Engineering and Construction for the Electrical and Industrial Sectors

Construction

Engetecnica’s Construction Division is dedicated to delivering high-performance infrastructure projects across the electrical and industrial sectors. We provide complete solutions, from engineering to execution, with our own multidisciplinary teams and specialized equipment.

Our experienced teams — spanning Civil, Electromechanical (EMEC), and Electrical disciplines — are supported by a modern, fully equipped yard tailored to our field activities. This allows us to maintain full control over quality, deadlines, and costs.

We operate under various contracting models, including:

Electrical Installation

We deliver complete installation and commissioning of all electrical systems in high-voltage substations. Our expertise covers:

  • Switching Equipment: Installation and testing of SF6/gas-insulated and air-insulated circuit breakers, disconnect switches, and grounding switches.
  • Instrument Transformers: Installation of current transformers (CTs), potential transformers (PTs), and combined units, with accuracy class verification.
  • Busbar Systems: Assembly of rigid tubular aluminum/copper busbars and flexible cable systems with corona shields and jointing kits as required.
  • Grounding Systems: Design validation and installation of grounding grids using copper-clad steel or bare copper, with fall-of-potential and step/touch testing.
  • Protection & Control Systems: Installation and wiring of relay panels, interface panels, RTUs, and integration with SCADA and automation networks.
  • AC/DC Auxiliary Systems: Supply, installation, and commissioning of AC panels, DC systems, battery chargers, inverters, and sealed or flooded battery banks.
  • Testing & Commissioning: Includes primary injection, secondary injection, relay coordination, point-to-point checks, functional logic testing, and energization support.
  • Every system is installed to meet IEEE, ANSI, and NETA standards and is rigorously tested before energization to ensure safety, reliability, and long-term performance.

Civil Works

We provide complete civil infrastructure solutions tailored for high-voltage substation environments, including:

  • Site Preparation: Earthmoving, grading, soil compaction, erosion control, and stormwater drainage systems.
  • Access & Circulation: Internal roads with heavy-load capacity, culverts, equipment pads, and crane access areas.
  • Foundations: Cast-in-place concrete foundations for power transformers, GIS bays, circuit breakers, capacitor banks, steel structures, and control buildings. Designed for seismic, wind, and thermal loads as required by code.
  • Cable Management: Installation of below-grade duct banks, cable trenches with fire barriers, manholes, and grounding electrode systems.
  • Steel Structures: Erection of support gantries, dead-end towers, and bus support frames with precise leveling and alignment.
  • Control Buildings: Construction of pre-fabricated or block-and-mortar control buildings including HVAC, lighting, fire alarm and suppression systems, security systems, and internal raceways for power and control cabling.
  • Security & Perimeter: Chain-link fencing with barbed wire, access gates, grounding at intervals, and lighting poles for perimeter visibility.
  • All civil works are delivered in compliance with utility standards and engineered for long-term durability in demanding operating conditions.
