Inquiry #2: Plan sheet L-1 shows a new 8" corrugated HDPE line (irrigation conduit sleeve) at NB Loop Line Sta 528. I think the general contractor will need to be paid for "Minor Concrete (Backfill)" which is bid item #61 and "Hot Mix Asphalt(Type A)" which is bid item #53. Would you please adjust those two bid item quantities to reflect this work?

Inquiry #3: Bid Item #76 is for the removal of 320 LF of chain link fence:
1) It appears the existing fence is in the same location as the new concrete barrier between SB1 Sta. 106+89 to Sta. 110+00. If this is the case won't we need to install temporary fence in this area to secure the Caltrans R.O.W.? New bid item?
2) I think we need a detail at both Sta. 106+89 and Sta. 110+00 to detail the transition from the concrete barrier with fence on top to the existing chain link fence.

2. A fence post will be installed at 6" from the end of the Concrete Barrier and existing chain link fence will be secured to the post.
