structural engineering discovery and strategy
Delivered through a named design package with scope, named owner, constraints, decisions, measures, exceptions and accepted close-out for every design package.
403 · structural engineering research
structural engineering, shaped around experimentation, evidence and transparent learning.
Open Ledger is a fictional structural engineering research organisation created as Interlink Apps catalogue design 403. The page architecture translates the organisation's real operating unit — the design package — into navigation, evidence, case work, people, questions and conversion rather than relying on decorative hero content alone.

03 / Work

Case 1
A representative structural engineering engagement organised one design package around a clear brief, accountable roles and evidence that could survive handover.

Case 2
The team tested the research model under live constraints, recorded exceptions and translated every unresolved issue into a named next action.

Case 3
A recurring review converted activity into a concise decision record showing outcomes, trade-offs, ownership and what the organisation would change next.

No. Open Ledger is a fictional Interlink Apps identity demonstrating a production-grade website for structural engineering research.
Every design package carries scope, ownership, constraints, decisions, acceptance criteria and close-out evidence from the beginning.
Yes. Brand, imagery, terminology, sections and operating records can change while retaining the responsive, accessible information architecture.
