Structural design of a footbridge: Difference between revisions

Latest revision as of 04:51, 29 July 2022

This case study of the structural design of a footbridge provides documents that demonstrate how a stuctural design evolves.

The documents do not refer to a real site but they are based on a bridge that was built.

Definitions of document types: see here

Documents at stages 1 and 2

Client brief
Site Information
Structural design brief - Stage 1
Options analysis
Construction Methods
Structural design brief - Stage 2
Design proposal stage - 2

Documents at stages 3 and 4

Drawings: General Arrangement Layout and typical details
Specifications
Design verification Verification report A Preliminary techical assessment report Preliminary calculations A typical caculations pack (not for a bridge)
