Details

Etude et travaux pour la fourniture, le montage, la mise en service d'un dispositif de prévention de mélanges incompatibles sur l'aire de dépotage de chlorure ferrique de l'usine de Seine Grésillons. Il remplacera l'installation de dépotage existante qui devra être démantelée. Le dispositif sera installé dans une loge existante. Les travaux comprennent le raccordement des réseaux (électrique, informatique industrielle, hydraulique, génie civil, etc..) sur les installations existantes de l'usine. Les dispositifs de prévention des mélanges incompatibles visent à autoriser et permettre le dépotage du produit, et uniquement du produit, dans sa zone de dépotage dédiée. Le système interdit et prévient tout dépotage d'un produit différent. L''opération consiste en la réalisation d'un test sur le chlorure ferrique, qui est un produit opaque pour lequel le SIAAP n'a pas de référence

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.
