Engineering Proposal.

On July 13, 2011 City Commission authorized staff to negotiate an Engineering Services Contract with Bartlett & West for the Iowa Street project (memo attached).  Public Works staff and Bartlett & West have thoroughly reviewed the scope of services for the project.  Since this project has $4 million in Federal funds ($3 million STP and $1 million Safety) and is a state highway the project will be let by KDOT and KDOT will have oversight of the design.

 

Attached is the Scope of Services including survey, horizontal/vertical alignment, traffic control, typical section, plan/profile, utility locates, stormwater drainage design/analysis, erosion control plan, detail sheets, signal timing, earthwork quantities and estimates for field check, and final plans. 

 

The proposed engineering design service fee for Bartlett & West to prepare a complete set of plans and specifications, including KDOT review and approval, is $394,170.  This fee also includes a public information meeting and easement services (right-of-way strip maps and descriptions) not included in the Design Fee Guidelines.  Evaluating this fee to the Design Fee Guidelines would include:

Estimated Construction Cost

$5.6 million

Fee Proposal

$394,170 plus $33,575 for already contracted survey

Total Engineering Services

$427,745 (7.6%)

Based on the complexities of this project and state review/oversight the fee is appropriate for the scope of services and in accordance with the Design Fee Guidelines.

 

The City will hire a geotechnical firm under separate agreement to conduct soil/base investigation/analysis.

 

Project Status.  We would like to bid this project in 2012.  This spring staff will be working with the University Neighborhood to develop a traffic calming plan. 

 

Action Requested.  Authorize City Manager to execute an Engineering Service Agreement with Bartlett & West for Design Services for Iowa Street Reconstruction, Project PW1012, in an amount of $394,170.

 

Respectfully submitted,
