Service Overview
ELV System Design is the engineering and coordination of Extra Low Voltage systems that support a building's communication, security, safety, connectivity and intelligent operations. These systems typically include structured cabling, ICT and data networks, CCTV, access control, intercom, public address, Wi-Fi and integration with building management platforms.
At Desapex, ELV design goes beyond producing layouts and schematics. We develop a digitally coordinated ELV infrastructure that considers system architecture, equipment locations, containment routes, network connectivity, security requirements, interdisciplinary interfaces and future expansion from the beginning.
Our BIM-led engineering process allows ELV services to be coordinated with architecture, structure, electrical, HVAC, fire protection and other MEP systems before installation. This helps identify routing conflicts early, improve constructability and create reliable information for design, procurement, construction and operations.
Desapex's existing ELV capability explicitly covers structured cabling and data networks, CCTV and security integration, access control and intercom, fire alarm/security monitoring, public-address systems, Wi-Fi planning and BMS coordination.

Our Digital-First Approach
Digital Requirement Mapping
We translate user, operational, security, connectivity and technology requirements into a structured ELV design brief, system architecture and information requirements creating a clear digital foundation before detailed engineering begins.
BIM-Based ELV Engineering
ELV equipment, containment, pathways, risers and critical interfaces are developed within coordinated BIM environments, providing greater visibility into system routing, accessibility and constructability.
Multidisciplinary Digital Coordination
Our ELV engineers work alongside electrical, HVAC, fire protection, PHE, architecture and structural teams to identify spatial conflicts, optimize pathways and reduce downstream coordination issues.
Smart Building & Open Integration
We plan ELV networks with integration in mind, coordinating interfaces between ICT, security, fire alarm, BMS/IBMS, Wi-Fi and other smart building platforms to support scalable and connected facilities.
Data-Ready Digital Handover
Coordinated models, schedules, drawings and structured system information can support installation, commissioning, as-built documentation, facility management and future digital twin or smart building initiatives.
Core Deliverables
Structured Cabling & ICT Infrastructure
Structured cabling systems, data network infrastructure, telecommunications rooms, backbone connectivity, equipment locations, cable pathways and containment planning for scalable digital infrastructure.
CCTV Surveillance System Design
Camera positioning, surveillance coverage strategy, network architecture, equipment requirements and integration planning for reliable physical security and monitoring.
Access Control & Intercom Systems
Access-controlled doors, readers, controllers, intercom devices and security communication infrastructure designed around user movement, security zones and operational requirements.
Public Address & Voice Communication
Public address, background music and voice communication infrastructure designed for effective communication across buildings and facilities.

Fire Alarm & ELV Interface Coordination
Coordination of fire detection and alarm interfaces with ELV, security and building management systems to support integrated life-safety operations.
BMS / IBMS Integration
Coordination between ELV systems and building management or integrated building management systems to create connected monitoring and control environments.
Security System Integration
Integrated planning of surveillance, access control, intercom and associated security technologies within a unified building security strategy.
Codes & Standards
ELV Design Aligned with International Standards
Desapex develops ELV and low-current system designs considering applicable project requirements and standards, including:
TIA | ISO | IEC | NBC / NBCS | NFPA | BS | EN
Why Choose Desapex
BIM-First Design & Coordination
Our ELV systems are developed within coordinated digital environments, allowing designers and project teams to visualize routing, resolve interfaces and validate space before construction.
ELV does not operate independently of electrical, fire, HVAC, architectural or building management systems. Desapex's multidisciplinary engineering model enables these interfaces to be resolved within one coordinated workflow.
ISO 19650-Led Information Management
Desapex applies structured BIM and information-management processes aligned with ISO 19650 principles, improving consistency, collaboration and control over project information. Desapex's MEPF material identifies the company as certified in ISO 19650-1 and ISO 19650-2 for BIM and information-management processes.
Design for Lifecycle Value
We consider maintainability, scalability, future technology requirements and operational use not simply construction-stage installation.
Smart Building Integration Capability
Our wider expertise across ELV, electrical engineering, BIM, IBMS, smart buildings, automation and digital twins enables us to plan technology infrastructure that can evolve with the building.
Global Digital Engineering Delivery
Desapex combines engineering expertise and technology-enabled delivery to support complex projects and multidisciplinary teams across geographies.
