## Definition

## What Service Media Means in a Contract

Service Media is a broad, umbrella term found principally in leases, development agreements, and construction contracts. It captures every physical conduit and connected apparatus used to deliver or remove essential utilities, including heat, electricity, gas, water, sewage, air-conditioning, energy, telecommunications, and data. Rather than listing each pipe or cable individually every time a contract needs to refer to building infrastructure, drafters insert this single defined term and rely on it consistently throughout the document.

The concept exists because modern buildings depend on an interconnected web of unseen infrastructure, ducts running through ceilings, cables buried in walls, and pipework threading between floors, and contracts need a clean way to allocate rights and responsibilities over that infrastructure. Without a clear definition, disputes can arise over who may access, repair, or reroute a cable running through a neighboring unit.

## How Service Media Is Defined or Measured

Rather than a technical or measurable quantity, Service Media is defined functionally, by reference to the purpose the media serves rather than its physical form. A typical clause will state that Service Media includes all media for the supply or removal of specified utilities and services, and then extend the definition to cover structures, machinery, and equipment ancillary to those media, such as meters, tanks, switchgear, risers, and plant rooms.

Because the definition is expressed broadly and often ends with a catch-all reference to.
