Sustainable strength: how DC students are reimagining concrete

Capstone projects are an important part of many programs at Durham College (DC), including Civil Engineering Technology, challenging students to apply their knowledge to complex problems while developing skills valued by employers. Through projects that often involve industry partners, students gain experience that supports a strong transition into their careers.

For Civil Engineering Technology students Amena Maududi, Alvaro Reyes and Rouaa Alaalyan, that meant tackling a timely question: how can concrete be made more sustainable? Their capstone project explored the use of coconut coir fibre as an alternative to traditional reinforcement materials, with a focus on improving concrete’s tensile and flexural performance while also reducing environmental impact.

“The problem we were trying to solve is that concrete is strong in compression but weak in tension, which can limit its durability in certain applications,” says Maududi. “We wanted to explore whether coconut coir fibre could improve tensile and flexural performance, while also offering a more sustainable alternative to traditional reinforcement materials.”

The team tested concrete mixes for compressive strength, flexural strength and workability. Samples were prepared at DC’s Shop Lab 5, then cured and tested at the City of Oshawa’s Materials Testing Lab, with additional testing conducted at York University’s Lassonde School of Engineering, with support from Dr. Dan Palermo, Professor and Deputy Provost, Markham Campus.

“Working across different labs taught us the value of collaboration and adaptability,” says Alaalyan. “We learned professional communication and project coordination skills that are essential in engineering practice.”

Their capstone work was guided by Dr. Pourang Ezzatfar, whose mentorship helped the students connect with external partners and refine their approach. “He challenged us to think critically, justify our decisions and continuously improve our work,” says Reyes. “That pushed us to approach the project with a more professional and analytical mindset.”

Maududi says the program played a key role in building both technical and professional confidence. “From the first year, we had opportunities to apply what we learned, work with industry-standard software like AutoCAD and Civil 3D, and strengthen our communication skills. Those experiences have prepared me to enter the workforce with confidence.”

All three students also completed field placements with the City of Oshawa’s Materials Testing Department, where they gained experience in both laboratory and site-based testing. That experience directly informed their capstone work and strengthened their understanding of quality assurance and materials performance in construction.

Looking ahead, Maududi hopes to pursue design-focused roles while continuing to explore sustainable engineering practices. “Capstone showed me how material choices and design decisions affect the environment. I want to contribute to projects that meet technical standards while promoting sustainability,” she says.

For prospective students, she adds that the capstone is one of the most rewarding parts of the program. “It’s a chance to take initiative, think independently, and bring together everything you’ve learned. Teamwork, communication, and problem-solving are key, and the experience is both challenging and memorable.”

The team’s work highlights not only new approaches to sustainable concrete, but also how DC prepares graduates for careers in the civil engineering field. Through applied learning and industry-connected experiences, students develop the skills needed to contribute from day one.

D.G. Biddle visits Whitby campus to celebrate support for DC’s Civil Engineering Technician and Technology programs

Durham College (DC) welcomed local civil engineering and planning services consultancy, D.G. Biddle & Associates Limited, to the Whitby campus in March to celebrate their gift of $50,000.

D.G Biddle’s generous donation allowed the college to purchase a Universal Testing Machine (UTM) for use in the Civil Engineering Technician and Technology programs, greatly enhancing students’ hands-on learning experience.

During the visit, first-year Civil Engineering Technology students, James Gallagher-Conejo and Zain Khan, demonstrated a double shear test on aluminum and copper.

“A UTM can be used to perform tensile, compression, shear, double shear, hardness, and flexure tests on materials like steel, aluminum, brass and copper,” explained Myla Minelli, Program Coordinator. “These tests allow students to understand how materials behave under different loading and how they are applied in real-world construction scenarios.”

After the demonstration, guests visited the D.G. Biddle & Associates Limited Computer-Aided Design Lab, named in recognition of the firm’s generous support for capital equipment at DC – the college’s top fundraising priority at this time.

“We’re proud to support students at Durham College,” said Michael Carswell, Managing Principal, D.G. Biddle & Associates. “We like to hire local talent and believe that supporting DC’s programs is a great way to contribute to the education of those seeking satisfying and rewarding careers in civil engineering.”

In 2024, D.G. Biddle & Associates Limited marked the company’s 50th anniversary. Located in Oshawa, their team includes technicians, clerical, and field personnel providing civil, structural, mechanical, electrical engineering and planning services to both private and public clients. Over the years, D.G. Biddle has built a strong partnership with the college, offering co-op and field placements to students as well as hiring DC grads.

“I’d like to thank Michael and the team at D.G. Biddle for seeing the value of DC’s civil engineering tech programs,” said Ariel Sully, Associate Vice President, Advancement and Alumni Relations. “This investment in our programs and students ensures our students have access to the equipment and opportunities they need to acquire the experience employers are looking for.”

 


DC engineering grads can leverage their learning with new Queen’s University Diploma-to-Degree Pathway

Durham College’s (DC) engineering technology graduates can get a head start on their degree thanks to a new pathway agreement with Queen’s University.

Students who graduate from DC with one of our advanced diplomas in Engineering Technology can now transfer into an upper year of the civil, mining, mechanical, or chemical degree programs offered by Smith Engineering at Queen’s.

“We are thrilled about the strong partnership between DC and Queen’s University. This is a testament to our commitment to providing students with the best possible educational experience,” said Kara Woods, Associate Dean of the Faculty of Science, Engineering and Technology. “By integrating practical learning from DC with the rigorous academic framework at Queen’s, we are empowering students to transition smoothly from diploma to degree.”

One such student is Mitch Connelly, a 2021 graduate of DC’s Civil Engineering Technology program who is part of the pathway’s inaugural cohort that began their studies in September. After years of working in the engineering field, he decided to return to school to upgrade his skills, and his timing was perfect.

“It’s a lot cheaper than doing a full undergraduate degree straight from high school, and college is also more practical. I think employers recognize that,” he said of the pathway. “It’s better to go this route. You get a better education and more connections.”

Mitch’s post-DC success and his pursuit of a degree at Queen’s serve as an example to today’s students, according to Civil Engineering Technology program coordinator Myla Minelli.

“Mitch exemplifies the dedication, hard work, and determination that we strive to instill in all our students,” she said.

More DC students are set to take advantage of the new pathway, with seven beginning the required online preparatory courses this fall before attending a full semester of foundational classes next summer. They will then enter their respective programs at Queen’s in September of 2025.

The Smith Engineering Bridge pathway is funded by the Ontario Council on Articulation and Transfer (ONCAT).
