3 D. Pre-Bid Meeting Questions # Question Response Initial Response: The County will take a look into it. 1 Any chance of changing the blue stone #57, #6 to local materials? 2 Where are the boring logs in the documents? Further Clarification: Per MDE Chapter 5 of the Maryland Stormwater Manual, ASTM DD48 type 4, 5, or 6 stones (AASHTO Nos. 4, 5, or 6) may be used. Stone sizes smaller than Type 6, including 67 s, are not to be used as the gravel media of the submerged gravel wetlands. Initial Response: They should be in the Stormwater Management Report. We can provide you a copy in an addendum. The County obtained a waiver from the Soil Conservation District to not have to go through Pond Code So you got a waiver from the Soil Conservation District to not have to go through Pond Code 378, which means? We will go through the clay core trench when we install the outlet pipes? Further Clarification: Two separate Soil Investigations have been completed. See Attachment A and Attachment B for further detail. With the waiver the core trench is not affected by this project. Correct. The Contractor will remove the clay core trench and restore the clay core after the installation of outlet pipes. 5 Is there an MOT plan for the road? Use the State Highway Administration (SHA) standard detail included within the solicitation. 6 Disposal of material? Do you have a site for that or is it the Contractor s responsibility?
