Tiivistelmä
The interest in location-aware software systems has been steadily rising over the past years and there is a need for a fully-fledged location-aware solution for construction sites. This thesis reviews the literature of different positioning technologies in order to find the advantages and disadvantages of each technology on construction site use. The review is conducted in order to answer which of the technologies and solutions are best suited for different construction site uses as well as how they can improve the safety and efficiency of the site. For indoor use, the best suited technologies for construction site is the fusion of ultra-wideband and wireless local area network-based localization and the minimum accuracy needs should be 1.32 meters. The best solution for outdoor use the fusion of inertial measurements and GPS-based localization and the minimum accuracy should be 5 meters. The suggested solutions would be feasible utilizing technology that is already in use for the most part, such as heavy machinery sensors and smartphones that the workers carry with them.
The review of the location technologies and solutions is also applied to answering how to improve the safety and navigational efficiency of the construction site through different possible implementations. Safety of the construction site could be improved by utilizing virtual boundaries and automated alarms based on position, velocity and movement direction. Snapshots of the construction site state could be stored, which include information about the location of each entity on the construction site at time of the snapshot, which could be used to review accidents and close-call situations.
Navigational efficiency could be improved by tracking the location of workers, machinery and tools on the construction site. The thesis also suggests estimating the location of a worker with different means when the positioning data is not available.
