Contractor and approved by the CO.

7 Section 401. Is a MTV required for the Test Strip(s)? Is a MTV required during placement of miscellaneous items such as turnouts or parking areas?

A MTV is required for the test strip(s). A MTV is not required for ancillary pavement placement such as turnouts and approaches.

8 Item# A0780/ Pay Item #602220-1800 calls for the concrete box extensions to be precast. The details provided on the plan sheets

T5- T13 are for cast in place concrete. Are the concrete box extension to be precast or cast in place?

Precast and cast-in-place extensions are acceptable.

9 There is no Bid Item for Temporary Concrete Barrier or

Temporary Impact Attenuators. Due to the site conditions and protection of the traveling public as well as the workers would dictate the need for these devices. The need is for either cast in place or precast (which will require a closure pour) concrete box culverts.

These items should be considered subsidiary to items of work that a contractor feels they are necessary.

10 Section 157, SWPPP. The specifications appear to be written around California requirements. The Arizona DEQ requirements for SWPPP Developer and Erosion Control Supervisor are less stringent. Mormon Lake is neither Impaired or Unique

Water. Since costs are always a concern, we suggest using local specification and standards.
