Assessments of crowd flows and security arrangements have been done for a number of the temporary venues, including Lords cricket ground where archery will take place and the Wimbledon tennis centre.
Spectators would still have to queue for events which Beca had assumed in its modelling would be sold out.
Kerr said the crowd modelling was a niche business for Beca which is a multidisciplinary technical consultancy with 2500 staff based in offices around the Asia-Pacific region.
The company was involved in crowd modelling in Wellington and Dunedin for last year's Rugby World Cup.
Kerr said he was called in as a consultant after the opening night debacle when crowds at Auckland's waterfront overwhelmed transport and public areas.
Other projects in New Zealand have included the Volvo Ocean Race and work modelling crowd behaviour at Auckland Airport and Wellington Zoo.
