Delays in concrete curing are one of the main reasons why construction sites fall behind schedule. To avoid delays during the finishing phase, it is essential to begin actively creating optimal curing conditions as soon as the building’s exterior envelope is complete. A new addition to quality assurance measurements on construction sites is the monitoring of indoor air conditions using remotely readable equipment. Today, the client of a construction project or the moisture control plan may also require the monitoring and documentation of conditions during construction. Perhaps most importantly, however, monitoring conditions ensures good drying conditions for the concrete and helps avoid delays.
In practice environmental monitoring This means that equipment is installed on-site to measure indoor air temperature and relative humidity and transmit the data wirelessly to a cloud service. You can view the data on your laptop or via a mobile app. Using the software, the measurement data can be visualized as graphs and weekly averages, among other things.
The monitoring devices are small, and the model we use resembles an electrical junction box. Thanks to advanced batteries, a single device can collect data continuously for over three years, depending on the measurement interval.
Thanks to remote monitoring, tracking site conditions is easy and significantly more reliable than manual measurements. The equipment takes readings at regular intervals, such as every half hour. This provides measurement data 48 times a day from each device, allowing for an accurate assessment of whether site conditions support the drying of structures and the current work phases. In skilled hands, this monitoring enables timely intervention to address problems. Even years later, measurement data and site logs can be used to verify the conditions under which the work was performed.
The biggest challenges on a construction site are signal coverage and damage to sensitive equipment. Signal coverage can be improved by repositioning equipment or installing additional base stations. Damage can be prevented through better placement, labeling, protection, and by informing installers of the equipment’s presence. In practice, however, some equipment loss still occurs.
By monitoring indoor air conditions, we can continuously determine whether the drying conditions at the construction site are adequate and take corrective action as needed. The equipment’s measurement data also shows whether the measures taken have been effective and whether they are appropriately scaled.
