 Plan Sheet / Specification Reference= Item 32: IMPORTED BORROW, Special Provision Section 10-1.27 EARTHWORK 

The Earthwork specification seems to contradict itself with the following two sentences:
1) "The portion of the embankment placed between the outer edges of the shoulders of the G line and from the original ground line to the structural section shall have a R-value of not less than 10 and a SE not less than 20." 
2) "The portion of imported borrow placed within 1.5 m of the finished grade shall have a R value of not less than 10."
Is it a requirement for the imported borrow to have an SE value not less than 20? 

  • The requirement for an R-value of not less than 10 and an SE value of not less than 20 shall apply to the material placed within the shoulder limits and only from the original ground upwards. The area outside the shoulder limits and within 1.5 M of finished grade shall have an R-value of not less than 10, the additional SE requirement does not apply to this area. The remaining areas shall be accordance with Section 19 of the Standard Specifications, which applies to all earthwork.
