Optimal Design Strategies for Oil and Gas Worker Camp Modular Solutions

Abstract

Modular camps provide accommodation and essential services for workforces operating far from established infrastructure. Their design must reconcile building-code compliance, transport and lifting requirements, environmental conditions, worker welfare, utility constraints, and long-term operating needs. This review presents a project-specific framework for planning, designing, delivering, and operating remote workforce camps. It covers design-basis development, site planning, structural and envelope design, building services, logistics, commissioning, quality assurance, sustainability, and regulatory coordination. It also identifies standards and guidance that may inform project requirements. Because applicable rules depend on jurisdiction, occupancy, and site conditions, this article does not prescribe universal sizing values. Instead, it describes the engineering information needed to establish and verify project-specific criteria.

Introduction

Remote energy and infrastructure projects may need to house workers where permanent buildings, utilities, and public services are unavailable or uneconomic. Camps can support exploration, drilling, pipeline construction, maintenance, or decommissioning. Depending on project needs, facilities may include sleeping quarters, dining and recreation spaces, medical and administrative areas, utilities, and waste-treatment systems.

Factory-built modules can reduce on-site construction and make relocation or reuse possible. They do not remove the need for site-specific engineering. A module must function as an occupied building, remain stable and weather-tight in service, and withstand forces imposed during lifting, transport, and installation. Camp planning must also account for workforce size and rotation, local hazards, available utilities, emergency response, and the expected operating period.

A camp should be treated as an integrated systemnot simply as a group of transportable buildings. Accommodation, utilities, access, emergency arrangements, and operating procedures affect one another. Worker-accommodation guidance from the International Finance Corporation (IFC) and the European Bank for Reconstruction and Development (EBRD), for example, addresses both physical facilities and management and welfare considerations [1].

This review is intended for engineers, project managers, operators, and procurement teams. It provides a framework for developing project requirements; it is not a substitute for design calculations, professional judgment, or approval by the authority having jurisdiction (AHJ).

Scope, Use, and Limitations

The framework in this article is applicable to temporary, semi-permanent, and relocatable workforce accommodation. It is most useful during concept development, detailed design, procurement, fabrication, installation, and commissioning. It may also support operational readiness reviews and lifecycle planning.

The article is deliberately non-prescriptive. It does not establish fixed occupancy limits, ventilation rates, structural load factors, utility capacities, or fire-resistance periods. Those values must be derived from the governing code, project conditions, operator requirements, and AHJ direction. Where numerical examples appear, they are illustrative and are intended only to show how assumptions should be recorded, calculated, and verified.

From Temporary Shelter to Planned Accommodation

Early resource projects often relied on tents, improvised bunkhouses, railcars, and other temporary shelters. As industrial operations grew in scale and duration, operators increasingly recognized the need to plan accommodation alongside food, water, hygiene, medical support, and emergency services. Worker-housing guidance emphasizes that accommodation conditions and their management are part of workers health and welfare, not merely a logistics issue [1, 2].

Over time, remote camps became more organized. Some were developed as semi-permanent compounds; others were designed to move as road, pipeline, or exploration work advanced. Improvements in transport, factory production, building services, and communications made it possible to deliver more complete facilities to remote locations.

Factory-built modules can standardize dimensions and interfaces, simplifying fabrication, shipping, lifting, and future relocation. However, modular construction shifts some coordination work earlier in the project. Structural connections, service routes, transport limits, site utilities, and approval documentation need to be reconciled before fabrication begins.

Planning and Camp Configuration

1 Establishing the Design Basis

Before selecting module types or camp capacity, the project team should document a design basis. It should distinguish confirmed requirements from assumptions and identify how important assumptions will be verified. The design basis should identify the source of each requirementfor example, an adopted code, permit, operator policy, risk assessment, or project assumption. Requirements that could affect safety, capacity, cost, or approval should be resolved before procurement wherever practical.

Table 1. Example design-basis register

2 Functional Zones and Modules

A camp may include:

• Accommodation units, with occupancy and privacy arrangements determined by project policy and applicable requirements
• Dining, food preparation, and food storage facilities
• Washrooms, showers, laundry, and other hygiene spaces
• Medical and first-aid facilities
• Offices, training rooms, meeting spaces, and communications facilities
• Recreation and welfare spaces
• Electrical generation, distribution, and energy storage
• Potable-water treatment and storage
• Wastewater collection and treatment
• Solid-waste storage and handling
• Maintenance, stores, and utility workshops

The site layout should separate incompatible activities, provide safe pedestrian routes, maintain emergency access, and allow utility maintenance without unnecessary disruption to occupied buildings. The location of sleeping areas relative to noise, hazardous activities, vehicle movements, and utility plant should be considered during planning.

3 Worker Welfare and Operational Rules

Design decisions should be checked against both physical accommodation requirements and the way the camp will be managed. Relevant questions include how occupancy is controlled, how cleaning and food safety are managed, how workers report maintenance or welfare concerns, and how medical assistance is accessed.

Requirements vary by country and workforce. In the United States, for example, OSHAs temporary labor camp standard, 29 CFR 1910.142, addresses specified housing conditions and facilities within its scope [3]. It should not be assumed to replace local building, public-health, or other occupational requirements. IFC/EBRD guidance and ILO Recommendation No. 115 can provide additional reference points for worker housing, subject to project and jurisdictional applicability [1, 2].

Structural and Building-Envelope Design

1 Lifecycle Loads and Load Paths

A modular building must be designed for its full sequence of use: fabrication, lifting, transport, installation, occupancy, and possible relocation. The structural design basis should identify the governing code and the loads relevant to each stage.

Table 2. Lifecycle stages and structural considerations

Building loads may include:

• Dead and occupancy loads: module self-weight, finishes, fixed equipment, occupants, furniture, stored materials, and code-required live loads.
• Environmental loads: wind, snow, rain, seismic effects, temperature variation, and other site-specific actions.
• Transport loads: acceleration, braking, vibration, impact, and temporary support conditions during road, rail, or sea transport.
• Lifting and installation loads: lifting-point forces, rigging geometry, temporary support, uneven lifting, and potential torsion or racking.

Design values should be derived from the adopted code, project conditions, and the modules transport and lifting plan. Generic loads or multipliers are not a substitute for a documented analysis. Calculations may be supplemented, where appropriate, by finite-element analysis, connection testing, or a verified prototype lift.

Stacked modules require a defined load path through posts, frames, inter-module connections, and foundations. The design should address installation tolerances, differential settlement, lateral loads, and the effects of openings and service penetrations. Tie-downs and connections must be compatible with the structural system and the sites wind and seismic criteria.

2 Illustrative Load-Traceability Example

The following example is illustrative only. It does not establish universal factors or acceptance criteria.

Consider a module with a documented lift mass of 12,000 kg. For illustration, assume that the approved lift plan and governing structural requirements specify a dynamic factor of 1.50 and an unequal-load factor of 1.10 for a particular lifting configuration.

Static weight:

[
W = \frac{12{,}000 \times 9.81}{1{,}000} \approx 117.7\ \text{kN}
]

Illustrative design lift load:

[
F_{\text{lift}} = 1.50 \times 1.10 \times 117.7 \approx 194.2\ \text{kN}
]

This result should be recorded with its assumptions, checked against the lift plan, and verified by the responsible structural engineer. The same traceability approach can be applied to transport restraint. If, for example, the transport plan specifies a horizontal design acceleration of 0.40 g, the corresponding horizontal force would be:

[
F_{\text{transport}} = \frac{12{,}000 \times 0.40 \times 9.81}{1{,}000} \approx 47.1\ \text{kN}
]

Tie-downs and connections would then be designed using the governing transport load combinations and the projects approved restraint plan.

3 Materials, Durability, and Fire Performance

Structural materials and connections should be specified in the design documents. ASTM A992/A992M is a specification for certain structural steel shapes; it is not a universal material specification for every module member, connection, or fabrication detail [4]. Material selection must be appropriate to the design, manufacturing method, and governing code.

Corrosion protection should reflect the exposure environment, including coastal salt, industrial pollutants, humidity, condensation, and chemical exposure. Project documents should specify coating systems, surface preparation, repair procedures, and inspection requirements. Dissimilar metals and concealed moisture traps merit particular attention.

Interior finish requirements should be based on applicable building and fire codes. ASTM E84 is a test method for assessing surface-burning characteristics; its results should be interpreted in the context of the governing code and are not, by themselves, a complete fire-safety classification [5]. Fire-resistance ratings, fire stopping, smoke control, alarms, and compartmentation must be addressed separately where required.

4 Envelope and Indoor Environmental Conditions

The building envelope should be designed for the projects temperature range, wind exposure, precipitation, solar gain, and operating schedule. Insulation, air barriers, vapor control, thermal bridges, glazing, and weather seals should be coordinated to limit heat loss, condensation, drafts, and moisture damage.

Envelope design should consider complete wall, roof, and floor assemblies rather than insulation values alone. Indoor humidity and air leakage can contribute to condensation in cold-climate assemblies; hot or humid climates may present different vapor-movement conditions. Hygrothermal analysis may be appropriate where the climate, assembly, or operating conditions create elevated moisture risk.

Mechanical, Electrical, and Plumbing Systems

1 Heating, Ventilation, and Air Conditioning

HVAC systems should be sized using documented load calculations that account for climate, occupancy, building use, internal equipment, ventilation, envelope performance, and operating schedules. A single installed-capacity value per occupant is not a dependable sizing rule across different climates and building types.

The design should address:

• Required outdoor-air ventilation and exhaust
• Space heating and cooling loads
• Temperature and humidity control
• Filtration and indoor-air quality
• Kitchen, laundry, washroom, and equipment-room exhaust
• Noise and vibration limits in sleeping and welfare areas
• Equipment redundancy appropriate to the consequences of failure
• Maintainability, spare parts, and operation during extreme weather

ASHRAE standards may inform ventilation and energy design where applicable and accepted by the AHJ. For example, Standard 62.1 addresses ventilation and acceptable indoor air quality within its scope, while Standard 90.1 addresses energy efficiency for specified buildings. The project team must confirm which standards, editions, and local amendments apply rather than assume that a standard is automatically governing [6].

2 Electrical Supply and Distribution

Electrical demand depends on heating fuel, cooking equipment, water and wastewater systems, communications, occupancy, and operating schedules. The design should be based on an equipment schedule and load assessment that distinguish connected load, expected demand, motor starting, critical loads, and future expansion.

The electrical design should cover generation or utility connection, distribution, grounding, bonding, overcurrent protection, lightning protection where required, emergency power, and electrical safety. Critical loads may include life-safety systems, communications, medical equipment, freeze protection, water supply, and wastewater treatment. Backup capacity and autonomy should follow a documented reliability and risk assessment.

Installations should comply with the locally adopted electrical code. In the United States, NFPA 70, the National Electrical Code, is commonly adopted, but the locally enforced edition and amendments govern [7].

3 Water, Sanitation, and Wastewater

Water-system design begins with an occupancy and demand assessment that includes drinking, food preparation, hygiene, laundry, cleaning, and process needs. Source quality, treatment, storage, distribution, freeze protection, monitoring, and contingency supply should be defined.

Wastewater collection and treatment should be selected for expected flow, influent characteristics, temperature, operator support, discharge limits, and sludge-management options. Treatment performance and discharge permits are site- and jurisdiction-specific. The design should include maintenance, sampling, alarm response, and temporary operating plans for treatment-system failures.

Potable-water and wastewater systems should be arranged to prevent cross-connections and contamination. Applicable plumbing codes and public-health requirements should be identified during design, not deferred until commissioning.

4 Fire and Life Safety

Fire and life-safety design should consider occupancy, building arrangement, travel distances, fire separation, alarms, suppression, emergency lighting, exits, assembly areas, and access for responding personnel. Kitchens, power-generation areas, fuel storage, workshops, and accommodation buildings may present different hazards and should be assessed accordingly.

Protection requirements depend on the governing code and the AHJs interpretation. Relevant references may include locally adopted building and fire codes and NFPA 101, NFPA 13, and NFPA 72, where applicable [810]. The design must also provide for emergency notification, drills, trained personnel, and clear operating procedures.

Deployment, Installation, and Commissioning

1 Logistics and Site Preparation

Transport planning should begin during concept design. Module dimensions and mass affect route selection, permits, lifting equipment, shipping configuration, and the number of transport movements. Oversize loads may require route surveys, escort arrangements, bridge assessments, or seasonal scheduling.

Site preparation includes geotechnical investigation, grading, drainage, foundations or supports, access roads, laydown areas, utilities, and environmental controls. The installation sequence should account for crane access, temporary stability, connection work, utility tie-ins, and weather limits. A transport and lifting plan should identify module lifting points, approved rigging, lift configurations, inspection requirements, and responsibilities.

2 Interface Management

Factory-built modules can reduce work at the site but create important interfaces between the manufacturer, site contractor, utility providers, and operator. Interface documents should define:

• Structural connections and tolerance requirements
• Electrical, water, drainage, fuel, and communications connection points
• Fire stopping and weather sealing between modules
• Foundation levels and bearing conditions
• Responsibility for testing and inspection
• Documentation needed for regulatory approval and handover

These interfaces should be reviewed before fabrication. Late changes can affect openings, equipment access, transport dimensions, and code compliance.

3 Testing and Handover

Commissioning should verify that systems perform as designed and that operators can maintain them. Depending on the system, checks may include structural and connection inspections, envelope testing, HVAC balancing, electrical testing, generator and transfer-switch tests, alarm and suppression tests, water-quality verification, and wastewater-treatment commissioning.

Handover documentation should include approved drawings, equipment schedules, operating and maintenance manuals, test records, warranties, spare-parts lists, training records, and a register of outstanding items. Seasonal testing may be needed where initial commissioning conditions do not allow full evaluation.

Operations, Health, and Lifecycle Performance

Camp performance depends on more than building condition. Occupancy management, housekeeping, food safety, maintenance, security, medical response, and emergency preparedness all contribute to worker welfare and operational reliability.

A lifecycle plan should establish inspection intervals, preventive-maintenance tasks, replacement assumptions, and responsibilities for both the camp operator and equipment vendors. Particular attention should be given to filters, heating and cooling equipment, generators, water-treatment systems, wastewater plants, fire protection, roofs, sealants, and corrosion protection.

Useful performance indicators include:

• Unplanned utility outages and their duration
• HVAC availability and indoor-temperature complaints
• Potable-water quality results
• Wastewater-treatment compliance and downtime
• Energy and fuel use per occupied bed-night
• Maintenance backlog and response time
• Safety observations, incidents, and emergency-drill results
• Occupancy and room-turnover performance

Indicators should be defined consistently and interpreted alongside occupancy, weather, and operating hours. They support troubleshooting and continuous improvement but do not replace inspections or regulatory compliance.

Sustainability and Resilience

Environmental performance is influenced by the full lifecycle: materials, factory production, transport, site works, energy use, water consumption, maintenance, relocation, and end-of-life disposition. Reuse can reduce waste and embodied impacts, but only when modules are designed, maintained, and transported in ways that make reuse practical.

Potential measures include:

• High-performance envelopes and efficient HVAC systems
• Controls that respond to occupancy and operating schedules
• Heat recovery where technically and economically appropriate
• Efficient lighting and equipment
• Hybrid power systems combining generation, storage, and renewable resources where feasible
• Metering of electricity, fuel, water, and wastewater
• Water-efficient fixtures and reuse systems where permitted
• Durable, repairable materials and accessible service components
• Design for disassembly, relocation, and refurbishment
• Waste segregation and documented disposal routes

Resilience measures should reflect local hazards and the consequences of utility failure. Examples include protected water storage, backup power for critical systems, spare equipment, communications redundancy, and buildings designed to maintain safe conditions during a defined outage period. The appropriate level of redundancy should be established through risk assessment, not assumed to be the same for every camp.

Quality Assurance and Regulatory Compliance

A quality plan should be developed before fabrication and cover engineering, procurement, factory production, transport, installation, and commissioning. Typical controls include design reviews, material traceability, welding and coating inspections, dimensional checks, electrical and plumbing inspections, factory acceptance tests, nonconformance management, and final documentation review.

In the United States, ASCE/SEI 7 provides minimum design loads and associated criteria when adopted by the applicable code; the adopted building code determines how those provisions are applied [11]. ASTM material and test standards may support specific design or verification tasks, but do not replace governing building, fire, electrical, or plumbing codes.

ICC/MBI 1200 and ICC/MBI 1205 address planning, design, fabrication, assembly, inspection, and regulatory compliance for off-site construction [12, 13]. Their applicability depends on the jurisdiction and project delivery method. Other potentially relevant references include NFPA 70 for electrical installations, NFPA 101 for life safety, NFPA 13 for sprinkler systems, and NFPA 72 for fire alarm systems. ASHRAE standards may inform ventilation and energy performance. The project team should verify current editions, local amendments, and AHJ requirements for each project.

1 Illustrative Project Workflow

The following example is illustrative and does not prescribe a universal design. Consider a temporary camp planned for a remote site with seasonal road access and limited utility capacity. A project team could:

1. Confirm the operating case: Establish the workforce profile, occupancy schedule, operating period, and likely changes in demand.
2. Verify site and route constraints: Complete necessary site investigations and transport surveys before fixing module dimensions or selecting lifting equipment.
3. Set performance requirements: Document environmental loads, indoor conditions, utility availability, emergency arrangements, and applicable accommodation requirements.
4. Compare system options: Assess alternative module layouts and utility configurations against access, maintainability, reliability, cost, and future relocation needs.
5. Resolve interfaces before fabrication: Coordinate foundations, inter-module connections, service penetrations, and external utility connections among the manufacturer, site contractor, and operator.
6. Verify at defined stages: Review design documents, inspect factory production, check transport and installation arrangements, commission systems, and confirm operator readiness before occupancy.

The purpose of this workflow is not to establish fixed values, but to make decisions traceable to project requirements and verifiable evidence.

Emerging Trends

Several developments are shaping the next generation of remote camps:

• Digital operations: Building-management systems, remote alarms, and equipment monitoring can support condition-based maintenance when connectivity, cybersecurity, and local operating capability are addressed.
• Hybrid microgrids: Combining generation, energy storage, and renewable sources may reduce fuel use in suitable locations. Performance depends on resource availability, load profiles, storage strategy, and backup requirements.
• Improved modular coordination: Consistent digital models and interface standards can help coordinate building services, transport constraints, and site utilities before fabrication.
• Lower-carbon materials and operation: Energy performance, material reuse, efficient logistics, and transparent measurement can reduce lifecycle impacts. Claims should specify system boundaries and be supported by verifiable data.
• Design for circularity: Replaceable components, accessible connections, and standardized interfaces can make refurbishment and relocation more practical.

These approaches introduce their own requirements, including data security, operator training, spare-parts planning, and verification of claimed savings. They should be evaluated against the camps actual operating conditions.

Conclusion

A modular camp is both temporary accommodation and a complex engineered facility. Successful delivery depends on a clear design basis, early coordination of transport and site constraints, structural verification across the full handling sequence, reliable building services, and a plan for operations and maintenance. Worker welfare and operational management should be considered alongside physical design.

Standards and guidance provide valuable design and compliance frameworks, but their applicability must be confirmed for the projects jurisdiction, occupancy, and conditions. By treating accommodation, utilities, logistics, safety, and lifecycle performance as an integrated system, project teams can develop camps that are more reliable, maintainable, and suited to remote operations.
