EXAMPLE
Step 1
Original layout
The plan view below illustrates the original anchor channel recommendations for the typical, corner zones, and jamb conditions of a
building. Curtain wall façade is present on the south side of the building. Recommendations are as follows
• Typical zone: HAC-40 91/350 F with (2) HBC-C 8.8 F M12x60 @ 6” O.C.
• Corner Zone: HAC-50 106/300 F with (2) HBC-C 8.8 F M12x60 @ 6” O.C.
• Jamb: HAC-50 106/300 F with (2) HBC-C 8.8 F M12x60 @ 6” O.C.

Step 2
Check HAC index chart
Based on the price scale chart, HAC-50 106/300 F (unit value ≈ 0.24) is a more feasible solution than HAC-40 91/350 F
(unit value ≈ 0.26).

Step 3
Check structural feasibility for the more feasible solution
• Check structural suitability of HAC-50 106/300 F at typical conditions.
Additional feedback:
The use of a bigger channel profile does not always mean a more expensive solution. There are other factors such as
number of anchors, type of anchor, economies of scale, an others that may impact pricing.
The use of a bigger channel profile only indicates a profile with higher steel strengths. There are other failure modes that
may be decisive and are influenced by the number of anchors and bolt spacing.
It is always good practice to ensure the specified product will meet the project's schedule. For typical anchor channel
lead times, see section 2.4.
Step 4
Check if the more feasible makes sense.
• HAC-50 106/300 F is structurally adequate at typical, corner zones, and jamb conditions. It is also a more feasible solution than
HAC-40 91/350 F.
• Using one channel for the entire south face of the building simplifies the anchor channel installation as it reduces the probability
of installation errors. Therefore, change HAC-40 91/350 F to HAC-50 106/300 F.
Note: Sometimes, selecting for a more feasible solution for a specific condition may not be practical. Check if the savings justify the
potential embed layout complexities.
Step 5
Original layout
Change original recommendations for the original typical conditions. Use HAC-50 106/300 F at the typical an corner zone
conditions.
