Time Efficiency

Real-time data from sensors allows for precise scheduling of subsequent construction activities. If the sensors detect that the concrete has cured faster or slower than expected, the construction schedule can be adjusted accordingly. This reduces delays and keeps the project on track.

By accurately predicting the curing times, project managers can schedule follow-up work more efficiently, ensuring that there are no unnecessary delays. This leads to smoother project timelines and more reliable completion dates.

Reduced Costs

Proper curing is essential to avoid structural failures and rework. By ensuring that the concrete cures correctly the first time, IoT sensors minimise the risk of expensive repairs and rework. This leads to significant cost savings over the course of a project.

Preventing structural issues from the outset saves both time and money. Additionally, by avoiding rework, projects can be completed faster, leading to further cost savings and allowing for quicker handover to clients.
