The Engineering Complex at UNB is comprised of five buildings, all constructed at different times, and physically connected as one. The first building constructed in 1901, was the original Engineering Building, designed in the Romanesque Revival style, followed closely thereafter by the former Gymnasium, converted in 1944 to the Electrical Engineering Build-ing. In 1957, an expansion to the western side of the two original engineering buildings was made. Sir Edmund Head Hall, a five-storey, 13,600 sq.m (140,000 sf) addition was con-structed to the north of the previous mentioned buildings. Gillin Hall was added to the west side of Head Hall in 1989 and the Information Technology Centre was added to the south of Gillin Hall along Windsor Street in 2000.
In April of 2017, UNB requested Murdock & Boyd Architects to come up with a design solution for a new prominent Main Entrance to the Head Hall Engineering Complex, one that celebrates the engineering programs that are delivered at this institution. The space is designed to allow for and promote the collaboration and interaction of students and faculty, provide for additional graduate study areas, larger crush space from the Dineen Auditorium and a space to exhibit and visually celebrate all the disciplines of the world renowned UNB Engineering programs and its graduates.
- In this webinar, you’ll gain insight into the design and manufacturing considerations involved in using glulam in buildings. As one of the oldest mass timber products used in Canada, glulam offers exceptional flexibility and can be incorporated into a wide range of building types—particularly where curvature and expressive geometry are key. Presenters will outline design and manufacturing strategies for creating efficient structures, showing how glulam can be used not just as columns and beams, but as the primary structure in today’s innovative buildings—whether architecturally driven or focused on value and efficiency. They will also cover the availability of glulam products across Canada and explain how to maximize the value of the timber used. Practical tips will be shared to help designers and specifiers take full advantage of glulam’s attributes in a cost-efficient way. Understanding Glulam: The structural and architectural capabilities of mass timber Date: June 5th, 2025 Time: 1 PM Eastern Time Duration: 1 hour Learning Outcomes: Participants will learn the design strategies employed when using curvature and geometry in buildings and gain an understanding of what is possible with expressive architecture. Participants will understand the practical constraints of glulam manufacturing, including how to approach the design and specification of glulam members. Participants will learn how different wood species and strength grades are applied in glulam design, and how to use them efficiently for optimal performance. Participants will understand how geometry, fire ratings, and member layups influence the cost-efficiency and design potential of glulam systems.

This report serves as a practical guide for small to medium-sized enterprises, start-ups, and builders looking to transition into offsite construction. With a specific focus on prefabricated elements and modular systems, it offers actionable guidance for manufacturers considering process expansion or upgrades. Covering critical topics such as business planning, transformational change, financial efficiency, design for manufacturing and assembly (DfMA), and technology integration, the report emphasizes that success in offsite construction depends not only on technical capability, but also on strategic foresight and organizational readiness.
Drawing on lessons from both successful and stalled ventures, the report identifies common pitfalls—including rushed implementation, cultural resistance, and premature technology investment—and outlines a disciplined, step-by-step approach to navigating them. Through key themes such as aligning prefabrication with business goals, managing operational change, optimizing financial strategies, and adopting technology judiciously, the report provides a roadmap for sustainable growth. Its insights advocate for a manufacturing mindset rooted in efficiency and adaptability, helping firms approach offsite construction with confidence, clarity, and resilience.
Mass timber construction offers speed, sustainability, and design flexibility – but it also requires a higher level of coordination than traditional structural systems. Its prefabricated components and tight tolerances call for early planning, clear communication, and a shared understanding across the project team. Ensuring that all partners – including those less familiar with timber construction – are aligned on these unique requirements helps avoid costly delays and, more importantly, positions the team to fully capitalize on the benefits mass timber has to offer.
