COLOMBO - CTBUH Sri Lanka was part of the CTBUH Global Walking Tours for the first time. The tour began at the construction site of a high-rise project called The One Colombo, formerly known as Krrish Square.

Despite an enthusiastic response and many willing participants, due to practical restraints on the construction site, the tour was only available to 25 participants, and priority was given to attendees on a first come, first served basis. Attendees for the tour included Chairman of Sri Lanka Institute of Architects, Senior Officials from organizations such as the Urban Development Authority, Ministry of Megapolis (Metro Colombo Urban Development Project) and a mix of senior and junior architects and engineers.
