10. Question: Plan Sheet C2.03 there are two notes about a Concrete Channel with Water Stop. On the Detail Sheet there is a Detail for Concrete Gutter and a Grouted RipRap Channel. Bid Item #13 is for Grouted RipRap Channel 275-LF. I dont see a Bid Item for a Concrete Gutter.

Response: Please see the response to question 5.

11. Question: Could you define Where the Concrete Gutter Starts & Stops as well as the Grouted RipRap Ditch.

Response: There is no concrete gutter on the project, see response to question 5.

The grouted riprap ditch starts at the existing inlet and continue to within 15 feet of

DI3-4.

12. Question: On Sheet C2.03, calls for a concrete ditch assuming Detail on Sheet C3.02 Concrete Gutter is what this is. There is no pay item listed for this work.

Response: The contractor is responsible for installation and removal of e&s controls to protect sediment laden water from leaving the site. This may consist of silt fence, silt sock, inlet protection, etc. This cost should be made incidental to the linear foot price of each applicable size storm pipe. Contractor to assume silt fence or equal bmp control to run the length of each storm pipe installation.

14. Question: Is Bid Item No. 14 work shown on Sheet C2.03 near DI 3-4?

Response: Yes that is correct. All the other vegetative channels are constructed overtop of new storm pipe and the cost of that work is incidental to the storm pipe.

However the ditch that drains into DI 3-4 and then leads into the grouted riprap channel is the vegetative channel.

15. Question: Please clarify what is meant for Bid Items No. 10 and 11 concerning the Outlet Protection. Details on Sheet C3.02 appear to be for Culvert Discharge Areas, not Wingwalls.

Response: Please see response to Question 7.
