City of Sunny Isles Beach, Florida Marine and Coastal Professional Engineering Consulting Services (CCNA) | RFQ No. 18‐02‐01 Aptim Environmental & Infrastructure, Inc. 10 01C032018D Physical Data Collection The purpose of this task is to acquire the physical data on the coastal processes necessary for the design of coastal protection projects. Physical data may include topographic and bathymetric survey, geotechnical data, wave climate and historical winds, and aerial photography. This data will be used to develop the design criteria that will govern the final design of the project. Where possible, any previously collected data and analysis will be used in lieu of new data collection as a cost saving measure. Due to the detailed needs of designing waterfront projects for permitting and construction, updated, site‐specific data collection efforts are to be anticipated. APTIM has extensive field data collection capabilities. Our survey group can determine the scope of the required data, collect and reduce the data, incorporate the data into a GIS system, and apply the data in support of the project permitting and design. Employing our own field data collection group allows the project managers to more closely control the scope, timing, and most importantly the quality of the data collection efforts. The following is a description of how we would approach collecting the various data sets: Bathymetric and Topographic Surveys Our surveyors have an extensive history of surveying in south Florida. We also review newly collected data with historic data as part of our QA/QC protocol. We own and operate RTK (real time kinetic) GPS equipment, which is the most efficient, accurate, and cost effective surveying technique. We also ensure that there is an overlap between bathymetric data collected using a rover and data collected using hydrographic techniques. This provides another level of data quality assurance. Most waterfront structure design requires surveys extending beyond wading depth. APTIM owns and operates survey vessels capable of performing single beam or multi‐beam bathymetric surveys. The boats are also equipped with an RTK system that provides centimeter level horizontal positioning accuracy and when combined with our heave, pitch, and roll compensator, provides excellent vertical accuracy. This also avoids the need to tide correct data, resulting in efficient data reduction. Our survey crew is experienced in surveying nearshore and inshore waters, borrow areas, and inlets. APTIM also has extensive experience with the collection, reduction and analysis of LiDAR data. This data is collected from an airplane and collects a bathymetric point at densities that can exceed one point every Topographic survey of coastal structure. APTIM conducts offshore biological monitoring and bathymetric surveys using in‐house research vessels and staff.
