11.6 ANCHOR CHANNEL SPECIFICATIONS
Specifier Note: This specification is intended to address the use of cast-in anchor channel for safety-related applications, such as
structural connections, earthquake bracing, guard rails, mechanical and electrical equipment support, piping and ductwork support
and bracing, cladding, and façade connections, or rebar doweling.

MINIMIZING FIELD FIXES OF CAST-IN ANCHORS
Depending on the amount of entrapped air, the field fix for the
anchorage may vary from a simple patch with high strength
non-shrinkable grout, installing post-installed headed rebars,
or re-pouring a large amount of concrete. The field fix becomes
more cumbersome and costlier for areas where anchors are
highly loaded and reinforcing bars are used.
To avoid/minimize the number of conditions with entrapped air
at the anchorage zone, be proactive. During pre-construction
meetings, discuss the following with the concrete contractor:
a) Require concrete consolidation at each anchorage point (the GC
will thank you later!). Add extra emphasis on heavily reinforced
zones, congested areas, confined spaces, areas with minimum
reach, and zones where the formwork prevents visibility.
b) Share the best practices and make sure the field personnel
know to consolidate the concrete.
