Larrie Tchag · Project lead · South Paris region
Since 2018, I have worked on major industrial and commercial projects.
My varied background is a strong technical asset in managing complex projects and lets me size an installation as a whole.
My skills cover cost estimating and priced bills of quantities (DPGF), tendering and negotiation, leading design teams, site crews and subcontractors, and coordinating the technical interfaces between BIM, design teams, clients, architects and programme coordination, through to snagging, fire safety inspections and the as-built file (DOE).
Design · Installation · Repair · Maintenance
Sectors
My experience, from site work to the design office, lets me approach electrical projects as a whole, balancing design requirements, construction constraints and the coordination of interfaces between clients, design teams and contractors.
From survey to as-built file
From low-voltage power installations to communication, security and automation systems, I work on the design, sizing and technical coordination of installations, taking in regulatory requirements, operating constraints and the interfaces between trades.

Company and project context
Fouassin — Groupe Myrium
Morangis (91)
General electrical contractor founded in 1921 and part of the Myrium group since 2013, working on power and low-current systems, mainly in the commercial sector.
Part of a consortium with Rougnon (Myrium group) and Dalkia for the elevated stations and emergency exits of line 18, Fouassin gradually took on a larger scope than planned. A dedicated organisation had to be set up quickly to produce and manage the construction-stage design, under the project director.
This led to a phase of operational structuring while production was under way.
2023 – 2026
Managing and producing construction-stage design and BIM, lighting and LV distribution packages
Companies and project context
Initially working with a subcontractor that wanted to expand into design and engineering, I worked with the IngéBIME and ATOMI design consultancies as electrical design project lead (LV power and low-current).
These collaborations aimed to answer multi-trade MEP tenders (HVAC / electrical / plumbing) for new-build, refurbishment and renovation projects.
The same collaboration also led me to work directly with NovArchi, an architecture practice, on diagnostic studies ahead of electrical refurbishment and renovation projects.

Company and project context
SLTE — Société Landaise de Travaux Électriques
A group of SMEs from the Landes region, working on electrical projects across France.
SLTE was selected for the construction of the Roseraie no. 5 hospital in Aubervilliers (93), largely thanks to its experience on the earlier Roseraie no. 4 projects and the trust built with the site operator.
Given the size and complexity of this new project, the company had to strengthen its local team by recruiting people experienced in running and managing major projects.
I joined in this context, to take charge of the technical and operational work outside the company's usual scope.
First brought in to support works management, my scope gradually widened to project management and then to managing the construction design.
This led me to take operational responsibility for the low-current (CFA) packages, delegated by the senior project manager, coordinating the design, the installation crews and the project's technical interfaces.
2021 – 2023
Managing construction design and operational lead for the low-current packages — Coordination of power and low-current design and works
Company and project context
SBE — Spie Batignolles Énergie · Service Proximités
Subsidiary of the Spie batignolles group specialising in electrical engineering.
Originally focused on one-off interventions and small call-off jobs, the Service Proximités team wanted to move into mid-sized projects, in particular jobs under €1M.
The works manager in place, already taken up by delays and difficulties on a previous site, no longer had the time to fully coordinate this new project.
I was brought in to take over operational management of the site: coordinating crews and works, tracking procurement, technical installations, complex light structures and commissioning.
The priority was to keep progress under control so as not to jeopardise the planned fire safety inspection date.
2020 – 2021
Operational management of power, low-current and fire safety works — Technical coordination, team leadership and commissioning
Company and project context
Eiffage Énergie Systèmes · Service Grands Projets
Designs, builds, operates and maintains electrical, industrial, HVAC and energy installations for industry, infrastructure, cities and the commercial sector.
For the new Robert Schuman convention centre, Eiffage Construction led a design-build-maintain consortium, with Eiffage Énergie in charge of the technical packages. Designed by Wilmotte & Associés, the 15,300 m² building includes a 1,200-seat auditorium, 16 committee rooms and exhibition spaces.
I was first brought in for a short-term need: the project manager was looking for two electricians experienced in electrical cast-in works in foundations, certified for work at height (CACES 3B).
Difficulties in mobilising the staff planned by the consortium companies gradually changed how the site was organised.
My responsibilities then grew beyond the initial assignment: from electrical installation to leading crews, and then to managing the works.
2016 – 2018
First major project in management — From electrical installation to site leadership and works management for power, low-current and fire safety
2005 – 2017
Installation, commissioning, maintenance and repair of power and low-current systems
From 2005 to 2017 I worked as an electrician on a wide range of temporary assignments, mainly in the Metz area.
These assignments took me into many kinds of electrical installations: public buildings (ERP), workplaces (ERT), industrial sites, factories and hospitals.
I worked on new builds, refurbishments, industrial maintenance and plant shutdowns, from cast-in works in foundations through to terminations and commissioning.
This variety of assignments gave me hands-on knowledge of electrical equipment, how it is installed and the constraints of on-site work.
It is now the foundation of my technical approach to design and project management, linking solutions drawn on paper to the realities of building them on site.
I structure the technical and document production of projects, from organising the design work through to the as-built file (DOE).

From electrician to project lead, my path was built on site, through learning, adapting and taking on responsibility.
After training in electrical engineering, I worked for more than ten years as an electrician on varied assignments in buildings, offices, industry and hospitals.
In 2016, joining major projects was a turning point. First brought in for my technical skills, I gradually moved on to leading crews, managing works and coordinating operations.
This then led me to construction design, design engineering and project management, both with contractors and with design consultancies.
Alongside this, I develop my own working methods, calculation tools and document organisation systems to structure and ease technical production.
Today, my experience lets me approach electrical installations as a whole, combining design requirements, construction constraints and the coordination of everyone involved.
