Description

Ingénieur Géomètre Topographe Freelance avec plus de 15 ans d'expérience (SNCF, RATP, BTP), je vous propose mes services pour vos projets d'infrastructures complexes. Équipé de mon propre matériel (GPS, Station Totale, Scanner 3D), j'assure une synergie totale entre relevés terrain et ingénierie de bureau d'études.

Expertise Ferroviaire : Les 4 Casquettes

Mon profil se distingue par une maîtrise complète de la chaîne technique ferroviaire :

Topographie & Métrologie : Levés de haute précision, établissement de canevas, relevés de voies (exploitation/travaux) et fiches de contrôle pour la sécurité des circulations.

Études de Tracé : Conception et vérification géométrique (alignements, courbes, paraboles, dévers) selon les référentiels SNCF, RATP et Arema.

Études d'Armement : Expertise sur les constituants de voie (rails, traverses, ballast) et implantation critique des Appareils de Voie (ADV).

Études de Gabarit : Analyse des zones de dégagement (tunnels, gares, obstacles) par nuages de points 3D pour garantir l'engagement du matériel roulant.

Maîtrise Logicielle & BIM

Expert des outils métiers, je garantis des livrables conformes aux exigences numériques actuelles :

Ferroviaire : Bentley Power Rail Track, Géorail, Tipule, Epure.

CAO/VRD : AutoCAD, Civil 3D, Covadis, Autopiste.

BIM : Création de jumeaux numériques (Digital Twins) à partir de scans 3D.

Pourquoi collaborer avec moi ?

Réactivité : Basé en Île-de-France, mobile en ile de France

Fiabilité : En gérant la mesure et l'étude, je supprime les erreurs d'interface.

Polyvalence : Auscultation d'ouvrages, implantations de précision et calculs de cubatures.

Je suis prêt à mobiliser mon savoir-faire pour la réussite de vos missions. Contactez-moi pour un entretien technique.

Permanent Contract Railway Design Engineer - Gauge
TRANSPORTATION
May 2024 - January 2025 (8 months)
Paris, France
Company Description:
RATP (Régie Autonome des Transports Parisiens) is a French public transport operator founded in 1949. It operates the metro, RER, buses, and trams in the Île-de-France region, transporting millions of passengers daily.

Context:

Tasks Performed
- Ensured system gauge studies for various rolling stock (MI20, MF19, etc.).
- Provided progressive training to a colleague on gauge, mass, and clearance calculations.
- Developed advisory sheets (VISA) on documents provided by rolling stock manufacturers (Alstom, Bombardier, CAF).
- Performed dynamic gauge, manufacturer gauge, and workshop gauge calculations.
- Conducted studies related to the design and construction of bogies.
- Carried out studies on the gauges required for RFID chip installation.
- Participated in tenders, including providing opinions on coupling gauges and attending meetings with bidders to discuss proposals and specific requirements.
- Performed mass studies on the axles and wheels of rolling stock (MR).
- Analyzed the dynamic gauge of the MI20 rolling stock (RER) on Line A.
