Inquiry #2: On Sheet X-1 the existing section is said to be .20' - 1.00' of AC and 0.00' - 1.00' of AB. Is it possible for Cal Trans to narrow these down a little bit? The means of construction for Bid Item 16 Roadway Excavation drastically changes (Cold Mill Operations vs Earthwork Operations) based on Existing AC structural sections. If additional information is not provided it is nearly impossible to have uniformly representative bids.
