Field Data Collection and Management Services
RJN staff has evaluated over 250 million feet of deteriorated wastewater lines and manholes to determine the most effective method of rehabilitation, repair, or replacement. The condition of the existing sewer lines drives the decision about the type and design of these improvements.
Incomplete or inaccurate condition assessment presents a serious risk to the project’s success. RJN’s trained and experienced field crews can perform the field inspections necessary to provide a strong data foundation. Building on this foundation, using time tested and validated data analysis techniques and engineering principles, the RJN team will accurately determine the performance capability and integrity of existing sewer lines.
During the condition assessment or flow monitoring program, RJN`s data analysis group utilizes RPM (RJN Project Management) Software to streamline the sanitary sewer data collection, managment, and analysis process.
Flow Data Collection and Analysis - RJN uses the Telog Enterprise tool to capture, manage, and analyze collected flow data. It provides an automated means to collecting, archiving, presenting, and sharing data from flow meters, rain gauges, and SSO surcharge sensors. The Enterprise database is designed to store all collected and computed measurements and data as well as RTU configurations, call schedules, report templates, and log files.
Data Mapping with GPS - RJN field crews use Trimble handheld data collectors equipped with mapping grade GPS receivers and loaded with CartoPac electronic forms to collect manhole inspection, smoke testing, and other pertinent field data. The Trimble unit provides the ability to seamlessly take collected field data and roll it into a GIS or GIS-supported field result database. RJN has customized the data collectors with field dropdown lists that validate data entry and ensure maintenance of data collection standards. This data collection technology eliminates the need for reconciliation and Quality Control steps required with paper records, expediting the field inspection process and ensuring data accuracy.
Project Monitoring - RJN has developed a web-based GIS viewer, RJN Online, which provides client access to data during inspections. Client project managers can monitor project activities, quantify project accomplishments and trends, and query, sort, and group results to support decision-making from early in the process through the end.
Project Data - RJN collects data and incorporates industry-accepted NASSCO PACP/MACP/LACP coding schemas for assessment and prioritization of structural defects. All data can be easily exported and integrated with client CMMS and GIS systems.
