Engineering students use georadar to study tennis courts

Third year civil engineering students saheb BirgiSaul Halprenprince Giciro and John Akinpelu faced a figurative crossroads for their final civil engineering project.

The quartet, group 08CF, had chosen the Elmridge Tennis club in Gloucester for their project. Their aim was to analyze the court conditions then develop a permanent repair plan for the club.

The group made their first site visit on Friday October 15, 2021 and on Saturday November 6, 2021 they completed their work on the site. However, the band felt like did not have done enough.

“We wondered what more we could do, and our teacher mentioned [ground-penetrating radar]”, Saheb says Birgi in a Zoom meeting. So, the whole team researched and we tried to see if we could get GPR equipment.

“A ground-penetrating radar instrument can measure the dimensions, depth and thickness of underground targets,” he said. This is done by sending radio waves into the ground at a certain speed and then recording the time it takes to return to the receiver. This number is then divided by two to give us a depth of field what’s underneath.”

The group was eager to try the idea.

“It was a struggle” he said. “We wrote an email, sent it to the course coordinator and our teacher. They sent it to someone above them and it took a while for a response.

Unfortunately, they learned that the college had no money for them.

“It was eventually resolved and they said ‘No. We don’t have a budget. If you want to You can do it yourself.’ They were strongly to advise us not to do it,” he said. “But once we actually has it’s done and I got the equipment, they congratulated us.

The students decided to contact Geofed Ltdan Ottawa-based company that transformed them for Sensors & Software Inc., a Toronto-based company. the two parties reached an agreement allowing students to borrow the equequipment.

Birgi and Halpren traveled to Toronto on Friday, November 26, 2021. They signed a waiver, picked up the GPR, and returned to Ottawa. The group carried out the site visits during this weekend, before brought the equipment back on Monday.

“We did like 20 hours of driving in three or four days,” said Birgi.

The group’s former teacher, Federico Fernandez, also played an important role in the realization of the project.

“He was ready to sign just in case something went wrong,” said Halpren. “If we break the equipment, he would have you have to pay for it. He took a risk doing that.

Yeah he actually inscribed his name,” said Birgi. “We were like ‘who is going to be responsible if say we drive back and enter a accident?’ and he put in fact his name down.

Despite the inconveniences, Birgi says they would do it again if they had to.

Yes, one hundred percent. It was such a great learning experience,” he said. “I feel like we never would have known what a GPR system was without this project and doing everything we could to get it, learn it and use it.

“The use of GPR equipment allowed us to observe the underground parameters on which the Elmridge Park tennis club built its courts. It confirmed that there were anomalies however, for the most part, the Deep underground construction was very well constructed with minor deviations and overall using it gave us another set of data to compare which makes the report more soundproof and fully accurate,” he said. .

The total value of the equipment lent by Sensors and Software Inc. was $48,390.

At the time of writing, gThe conclusions and recommendations of the 08CF group project have not yet been finalized.
