A. Issue
Approval to execute an amendment to the professional services agreement with raSmith related to the design of Watertown Plank Road and N 115th St Utilities & Paving project (CIP Project 1025).
B. Background/Options
In March 2024, a professional services agreement was executed with raSmith for design services related to the Watertown Plank Road and N 115th St Utilities & Paving project (Common Council Resolution R-24-052). Significant design scope additions resulted from two specific areas of the project.
First, the request for proposals (RFP) included a limited storm sewer design scope due to the many unknowns associated with the existing storm sewer system and the potential required improvements. The priority was completing stormwater modeling for the entire drainage basin to identify recommended improvements for Watertown Plank Road and the required final design effort.
Second, the multi-use path on N 116th St, not part of the original design scope, was added during design to create a connection between the proposed bicycle and pedestrian facilities on Watertown Plank Road with the new Firefly Grove Park upon construction completion. Finally, additional miscellaneous services beyond the initial anticipated scope were requested during the design process.
Expanded Stormwater Modeling and Final Design (with outfall alternatives) and subsequent ancillary tasks due to the proposed storm sewer layout:
• Additional Stormwater Modeling and Final Design - $101,000
• Additional Sanitary Sewer Relay Design - $6,700
• Additional Water Main Relay Design - $4,545
• Permitting and Easement Coordination for the Proposed Outfall on Milwaukee County Property - $9,000
• Traffic Signal at N 113th St - $10,000
Adding the 2,600-foot long multi-use path along the east side of N 116th St:
• Design of N 116th St Multi-Use Path (Watertown Plank Rd to Walnut Rd) - $26,500
• Additional Road Reconstruction Design - $7,500
Various Miscellaneous Design Items (tree planting plan, evaluation of pump station electrical setup and backup power for signals, concrete barrier/guardrail at STH 100/Mayfair) - $9,000
Design Credits for Items in original scope not completed - temporary traffic signals, quiet zone updates, Oak Leaf Trail detour - ($23,000)
The total cost for the additional design scope items is $174,245. Applying design credits of $23,000, the net requested amendment is $151,245.
C. Strategic Plan (Area of Focus)
Priority 2: Public Safety, Goal 2 - Proactively address pedestrian, bicycle and vehicular safety.
Priority 3: Infrastructure, Goal 1 - Optimize infrastructure to handle 100-year weather events.
Priority 3: Infrastructure, Goal 2 - Ensure the City’s infrastructure supports public health through multi-modal transportation and recreation opportunities.
D. Fiscal Impact
The original agreement amount was $350,000. The additional scope items total $151,245 for a total revised contract of $501,245. There are sufficient funds within Project 1025 to cover these fees.
E. Recommendation
Authorize staff to amend the professional services agreement with raSmith for a revised total contract amount of $501,245.
