a. ER-227 PR-149 KM 42.8, ER-228 PR-149 KM 42.9: Borrow material is defined as having a classification of A-2-4 or better and an angle of internal friction of 27 degrees, as mentioned on pages GR-A-4 and RW-A-3, respectively. However, specification 203- 2.03(b)(1) defines the borrow material with an angle of internal friction greater than 34 degrees.

i. Could you please clarify the correct specifications for the angle of internal friction required for borrow material?

Response: SCR 203-2.03(b)(1) governs over the Contract Plans as specified in Section 104.04. Therefore, the Borrow Class B material must meet 203- 2.03(b)(1) specifications.

b. ER-220 PR-146 KM 16.4: Page RW-C-2 specifies that the material for fill behind the gabion wall is to be Selected Backfill, which has an internal friction angle of 34 degrees, effective cohesion of 0, and a unit weight of 130 pcf when moist.

i. Could you please clarify the pay item for this material?

Response: The pay item for the “Fill/Backfill” material behind the gabion wall is Borrow Class B. Refer to pay item 20300-5000, Borrow Class B, in the Bid Schedule.
