Article history: Accepted 11 February 2008 Construction projects are information-intensive in nature and require site personnel to have continuous ondemand access to information such as project plans, drawings, schedules, and budgets. Awareness of a user's context (such as user profile, role, preferences, task, and existing project conditions) can enhance(More)
This paper describes research that investigates the application of Augmented Reality (AR) in 3D animation of simulated construction operations. The objective is an AR-based platform that can be used together with corresponding equipment (HMD, GPS receiver, and a portable computer) to generate a mixed view of the real world and superimposed virtual(More)
During a typical excavation operation, there is a high risk of inadvertently damaging the existing subsurface utilities. Such incidents cause significant financial loss to the project and can delay or abruptly halt ongoing construction. In many cases, they also pose a life threat and often result in accidental deaths. As a result, constructors are required(More)
This paper describes research that investigated the application of 3D Augmented Reality (AR) for animating traffic simulation models in real time to support the planning and design of road construction projects. Traditional 3D visualization applications use Virtual Reality (VR) environments to visualize traffic simulations. The significant amount of time(More)
This paper describes research that investigated the applicability of 3D Augmented Reality (AR) in visualizing dynamic engineering operations. The research resulted in the design and development of ARVISCOPE, a general purpose high level AR animation scripting language, and ROVER, a mobile computing hardware framework. When used together, ARVISCOPE and ROVER(More)
In the USA, asphalt tear-off roofing shingle is one of the largest productions in the municipal solid waste (MSW) stream. Applications into road construction materials can be an alternative to recycle these tearoff shingles. This paper discusses the beneficial use of tear-off shingles in Hot-Mix Asphalt (HMA) by presenting: (1) the physical properties of(More)
This paper presents a reusable, general-purpose, mobile augmented reality (AR) framework developed to address the critical and repetitive challenges specific to visualization in outdoor AR. In all engineering applications of AR developed thus far, basic functionality that supports accurate user registration, maximizes the range of user motion, and enables(More)
