Although the Historic Peninsula of old Istanbul was added to the UNESCO World Heritage List in 1985, no documentation of this important area has yet been carried out. In 2006 the Istanbul Greater Municipality's Directory of the Protection of Historical Environment initiated the "Historical Peninsula project", which comprises a project area of 1500 ha and approximately 48,000 buildings in crowded and frequently narrow streets. Therefore, BIMTAS, a company of the Greater Municipality of Istanbul, started the documentation of all buildings in the area of the Historic Peninsula by terrestrial laser scanning in the same year. It was a challenge to build up a new production environment with new high-end technology to fulfil the requirements of this project in a very short time frame of two years. This paper describes the entire production environment for documentation of all buildings, detailing the frequent adaptation of production required through learning on the job. Although the data acquisition and mapping environment was established on the job during production, it was always essential to optimise the technical solutions in order to meet the quality requirements for the generated data and for the deadlines of data delivery. Only 80ha of 1500ha could be completed by static scanning during six month, requiring the change from static to mobile terrestrial laser scanning due to the increased speed of scanning, whereby the remaining major area could be scanned within three months by the mobile method.
