GOC325840-CS-2 - Optimize Cooling Plant for Energy Performance

Statement of Work/Overview:
Optimize the cooling plan for energy performance. This project encompasses the replacement of the   two (2) chillers and installation of VFDs on the three (3) primary chilled water pumps (P-8, P-9 & P-10) and the back-up secondary chilled water pump (P-12) and to revise and implement additional controls to optimize the chiller plant. The control valves on the main air handling equipment (i.e. VAV AHU, Office MUA unit and six (6) compartmental units) will not be modified. The sequence of operation for the chillers, primary and secondary chilled water pumps and cooling towers will be revised and/or added in the BAS so that all equipment runs within its optimum efficiency range and to have equal run-times for all of the equipment. This will ensure that the cooling plant operates at peak performance and extends the service life of the equipment. In addition, since standard-duty motors cannot operate reliably at lower RPMs, the existing three (3) primary and two (2) secondary chilled water pump motors will be replaced with new inverter-duty motors. Consultant to investigate heat recovery options for using waste chiller heat in the buildings domestic hot water and or perimeter heating system. 
                                                                                                                                                                      Respondents must have successful previous experience in maximizing chiller plant performance for energy savings. In order to demonstrate this previous experience, Respondents shall provide three (3) separate and independent reference from projects, similar in scope and complexity that are within the past 10 years, in which the business owners indicate that they would rehire the Consultant for future work.  Projects submitted will be evaluated on the project write ups provided below by the Respondent. A YES or NO answer to the following items below without substantiation may deem a Quotation   non-compliant and not considered for award.
Please describe/demonstrate in detail for each of the three (3) projects the points indicated below. Use additional pages if necessary.
 ALL REFERENCE PROJECTS SHALL CLEARLY DEMONSTRATE THE FOLLOWING:
1. Successful use of load calculations to correctly size equipment used.
2. Successful optimization of BAS and Sequence of Operations.
3. Successful experience in replacing chillers for energy savings not just lifecycle requirements.
4. Successful incentive collection.
 
If respondent does not meet the experience requirements stated in this RFQ, this may, in Brookfield GIS' sole discretion, cause the Quotation to be considered non-compliant and not considered for award.
