Inquiry #13: Following up to Bidder Inquiries #11 & #12 and Caltrans response to those inquiries...regarding K-rail specifically, OSHA requires 50' minimum clearance between loading area of blast site to non-authorized personnel (in this case traveling public on 108). The requirement states, "K-rails, barriers, traffic control systems or natural terrain shall be used to prevent entry by vehicular traffic into the loading site". Response to inquiries references Section 12 but this section makes no reference to blasting safety & temp traffic control requirements. In addition, due to close proximity of traveling public on 108, by not installing K-rail along shoulder of eastbound traffic, there's no safety measure to prevent interfacing (accidental - vehicle enters work area or material enters roadway) between public and construction operations. For bidding purposes and public safety, suggest Caltrans adds quantity for this stretch (108 along Ramp F work area, approx. 2,000') to items 10,11,12. Please consider and clarify.
Inquiry submitted 06/09/2020
Response #1:Per responses to Bidder Inquiry #10 and Bidder Inquiry #11, related to Section 19-4.04 Controlled Blasting, Section 12-4.02A(3)(c), and Section 12-4.02C(3) Lane Requirement chart as well as provided pay item #120100 Traffic Control System collectively includes requirements of contractor supplied traffic control details and payment of traffic control during blasting. As to your question about barriers per sited criteria, the area of anticipated blasting is not traversable for entry of State Route 108 traffic due to natural terrain of steep embankment or steep cut section slopes. Please bid as per current contract documents.
