59. Question: Does the counterweight need to be per the detail in the plans or can the contractor implement their own design as long as it meets the weight and stability requirements?

Answer: The Contractor may submit a different design for the counterweight. See revised Technical Specification 02 41 00.02, Paragraph 1.5.1.

60. Question: Does the existing condition grading file accurately depict the current conditions at the Phase I monolith construction?

Answer: The topographical surface provided near the upstream monoliths represents the most recent survey data and is believed to be reasonably accurate relative to the current field conditions. Site topography is subject to change due to ongoing operations of the current contractor.

61. Question: Since Phase 1 and 2 overburden excavations will be a done at a different time than phase 3 overburden excavation there will be a need to lay back the material. See attached drawing for a visual representation:

a. Will be the required slope be 1.5:1?

b. Since it will be approximately a 93 ft slope will it be required to have any benches? If so how many?

c. Will the toe of the slope be starting at station 8+00 or is the top of the slope at 8+00? If the top of the slope is at 8+00 it will significantly hinder the amount of work done in Phase 1 and 2 overburden excavations as well as the corresponding rock excavation. We would prefer the toe to start at station 8+00 and lay back into phase 3

d. If allowed to have the toe start at station 8+00 and the lay back slope into the Phase 3 overburden excavation will we need to take any preventive measures in regards to the tailwaters?

Answer: Refer to specification section 31 00 00 and drawing 61N651-19.

Our firm has constructed approximately 60 main chamber bulkhead slots on the Upper Mississippi River and I know for a fact that this work can’t be safely completed in such an abbreviated period. Please reconsider the performance period for this feature of work. I would recommend extending that period to at least 60 calendar days.

Answer: Reference the Government’s response to Question #35.

65. Question: Please clarify the types and level of insurance coverages required under the contract.

Answer: See revised section 00 73 00 SCHEDULE OF INSURANCE.

66. Question: What are the load restrictions with respect to length, wheel load, total load, length, and height that can be transported on the highway over Kentucky Dam as well as the height between the lock and Kentucky Dam?

Answer: Reference the Government’s response to Question #57 for bridge load restrictions.

67. Question: What are the load restrictions with respect to length, wheel load, total load, length, and height that can be transported on the highway over between the lock and the disposal site by the US 62/641 bridge over the abandoned P & L Railway?

Answer: Reference the Government’s response to Question #57 for bridge load restrictions.

68. Question: Reference Section 02 41 00.02 “Bridge Demolition”; Paragraph 3.4.1 “Regulation of Removed Materials” states: “ … The maximum particle size of material to be placed in government designated disposal areas shall be three feet (36 inches) in the longest dimension.” The bridge deck may be removed in pieces that have dimensions exceeding 36”. Can these pieces be disposed of in the government designated disposal areas if they are buried or covered with soil?

Answer: Bid as specified. However, the Contractor may submit a request for information to vary the size of debris allowed by the Technical Specifications post award. The Government considers all Contractor requests for information and makes determinations based on contract requirements and benefit to the Government.

Answer: Yes. See "Construction and Demolition Sequence" notes on Drawing 80N760-3.

70. Question: Drawing 80N760-8, Note 1 states: “REMOVE SLAB CURB & SIDEWALK WITHIN STAGE LIMITS. ….” and includes the wording “LIMITS OF REMOVAL 85’-0” DEMOLTION STAGE 1” . Drawings 80N760-9 and 80N760-10 show additional “Stages” of demolition. Does this mean the concrete deck, including curbs and sidewalks, cannot be removed completely from the West Abutment to the East Abutment before removing the structural steel members?

Answer: See Note "Demolition Methods" on technical drawing 80N760-1A for notes on alternative demolition sequence.

71. Question: Drawing 80N760-13 provides a basic cross section through the railroad bridge.

However, there are no details that show structural member anchorages that connect concrete ballast to structural members, reinforcing steel layout, or structural members that may cast into the concrete ballast. Can the contractor assume the concrete ballast does include any of these features? If they are present, what are their dimensions and their frequency? Are any drawings available that can provide more detail regarding how the concrete ballast is or isn’t connected to the structural steel members?

Answer: As-Built drawings of the former railroad bridge and former powerhouse access bridge have been added to the reference drawings.

72. Question: Are any drawings available that provide structural details of the P & L Railway Bridge?

Answer: Reference the Government’s response to Question #71.

73. Question: Was some sort of stay in place form left between the 4-1/4” I-beams that are mentioned throughout the drawings for demolition of the US 61 Highway bridge and the former access road bridge?

Answer: Yes. See Reference Drawing 80H436 R1 for more details.

74. Question: Drawing number 61N241-18 shows a total of QTY. 7 anchors to be installed in EL-16. Drawing number 61N241-24 indicates QTY. 5 anchors to be installed in EL-16.

The drawings are listed on Stantec Drawing 80N760-1A. We contacted several government agencies and were not successful in obtaining any of the drawings. Please provide the referenced drawings for the four existing bridges that get demolished in SOLICITATION NO.

W912P518B0005.

76. Question: Has a hazardous material survey been performed for the existing maintenance building scheduled for demolition? If so, please provide. If not, will the contractor have to provide prior to demolition?

Answer: See Paragraph 1.2.1 of Section 02 41 00 in Appendix A of the Specifications.

No asbestos or lead paint are anticipated to be in this existing structure.

77. Question: There is an existing riprap swale within the US lock excavation on the NE side.

Does this swale generate/affect any dewatering scope? Can a volume be provided?

Answer: This riprap is for slope stabilization not related to drainage and does not contribute to the dewatering volume any more so than the rest of the excavation.

78. Question: Are there any elevation limits to any of the disposal areas?

Answer: No, but the requirements of note 7 on drawing 61N247-74 must be met.

79. Question: CLIN 3201-00 of the Base Bid Schedule refers to a “Temporary Maintenance Building”. Please clarify if this is intended to be the CLIN for the New Maintenance Building, what is the significance of the word “Temporary”

Answer: See the revised Bid Schedule and section 01 22 00 for revised CLIN 3201-00 name of "Maintenance Building".

80. Question: Drawing 61N241-18 appears to have redundant anchor numbering in Monolith EL16. There is a vertical anchor on the lock side numbered AN16-3 and a vertical anchor on the land side also numbered AN16-3. In cross-referencing Drawing 61N241-24, it appears that the land side vertical anchor labeled AN16-3 is not required. Furthermore, Drawing 61N241-18 shows 4 anchors on the land side and the details on Drawing 61N241-24 only show two anchors on the land side. Please clarify.

81. Question: Drawing 61N241-18 appears to have anchors in Monolith 18A mislabeled as AN17-8 and AN17-9. Please clarify.

82. Question: Specification 01 00 00 Page 16 Paragraph 1.21.2.1 Option 1 states there are vertical anchors in Monoliths EL-22 thru EL-25. We only find four vertical anchors in Monolith EL-25. No vertical anchors are called for in Monoliths EL-22 thru EL-24. Please clarify.

Answer: See revised Paragraph 1.21.2.1 of Section 01 00 00 for clarification.

83. Question: Specification 01 00 00 Page 17 Paragraph 1.21.2.3 Option 3 states there are inclined anchors in Monoliths EL-24 and EL-25. There is no reference to the inclined anchors in Monoliths EL-22 and EL-23. Please clarify.

Answer: See revised Paragraph 1.21.2.3 of Section 01 00 00 for clarification.

84. Question: Can work be done on the demolition of the existing structures over the existing lock during non-outage periods (with barge traffic below the work area) if adequate debris capture is provided?

Answer: Yes, if it can be demonstrated to be safe after review and approval of the contractor's demolition plan by the Contracting Officer and the U.S. Coast Guard.

85. Question: May USACE provide an inventory of the permanent materials they will be providing? i.e. Stop logs

Answer: Yes. See revised Technical Drawing 68N200-10.

86. Question: The work in Option 5, the bulkhead slots for the stoplogs, seems to run parallel to the demo of the bridges above. We believe this will be a safety concern and are asking for an extension on the 24 day shutdown of the existing lock.

87. Question: Also after speaking with others that have prior experience retrofitting bulkhead slots, we believe it will be another driver for needing an extension. We kindly request to allocate 60 days for the lock shutdown.

88. Question: Specification Section 32 23 06 There are potentially conflicting wording in the blasting specs regarding the use of blast mats – can the requirement for the use of blasting mats be clarified?

a.3.2.6 “The Contracting Officer's Representative may require blasting mats for shots downstream of 8+00.”

b. 3.2.11 “Protective blasting mats shall be kept onsite and used on shots when flyrock is a concern.

c.3.3.1 “The Contractor shall cover all production shots with blasting mats.”

d.3.7.5 “Blast mats are required for all blasts upstream of station 8+00 to prevent flyrock.”

Answer: Blasting mats are required upstream of station 8+00 to protect the operating lock and new upstream monoliths from potential flyrock. Blasting mats are not required downstream of station 8+00, unless, in the opinion of the COR, they are necessary to prevent flyrock. The referenced paragraphs have been amended to clarify when the use of blasting mats is required, see section 31 23 06.

89. Question: Please provide clarification on any temporary matting that will need to be put down during the process of excavation, i.e.. Between Option 6 and 9.

Answer: Erosion control matting is required on permanent soil slopes, as described in the notes of the excavation section drawings 61N651-21 to 61N651-27. Matting is not required for temporary slopes except where required under specification 01 57 19 Temporary Environmental Controls.

90. Question: Specfication Section 31 60 00 paragraph 3.1.1 Is there any need for shotcrete on the job? It is show in specifications but not included in the bid item list. If it is required please refer to where.

Answer: After award, the contractor will be required to submit, for approval, a slope protection plan that may include shotcrete, or other method proposed by the contractor on an as needed basis, as described in specification 31 23 05 Lock Excavation, paragraph

3.6. Section 31 60 00 has been amended to remove the reference to shotcrete.

91. Question: In Disposal Area D are there any height restrictions for grading or any restrictions for how far away from the water it needs to be?

Answer: See Technical Drawings 61N247-74 and 61N247-75.

92. Question: May you provide the design requirements for the debris shield to be installed underneath the demolition of the bridges? Loadings?

Answer: No. See revised Technical Drawing 80N760-1A.

93. Question: Diaphragms and stringers of the existing bridges to be removed extent to the same elevation (Low chord) obstructing the access under the bridge. A demo shield placed

1 foot below the low chord will not provide access to work under the bridge. The bottom of the debris shield should be located at least 4.5 feet underneath the carrier beams so that someone is able to move from section to section under the bridge?

Answer: See Demolition General Notes on revised Technical Drawing 80N760-1A.

94. Question: How the erection of the containment system or any access under the bridge is expected? Will this need to happen during the lock shutdown period?

Answer: Reference the Government’s response to Question #93.

95. Question: May you provide the railroad as-built plans.

96. Question: How the personnel performing Lead abatement will access underneath the bridge if the containment system is only 1 foot below the girders?

97. Question: If a containment system is not necessary. Any other access method, i.e.

manlifts, will as well encroach into the channel.

104. Question: RE: Section 13 50 00, Subsection 1.1.1.b. New Components on Existing Lock and Upstream Cofferdam: This subsection lists additional instruments as “new”. Please confirm if the instrumentation on the Upstream Cofferdam is existing or needs to be installed.

Answer: Clouded instrumentation on Drawing 61N852-17 must be replaced.

105. Question: RE: Section 13 50 00, Subsection 3.4.2 Inclinometer Monitoring: This subsection states manually read inclinometers are to be read once a day during the unwatering test period. Please provide the number of manually read inclinometers in the project. (We only observed in-place inclinometers on the drawings.)

Answer: There are currently no plans for manually read inclinometers. If used, they would adhere to the reading schedule in the subject paragraph.

106. Question: RE: Section 13 50 00, Subsection 3.13 Maintenance, Reliability, & Replacement. Should the anticipated rates of failures shown be applied to both existing and instruments installed as part of this project?

Answer: Yes, assume it applies to both existing and new.

107. Question: Can the contractor elect to utilize on one disposal area?

Answer: Yes, but clean overburden material must be stockpiled such that it can be easily accessed for use as backfill in the future.

108. Question: Can the blasting consultant not work for any blasting material supplier for manufacture or just the one for the project?

Answer: The Blasting Consultant may not work for the supplier of the blasting materials used on this project. The intent is for the Consultant to be an independent expert. See section 31 23 06, para. 3.4.1.
