Catalina Subdivision Water Main and Storm Sewer Replacement Additional Oversight – Change Order Request #4
History
Catalina Subdivision Phase I-III Engineering for Water Main and Storm Water Improvements by Christopher B. Burke Engineering Ltd. (CBBEL) was approved at the May 16, 2022, Board meeting. Phase I of the project consisted of lining the watermain running from 80th Avenue, down Wheeler Drive, to Elevated Tank #5 at Wheeler and Harlem Avenue.

Due to various delays related to weather conditions, material acquisition, and/or utility coordination/relocation, completion of Phases I and II of the project were each delayed by several months.

These delays resulted in additional project oversight hours costing a total of $81,325.00.
Phase III of the project is not anticipated to be delayed, however additional oversight hours have been required due to work beginning two (2) weeks earlier than anticipated, and the contractor typically working ten (10) hours per day rather than eight (8) hours per...
