DESCRIPTION/BACKGROUND:
On February 20, 2024, the Board of County Commissioners (BCC) approved a Request for Qualifications (RFQ) and awarded a contract to Kittelson & Associates, Inc. to design and prepare construction plans for elevating CR 475A (aka SW 27th Avenue) from 0.7 miles north of SW 66th Street to SW 42nd Street and to conduct an intersection study, analysis, design, and provide construction plans for CR 475A at SW 66th Street. The RFQ also provided for future work including the preparation of a Preliminary Engineering Report (PER) for the CR 475A four-lane widening project, and all documents associated with the work.
Change Order 4:
During the design process of the elevated roadway portion of the project, the need for a Pumping Analysis was identified. This work was included in the original contract as an Optional Task under Exhibit B - Fee Schedule, Task A.
The Pumping Analysis will:
• Estimate expected stormwater runoff and potential flood impact in a storm event
• Evaluate the performance and impact of the existing Drainage Retention Area (DRA)
• Analyze potential pumping scenarios and recommend an appropriate pump selection
• Develop recommended operating procedures for pumping operations
Change Order 5:
It was determined that a PER for the intersection of CR 475A and SW 66th Street was needed for this portion of the project. This work was not included in the RFQ scope and is separate from the future CR 475A four-lane widening PER. This PER will evaluate alternative intersection improvements to enhance operations and safety with the following:
• Analyze traffic operations and safety conditions
• Evaluate improvement alternatives
• Provide concept plans
• Develop cost estimates
• Identify right-of-way impacts
• Conduct public involvement activities
• Prepare and finalize the PER
The Change Orders, exhibits, and maps are attached for review. Upon approval at today’s meeting, the Change Orders will be presented to the Chairman for signature.
