Details

Het project Boonstraat in Oegstgeest markeert een cruciale stap in het verbeteren van de waterhuishouding en het optimaliseren van de leefomgeving. Centraal staat de aanleg van een duikerconstructie die niet alleen functioneert als regenwaterriool (vanaf hier aangeduid met “HWA/ duikerriool”), maar ook bijdraagt aan een robuuste beheersing van het polderpeil in de Oudenhofpolder.

Dit multidisciplinaire project integreert rioleringswerkzaamheden met verbeteringen aan groen- en weginfrastructuur, waardoor een efficiënte en samenhangende aanpak wordt gerealiseerd. Het project is een direct gevolg van het verbeterde waterafvoerstructuurplan dat in 2015 door de gemeente Oegstgeest en het Hoogheemraadschap van Rijnland is overeengekomen

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.
