pays for actual costs?

A: VDOT land use permit fees are expected to be very low relative to the size of this project. A recent Town project with similar levels of work in the right-of-way (including a new gravel entrance drive and driveway culvert) included a permit fee of less than $200. As indicated in the contract documents, VDOT is also expected to require the contractor to obtain a surety/bond for the work in the right-of way. For purposes of the bid, bidders may assume that VDOT permit fees will be $500 or less and the surety/bond amount will be $25,000 or less. If actual costs are higher than noted above then the Owner will pay for or reimburse the difference.

19. Q: Section 01450, Item 1.4.2. Special Inspection cost can vary. Can a cash allowance be established to cover the costs of any Special Inspections so all bidders include the same value in their bid and the Owner only pays for actual costs?

A: It is anticipated that most, if not all, special inspections required may be performed by/through the required Structural Registered Design Professional in Responsible Charge and/or the required independent testing agencies (such as the foundation and concrete testing and tank welding test agencies) already required by the Contract Documents. If the Loudoun County building permit process results in additional special inspections beyond those reasonably inferred by the scope of work, specific requirements of the Contract Documents, and above statement, then the Owner will either direct-contract with the necessary special inspection agency(ies) or negotiate with the Contractor to add such additional inspection services. If the County requires specific special inspections that are required to not be provided by or contracted by the Contractor, then the Owner will direct-contract with the necessary special inspection agency(ies) for these inspections.

ADDENDUM #2 A2- 8

20. Q: It was mentioned at the pre bid meeting that the Owner will assist with coordinating clearing and widening of Yatton Road. The extent and costs of this work is unknown. Can a cash allowance for this work be established so all bidders include the same value in their bid and the Owner only pays for actual costs?

A: See commentary in the Pre-Bid minutes. Yatton Road is a VDOT road, however it is an infrequently travelled gravel road with a 30’ prescriptive right-of-way that is not routinely maintained. While currently capable of accommodating passenger vehicles, modifications will be necessary to accommodate large construction vehicles.

It is the Town’s intent that primary vehicular access to the site shall use Yatton Road direct from Airmont Road (719). The Contractor will be responsible for any necessary modifications to Yatton Road to properly accommodate construction vehicles, including entrance improvements from Airmont Road, tree/limb clearing, roadway modifications, etc. The Contractor shall maintain the access and upon project completion shall restore Yatton Road to pre-construction condition or better. Bidders may assume that permission for the Contractor to perform such improvements and road maintenance work within the 30’ prescriptive right-of-way will not be unreasonably withheld by the Town or VDOT. The Town will assist the Contractor with necessary VDOT coordination related to necessary road modifications and restoration.

21. Q: With site clearing not starting until November 15th can you confirm the Notice to Proceed date as November 15th?

A: If desired, the Notice to Proceed may be delayed until November 15 to coincide with the end of clearing restrictions.

22. Q: Drawing C02B – The existing wall structure is shown to be removed in areas where the proposed water line is to cross. Can a detail of the existing wall be provided to quantify the wall removal?

A: The existing “wall structure” is an old dry stacked stone wall (perhaps ~3’ tall) that over the years has sloughed/fallen such that in some cases is more like a partially overgrown rock berm.

While the stones vary in size, most can be picked up by hand. The portion of the stone wall/berm in the crossing area is expected to be easily removable using standard excavation equipment.

23. Q: Due to the nature of tank erection work and the travel distance for our field personnel, working weekends is advantageous for the project from both a cost and schedule perspective.

This is even true if the work allowed on the weekends is restricted to non‐ inspected work. Can you confirm that Saturday work will not be restricted??

A: Per the General Conditions (00700) and Supplementary Conditions (00800) Article 7.03, regular working hours are 8:00 a.m. to 6:00 p.m. Monday through Friday. Because the tank site is in close proximity to nearby residences, work during regular hours is preferred. Where appropriate, the Town will consider Contractor requests to perform work on Saturdays, Sundays, or beyond regular work times. Where the need or benefit exists, approval of such requests will not be unreasonably withheld.

Note that in cases where extended work days/hours are allowed, all work must adhere to Loudoun County noise ordinance requirements (654.02), which limit construction activities to 7:00am (9:00am on weekends) to 9:00pm in residential areas.

ADDENDUM #2 A2- 9

24. Q: Due to the nature of tank erection work and the travel distance for our field personnel, working weekends is advantageous for the project from both a cost and schedule perspective.

This is even true if the work allowed on the weekends is restricted to non‐ inspected work. Can you confirm that Sunday work will not be restricted?

A: See response to Question #6 above.

25. Q: Section 00800, Item 7.03 – can the work hours be adjusted to allow 7:00 am to 7:00 pm for normal construction activities?

A: See response to Question #6 above.

26. Q: Section 00800, Item 7.03. During the occasional times of extreme weather or unique construction activities can work be performed outside normal work hours?

A: See response to Question #6 above. Yes, generally speaking, unique tasks where extended hours are needed would be an example where extended work hours or weekend work would be allowed. Emergency or extreme weather situations will be handled on a case-by-case basis, but in those situations extended hours will not be unreasonably withheld.

27. Q: Section 13210‐1.3.5 references load combinations. The load combinations included are outdated and differ greatly from AWWA‐D107. Please confirm we are to use the load combinations published in the latest version of AWWA‐D107 for design of the composite water storage tank.

A: Load combinations from AWWA-D107, latest version, shall be used in lieu of those indicated in Paragraph 1.3.5.

28. Q: Drawing C05 – The expansion joint be shown to be located at the top of the pedestal. This is another tank manufactures standard detail, our design requires that the expansion joint be at the base of the pedestal, where it much more accessible. Can you confirm either location is acceptable?

A: A lower location for the expansion joints is acceptable.

29. Q: Drawing C05 – The Tank Section detail indicates “rest seats” are to be provided at a maximum spacing of 50’‐0”. Section 13210, Part 2.6.4. states that “rest platforms are to be provided at a maximum spacing of 50’‐0”. Can you confirm that both the Composite Elevated Tank and the Spheroid Elevate Tank are to provide rest seats, not platforms, at a maximum spacing of 50’‐0”?

A: The intent of the drawings and specifications is to establish a maximum 50’ interval between resting locations. This may be satisfied with OSHA compliant rest seats or platforms. In some cases, platforms may be preferred by the tank manufacturer as they may fulfill other purposes.

ADDENDUM #2 A2- 10

30. Q: Drawing C05 shows a 53’ min. tank diameter. While we will be close to this dimension we will surely vary. Tank diameter is determined by volume and head range. Please confirm this dimension as +/‐.

A: Correct. Minor dimensional adjustments to those shown are expected to suit tank manufacturer’s standard shapes, best accommodate project requirements, etc. These dimensional variances can be coordinated during the shop drawing submittal process.

31. Q: Drawing C06 shows the incoming waterline passing over the foundation. Our design will incorporate the incoming waterline into the foundation. Please confirm this is acceptable and we are not required to place the foundation deeper than required by our design to allow the waterline to pass over the foundation.

A: Foundation design is the responsibility of the tank manufacturer. As such, it is understood that details of the foundation design may vary from those shown. Penetrating piping should be suitably sleeved and otherwise protected to ensure that the foundation is not impacted and that tank loads are not transferred to the piping.

32. Q: Drawing C05 – The Tank Exterior Elevation identifies a 10’ wide x 10’ high overhead steel rolling door to be installed. A pedestal of this diameter does not warrant a vehicle door. We suggest a single 6’x7’ double door similar to the requirements of the Spheroid Tank option. Can you confirm the Composite Elevated Tank can match the requirements of the Spheroid Elevated Tank to provide a single 6’‐0” x 7’‐0” double door in leu of both a 10 x 10 overhead door and a 3 x 7 personnel door?

A: The composite style Base Bid is unchanged and includes the requirement for the 10’x10’ overhead door and separate personnel door. To address this question, an optional deductive bid amount has been included on the bid form for a 60”x80” double door in lieu of the overhead door and personnel door.

33. Q: Drawing C05 – The F.F. elevation is shown to be 586.0’. Section 13210, Part 1.3.2. states the Grade Slab Elevation to be 586.25’ and the Final Grade Elevation to be 586.0’. Can you confirm the Grade Slab Elevation to be 586.25’ and the Final Grade Elevation to be 586.0’?

A: Please assume finished floor (grade slab) elevation as 586.0’ to match the drawings. Resulting final grade elevation would therefore be approximately 575.75’. To be consistent, this addendum includes a revision to Section 13210 Paragraph 1.3.2 and Section 13211 Paragraph 1.3.2 to match those values.

34. Q: Drawing C06 – Note #5 indicates the interior horizontal mechanical piping to be ductile iron.

Section 13210, Part 2.6.15. states the piping through the base slab is to be ductile iron, but all other tank interior piping shall be stainless steel. Can you confirm the process piping at grade level can be either ductile iron or stainless steel?

A: Stainless steel piping will be considered acceptable as an alternative in lieu of the in-tank interior ductile iron mechanical piping. (Underground water piping and piping through the floor slab should be ductile iron.) Note that if stainless steel piping is used in lieu of ductile iron, flanges are still required to allow for future maintenance/replacement of valves and equipment.

ADDENDUM #2 A2- 11

35. Q: Drawing C02A – The location of the Primary Electrical Service is not shown on the site plan.

Can this location be provided in order to accurately price the secondary service to the tank?

A: The exact location of the electrical service has not yet been determined. It may be assumed that the service location will be on the project site, which is not large. The Contractor will be responsible for coordinating with Dominion Power to obtain and schedule power service and for necessary wiring and conduit from Dominion service location to the panel at the tank. Exact location of the service will be determined through coordination between Dominion Power, the Contractor, and the Town. Direct charges and fees from Dominion Power will be paid for by the Owner.

36. Q: Section 09902 Item 2.3. 5. Tank lettering and logos. Can you provide detailed information or a drawing of the logo(s).

A: There is no logo or lettering proposed. Section 09902, Paragraph 2.3.5 has been deleted above.

37. Q: Section 09902 – Who will be the Owners Independent Coatings Inspector?

A: While the Owner retains the right to obtain supplemental inspection services for the project, no specific selection of owner-provided inspectors has been made at this time. The owner may or may not provide its own coatings (or other specialty) inspection beyond that required to be provided by the Contractor. (See Section 01450.)

38. Q: Section 09902 ‐ Will containment be required for blasting operations? If so, what SSPC Guide 6 level will be required?

A: Contractor shall utilize appropriate industry practices and reasonable means and methods at their discretion to limit blast debris and paint droplets to within the project limits and to contain and dispose of residues in accordance with Federal, State and Local regulations.
