Explanation
1. BACKGROUND:
A. Need. This legislation authorizes the Director of Public Utilities to modify the professional engineering services agreement with CH2M Hill, Inc., for the Southerly Wastewater Treatment Plant Sludge Thickening Improvements and Additional Renovations Project. The CH2MHill, Inc. modification amount requested under this ordinance is $1,419,870.00. The contract total including this modification is $10,330,197.00.
