Pavement Condition Ranking Services

Proposals should address all labor, materials, supplies, equipment, software, mobilization, training and services necessary to execute the data collection, analysis, QA/QC of data, software access & training to complete the project and provide an effective and professional asset management solution. Project Initiation – Selected Vendor shall meet with Municipal Staff and review data provided by the Municipality, review database software options and integration with GIS software products, review street network layout and existing road segments, evaluation of streets, previous maintenance program and practices, etc. Review Existing GIS Mapping –Vendor shall work with the Municipal GIS Manager and will ensure roadway data can be coordinated with the current GIS system, using existing road segments in developing a ranking. Brentwood specific unique road segment ID numbers and segment limits shall be used throughout the data collection and evaluation. Failure to provide ranking based on existing road segments will prohibit integration with existing GIS data and cause for reevaluation of segments not correctly evaluated and recorded. Network Referencing – Develop survey routing maps and confirm the linkage of the road segmentation to the Municipal database and GIS for the approximately 470 lane miles (or approximately 220 centerline miles) to be included in this project. Define how the Municipality would like the road network to be segmented, in customer defined existing road segments. Pavement Condition Data Collection – utilize a sensor-based data collection platform to automatically collect continuous road surface data. At a minimum system should utilize the following sensor technologies: 3D surface imaging technology IMU enabled GPS for geo-locating of pavement and asset information Differential Encoder for linear positioning and vehicle path creation. 360 Degree Camera for Right of Way imagery collection All systems and data streams should be GPS geotagged and time synchronized to within 2 msec. All survey work shall be performed on dry pavement and in lighting conditions that assure usable data. Data collection shall occur between July 1, 2021 and December 31, 2021, with full completion of presentable data no later than February 18th, 2021.
