<br />Project Name: NW 97th Avenue from NW 52nd Street to <br />NW 58th Street Improvements <br />Client: Miami-Dade Department of Transportation <br />and Public Works <br />Roadway Engineering and Right-of-Way Division <br />. Fernando Mardones, Plans Review and Design 111 NW 1st Street, <br />Miami, Florida 33128 <br /> 305-375-4455 <br />Project <br />Description: Roadway expansion, sidewalk construction, <br />drainage improvements, underpass modification. <br />Nelco Fees: $9,627 <br />Project Dates <br />(Nelco Services): Nov. – Dec. 2018 <br />Nelco <br />Key Personnel: Ulysses Batista <br /> Riza Hosein, P.G. <br /> Ulysses Batista, Jr. <br /> <br />Project Description: <br /> <br /> The project was approximately 0.37 miles in length, along <br />the NW 97th Avenue from NW 52nd Street to NW 58th Street. <br />The project consists of widening from a 2-lane to a 4-lane <br />divided road, sidewalks, golf cart underpass modification, <br />curb and gutters, bike lanes, a continuous storm drainage <br />system, pavement markings and signage, signalization, and <br />roadway lighting. <br /> Nelco’s scope of services included Standard Penetration <br />Test as well as auger Borings for subsurface profiling, sampling <br />and structural stability of in-situ soils. SFWMD specified <br />percolation testing (hydraulic conductivity) for drainage design <br />was also performed. <br /> Fieldwork involved underground utility location, layout <br />coordination, MOT procedures, and drill crew and equipment <br />mobilization. Retained samples were also tested for grain size <br />distribution (sieve analysis) <br />Preparation of a geotechnical <br />engineering report was furnished <br />summarizing field data and <br />interpretations, groundwater conditions <br />project scope and providing geotechnical <br />recommendations for layered-asphalt <br />system construction and placement <br />procedures, soil improvement/land <br />development recommendations and <br />foundation bearing capacity, including engineered fill material specifications for type and <br />placement procedures was also provided including lateral soil and design parameters for retaining <br />wall construction. <br />102
