Details

Ordonnancement, Pilotage et Coordination Interchantiers (OPCI) pour le réaménagement du pôle gare porté par la CASGBS et du projet de Désaturation de la gare de Sartrouville porté par SNCF Gares & Connexions

Le contrat comporte des tranches optionnelles définies au cahier des charges. Le détail des missions confiées au titulaire figure au cahier des charges. Les prestations sont réglées par des prix forfaitaires. Cette mission s'inscrit dans un contexte particulier marqué par la concomitance de deux opérations majeures conduites par deux maîtres d'ouvrage distincts : - L'opération de réaménagement du pôle gare portée par la CASGBS ; - L'opération de désaturation du bâtiment voyageurs de la gare de Sartrouville portée par SNCF Gares & Connexions. Ces deux opérations présentent des calendriers de réalisation convergents, des emprises géographiquement imbriquées et de nombreuses interfaces techniques, fonctionnelles et organisationnelles. Elles seront réalisées dans un environnement fortement contraint, caractérisé par le maintien de l'exploitation ferroviaire, de la gare routière et des circulations des usagers pendant toute la durée des travaux. Dans ce contexte, la mission confiée au titulaire consiste à assurer la coordination des interfaces entre les deux opérations afin de garantir leur compatibilité technique, organisationnelle et temporelle, tout en permettant à chaque maître d'ouvrage de conduire son projet dans le respect de ses propres objectifs, contraintes et responsabilités

Documents

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this construction & infrastructure opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
