REQUEST FOR QUALIFICATIONS NO. 20-07-01 CONTINUING PROFESSIONAL CONSULTING SERVICES (CCNA) TAB D: PROJECT APPROACH AND UNDERSTANDING determining outside diameter and material type. A Test Hole Data Sheet is produced and depicts all discoveries with regards to the excavated utility. Data Collection Survey/Data collection efforts will consist of Survey & G.I.S. personnel obtaining all survey control data for horizontal & vertical locations of all major utilities, storm, sanitary, water, electric, gas, and telecommunications. Storm and sanitary will include information at structures: rim, invert, pipe size and material, direction and condition, if needed. Our crews have collected on both handheld Global Navigation Satellite System (GNSS) Mapping Grade GPS or Survey Grade GNSS GPS units. This will include the latest integrated Trimble Geo 7X GNSS GPS receiver able to delivering up to 10cm real- time or post processed accuracy and/or Trimble R10/R8/R2 GNSS Rover Survey Grade receivers able to deliver centimeter/millimeter accuracy. It has been our experience that the newest GNSS GPS receivers yield the highest-grade accuracy required for this Solicitation and our ability to use multiple units provides us greater flexibility in a project like this. All of our survey data collection technicians at Craven Thompson are experienced with G.I.S. asset inventory projects. Their knowledge yields consistent and dependable execution of their duties while in the field. In addition to scheduling crews, our survey & G.I.S. coordinator perform random audits to ensure that data is collected both according to schedule and project specifications. We manage all aspects of the fieldwork, troubleshooting and resolving any issues that may arise during the collection phase. The collection team will gather information and attributes for the assets required by the City. Our data collection personnel are constantly monitoring GPS status and positional accuracy as they progress along with project area. Craven Thompson will create a template for attribute input applicable to the task to be installed on every data collector with each field technician. Upon recording the position, the technician will enter the mandatory and applicable attribute information into the template. Additionally, the data collection technicians will take a digital photograph of each of the referenced structures being surveyed. This photograph will become part of the G.I.S. database. G.I.S. Database Updates Under the direction of the PM, Richard D. Pryce, P.S.M., our G.I.S. technicians will download the field information collected by the data collection technicians and import it into an initial fieldwork ArcGIS geodatabase where it will be analyzed for data quality, precision, Quality Assurance / Quality Control (QA/QC) and then integrated into the master geodatabase for the project. The geodatabase schema for the utility locates will be based upon standards agreed to with the G.I.S. staff. Craven Thompson will incorporate the information into the existing G.I.S. geodatabase schema to include all attribute data, positional data, photographic data, and other relevant data gathered during the data collection phase. Craven Thompson will utilize their expertise and experience in survey & G.I.S. data collection techniques for conducting the field inspection, collection and QA/QC process. Craven Thompson also has the experience of taking decades of survey and as-built records in both CAD and hard copy format and integrating them into an ArcGIS system database. Our survey & G.I.S. team has recently completed this task for the City of North Miami Beach, covering 42 Sections, and all of utilities at Port Everglades for Broward County. We have developed techniques setting hyperlinks in the G.I.S. database tied directly to the pipe and structure features in the G.I.S. system which makes them more accessible to the people who need them most. We are also experts in D | Page 17
