John Bryson, M.Sc.

John brings over 45 years of consulting structural engineering experience, during which time he has built an extensive and diverse portfolio, including more than 200 high-rise residential buildings throughout British Columbia and the United States; more than 30 high-rise office buildings in British Columbia; more than 120 commercial and shopping centre type buildings; more than 150 wood-framed residential buildings ranging in size from 25 suites to 110 suites per project, and more than 80 seismic upgrading projects.

John Bryson was also responsible for the structural design of several projects in California and Mexico, including several high-rise residential projects in San Diego, California ranging in height from 25-storeys to 50-storeys. John has also made seismic assessments of several buildings for the Canadian Embassy in Tokyo, Seoul and New Delhi.

After graduating from the University of Alberta in 1971, John was employed by Read Jones Christofferson, the largest structural engineering company in Canada, for 25 years (18 years as Principle). John formed BMZ in 1998 and maintains his “hands on” approach for all projects he is involved in, and personally participates in the detailed preliminary structural design concept drawings to be produced by his colleagues.

John is recognized in the construction industry for his interest in creative structural engineering and the emphasis on cost-effective design that he brings to his work. His willingness to seek out innovative solutions has been the difference in making many marginal projects financially viable.


John a. Markulin, M.Eng., P.Eng., Struct.Eng., p.E., S.E.

John Markulin is responsible for delivering innovative structural engineering solutions for the firms’ most notable projects. John brings over 27 years of consulting structural engineering design experience, including tall towers, mixed-use commercial and residential projects, light industrial warehouses, and institutional/public facilities such as ice rinks, sports facilities, social housing and extended health care facilities, hotels, and office buildings and LEED-certified projects utilizing a wide variety of structural materials. John continues to remain involved during all phases of his projects, from the preliminary design consultations phase and throughout all phases to the completion of construction and occupancy.

Prior to joining the BMZ team in 1998, John worked with Weiler Smith Bowers, a Vancouver-based structure engineering company.

John’s emphasis on producing cost effective designs that meet stringent architectural and economic constraints has helped make many projects successful. 

John is a licensed structural engineer in British Columbia, Alberta, California, Washington, and Arizona.


John G. Zickmantel, M.Eng., P.Eng., Struct.Eng., P.E., S.E. 

John Zickmantel has been involved in the industry for over 27 years and is responsible for many of the firm’s projects. John will run the entire job, from the preliminary/conceptual stage, all the way through to the completion of construction. He will scheme the entire structural system of all his projects, including the seismic force resisting system. John has numerous junior and senior engineers who work on his projects and he closely supervises all their work, with close attention being paid to any seismic design being done by others. He also does as much structural design himself as time will permit. John will typically design the most critical and complicated structural elements himself, that require the expertise of an experience structural engineer. Typically, this would entail the seismic design, the column load take-down and design, transfer slabs, or raft slabs in locations where soil conditions require their use. However, one of the most critical aspects of his work is to ensure that the ongoing coordination with the Architect and other consultants does not compromise the integrity of the original structural scheme.

Prior to joining the BMZ team in 1998, John worked closely with John Bryson in his production design group with Read Jones Christofferson. 

John’s experience covers a range of project types and materials. He is particularly valued at BMZ for his ability to meet the demands of the firm’s developer clients for cost-effective design and accelerated schedules. 

John is a licensed structural engineer in British Columbia, Alberta, Newfoundland and Labrador, Nova Scotia, Manitoba, and Washington.
