Title
Approving a change order in the amount of $219,737 and 441 additional days for the Emergency Standby Generator Project, and authorizing the City Manager to execute the same.
Summary
As has been noted on other previous City Council items, there is a significant delay in electrical components including electrical switchgear and transformers. At the time of bidding the standby generator project, the longest lead time item was the generator itself which had a lead time of roughly 50 weeks. While the generator itself has been delayed some due to the global market, we have started to experience delays in other critical infrastructure as part of the project. Some of the critical equipment includes the primary transformers for the project. As these items weren't seeing abnormal lead times when this project bid, it was not determined at that time that a pre-procurement of them was necessary. Although the contractor was able to have submittal approved in a timely manner and the transformers were ordered in early spring 2022, they are now not going to be delivered until late 2023. This change order would facilitate providing additional days to the contractor for the delay in manufacturing the transformers that is outside of the City's or the contractor's control.
This change order will also address items that were not originally identified during the design process. Those items are:
1. More optimized construction sequencing by altering the generator layout that reduces risk to the City while the generators are being installed. This sequencing calls for a rotation of the generator 90 degrees which prevents the City from having extended periods of power loss during the installation, but requires an extra length of cable to hook the generators to the new switchgear. This cost is $90,427.49 of the change order not including bonding.
2. Relocation of an existing 12" water line that was improperly located on the as-built drawings for the facility. The line ...
