SERVICES

Electrical Distribution Surveys

We carry out comprehensive electrical distribution surveys to assess the condition, compliance, and capacity of existing electrical installations. The surveys support services including detailed designs, feasibility reports and recommendations.

Condition & Compliance Assessments – Full inspection and testing of electrical systems to evaluate functionality and adherence to BS7671 and Network Rail Standards.
Load Monitoring – Analysis of electrical demand and spare capacity for future expansion or system upgrades.
Site Surveys – Coverage of depots, stations, platforms, level-crossings, line-side equipment and operational buildings to support GRIP/PACE stage feasibility and design.
Reports – Post survey reports consolidating findings to include non-compliances and recommendations.

Electrical Distribution Design

We provide electrical design services from feasibility through to detailed designs. Our designs, which include specifications, calculations and drawings, ensure safe, reliable, and efficient electrical distribution systems that meet all current British and Network Rail Standards.

Low Voltage Operational Equipment – Providing outline and detailed design solutions including:
Operational Signalling Power Supplies
Operational Telecoms Power Supplies
Track Access Safety Systems Power Supplies
Points Heating

Low Voltage Operational Equipment (M&E Plant) – Production of robust power system solutions for stations, depots, and other key assets. Cable containment & routing with production of optimised layouts for ease of installation and maintenance, fully coordinated with other disciplines.
Low Voltage Operational Equipment (Lighting – Building and Non-Building Installations) – Internal and external lighting design for energy efficiency, safety, and compliance for building applications such as stations and depots as well as non-building installations such as level crossings, footbridges, driver walkways, car parks and tunnels.
Earthing & Bonding – System design to meet safety standards and electromagnetic compatibility (EMC) requirements, inclusive of full route studies covering solutions for new and existing assets/structures.
Construction Support & Design Assurance – Technical support during build phase to ensure correct interpretation and implementation of design. Production of staging designs in support of physical works buildability

Consultancy Services

We provide electrical and mechanical consultancy across all stages of a project’s lifecycle, supporting clients with technical advice as well as guidance on standards and regulations for both early-stage feasibility or during delivery.

Standards & Compliance Advice – alignment with Network Rail Standards, British Standards and Regulations.
Feasibility and Recommendation Reports
NEEDS Analysis / Legacy Baseline Assessment Reports For Signalling Power Alterations.
Project Remits / Technical Workscope Production – client requirements are fully and comprehensively explained; project expectations are clear and concise.
Design/Project Assurance – inclusive of Inter-disciplinary interface review/management through our competent and experienced Design CRE, CEM and PE roles.

Mechanical Systems Surveys

We conduct thorough mechanical surveys across all types of rail infrastructure, helping clients understand the performance and condition of critical mechanical systems. These surveys inform projects, asset management, refurbishments, and health & safety improvements.

HVAC & Building Services Reviews – Evaluation of heating, cooling, and ventilation systems for performance, control, and compliance.
Water Distribution Systems – Survey of pipework, valves, and drainage systems in accordance with current regulations.
Lineside Pumps and Controls – Survey of pipework, pumps and controls.
Moving Bridges: Survey of mechanical bridge systems and controls.

Mechanical Systems Design

Our mechanical design services focus on delivering maintainable systems for rail facilities, plant rooms, and passenger areas. Designs are developed to meet operational needs, enhance efficiency, and ensure long-term performance.

HVAC Systems Design – Energy-efficient heating and cooling solutions tailored to occupancy patterns and building use.
Water – Hot and cold-water system design, including pipework, pumps, and sanitation.
Above Ground Drainage – Sizing and specification of foul water pipework to below ground drainage systems.
Mechanical Calculations – HVAC and water systems design utilising industry standard software.
Full GRIP/PACE Stage Coverage – Design services provided from early feasibility to detailed design and As Builts.
Coordination with Other Disciplines – Seamless integration of M&E systems with architectural and structural layouts.
