10-Office Modular Administration Building – OC205
OC205 is a large single-storey modular office building manufactured by Prefabex for project management, engineering and administrative teams that require multiple private workspaces within one organized facility.
The illustrated configuration measures approximately 14.40 × 6.00 m and provides around 10 separate office rooms arranged along a central internal circulation area, together with two integrated sanitary compartments.
The combination of larger management offices and compact individual workspaces makes OC205 particularly suitable for construction sites, EPC projects, industrial developments, infrastructure works and remote operations where several departments need to work from one administration building.

Large Modular Administration Building for Project Teams
OC205 is designed for larger project teams that require more than a small site office.
Its multi-room arrangement brings project management, engineering, supervision, administration and other technical functions together within one purpose-built modular building.
OC205 is part of the Office Containers range by Prefabex, developed for project administration, management, engineering and operational site requirements.
Approximately 10 Office Rooms
The illustrated OC205 floor plan contains approximately 10 separate office rooms of different sizes.
This allows the building to accommodate several departments and personnel categories within one connected administration facility.
Larger rooms can be allocated to project managers, senior engineers or department heads, while smaller rooms can support engineers, supervisors, administrative personnel and other technical staff.
Each office can be furnished according to its intended function with desks, office chairs, visitor seating, filing cabinets and storage units.
Management & Executive Office Options
Several rooms within the illustrated OC205 configuration provide larger internal areas and additional space for visitor seating.
These rooms are suitable for project managers, senior engineers, department heads and other personnel requiring a higher-standard private working environment.
Larger offices can be configured with executive desks, guest seating, small meeting corners, filing cabinets and additional document storage.
Offices for Multiple Project Departments
OC205 can support several management and technical functions within the same building.
Depending on the project organization, individual rooms can be assigned to project management, engineering, planning, procurement, quality control, HSE, administration, site supervision and other project departments.
The final allocation remains flexible and can be adapted to the management structure and operational requirements of each project.
Central Internal Circulation
A central internal circulation area provides access to the offices and shared facilities throughout OC205.
This arrangement separates private workspaces from common circulation and allows different departments to operate independently while remaining connected within the same building.
Internal circulation also provides protected movement between offices in hot, cold, rainy or windy project environments.
Two Integrated WC Compartments
The illustrated OC205 configuration includes two WC compartments integrated into the office building.
Providing sanitary facilities within the administration facility improves convenience for personnel and reduces dependence on separate external sanitary units during normal office operations.
Fixture quantities and sanitary layouts can be modified according to expected occupancy, project standards and operational requirements.

Designed for Larger Project Teams
OC205 is particularly suited to projects where several management, engineering and technical departments require dedicated offices within the same facility.
Bringing these teams together within one administration building can improve day-to-day coordination while maintaining separate offices for focused work and departmental organization.
This makes OC205 suitable not only as a site office, but as a complete modular administration building for medium and large projects.
Purpose-Built Modular Office Construction
OC205 is designed specifically for office use rather than being adapted from a freight container.
This allows room dimensions, windows, doors, internal partitions, electrical distribution and circulation to be planned around workplace requirements from the beginning.
Depending on the selected project specification, construction can include a galvanized steel structural frame, insulated sandwich-panel walls and roof, durable flooring, insulated doors and windows and complete interior finishes.
Thermal Insulation & Building Envelope
The building envelope can be specified according to the climate and operating conditions at the project destination.
Insulated sandwich panels can use EPS, polyurethane or rock wool cores according to thermal, acoustic, fire-performance and project requirements.
Doors, windows and HVAC provisions can also be selected according to expected occupancy, office use and local environmental conditions.
Electrical, Data & Communication Systems
A multi-room project office requires more than basic lighting and power, so electrical and data infrastructure can be integrated during factory production.
Typical systems can include office lighting, power outlets, switches, distribution equipment, data outlets and dedicated connections for computers, printers and other office equipment.
Network cabling, internet infrastructure, access control, CCTV, emergency lighting and fire-alarm provisions can also be incorporated according to project requirements.
HVAC & Workplace Comfort
Air-conditioning and heating provisions can be designed according to the destination climate, office occupancy and internal room arrangement.
Individual or zoned HVAC systems can be considered depending on the required level of temperature control and the operating schedules of different departments.
This can be particularly useful in larger administration buildings where management, engineering and support offices may operate independently.
Office Furniture & Interior Options
Individual rooms can be supplied with different furniture packages according to their intended function.
Options can include individual work desks, executive desks, office chairs, visitor seating, filing cabinets, wardrobes, document storage and other equipment required for project administration.
Interior flooring, wall finishes, lighting and furniture specifications can be selected according to the required office standard.
Customization Options
The OC205 layout can be modified according to the organizational structure and operational requirements of the project team.
Internal partitions can be rearranged to create larger management offices, smaller individual workspaces, open-plan areas, meeting rooms, document rooms or storage facilities.
Window and door positions, sanitary facilities, insulation, electrical systems, data infrastructure, HVAC systems and furniture can all be customized according to project requirements.
Typical Applications
- Large construction-site offices
- EPC project administration
- Engineering offices
- Project management facilities
- Infrastructure projects
- Industrial developments
- Mining operations
- Power and energy projects
- Oil and gas sites
- Remote field operations
Its multiple private offices make OC205 especially suitable for projects that require several management and technical departments to operate from one building.
Administration Building for Project & Accommodation Compounds
OC205 can be used as an independent project administration facility or integrated into a larger workforce accommodation or project-site compound.
Positioning the administration building close to personnel accommodation allows management, engineering and technical teams to operate close to workforce housing and daily site activities.
Dining halls, sanitary buildings and other supporting modular facilities can also be coordinated within the same site layout where required.
Transportation & Installation
OC205 can be manufactured in modular sections and transported to the project destination for assembly on prepared foundations or supports.
Installation generally includes module positioning, structural connections, joint sealing and final connection of electrical, data, plumbing and HVAC systems.
Transportation planning should consider module dimensions, site access, lifting requirements and the overall project installation schedule.
