Our design teams work across the full project lifecycle in line with the RIBA Stages to provide early feasibility and concept development through to detailed design, technical coordination, commissioning support and as-built documentation. We place equal importance on compliance, performance, safety, sustainability and buildability, ensuring designs are practical, coordinated and deliverable.

Design Led by Delivery Experience

A key strength of our design capability is that it is informed by decades of installation and project delivery experience. Our designers work closely with project managers, engineers and site teams, ensuring designs are grounded in practical reality and aligned with construction methodologies, sequencing and programme constraints.

This delivery-led approach supports the core objectives of the Building Safety Act, particularly around design responsibility, competence and safety-by-design, reducing foreseeable risk at source and supporting safer construction and occupation.

We routinely work on technically demanding projects requiring careful coordination between multiple disciplines, stakeholders and operational constraints, bringing clarity and control to the design process while supporting the requirements of CDM dutyholders, including Principal Designers and Principal Contractors.

Electrical Design Services

Our electrical design services cover the full spectrum of low and high voltage systems, providing safe, resilient and efficient power distribution solutions.

Electrical design services include:

• LV and HV system design
• Load assessments and capacity planning
• Incoming supplies, substations and switchgear
• Power distribution, small power and specialist supplies
• Lighting and lighting control systems
• Emergency lighting and life safety systems
• Earthing, bonding and lightning protection coordination
• Discrimination and protection studies

Mechanical Design Services

Our mechanical design capability supports efficient, compliant and sustainable building performance across a wide range of environments.

Mechanical design services include:

• HVAC systems (heating, cooling and ventilation)
• Plant room design and equipment selection
• Hot and cold water services
• Above-ground drainage
• Building Management Systems (BMS) integration
• Energy efficiency and system optimisation

Fire & Security Design Services

Through our specialist fire and security design capability, we deliver compliant, integrated life-safety and security system designs for complex buildings.

Fire and security design services include:

• Fire alarm and detection systems
• Voice alarm and voice evacuation systems
• Aspirating detection
• Emergency voice communication systems
• CCTV, access control and intruder alarms
• Integrated fire and security platforms
• Cause and effect strategies and evacuation modelling

Fire and life safety designs are developed with a strong understanding of occupancy, building use and risk profile. Particular emphasis is placed on clear cause-and-effect strategies, false alarm management and evacuation logic, supporting both CDM risk reduction and the Building Safety Act’s requirements for safe evacuation and building control.

Data & Telecommunications Design

We design robust, future-proof data and telecommunications infrastructure to support modern, connected buildings.

Data and telecoms design services include:

• Structured cabling systems (copper and fibre)
• Network architecture and capacity planning
• Cabinet and containment layouts
• Segregation and resilience strategies
• Integration with security, BMS and smart building systems
• Warranty-compliant design for manufacturer certification

Designs consider segregation from power systems, fire stopping, access for maintenance and long-term system integrity. This supports CDM requirements to eliminate or reduce foreseeable risk and aligns with the Building Safety Act’s emphasis on coordinated, well-documented building systems.

Design Coordination and Technical Assurance

Complex projects require strong technical coordination. Our design teams work closely across disciplines to manage interfaces between electrical, mechanical, data, fire, security and energy systems.

We provide:

• Multi-disciplinary design coordination
• Clash avoidance and spatial coordination
• Technical reviews and value engineering
• Compliance checking and assurance
• Support through commissioning and handover

This coordinated approach supports the “golden thread” principles introduced by the Building Safety Act, ensuring design information is accurate, consistent and suitable for handover, operation and future modification.

Health, Safety and Compliance in Design

Health and safety is embedded in our design process. In line with CDM Regulations 2015, we proactively identify, assess and eliminate or reduce foreseeable risks through design wherever possible.

Our designs address:

• Electrical and mechanical safety
• Safe installation sequencing
• Access and maintenance safety
• Fire and life safety considerations
• Compliance with current legislation and standards

By considering safety throughout the design lifecycle, we support safer construction, safer buildings and safer long-term operation, in line with both CDM duties and the Building Safety Act.

Experience You Can Rely On

With over 30 years’ experience delivering complex projects, our design capability is underpinned by a deep understanding of how buildings function in the real world. We have supported projects subject to increasing regulatory scrutiny, evolving safety legislation and heightened accountability.

Our experience allows us to navigate complexity, manage risk and deliver designs that meet modern legislative expectations while remaining practical, buildable and efficient.

Documentation & Handover

What design documentation do you provide?

We provide clear, coordinated design documentation, including drawings, specifications and technical information suitable for construction, commissioning and long-term operation. This supports compliance, maintenance and asset management.

Do you support commissioning and handover?

Yes. We support commissioning, technical validation and as-built documentation, ensuring systems are handed over safely, clearly and in line with regulatory expectations.

Working With Evans Electrical

Who do you typically work with during the design process?

We work collaboratively with clients, consultants, Principal Designers, Principal Contractors, facilities teams and system specialists to ensure designs are aligned with project objectives and operational needs.

At what stage can you get involved?

We can support projects from early feasibility and concept design through to detailed design, construction support and handover.
