Reason for Change Order:
• During construction and boring under Hammond Avenue,multiple large boulders prevented the work to continue. Means
and methods were changed by the Contractor to complete the task.
• During Construction at Alexandria Drive, it was found that an external drop pipe increase from 8"to 12"and 36"storm
sewer(previously unknown)crossing was necessary.
• To accommodate the provided acoustical enclosure for the Texas Street generator,the pad size needed to be increased.
• During installation of the service connection to the existing electrical system at Texas Street,MidAmerican stopped work
so that the existing transformer could be evaluated. It was determined that MidAmerican needed to upgrade the
transformer at the site to meet current system specifications. This required a new transformer pad and new electrical
wiring and conduits.
