Standard Construction Specifications Part 2 Abu Dhabi ✓
While specifications are usually considered dry technical documents, the ADS Part 2 is actually quite "interesting" to industry professionals because it serves as the "rulebook" that defines the quality of the entire Emirate's infrastructure.
Here is an overview of why this section is critical, how it is structured, and what makes it unique compared to other global standards. standard construction specifications part 2 abu dhabi
Typical Technical Requirements
- Compaction: 95–98% of maximum dry density (Modified Proctor) for structural backfills.
- Material gradation: Crushed aggregates (e.g., Gabbro) meeting specific sieve analysis.
- Testing frequency: Minimum one compaction test per 250 m² or per layer of fill.
- Tolerance: Finished formation levels within ±20 mm of design.
8. Practical Recommendations for Contractors and Engineers
- Pre-construction geotechnical investigation must include chemical analysis (sulfates/chlorides) to avoid surprises in Part 2 compliance.
- Design borrow pit strategy early — approved sources are finite in Abu Dhabi (many quarries in Al Ain region).
- Conduct proof-rolling (e.g., 10-ton loaded truck) on finished subgrade before placing fill — not explicitly required by Part 2 but accepted as best practice.
- Demolition: Obtain utilities conflict map from DMT’s “Darb” system before any mechanical demolition.
- Documentation: Maintain daily compaction logs, moisture readings, and nuclear density gauge serial numbers — Part 2 requires traceability.
