ACID, the Advanced Construction Image Dataset Suite (formerly known as the Alberta Construction Image Dataset), is a community-driven open data platform that provides high-quality training resources and examples for applying artificial intelligence (AI) in construction engineering. Currently, ACID hosts three construction AI datasets including object detection, instance segmentation, and image captioning, along with corresponding data, annotations, guidelines, and algorithm analysis results. The overarching goal of ACID is to foster an open data-driven and self-sustaining open-source ecosystem for construction engineering and management.

Construction Applications Powered by ACID
AI algorithms can automatically identify construction objects/instances/scenes in images and videos through parallel computation and graphic card implementation. However, they require large-scale datasets to mitigate the overfitting problem during the training stage. Since construction sites are often challenging to access, creating extensive datasets containing high-quality construction data poses a significant challenge. The construction community faces a critical barrier, which is the lack of standardized, high-quality, and domain-specific open data resources. This fragmentation undermines reproducibility, slows innovation, and prevents the construction community from developing benchmark tasks that can drive rapid progress
ACID dataset suite was developed as one of the first pioneering open-source artifacts in construction community. Its novelty lies in providing the community with: 1) construction-specific AI research and education resources; 2) benchmark tasks and algorithm analysis to ensure reproducibility and reusability of construction AI research; and 3) annotation guidelines to standardize the creation of future datasets. Through years efforts, ACID has established a transformative foundation for construction AI. The following videos showcase various AI applications backboned by ACID in construction.

ACID Statements
ACID Dataset Suite
ACID suite provides image dataset, guidelines, and algorithm analysis results for training AI models in construction automation. The development of ACID has experienced several stages and various researchers have contributed to it (see here for development roadmap of ACID). The intellectual property of ACID belongs to the ACID group, which is not affiliated to any specific university/institution.
ACID Group
ACID group is a group of researchers from North America, Asia, and Australia (see ACID people) working together to push the boundaries of AI in Construction. The ACID group is currently taking the responsibility to maintain and develop ACID.
