Scope identification, inclusions and exclusions · Lesson 2 of 4

Scope identification, inclusions and exclusions: materials, standards and design constraints

How a specification section is arranged, what three agency and university sections include and hand to others, why thickness belongs in the scope line, and how to test a specified item against AFS’s limits.

You will be able to: Name the places a flashing item can be specified, say which section owns it according to the specifications opened for this module, read a thickness table without treating a dash as a rule, and check a specified item against AFS’s published limits.

How a specification section is arranged

SectionFormat arranges a specification section in three parts: Part 1 General, Part 2 Products and Part 3 Execution.

The Whole Building Design Guide describes Part 2 as the quality of items required for the job.

Section numbers here are as printed in the agency specifications opened for this module, for example 07 60 00 Flashing and Sheet Metal.

Glossary

SectionFormat: The three-part arrangement of a specification section: Part 1 General, Part 2 Products and Part 3 Execution.
Related requirements (related work): The list inside a specification section that names the neighboring sections covering adjacent work. The VA master specification calls it Related Work; the Northwestern section calls it Related Requirements.
Through-wall flashing: A flashing named in the specifications as through-wall flashing. In the federal guide specification it is included in the applicable wall system sections, not in its sheet metal section.
Counterflashing: A flashing inserted in a wall reglet that extends down over the upturned leg of the base flashing, as the federal guide specification describes installing it (paragraph 3.1.12). That specification’s sheet metal section covers counterflashing associated with roofing systems, as distinct from through-wall flashing.
Guide specification: A model specification section with bracketed text and drafting notes for the writer to edit. Its values are not requirements for any private project.
Continuous cleat: A strip that metal edge pieces hook onto. The federal guide specification lists it as its own row in its thickness table, under the Gutters group.
Girth: The total flat width of a profile. AFS’s published maximum girth is 48 in, hems included.
