Core services
Control engineering without the gaps between disciplines.
TBC supports the full control-system lifecycle, joining the functional requirements, detailed design, software, panels, communications and site delivery into one coherent package.
SCADA & HMI
Clear operator interfaces, alarm handling, trends, data capture and system visibility without unnecessary complexity.
Explore the serviceControl-panel design
Electrical schematics, panel layouts, I/O, terminals, cables and technical information prepared for manufacture and site delivery.
Explore the servicePower-management systems
Controls for generators, mains supplies, PV, BESS, ATS arrangements, synchronising, load shedding and resilient operation.
Explore the serviceFunctional design
Control philosophies, FDS documents, cause-and-effect schedules, I/O schedules and interface definitions that remove ambiguity.
Explore the serviceFAT, SAT & commissioning
Structured testing, fault finding, site integration and handover support with results recorded against agreed requirements.
Explore the serviceProject lifecycle
Support from the first control discussion to the final site test.
TBC can take a defined package or fill the engineering gap within a wider contractor or client team.
Define
Confirm scope, interfaces, operating philosophy, responsibilities and acceptance criteria.
Design
Produce controlled functional, electrical, network and software design information.
Develop
Build PLC, SCADA and HMI applications with structured backups and revision control.
Test
Verify I/O, sequences, alarms, communications and failure modes before site.
Deliver
Commission, close out changes and provide the information needed for handover.
Technical capability
Practical engineering that considers the whole system.
Control systems often fail at the boundaries: between the PLC and switchgear, electrical design and software, generator and mains control, or the specification and what is physically installed.
- Clear definition of client, contractor and vendor interfaces
- Design documents written for approval and subsequent testing
- Software structured for diagnosis, change and long-term support
- Panel and site constraints considered before implementation
- Testing planned around real operating and failure conditions

Industries
Flexible support for contractors, manufacturers and end users.
TBC is suited to projects where dependable controls, electrical integration and clear technical ownership matter more than a large consultancy overhead.
Manufacturing & process
Machine, plant, utility and process-control systems requiring structured PLC, HMI and commissioning support.
Energy, buildings & infrastructure
Power-management, generator, distribution and resilient-control projects with multiple equipment interfaces.
Switchgear & panel manufacturers
Specialist controls, schematics, software, FAT and site engineering that integrates with the manufacturing programme.
Electrical & M&E contractors
A defined control-system package or targeted engineering support where the wider project team needs additional capability.
Have a control-system package that needs technical ownership?
Share the current scope, drawings or specification and TBC can help define the engineering required to take it forward.
