Environmental site assessment

The U.S. Embassy in Bogota, through the General Services Office and under the oversight of the Department of State’s Overseas Buildings Operations, is seeking qualified vendors to perform a Phase I Environmental Site Assessment (ESA) for three sites in Bogota, Colombia, which are intended for transfer to the City of Bogota as public parks. The requirement, issued as a Request for Quotation with solicitation number PR16010664 and NAICS code 541360, mandates a comprehensive assessment in accordance with ASTM Standard E1527-05, including historical review of site ownership and usage, identification of potential contaminants, verification of underground utilities, and compliance with local environmental regulations and building codes. Offerors must submit a technical proposal detailing site investigation phases, laboratory testing protocols, and a schedule outlining key milestones in days—from notice to proceed through commencement and completion of site visits to final report delivery. The technical proposal must also include warranty terms and evidence of relevant experience over the past two years, with client names, contract values, and points of contact provided. Proposals must be submitted via email to bogotagsocompras@state.gov by June 5, 2026, at 4:00 PM Bogota time, with PR16010664 clearly stated in the subject line. Cost proposals must itemize unit prices, tax percentages, tax amounts, and total amounts separately for each site and service category, with pricing for Colombian vendors required in Colombian Pesos (COP). All offers must remain valid for six months and be accompanied by two years of financial statements demonstrating sufficient resources to fulfill the contract. Mandatory certifications include compliance with the National Defense Authorization Act (NDAA) Section 889 regarding prohibited telecommunications and surveillance equipment, as well as a signed affirmation that the offeror fully understands and accepts the requirements. Evaluation will be based on technical compliance and financial capability as pass/fail gates, followed by assessment of the technical proposal, cost proposal, and schedule. Draft ESA reports must be submitted in English within 45 days of notice to proceed, with final reports delivered within five days after OBO review comments are addressed. Payment will be made via EFT within 30 calendar days after receipt and acceptance of deliverables, and all work is to be performed at DDP delivery to the Embassy warehouse in Bogota.
