In order to make key decisions early in the programme and ensure that value for money is achieved, requirements and the manner in which they are met in the design need to be fully understood.

As part of this possible trades need to be identified in order to ensure that capability requirements are met, the chosen design is suitable for construction within the constraints of available technology, and that resources and costs are available and affordable.

Due to the inherent complexity of modern assets, the process of selecting a preferred design requires the iterative process and comparison of a decreasing number of multiple design strategies in terms of:

  • Technical and performance characteristics feasibility
  • Total cost of ownership including Non-Recurring Expenditure, Unit Production Costs and Through Life Costs
  • Programme implications and design strategy risks
  • Commercial procurement strategy

Acting as a customer friend as the design evolves, we also bring the skills necessary for technical assurance of the whole asset design.


Availability, reliability & maintainability (AR&M)

Our designs reflect an understanding of the features that contribute most to the achievement of an available, reliable, maintainable asset.

  • AR&M programme management
  • AR&M data collection & analysis
  • In-service AR&M (including trials & demonstrations)
  • AR&M modelling
  • Maintenance programme development
  • Maintenance optimisation
  • Multi-disciplinary trade studies

Supportability engineering

In-service support activities are often not considered adequately during the design phase which results in the cost and duration of support activities being driven upwards. Our design teams have a wide range of experience across the lifecycle of an asset are able to consider support activities as the design is developed. Thus the design is optimized to enable support activities.

  • Through Life Management: Support Management and Planning; Supportability Assurance; Support Analysis
  • Design for support: System Failure Mode and Effects Analysis (FMEAs); Access and Removal routes; Maintenance envelopes
  • Supplier selection: Spares / Obsolescence Management
  • Through life issues: Spares ranging/scaling; Tools & test equipment; Documentation
  • Human Factors Analysis, Integration, Planning & Management

Human factors integration/engineering

Human Factors Integration (HFI) Planning and Management sees us cover: Early Human Factors Analysis; HFI Working Groups; HFI Risks, Assumptions, Issues, Dependencies, Opportunities (RAIDO) (Considerations) Register Management; HF Requirements Definition; HFI Test and Evaluation Planning.

  • Human Factors Analyses we undertake include: Task analysis; Human Performance Measurement; Workspace analysis.
  • Workspace and Crew Station Layout focuses on: accommodation of

personnel anthropometric ranges; Escape and Evacuation; environmental considerations.

Human Computer Interfaces that govern so many tasks in today’s military cover: Design for Situational Awareness; Generic Vehicle Architecture (GVA) human machine interface (HMI) Compliance; Design of decision support

Post design services and engineering

The decades of experience gained by BMT's multi-disciplined teams means that we are ideally placed to conduct design assurance activities, to support in maintenance of design intent through life and to develop system or equipment design change solutions.

We are able to provide independent engineering design services to both client and supplier organisations.  Technical assurance of our outputs is central to our methodology, supports decision making and reduces the risk of re-work and delays.

Maintaining design intent through life is a challenge and the importance is often lost in the pressures of delivering during the in-service phase. This can have serious safety implications as well as driving in-efficiencies in delivery of in-service availability, driving up in-service support costs. 

We have a full range of capabilities for provision of post-design services, ranging from development of in-service support solutions to provision of those services, including provision of design changes, authoring of technical documentation and provision of configuration management services. 


Is the asset safe or not? The importance of safety is recognized by all but the sheer complexity of a platform or asset, the number of stakeholders involved and complex regulatory regimes and underpinning processes can all undermine your confidence in the safety of an asset design or a design change to a platform.

BMT has experience of developing and applying safety management approaches under a range of safety regulation, policy and guidance, across high-hazard domains. Our approach to safety management follows the Health and Safety Executive (HSE)-recommended four stage cycle (Plan, Do, Check, Act) and combines this with best practice built from our pan-domain experience. Our technical expertise is founded upon in-depth knowledge and capability in safety and environmental regulation and management systems. We can ensure to the client a cost effective and pragmatic, compliance to regulations, standards and legislation.

Assessment and evaluation

Our experts, many of whom have been in the armed forces, guide selection with impartial advice and provide robust risk assessments, technical options, feasibility assessments, cost systems and well-defined and measurable service level agreements. 

Our in-depth knowledge of the defense environment enables us to apply cutting-edge thinking and technology solutions to complex defense projects. By not being directly involved in manufacturing or construction, BMT can provide an independent view across all activities. Our services range from supporting improvements at policy level through to assisting governments and their suppliers to respond effectively to safety and environmental issues associated with specific projects.
