Infrastructure sharing can include telecoms cables, power transmission, water aqueducts among others. 

In some cases existing buildings or facilities may be linked to the infrastructure investment. By commercializing these assets, government addresses the challenge of disused or underused assets and creates new revenue streams at the same time.

Infrastructure can be considered in a holistic manner, mandating a developer to deliver a larger investment program including commercial, economic, and social assets.

Infrastructure projects can attract additional revenues through retail services, provided in, above, under, or around the infrastructure facility, e.g. convenience stores, shops, banking services and floating or rooftop solar. 

Vehicle Services provides opportunities for commercial services to the transport entities, such as petrol stations, mechanics, truck/bus parking, e-vehicle, charging stations, air-side services or ship maintenance.

Cargo handling, warehousing, chillers or dry port can provide opportunities for more or new commercial activities creating additional revenue streams. 

Private investment has been used to develop various educational facilities and services or university housing. 

Private investment is often used to deliver specialist services e.g. clinics, imaging, consultants, pharmacy or dental, but as always care needs to be taken to ensure that public services remain the core focus of the project.  Facility-based projects involve the project company providing construction, maintenance, and operation of a hospital or clinic , but not delivery of clinical services. In clinical projects, the project company delivers all services, including the supply of infrastructure and clinical services.

Hotels, restaurants, cafes, catering, and other hospitality and tourism facilities can bring significant revenues for infrastructure. These commercial activities are particularly profitable when located near or associated with locations or facilities that attract crowds.

The space above, below, and around the infrastructure can be used for commercial parking facilities, to earn new revenues and to address congestion.
