Projects that do not follow these standards face fines or stoppage.
Compressive strength tests, water penetration tests, and rapid chloride permeability tests (RCPT) are mandatory prior to structural casting. Earthworks and Soil Treatment

What catches foreign contractors off guard are the "Local Appendices" attached to Part 2. These are not found in FIDIC or standard ICE specs.
: Detailed standards for subsurface investigation, soil improvement, and foundation performance. Projects that do not follow these standards face
: Total settlement (immediate and long-term) must not exceed at 100% design load. Design Load
The (specifically TR-542-2 ) primarily covers Road Structures and Utilities . While Part 1 focuses on general road works, Part 2 provides the detailed technical requirements for the supporting infrastructure and specialized structures required for transportation projects in the Emirate.

| | Why it occurs | Penalty per typical contract | |-----------|------------------|----------------------------------| | Using on-site sabkha as fill | To avoid hauling cost | Full removal at contractor’s expense + recompaction testing | | Insufficient compaction passes | Schedule pressure | 50% reduction in payment for earthworks unit rates | | No dewatering during excavation | Underestimating AD’s high water table | Stop-work order, retesting of subgrade | | Not protecting utilities | Poor coordination | Full replacement cost of damaged fiber/gas/water lines + DMT fines (AED 10k–100k) |
The document outlines strict requirements for materials to withstand high soil salinity, ambient humidity, and thermal expansion. It mandates specific chemical compositions for concrete and protective coatings to prevent premature structural degradation. Standardisation of Material Quality
Testing frequency – A minimum of 3 core samples per 2,000 m² per layer. If density falls below 96% of Marshall density, the entire section must be removed and replaced at the contractor’s expense.
