STEP 2B - COLUMN INSTALLATION (SHALLOW FOUNDATION)
2.11 Post-Installed Anchor Bolts requirements:
A) Anchor bolts (by others) shall have an ICC-ES listing demonstrating suitability for the application.
B) Anchor bolts (by others) shall be installed in accordance with the manufacturer’s instructions and
requirements.
Note:
Chemical (epoxy) anchor bolts are recommended.
Note:
Base plate hole size may exceed anchor bolt manufacturer’s recommendations. If base plate hole
diameter is greater than bolt diameter plus 1/4”, refer to AISC Design Guide 1 for minimum washer size
and thickness recommendations.
2.12
Refer to General Arrangement Drawing for base plate hole size and location. Layout and drill holes in slab
according to anchor bolt manufacturer’s recommendations for drill bit size, depth and special inspection
requirements. Vacuum up cement dust.

2.13
Install anchor bolts (not included) according to manufacturer’s installation directions and requirements.
2.14
Refer to
step 2.4
, page 6, for proper column orientation. Position column squarely over anchor bolts and
lower into place. Secure with anchor bolt hardware (not included) according to manufacturer’s installation
directions and requirements.

NOTE:
Shallow foundation installations are for indoor applications on existing reinforced slabs that meet the
minimum required thickness throughout the required area. Refer to the General Arrangement Drawing
for these requirements. Also, the area shall be free of cracks, seams, expansion joints and walls.
Foundation requirements are based on a concrete compressive strength of 3000# per square inch. For
applications where the existing floor does not meet the requirements for the desired system, consider a
Free Standing (goal post) Monorail.
