INTERNATIONAL WOMEN IN ENGINEERING DAY – Carmen Stan
At Onnec, we’re proud to celebrate International Women in Engineering Day by spotlighting the incredible talent and contributions of our team. Today, we’re featuring Carmen Stan, a Senior BIM Engineer at Onnec. Carmen plays a pivotal role in bringing Data Centre projects to life through precision, innovation, and collaboration.
Before diving into Carmen’s journey, let’s take a closer look at the world of BIM and why it matters.
WHAT IS BIM AND WHY IS IT CRITICAL?
BIM (Building Information Modelling) is more than just a 3D modelling tool. It’s a digital process that allows engineers, designers, and construction professionals to create and manage data across the lifecycle of a built asset. From early design concepts to construction and beyond, BIM ensures everyone involved is working from the same, most up-to-date information.
At Onnec, BIM helps us deliver complex infrastructure projects – such as high-performance Data Centres – with greater accuracy, speed, and sustainability. It’s especially important in fast-paced environments where coordination between disciplines, reduction of waste, and minimised risk are essential.
MEET CARMEN STAN, SENIOR BIM ENGINEER AT ONNEC

How long have you been working in engineering, and what led you to BIM?
Carmen – I’ve been in the engineering field for over 15 years. I started my career in Architecture after completing my MSc in Telecommunications at the University of Bristol. My journey into BIM began around 10 years ago when I started working on Telecom designs for Data Centres. I’ve always been fascinated by the ability to use data to identify patterns, improve collaboration and solve coordination challenges. BIM brings all of that together in such a powerful way.
What does a typical day look like for you as a Senior BIM Engineer at Onnec?
C – On a typical day, I might be coordinating 3D models, running clash detections, or reviewing designs and drawings to ensure alignment with client requirements and local regulations. One of the parts I enjoy most is collaborating with colleagues across different disciplines to resolve issues and maintain a consistent, high-quality digital model. I really enjoy spotting patterns and resolving clashes – it’s like solving a giant puzzle. Since joining Onnec, I’ve transitioned from working mainly on design-stage deliverables to focusing on as-built models. This feels like a natural progression. I take pride in consistently applying and upholding BIM standards throughout the project lifecycle.
What has been the most exciting or rewarding project you’ve worked on at Onnec?
C – One of the highlights for me was working on a challenging multi-site hyperscale DC project, where we managed to collaborate and update our model to be implemented in the federated BIM model, thus significantly reducing design conflicts and saved time on site, demonstrating just how impactful BIM can be. This experience, along with obtaining my BIM certification, has been especially meaningful – it’s a reflection of how far I’ve come in this field and continues to motivate me.
What advice would you give to women considering a career in engineering or BIM?
C – “If you can’t see one, be one.” That quote really resonates with me, especially in a field like engineering where women are still under-represented. If you’re curious, determined, and enjoy problem-solving, this field has so much to offer. Find mentors, keep learning, and don’t be afraid to speak up. You bring a unique perspective that is both valuable and needed. I’ve had the privilege of mentoring through Women in BIM and have taken part in two women-focused events since joining Onnec. It’s been incredibly rewarding, and I feel genuinely supported. It’s great to bring a female perspective into a highly male-dominated area, and I hope more women feel empowered to do the same.
SUPPORTING WOMEN IN ENGINEERING THROUGH ACTION
Carmen is just one of the many women driving innovation across Onnec. and We’re committed to supporting more female talent in engineering and tech. Through our Women at Onnec ERG and partnerships with organisations like Women of the Future and Women in Construction, we’re on a mission to inspire, develop, and retain female talent across the tech space.
This International Women in Engineering Day, we’re proud to celebrate the incredible work of Carmen and all the women shaping Onnec’s success.
