Abstract
Current construction worksite layout planning heavily relies on 2D paper media where the worksite planners sketch the future layout adjacent to their real environment. This traditional approach turns out to be ineffective and prone to error because only experienced and well-trained planners are able to generate the effective layout design with paper sketch. Augmented Reality (AR), as a new user interface technology, introduces a completely new perspective for construction worksite planning. This paper disucsses the related AR work and issues in construction and describes the concept and prototype of an AR-based construction planning tool, AR Planner with virtual elements sets and tangible interface. The focus of the paper is to identify and integrate worksite planning rules into the AR planner with the purpose of intelligently preventing potential planning errors and process inefficiency, thus maximizing the overall productivity. Future work includes refining and verifying AR Planner in realistic projects.
Highlights
Worksite planning of construction resources includes the design of construction worksite as well as the optimization of resource logistics.Nowadays, construction projects are in need of short duration, which necessitate a fast and flexible strategy for planning construction worksites
Augmented Reality, which appears in the literature usually in conjunction with the term Virtual Reality (VR), is a technology or an environment where the additional information generated by a computer is inserted into the user’s view of real world scene (Milgram P. & Colquhoun, H., 1999; Azuma, R.T., 1997)
This paper introduced a new concept of an Augmented Reality (AR)-based construction worksite planning system, AR Planner and presented the preliminary work associated with AR Planner
Summary
Worksite planning of construction resources includes the design of construction worksite as well as the optimization of resource logistics. Current construction worksite layout planning heavily relies on 2D paper media where the worksite planners sketch the future worksite layout adjacent to their real environment. This traditional approach turns out to be ineffective and prone to error because only experienced and well-trained planners are able to generate effective construction layout design with paper scratch. Collaboration among parties from different levels involved in the planning process cannot be well supported due to the lack of effective visual rendering inherent in the traditional paper media. AR allows a user to work in a real world environment while visually receiving additional computer-generated or modeled information to support the task at hand. Users could move and position these items interactively to design and determine the configuration of the construction worksite
