SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

RESPONSES TO QUESTIONS

WSLP-106 PRE-BID QUESTIONS

1. Section 31 62 16.00 indicates the 2 nonproduction piles used for PDA testing are shown on the plans.

What plan sheet shows these locations? Location not shown on drawings. PDA test piles shall be located within 200 ft of I-10 bridges unless the preload construction is underway. PDA test piles shall be located between the I-10 bridges or no more than 50 ft outside the I-10 bridges if preload construction is underway.

The PDA test piles may be used as part of the Contractor’s TRS. Settlement and vibration monitoring of the I-10 bridges must be established and approved prior to driving PDA test piles.

2. Are these two PDA test piles to be driven plumb? Yes, driving the test piles plumb is acceptable.

3. Note 9 on sheet S-404 states the TRS piles shall be cut off at the existing canal mudline.

Will we be allowed to pull the TRS sheeting that are south of the EBL bridge and north of the WBL bridge with a vibratory hammer? No. All TRS sheeting shall remain below the mudline.

4. Section 01100 paragraph 11 – Order of Work mentions Access Road J, but this road is not indicated on the plans. Is this a typo? If not, please indicate this access road on the plans. Yes this should say Access Road F. This will be clarified by Amendment. This is addressed by Amendment 0001.

5. Is there an access road to the WSLP-106 jobsite on the north side of I-10? Or is the intent for the entire project to be accessed from the south side of I-10? No. The access is as shown on the drawings.

6. Sheets S-302 and S304 reference Standard Mechanical Couplers, both vertical and horizontal.

How many of each are required and what are the sizes? Exact quantity will depend on Contractor’s rebar layout with respect to the 45 ft wide lowered wall section under the bridges. Vertical bars are #9s spaced at 6” on the flood side and 12” on the land side of the wall, however, vertical couplers may be spaced at 12” on both sides of the wall. Horizontal bars are #9s at 12” on flood side and land side of wall. Total of 228 #9 bar couplers estimated. Spacing of couplers shall not exceed 12 inches on center horizontally or vertically.

7. Are geotextile fabric and crushed stone in the temporary roads inside the TRS shown on plan sheet S404 measured for payment or is it incidental to the TRS? Temporary access road is to be designed by the Contractor. Temporary access road through the TRS is incidental to the TRS and shall be included under TRS item.

8. Please provide Government’s estimated quantities for Job items. Will provide. This is addressed by Amendment 0001.

9. The take-off quantity for Rip Rap seems to indicate the Rip Rap at the 72” culvert pipe crossing will be measured for payment under item 0037, but the Measurement and Payment paragraph in the spec states that the Rip Rap at the CMP Culverts is incidental to the Culvert item.

Please confirm the Rip Rap at the CMP Culverts will not be part of item 0037.

Riprap at CMP culverts is to be included under item 0035 and not be measured for payment. The 936 TON of Riprap listed for item 0037 is meant to include all riprap within the sheeted section of interior channel at I- 10 bridges.

10. Is Reserve Relief canal navigable for crane mounted barges and material deliveries from Lake Maurepas?

The Government cannot attest to whether the Reserve Relief is navigable.

11. Does the contractor have right of way to utilize the Reserve canal from Lake Maurepas? No. Provided access to the project is via Access Road F. The contractor, however, has the option to obtain right-of-way for his own convenience as specified in the project specifications.

12. Is the contractor allowed to perform excavation within the Reserve canal for floating plant access? No. The Contractor, however, has the option to obtain rights to perform excavation of the channel as specified in the project specifications.

13. Are the pile supported warning signs and navigation lights intended to be permanent? ((add to TRS Section) Warning signs are permanent. The navigation lights are to be temporary during construction to protect the TRS and boaters during construction. Specifications for the lights shall meet industry standards and be submitted for review and approval as part of the TRS submittal. The sign should be typical regulatory marker used to aid navigation. Signs shall be located on each side of the floodwall in the middle of the channel. Sign panels shall 2’x4’ and be fabricated in one piece from 0.125inch thick, 5052-H38 or 6061-T6 Aluminum Alloy conforming to the requirements of ASTM B 209. Warning signs shall be reflectorized with florescent orange retro reflective sheeting. Illustration below.

14. Are there specifications for these warning signs and navigation lights? See response above.

15. The approximate location of these warning signs as shown on plan sheet S-403 would block access for floating plant. Could these signs be offset to the side to allow safe passage of marine plant? Location may be adjusted as necessary for floating plant access but shall remain as close as practical to middle of canal.

Warning sign shall be further away from TRS in east-west direction than floating plant but within the project right of way.

16. Specification 01100, paragraph 30 states “Note that there is an active existing 4” ethylene Shell gas line to be relocated by the Owner before the interior drainage channel work may be performed”.

When is this relocation work scheduled to begin and when is this relocation work scheduled to be completed? The interior drainage channel is one of the very first orders of work and must follow embankment operations and be completed prior to TRS construction. Any delay in Shell’s relocation is critical to an already tight schedule of 1,095 calendar days.

The relocation will be complete no later than April 1, 2024 as per Note 5 on the bid schedule. Note the work option will not be exercised until the Shell relocation work is complete.

17. Specification 01100, paragraph 33 states “No H-piling for the T-walls shall be driven until the preload is complete and the preload has been removed. No H-piling shall be ordered until after the PDA testing is complete and final pile lengths have been provided by the Administrative Contracting Officer”.

Can the PDA testing be performed prior to the preload being complete and removed? Can no h-pile for the T-wall be driven until both preloads have been removed? The intent is for no piles to be driven immediately adjacent to the preload so that the test does not include improvements to soil via the preload. PDA test piles shall be located within 200 ft of I-10 bridges unless the preload construction is underway. PDA test piles shall be located between the I-10 bridges or no more than 50 ft outside the I-10 bridges if preload construction is underway. The PDA test piles may be used as part of the Contractor’s TRS. Settlement and vibration monitoring of the I-10 bridges must be established and approved prior to driving PDA test piles.

Monoliths BR1, T5, T6, T7 and BR2 may have H-piles installed during the preloading. Installation of piles for T1-4 will have to wait until after the preloading is complete south of I-10. Installation of piles for T8-11 will have to wait until after the preloading is complete north of I-10.

18. Please consider extending the period for questions. This is addressed by Amendment 0001.

19. Specification section 01 53 00.02 12, paragraph 1.2.2 states that flood event price and payment includes all work required to repair and restore all damage to temporary construction and that repairing damage to permanent construction is in accordance with the changes clause. Paragraph 1.4 states that the contractor is responsible to repair and restore damage to temporary and/or permanent items. Please clarify if the contractor is responsible for the cost of repairing and restoring damage to permanent items caused by a flood event or if damage to permanent items will be handled under the changes clause. Damage to permanent items will be handled by the changes clause.

20. Specification section 01 53 00.02 12, paragraph 3.1.3 mentions vibratory hammers. Note 4 on drawing S- 404 states that the use of vibratory hammers is not allowed for the installation of any piling. Please clarify.

No vibratory hammers are allowed. Reference to vibratory hammers in 3.1.3 to be deleted.

21. Specification section 31 41 16.00 12, paragraph 3.1.1.3 states that the use of a vibratory hammer is not allowed for driving sheet piles under and on each side of the I-10 bridges for monoliths BR-1 and BR-2 and for each wall of the interior canal.

Can vibratory hammers be used to install permanent sheet piles for all other monoliths outside of BR-1 and BR-2? No.

Can vibratory hammers be used to install the angled legs of the interior drainage channel sheet pile walls that are outside of the bridge limits? No

Can vibratory hammers be used to install temporary sheet piles outside of BR-1 and BR-2? No

22. Is there a certain distance equipment and pile driving leads must stay away from the I-10 bridges? No pile driving equipment shall come into contact with the existing bridges. No pile driving equipment shall encroach between the outside of the concrete barrier rails in the space above the bridge decks. Piles must have at least 3 diameter spacing from the existing 54” oval bridge piles. The Contractor shall orient pile driving equipment so as to not jeopardize public safety on the roadway.

23. Will any type of traffic control and/or traffic control devices need to be implemented on the I-10 bridges when installing full length piling next to the bridges? No.

24. Specification section 03 31 00.00 12, paragraph 3.1.4.6 states that concrete pumps may be used when approved.

Will concrete pumps be allowed? No objection if all the requirements listed for pumping are met.

25. The cross sections on drawings C-301 thru C-306 depict the sand base and levee embankment being placed below the existing ground line. Is the Government’s intent to excavate to these template lines and grades prior to placing the sand base and levee embankment? No. Cross Sections shall be revised by Amendment. This is addressed by Amendment 0001.

If this area is to be excavated, can the material be spread onsite? This area is not to be excavated and will be clarified by Amendment. This is addressed by Amendment 0001.

Will this material be measured for payment from the template line shown on Drawings C-301 thru C-306?

This area is not to be excavated and will be clarified by Amendment. This is addressed by Amendment 0001.

26. Is the embankment material placed in the preload sections measured and paid under the “Embankment, Compacted Fill” item? Yes.

27. Drawing C-206, note 10 states that 4.75 feet of settlement is anticipated by the end of construction. How much settlement is anticipated during the initial 6 month preload hold period? 4.75 ft of settlement is anticipated for center of levee at end of construction. Note 10 is incorrect for the preload. Settlement at center of preload after initial 6 months is expected to be 1.5 ft to 2.5 ft. Total settlement at end of construction is expected to be 5 ft to 7 ft at the center of the preload. A revised C-206 will be issued by Amendment.

28. How is the additional embankment material that will be required due to settlement of the preloads during the stage 1 hold period measured for payment? All settlement of embankment is to be measured by survey via the use of settlement plates with riser pipes.

29. Please confirm that settlement gages will be used to measure settlement during the Stage 2 6 month hold period and the Stage 3 8 month hold period. Yes.

30. Section 00010 Bidding Schedule, Items 0022, Item 0023, Item 0024, and Item 0025 are all shown with LF as the unit. Please clarify. This is a typo. Items 0022 thru 0025 for sheet piling are to be measured by SF. This is addressed by Amendment 0001.

31. What is the length of the CSX gas line to be removed? The pipe shall be removed within the limits of the Option Work Area. This measures to be approximately 107 LF of pipe.

Is it removed from the R.O.W to R.O.W limits? No. Removal outside of the WSLP 106 Option Work area will be done under another Contract as necessary.

32. Does the I-10 Canal Spoils that are noted to be removed, need to be hauled offsite?

Or can the spoils be spread between the toe of the new levee and the new Drainage Channel?

I-10 canal spoil need not be removed from site. Placement of this spoil between the interior channel and toe of levee is acceptable similar to channel excavated material. Placement of this material is not allowed near I- 10 bridges (see note at bottom of C-202).

33. Specification section 31 11 00.00 12 is unclear whether the stumps between the levee toe and the drainage channel are required to be removed. Can the stumps in this area remain in place, or do they need to be removed? Please clarify. See section on C-200 which assists in showing clearing and grubbing limits.

Stump removal is listed under grubbing. Grubbing is not required between the interior channel and 15 ft beyond toe of levee.

34. Specification section 01100, paragraph 3(h) requires a temporary safety fence around the I-10 bridge area as shown on the drawings. No information is shown on the drawings. Please clarify. No temporary safety fence will be required. This paragraph will be deleted by amendment. This is addressed by Amendment

35. Specification section 00100 Instructions to Bidders, paragraph bid opening. Please confirm that the date and time for the bid opening is June 20, 2023 at 10:30 AM.

All bids received after 10:30 AM CST on Thursday, June 29, 2023, will be considered late.

36. Drawing C-211 “Typical Full Levee Section” detail shows the wick drain tip elevation at -30.0. “Horizontal Strip Drain and Wick Drain Overlap Details (Plan View)” notes Vertical Wick Drain Installed to Tip at EL -

50.0. El. -30.0 is correct for WSLP 106. Drawing to be revised by Amendment. This is addressed by Amendment 0001.

37. There appears to be a typo regarding the bid opening date listed on page 12 of the specifications. It is listed as May 20, but should be listed as June 20, 2023 per the latest solicitation. The Bid Opening is amended to Thursday, June 29, 2023, at 11:30 am CST. The Contracting Officer and Contract Specialist will begin downloading bids at 10:30 AM CST, which is the bid submission receipt cutoff time. All bids received after 10:30 AM CST on Thursday, June 29, 2023, will be considered late.

38. Is there an approximate acreage for clearing and grubbing? Approximate area of clearing under base work is 44 acres. Approximate area of grubbing under base work is 27 acres.

39. Has the shell pipeline been relocated? If not, will it be relocated before a notice to proceed is issued?

No. The work option will not be exercised until relocation by the utility owner is complete or no later than April 1, 2024 as per Note 5 on the bid schedule.

40. What is the depth, length and size of the CSX pipeline to be removed? The CSX line is 6” diameter. Line is to be removed within the limits of the Option Work estimated at 107 LF. Depth of burial is approximately 5 ft.

41. Is there contact information for the former owner of the CSX pipeline if more information is desired before removal? The line is abandoned. Contacting the owner of the abandoned line is not required. See spec section 01100 paragraph 10 (c) which lists contact phone number for the Louisiana Gas Development Corporation.

42. Is the steel catwalk to be paid for by the miscellaneous metalwork bid item, or should it be included with the reinforced concrete floodwall bid item? See spec section 05 50 04.02 12 for miscellaneous metalwork paragraph 1.2 which lists the catwalk as part of the work.

43. Please provide a breakdown of lump sum items. See question 50. This is addressed by Amendment 0001.

44. Can you please provide estimated quantities on items of work for which bids are being solicited on a job/lump sum basis? See question 50. This is addressed by Amendment 0001.

45. Can you please provide an approximate depth of the gas lines marked “do not disturb” as referenced on sheet V-101, and will the location of these line be field marked/identified by the respective companies before a notice to proceed is issued? The access road across these lines is outside of the project right of way and will be constructed prior to NTP.

46. “Please confirm the total width of the reinforcement fabric in regards to both "Typical Levee Section at Turnaround" on Sheet C-201, "Typical Levee Section at Grouted Riprap" on Sheet C-202, and "Typical Sections" Monoliths T1 and T11 and Monoliths T2 and T10 on Sheet C-202.” Refer to C-206 for the Geotextile within the surcharge. The rest of the levee is a constant width.

47. CLIN 0022 through 0025- should this measurement be SF in lieu of LF? This is addressed by Amendment

48. Sheet C-207 Phase 2. Note 2- Do not close off the middle of the existing I-10 canal until approved by the contracting officer. In planning our sequence & mean/methods, please elaborate/provide more detail on this requirement and when approval will or will not be granted (ie. what is closing this contingent on or what would not allow it to be closed) (as the project permanently closes this path). The closing of the canal is contingent on the establishment of the interior drainage channel on the land side of the levee alignment connecting the I-10 canal back to the Reserve Relief Canal to maintain drainage patterns. See Phase 2, note e. The interior channel will route water around the WSLP 106 floodwall crossing to a pump station (by others) at Reserve Relief Canal. The connection of interior channel to Reserve Relief Canal is the Option Work on this project and cannot be completed until the existing gas line is relocated by Shell. Relocation of the Shell line is to be completed by no later than April 2024.

49. Sheet C-009 there are notes between TRS and new drainage canal stating Existing I-10 canal spoil to be removed to El 0.0 between R/W to R/W. How is this work measured and paid? What are the north and south station limits of this requirement? There will be no direct measurement for this work. Payment shall be included under “Drainage Channel Excavation” which is paid by JOB. Approximate north-south limits of existing canal spoil above El. 0.0 are shown in profile on Sheets C-103, C-106 and C-108.

“52.236-4 PHYSICAL DATA (APR 1984)

Data and information furnished or referred to below is for the Contractor's information. The Government shall not be responsible for any interpretation of or conclusion drawn from the data or information by the Contractor.

(a) The indications of physical conditions on the drawings and in the specifications are the result of site investigations by surveys and borings. Field notes, graphic boring logs, field and laboratory test results, and other data on which this information is based are available at U.S. Army Engineer District, New Orleans, Corps of Engineers, Attn:

CEMVN-ED, 7400 Leake Avenue, New Orleans, LA 70118-3651, and access thereto may be had upon request.

(b) Weather Conditions. Data on weather conditions may be obtained from the National Weather Service.

(c) Transportation Facilities. The construction access will be via Airline Highway to Access Road F. No left hand turns, or U-turns are allowed on Airline Hwy except at signalized intersections or where a queuing bay exists to avoid blocking travel lanes.

Access Road F is a shared access road. The Government contractors will be utilizing the access road to complete their portion of the required work. Currently, there is a pile load test being conducted at the end of Access Road F. Construction of the new access road, interior drainage channel, and culvert crossing at the end of Access Road F will not be available to the Contractor until October 1, 2023. Prior to this date, the Contractor may access the site provided their operations stay at least 200-feet clear of the pile load test area. On the access roads, the Contractor shall maintain dust control, grade the road, fill holes, and low areas. Access for tree clearing and canal excavation is typically performed utilizing amphibious marsh excavators and airboats to transport personnel.

The Contractor shall transport Government personnel by airboat to inspect the work in progress. Airboat(s) shall also be on standby to transport workers for medical treatment in case of injury or illness.

(d) The Contractor shall keep streets free of mud, tracking, spillage and/or other surface pollution from his/her equipment and operations. The Contractor shall take whatever means required (i.e., street cleaners, manual labor, water trucks with sprayers) as often as needed to maintain clean streets near the work site. All debris resulting from street cleaning operations shall be hauled off-site and disposed of properly. All vehicles shall utilize the truck wash down racks so that vehicles have clean tires before entering onto Hwy 61.

All sheet piles shall be driven to the depths shown on the Contractor' shop drawings. The workspace under the bridges with low headroom will require driving of the sheet piling or any other elements of the Contractor's TRS design in the sections of short lengths and weld splicing them as driving progresses to the tip elevation. Pilings shall be driven by methods that insure proper interlocking throughout their lengths and prevent damage. Pilings damaged during driving or driven out of interlock shall be removed and replaced. A vibratory hammer for pile driving is not allowed. All piles shall be driven without the aid of a water jet, unless otherwise authorized. Unless specifically indicated otherwise, each run of piling wall shall be driven to grade progressively from the start and pilings in each run shall be driven alternately in increments of depth to the required depth or elevation. On each day of sheet pile driving, the Contractor shall stab only the number of piles that can be driven to grade by the end of the day, and all piling stabbed shall be driven to grade by the end of each working day except that the last two piles may remain tapered up to receive the next days piles. If the piling next to the one being driven tends to follow below final grade, it may be pinned to the next adjacent piling. The Contractor is advised that buried stumps or similar debris may be encountered periodically on the sheet pile wall alinement and appropriate consideration should be given to hard driving conditions should they occur. Piles shall not be driven within 100-feet of concrete less than 7 days old nor within 30- feet of concrete less than 28 days old.”
