NIGP 49570: Oceanography and Limnology Equipment: Dredges, Thermographs, etc.

NIGP 49570 Oceanography and Limnology Equipment: Dredges, Thermographs, Etc., Item code, encompasses both specialized water-quality monitoring instrumentation and coastal maintenance dredging services as currently solicited by state and local governments. Recent activity shows two distinct procurement streams: portable multi-parameter sondes and related sensors for real-time water-quality data collection, and large-scale hydraulic dredging operations for inlet and waterway maintenance. The issuing bodies are primarily coastal counties and special-purpose districts managing environmental monitoring and waterway infrastructure, with Collier County, Florida emerging as a repeat buyer for grant-funded dredging projects.

Collier County, Florida dominates recent activity with two overlapping sealed competitive bids for the Wiggins Pass and Doctors Pass Maintenance Dredging Project 2026 (Bid No. 26-8661 and 26-8661R), both grant-funded initiatives requiring removal of approximately 115,000 to 122,600 cubic yards of sand from coastal inlets with anticipated project budgets of $2,800,000. The earlier iteration closed March 30, 2026; a revised bid closed May 22, 2026, requiring substantial completion within 90 calendar days and final completion within 120 days, with liquidated damages of $2,667 per calendar day for delay. Bidders must demonstrate three to five prior hydraulic dredging projects in open water, deploy a minimum 14-inch hydraulic dredge capable of 6,000-foot pumping distance, and maintain pollution liability of $1,000,000 per occurrence. The projects apply local vendor preference and federal prevailing wage standards but do not specify minority or disadvantaged enterprise set-asides. Separately, Okaloosa County Tourist Development Council issued RFQ REQ26000532 on June 2, 2026, for a portable multi-parameter sonde system measuring temperature, conductivity, pH, dissolved oxygen, and depth in natural waters with mobile app control and June 15, 2026, delivery required; quotes must include calibration solutions and hard-sided protective case with stock-on-hand confirmation and no refurbished equipment accepted.
