RFP 140R2020R0009

Amendment 0005

Friant-Kern Canal Middle Reach Capacity Correction Project Phase 1 Offeror’s Questions and Answers

Question 1: Sheet C-22 depicts the Lower Tule River Turnout in the upper left corner. There is a detail callout for Sheet C-504 detail. There is no sheet C-504. Is this supposed to be C-505?

Response 1: Yes. This callout should be C-505. See revision in Dwg C-22 that was issued previously with Amendment 0004.

Question 2: Re: Spec Section 31-23-19-3.4-B “Dewatering Existing Canal” a. Reference is made to Hydraulic Profile Drawings GC-6 & GC-7 for existing canal invert and low spots. GC-6 show typical trench section and GC-7 was not included in the plans. – Please review and send out plans showing the Hydraulic Profile of the existing canal and low spots.

Response 2: The reference should be to drawings G-6 and G-7 NOT GC-6 and GC-7. See revision to specification Section 31 23 19-5 issued previously with Amendment 0004.

Question 3: Please define what CLINs you are expecting to see in the proposal in reference to “e) Work schedules and crew sizes including total labor hours for the applicable CLINs” on page L- 14 and “f) Work schedules and crew sizes including total labor hours for the applicable CLINs” on page L-15.

Response 3: Page L-14 for Factor 1B, 1. d) and e) provide the requested information pertaining to the following CLINS: DUST ABATEMENT AND MAINTENANCE OF HAUL ROADS

(CLINS 7 AND 8) CONSTRUCT NEW CANAL INCLUDING EXCAVATION AND

COMPACTING EMBANKMENTS (CLIN 12 THROUGH 20) OVEREXCAVATION FOR

CANAL AND STRUCTURES (CLIN 21) TRIMMING EARTH FOUNDATION FOR CANAL

LINING FOR NEW PARALLEL CANAL (CLINS 22 AND 23) 3.5-INCH THICK CONCRETE

CANAL LINING FOR NEW PARALLEL CANAL (CLINS 24 AND 25) Page L-15 for Factor 1B, 2. e) and f) provide the requested information pertaining to the following CLINS:

CONSTRUCT NEW CANAL TIE-INS TO EXISTING CANAL (CLINS 32 THROUGH 33)

CONSTRUCT NEW DEER CREEK CHECK STRUCTURE, WASTEWAY TURNOUT AND

SIPHON (CLIN 34) CONSTRUCT NEW SIPHON STRUCTURES (CLINS 35 THROUGH 41)

CONSTRUCT NEW TURNOUT STRUCTURES (CLINS 42 THROUGH 50) CONSTRUCT

IRRIGATION AND DRAINAGE SIPHON EXTENSIONS (CLINS 52 THROUGH 53)

Question 4: A Stoplog Schedule has been provided on Drawing GM-3. The Schedule states that the opening size for Weir Stoplogs is 7-1/2” W x 10’ H, and that 18 sets of Weir Stoplogs are to be furnished. The single weir box structure in the Bid Drawings contains two (2 each) stop log openings that are 10’ wide x 13’ high. Please update the Stoplog Schedule on Drawing GM-3 to reflect the correct opening size and quantity of stoplogs to be furnished.

Response 4: The stoplogs for 7 feet 1/2 inch wide by 10 feet high clear opening called out on GM-3 are for check structure weir stoplogs (see S-12 and S-26); not for weir box stoplogs. Note that there is a typo in the clear opening width for these stoplogs in equipment schedule table GM-

3. The width of each opening is 7’-1/2” not 7 ½”. Correction will be made to the drawing GM-3.

The weir box slots as shown on drawing S-37 do not require stoplogs under this contract.

Question 5: Regarding the Environmental Past Performance requested in Factor 2A on page L- 16, in Amendment 003 Response 8, BOR referenced that we should provide environmental past performance information in a spreadsheet. However, the requirement seems to be looking for a narrative “The offeror shall describe approach to working with the Government to meet environmental requirements. The offeror shall provide a description of no more than 3 projects completed with the last 15 years that demonstrate similarity to this solicitation.” Please confirm that BOR is looking for a narrative along with the PPI spreadsheet as it relates to environmental past performance for Factor 2A.

Response 5: Please see the revised Section L included in this Amendment which clarifies that environmental past performance is a subpart of the requirement's Factor 2B - Past Performance Narrative. The page limitation for the narrative has been increased from no more than three (3) pages to reflect no more than four (4) pages.

Question 6: The RFP requires under Section L (p. L-10) that the Offeror’s Proposal provide in Volume 1 “Business Proposal Contents”. Section M provides the Factors for the Evaluation of Proposals. Section M does not appear to indicate that Volume 1 will be evaluated or scored. Will Volume 1 be part of the evaluation and decision on whom to award or will only those Factors listed in Section M, Factor 1: Technical Approach, Factor 2: Past Performance, and Factor 3:

Price, be part of the evaluation and decision?

Response 6: Volume 1 “Business Proposal Contents” will be evaluated under Factor 3: price in Section M.

Question 7: Under Amendment 0002 - Response 6 to Question 6 stated “The Government will use the subcontractor’s System for Award Management (SAM) certification to determine the socioeconomic status of each firm in accordance with FAR 52.219-8, “Utilization of Small business Concerns.” Under FAR 52.219-8, “Utilization of Small Business Concerns.”, Section (d)

(1) states “The contractor may accept a subcontractor’s written representations of its size and socioeconomic status as a small business, small disadvantaged business, veteran-owned small business, service-disabled veteran-owned small business, or a women-owned small business if the subcontractor represent that the size and socioeconomic status representations with its offer are current, accurate, and complete as of the date of the offer for the subcontract.” and Section (d) (3) states “The Contractor may not require the use of SAM for the purposes of representing size or socioeconomic status in connection with a subcontract.” (See attached excerpted from FAR 52) If the contractor may accept a subcontractor’s written representation of its size and socioeconomic status and may not require the use of SAM for the purposes of representing size or socioeconomic status in connection with a subcontract, will certifications from local jurisdictions such as CDOT DBE UCP and CA DGS SBE and/or will “self-certifications” be accepted?

Response 7: self-certifications will be accepted.

Question 8: If bidding as a Joint Venture, should both company’s Cage Code, DUNS, TIN (Tax Identification Number), Business Size, information be listed where required?

Response 8: Yes.

Question 9: In Amendment 3 ~ Response 6 to Question 6 states “Section L, Page L-15 Note iii – One page is defined as a single side of an 8 1/2" by 11” paper in this note. A single side of an 11” x 17” paper is twice the size of the “one page” definition and will therefore be counted as two pates as it relates to this requirement”. BUT, on page L-14 under “Factor 1A – Construction Schedule”, the Format paragraph requires the schedule to be printed formatted so that it can be printable on a 11x17 sized paper. Since a 11”x17” format is required for the construction schedule, will the 11”x17” construction schedule pages count as the same page equivalent as one side of double-sided piece of 8.5”x11” paper as listed in the first paragraph on page L-10?

Example: Factor 1A-Construction Proposal submitted contains 15 pages formatted as 8.5”x11” sized paper and 10 pages formatted as 11”x17” sized paper. Would that meet the 25-page maximum allowed for Factor 1A – Construction Schedule

Response 9: Yes. The combined maximum total number of pages shall not exceed 25 pages.

Question 10: The Past Performance Questionnaire states that the reference is to return the form to the Contract Specialist no later than June 17, 2021, 2:00 pm PST which was the previous bid date. Now that the bid date is revised, will the completed Past Performance Questionnaires be accepted until the new proposals due date?

Response 10: The completed Past Performance Questionnaires will be accepted until 2:00 pm PST on July 14, 2021.

Question 11: WBR 1452.215-82 (d).(c),(1) requires an Executive Summary to be included in the Technical Proposal. Is there a page size requirement for the Executive Summary (i.e. can it be printed on 11x17)?

Response 11: Executive Summary shall be no more than 3 pages and printable on 8.5”x11” sized paper.

Question 13: Drawing GC-9 shows the O&M road on the West side of the canal is 16’ wide for the seal coated aggregate base. On the siphon drawings (Drawings C-203 thru C-209) and tie-in drawings (C-302 and C-304) the road width is shown 18’ and 20’ wide, respectively. Please clarify if the Seal Coated O&M Road is 16’ wide, 18’ wide or 20’ wide.

Response 13: Seal coat required is 16.0' per Dwg GC-9. See revised Dwgs: C-203, C-204, C-205, C-206, C-207, C-208, C-209, C-302, and C-304.

Question 14: Please refer to Specification Sections 05 50 00 and 35 22 57. Specification Section 05 50 00, paragraph 2.1.B indicates that the stop log guides are to be epoxy-coated steel.

Specification section 35 22 57, paragraph 2.1.G states that the stop log guides are to be aluminum.

Please clarify whether the stop log guides are to be epoxy-coated steel or aluminum.

Response 14: The stop log guides and sill plates shall be epoxy-coated steel per Section 05 50 00, paragraph 2.1B. See attached revisions to Section 35 22 57.

Question 15: Specification Section 03 32 00, Paragraph 1.6.A states “The Contractor shall furnish a 5-year written warranty of the entire sealant installation against faulty and/or incompatible materials and workmanship, together with a statement that the Contractor agrees to repair or replace, to the satisfaction of the Government, any defective areas which become evident within the 5-year period.” Given the known and continued subsidence of the ground in this area, please consider removing this warranty requirement. The cracks and failure of the sealant due to continued subsidence is an unknown and unquantifiable risk that the Government is asking the Contractor to bear.

Response 15: See revise Section 03 32 00-7 Amendment 0005.

Question 16: Drawing C-407 – DEID-68 Turnout Plan and Profile show an open cut construction crossing of Road 192. Please confirm it would be acceptable to bore Road 192 with a casing pipe, install the carrier pipe with centralizers and then grout the annulus.

Response 16: The County of Tulare has approved the design documents with this crossing shown as an open-cut crossing.

Question 17: Drawing CD-3 lists three ground water wells to be abandoned by station number.

Drawing C-40 shows a fourth well to be abandoned, not indicated on CD-3. Please confirm this well is to be abandoned by the Contractor. If this well is to be abandoned, please provide details for abandonment (diameter, depth, etc.).

Response 17: The well identified on C-40 needs to be abandoned per revised drawing CD-3

Question 18: Request the proposal due date be extended an additional two (2) weeks from the.

current due date of July 2, 2021.

Response 18: Previously issued Amendment 0004 extended the date and time for receipt of offers to July 14, 2021 at 1:00 p.m. PST

Question 19: Referencing GC-8, please clarify what width of the O&M road that would need to be provided if the Keynote “E” material on the West Bank of the existing canal was to be used for borrow. Keynote “J” calls for a 12’ O&M road but also refers to drawing GC-15 which calls for a 16’ wide O&M road.

Response 19: The O&M road on the west side of the existing canal shall have 12' of gravel base and seal coat per keynote "J". Note drawing GC-15 was updated previously in Amendment 0003.

Question 20: Siphon Section B on Dwg S-8 (and Section B on Dwg S-15) reflect an interior construction joint (type) at the interface of the siphon walls and the deck soffit. Contractor respectfully requests this joint be deemed an “optional” construction joint. Please advise if this is acceptable.

Response 20: The construction joints at the interface between siphon walls and top slab are required as shown on the plans.

Question 21: Regarding well abandonments on sheet 32 / plan CD-3. The following table below lists three total well abandonment to happen. Although on sheet 53 / plan C-40 there is a call out

(D) that lists a well abandonment at approximately station 5786+00. Can you please clarify the number of well abandonments there are?

Response 21: The well identified on C-40 needs to be abandoned per revised drawing CD-3

Question 22: Would the agency please identify which stations ground water is anticipated in the excavation of the new channel?

Response 22: Contractors make their own assessment of the groundwater conditions based on but not limited to the data contained in the Geotechnical Data Report.

Question 23: Section 01 14 00 at page 79 identifies Utility Relocation Work By Others and identifies the Relocation Schedule with a Month Ending Date identified. If this work by other is not completed by the applicable Month Ending Date identified, please confirm that the Contractor would be entitled to a compensable time extension.

Response 23: The situation described is a potential change to the Contract. Additional details available at the time of occurrence would be required to determine if there would be impacts of time and/or money to the contract.

Question 24: If unidentified utilities are encountered that require removal and/or relocation, and the work is performed by others (e.g. utility owner or its contractor) and not the Contractor as extra WORK under 01 50 10, 1.6 F., is the Contractor entitled to a compensable time extension for any delays caused by removal/relocation by others?

Response 24: The situation described is a potential change to the Contract. Additional details available at the time of occurrence would be required to determine if there would be impacts of time and/or money to the contract.

Question 25: Detail 5 on Drawing GC-13 shows anodes installed 5’-0” away each side of the pipeline. SID S1 PIPE and SID S2 PIPE have less than 4’ of spacing between the parallel runs.

Should the anodes be installed on the outside of each pipe and not in between them?

Response 25: The anodes shall be installed on outside of each pipe rather than between the two pipes. Refer to revised drawing GC-13 included with Amendment #5

Question 26: Detail 5 on Drawings GC-13 only shows two anodes, however there are a total of 20 anodes on SID S1 PIPE and 16 anodes on SID S2 PIPE. Are the anodes to be placed 5’-0” from the side of the pipe along the pipe alignment? If so, what is the spacing between the anodes?

Response 26: Each pipe requires a single test station with 2 anodes each. Anodes shall be spaced at 15.0' apart and placed 5 .0' from the pipeline. Refer to revised drawing GC-13 included with Amendment #5.

Question 27: Per Amendment 0003 Question 8 Response, it was stated that “The Environmental past performance projects may be the same or different projects and shall be included on a separate spreadsheet” Please clarify that if we do choose to use different projects for the environmental past performance, does the required 3 page limit per project apply to the environmental past performance narrative? Do we use the same spreadsheet format provided for the 3 past performance projects?

Response 27: Please see the revised Section L included in this Amendment which clarifies that environmental past performance is a subpart of the requirement's Factor 2B - Past Performance Narrative. The page limitation for the narrative has been increased from no more than three (3) pages to reflect no more than four (4) pages, thus, no additional spreadsheet or entries will be accepted.

Question 28: Is there a page limit for the Key Personnel resumes?

Response 28: There is no page limit on key personnel resumes.

Question 29: Spec 43 25 06 2.2B; C-600 & C-601 For the storm drain submersible solids-handling pumps, a supplier (JCH) should be able to meet the minimum submergence level, but not operation in a dry pit. Does the minimum submergence level override the dry pit requirement?

Response 29: Yes, the minimum submergence level overrides the dry pit requirement.

Question 30: Please refer to contract drawing S-8, page 108 and drawing GS-2, page 97. These drawings depict the contraction and construction joints for the roadway box siphon construction.

The callout for the contraction joint refers to detail S-902 which details a waterstop to be located at this joint. The callout for the construction joint for the box culvert exterior walls refers to detail S- 118 which details a waterstop to be located at this joint. The callout for the construction joint for the box culvert interior walls does not refer to a detail. It is understandable that all exterior wall, slab and roof contraction and construction joints should have waterstop. Do the construction and contraction joints for the interior roadway box siphon walls, both horizontal and vertical, require waterstop in accordance with detail S-118? Please clarify.

Response 30: All construction and contraction joints for exterior structural walls require waterstops. Construction and contraction joints for interior structural walls do not require waterstops. This applies to both horizontal and vertical wall joints

Question 31: The pipeline for the turnout located at STA 5813+99 crosses Road 192 beyond the limits of the shoofly for Road 192. Can traffic be controlled to one-way traffic control while pipe is being installed? Can class 2 aggregate base be used for a roadway section until the permanent roadway HMA is placed?

Response 31: Yes, traffic can be controlled to one-way traffic with flaggers provided. Road closure of Road 192 is not permitted. Class 2 Aggregate base is not an acceptable temporary roadway material.

Question 32: Some proprietary software contains hard coded fonts and sizes in its formatted printouts (i.e. Primavera) that does not meet the proposal requirement of New Times Roman 10 point font. Will these printouts be acceptable for the proposal?

Response 32: Proposals are not required to use Times New Roman 10 point font. Section L, in more than one location requires, "Font sizes must be no smaller than Times New Roman size 10 type."

Question 33: The Schedule of Prices excel spreadsheet provided and is to be submitted is not in New Times Roman 10 point font. Is the formatting of this to be changed or will the provided formatting be acceptable?

Response 33: The Schedule of Prices spreadsheet will be accepted in the formatting with which it was provided in the solicitation.

Question 34: Specification 01 14 00, Section 1.10.C.1 was updated in Amendment 2 (added subsection 1.f) and was updated again in Amendment 4 (deleted subsection 1.d). In Amendment 4, subsection 1.f was not provided. Please clarify if the two Amendments should be combined or if the Amendment 4 changes overwrote Amendment 2.

Response 34: Subpart 1.f was inadvertently left out of Amendment 0004. See attached revised Section 01 14 00-12 that includes both changes.

Question 35: Specification Section 01 71 20, paragraph 3.6 was updated in Amendment 3 and again in Amendment 4. In Amendment 4, the previous changes appear to be overwritten. Please clarify if the two Amendments should be combined or if the Amendment 4 changes overwrote Amendment 3.

Response 35: Changes from Amendment 0003 were inadvertently left out of Amendment 0004.

See attached revised Section 01 71 20 with combined changes from Amendments 0003 and 0004.

Question 36: Can you provide a bidders list for project no. 20-C0907

Response 36: Bidders list is not available. Please see the site visit sign in sheet posted in amendment 0002.

Question 37: Earthwork section 31 30 00 Materials Testing. Do the type N1 and N2 materials need to be tested for sand equivalent value? And if yes what limits are allowed in the soil to be used as N1 and N2?

Response 37: No, Sand Equivalent testing is not required for N1 and N2 material types.

Question 38: Can you please provide existing and final profile design elevations for the shoofly at Rd 192?

Response 38: Refer to Drawings T-3, T-4, and T-5; on the profile view immediately above the stationing at 50-foot intervals are two sets of elevation data; the elevation on the left is the existing grade and the elevation on the right is proposed roadway grade.

Question 39: The CAD files provided do not provide any data for final elevations of the Canal and the Siphons/Crossing. Can you please provide the Auto-CAD data for the final finished design elevations?

Response 39: Design data is included in the drawings (Attachment 13 parts 1 thru 5) of the solicitation and the alignment files FKC_ALGN_PHASE-1.dwg and FKC_LOW_PHASE-1.dwg available as noted in Section C - Specifications/Appendices, Section 01 10 00 SUMMARY OF WORK Subpart 1.7 A.

Question 40: Are CAD files available for the proposed Canal? The alignment and the limits of work are provided but nothing as far as the new design. Is something that can be provided?

Response 40: Design data is included in the drawings (Attachment 13 parts 1 thru 5) of the solicitation and the alignment files FKC_ALGN_PHASE-1.dwg and FKC_LOW_PHASE-1.dwg available as noted in Section C - Specifications/Appendices, Section 01 10 00 SUMMARY OF WORK Subpart 1.7 A.

Question 41: Sheet 53 0f 203, Drawing: C-40, On Drawing C-40 note D requires the existing Groundwater Well at Sta ~5786+75 to be abandoned in place per Drawing CD-3. Please provide column A, B, C values on Drawing CD-3.

Response 41: The well identified on C-40 needs to be abandoned per revised drawing CD-3.

Question 42: Amendment No 2, Attachment 1 is a wage determination for Inyo, Kern, and Mono Counties. This project occurs in Tulare County. Please confirm we are to use the determination provided in Amendment No 2.

Response 42: Revised Wage Determination for Tulare County included in this amendment.

Question 43: Please refer to contract drawing T-7, page 198 of 203. Note 6 on this drawing states that isolated pavement repairs are to be approved by Tulare County and Government prior to start work and the isolated repairs are incidental to the work. Considering the work shown on the drawings for the HMA overlay covers approximately 5 miles of roadway, the volume of isolated repairs could be substantial. In addition, a scope of the approved repairs (i.e. full depth removal and replacement, etc.) is not defined, nor quantifiable. Could an allowance bid item be added to the project to cover the cost of these repairs?

Response 43: Refer to revised drawing T-7 that provides clarification on the isolated pavement repairs as requested. An allowance bit item will not be added.

Question 44: Specification section 05 50 10, part 1.6.H, states that any utility encountered along the line of work shall remain continuously in service during all operations under this contract. If an unknown utility is discovered in conflict with the features of the canal, such as an irrigation line, will the contractor be responsible to relocate unknown utilities in conflict with the work?

Response 44: The inquiry has cited the specification section incorrectly, and the inquiry will be addressed considering Section 01 50 10. Discovery of an unknown utility when potholing or during excavation work etc. will be addressed on a case by case basis. Relocation, abandonment, modification, or other suitable corrective action will be determined after the Contracting Officer or their representative has been notified.

Question 45: Specification section 01 29 00 part 1.13.B states “…constitute full compensation for canal excavation, hauling materials to required embankments, applying water to moisture condition materials placed in embankments if required, placing the material in the embankment, scarifying of refill at the top of the lining, refilling the additional excavation between the bottom of the excavation required and the line depth needed, excavating…”. The underlined part of that statement seems to be in conflict with part 1.14 “Overexcavation for canal and structures.” Please clarify where any “excavation required to be over excavated then refilled to the line needed” would not be paid under part 1.14?

Response 45: Overexcavation is to be paid for under part 1.14 (CLIN 21). The term refill used under part 1.13 (CLIN 12 through 20) is intended to refer to the top of lining refill work shown in Detail 1 on Draing GC-9. Specification Section 01 29 00 - 1.13.A and B shall have been revised to clarify this.

Question 46: Referencing Drawing GC-8, please confirm Keynote “C” on the East Bank of the existing canal is an optional borrow source for material and not a requirement to remove this material. There is a dark bold line tracing down the 1.5:1 bank for the new canal and flattening out at the Estimated Original Grade which implies this is the proposed final configuration grade for this area and therefore would require the Keynote “C” zone to be removed.

Response 46: Yes, the inside Bank Zone material (Keynote C) is an optional borrow source and also has specific constraints on when the material can be excavated. To respond to the second part of the question, refer to revised Drawing CG-8 that clarifies the overlapping areas in Keynotes I and C.

Question 47: Temporary bypass methods will be required for the following irrigation district pipelines: 54” TBID pipeline at Terra Bella Siphon 24” SID pipeline at Ave 88 18” SID pipeline at Ave 80 14” SID pipeline at Ave 80. This work will require temporary shutdown of the pipeline in order to install the bypass facilities and reinstall the new pipeline sections. Several questions need to be addressed in order to estimate this work: Can these pipelines be shutdown for a period of time? If the pipelines can be shutdown, for what duration can they be shutdown? Can the pipelines be shutdown multiple times (bypass tie-in, permanent tie-in, etc.)? What are the flow rates of each of the pipelines? Do each of the pipelines draw only from the existing FKC or from other sources?

Response 47: Pipelines will be out of service during the FKC outage periods defined under 01 14

00 - 1.10.C.4. Additionally, individual outages will require coordination and specific outage requests per Section 01 14 00 - 1.6. Duration and number of shutdowns will be entirely dependent on time of year, time of day, and water demand. Individual outage request dates, times, and durations shall be provided in Contractor outage request and pending COR approval per Section 01 14 00 - 1.6. Flowrates and Sources are as follows: TBID 54-INCH - Flow: 125 cfs, Source: FKC (via TBID Pump Station) Avenue 88 24-INCH - Flow: 7.1 cfs, Source: FKC (via SID-S3 Pump Station) Avenue 80 18-INCH - Flow: 4.0 cfs, Source: FKC (via SID-S3 Pump Station) Avenue 80 14-inch - Flow: 5.0 cfs, Source: FKC (via SID-S3 Pump Station).

Question 48: The contract documents do not contain permanent erosion control plans or specifications. Will this work be a separate contract?

Response 48: Specification Section 01 41 40 requires the Contractor to prepare and implement an Erosion and Sediment Control Plan for temporary measures during construction. Prepare offers based on this information.

Question 49: Specification Section 02 41 19, Paragraph 1.4.B - Reservoir Lining, it states that existing irrigation water reservoirs in conflict with the new canal construction will require demolition and disposal of the reservoir lining which is either concrete or PVC. Please specify what type of liner is located at each of the reservoirs that will be demolished during new construction?

Response 49: The basin located on the Merritt property shown on dwg C-22 is PVC lined with earth cover. The basin located on the Teapot Dome Water District property shown on C-22 and C- 23 is an earthen basin. The basin located on the City of Porterville property shown on drawing C- 23 is PVC lined with earth cover.

Question 50: Per Site Preparation section 31 10 00, Within the limits of clearing, the areas below the natural ground surface shall be grubbed to a depth up to 24 inches below the ground surface.

And In areas where stripping is required, the depth of stripping in agricultural land is anticipated to be less than one foot. What percent of root matter/organic material smaller than one inch in diameter or thickness will be allowed to be used in the embankment fill material not stripped in the grubbed section greater than one foot thick?

Response 50: See revised specification Section 31 30 00 2.1.B.1 for limits on organic compounds.

Question 51: Can the stripped material from the new Canal alignment be placed in the right-of-way adjacent to the new canal embankments?

Response 51: Yes, Atterberg testing is required for N1 and N2. Specific allowable limits are provided in ASTM D2487-17 as specified.

Question 52: Earthwork section 31 30 00 Materials Testing. Do the type N1 and N2 materials need an Atterberg test to determine Liquid Limits, Plastic Limits, and Plasticity Index of Soils? If ye what are the limits required for N1 and N2 materials?

Response 52: Yes, Atterberg testing is required for N1 and N2. Specific allowable limits are provided in ASTM D2487-17 as specified.

Question 53: Earthwork section 31 30 00 Materials Testing. Do the type N1 and N2 materials need to be tested for organic content? And if yes what are the limits allowed in the soil to be used as N1 and N2?

Response 53: Yes, materials shall be tested for organic content. Organic content shall be less than 3%.

Question 54: Drawing C-704, Section 5360+58.15 – This section, and many others through the C- 700 series of drawings show excavation outside of the LOW. Please confirm there is no excavation outside the LOW or does the LOW need to be adjusted at these locations?

Response 54: No excavation is allowed outside the LOW. Any lines shown outside of the LOW are drafting errors and have been corrected in the revised drawings provided as part of Amendment 5 ( C-704, C-707, C-708, C-709 and C-710).
