Abstract

On construction sites, there are unsolved security concerns. Equipment misplacement and theft, labour fraud and regulatory constraints require construction companies
to keep a close watch on personnel and equipment, in order to prevent unnecessary costs. Due to the opaque nature of constructions sites and their workflow, this is
very labour-intensive to achieve, mitigating the potential savings.
Video surveillance partly solves this problem by keeping watch over construction sites for undesired activity, however much of unwanted activity remains unseen by cameras. A localisation system is required to keep better track of people and equipment, however the constraints imposed by typical construction sites prevent us from
using existing localisation systems. The localisation system should be low-cost, low-infrastructure and low-maintenance.
We show that our design is capable of fulfilling these requirements, among others, and achieve good progress towards an acceptable accuracy. The solution we devise
is capable of working with only a single reference node position, low-cost blind nodes without any meaningful processing power, and without an extensive set-up
and calibration phase. Our study includes field tests to measure the performance of the design.
