Mixed Open-Plan & Private Office Administration Building – OC209
OC209 is a large single-storey modular office and administration building manufactured by Prefabex for project teams that require a combination of open-plan workspaces, private offices, meeting facilities and shared support areas within one coordinated facility.
The illustrated configuration measures approximately 24.00 × 13.80 m and organizes different workplace functions around a central internal corridor. Large shared office areas support multi-person departments, while private rooms provide dedicated space for managers, engineers, supervisors and specialist staff.
This mixed-office configuration is particularly suitable for major construction, EPC, industrial, infrastructure and remote projects where different departments require different working environments within the same site administration building.
OC209 is part of the Office Containers range by Prefabex, developed for engineering, management, administration and multidisciplinary project teams.

Flexible Project Office for Collaborative & Private Work
OC209 is designed as a complete modular project-office facility rather than a collection of identical individual offices.
Its floor plan combines larger collaborative work areas with private rooms and a dedicated meeting space, allowing the building to support both departmental teamwork and focused individual work.
Large Open-Plan Office Areas
A defining feature of OC209 is the inclusion of substantial open-plan office areas designed for multi-person teams.
The illustrated configuration includes two large shared workspaces that can accommodate multiple desks or continuous workstation arrangements.
These areas can be used for engineering, planning, procurement, document control, administration or other departments that benefit from close collaboration.
Workstation quantity, desk configuration, shared storage and circulation space can be adapted according to the size and operating style of each department.
Private Offices for Management & Specialist Personnel
In addition to the shared workspaces, OC209 includes several private office rooms distributed throughout the building.
These rooms can be assigned to project managers, department heads, senior engineers, supervisors, HSE personnel, quality managers and other staff who require a quieter or more confidential working environment.
Individual offices can be supplied with desks, visitor seating, storage cabinets and other furniture according to their intended function.
Dedicated Meeting & Coordination Room
The illustrated OC209 layout incorporates a large dedicated meeting room suitable for project coordination, engineering reviews, contractor briefings and management discussions.
The room can be configured with a long conference table, multiple seats, presentation equipment, display screens and data connections according to project requirements.
Keeping formal meeting activity in a dedicated space helps separate coordination sessions from normal day-to-day office operations.
Central Internal Circulation
A continuous central corridor provides access to the different office zones, meeting room and shared sanitary facilities.
This arrangement creates a clear separation between circulation and active workspaces while allowing personnel and visitors to reach different departments without passing through another office.
Internal circulation also provides protected movement between rooms in hot, cold, windy or rainy project environments.
Integrated Shared Sanitary Facilities
Shared sanitary facilities are integrated into the OC209 layout and positioned to serve the larger office population efficiently.
The illustrated configuration includes multiple WC compartments and washbasins grouped into dedicated sanitary zones.
Concentrating wet services in defined areas can simplify plumbing distribution, maintenance and connection during site installation.
Fixture quantities and sanitary layouts can be adapted according to projected staff numbers, local requirements and final project specifications.

Designed for Multi-Department Project Teams
OC209 is particularly suitable for projects where the organizational structure includes both larger departmental teams and personnel requiring individual offices.
Open-plan areas can support engineering, planning, administration or document-control teams, while private rooms can be allocated to managers, supervisors and specialist personnel.
This combination allows the workplace to reflect the real organization of the project rather than forcing every department into the same office format.
EPC & Main Contractor Site Headquarters
Large EPC and main-contractor projects often require office space for several disciplines working simultaneously.
OC209 can function as a central project headquarters containing management, engineering, planning, procurement, quality, HSE and administration functions within one modular facility.
The building can also be configured so that different departments expand or contract as staffing levels change during different project phases.
Purpose-Built Modular Office Construction
OC209 is manufactured as a purpose-built modular office building rather than being converted from shipping containers.
This allows the structural layout, room sizes, windows, doors, internal circulation and building services to be planned specifically around office operations from the beginning.
Depending on the required specification, construction can include a galvanized steel structural frame, insulated sandwich-panel walls and roof, durable flooring, insulated windows and doors and complete internal finishes.
Thermal Insulation & Building Envelope
Wall and roof specifications can be selected according to the climatic conditions at the project destination.
Insulated sandwich panels can use EPS, polyurethane or rock wool cores depending on thermal, acoustic, fire-performance and project requirements.
Door, window and roof specifications can also be coordinated with the required level of office comfort and environmental conditions.
Electrical, Data & Communication Infrastructure
OC209 can be supplied with electrical and data infrastructure integrated during factory production.
Open-plan workspaces can be provided with multiple workstation connections, while private offices and meeting rooms can have dedicated lighting, power and data points.
Network cabling, internet infrastructure, CCTV, access control, meeting-room equipment, emergency lighting and fire-alarm provisions can also be coordinated according to the project specification.
HVAC & Ventilation
Heating and air-conditioning systems can be designed according to room size, occupancy and destination climate.
Larger open-plan spaces, private offices and meeting rooms can be divided into separate HVAC zones where independent temperature control is required.
Sanitary areas can also be provided with dedicated ventilation or extraction systems according to the final project specification.
Office Furniture & Interior Options
OC209 can be supplied with furniture packages tailored to the different workplace functions within the building.
Open-plan office areas can include individual or continuous workstations, office chairs, filing systems and shared storage.
Private offices can be furnished with desks, visitor seating and cabinets, while the meeting room can include a conference table, presentation equipment and group seating.
Flooring, internal wall finishes, lighting and furniture specifications can all be adapted according to the required site-office standard.
Customization Options
OC209 can be adapted according to the structure and operational requirements of the project team.
Open-plan areas can be divided into additional rooms, private offices can be combined, the meeting room can be resized and additional technical, storage or document-control spaces can be incorporated.
Windows, doors, sanitary layouts, insulation, electrical systems, data networks, HVAC equipment and interior finishes can all be customized before production.
Typical Applications
- Major construction projects
- EPC contractor headquarters
- Main contractor site offices
- Infrastructure projects
- Industrial developments
- Mining operations
- Oil and gas projects
- Power and energy facilities
- Remote project offices
The combination of open-plan and private office spaces makes OC209 particularly suitable for multidisciplinary project teams with different working requirements.
Administration Building for Project & Accommodation Compounds
OC209 can operate as a standalone project headquarters or as the main administration building within a larger workforce accommodation compound.
Positioning management, engineering and administrative departments close to accommodation buildings helps create a coordinated site environment where personnel housing and project operations remain closely connected.
Dining halls, sanitary facilities and other supporting modular buildings can also be coordinated within the same overall site plan where required.
Transportation & Installation
Due to its overall size, OC209 is manufactured as multiple modular sections that are transported separately and assembled at the project location.
Installation typically includes positioning and structurally connecting the modules, sealing joints and completing electrical, data, plumbing and HVAC connections.
Transportation dimensions, lifting equipment and installation sequence should be considered during the engineering stage to support efficient delivery and site assembly.
