Intelligent construction data collection systems (i.e., geospatial systems such as intelligent compaction, paver-mounted thermal profiling [infrared radar technology], ground penetrating radar (GPR), and pavement smoothness/profile, etc.) gather large quantities of data each day of production activities. Near, ‘real-time’, integrated visualization and analysis systems are required so that materials and construction personnel can rapidly evaluate data and make decisions regarding acceptance.

Using ICDM-Veda as a tool/platform, the objectives of this effort are to incorporate features and enhancements such as the following: • Analysis platforms * Filtering, computations, modeling, etc. • Management of database and project files * Enhancements and additions to existing logic and coding to facilitate efficiency and added features; • Mapping * Mapping performance, print feature; • Correlation analyses * Correlations between different data sets (intelligent compaction, thermal profiling, GPR, pavement smoothness, FWD, density, etc.); • Spot tests * Management of conventional spot test data (import, filtering, mapping, correlations); • Data import and mapping * Import data sets from ProVAL, ground penetrating radar, and delimited text data; • Contract administration * Automated items needed to administer geo-spatial technologies during construction for QC/QA); ? - Data import/mapping, acceptance, basis of measurement and documentation of quantities; • Asset management * Mapping of final project QC/QA data collection for use as a supplement Pavement Management Systems

MnDOT, in collaboration with local contractors and suppliers, is moving forward with full implementation of geo-spatial technologies such as intelligent compaction and thermal profiling (infrared imaging) as quality control tools on grading, reclamation, and asphalt paving projects. Currently, only 10 to 15 percent of the MnDOT 2014 bituminous paving contracts will utilize these technologies due to lack of needed enhancements to the ICDM-Veda for use in contract administration. MnDOT has spent $510,000 to date to create the ICDM platform and the features that are currently available. MnDOT is currently in the process of creating another contract worth $140,000 for enhancements that are needed for implementation during this 2014 construction season. This current platform is being used by nearly 20 other State Agencies for monitoring of geo-spatial projects using intelligent compaction. While these enhancements will be retained and built upon, there are numerous features that have yet to be added to allow for full monitoring, ease of use, automated procedures for cleaning/filtering of data and contract administration of these technologies by project personnel. Intelligent Compaction is currently part of the Every Day Counts 2 (EDC2) initiative, with the objective of moving national implementation efforts of intelligent compaction forward. Consequently, ICDM-Veda, is included in the national training (and is referenced in the AASHTO Provisional Standard PP81-14 “Standard Practice for Intelligent Compaction Technology for Embankment and Asphalt Pavement Applications” and in the FHWA’s boiler plate specifications), as it is currently the only non-proprietary tool available for State Agencies and Contractors to use to view spatial data. In addition to investments to the EDC2 initiative, there has been a large amount of resources put toward researching this tool. The following are a few of the publications reported to assist with implementation efforts.

ICDM-Veda is currently the only non-proprietary tool for visualization and analysis of this technology.
