ANSI/AWI 0620-2024 - Finish Carpentry/Installation
3.1 General
a) The following requirements shall govern unless a project’s?s require otherwise.
b) Should a conflict be discovered within this standard, the least restrictive requirement shall prevail.
c) When applicable, manufacturer/supplier shall verify field measurements.
d) Unless otherwise indicated, requirements apply equally to all performance duty levels/ aesthetic grades.
e) Any term used herein that is defined by the AWI Glossary uses only that definition for conformance to this standard.
f) Installer shall obtain, review, and comply with manufacturer/supplier’s documented instructions for installation. Product shall be securely attached. Contract documents regarding installation method(s) shall supersede manufacturer/supplier’s directive unless design professional’s approval to deviate is provided in writing.
g) Installer shall confirm the presence of wood blocking or metal strapping as indicated in contract documents. If not provided, installer shall seek written directives.
h) It is not the responsibility of the installer to scribe or fit to walls, ceilings, floors, or openings whose plumb, level, flat, straight, or square values exceed tolerances specified in contract documents.
i) The types of joinery used shall be consistent throughout the project.
j) Drywall and bugle head screws are not permitted for the installation of Product.
k) Installation shall comply with the Product’s aesthetic grade as specified in the contract documents.
l) Product shall be installed plumb and level within 3.2 mm [.125”] in 2438 mm [96”].
m) When factory-finished Product is cut or modified to facilitate installation, the resulting unfinished core shall be sealed prior to installation.
n) Tolerances listed for gaps and flushness apply to Product as installed.
o) Unless otherwise indicated within this standard, Product shall be installed in accordance with tolerance values set in product specific AWI Standards.
p) Unless otherwise indicated within this standard, open joints, machine marks, cross sanding (excluding turned surfaces), tear-outs, nicks, chips, and scratches are not permitted on surfaces visible following installation.
q) Natural characteristics exceeding the tolerances defined in the AWI 300 Materials (latest edition) are not permitted on visible surfaces following installation.
r) Residual marks, adhesive, and filler residue on exposed or semi-exposed faces, shall be removed.
s) Areas of installation shall be left broom clean. Debris shall be removed and disposed of in containers provided by the contractor or construction manager.
3.1.1 Measurements
a) This standard is written with the International System of Units (SI) followed by the United States customary system of measurement in brackets.
b) The system of measurement used in the project’s original contract documents and architectural drawings shall dictate which system of measurement within these standards is used for verification of compliance.
c) The United States customary measurement is typically a “soft” conversion of the SI measurement. In order to make the SI number more conceptually coherent and consistent, most conversions for less than 152.4 mm [6”] in dimension are “soft” converted to the nearest 0.1 mm. For measurements equal to or greater than 152.4 mm [6”], the “soft” value is converted to the nearest 1 mm.
d) “Inconspicuous,” when used in this standard, means not readily visible without careful inspection at a distance of:
| Premium | Custom | Economy |
|---|---|---|
| 610 mm [24″] | 1219 mm [48″] | 1829 mm [72″] |
e) Gaps and flushness between exposed components shall be tested with a feeler gauge at points where components are required to contact as indicated within this standard.
3.1.2 Special Requirements
a)?When seismic installation is required, such requirements and details shall be specified in the contract documents.
3.1.3 Environmental Conditions
a) Requirements of this standard are contingent upon maintaining proper interior environmental controls prior to, during, and after installation. See AWI 200 – Care & Storage (latest edition).
3.1.4 Manufacturer/Supplier Requirements for Installation
a) Manufacturer/supplier shall provide documented instructions for Product installation, fastening/joinery methods, instructions and fastener details for attachment to adjacent panels and/or components.
b) Manufacturer/supplier shall provide drawings indicating required location of blocking and supports. See the AWI 100 – Submittals (latest edition).
3.1.5 Default Grade Requirements
a) If this standard is referenced within the contract documents, and no aesthetic grade is specified, installation shall be executed per custom grade requirements.
