Writing proposals for Swiss Federal Roads Office (ASTRA) branches in August 2026 requires meeting noticeably stricter requirements for structural verifications and traffic routing. Outdated proposal templates from 2022 increasingly trigger formal point deductions.
1. ASTRA 11001 & 12000: Verifying Cross-Section Dimensions
Generic references to standard profiles are no longer accepted. ASTRA now requires precise clearance dimensions and night closure stage schedules directly in the technical tender report. An incorrect dimension on page 41 can disqualify an entire submission.
2. Clear Separation: Federal vs. Cantonal Standards
For junctions connecting to cantonal roads, municipal guidelines (such as City of Zurich TBA Normalie 103) govern rather than federal ASTRA codes. Mixing both jurisdictions creates severe compliance risks.
- ✓Always check the title page of the guideline for valid edition numbers (e.g., Edition 2022 V4.00).
- ✓Never copy structural assumptions from past archives without verifying current ASTRA directives.
- ✓Back every single technical metric with document name, edition date, and exact page citations.
