2. PROCESS

2.1. General

The design and construction of Lecture Theatres and Teaching Spaces with integrated technology requires a coordinated and collaborative approach from the entire project team. The primary objective of the project team is to achieve the best possible arrangement of architectural building elements, teaching facilities and technology so that both the teaching and learning experience is enhanced.

The technology solution for each room or space can substantially impact the room size, shape, construction and other building elements. Therefore it is critical to consider the audio visual solution during the early feasibility stage of the project.

This document details the requirements for the provision of audio visual and video conferencing systems for a set of standard room types. These room types will be applied to all new buildings and refurbishments of existing spaces.

The design guidelines will be used by Project Managers, Architects, Contractors and other stakeholders involved in the construction and refurbishment of Lecture Theatres and Teaching Spaces.
