Body
Dear Sir:
On January 18, 2024, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 23-119-12 Taxonomic Algal Assessment of the Upper North Shore Channel to EcoAnalysts, Inc., in an amount not to exceed $26,168.00. This contract is scheduled to expire on December 31, 2025.
This contract has no prior change orders.
Original Purchase Order Amount $26,168.00
Date of Board Approval 1/18/2024
Cumulative Change Order (4/4/2025) $0.00
% Change of Original Purchase Order Value 0.00%
Current Contract Value $26,168.00

New Purchase Order Value $41,368.00
% Change of Current Purchase Order Value 58.09%
% Change of Original Purchase Order Value 58.09%
An increase is requested to support the analysis of additional samples for the algal assessment of the Upper North Shore Channel (UNSC). While the first year of sampling provided novel data, the results indicated the need for additional sampling events to more effectively capture seasonal variations and site-specific trends in phytoplankton and zooplankton population dynamics in this section of the waterway. The proposed increase will fund sixteen (16) additional sampling events, including four (4) focused on upstream and downstream control sites. This expanded effort will provide a more comprehensive understanding of which algal species thrive under winter conditions and the environmental stressors that may influence their growth. Ultimately, the findings will help identify the mechanisms driving these blooms.
This change order complies with the Illinois Criminal Code, as the need for additional sampling was not reasonably foreseeable at the time of contract execution, and the increase serves the best interests of the District.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute a change order to increase the purchase order for Contract 23-119-12 in an amount of $15,200.00 (58.09% of the current contract value), from an amount of $26,168.00, to an amount not to exceed $41,368.00.
Funds are available in Account 101-16000-612490.
Requested, Edward W. Podczerwinski, Director of Monitoring and Research, EWP:RA:HZ:JV:jb
