D Project Approach and Understanding Terracon has performed several canal slope stabilization projects for various municipalities. Access to locations for such projects is generally behind existing structures. Terracon understands the need to coordinate with private owners while performing field work. We are aware of the vibration concerns for installation of sheet piles in close proximity to existing structures. Our engineers work closely with the designer and provide the most cost-effective approach for stabilization of slopes. Construction on sites which were previously used for different purposes pose a big concern especially if the site was used as a borrow pit and was backfilled without any control with construction debris or unsuitable fills. Terracon has worked on several such sites and will provide most economical ground improvement technique to address any unsuitable fill concerns. ,. , 4M1 We recognize that time is of the essence for any project especially during construction. During construction, we will assist with responses to 77 I requests for information (RFIs) for geotechnical issues, provide specialty in-situ testing, dynamic pile testing (PDA/EDC), Case Pile Wave Analysis Programave Equation Analysis Program (Analysis, pile driving plan will gin' VF4 1 { review and inspections, drilled shaft plan review and independent assurance inspection by CTAP -certified staff, auger cast pile installation plan review and inspection, and testing services for crosshole sonic logging (CSL), Thermal Integrity Profiling (TIP), pile integrity test (PIT), and vibration monitoring. Roadway Reports - Roadway projects may consist of new roadway, widening, reconstruction, and/or milling and resurfacing, pavement distress and/or subsidence. Laboratory testing is very important for a roadway project, since utilization of the existing soils within the embankment and subgrade portion of the road needs to be determined. During roadway geotechnical design, critical issues that may impact the existing or proposed roadways include: site history, problematic soils (plastic/organic soils, and/or uncontrolled fills [trash, dredge soils, etc.]) and high groundwater elevation. Soil improvement methods will be considered for problematic sites when most economical and/or practical. In addition, Terracon can perform pavement evaluations and provide geotechnical recommendations for new pavement design or rehabilitation. Drainage design parameters will be provided by performing permeability and infiltration testing for French drains or retention and detention ponds. Structures Reports - Structures projects typically consist of bridge foundations, building foundations, walls, signs and other miscellaneous structures. Critical geotechnical issues requiring special attention consist of preforming for foundation installation, need for temporary or permanent casing for drilled shafts due to hole cave-in or adjacent existing foundations, loss of drilling fluid/rock porosity, and impact of shallow groundwater. The proper geotechnical evaluation and recommendations for these issues will avoid potential construction delays or claims to the City. lrermcon City of Sunny Isles Beach — RFQ No. 20-07-01 1 Continuing Professional Consulting Services (CCNA) 11
