How to Specify Architectural Metal Wheel Stops: CSI MasterFormat Division 32 Guide for Architects

1. MasterFormat Classification: Section 32 17 13 Parking Bumpers

Within the Construction Specifications Institute (CSI) MasterFormat 2020 Edition, architectural vehicle restraint systems and wheel stops are classified under Section 32 17 13 Parking Bumpers (Site Improvements • Pavement Markings • Parking Bumpers) and coordinated with Section 05 50 00 Metal Fabrications.

Specifying custom stainless steel wheel stops requires precise language covering metallurgical alloy grades, passive film surface treatments, mechanical impact ratings, and BIM interoperability. This guide provides architects with a complete, field-ready CSI 3-Part Section 32 17 13 Specification Template.
