“In large projects, such as commercial buildings, residential complexes, or industrial facilities, service risers are vertical shafts or dedicated spaces used to house various utilities and services. These risers serve as conduits for the distribution of essential services throughout the building. The specific services found in service risers can vary depending on the type of project, its size, and its intended use. Some common services typically found in service risers include:

Electrical Service: Electrical risers contain electrical wiring, cables, and panels that distribute power throughout the building, providing electricity to lights, outlets, equipment, and machinery.

Plumbing and Water Supply: Water risers house water pipes that supply clean water to the building’s various floors and units. These risers also facilitate the flow of wastewater and sewage down to the main sewer lines.

Fire Protection Systems: Service risers often contain components of the building’s fire protection systems, such as fire sprinkler pipes, fire hydrant connections, fire alarm control panels, and fire extinguisher cabinets.

Heating, Ventilation, and Air Conditioning (HVAC): HVAC risers carry pipes and ducts for heating, cooling, and ventilation systems, which help regulate the indoor temperature and air quality throughout the building.

Gas Supply: For buildings that use natural gas for cooking or heating, gas risers house gas pipes that deliver gas to individual units or appliances.

Telecommunication and Data Cables: Service risers may contain telecommunications and data cables, such as fiber-optic cables and Ethernet cables, providing internet, phone, and other communication services to the building’s occupants.

Elevator Shafts: Elevator risers are dedicated shafts that house the elevator equipment, including the elevator car, counterweights, and mechanical components.

Security Systems: Service risers may include components of security systems, such as CCTV cameras, access control systems, and burglar alarms.

Plumbing for Mechanical Equipment: Some large projects may have mechanical rooms on each floor that require plumbing services for equipment such as boilers, chillers, or pumps. These services are often run through risers.

Waste Management Systems: Service risers may contain chutes or pipes that facilitate the disposal of waste from upper floors to a centralized collection point.

It’s important to note that the services found in service risers can vary depending on the building’s design, the local building codes and regulations, and the specific requirements of the project. These risers are crucial for efficiently and safely distributing utilities throughout the building while also providing ease of maintenance and access to the services.”
