QUESTIONS AND ANSWERS

Questions and Answers

1. Can you verify that the access to the core locations is limited to what can safely be transported across a narrow (3‐4 ft wide?) walkway/catwalk?

Answer: The top of the upper guide wall has a minimum clearance of 3.5 feet.

2. Will the USACE be selecting the core locations and assisting with subsurface utility (electrical conduits, etc.)/structural elements (any post tension units or rebar not to be cored) locations?

Answer: USACE personnel will be on‐site to assist the contractor with the coring location and or layout. Please refer to Table 1 listed in the scope of work for the location of cores needed at each site.

3. Are the cores located where special safety measures will be required like personal flotation devices to be warn, or are there adequate railing systems in place?

Answer: All cores taken will be vertical and along the upper guide wall at each site. The hand railing along the wall shall not be removed. Personal flotation devices can be worn but is not be required.

4. Will core segments less than 2 feet in length be acceptable to achieve the total depth of up to 8 feet.

Answer: The main objective of this project is to determine the interior condition of the upper guide wall. Internal cracking maybe present and therefore, it will be acceptable if core segments are less than 2 ft.

5. Will potable water be required for coring and making grout or can water be accessed from the river? ‐ if not, will potable water be available onsite?

Answer: On‐site potable water will be available to mix the non‐shrink grout.

6. Will electrical power be available for drilling/coring devices, and if so what are the estimated distances from power to core locations?

Answer: On‐site power sources located along the upper guide wall are limited. The contractor should account for suppling their own source of power.

7. Will there be a provision for additional grouting if a conduit or void is encountered beyond our control?

Answer: A non‐shrink grout shall be used to completely fill the core hole to the top of the wall. The non – shrink may need to be compacted within the hole to completely fill the hole.

8. Is the preferred method of coring to use single tube methods? If double tube is desired, will suitable access for a drill rig be available? I would prefer to use a drill rig and double tube coring as better samples will be obtained, but single tube may be more cost effective is access is an issue.

Answer: Minimum clearances along the upper guide wall may restrict the method of coring to be used. The contractor will be responsible for providing a drill rig if required.

9. The FBO ad leads one to believe there are only 25 cores, actually there are 50 with 10 cores at each location per the Table 1 in Item 13. Is this correct?

Answer: Please refer to Table 1 listed in the scope of work for the number of cores needed at each site.

10. Our Drilling and Field Services Division specializes in coring and difficult access drilling. Generally we are most interested in the access at each of the sites; from the Statement of Work we understand the coring would take place on the upper portion of the Guide Wall, is there any obstructions (handrail, installations, etc) that would need to be moved to access each hole?

Answer: All cores taken will be vertical and along the upper guide wall at each site. Any obstructions such as the hand railing along the wall shall not be removed.

11. Do you by chance have any photos of the site(s) to cored?

The attached pictures are from the upper guide wall at Lock and Dam No. 5.

Figure 1: Looking downstream at the river ward vertical surface of the upper guide wall at Lock and Dam No. 5.

Figure 2: Looking upstream at the top of the upper guide wall at Lock and Dam No. 5. Note: A minimum clearance between the hand rails of approximately 3.5 ft.

12. Could we use water from each site for coring or would we need to provide our own water? Likewise, are we required to capture drilling water used during coring?

Answer: River water can be used for coring.
