The Challenge

A client needed to verify whether the existing rooftop slabs and plinths could safely support new and heavier mechanical equipment as part of an upcoming cooling tower replacement at a mall. The assessment had to be carried out accurately and without any disruptive hacking or coring since there was multiple cooling towers involved and the mall operating as usual.

Our Approach & Result

We conducted a non-destructive structural assessment on the rooftop with Xradar™ enhanced concrete scanning. The scope covered reinforcement mapping on 8 existing plinths and 4 slab areas associated with 2 cooling towers.

The scanning works were completed in less than one hour, with all reinforcement layouts, spacing, estimated bar sizes, and slab thickness data captured on site. After the scan, the findings were compiled into a clear and actionable report, allowing the client and engineers to proceed with structural checks and load verification without delay.

At a mall in Kuala Lumpur, the upgrading works starts only after confirming the structural capacity of rooftop slabs and plinths before replacing existing cooling towers with new units.

Using Xradar™ concrete scanning, our team mapped the internal reinforcement of each plinth and slab non-destructively, identifying rebar arrangements, spacing, estimated diameters, and slab thickness without disturbing the structure. This data was critical in supporting structural analysis, ensuring the proposed cooling tower configuration could be installed safely.

The entire scanning process was completed within an hour, and the report was delivered after. This rapid turnaround helped the project team avoid unnecessary downtime, eliminate guesswork, and move forward with confidence.
