Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 3 with K. Friese + Associates, LLC for the Greenlawn Boulevard Widening - SH 45 to IH 35 Project.
Body
The Greenlawn Blvd. Widening Project will add one 11-foot wide travel lane in each direction and a separated 8-foot bicycle path along Greenlawn Boulevard from IH-35 to SH 45. The existing roadway is a four lane divided arterial. The project is anticipated to be completed by widening both road beds to the north and installing the bicycle path 5 feet from the back of curb along the north side. Project length is approximately 1.0 mile. The City of Round Rock Transportation Master Plan shows this section as a 6 - Lane Enhanced roadway.
This is the third supplemental to the agreement approved by Council on October 24, 2019, which provided for K Friese & Associates, Inc. (KFA) to perform Preliminary Engineering design services.
Supplemental Contract No. 1 covered engineering for final design and construction phase services.
Supplemental Contract No. 2 was for design of stormwater detention, and producing a Conditional Letter of Map Revision (CLOMR) and Letter of Map Revision (LOMR) for a floodplain permit from FEMA. The additional services were added to provide detention for the roadway project and to mitigate for the improvements that were made within the floodplain by Whittlesey Landscape Supplies.
Supplemental Contract No. 3 is for the design of waterline relocations in conflict with the road design. The water mains in conflict will require adjustment so KFA will develop Plans, Specifications, and Estimate (PS&E) documents for the adjustment of two 12-inch water mains, one 8-inch water main and four 16-inch water mains.
With the addition of this supplemental contract, design fees for the Greenlawn Boulevard Widening project are as follows:

Supplemental #1: $820,982.00
Supplemental #2: $222,010.00
