1. Introductions. This WORKSHOP is designed to advise those of you who have not used AUS-SPEC before of the benefits of using a uniform set of contract documents and specifications in Local Government. 4
Introductions Bill Woodcock has been in the Local Government Engineering Industry for 35 years. In that time he has worked in positions including Director of Works and Services and Assistant General Manager, Technical Services. As co-author of the AUS-SPEC series he is more than qualified to advise on the best ways to obtain value from the AUS-SPEC series. 5
Introductions The Institute of Public Works Engineering Australia (IPWEA) • is a professional organisation providing member services and advocacy for those involved in and delivering public works and engineering services to the community. One service is to provide the lead in Asset Management, Plant Management and Professional Specifications and Contract documentation. The IPWEA maintains the traditional expertise of local • government engineering but by broadening the base of expertise and experience, adds a new dimension to public works professionalism in Australia. To enquire about IPWEA membership please contact • your State Division directly or email the www.ipwea.org.au 6
Introductions NATSPEC is a not for profit organisation that is • owned by the design, build, construct and property industry through professional associations and government property groups. NATSPEC’s major service is the comprehensive • national building specification system endorsed by government and professional bodies. Its main specification system to date has been • the specification for all building structures. It has specialist packages for architects, interior designers, landscape architects, structural engineers, service engineers and domestic owners. 7
Introductions NATSPEC’s aims are to provide economies of scale • for its shareholders and to improve the quality of construction in Australia via the provision of information, tools, products and services. NATSPEC is now the Publisher of the AUS-SPEC • series of Engineering Specifications The NATSPEC web page is at: • www.natspec.com.au • An order form for the AUS-SPEC series is included in • the written notes. 8
AUS-SPEC Up to date Continious improvements have been made to the AUS-SPEC documents, as listed below: • Reclassified to the National Classification system. • Restructured as per the construction sequence and to a new template. The Design and construction worksections for Buildings, Roadworks and Public utilities have been significantly revised. • Introduction of NATSPEC Maintenance reference, a reference book for building mainitenance contracts. AUS-SPEC Buildings package also includes the NATSPEC Buildings Basic package. 9

2. AUS-SPEC Series. 15
The new AUS-SPEC Series • Contracts Urban and open spaces • (Includes NATSPEC Site) Buildings • (includes NATSPEC Basic) Roadworks and bridges • Public utilities • • Maintenance (Non Parks) 16

AUS-SPEC Benefits and Objectives AUS-SPEC Contracts covers tendering, contract • preliminaries, quality checklists and quality requirements for the supply of projects and services. It includes sample documents which provide guidelines • for completing the tender and contract documentation, maintenance management plans and contract schedules for a maintenance contract. Appropriate AUS-SPEC TECHguides included provide • guidelines and examples to prepare the specifications. This package is for Contract, Supply, Asset and Works • Managers, Purchasing and Legal Officers. 18
AUS-SPEC Benefits and Objectives AUS-SPEC provides a readily available Library of a full range • of individual specifications for a myriad of applications. A well-maintained, quality specification keeps costs down by • reducing the number of project variations, disputes and correctional work. Without a correct specification the additional costs are inevitably borne by you, the client. Sound specifications reduce costs by allowing Contractors to • provide more honest and accurate tenders instead of inflated tenders because they do not know clearly what you want. • By using standard terminology across the industry, ambiguity of meaning is minimised. By using uniform Contract Documentation large economies of • scale are possible through staff training and Contractor familiarity of one standard instead a myriad of good, bad and ugly specification attempts. 19
AUS-SPEC Up to date • AUS-SPEC after 2007 is an update service, available to the local government Councils at a greatly reduced price via annual subscription. • AUS-SPEC 2013 is fully updated to the current industry standards, e.g. to Australian Standards, Austroads and WSAA. It is also reviewed by local government Councils and various industry organisations. • New design and construction techniques have been introduced in the design and construction worksections e.g. Water Sensitive Urban Design, stormwater harvesting and new design and construction techniques as per Austroads and WSAA standards. 20
3. Define the problem – An Amorphous Blob • Waiting to be told where the problems are ? • Different standards • Budget Resources – Staff/ Plant • • Inspections Politics – Policy development • • Risk Assessment 21
An Amorphous Blob ! 22
Waiting to be told where the problems are ? We will always be told where a pothole is or a ragged edge break, Should we respond to every request and have the patching crew drive all over the road network always catching up with any request. What constitutes a real problem ? 23
Different Standards Do all Gangs/Teams fill a pothole the same or even more importantly the correct way. The same goes for Edge break repair, rutting, alligator cracking ? Is all the plant and equipment for each Gang/team the same or most appropriate ? Is the materials being used the same or most appropriate ? Do we use a machine, say a Paveliner for all potholes even if it is not the best fix ? 24
Budget What is the right budget ? How much does the Engineer tell the Council is enough ? There is never enough ! The Asset management plan should tell Council what the renewal budget is but how big should the Maintenance budget be ? 25
Resources – Staff/ Plant How many staff is enough ? What skill set do they need ? How many trucks, backhoe’s, how many dog trailers ? How do we predict the quantities and at what cost ? 26
27
Inspections What do our Gangs/teams look out for ? Do we rely on the residents to tell us what is wrong ? What constitutes something that is valid from a sound Asset Management perspective ? 28
29
Politics Do we fix every Customer request to placate the Councillors ? Are we being true to our profession, the one we are being paid to provide advice from ? 30
Risk Assessment Do we comply with the Civil Liabilities Act ? Do we fix something because we are asked or fix something because it is needed ? Do we comply with our ethical obligations to safeguard the community or chase around trying to fix everything ? 31
4. Contract or Day Labour At this point I would like to emphasise that the processes defined here and in fact defined in AUS-SPEC are independent on whether Day Labour or Contract Maintenance is carried out. The only difference is how to define the level of service and at what cost. 32
5. The Logic – Cut into manageable portions Amorphous Blob Manageable Portions 33
6. The Solution – A Systems Approach › Segments / Precincts / Areas defined › Activity Specifications › Road Traffic Score › Split Inspection from Doing › Work Method Statements › Materials specified – Australian Standards › Levels of Service Intervention Level Response Time Compulsory Intervention Level › The Law – The Judges Response › Civil Liability › Proportioning the existing budget to Level of Service › Risk Management › Fine Tuning / Iteration 34
Segments / Precincts / Areas defined We now split the Council area into a set number of Segments, Precincts or areas. An existing Precinct will do, as long as each has approximately the same number of length of streets. This is easily done on a map/GIS. 35
