R:08/22/01
Plan Sheet / Specification Reference= Contract Item 73, Special Provisions Section 10-1.47, Standard Plan A76 and Contract Plan Sheets 2, 3, 10 - 17.

Please provide accurate pavement differential elevations for grades, eastbound and westbound, at intersection of concrete barrier face with finish pavement grade.  This is necessary to accurately determine concrete and rebar quantification and extent of lower #13 rebar stirrups required by Standard Plan A76, Note 9, where pavement differential is 305 MM (12") or greater.  Due to variable width and variable cross slope of asphalt concrete shoulders, and because no profile grades are provided for eastbound direction Station 10+07 to 11+73, accurate pavement differentials cannot be calculated.

Q:08/15/01
R:08/20/01
Plan Sheet / Specification Reference= Reference Plan Sheets 88, 89 and 92. 

Signs 4 and 5 are noted to " . . . extend piles to top of barrier."  Please clarify if the extension is to be within the upper pedestal portion of CIDH foundation (Standard Plan S-13, Section B-B), or is the extension to occur in the lower portion, (Section A-A on Standard Plan S-13.)

  • Per REVISED STANDARD PLAN S-13 the dimension for the pile pedestal (Section B-B) is given at 2.0 m, therefor the extension is within the CIDH pile (Section A-A). The note "LENGTH INCLUDES EXTENSION OF PILE TO TOP OF THE BARRIER " refers to the type 60E barrier for Sign No. 4 and type 60C barrier for Sign No. 5.
