Inquiry #1: Per typical cross section X-1 (sheet # 2 of the plans) between PM 10.0 and PM 15.4 construction note [2] depicts performing a .40' digout and replacing it with .40' HMA-C. The typical section also shows a .10' cold plane and a .10' RHMA-G cap course (construction note [3]) being installed directly above the digout.

Is it the States' intention that the contractor must cold plane out .50' of existing asphalt and place back .50' of asphalt or grind out .50' of asphalt and place back .40' of HMA-C leaving the section .10' low until the cold plane and rubberized cap course is performed? Please Clarify your intent.

Response #2:Either method will be acceptable. Per Section 39-1.11 (page 32) a vertical joint of 0.15' is acceptable. Therefore, the Contractor may mill 0.50' and pave back 0.40'. If the Contractor chooses to mill 0.50' and pave back 0.50' of asphalt, then the additional 0.10' of asphalt will be at the Contractor's expense and not paid at item(s).

Should the bid include that length, for all purposes including determination of reinforcing steel?

Response #2:Detail is showing 3'-6'' as minimum dimension on sheet C-2. This dimension needs to adjust to suit field conditions and to accommodate the guard rail pole spacing and will be determined by the RE. Any deviations from these quantities require adjustments for payment purposes. Standard Specs section 9-1.06 may be applicable. The length used to determine the volume was 4'-5" and should be used for determining all material used.

Inquiry #4: The general contractor performing the work on the adjoining project (08-OK2404) is currently dumping his cold planed grindings in several areas of the median between the rest area and Ludlow. Is it fair to assume that the winning general contractor of Project 08-OK2504 will also be allowed to deposit cold planed grindings in the median within the limits of the new project?
