FOUNDATION NOTES:
1. THE FOUNDATIONS HAVEBEENDESIGNED BASEDON APRESUMPTIVE LOAD-BEARING VALUE OF 1500 PSF
PERIBC SECTION 1806. AN INSPECTOR OR SOILS ENGINEERSHALL VERIFY LOAD-BEARING VALUE CAPACITY.
2. FOUNDATIONS SHALL BEARON PROPERLY PREPARED AND COMPACTED SOILS CAPABLE OF SUPPORTING
ROTARY LIFT LOADS.
3. PROTECT EXISTING UTILITIES AND STRUCTURES (OVERHEADOR UNDERGROUND) WITHIN THE WORK
AREA AS WELL AS ANY EXISTING FOUNDATION SYSTEM(S).
4. FOUNDATIONS WERE DESIGNED UTILIZING KBCSECTION 1605 'ALTERNATIVE BASIC LOAD COMBINATIONS'
WITHOUT THE 1/3 INCREASEIN THE ALLOWABLE BEARING PRESSURES DUE TO SHORT-TERM LOADING.
5. FOUNDATIONS SHALL BE PLACED ACCORDING TO THE DEPTHS SHOWN ON THE DRAWINGS. SHOULD SOIL
ENCOUNTERED AT THESEDEPTHS NOT BE APPROVEDBY THE INSPECTOR OR SOILS ENGINEER,
FOUNDATION ELEVATIONS/DIMENSIONS MAY NEEDTO BE MODIFIED BY THE ENGINEER. NOTIFY THE
ENGINEEROF RECORD IF THIS IS THE CASE.
CONCRETE NOTES:
1. CONCRETE COMPRESSIVE STRENGTH -PROVIDE CONCRETE WITH THE FOLLOWING STRENGTHS AT THE
LOCATIONS NOTED. MIX DESIGN, SLUMP, AIR ENTRAINMENT, AGGREGATE SIZE, ETC. SHALL BE IN
CONFORMANCE WITH THE ACI 301, LATESTEDITION.
LOCATION STRENGTH (PSI@28 DAYS)
SPREADFOOTINGS...............................................................3000 PSINORMAL WEIGHT
2. REINFORCING STEEL-ASTM A615 GRADE 60.
3. FABRICATE AND PLACE REINFORCEMENT IN ACCORDANCE WITH ACI PUBLICATION SP-66, ACI
DETAILING MANUAL -LATESTEDITION.
4. PLACE CONCRETE IN COMPLIANCE WITH ACI 304. ALL CONCRETE SHALL BE MECHANICALLY VIBRATED.
5. REINFORCING SUPPORT -ALL REINFORCING SHALL BE ADEQUATELY
CHAIRED/BOLSTERED. LIFTING OR HOOK IS NOT PERMITTED.

NOTE: If more than 2 horse shoe shims are used at any of
the column anchor bolts, pack non-shrink grout under the
unsupported area of the column base. Insure shims are
held tightly between the baseplate and floor after torquing
anchors.
7. IMPORTANT: Using the horse shoe shims provided,
shim each column base until each column is plumb. If
one column has to be elevated to match the plane of the
other column, full size base shim plates should be used
(Reference Shim Kit N774-1Shim). Recheck columns for
plumb. Tighten anchor bolts to an installation torque of 110
ft-lbs. Shim thickness MUST NOT exceed 1/2” when using
the 5-1/2” long anchors provided with the lift, Fig. 6.
If anchors do not tighten to 110 ft-lbs (149 Nm) installation
torque, replace concrete under each column base. See
Figs. 6a and 6b.
NOTE: FIG. 6a and 6b were taken from drawing SPEC0476.
