Proactive Intelligent Construction Site Management Enabled by Automated On Site Monitoring (PRISM)

**PRISM** will develop a digitally-enabled construction planning and management solution that delivers step-change productivity improvements for on-site construction.On-site construction is impacted by multiple issues that can accrue over time to cause overall programme delays and increase project risk. Short-term (Lookahead) planning aims to avoid/minimise these delays by enabling incrementally better decisions on a daily basis. To do this, accurate information on issues such as task progress, resource availability/utilisation and site-specific factors (e.g. materials to be moved, ground conditions, access, weather) is essential. However, to date such information is obtained only via feedback from manual inspection or from 'ad-hoc' updates from site managers after task completion or when issues have already arisen.PRISM addresses this challenge. It builds on opportunities created by digital devices such as fixed and mobile cameras/scanners that enable continuous site monitoring. The use of these new technologies in construction is growing and will accelerate, facilitated by recent innovations such as high speed, low-latency 5G networks. However, these solutions currently require expert staff to monitor/interpret images, potentially leading to data overload (with users unable to know where to focus attention), or limiting their full benefit to specific/focussed scenarios.PRISM will therefore develop an analysis engine that uses AI-based algorithms (applied to filtered/triaged data feeds from on-site monitoring devices) to generate targeted information on critical construction tasks in near real-time. The resulting information streams will be integrated into lookahead planning, enabling site mangers to rapidly react to evolving issues, avoiding time/cost-critical delays by rescheduling activities or reallocating resources. The project will develop a pre-commercial 'minimum-viable-product' solution for rapid deployment and which can be enhanced over time.PRISM will be led by UK SME **Trackchain** (data analytics) with **Glideology** (data collation/triaging) and **Aphex** (lookahead planning), supported by leading construction contractors **BAM** and **Costain**, and the Building Research Establishment (**BRE**).
