Inquiry

   1

  Q:03/30/10
R:04/07/10

Plan Sheet / Specification Reference= Item 12, HMAC, special provisions section 10-1.20

Question= Item 12, HMAC, special provisions section 10-1.20 states that the material will be governed by section 39 "Standard Process" that involves the JMF, mix approval, and verification procedure. The section also states that the "aggregate...must comply with the 3/8 inch grading".  It is common knowledge that there is no approved and verified mix design for 3/8 inch aggregate in the entire state of California.  It is not known if it physically possible to produce a 3/8 inch mix that will meet the quality requirements of section 39.  There are, however, approved mix designs with 1/2 inch aggregate.

Why don't you specify a product that can be manufactured and design the project to perform with that product?

  Q:04/01/10
R:04/19/10

Plan Sheet / Specification Reference= Items 21 & 22, 4" and 8" two component paint traffic stripe.

Question=We are advised that NONE of the many striping and marking companies operating in southern California are equipped to apply this material. The closest known applicator of this material is based in Nevada. We further understand that the advantage of this material is high performance under extremely low temperatures. Given these two factors, why complicate an otherwise fairly routine rehabilitation project in sunny San Diego, with a fairly tight time schedule, with an experiment in relatively exotic materials and methods? If the district wants to conduct a test of some interesting new fancy product, set up a test program separate from a public, competitive bid construction project.

  •   Please bid per current contract documents.
