Please clarify. 11. Answer: Bid Item #14 Channel Excavation. 12. Question: What bid item does the ditch excavation and embankment that is shown on plan sheets C-18 thru C-20 go under? Please clarify. 12. Answer: Bid Item #14 Channel Excavation. 13. Question: Upon further site investigation the new 8 hog wire fence located east of the existing control structure seems to be in conflict with the new structures DS-01 and JB-01. Along with being in conflict with the relocated ditch, running west to east at the north end of the project. At the pre-bid meeting it was specifically stated that the new fence was not to be disturbed. Please clarify what is to happen with this new fence. 13. Answer: Relocation of the hog wire fence in this location is incidental to the construction of Bid Item #14 Channel Excavation. Therefore, per this addendum when bidding that item, a cost associated with relocating the hog wire fence shall be included. Measurement and Payment for the relocation of existing 8 feet tall hog wire fence with new fence fabric, posts, and concrete (as needed) shall be covered under Bid Item #14 Channel Excavation. Please refer to revised Sheet C-3A. 14. Question: In the project specifications, under Section it lists the Fabric-Formed Concrete as Riprap Fabric-Formed CNC, 10 Filter Points. This is a filter point system with 10 on center filter points that is 6 thick, however in that under 2.01 Material #7, it says Filter Points Spaced Approximately 8 Centers. With the filter points being 8 on center, the Fabric-Formed Concrete System will be 4 thick. Pay Item #48 for this material lists it as 10 Filter Points, again would be 10 on center filter points, 6 thick. The plans shows this material as 10 Fabric Formed Concrete, which could be 10 on center filter point spacing or a 10 thick, which would put the filter point spacing at 14 on center. 14. Answer: Please use a 10 filter point system that is 6 thick. The 10" (250mm) filter point provides a heavy duty mat when severe abrasion is anticipated and/or additional weight is advisable. 15. Question: On plan sheet C-17 on the left side view there is a note calling out for proposed 12 access road, on the right side view there is a call out for 15 proposed stabilized access road. Everywhere else on the plans the access road is called out to be 15 wide. Please clarify what the width of the access road is in this location. It is also confusing on the plans where the stabilized access road is being constructed and where it is not. Can consideration be made to add a bid item for stabilized access road and give the square yard quantity that is needed? 15. Answer: The width of the proposed access roads shall be 15 feet wide. Bid Item 15 shall include 20,045 linear feet of 15 wide stabilized access way and Bid Item 17 shall include 9,697 linear feet of 15 wide stabilized access way. Please refer to Exhibit D to see where the linear footages apply to the project. 16.
