ADNOC Modular Housing Specifications, Costing and Tips on Procurement

Approving ADNOC modular housing for your project requires more than selecting a cabin size and placing your order. Fire safety regulations, space requirements, MEP compliance and Civil Defense clearance, and other considerations put a large distance between a regular portable unit and a truly field ready solution.

Incompatible units are disapproved on site, push your project schedule back and will cost you significantly more to fix than to specify in advance.

So what exactly defines ADNOC compliant workforce accommodation? It’s a housing unit manufactured to ADNOC’s specifications, covering its structure, MEP systems and other parameters – ISO container dimensions, fire-safety compliance and UAE Civil Defense approval – so the unit passes inspection and becomes operational without needing to be fixed on site.

ADNOC makes use of modular and prefabricated housing solutions, including villas and workforce camps designed by prototype to provide safe and reliable accommodation quickly at remote oil and gas locations. ADNOC-approved manufacturers in the UAE, including Al Bait Al Hadi (HPI), produce units compliant with ADNOC specs at the factory level.

This guide addresses structural specifications, unit configurations, costing factors, and the purchasing process involved in making sure the camp goes from being ordered to being occupied without any hiccups.

What are ADNOC Modular Buildings?

Modular units refer to large prefabricated buildings delivered to the building site directly. These can be individual sleeping quarters or even whole villages.

They are deployed at remote locations like Ruwais, Habshan, Bab Field, and even at sea platforms. A typical camp consists of labor accommodations, temporary offices, bathrooms, and food/mechanical facilities.

Because modular buildings are fabricated in a factory setting away from the building site, modular building saves about half the construction time of conventional building.

Dimensions and Structure Base of Containers

The ADNOC compliant accommodation consists of ISO containers as frames. The dimensions are 20 feet and 40 feet for single-room configurations and high cube configurations, respectively.

For height, we have 8 feet 6 inches for standard dimension containers and 9 feet 6 inches for high cube containers. The frame should be made of quality steel in accordance with the DIN/ISO standards and should feature reinforced flooring suitable for stacked multi-story construction, with a minimum loading capacity of 200 kg/m² for a two-storey structure.

20 ft Versus 40 ft: Fast Facts

Insulation and Wall Panel Specifications

The wall panels have to be made of certain materials. The construction of the wall panels is made of cement boards on both sides about 8 mm thick with 84 mm of EPS insulation between the boards. The density of the cement boards is about 1,300 kg/m³.

Insulation Coefficients:

• External walls: K = 0.45 Kcal/m²hC
• Partition walls: K = 0.44 Kcal/m²hC
• Roof insulation: K = 0.39 Kcal/m²hC

In the desert conditions of the UAE, where temperatures can reach above 45°C in the summer months, the ratings will decide whether the sleeping zone remains inhabitable or whether the HVAC works within its specified parameters.

MEP System and Electrical Supply

MEP compliance according to ADNOC safety and environmental standards prior to shipment from the factory by any reliable supplier is common practice. The electrical supply voltage is 240VAC 50Hz, with opto-isolated safety circuitry offering at least 1,000 VDC isolation.

The MEP work is done prior to installation; therefore, eliminating most of the risks associated with trades on site.

ADNOC Compliant Unit Configurations for Camps

Single room unit worker accommodation for Ruwais oilfield deployment is a whole different requirement compared to the 500 bed worker accommodation camp set up in Habshan. Matching the configuration to requirements before procuring saves both money and time.

20 ft and 40 ft Rooms Configuration

While 20 ft ISO units are mostly designed for single or small double occupancy rooms, 40 ft high cube units are ideal for bunk accommodation or en suite accommodation with different rooms for sleeping, bathing, and storage.

Partitioning in most cases is done in the factory by ADNOC compliant manufacturers, where you get ready-to-occupy configuration when delivered, but it is based on the manufacturer. See Container Accommodation, HPI Prefab Houses Industries.

Multiple-Storey Modular Block Design for Large Scale Camps

These units can then be stacked up to two or three storeys high. This is possible owing to the fact that the 200 kg/m² floor loading capacity specification exists.

This design concept has become a common practice for labor camps within the Western Region of Abu Dhabi, usually delivered in the form of Practical Dormitory Accommodation Containers in UAE.

Skid-Frame Based Units for Remote Locations

These skid-frame based units work well with ADNOC’s oil field deployments, which are generally in remote locations like Bab Field, where access to cranes and prepared ground might be difficult.

The Habitability and Safety Standards You Cannot Ignore

ADNOC has certain standards regarding habitability, and any accommodation facility that does not have such standards will not pass an inspection before even a single occupant moves in.

Occupancy and Sleeping Rooms Regulations

As per the UAE labor accommodation law (Ministerial Resolution No. 44 of 2022 of the Ministry of Human Resources & Emiratisation), the minimum space required is 3.0 sq. m. of usable sleeping area per laborer. ADNOC requirements could be more stringent, so check the specific standard according to your contract.

Storage space, bathroom, and corridor space are not included in the required space calculation. Cooking in sleeping rooms is not allowed; therefore, kitchens and canteens need to be erected as separate units.

Fire Alarm, Fire Fighting and Civil Defense Approvals

Fire alarm and firefighting systems, which must be approved by the Civil Defense in the UAE, include smoke detection, heat detection, manual call points, sprinklers, and emergency lighting. Wall panels and structural elements must have fire-resistant material providing 1 to 2 hours of fire resistance, safeguarding the lives of workers in isolated oil field locations. Oil field fire and gas-related equipment must also conform to shock and vibration resistance standards: 15g shock resistance for 11 ms.

The fire strategy and protection plans have to be submitted to the Civil Defense during the design phase. In case there are any changes that affect safety issues, the plan will need to be resubmitted. Practical advice can be found in Civil Defense Fire Compliance Resources.

Facilities, Access Control and Site Layout

Each bedroom must have a side table for individual use and the facility must have an access control system running on software. The site layout should be such that the ambulance access is ensured at all times and drainage, lighting, and waste services must be commissioned prior to the arrival of workers.

Why Modular Camps Have High Costs

The price range for ADNOC standard modular accommodation is wide indeed, and one square meter price means absolutely nothing.

Price Per Unit and Per Bed

Multiply these prices by the required number of beds plus facility modules, cafeteria, ablutions, and offices to estimate the preliminary capital budget without civil works.

HVAC as the Major Cost Factor

Specialized climate systems specific for the UAE are the major cost factor in modular camp costs. Top-tier HVAC increases the cost to over AED 11,000 per square meter.

Reducing the HVAC specification in order to reduce the initial investment is simply not worth it, because poor climate control in an oilfield environment in the UAE leads to serious issues that will cost much more to solve.

Costs of Construction and Mobilization

Construction time using factory-produced modules is greatly reduced. Costs for site preparation in terms of foundations, drainage, access roads, and electrical distribution are related to unit costs. Allocate these costs separately, especially in distant locations.

Procurement and Mobilization: Phases in Procuring Modular Camp Units

Knowledge of the procurement process avoids expensive errors. Omission of phases is what generates the compliance issues seen during inspections.

Regulatory Approval and Pre-Mobilization

Procurement involves initial involvement with ADNOC Group engineering standards, compliance with UAE building regulations, approval from the UAE Civil Defense, and specific municipality regulations for Western Region sites such as Ruwais.

A realistic proposal requires workers’ numbers, site location, mobilization dates, and ground conditions from suppliers. Engaging suppliers without knowledge of the regulation picture usually results in a need for substantial modification of the proposal.

Case Studies of Prefabricated Camps for ADNOC explain how regulatory conformity and factory completion accelerate mobilization.

Site Preparation

Civils that need to be in place prior to installation consist of foundations, drainage systems, electrical distribution, roads, and access for emergency vehicles.

Schedule delays due to site preparation are the most prevalent reasons for schedule overruns. Schedule and budgets are won and lost in coordinating civils and units manufacturing in parallel as opposed to sequentially.

Modular Camp Village Delivery and Commissioning Time Frame

A whole camp village can usually be delivered and commissioned in anywhere from one to three weeks following site preparation. Modular units equipped with standard fit-out of MEP systems can normally be delivered within two to six weeks of order confirmation.

ADNOC’s 90,000 m² guest house village project at Al Ruwais employed modular construction to complete entire three-story buildings in only 27 days each.

See Specialist Planning References and Case Studies for more information on larger dormitory planning.

Selection of ADNOC Compliant Supplier

The wrong choice made at the specification phase leads to non-compliance issues which would become apparent during inspection and then cost much effort and money to be sorted out.

What is meant by ADNOC Compliant & ICV Certified?

ADNOC compliant supplier designation indicates that the firm has gone through ADNOC’s technical and operational compliance procedures. ICV (In-Country Value) certification demonstrates the contribution of the supplier to the UAE economy in line with the ADNOC Procurement Policy.

Both certifications are usually required in the tender, while general certifications such as TUV alone may not suffice in the absence of ADNOC approval. Check your requirements in the tender documentation, since criteria may differ depending on the contract type. Only those contractors who have been approved in the ADNOC Supplier Hub can provide you with such equipment.

Questions To Ask Prior to Contracting

• Are ADNOC certification papers & ICV papers available with the supplier? If no, end the discussion here itself.
• Factory MEP fit-out or on-site MEP fit-out? Factory MEP fit-out ensures realistic timelines.
• What is the lead time from order to delivery including civil defense sign-off assistance?

A supplier who fails to address these questions is definitely trying to tell you something prior to contract.

It’s an employee benefit distinct from accommodation provided for the project. ADNOC provides an eligible employee with housing allowance which can be requested either as an advance interest free loan or paid as monthly allowance based on the employee’s grade, nationality and contract type – contact Human Resources.

What is the ADNOC project for 2026?                                                                             

ADNOC stated that it would be awarding about AED 200 billion (USD 55 billion) worth of projects between 2026-2028 as part of its five-year capital expenditure program covering upstream and downstream operations, with special emphasis on manufacturing locally using “Local+” approach for its suppliers.

What is PMC in ADNOC?                                                                                                      

PMC stands for Project Management Consultant, an external engineering firm appointed by ADNOC to monitor the work of EPC contractors for any projects assigned to them in terms of schedule compliance, quality control and safety requirements.

How to apply for ADNOC approval?                                                                                    

Suppliers register themselves in two steps on ADNOC Supplier Hub (SAP Ariba platform), namely Registration involving company profile, trade license and other related documents followed by Prequalification based on assessment of technical competencies against particular work groups.

Setting the Right Foundation

The decisions that determine the pass/fail outcome of an ADNOC modular camp come earlier than commissioning day – during the specification and supplier selection process.

Compare your unit dimensions and structure to ADNOC’s dimensional and structural standards. Ensure habitability is in compliance with occupancy standards and fire safety regulations. Plan ahead for HVAC and civil work costs, which will vary significantly based on these parameters rather than simple line item reduction.

ADNOC modular housing is not a commoditized purchase. The compliance criteria are detailed enough that supplier qualification becomes just as important as unit specification. Supplier qualification through ADNOC approval and ICV certification, with manufacturer production and factory MEP integration, is the supplier qualification benchmark necessary for project completion.
