for Austroads and its membersfor Austroads and its members Engaged by Austroads to produce this Guide

Need for Guide Major expenditure by Austroads

members on tunnels Lack of an agreed national technical Lack of an agreed national technical

standard Provide a source of information based

on current knowledgeg

Need for Guide - Issues Uncertain structural design standards Questionable geometric safety standards Poor attention to detail (e.g. leaks)Poor attention to detail (e.g. leaks) High maintenance requirements

High variability in safety standards and High variability in safety standards and systems (e.g. spacing of escape doors)

bl l Variable environmental requirements Incorrect volumetric land acquisition

Purpose of the Guide Provide high level guidance to those making

decisions in the planning, design, operation anddecisions in the planning, design, operation and maintenance of new road tunnels in Australia & NZ.

To be used by-Engineers and technical specialists in tunnel technology Engineers and technical specialists in tunnel technology working on the planning, design and operation of road tunnels

Proponents of road tunnel solutions Proponents of road tunnel solutions Senior decision makers (in an overview role) Regulators

Users of this Guide will be able to determine standards for road tunnel design and operation acceptable to Austroads membersacceptable to Austroads members.

Overall Structure of the Guide

The Guide is in three parts:e Gu de s t ee pa ts Part 1: Introduction to Road Tunnels Part 2: Planning, Design and

Commissioningg Part 3: Operation and Maintenance

Part 1: Introduction to Road Tunnels - Scope Provides overview of requirements . . Details in the

other two partsother two parts

Gives guidance on the planning process to ensure h ll f h f ff h dthat all of the necessary factors affecting the design,

construction, maintenance and operation of the tunnel are consideredtunnel are considered

Covers those matters that have a significant impact th t t i l i f t l l tion the strategic planning of a tunnel solution . . .

Part 1: Scope (cont.) Emphasis placed on risk analysis and management

Introduces process to establish the Fire Safety requirementsrequirements

Discusses the effects of different construction methods, operational factors and maintenance needs that affect the details of the tunnel dimensions, equipment and facilities requiredequipment and facilities required.

Part 2: Planning, Design and g, gCommissioning - Scope Sets out Austroads expectations for

appropriate design Discusses expected approach to the design of

the elements of the tunnel project . . and defines/refers to acceptable standards

This document is intended to establish the benchmark for tunnel planning and design inbenchmark for tunnel planning and design in Australia and New Zealand

Part 2 - Scope This Part does not deal with the

refurbishment of existing tunnels nor therefurbishment of existing tunnels nor the retro-fitting of components to existing tunnelstunnels

Describes the commissioning phase

Tunnels are evolving and therefore this is not intended to be an exhaustive treatment ofintended to be an exhaustive treatment of road tunnels.

Part 3: Operation and pMaintenance - Scope Sets out operational requirements of the systems

described in detail in Parts 1 and 2described in detail in Parts 1 and 2

Describes the protocols required for interaction and di ti f th i th iti hcoordination of the various authorities who are

stakeholders in the operation of the tunnel

Sets the performance standards for the operation and maintenance of the facility as well as providing guidelines for operation of the various systemsguidelines for operation of the various systemsincluding the manuals and operating procedures required.
