In this episode, we talk to three people who are involved in seismic upgrades to a Heritage Designated World Recognizable Work of Architecture, the Museum of Anthropology (MOA) in Canada. They are Nick Milkovich, Principal at Nick Milkovich Architects Inc. Who is also the principal architect for the upgrade, Aletha Utimati, Project Manager at The University of British Columbia and for the Great Hall renewal project, and 5013 and Eric Karsh, a structural engineer and principal at Equilibrium Consulting Inc and a leader in timber engineering and construction. They talk about some of the seismic upgrades planned at the Museum of Anthropology.
Here Are Some of the Questions We Ask Our Guests:
- Tell us what your job will entail in the process?
- Why is the University of British Columbia undertaking this project?
- Tell us about the experience of working with the late Arthur Erickson, what it meant to you, and how it affects your perspective on this project?
- Tell us more about using base isolation technology and vertical glass upgrades and its challenges.
- What are some of the challenges of doing construction beside a working museum?
- How will the differential seismic movement between the Great Hall and the rest of the museum influence the construction process?
- How do they plan to protect the massive wooden carvings and poles that reside in the Great Hall during construction?
- What does it take to become an expert on a specific design process or material for a structural engineering professional?
Here Are Some of the Key Points Discussed About the Seismic Upgrades To the Museum of Anthropology:
- The Great Hall has a tall and slender design and is wrapped in glass, which makes it susceptible to seismic forces. The structure needs to be preserved while bringing it up to code, without changing the architecture.
- The seismic upgrades need to be done on the Great Hall as it is one of the high-risk areas on the campus. This was found through a comprehensive evaluation of seismic risk across all buildings, utilities, and assets on the campus. The seismic upgrades are not only being done for human safety but to also preserve the museum’s invaluable collection if a seismic event had to happen.
- Arthur Erickson’s office was an interesting place and felt like a continuation of school. Anyone could come up with ideas to be discussed, debated, and implemented. The concept behind the museum was based on a photograph that Arthur saw villages on Anthony Island which were all close to the beach. The movement through the museum represents the movement from the forest, across the beach, and ending by the water. Arthur was interested in the proportional experiences that people would have when walking through the museum.
- Because of the museum’s heritage properties, traditional seismic upgrades are not an option. The introduction of additional elements or braces could not be hidden anywhere, and the structure is an integral part of the architecture. This means that anything you do to the structure impacts the original work, which is something that was committed to avoid.
- Base isolation means to disconnect the building from the ground and put it on a bed of jello which will significantly reduce the seismic loads on the structure. This however was not enough for the great hall to not get structural damage and the glass on the building would also suffer damage in a seismic event. This means that the entire building is needing to be rebuilt to mirror the old building but will structurally meet the code. The original glass was not detailed to accommodate much movement. The rebuild allowed redesigning the interface between the glass panels and the structure to ensure the anticipated seismic movements would not likely cause any damage to the glass.
- To use base isolation on an existing structure, you need to create a crawl space beneath the foundations of the structure, one column at a time. Each column will need to be cut between the ground plane and the footing to introduce an isolator, and then build a new floor slab to tie all the columns and isolators together.
- The project needs to minimize the impact it will have on the rest of the museum. This is done by a lot of collaboration between all the parties involved. Closing the great hall will have a big impact on the museum so the schedule for this project is made up to take as little time as possible. Ongoing vibration monitoring is in place for the rest of the museum to ensure that the artifacts will be kept safe during the seismic upgrades reconstruction of the great hall. The security is also being highly monitored due to the value of the artifacts that need to be moved or relocated. A temporary access road has been constructed to give easy access to the great hall during the seismic upgrades construction process and will be removed once the project is completed.
- All the wooden poles and carvings had to be moved to another gallery to ensure their safety. A moving company that specializes in moving artifacts and delicate objects was used to move the artifacts and leave them lying horizontally while the reconstruction is done. This allows the museum to further study them and perform maintenance that could not be done before. Upgraded mounts need to be made for the poles and carvings to accommodate the extra movement that is being designed into the structure.
- There will be differential movement between the great hall, the rest of the building, and the surrounding grate. Connectors need to be designed that have the flexibility to withstand the differential movement of a severe earthquake, which will be around 1 foot 2 inches of movement on all axes. These large joints are needed because base isolation disconnects the building from the foundation, which makes the building move slower, but a greater distance than the foundation in a seismic event.
- If you know that you love a certain topic or want to specialize in something, you should take the opportunity to get the basics through your studies and in an environment where you learn while on the job. Develop your expertise one project at a time, over a long time. Applying innovation in your projects will let you accumulate a lot of knowledge over time.

About Our Guests:
Nick Milkovich was born and educated in Vancouver. The day after graduating from the University of British Columbia with a Bachelor of Architecture degree in 1968, he joined the firm of Erickson/Massey. He continued to work for Arthur Erickson Architects from its origins in 1972, becoming an Associate in 1979 and Director of Design in 1987. While heading the firm’s custom private residential work, Nick was also a member of the design team for the award-winning Museum of Anthropology at UBC and the Law Courts in downtown Vancouver.
After 6 years in the profession, Nick felt ready to apply to register with AIBC, which he received in 1975. Nick was elevated to fellowship of the Royal Architectural Institute of Canada in 1997.
Nick established Nick Milkovich Architects in 1991. Since its inception, the firm has created a broad portfolio including: large planning and urban design projects, large-scale public buildings, small- and medium-scale residential developments, and single-family residences, in North America and Asia.
