 constructed according to the above-mentioned plans, profiles, cross sections, 

 and drawings, which shall be recognized as a part of these specifications. Any 

 variation therefrom which may be required by the exigencies of construction

 grubbed up so that no part of them shall be within six (G) inches of the sur- 

 face of the ground or within eighteen (18) inches of the surface of the 

 subgrade.
