This technical memorandum serves as a summary of the Proposal Evaluation conducted in support of the On-Site Hypochlorite Generation (OSHG) System Procurement Project by the City of Burnsville, MN (City). Due to differences in equipment layout, operation, electrical and heat loads, and construction, the decision was made to procure an OSHG system supplier (OSHGSS) prior to design of the Chlorine Rehabilitation Project. Proposals were solicited from the three pre-qualified OSHG vendors – Process Solutions Inc – Microclor® (PSI), Parkson Miox (Miox), and Severn-Trent Chlor-Tec (Chlor-Tec). This memorandum outlines the submittal evaluation process and results of the evaluation.
1.2 Comparative Evaluation Summary
A Proposal Evaluation Tem, comprised of WTP Staff and City Engineers, utilized a comparative evaluation process to evaluate proposals for the On-Site Generation Equipment Procurement Contract and establish the best value for the City.
