Construction Safety and Phase Planning (CSPP) is a crucial document to have an impact on normal airport operations for any airport construction project. The basic intent of every CSPP is to minimize risk and to ensure that airport operations are not hindered at the time of construction activities taking place on the site. It is important to have such documents readily planned and prepared before initiating any construction activity at the airport. However, the requirements for such documents vary significantly around the world. International Civil Aviation Organization (ICAO) helps to create a mutual understanding of aviation policy, framework, and guidance. There is a lack of data identifying the differences between ICAO and CSPP. This can be challenging in terms of participating in the overseas market for consultancies and engineering firms for the very first time. Eventually, to perform the best practice for CSPP development, a lot of practicing firms find it arduous as there is little data available on understanding the best practice. This paper provides data that discusses and questions the possibility of best practices for CSPP development within the current industry and is further bolstered by case studies, surveys, and other empirical research found in project management research. The paper also confers the key differences present in the current practicing CSPP developments and the requirements published in ICAO states.
