corrected to comply with the tolerances and the Contractor shall bear any
cost of correction. Method of correction shall be approved by the
Contracting Officer.
3.2.2
Cross Sections of Shafts [and Bells]
Shall not be less than design dimensions.
3.2.3
Top Location of Caissons
**************************************************************************
NOTE: Offset of less than 76 mm 3 inchesmay be
required if the eccentric loading is critical to the
column structure.
**************************************************************************
Install with top location deviating not more than [76] [_____] mm [3]
[_____] inches from centerline locations.
3.2.4
Vertical Caissons
Install plumb within a maximum of 38 mm 1 1/2 inches for the first 3 m 10
feet and 12.7 mm 1/2 inch for each 3 m 10 feet of additional depth.
3.2.5
Batter Caissons
**************************************************************************
NOTE: Consult the project structural engineer if
lesser inclination tolerance is required.
**************************************************************************
Install not more than [2] [_____] percent from specified inclination.
3.2.6
The Center of the Caisson
Shall be established after construction is completed and the center marked
by a suitable permanent mark.
3.3
TESTS
3.3.1
Penetration Tests
**************************************************************************
NOTE: The requirement for performing penetration
tests would be based on the availability of current
information on bearing conditions at caisson
locations. At least one caisson location should
require a penetration test in each area of
substantially different subsoil conditions.
**************************************************************************
3.3.1.1
Caisson Tests
After excavation, make penetration tests in accordance with ASTM D 1586 in
the bottoms of the caissons, in locations indicated, to determine bearing
conditions.
