Tab 4 - Approach / Methodology
<br />• Traffic control and property-access needs; and
<br />• Professional certification and schedule requirements.
<br />Records research may include plats, deeds, title information, right-of-way maps, benchmarks, prior
<br />surveys, utility records, control information, flood information, elevation certificates, and available City
<br />GIS data. Field reconnaissance will verify control, access, physical obstructions, traffic and pedestrian
<br />exposure, feature density, and the most suitable collection method.
<br />Field Data Collection and Technology
<br />CTS will select the combination of conventional surveying, robotic total stations, digital levels, GNSS,
<br />mobile or terrestrial LiDAR, hydrographic equipment, and GIS-enabled data collection appropriate to
<br />the assignment. Technology will be applied with professional judgment to improve coverage, reduce
<br />exposure of crews within active streets, limit repeat mobilizations, and provide accurate information that
<br />can be immediately used for design, permitting, construction, maintenance, and asset management.
<br />In Sunny Isles Beach, particular attention will be given to reliable vertical control and elevation data
<br />supporting:
<br />• Drainage and pump station improvements;
<br />• Conversion of gravity wells to pressurized systems;
<br />• Flood-risk and adaptation planning;
<br />• Roadway and sidewalk profiles;
<br />• ADA-accessible routes and curb ramps;
<br />• Utility and structure elevations;
<br />• Elevation certificates;
<br />• Coastal and waterfront infrastructure; and
<br />• Repeat monitoring of settlement or infrastructure conditions.
<br />Survey data will be structured, when requested, for integration into the City’s GIS and infrastructure-
<br />management systems. Consistent feature coding, metadata, datum information, control descriptions,
<br />and electronic formats will allow data collected for an individual assignment to support future Citywide
<br />planning and asset-management needs.
<br />Survey Quality Assurance
<br />Quality begins in the field through verified control, redundant observations, closure checks, proper
<br />coding, field documentation, equipment verification, and secure data transfer. Office processing will
<br />include adjustment and closure verification, comparison with source documents, review of point-cloud
<br />extraction, digital terrain model checks, CADD and GIS review, and confirmation that required features
<br />and metadata are complete.
<br />An independent senior survey professional will review the work before delivery. Signed-and-sealed
<br />products will be provided when required. For accelerated assignments, field collection and office
<br />processing may proceed concurrently, but final deliverables will not be issued until the required
<br />professional and QA/QC reviews are complete.
