RFQ# 18-05-24 Architectural and Engineering Consulting Services: Construction Testing and Inspections RFQ# 20-70-01 Continuing Professional Consulting Services Design-Build Rehabilitation of West Bridge and Bear Cut Bridge on Rickenbacker Causeway, Miami-Dade County, FL Unknown Bridge Foundation: When an existing bridge has an unknown foundation (including type, length, and pile capacity of existing piles), upfront evaluation and exploration is often necessary. This information provides the design team with critical information. For instance, for a bridge replacement, this information determines how close the new bridge can be built without encountering any problems or effecting the existing bridge (which is especially necessary when the existing bridge is continuing to be used during construction). TSF’s past Unknown Foundation Study experience includes: Design-Build Rehabilitation of West Bridge and Bear Cut Bridge on Rickenbacker Causeway, Miami-Dade County, FL; SR-80/Southern Boulevard Bascule Bridge, Palm Beach County, FL; Andrews Avenue over C-13 Canal Bridge, NE 23 Avenue over Rio Giraldo Canal, NE 26th Terrace over Rio De Sota, Laguna Terrace over Diane River, West Lake Drive over Estelle River, West Lake Drive over Diane River, West Lake Drive over Lucille River, Johnson Street over C-10 Canal, and Kings Highway over Belcher Canal, Broward County, FL.
