FORM & FUNCTION

What this form means

This reference arch uses columns at both ends to support a curved beam rising toward midspan. Set its high point, lower edges and membrane tension direction together with vehicle clearances and drainage; other support layouts require separate design.

01

Crown clearance and low edges

02

Joints between repeated units

03

Drainage on both sides

SITE FIT

Where it fits

Linear parking areas or routes where repeated arched units can create a coherent edge.

DESIGN CHECKS

What to check in design

Check whether arch feet take up bays, whether runoff reaches footpaths, and how joints and drainage work across repeated spans.

COMPARE OPTIONS

How it differs from neighbours

A basic arch is set around the primary parking cover, without the rear extension or visible rods that define its variants.

QUESTION & ANSWER

A common planning question

Does this reference arch use columns at both ends?

Yes. The drawing depicts an arch with supports at both ends. If the site allows only central or one-sided columns, compare a different structural and foundation scheme.
