Title
Resolution to Ratify an Emergency Purchase Order Increase with C.A. Hull Company, Inc. for the Wastewater Treatment Plant 2020 Access Bridge Repair Project ($23,471.30)
Memorandum
On June 1, 2020, Council approved a contract in the amount of $114,139.58 with C.A. Hull Company, Inc. (C.A. Hull) to construct the Wastewater Treatment Plant (WWTP) 2020 Access Bridge Repair Project and a contingency of $17,000.00 for changes approved by the City Administrator (R-20-188, attached). As part of the bridge repair work, damaged portions of the concrete bridge deck topping were saw cut, chipped, and replaced on September 19, 2020. During this one-day project, which required the bridge to be closed to vehicular traffic, C.A. Hull discovered that the upper four inches of topping needed to be removed compared with two inches estimated by the City's design engineering firm. Therefore, added costs that exceeded the $17,000.00 contingency for this project were incurred.

Consequently, it was necessary to request the City Administrator to approve an emergency purchase order increase in the amount of $23,471.30 with C.A. Hull. This emergency request was made and completed on November 2, 2020 (attached). This purchase order increase is to be funded from the $17,000.00 approved project contingency and City staff is requesting Council approve the additional $6,471.30 from the sanitary sewer system fund that is needed to pay for the additional work.

In accordance with approved Administrative Policy and Procedure No. 204 and City Code, Chapter 14, 1:317 Emergency Purchases and Contracts, City staff is now reporting this purchase to you and requesting authorization of same.

Budget/Fiscal Impact: Funding for this additional work is available in the Sewer Supply System Capital Budget.
