Peer review and constructability · Lesson 3 of 4

Peer review and constructability: methods and worked application

A six-step review method, then a constructed 62.5 ft parapet run worked through it: how many pieces, where the joints go and how far each span moves, why one cap is too wide, and why the narrower 40 in cap still fails in 16 ga.

You will be able to: Apply a six-step documented review method to a constructed parapet coping run, recording the documents, assumptions, units and evidence for four findings: piece count, joints and movement, flat width and thickness.

A six-step documented method

The documented method has six steps: collect the documents and name their versions; mark every interface; check numbers against stated sources; log each finding; hold the preparatory meeting; close the findings.

It is this module's working method, built from NIBS, UFGS and AFS practice, not a published standard.

Glossary

Preparatory phase: In UFGS 01 45 00, the meeting held before work starts on each definable feature of work, after required documents and materials are approved and on site, to review the drawings, specifications, shop drawings and field measurements.
Finding log: This module's working term for the written record of each review finding: location, reason, evidence, severity and owner. UFGS 07 60 00 asks that actual quality control observations and inspections be documented.
Splice lap: The overlap where one piece joins the next along a run. In AFS limits it is a per-job setting with no default, so each drawing has to state it; a lap shortens what each piece after the first adds to the run.
Flat width (girth): The width of the flat blank a profile is formed from, hems included. AFS limits it to 48 in, the width of the sheet, and blocks a profile over that.
