The design of new and the renewal of existing electrical substations across the Network has been a regular design activity for the AJMS Consultants Engineers. Both AC and DC substations have been completed, comprising many individual elements including transformer bunds, rectifier plinths/housings and general compound layouts. The development of the site layouts is based on in house detailed topographical surveys.

We have completed many DDA ‘Access For All’ (AFA) schemes over the years, including the provision of new compliant access ramps, footbridges and the installation of new passenger lifts. These schemes demand much more than just engineering based knowledge owing to the complex interfaces between rail and public which requires very careful planning and consideration which must start at the design stage to ensure success.

These schemes require careful project and design management to ensure the multi-disciplinary elements are successfully co-ordinated. OLE, Permanent Way, E&P, signaling, telecoms, buildings and civil designs are closely managed to ensure programme budgets are met. Recent projects have included the design of stabling sidings and associated driver’s maintenance walkways, CET walkways, cable containment, undertrack crossings and mainline OLE and signalling interfaces. AJMS Consultants are experienced in not only the civils design elements associated with the above but also taking the lead design role, bringing together and managing the disciplines on behalf of our clients if required.

AJMS Consultants are also experienced in CSM-RA and the implications of CSM on the projects and project management through all GRIP stages.

The engineers at AJMS Consultants have been responsible for the successful design and delivery of numerous platform extensions allowing for the provision of longer rolling stock to be used. These schemes include a detailed topographical survey of the existing infrastructure to allow the design of new platform extensions, lighting, cable containment, Permanent Way alterations, and gauging checks. The restricted space and operational railway provides challenges in planning and in providing the most efficient design be this the use of bespoke or modular arrangements.

Our team have vast experience of working on level crossing projects. Whether it is a simple footpath crossing renewal or a crossing requiring the full development of an AIP ground plan, the requirements are within the capabilities of our team. The need to satisfy multiple GRIP Stages, mandatory standards across various disciplines and the unique challenges presented by the improvement of legacy crossing arrangements requires a special focus. The optimum solution is not always the most obvious solution.

With respect to all civil design and support that we provide to our clients, our team have in depth knowledge and experience of delivering projects in a collaborative model environment. Our software and infrastructure support delivery of projects in a common data environment such as Projectwise. We are therefore able to deliver to the client’s collaboration specification right through a project, from surveys, documentation creation and review through to 3D model creation.
