<br />Review and Analysis of Existing Conditions
<br />
<br />· Define topographic and boundary survey requirements,
<br />· Review historical surveys and determine the need for supplemental boundary and topographic surveys.
<br />· Identify existing site constraints (traffic, existing utilities).
<br />· Inspect existing site conditions such as site grading and drainage patterns, The initial site visit will be critical to identify any additional
<br />issues/components that should be addressed during design for regulatory compliance with emphasis on drainage and stormwater
<br />management.
<br />
<br />Geometries
<br />
<br />Existing roadway features need to be checked against applicable design criteria (i.e. FOOT PPM, AASHTO Green Book, etc,) and brought up to
<br />standards if deficient. Some potential horizontal and vertical geometry issues encountered are:
<br />· Insufficient sight distance at intersections
<br />· Gutter grades of less than 0,3%
<br />· Substandard turning radii for large vehicles
<br />· Narrow driving lanes
<br />· Vehicle storage at intersection turning lanes.
<br />
<br />Pavement Design Package
<br />
<br />Our Team can provide the City with our recommendations and if necessary create a pavement-design report following the procedures developed by
<br />the Florida Department of Transportation, The pavement design of any roadway should be sensitive to the number of vehicle trips, percent of trucks
<br />using the roadway, expected life of the pavement, and existing subsoil conditions.
<br />
<br />Utility Data Collection
<br />
<br />Projects assigned will be located in fully developed areas of the City of Sunny Isles Beach; congested with existing utilities (Gas, FPL, Telephone,
<br />Cable TV, etc.). As a result, accurate mapping of existing above & underground utilities is imperative to avoid utility conflicts, schedule overruns and
<br />potential change orders during construction, The Lochner Team will perform the following during these task assignments:
<br />· Obtain a Design Ticket from One Florida Sunshine, Inc, identifying the utility companies (gas, telephone, etc) providing service
<br />within/adjacent to the project limits then forward Request for As-Built Records to each utility company,
<br />· Obtain drainage, signalization, roadway lighting as-built/records from Miami-Dade County Public Works and the City of Sunny Isles Beach
<br />Public Works,
<br />· The Lochner Team will coordinate planned/future roadway, drainage, utility, private developments with Miami-Dade County Growth
<br />Management Division as well as City of Sunny Isles Beach, as applicable for the project location. The objective of this task is to ensure that
<br />the construction schedule of the proposed work does not impede; or is impeded by, planned/future private and public infrastructure
<br />improvements within the project limits,
<br />
<br />Geotechnical Exploration & Evaluation
<br />
<br />Once route surveys have been performed and areas of improvements established, the Lochner Team will request a geotechnical exploration and
<br />soils evaluation to obtain information regarding subsurface soils, ground water levels, provide soil bearing capacity evaluation with recommendations
<br />for site preparation and compaction and drainage testing.
<br />Based on the current understanding of the project's magnitude and complexity, the Lochner Team envisions design submittals (60% and Final)
<br />during the design phase of the project.
<br />
<br />Roadway Design
<br />
<br />.
<br />
<br />The Lochner Team will develop roadway and pertinent details consistent with the
<br />content for each submittal stipulated/required by the City and conforming to the
<br />latest update of the Stormwater Capital Plan.
<br />The Lochner Team will prepare technical specifications per FOOT standards and as
<br />required by the City of Sunny Isles Beach,
<br />The Lochner Team will coordinate with the Prime, Maintenance of Traffic Plans per -.)'!J1"').,.-~,,--; ,r 1... 'f.-
<br />Miami-Dade County, City of Sunny Isles Beach and FDOT District 6 requirements, II'
<br />as applicable to the project with emphasis on public safety, adequate
<br />ingress/egress to impacted merchants/residents and businesses,
<br />The Lochner Team will prepare detailed cost estimates and update project schedule to include Preliminary Construction timeline,
