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• Current TAMS documents out of date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

TECHNICAL SPECIFICATIONS
(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)

(short term)
• Initial 12-18 month soft rollout
– Apply documents to a design and construction project– Apply documents to a design and construction project
• Third party engaged
• Assessment of documentation in consultation with users
• Close consultation with consultants and contractors to streamline procedures
• Subsequent brief review, with amendments as necessary
IMPLEMENTATION
(18 months onwards)
• New documentation (TRIS and TRITS) is to be • New documentation (TRIS and TRITS) is to be used for future road infrastructure works
• 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)
