Synthesis of Information Related to Highway Practices. Topic 50-12. How Was it Built? State of Practice for As-Builts Plans on Highway Projects

The development of as-built plans has long been the method used to capture, document and preserve construction changes, additions or details that were not previously depicted on the original construction plans. As-built plans are used by operations and others in the maintenance, repair, widening and rehabilitation of constructed transportation facilities. Over the past decades, various advanced and emerging technologies have been adopted in the transportation industry to improve the accuracy and efficiency in design and construction, which includes GPS, LiDAR, and information modeling. Migration to electronic plans and 3D models increases the information included on the construction plans and thereby As-Built plans have evolved with the directive to include more information with improved accuracy. Yet with current technology, some agencies continue to hand draw information on paper plans. As-built or as-constructed plans are customarily developed for transportations projects. However, the content, accuracy, format and platform vary across agencies and may also vary pending the project delivery method (e.g., Design-Bid-Build vs. Design-Build). The objective of this synthesis is to evaluate the state of the practice for as-built plans for highway projects.
