IoT innovation in the construction sector


 Dempsey Wood is a family-owned innovative civil engineering company that has embarked on a journey to the world of IoT, to help solve noise some of their biggest environmental challenges.

Customer problem

Often the construction sector is challenged by the inability to access real time data to help mitigate negative impact from noise, dust, and vibration which up until recently, required manual testing. Given the scale of construction projects that Dempsey Wood works on throughout the year, the requirement of being able to rely on its mitigation systems to manage complaints and to support internal compliance monitoring has become ever more important.


Industry proven sensors monitor environmental site parameters of noise, vibration and dust. Data from the sensors is passed on to the Adroit platform via the Spark Cat-M1 network, to provide a real time monitoring system. This solution is customisable to specific sites and is modular, cost effective and scalable.


Dempsey Wood now has access to comprehensive real time data on one screen 24/7 with full visibility of particle matter, temperature, noise, and other factors providing them confidence in their control methods, operations, and systems.


IoT to help solve environmental compliance in the construction industry

Employing over 500 staff to-date and having over 30 active sites most days, Dempsey Wood is involved in projects of significant size throughout the year. Having to use heavy machinery on worksites within busy residential areas, often governed by strict consent limits around emission of dust, noise and vibration has constantly been a challenge. Furthermore, maintaining a positive relationship with nearby residents is crucial, with complaints having the potential to cause disruption to projects at least while the investigation takes place.

Moving to a real time reporting system was attractive to Dempsey Wood to ensure safe, comfortable conditions for people, both onsite and in surrounding areas to work and live in, as well as to help mitigate complaints and to support internal compliance monitoring.

The solution provides sensors that monitor environmental parameters of noise, vibration and dust. Data from the sensors once transferred to the Adroit Platform dashboard via Spark Cat-M1 network, is represented visually as real time data with the ability to download .csv files. Alerts and notifications can be received via email, and iOS and Android apps, and APIs are available so data can be used on other platforms or databases.

Additionally, more sensors can be added to monitor different parameters such as sediment in water run-off and weather conditions. Noise data collected by sensors can also derive values to represent average and peak sound levels experienced on the site, to help manage site compliance.

This solution provides great confidence in Dempsey Wood’s control methods to aid management of site compliance, as well as providing accuracy and verification when dealing with complaints.

‘Environmental IoT technology gives Dempsey Wood a good understanding of our site activities from real time data, and this enables us to run a safe and compliant work site for our employees and the wider community.’
