Standard Construction Specifications Part 2 Abu Dhabi Direct

Provides overall E-Library standards for infrastructure.

Detailing required drilling muds (bentonite or polymers), shaft integrity testing, and ultrasonic logging.

Standard Specifications provide a baseline; however, projects often include "Particular Specifications" to address unique site conditions or project-specific materials not covered in the standard manual.

In alignment with Abu Dhabi’s sustainability visions, recent updates in Part 2 facilitate and govern the controlled use of recycled concrete aggregates (RCA) in road sub-bases. Utility Integration

The aggressive underground climate of Abu Dhabi—characterized by hyper-saline groundwater tables, intense ambient summer heat, and soaring sulfate concentrations—demands strict compliance with structural material criteria. Part 2 outlines precise parameters to mitigate concrete carbonation and chloride-induced reinforcement corrosion. 1. Concrete Class and Durability

Specialized application methods for protective coatings to withstand high humidity and temperature extremes. Provides overall E-Library standards for infrastructure

The current edition of the Standard Construction Specifications is the second edition, published in September 2020. Since then, there has been a continuous effort to digitize and streamline compliance. The Abu Dhabi Civil Defence Authority launched a digital reference for engineering plans in late 2025, serving as a practical guide to standardize specifications for consultants and contractors, thereby accelerating the project approval process. Additionally, the QCC has released updated Infrastructure Standards Guidelines (ISGL), which incorporate all technical circulars and aim to provide a unified approach for all users.

Chillers, Air Handling Units (AHUs), and ductwork specifications optimized for high ambient temperatures ( 46∘C46 raised to the composed with power C 50∘C50 raised to the composed with power C ambient design limits).

Part 2 mandates a "Pre-qualification mix design" 30 days prior to casting. No casting is permitted without a valid slump test (tolerance: ±20mm from design) and temperature monitoring (max concrete temp at discharge: 32°C). Compliance and Application Before submitting a work method

A significant practical component of any infrastructure project in a built environment is the management of existing utilities. The specifications, including sections from related volumes like the Irrigation Systems Technical Specifications, mandate exhaustive procedures for this. Contractors are required to use hand excavation to ascertain the exact locations of all services and cannot rely on drawing which are for guidance only. The specifications also require a minimum number of trial pits and prohibit work in any area where services have not been fully located, placing the onus and financial responsibility for this critical discovery work directly on the contractor.

For contractors, engineers, and consultants working in the emirate, understanding the nuances of these standards is crucial for project approval and successful completion.

standards are often the baseline, but the SCS provides the Emirate-specific performance and environmental adaptations. دائرة البلديات والنقل STANDARD CONSTRUCTION SPECIFICATIONS - Sign In
