Brian founded Isherwood Geostructural Engineers (formerly Brian Isherwood and Associates) in 1972 and has since made a signification impact on the excavation and underground industry in Canada. For over 40 years, Brian has been involved in the design of all types of foundations, the design and supervision of temporary works for excavations, shafts, and tunnels, and numerous innovative projects requiring a high degree of expertise and monitoring control.

Brian has pioneered the development and improvement of multiple new techniques in the geostructural field and was instrumental in the advancement of soil anchors in Toronto at a time when internal bracing and rock anchors were seen as the primary systems of support. Brian also introduced inclinometer monitoring to support the observational method of excavation support design, and as a result, his work became known for its reliability, quality, and for his dedication to public safety.

Brian earned his Bachelor of Science in Civil Engineering at The University of Birmingham in England in 1956. Brian is a fellow of the Canadian Society for Civil Engineering, a member of the Institution of Civil Engineers of Britain, the Canadian Geotechnical Society, the Tunneling Association of Canada, and the Deep Foundations Institute. In 2015 Brian won the Ontario Professional Engineering Award Engineering Medal for Engineering Excellence: A Career Driven by Creativity and Safety.

Nadir joined Brian Isherwood in 1987 as the firm’s first full-time employee and never left.

Nadir has been involved in the analysis, design, review, field inspection, and monitoring of over 1500 structures across Canada and in the US, Mexico, and the Caribbean. He is actively involved in the improvement of in-situ soil reinforcing techniques and works closely with local contractors and developers to advance soil-nailed, micropile, and ground-improvement design. He is a major proponent of the Observational Method, precision geotechnical instrumentation and monitoring, and the prediction of earth and building movements related to excavations (including finite element analysis modelling). A couple of Nadir’s most memorable projects include the Princess of Wales Theatre, the Tunnel Boring Machine (TBM) Rescue Shaft, Pier 27, and the Sir Adam Beck Tunnel Cofferdam.

Nadir was born in Amman, Jordan, and grew up in London, Ontario. He completed his Master’s thesis on Statistical Modeling of Bridge Loading from the University of Western Ontario. He is a proud member of ten professional associations including the Deep Foundations Institute, the Professional Engineers Ontario, the ADSC International Association of Foundation Drilling, the International Society for Micropiles, the Tunneling Association of Canada, and WPO – World Presidents Organization. Nadir is also the President of Monir Precision Monitoring.

Nadir’s personal interests vary widely and include gastronomy, performance in orchestras and chamber music ensembles, travel, languages, reading, collecting automotive art, and any learning opportunities with social content.
