JSM Group delivers full-turnkey infrastructure services across energy, telecommunication, data centre and renewable energy projects.

1. Identify client needs: JSM works with clients from early concept and feasibility to fully define infrastructure requirements (e.g., power connection, fibre rollout).
2. Design & planning: We develop technical designs, route assessments in-house.
3. Construction and installation: Teams execute civil engineering, ducting, cables, substations, fibre networks etc.
4. Commissioning & energisation: We manage the hand-over to network operators or clients, ensuring systems are ready and compliant.
5. Maintenance & ongoing support: We provide fault-response, maintenance and inspections to ensure long-term performance and reliability.

JSM brings decades of experience, integrated in-house capability, a trusted safety and sustainability culture, and a “one-stop” delivery model that covers all stages from design to maintenance.

1. Proven track-record: JSM has been operating since 1998 and has delivered many major utility and telecoms
projects.
2. Full in-house capability: We control civil & installation works reducing the need for multiple contractors.
3. Client-centric delivery: We aim to collaborate, cut through complexity, and provide clear single-point contact for clients.
4. Future-ready & scalable: We support emerging markets (e.g., data centres, renewables) and are equipped for large-scale, complex infrastructure programmes.

JSM ensures safety, quality and sustainability by embedding these values into its core operations, executing rigorous management systems, using innovative methods to reduce impact, and committing to long-term social and environmental
goals.

1. Rigorous systems: We implement health, safety, environment and quality (SHEQ) frameworks and governance across all works.
2. Innovation in delivery: We develop techniques (e.g., non-intrusive cable extraction) to reduce environmental impact and disruption.
3. Supply chain collaboration: We work closely with suppliers to ensure compliance with ethical, safety and sustainability standards.
4. Long-term commitment: We report on metrics (carbon, waste, biodiversity, social value) and set road-maps for future improvement.

JSM provides end-to-end utility and civils support for data centre developments, offering power connections, fibre networks, enabling works and long-term asset support.

1. Early feasibility & routing: We assess constraints, utility availability, land access and programme impacts to help define the optimal delivery strategy.
2. Design & coordination: Our in-house engineers prepare technical designs, cable routes, civils layouts and coordinate with telcos and other third parties.
3. Civils & utility construction: We deliver ducting, joint bays, chambers, cable routes, power infrastructure and fibre connectivity.
4. Interface & commissioning: JSM manages energisation, testing, fibre light-up and all interactions with network operators.
5. Ongoing operations support: We provide reactive and planned maintenance to keep data centre critical infrastructure resilient and compliant.

JSM integrates multiple utility disciplines into one coordinated programme, reducing disruption, accelerating delivery and ensuring compliance across all networks.

1. Single-team coordination: We bring all utility strands (power, gas, water, telecoms) under one delivery structure.
2. Integrated design: Our teams produce aligned utility layouts, clash detection, route optimisation and scheduling to minimise re-work.
3. Specialist civils execution: We deliver trenching, ducting, chambers, reinstatement and utility installations with
multi-skilled crews.
4. Stakeholder management: JSM handles approvals, traffic management, permits, land access and coordination with asset owners.
5. Testing, validation & handover: We ensure all networks are certified, documented and ready for client operation.

Through careful planning, low-impact construction methods and strong traffic management, JSM reduces disruption to communities and stakeholders.

1. Pre-planning & impact assessments: We model potential impacts and design programmes that minimise road occupancy and community disturbance.
2. Innovative low-impact techniques: Methods such as trenchless installation and non intrusive extraction reduce surface disruption.
3. Clear communication: JSM provides advance notifications, signage and community updates to keep affected parties informed.
4. Efficient traffic management (TM): Our TM teams plan diversions, phasing and rapid reinstatement to maintain safe, flowing traffic.
5. Rapid response & reinstatement: We restore surfaces and resolve issues quickly to reduce the duration of public impact.

JSM offers a fully integrated fibre delivery solution-from survey and design through to civils, cabling, splicing and maintenance-providing faster, more reliable rollout.

1. Survey & planning: We conduct desktop and on-site surveys to define routes, existing duct capacity,
risks and programme constraints.
2. Design & engineering: JSM develops fibre network designs, splicing plans, PON layouts and chamber schedules in-house.
3. Civils & duct installation: Our teams deliver ducting, chambers, poles, reinstatement and enabling works at speed and scale.
4. Fibre installation & testing: We manage cable pulling, splicing, OTDR testing and quality assurance.
5. Network operations support: JSM provides ongoing maintenance, fault response and upgrades to protect long- term performance.

By reducing carbon impact, promoting circular economy practices, minimising waste and adopting advanced low-impact construction methods.

1. Carbon reduction planning: We evaluate construction methods, logistics and materials to minimise emissions.
2. Low-impact engineering: JSM uses trenchless techniques, non-intrusive cable removal and smart logistics to
reduce fuel use and disruption.
3. Responsible sourcing: Suppliers are assessed for environmental performance, ethical standards and
sustainable materials.
4. Waste management & recycling: We prioritise recycling, responsible disposal and reuse opportunities to cut waste volumes.
5. Monitoring & reporting: JSM tracks carbon, waste and social value metrics to demonstrate measurable
sustainability performance.
