Structures at or near airports must comply with obstacle limitations prescribed by ICAO and the relevant national regulator when they are built or modified, to ensure flight safety is not compromised by any change in the built environment.

Lacle supports airport operators and property developers during the design, construction and commissioning stages by conducting
obstacle assessments and analyses of any new or modified, permanent or temporary structures.
