Niveau :

SPB2 / SPB3 (Selon expérience)

Localisation :

Directement basé sur site de grand projet (ex : HPC, SZC au Royaume-Uni, ou Belfort avec détachements longs sur chantier)

Déplacements :

Mobilité locale et sur chantiers de construction (environ 50% à 60% du temps sur le terrain)

Rattachement :

Hiérarchique: Direction OPEX

Fonctionnel : Direction C&C

Résumé du poste

Le Responsable Lean Construction & Performance Chantier est le garant de l'efficacité opérationnelle et de la productivité directement sur les zones de construction, de montage et d'installation des équipements lourds (notamment l'îlot turbine et les systèmes associés).

Il/Elle travaille au plus près des équipes d'exécution (superviseurs, chefs de chantier, compagnons et sous-traitants) pour fluidifier les flux de matériel, optimiser l'enchaînement des tâches de montage, minimiser les temps morts (attentes, manutentions inutiles) et garantir le respect du planning directeur dans un cadre réglementaire et de sécurité extrêmement strict.

Description du poste

Responsabilités Essentielles

1. Optimisation de la Planification Collaborative (Last Planner System) : Structurer et animer la planification à court terme (6 semaines / 3 semaines / quotidienne) directement avec les conducteurs de travaux et les sous-traitants pour identifier et lever les blocages opérationnels avant qu’ils n’impactent le chantier.

2. Gestion de la Coactivité & Logistique Chantier (Kitting & Flux) : Optimiser l'approvisionnement des composants sur le point d'utilisation (juste-à-temps, préparation de kits de montage, standardisation du stockage intermédiaire) afin de maximiser le temps de travail productif des monteurs.

3. Résolution des Écarts et Amélioration Continue (Gemba Focus) : Analyser quotidiennement les causes de non-productivité sur le chantier (retards de livraison, outils manquants, problèmes de qualité, coactivité mal gérée) et piloter des plans d'action correctifs immédiats avec les équipes travaux.

4. Standardisation et Rituels de Performance : Mettre en place et animer des rituels de performance terrain (points 5 minutes de démarrage, gestion visuelle de l'avancement physique de l'installation, indicateurs de performance clés par zone).

5. Animation de la Sûreté et de la Propreté (5S / FME) : Déployer les standards 5S adaptés aux contraintes nucléaires sur le chantier, notamment pour la prévention de l'introduction de corps étrangers (FME - Foreign Material Exclusion) et le maintien de zones de travail sécurisées.

6. Accompagnement au Changement : Former et coacher les équipes de supervision de chantier et les partenaires extérieurs aux concepts fondamentaux de la Lean Construction.

Qualifications requises

· Formation : Diplôme d'Ingénieur en Génie Civil, Génie Industriel, Mécanique ou Gestion de Projet de Construction.

· Expérience Terrain : Minimum de 10 ans d'expérience dans la gestion ou la supervision de grands chantiers de construction lourde (centrales énergétiques, pétrochimie, infrastructures ferroviaires ou navales).

· Expertise Lean Construction : Maîtrise éprouvée des outils spécifiques au secteur (Last Planner System, Takt Time Planning, Management Visuel de chantier, VSM de flux logistiques).

· Culture Sûreté Nucléaire : Connaissance solide des exigences applicables sur un chantier de construction nucléaire (standards d'assurance qualité, traçabilité rigoureuse, culture de sécurité "Zéro Accident").

· Langues : Anglais et Français courants (capacité à animer des réunions de chantier et à rédiger des procédures de travail dans les deux langues).

Caractéristiques souhaitées

· Crédibilité Technique et Relationnelle : Capacité à dialoguer d'égal à égal avec un chef de chantier ou un directeur de projet grâce à une solide culture technique de la construction.

· Pragmatisme et Terrain : Forte appétence pour l'action directe sur le terrain ("bottes aux pieds") plutôt que pour le travail exclusif de bureau.

· Excellente Communication : Capacité à fédérer des équipes issues d'entreprises sous-traitantes et de cultures différentes autour d'un objectif de performance commun.

· Esprit d'Analyse Rapide : Réactivité face aux imprévus climatiques, techniques ou logistiques pour réorganiser les tâches de manière optimale.

Level:

SPB2 / SPB3 (Depending on experience)

Location:

Directly based on a major project site (e.g., HPC, SZC in the UK, or Belfort with long-term site deployments)

Travel:

Local mobility and construction sites (approx. 50% to 60% of time in the field)

Reporting Line:

Line Manager: OPEX Department

Functional Manager: C&C Department (Construction & Commissioning)

Job Summary

The Lean Construction & Performance Site Manager is the guarantor of operational efficiency and productivity directly on the construction, assembly, and heavy equipment installation areas (particularly the turbine island and associated systems).

He/She works as close as possible to the execution teams (supervisors, site managers, craft workers, and subcontractors) to streamline material flows, optimize the sequencing of installation tasks, minimize downtime (waiting, unnecessary handling), and ensure compliance with the master schedule within an extremely strict regulatory and safety framework.

Job Description

Core Responsibilities

  • Collaborative Planning Optimization (Last Planner System): Structure and facilitate short-term planning (6-week / 3-week look-ahead / daily) directly with site managers and subcontractors to identify and remove operational roadblocks before they impact the construction path.
  • Coactivity & Site Logistics Management (Kitting & Flows): Optimize component supply to the point of use (just-in-time, installation kit preparation, intermediate storage standardization) to maximize productive working time for installers and mechanical fitters.
  • Deviation Resolution & Continuous Improvement (Gemba Focus): Analyze daily causes of non-productivity on site (delivery delays, missing tools, quality issues, poorly managed coactivity) and drive immediate corrective action plans with construction teams.
  • Standardization & Performance Rhythms: Set up and run field performance rituals (5-minute morning huddles, visual management of physical installation progress, key performance indicators per zone).
  • Safety and Cleanliness Drive (5S / FME): Deploy 5S standards adapted to nuclear constraints on site, particularly for Foreign Material Exclusion (FME) prevention and maintaining clean, safe work areas.
  • Change Management: Train and coach site supervision teams and external partners on the fundamental concepts and tools of Lean Construction.

Required Qualifications

  • Education: Engineering degree in Civil, Industrial, Mechanical Engineering, or Construction Project Management.
  • Field Experience: Minimum of 10 years of experience in managing or supervising large-scale heavy construction sites (power plants, petrochemicals, rail or naval infrastructure).
  • Lean Construction Expertise: Proven mastery of sector-specific tools (Last Planner System, Takt Time Planning, Visual Management of construction sites, logistical flow VSM).
  • Nuclear Safety Culture: Strong knowledge of applicable requirements on a nuclear construction site (quality assurance standards, rigorous traceability, "Zero Accident" safety culture).
  • Languages: Fluent English and French (ability to run site meetings and write work procedures in both languages).

Desired Characteristics

  • Technical and Relational Credibility: Ability to engage on equal terms with a site manager or a project director thanks to a solid technical construction background.
  • Pragmatism and Field Focus: Strong appetite for direct action in the field ("boots on the ground") rather than exclusive office work.
  • Excellent Communication: Ability to unite teams from subcontracting companies and different cultures around a common performance goal.
  • Rapid Analytical Mindset: High responsiveness to weather, technical, or logistical contingencies to reorganize tasks optimally.
