SUBJECT:
title
Consideration of Professional Services Agreement (COF Contract No. 2019-0091) with CDM Smith, Inc. for the Robinson Lake Dam Rehabilitation Project in an Amount Not-to-Exceed $602,300.00 (CIC 3/28/2019 4-0)
body
Purpose
The purpose of this memorandum is to report to the Franklin Board of Mayor and Aldermen (BOMA) consideration COF 2019-0091.
Background
In December of 2017, the City finalized the purchase of the Robinson Lake property for $500,000. Prior to closing on the property, CDM Smith and the City conducted a “due diligence review” of the property that identified two concerns. The primary concern is the condition of the Robinson Lake dam. A secondary concern, which could be addressed during dam repairs, is the relatively shallow depth of Robinson Lake.
It is important to note that City staff anticipates expenditures to improve the dam and meet regulatory requirements as outlined in the study completed by CDM Smith. At the current dam classification, full mitigation of the dam deficiencies is projected to cost up to $2.5 million. In reviewing these costs with the consultant, it is anticipated that these costs can be reduced through both value engineering and by pursuing a modification of the dam’s classification with the Tennessee Department of Environment and Conservation (TDEC). Based on feedback to date, the change in classification of the dam can likely be accomplished through further modelling of the dam’s potential impact (or lack thereof) in a flooding/failure scenario.
The purpose of this proposed agreement is for performing final design of the rehabilitation measures for Robinson Lake Dam.
Financial Impact
$602,300 to be paid out of the CIP Project fund.
Recommendation
Staff recommends approval of COF 2019-0091.
