Explanation:
Southern Regional Wastewater Treatment Plant is a 55.5 million gallon per day wastewater treatment facility that uses multiple treatment processes to treat wastewater and produces high quality effluent. The biological treatment process consists of five oxygenation trains and eight clarifiers. Clarifiers No. 5 & No. 6 were constructed in the 1990s and needed extensive rehabilitation.
On April 1, 2020, due to the COVID-19 pandemic, the City Manager approved the contract with TLC Diversified, Inc. (“Contractor”) in accordance with applicable Florida Statutes and the Declaration of Emergency (Memo 20-017) for construction services related to the Clarifier No. 5 & No. 6 Rehabilitation - Phase II project, in the amount of $2,077,010.00, which included a $450,000.00 contingency allowance for unforeseen conditions.
The Department of Public Utilities (“Department”) executed Field Order No. 1 in the amount of $23,114.30 on October 21, 2020, Field Order No. 2 in the amount of $15,400.00 on November 17, 2020, and Field Order No. 3 in the amount of $6,783.76 on June 8, 2021, due to unforeseen conditions related to replacement of a 4-inch gate valve and application of Xypex concentrate coating over Clarifier No. 5 walls, troughs, and trough supports. These field orders were authorized by the Director of the Department of Public Utilities and paid via the Owner’s Contingency pay item in accordance with past practices. As a result, the contingency remaining in the project is $404,701.94.
During the construction, it was discovered that degradation of the steel mechanical mechanism in Clarifier No. 6 is much worse than anticipated and complete replacement of the metal mechanism including rake arms, feed well and walkway supports is required. The Department requested a proposal from the Contractor related to the replacement of the metal mechanism.
Hazen and Sawyer, P.C., the engineer of record, and the Department staff evaluated the scope and negotiated the change order price and have determined that the negotiated cost in the amount of $174,859.51 is reasonable and in accordance with industry standards. The Contractor also requested an extension of the contract time by 105 calendar days due to the manufacturing and delivery of this equipment. This change order will be paid via the Contingency pay item.
This agenda item seeks approval of execution of Change Order No. 1 with the Contractor in the amount of $174,859.51 and to extend the contract term by 105 calendar days to January 3, 2022.
