"EPE did a great job assuring that all commissioning requirements were met for this very challenging project.  I am very pleased with the outcome of the commissioning process managed by EPE.  Jimmy Jen is an excellent commissioning agent and was able to conduct the commissioning process within some very challenging circumstances.

EPE exceeded the City's expectations and was able to complete all technical aspects of the commissioning process while also managing good relationships with all parties, all within greatly extended timelines and delays.


The commissioning process is still somewhat new in the world of construction so there is considerable push-back from sub-contractors in their attempts to avoid their somewhat new responsibilities.  Jimmy was able to maintain excellent relationships with sub-contractors by being firm but fair in his approach to enforcing the contract requirements behind commissioning.  In addition, he was flexible and helpful when challenges emerged and things had to be done in a way that diverged from the original plan.  I would recommend EPE and Jimmy Jen to act as commissioning agent on other public building projects.


Thank you for all your hard work and perseverance on the Emergency Coordination Center.  I hope we have a chance to work together again in the future."
