This paper proposes a framework to automatically quantify the quality of rebar placement in
the field to improve construction quality and long-term durability of the bridge structures. In …

Abstract When constructing Reinforced Concrete (RC) components, rebar spacing must be
inspected in the field before pouring concrete. The traditional inspection of rebar spacing:(1) …

Inspecting the diameter and spacing of rebar is an important task conducted by fabricators
and site engineers during the manufacturing and construction stages. This is because the …

The inspection of rebar diameter prior to concrete pouring is a crucial step for inspectors and
fabricators to check the compliance to the designed bearing capacity and structural integrity …

The reinforcement of bridge girders is critical to ensuring adequate strength, serviceability,
and durability. Achievement of these criteria is assessed by quality control processes …

Dimensional quality assessment (DQA) on the formwork and rebar of a reinforced concrete
(RC) element is an important task for factory or field inspectors to ensure compliance with …

As-built BIM is a relatively new concept to the AEC/FM industry and has not been applied to
many project elements yet, including structural components. The conventional methods of as …

Accurate data collected from on-going construction projects assists project field engineers
with tracking the progress of construction work. The comparison of as-planned schedules …

This work presents a process for automated end-to-end inspection of area defects—
specifically spalls and delaminations—in RC bridges. The process uses a mobile robotic …

Assessing vertical clearance at bridges is a preliminary step in most routine bridge
inspections. This information is critical when assessing the structural integrity of bridges …
