April 6, 2022 / Page 4 of 12 11723.02 — New Park at Ritz Carlton Sales Center Site City of Sunny Isles Beach The borings will be drilled utilizing the rotary wash method with a truck -mounted drill rig. Samples of the subsurface materials encountered will be collected continuously down to 10 feet below ground surface. Below that depth the sampling will be performed at roughly 5 -foot intervals. Sampling,will be performed using a Standard Penetration Test (SPT) sampler per ASTM D-1586. Upon completion of the borings, the boreholes will be grouted to the ground surface. 2. In addition to the borings, we propose performing two (2) field permeability tests to provide information for drainage design at the site. The tests will be performed to 15 feet below the . existing grade in general accordance with the South Florida Water Management District's Usual Open Hole Procedure. Upon completion of the tests, the boreholes will be abandoned with grout to the ground surface. Test locations can be coordinated with the project civil engineer as appropriate. 3. For performing the fieldwork, NV5 will contact Sunshine One Call for advice about the location of underground utilities. Additionally, we require that any other available information regarding the location of underground utilities be provided to us. NV5 cannot be held responsible for damage to below ground structures or utilities that are not identified to us. We specifically request any available information about the location of underground utilities for this project. 4. An NV5 representative will layout test locations based on the furnished drawings. NV5 will perform borings in areas that are indicated to be free from underground utilities. 5. We note that the site is an active facility. We will rely on the client to provide all necessary site contact information for NV5 to efficiently execute the field work. Site contact name and contact information will be required prior to starting our field work. While NV5 will make reasonable efforts to minimize disruption to any site daily activities, it should be understood that NV5 could need to occupy parking and drive areas for execution of the work. Additionally, drilling is an inherently noisy and messy operation. While NV5 will make reasonable efforts to clean the drill locations upon completion of the work, some soil residue could remain at the ground surface. It is our experience that such soiling is typically washed away by rain showers over time. 6. Based on our field data we will perform engineering analyses and prepare an engineering report with evaluations and discussions of the geotechnical aspects of the proposed development, and provide geotechnical recommendations for design and construction. Specifically, the report will provide: • Drawings showing test locations, a graphic summary of the generalized subsurface conditions, and boring logs with detailed descriptions of the materials encountered. • Discussion of generalized subsurface conditions at the site including groundwater including hydraulic conductivity. • Discussion of feasible foundation type(s) for the proposed construction. • Design parameters for the recommended foundation type, including vertical and lateral load resistance. • Estimates of foundation settlements. • Modulus of subgrade reaction for any slabs on grade. • Recommendations for pavement thickness design • Recommendations for site preparation and grading, including the re -use of site -excavated materials for fill, fill placement and compaction, and slab and pavement subgrade preparation.
