Electrical, fibre and telecommunications infrastructure for mining

We integrate technical packages for mining projects, expansions and operations: OPGW, fibre, networks, remote sites, MV/LV, grounding, automation, testing and close-out documentation.

Scope, resources, qualifications and schedule are confirmed following technical review of the project.

Scope and decisions

Mining performance depends on closing interfaces before the site exposes the cost of error.

Altitude, roads, permits, HSE, camp, supply, weather windows and EPC coordination change productivity and risk. Scope must connect engineering, logistics, construction, testing and dossier from bid stage.

01

Power and installations

Substations, MV/LV, boards, routes, grounding, lighting and auxiliary systems.

  • Mine and plant
  • Camps and buildings
  • Remote-site power
02

Fibre and telecom

OPGW, ADSS, backbone, splicing, radio links, towers, networks, CCTV and field connectivity.

  • Backbones and nodes
  • Camp and security
  • Operator and integrator support
03

Automation and close-out

SCADA, telemetry, instrumentation, field integration, FAT/SAT, redlines and dossiers.

  • Signals and communications
  • Testing and commissioning
  • Acceptance documentation

Method

Work sequence

01

Prequalification

We structure corporate, tax, HSE, insurance, personnel, vehicle and reference requirements.

02

Survey

We validate site, access, altitude, services, interfaces, schedule and client conditions.

03

Engineering and bid

We close responsibilities, quantities, assumptions, logistics, output and deliverables.

04

Mobilisation

We plan personnel, equipment, camp, transport, supplies and contingency.

05

Execution and control

We work by measurable fronts with QA/QC, HSE, progress and change control.

06

Acceptance

We close tests, punch list, redlines, dossier, demobilisation and warranty support.

Required inputs

Information required to quote without hidden assumptions

Correct inputs turn a general requirement into an executable, measurable and quotable scope.

  • Location, altitude, climate and operating calendar
  • Routes, permits, inductions and access regime
  • Camp, meals, accommodation and transport
  • Technical scope and boundaries with EPC/client
  • Quantities, drawings, specifications and current revisions
  • HSE, workers compensation, personal accident, liability and rescue
  • Personnel, equipment, vehicles and age requirements
  • Materials, manufacturing, imports and storage
  • QA/QC, inspections, tests and dossier
  • Commercial terms, advance, certification and payment

Commercial engineering

What drives price and schedule

01

Logistics and permanence

Distance, altitude, camp, rosters, weather and resupply frequency define real field cost.

02

HSE and access requirements

Training, insurance, medicals, vehicles, rescue and records may become the critical path.

03

EPC and third-party interfaces

Permits, front release, engineering and third-party supplies affect productivity and liability.

04

Cash and certification

Advance, imports, storage, milestones, payment time and retention define the financial structure.

Acceptance

Deliverables and close-out documentation

The package is complete when the technical result and the supporting records can be accepted.

  • Scope and responsibility matrix
  • Mobilisation and logistics plan
  • Contractual HSE, quality and inspection plans
  • Progress, test and change records
  • Punch list, redlines and as-builts
  • Final dossier by system and work front

Frequently asked questions

Questions that change scope, price or acceptance.

Do you work directly for mines or through EPC contractors?

Both models are possible. The offer identifies who supplies engineering, materials, equipment, camp, permits, HSE, testing and acceptance.

How do you quote high-altitude work?

Using altitude, access, climate, roster, accommodation, occupational health, productivity, rescue, transport and operating-window data.

Can you take a multidisciplinary package?

Yes, provided the boundaries between electrical, fibre, telecom, automation and civil works are defined and resourced.

What is required for vendor prequalification?

Questionnaire, document list, scope, schedule, access requirements, insurance, references and procurement/technical contacts.
