Fisk, E.I.T. - Associate Engineer Date: September 22, 2016 Re: Change Order Number 7 for the Primary Clarifier Project This memo has been provided as supporting documentation for change order number 7 for the primary clarifier project. This change order is for a total of $2,715.00, including tax. This change order is to provide exterior door mounts on the LCP 250/251. This work is necessary in order to facilitate quick access by the treatment plant operators; in particular for access to the emergency stops. Without having these devices mounted on an exterior door, there is only one operator at the treatment plant that would be able to open the panel due to arc flash rating. Steve Brewer and Dan Ford approved the change order on September 22. Please sign the attached change order. If you have any questions or any additional information is needed, please let me know.

Fisk, E.I.T. - Associate Engineer Date: September 28, 2016 Re: Change Order Number 8 for the Primary Clarifier Project "EMITIrl This memo has been provided as supporting documentation for change order number 8 for the primary clarifier projea This change order is for a total of $66,645.43, including tax. This change order also includes the addition of 17 working days to the contract. Below is a summary of the change order: Digester Drain Piping - $41,976.27 with the addition of 12 days to the contract With the design, there was no way to drain the digester if it overflowed when only the new clarifiers were operating. HDR claims this was missed during the design due to a misunderstanding of how they believed the digester overflow pipe discharged. This change order adds an 8 -inch DI pipe to each new clarifier, valving, a cleanout, and a connection to the non -potable water system to prevent freezing of the drain lines in the winter. This change order was done as a force account which reduced the amount from $45,000 before tax to a cost of $41,976.27 Non -Potable Water Revisions — a credit to the City of $4,200 In order to isolate the spray bars, the non -potable water system design needed to be modified, which involved adding several valves. Due to space constraints, the required drywells were eliminated and the system was instead connected to the scum pump station to drain. Piping materials were changed from 4 -inch cement - lined ductile iron to 4 -inch PVC, providing a cost savings to the City. • Water_stop in Sludge Pumping Room and Headworks - $3,133.50 A waterstop was not shown in the plans for locations where the Contractor was required to connect new structures to existing structures, such as the headworks and the sludge pumping room. This was added in order to seal the joints. • Re-route Non -Potable Water Line around Pumping Room - $960.42 with the addition of 1 day to the contract In order to protect electrical items and meet code, the non -potable water line in the sludge pumping room was re-routed to the exterior of the room. This reduced the total length of pipe and eliminated some fittings such as pipe supports and a hose rack. The Contractor also found a non -potable water line outside which needed to be replaced, which added about 70 linear feet of piping and four valves which were not in the Contract.
