This amendment to Solicitation No. 140P5426Q0005 provides crucial clarifications regarding culvert cleaning and inspection within the Flamingo District, an environmentally sensitive area. Key points include strict environmental restrictions, such as no equipment in wetlands and a mandatory biological monitor daily. The scope involves culvert barrel cleaning and inspection, with a 15-foot clearing radius around inlets/outlets, but no tree removal. Contractors must supply their own water, dispose of all collected debris and wastewater off-site, and provide disposal receipts. Full CCTV inspections are required even if culverts are submerged, along with comprehensive DOT inspections and elevation data. Work must occur during the dry season (December-February), and no weekend work is permitted. All culverts are considered environmentally sensitive due to protected species, including American crocodiles.

The National Park Service – Contracting Operation East – South MABO is soliciting quotes for culvert cleaning and inspection services in the Flamingo District of Everglades National Park.

Key dates include a site visit on March 19, 2026, questions due by March 25, 2026, and quotes due by April 3, 2026. Evaluation criteria prioritize price, technical ability, completion time, and past performance. Offerors must have a valid Unique Entity ID (UEI) and an active SAM.gov registration, self-certifying under NAICS Code 238990. Submissions must include a completed SF18, a formal company quote, a technical approach, past performance references, and completion of FAR 52.204-24 related to telecommunications equipment. Payments will be processed electronically via the Invoice Processing Platform (IPP).

The National Park Service (NPS) Transmittal Form (CM-16Rev. 4/00) is a standardized document for managing project submittals, such as those for Everglades National Park. It facilitates communication and approval processes between contractors, subcontractors, suppliers, and the NPS. The form requires detailed descriptions of submitted items, their specifications, and the number of copies. NPS actions include approving, approving with notes, or disapproving with a resubmission requirement. The form also includes certifications of compliance with contract requirements (FAR 52.236-21) by the contractor and review comments from the Contracting Officer’s Representative. This transmittal emphasizes that government approval is for general concurrence and does not transfer responsibility for errors or omissions. The document outlines a submittal log with specific dates for tracking the review process and details distribution channels for various stakeholders.

Attachment C: Everglades National Park Compliance Division outlines essential conservation measures for culvert cleaning operations within Everglades National Park, focusing on protecting listed species. These measures include stopping work when animals like the Cape Sable seaside sparrow, Eastern black rail, wood stork, Florida bonneted bat, Florida panther, American crocodile, and Eastern indigo snake are present. Restrictions are in place for work during breeding seasons, particularly for sparrows, rails, and crocodiles. The document mandates reporting all animal encounters to the EVER Biological Resources Branch. A biological monitor is required on-site throughout the project to survey for sensitive species, enforce conservation measures, and coordinate with the EVER Biological Resources Branch for guidance on listed species. Additional conservation measures cover vegetation removal, tree trimming (with strict guidelines for mangrove and large tree removal), interior culvert cleaning (prohibiting ground disturbance and ensuring proper disposal of spoil material), and the use of specific equipment to prevent environmental discharge. All personnel must be briefed on T&E species, and equipment must be cleaned to prevent the spread of invasive species. The overall purpose is to minimize environmental impact and protect sensitive wildlife during necessary infrastructure maintenance.

This Statement of Work (SOW) outlines the requirements for cleaning and inspecting 117 culverts in the Flamingo District of Everglades National Park. The project aims to restore hydraulic performance and structural integrity by removing sediment, vegetation, and debris. Following cleaning, each culvert will undergo camera inspection to document its condition, identify deficiencies, and generate a comprehensive report with photos, quantity takeoffs, cost estimates for repairs, and GPS coordinates. The contractor is responsible for providing all labor, materials, tools, and equipment, as well as off-site disposal of debris. Special responsibilities include protecting existing infrastructure, adhering to environmental compliance, and identifying and avoiding threatened and endangered species. The work must be completed within 90 days of the notice to proceed, during normal business hours, between October 1, 2026, and March 1, 2027. The contractor must submit a Hazard Analysis & Safety Plan, daily performance reports, and various post-award documents. The government will conduct periodic and final inspections, with final payment contingent upon satisfactory correction of any deficiencies.

The document, produced by the National Park Service South Florida Natural Resources/GIS Division in September 2023, is a map detailing culvert locations along Main Park Road, Mahogany Hammock Road, and Old Ingraham Highway within Everglades National Park. It specifically focuses on the Flamingo Main Park Road Culvert Locations. Data sources for the map include NPS and ESRI basemaps. An important update notes the addition of an

The document lists 116 culverts, primarily cross-drainage, reinforced concrete, located along FLMR RTE 010 Flamingo Route 10. One culvert is galvanized steel and is located on FLVC Guy Bradley Trail, which is a parent of FLMR 010 Culverts. The reinforced concrete culverts vary in length from 36.0 FT to 58.0 FT, with a diameter of 24.0 IN, except for one that is 18.0 IN. The single galvanized steel culvert is 14 FT long and 12 IN in diameter. This detailed inventory suggests a procurement or maintenance project for drainage infrastructure along the Flamingo Route 10 and related areas.
