AGENDA

• Review of ACT Documentation

– Current documents, reasoning for review, principles, process

New documentation• New documentation

– Structure, content

• Changes

– Standards, Specifications, Contractual

• Access to documents

• Implementation

– Short term, implementation, ongoing management

CURRENT DOCUMENTATION

• Design Standards (DS)

• Standard Specifications (SS)• Standard Specifications (SS)

• Omnibus of trunk and development infrastructure

• Very prescriptive in some areas ambiguous in others

REASONING FOR REVIEW

• Current TAMS documents out of date

• General comments from industry: TAMS • General comments from industry: TAMS documents need revision

• Responsibility to align design to Austroads

• Consistency in construction methodology

• ARRB engaged to undertake review

PRINCIPLES

• Consistency in design and construction across all trunk road infrastructure in ACTacross all trunk road infrastructure in ACT

• Consistency with national ‘best practice’ and other road authorities, especially NSW

• Align with Austroads Guides

• Align with current TAMs road hierarchy

• Preserve ACT specific requirements

REVIEW PROCESS• Review of current standards (DS) and

specifications (SS)

• Comparison with Austroads Guides• Comparison with Austroads Guides

• Comparison with state practices and specifications

• Consultation with specialists and industry

– Discussion sessions, workshops

NEW DOCUMENTATION• Reflect TAMS dual role as road authority

and ‘local council’

• Move away from Omnibus � separate• Move away from Omnibus � separate

– major roads infrastructure and

– land-use development infrastructure

• Roads scope: sub-arterial and higher (i.e. trunk roads)

NEW DOCUMENTATION

• Change from standalone documents to supplementary format

• Supplementary documents to be read in • Supplementary documents to be read in conjunction with overarching documents

• Content based on existing standards and specifications, amended/updated as needed

• Trunk Roads and Development treated separately

Specific ACT information



(TRITS)

• Prescribe detailed practices and requirements for construction and installation of road infrastructure in ACT

• Aligned with QA and construction specifications from NSW Roads and Maritime Services (RMS - formerly RTA) wherever feasible

Alignment with RMS Specs

• RMS specifications adopted wherever feasible

TRITS Documents

• TRITS Documents refer to relevant RMS specs

• RMS specs edited where necessary to include ACT requirements

CHANGESSTANDARDS

• Design process

– Focus on design outcomes and holistic approach

Less on prescriptive methods on how to achieve – Less on prescriptive methods on how to achieve objectives/intentions

» Move away from a ‘one size fits all’ solution

– Consistency in design objectives/intentions

– Provide opportunity for designers to provide innovative solutions

• Relationships

– Improve design collaboration between the principal and designers

CHANGESSPECIFICATIONS

• Construction Process

– Focus change from prescriptive construction to achieving quality of final productsquality of final products

– Improve site safety

– Terminology

• Relationships

– Reinforce the responsibilities of Superintendents and Contractors

– Foster a more collaborative effort between Superintendents and Contractors

CHANGES

CONTRACTURAL CHANGES

– Adoption of RMS quality management system based on works amountworks amount

• Q2 - <$0.2M and not requiring prequalification

• Q3 – QA contracts requiring prequalification or registration

• Q4 – QA contracts for major contracts $0.2M-$1.0M

• Q6 – QA contracts for major contracts >$1.0M

– Pay item changes

CHANGES

CONTRACTURAL CHANGES (cont)

– Changed responsibilities

• Introduction of witness pointing (superintendent and contractor)

• Improved quality management documentation (superintendent and contractor)

• Improved construction documentation (ITPs – Contractor)

• Improved site safety management (TTM – superintendent and contractor)

• Interface between trunk road works and development infrastructure works is crucial

• DV306 referencing current TAMS Design Standards (DS) and Standard Specifications (SS) shall hold for development works only

IMPLEMENTATION

(18 months onwards)

• TRIS to supersede existing TAMS Design Standards • TRIS to supersede existing TAMS Design Standards (DS) for trunk road work projects only

• TRITS to supersede existing TAMS Standard Specifications (SS) for trunk road work projects

only

• Introduce use of Industry Technical Notes (ITN)

ONGOING MANAGEMENT• Ongoing collaboration with Consultants and

Contractors/Suppliers

• Review of new Austroads Guides as they are made available

– As a signatory will principally adopt new Austroads, supplementaries will be developed in time

• Review of new RMS Specifications as they are made available

• Review of documents on a two (2) year basis

• Introduction of Industry Technical Notes (ITN)

• Development of industry alerts for ITN and document changes (new editions and revisions)
