Integrated master capstone · Lesson 3 of 4

Integrated master capstone: methods and worked application

The eight-step method run on the teaching job: flat width and limits, piece count, joints, movement, wind beside tested ratings, one maker's installation sequence, and the packet that carries every assumption.

You will be able to: Apply a documented method to the teaching job: check the profile against AFS limits, plan pieces and joints, compute movement, set wind demand beside tested ratings, and assemble the packet with its assumptions.

Videos for this lesson

What this video shows: A manufacturer's walk-through of sizing metal edge coping, materials, installation tools and ES-1 installation requirements for its own snap-on coping system. It is a different system from the Drexel cleat-and-cover coping taught in this module.

Video: Metal Snap-On Coping; R-Mer Edge Coping -- Application Excellence by The Garland Company, Inc., on YouTube. Chosen from the video's published description.

Glossary

Mold-line girth: The flat width of a profile measured to the sharp corner of each bend: the legs plus hem allowances, which AFS uses as its quoting blank.
Hem allowance: Flat material an AFS hem consumes: for an open hem twice the fold plus the gap, for a smashed hem twice the fold. The register calls it a quoting simplification, not a real bend deduction.
Splice lap: The overlap between lengths where a run is joined. AFS's per-project settings give it no default, so the specification or maker sets it.
Cleat: The strip a cover hooks over, fastened to the substrate. In Drexel's Econo Coping system it is a 22 gauge galvanized continuous cleat in 10 ft lengths.
Method A and Method B: The two ways AFS's wind tool turns strength-level pressure into a number to compare with a tested rating: times 2.0, or times 0.6 and then 2.0. The engineer of record chooses.
Assumption register: A list of every input to a job marked as given, assumed or to confirm, so no assumption travels unwritten.
