Mr. Mohammad Ayub, PE, SE Principal Structural Engineer Mimar Architects and Engineers Former, Director, Office of Engineering, OSHA, US Department of Engineering Education: MS in Civil Engineering with major in Structural Engineering; George Washington University, Washington DC, BS in Civil Engineering, Birla Institute of Technology, Mesra, Bihar Licenses: Registered as Civil engineer in District of Columbia, MD, VA and PA; Registered as civil and structural engineer in California 1989-2020 For major construction incidents resulting in multiple fatalities of construction workers and other employees, OSHA would request National Bureau of Standards (now National Institute of Standards and Technology) for causal determination as OSHA lacked in-house capability. In 1989, OSHA established its own Office of Construction and Engineering to undertake such tasks. Mr. Ayub joined OSHA in 1989 in the furtherance of this task, and soon became Director of the Office of Engineering Services in 1992 until his retirement on January 3, 2020. During his tenure in OSHA, he conducted forensic investigations of 69 catastrophic construction incidents pertaining to steel structures, concrete structures, parking garages, antenna towers, tunnels, excavation stability failures, mast climbing platform failures, formwork failures, scaffold failures, fall protection failures, shoring and re-shoring failures, etc. see appendix B. 2020-current Principal structural engineer in charge of various projects, i.e., 1. WMATA Maintenance Building, Parking Garage, Pedestrian Bridge and ramp leading to the parking garage in Bladensburg, DC 2. Charles Carroll Community Center, Westminster, MD 3. Readiness Center, Williamstown, PA 4. Maintenance Building, Administration Building, Canopies for Trucks, Fuel Stations, Pump Building, etc. at Kingsville, MD 5. VA Medical Center, Richmond, VA repair and restoration of concrete at the first floor structural slab. 6. Maryland Transportation Authority Truck Maintenance Building and Administrative Building at Raphael Road, Kingsville, MD, Experience: OSHA published Mr. Ayub’s findings on the public facing web page resulting in a heightened awareness of construction safety among construction stakeholders. It is believed that the findings and conclusions of his reports have ensued a higher degree of attentiveness towards safety, and could have resulted in lower fatalities in construction industry. Notable among them are the following. The reports are in public domain. 1. 2019 Hard Rock Hotel collapse in New Orleans, LA on October 12, 2019 killing three employees. 2. 2018 FIU pedestrian bridge incident that killed five motorists and one employee 3. 2015 mast climbing incident at Raleigh, NC that killed three employees 4. 2015 collapse of two pedestrian bridge in Raleigh, NC killing two employees 5. 2014 plant collapse in Omaha, NE that killed two employees; 6. 2014 Ringling Bros. and Barnum & Bailey performance incident in Providence, RI. 7. 2013 parking garage collapse in Doral, FL that killed four employees; 8. 2009 mast climbing platform collapse in Austin, TX that killed three employees; 9. 2008 crane collapse in NYC, NY that resulted in six fatalities; 10. 2006 Stripping platform collapse in Jacksonville, FL that resulted in two fatalities. 11. 2003 parking garage collapse Atlantic City, NJ that killed four employees. 12. 1998 Antenna tower collapse in Raymond, MS that killed three employees 13. 1990 collapse of tower crane in San Francisco, CA that killed four employees. Experts witness: Mr. Ayub appeared as an expert witness in eight structural catastrophic incident cases, all of which resulted in favorable decisions. The cases involved structural concrete and steel framings, parking concrete garages, cell and antenna towers.
