I have been in the building industry since 1978 after graduating with an A.S. in Building Construction Technology ('76) and a B.S. in Building Construction Management ('78), both degrees from Spring Garden College, Philadelphia, PA., USA. I have been a scheduler for 31 years working on heavy construction projects, hospitals, educational facilities, stadiums, research laboratories as well as pharmaceutical manufacturing facilities. I also have worked on historic renovations, parking garages - precast and cast-in-place and bridge construction. I have performed delay analysis and provided best practices to project teams from a scheduling / change management perspective. I have reviewed schedules prepared by others for completeness including critical path review and duration assesment. I have been involved in developing RFP schedules to "win" projects which included reviewing drawings and preparing the construction schedule to meet key milestone dates. Duration development was based on production rates gathered over time as well as input from key team members.
