section 1, page 5 of 16, 4.4…

section 1, page 5 of 16, 4.4.3.1 title was repeated, need to delete the latter one.

page 6 of 16, section 5.5.3, allow more of the voids seems have little use. Since void slab rarely has deep section. 

section 6.9 this should be consulted with MTO foundations.

section 2, page 13 of 46, section 2.4.5, paragraph 1, maybe non-reduction only apply to overpasses. when major highway with high speed underneath, the 10mm extra cover definitely helps.

section 5, page 11 of 15, could just use MSE, to avoid repeating. it is easy to understand. using interchangeable is wasting typing efforts.
