Emergency Sinkhole Investigation and Repair

The U.S. Embassy Brussels requires a firm-fixed-price contract for the immediate investigation and repair of a sinkhole located on Rue Zinner within the Embassy compound. The objective is to determine the source of the sinkhole and restore the street to its original cobblestone design, reopening it to traffic. Required tasks include sinkhole investigation utilizing diagnostic tools, street stability analysis with ground penetrating radar, excavation, repair of the source, and backfilling/surface repair. Contractors must adhere to all applicable safety requirements related to excavation, heavy machinery, and confined spaces. A street stability analysis and photos of the sinkhole source are required deliverables. Crucially, the government must be immediately informed if excavation exceeds five meters in depth due to proximity to adjacent building foundations. All contractors must be registered in SAM.gov prior to submitting an offer, and electronic submissions (Adobe Acrobat - PDF, under 30MB, or split into <2MB emails) are required to BrusselsBids@state.gov by December 10, 2025.
