QCD Engineering Services
Power.Connect.Control.
Three specialist disciplines delivered as one coordinated system—from engineering and supply through testing, commissioning and handover.
Integrated technical scope
Every system considered.
Every interface coordinated.
The building does not experience power, security and automation as separate packages. It experiences one operating environment.
QCD coordinates electrical, low-current and smart-building systems across the complete project lifecycle. The result is a clearer technical workflow with one contractor responsible for interfaces, testing and delivery.
Our scope is built around reliable distribution, accurate connections, centralized visibility and documented performance.
Core capabilities
One technical stack.
Select a discipline to see how QCD powers, connects and controls the built environment.
Power infrastructure
Reliable power,
coordinated end to end.
QCD implements the infrastructure that distributes electrical power through a project, coordinating major equipment, cable management and protection systems through installation and testing.
- 01Medium-voltage systems and substations
- 02Transformers, RMUs and switchgear
- 03Low-voltage switchboards and distribution
- 04Cable trays and cable management
- 05Grounding and lightning protection
Connected facilities
Safety, security
and communication.
Facility technology is coordinated around operational requirements, with attention to devices, control points, communications and the interfaces that support dependable daily operation.
- 01CCTV surveillance systems
- 02Card and biometric access control
- 03Addressable and conventional fire alarm
- 04Cat6 and Cat6A structured cabling
- 05Fiber-optic infrastructure
Centralized operation
A building that
can be understood.
QCD connects building systems in a centralized operating environment, improving visibility, control and coordinated performance across energy, HVAC, lighting and connected assets.
- 01BACnet and Modbus integration
- 02Energy management and sub-metering
- 03HVAC and lighting integration
- 04Centralized SCADA systems
- 05Operational dashboards
Electrical systems
From incoming power
to final distribution.
Major electrical components are delivered as one coordinated infrastructure, supporting reliable power distribution and connection with the remaining facility systems.
Medium voltage
Power at project scale.
Implementation of substations and the major equipment required for project power distribution in line with approved engineering designs.
- Substations
- Transformers
- Ring main units
- Medium-voltage switchgear
Low voltage & distribution
Structured to perform.
Low-voltage distribution and organized cable infrastructure coordinated through installation and technical testing.
- LV switchboards
- Distribution systems
- Cable trays and management
- Grounding and lightning protection
Low-current systems
Connect people, information
and building safety.
Structured cabling
Cat6, Cat6A and fiber-optic infrastructure form an organized technology backbone for facility operations.
Monitor. Identify. Manage.
CCTV surveillance and card-based or biometric access control designed around facility operations and coordinated control points.
Accurate connections matter.
Addressable and conventional fire alarm systems delivered with attention to connection accuracy and dependable system performance.
BMS & building automation
See the building.
Control the whole.
Multiple systems come together through centralized supervision. QCD integrates energy management, metering, HVAC, lighting and operational dashboards to strengthen visibility and control.
Integrated execution
Designed together.
Delivered together.
One technical program carries each system from engineering intent through verified operation.
Engineering
Load calculations, single-line diagrams and BMS control logic.
Procurement
Materials and equipment through approved vendors.
Installation
Cable management, panels and devices coordinated on site.
Validation
Continuity, insulation, signal and point-to-point testing.
Commissioning
Live scenarios and client-witnessed operation.
Handover that holds together
Commissioned.
Documented. Ready.
Technical close-out includes the information needed to understand, operate and maintain the delivered systems.
Project environments
Capability shaped
around operation.
The system mix changes with each environment. The need for precise coordination remains constant.
Commercial
Office towers: LV switchgear, structured cabling, fire alarm, access control and BMS for HVAC.
Industrial
Factories and warehouses: MV substations, power distribution, CCTV and energy monitoring.
Infrastructure
Public facilities: redundant power, low-current systems and remote BMS supervision.
