Senior Associate – Structural Group
November 2018 – Present, Toronto, ON

  • Primarily involved in origin and cause investigations, technical assessment and cost estimation related to repair/remediation strategies for various projects, third-party peer review of design documents and reports, contract documents and contractor submittals related to structural design sufficiency.
  • Conduct failure/deficiency analysis for litigation support to identify the most probable sequence of events leading to the ultimate failure/deficiency.
  • Provision of peer-review of reports, plans and specifications to determine whether they meet applicable statutes, regulations, standards, codes, by-laws and acceptable engineering/construction practices.

Ontario Ministry of Municipal Affairs and Housing
Building Code Advisor – Structural Specialist
November 2015 – October 2018, Toronto, ON

  • Provided specialist structural engineering expertise and advice to the government of Ontario to support the regulatory framework for the construction of buildings. Provision of continuous review and improvement of existing regulations and statutes towards further editions of the Ontario Building Code. Additional contributions in efforts related to:
  • Innovative use of mass timber in tall buildings construction.

WorleyParsons
Senior Structural Engineer
July 2011 – October 2015, Edmonton, AB

  • Responsible for design and analysis of various structures complying with client specifications and the Alberta building code for the Fort Hills oil sand mining project. The total cost of the project is estimated at $15B.
  • Delivered detailed design and analysis of various structures for the primary extraction plant and stamped over 150 drawings, which included piling, concrete foundations and steel structures.
  • Supported the steel fabrication and erection requests for information (RFI) and acted as the single technical point of contact representing my team on issues related to steel fabrication and erection.

Freelance
Structural Engineer (Part-Time)
November 2013 – November 2014, Edmonton, AB

  • Provided structural engineering services to clients. Projects included:
  • Structural assessment of existing house for intended change of use (added loads)
  • Structural design of single-family model house
  • Structural design of Earthbag prototype emergency shelter

Engineering Analysis and Dynamics
Structural Engineer
January 2008 – October 2009, London, ON

  • Responsible for analysis and design of flooring systems, columns, shear walls and pile caps of concrete/precast structures. Designs included consideration of lateral wind and earthquake loads. Design was carried out according to the governing Building Code, in most cases, the Ontario Building Code. ETABS was used for the building analysis; design was conducted using hand calculations and Response 2000. Projects included:
  • Hampton Inn tower, Niagara Falls, Ontario, Canada: 65-storey building
  • Renaissance Hotel Addition, South Tower building, Niagara Falls, Ontario, Canada: 57-storey building
  • Technia Factory, Jedda, Saudi Arabia: Single-storey precast concrete industrial facility with overhead crane
  • Le Monaco Condominium, Georgetown, Ontario, Canada: 4-storey condominium building

Western University
Research/Teaching Assistant
May 2007 – June 2011, London, ON

  • Research project focused on experimental and analytical development of a novel anchor jointed precast shear walls system intended to resist lateral loads in low-to-medium rise buildings.

University of Toronto
Research/Teaching Assistant
September 2004 – January 2007, Toronto, ON

  • Research project focused on the effects of axial prestress on the punching shear resistance of unreinforced slabs subjected to wheel loads. The ultimate objective of the research was to gain code recognition to eliminate the need for reinforcement in the top slab of segmental precast bridges.

HZ Consultant
Structural Engineer
February 2002 – August 2004, Cairo, Egypt
