Services

Industrial electrical engineering

From existing-plant assessment and detailed design through installation and commissioning.

LAMAEL develops electrical engineering for new industrial installations, expansions and revamping projects. Solutions are designed by a team that also understands the next stages: construction, installation, connection, testing and commissioning.

Implementation of the electrical infrastructure for an industrial technology laboratory

Engineering informed by field experience

What differentiates our approach from a conventional design office is the field perspective. Engineering is developed using direct site experience and in coordination with the teams responsible for installation, connections, testing and commissioning.

The design therefore considers the actual conditions in which it will be built from the outset.

  • Constructability
  • Access and space constraints
  • Cable routes and installation methods
  • Maintainability
  • Interfaces with existing systems
  • Component availability
  • Work sequence
  • Testing and commissioning

Engineering can also be provided as a standalone service. The greatest added value, however, comes when the same technical partner is also responsible for implementation.

Industrial electrical engineering scope

The engineering scope is defined according to the project, plant conditions and documentation already available.

MV/LV power distribution

Primary and secondary distribution architecture, MV/LV transformers, generator sets, feeders and mains, cable routes and auxiliary systems.

A significant part of our work involves integrating new loads and expanding existing operating installations.

Electrical sizing and calculations

  • Load schedules and design currents
  • Cable sizing and current-carrying capacity
  • Voltage drop
  • Short-circuit currents and thermal withstand checks
  • Protection selection and coordination
  • Selectivity and back-up protection where applicable
  • Equipment sizing

Where required, electrical load assessment is coordinated with thermal evaluations and the HVAC system serving the area.

Switchgear and power distribution systems

Engineering of Power Centers, MCCs, distribution switchboards, auxiliary and control panels, DC systems, and integration of new switchgear into existing installations.

Engineering defines architecture, schematics, equipment and documentation; assembly, wiring and testing are covered on our dedicated switchgear page.

LV/MV switchgear →

Revamping and existing-system integration

Site surveys, reconstruction of as-built conditions, review of available documentation, definition of modifications, new layouts and routes, and management of interfaces.

Engineering includes preparation of detailed design documentation and as-built drawings.

Electrical system revamping →

Lighting engineering

Lighting surveys, assessment of existing conditions, studies using dedicated software (DIALux EVO), luminaire selection and layout, and comparison between existing and proposed conditions.

Studies are developed with reference to workplace lighting requirements (EN 12464-1) and have been followed through to implementation.

Electric vehicle charging infrastructure

Definition of supply points, electrical distribution, local switchboards, feeders, protection, earthing and cable routes for separate charging areas within the same site.

One project developed for an industrial site included sizing, single-line diagrams and layouts for a planned total capacity of approximately 219 kW.

Surge and lightning protection

Review of the existing risk assessment and design of the required protection measures, including selection and location of SPDs, in accordance with the EN 62305 series.

The designed measures were implemented and documented through final as-built drawings.

Ancillary supports and installation works

Brackets, supports, cable-support structures, technical platforms and mechanical supports required for equipment and fan installation.

This is not general structural engineering, but the integration of ancillary works required for correct implementation of the electrical system.

How the engineering process is developed

The phases are adapted to the project scope: in some cases the work ends with delivery of engineering documents; in others it continues through plant commissioning.

1

Survey and data collection

Site inspection, plant survey, review of existing documentation, identification of constraints and verification of interfaces with systems remaining in service.

2

Solution definition

Requirements, technical alternatives, integration with existing systems, sizing criteria and selection of electrical architecture.

3

Calculations and design

Sizing, schematics, layouts, routes, technical specifications and component selection.

4

Detailed design documentation

Technical reports, single-line and multi-line diagrams, layouts, plans, cable routes and lists, load schedules, bills of materials, specifications, datasheets and protection settings.

5

Implementation

When included in scope: procurement, assembly, installation, field modifications and coordination of specialist suppliers.

6

Verification and handover

Testing, FAT where applicable, field verification, commissioning, final documentation and as-built drawings.

Engineering applied to real projects

Selected projects where LAMAEL developed the engineering and subsequently delivered the installation.

Engineering and installation of electrical systems for an industrial technology laboratory
Electrical-grid research laboratory

Complete revamping of a technology laboratory

The overhaul of a laboratory housing simulation, measurement and electrical-grid research equipment was approached not as routine maintenance, but as a redesign of the underlying infrastructure.

Based on the as-built assessment and load schedule, a new distribution system, switchboards, power feeders, data and fibre-optic infrastructure were defined, with segregation between power and data routes.

The project also included a technical platform, mechanical supports, fire-rated penetrations, equipotential bonding, thermal-load checks and HVAC compatibility assessment. LAMAEL developed the engineering documentation and executed the works.

Handling of a generator set during installation at a power-generation facility
Power-plant auxiliaries

Integration of new generator sets

Engineering and installation of the electrical infrastructure required to connect two new generator sets serving power-plant auxiliaries, with alternators rated at approximately 1,300 kVA.

Engineering covered load analysis, conductor sizing for currents up to approximately 1,876 A, installation methods for feeders around 100 metres long, voltage drop, short-circuit calculations and protection checks.

The project concluded with connection to the existing busbars, coordinated with the plant operating conditions.

1,600 kVA MV/LV transformer integrated into power-plant auxiliary systems
MV/LV distribution

Integration of an MV/LV transformer into power-plant auxiliaries

Engineering and subsequent installation of the connection for a new 1,600 kVA, 6 kV / 410 V transformer within a power plant’s auxiliary systems.

Feeder sizing defined the number and cross-section of conductors, with overload, voltage-drop, short-circuit and cable-protection checks.

The cable-route layout within the plant was also developed, considering available space and interfaces with existing installations.

DIALux model for lighting design of a power-plant building with control room, changing rooms and offices
Lighting engineering

Relighting of two power-plant control rooms

The lighting upgrade of two control rooms began with a lighting survey and assessment of the existing conditions.

The design, developed in DIALux EVO, assessed illuminance and visual comfort, luminaire selection and layout, comparing existing conditions with the proposed solution.

The required electrical modifications were also engineered and LAMAEL subsequently carried out the work. Our engineering capability extends beyond major power distribution systems.

Additional engineering experience

Projects where engineering was followed by implementation.

Approximately 219 kW electric-vehicle charging installation within an industrial site, with separate charging areas, local switchboards and dedicated earthing.

Lighting and power systems for power-plant buildings and technical rooms, from sizing through installation.

Complete renewal of existing distribution systems with new switchboards, mains, lighting and power systems.

Lightning-protection systems, from review of the existing risk assessment through design, selection and location of SPDs.

Frames and supports required for equipment installation, integrated into the electrical system design.

Special DC electrical systems, including a switchboard rated up to 800 VDC and approximately 240 kW for switching and managing sources used by EV-battery and fuel-cell test benches.

Integrating specialist expertise within the project

For the replacement of two automation and process-control panels within an industrial facility, LAMAEL managed the project scope including surveys, existing-system analysis, intervention definition and coordination, documentation and interface management.

Specialist manufacture of the two panels was assigned to a supplier with the required specific know-how. LAMAEL installed the new systems and carried out field reconnection and integration, maintaining operational coordination and the technical interface with the client.

This is a recurring delivery model: when part of a project requires specialist expertise, the specialist supplier is integrated into the project while LAMAEL maintains coordination and avoids unnecessary fragmentation of client interfaces.

From engineering to commissioning

Depending on the required scope, the service can be limited to engineering or extend through the entire delivery process with one technical point of contact.

For work on existing plants: electrical system revamping, which can itself include engineering, supply, implementation and commissioning.

Technical documentation

The deliverables are defined according to project scope and client requirements; not every document is required for every project.

When implementation is also included, documentation follows the installation through to final as-built drawings.

Engineering is developed in accordance with the standards applicable to each activity, including CEI 64-8 for low-voltage installations, EN IEC 61439 for switchgear assemblies, CEI 0-16 where applicable to grid connection, and CEI 11-27 / EN 50110 for electrical work.
