BACKGROUND
Dakota County is in design phase of County Project (CP) 42-173, which will improve the pavement and signal system along County State Aid Highway (CSAH) 42 (150th Street W) from CSAH 33 (Diamond Path) to Trunk Highway 3 (Robert Trail S) in the Cities of Apple Valley and Rosemount. The project includes pavement milling and overlay, replacement of pedestrian ramps to meet Americans with Disabilities Act (ADA) standards, pavement markings, signal improvements at CSAH 33 (Diamond Path), and necessary repairs to local utility systems.
As part of pavement preservation projects, Dakota County works with municipal partners to identify utility repairs that can be incorporated into County-led construction projects to reduce repeated disruptions, to save time and costs, and to ensure the corridor is improved comprehensively. Potential utility elements include storm sewer, sanitary sewer, and watermain repairs. The pavement along the corridor has reached the end of its useful life and exhibits severe cracking, failing curb, and noncompliant pedestrian features. Accessible pedestrian signals and other system elements will be updated at all signalized intersections.
CSAH funds will be used to deliver pavement and ADA improvements.
The project scope has evolved, and additional design services are required to maintain the planned construction schedule for 2027. Staff requested a quote from WSB, LLC for out-of-scope services required to complete the project for planned construction in 2027 utilizing State funding. The proposed second amendment includes:
• Design add-on for intersection safety improvements at CSAH 42 and Canada Ave. ($58,360)
• Analyzing offset left-turn and right-turn operations at Diamond Path and CSAH 42. ($12,490)
• Incorporating design sheets for offset left-turn improvements at the Diamond Path intersection. ($12,490)
• Coordinating with State Aid and federal aid staff to revise project limits for an adjacent project based on safety improvements involving left- and right-turn lane offsets. ($12,490)
• Adding the southwest trail connection and related ADA improvements. ($6,245)
• Evaluating ADA ramp impacts and right-of-way needs. ($12,490)
• Preparing parcel sketches and conducting additional ROW coordination. ($20,264)
• Tracking State Aid funding for pavement, ADA, and signal improvements. ($3,122)
• Adding trail improvements along the south side of CSAH 42 between Canada Avenue and Trunk Highway 3 (Robert Trail S). ($6,245)
• Providing construction administration assistance for site complexities, construction issues and help mitigate delays. ($15,336)
• Total additional services: $159,532
The original contract included unused tasks at the time of amendment request. The County will receive credits for the unused tasks as part of the second amendment.
• Credit for unused Task 2 Public and Agency Involvement services ($16,468)
• Credit for original 50-hour Construction Supplemental Assistance allowance ($7,668)
• Total credit: $24,136
Net second amendment request: $135,396
