Engineering Stack
Explore the MARCH Engineering Stack and the services that support every stage of the asset lifecycle, from design and delivery to maintenance and optimisation.
Automation & Control Systems is one of nine capabilities within the MARCH Engineering Stack.
Our teams design, implement and support control architectures, software and integration – from PLCs and SCADA through to advanced process control, telemetry and testing – combining control engineering expertise with a practical understanding of live operations and lifecycle support.
Services range from core PLC and SCADA systems through to MES, advanced control strategies, validation, testing, digital hardware and software procurement, vendor-independent engineering and ongoing optimisation.
Effective control starts with software that reflects how the process needs to operate. PLC logic, alarm management, operator interfaces and wider system integration are developed together to create a control solution that is reliable, scalable and easier to support. The result is improved process reliability, greater operator effectiveness and better visibility across the control system.

Monitoring, control, alarms and historical data are brought together in a single view, giving operators a clearer picture of plant performance across one site or many. By combining real-time information with effective control, operators can respond more quickly to plant events and make informed decisions. The result is greater operational visibility and improved plant performance.

When reliability, safety and delivery certainty matter, telemetry provides secure remote monitoring and control of distributed assets across sites and networks. By combining telemetry technologies with robust communications infrastructure, operators gain the visibility needed to respond quickly and manage assets more effectively. The result is reduced site intervention, faster response times and a more proactive approach to asset management.

MES connects enterprise planning systems with shop-floor operations, bringing production, quality, performance and traceability into a single environment. Integrating business and control systems provides a clearer understanding of production and the insight needed to manage operations more effectively. The result is improved production efficiency, enhanced product quality and stronger regulatory compliance through real-time production insight.

APC uses multivariable control, predictive models and optimisation strategies to stabilise and optimise complex processes. By responding to changing process conditions in real time, APC enables tighter control and more consistent operation. The result is improved yield, reduced energy consumption, increased throughput and more consistent product quality.

Field-level devices including variable speed drives, actuators and sensors are integrated to provide precise control of physical processes. By ensuring equipment responds accurately to changing operational demands, organisations gain greater control over performance and efficiency. The result is improved equipment performance, enhanced controllability and lower energy consumption, helping to extend asset life.
Bespoke control systems combine hardware, software and networked technologies to meet operational requirements that go beyond standard packages. Designing solutions around specific processes and challenges ensures the functionality supports the way people work in practice. The result is a tailored control solution that supports unique operational requirements, process performance and long-term flexibility.
Detailed Design Documentation captures the information needed to build, modify and support control and automation systems effectively. Detailed system architectures, I/O schedules, network designs and software specifications provide a clearer understanding of how systems are configured and operate. By developing detailed system architectures, I/O schedules, network designs and software specifications, organisations gain improved insight into how their systems are configured and operate. The result is improved build quality, safer system modifications and simpler long-term support, helping to reduce knowledge loss.
Test Documentation provides a structured approach to validating automation and control systems throughout delivery and commissioning. Test plans, procedures and records covering FAT, SAT and site validation activities provide confidence that systems will perform as intended. The result is reduced commissioning risk, greater assurance that requirements have been met and stronger support for audit and compliance activities.
For regulated industries where compliance, traceability and verification are essential, solutions can be delivered within a validated environment that supports formal validation activities. Documentation and traceability throughout the project lifecycle provide greater confidence in system compliance and readiness. The result is reduced validation effort, stronger regulatory compliance and improved protection of product approval timelines.
Batch processes can be managed in a structured way through systems that control formulation, sequencing and execution to ensure products are made consistently and efficiently. Batch and recipe management systems provide greater control over production and changes to recipes and processes. The result is improved consistency, stronger traceability, better change control and enhanced product quality across batch operations.
Operational data is transformed into clear, role-specific dashboards that present real-time and historical performance information in an accessible format. By providing the visibility needed to monitor performance and identify trends, organisations can make more informed decisions and respond to issues sooner. The result is improved decision-making, earlier identification of operational issues and stronger support for continuous improvement initiatives.

Compressed Air Control Systems manage air generation, sequencing and demand across sites to ensure supply matches operational requirements. Coordinating equipment performance and responding to changing demand provides a clearer understanding and greater control over air system performance. The result is reduced energy consumption, improved system resilience and a more efficient air supply that aligns with operational demand.

Added Value Digital HW/SW Procurement helps source digital hardware and software solutions that align with operational requirements. Technical advice, configuration and integration support sit alongside procurement to help identify the most appropriate solution from the outset. The result is reduced procurement risk and faster deployment of fit-for-purpose solutions.

Vendor Independent Engineering provides objective support across PLCs, SCADA, HMI and industrial networks, from platform selection and design through to integration, upgrade and optimisation. Focusing on operational requirements rather than a preferred manufacturer helps ensure technology decisions remain flexible and aligned to operational needs. The result is best-fit control solutions that reduce vendor lock-in, improve system performance and support long-term scalability.
