APRIL 9th, 2008 - O’Donnell Griffin Grows in Generation-To-Consumption Power Market - Investment opportunities in power industry more than $24 billion in next decade The Australian power industry is going through a period of massive investment that requires companies to provide a complete solution, from the generation of power through to its efficient delivery into homes and businesses. In response to this emerging need, O’Donnell Griffin (ODG) has launched a major initiative to offer a single solution to the issues of generation, transmission and distribution. The solution will will provide a “one stop stop” for electrical infrastructure investment. The strategic move by ODG has been instigated by Mr David Lee, Norfolk’s Chief Executive Electrical and Communications Division. ODG is part of Norfolk, an ASX listed company. Mr Lee said the power industry is undergoing a transformation not seen since the 1950s when Australia was transformed from an agricultural economy into a modern industrial economy. “Around $20 billion has been earmarked to spend on power generation in Australia in the next decade, with a further $4 billion to be spent upgrading the transmission system and this investment needs to be harnessed in the most efficient manner possible,” he said. As a result ODG, one of Australia’s leading electrical engineering groups, has restructured its operations to focus on the new investment opportunities. The focus of ODG going forward will be the provision of in-house specialists in design, engineering, managing technical detail, construction and installation. Mr Lee says these opportunities will increase markedly with the introduction of the cleaner power technologies required to meet the expected tough emission targets for 2020. ODG is positioning itself strongly in all sectors of the power generation-to-consumption market, he said, partly in response to the effects of deregulation over the past decade that has seen service providers needing to adapt to the new market conditions. “ODG has had to develop relationships with different stakeholders in generation, transmission and distribution, rather than with just one state-owned utility as was the case before power assets were sold off by some state governments as part of power reform,” he said. This is particularly important given the current level of consolidation occurring in the industry. “Overall the electrical industry is required to deal with different stakeholders and different drivers across the three sectors and the more the industry is able to deal with a single service provider the more efficient the outcomes will be,” he said. Mr Lee said ODG’s cross-industry reputation continues to grow, based on its extensive in-house expertise and its completion of multiple roles on major projects. “We’re doing power work across the country in all various aspects rail, mining and other industries as well as electrical infrastructure.” A recent ODG appointment is power industry expert, Mr John Roles, who as National Manager Power Generation is focussed on developing new power generation opportunities for the company. Mr Roles has a significant history in “total design-and-install power stations”, including involvement in Loy Yang A and B stations and more recently, Huntly Power Station in New Zealand, Pinjara co-generation facilities in Western Australia, and Condong and Broadwater co-generation facilities in NSW. He is a strong advocate of co-generation and biomass-fuelled power plants as part of a multi-pronged sustainable solution to Australia’s surging power needs. Mr Roles said the next generation investment opportunities in the industry will exceed $20 billion in the next ten years just to maintain the current level of supply. “If you take into account the costs associated with environmental issues, the potential of carbon-taxing, and the search for reliable clean renewable energy sources, there could be another $20 billion invested on top of that. “Even without carbon-taxing and environmental issues, about $2 billion a year needs to be spent nationally on designing, maintaining and operating power stations and its associated infrastructure,” he said. ODG also continues to build on its decades of expertise in transmission and distribution, says its National Manager, Power Industry Solutions, Mr Andrew Cross. Current industry ODG projects include $36.3 million contracts at the redevelopment of the coal terminal at northern Queensland’s Dalrymple Bay and a $1 million design contract for ETSA Utilities for Oxiana at Prominent Hill, he said. “At Prominent Hill, ODG is working with the project team and other key stakeholders to work through complex native title issues and restricted land-use issues (the site is near Woomera),” he says. “The company is involved in a $1 million contract value for tower and line design, developing a suite of towers for a highly variable terrain that includes sandhills and rocky ground, while also ensuring a reliable lifecycle in this environment of extreme elements. ODG will also be involved in ongoing consultation with the construction team.” ODG is exploring opportunities around the world in the power market, said Mr Cross, with involvement in powerline upgrade proposals in Brunei. In Australia there is also significant opportunity for ODG to provide services that boost the efficiency of supply via the upgrading of transmission powerlines across the national grid, he said.

APRIL 8th, 2008 - O’Donnell Griffin Wins $23 Million of New Contracts at Dalrymple Bay Leading electrical engineering group O’Donnell Griffin (ODG), part of Norfolk Group Ltd. (ASX: NFK), continues to expand its role in the $1.2 billion Dalrymple Bay Coal Terminal redevelopment with the winning of two new contracts totalling almost $23 million at the site. Current contractual works for ODG at Dalrymple Bay are now $36.3 million. The project, known as DBCT-7X, is based south of Mackay in northern Queensland. The two new contracts are for $17.4 million of works for the John Holland Pty Ltd and a $5.4 million contract with Gladstone-based Walz Construction Pty Ltd. These follow ODG’s initial $13.5 million contract at the site for lessee Babcock & Brown Industries (BBI) through site managers, Connell Hatch. ODG Project Manager, Mr Steve Jago, said the initial works involved a complete high-voltage upgrade of the site in just over 12 months. The works are due to be completed by early 2008. The $17.4 million contract with John Holland is for five kilometres of offshore conveyors, a new substation within the bay and a 400 metre extension to the existing berth. The $5.4 million contract with Walz Construction is for the onshore component of this extension, including the installation of transfer towers and an onshore conveyor system to deliver coal to the new offshore conveyor system. “The installation is going to be very demanding because in some areas we are going to be running cables out 30 to 40 metres above the water,” said Mr Jago. Both contracts are in planning and procurement stages with construction due to begin shortly. The new contracts follow a distinguished track record for ODG at Dalrymple Bay, with works completed so far meeting stringent time and budget targets while keeping the coal terminal running at near-full capacity during the upgrade, said Mr Jago. This has required careful planning of shutdowns and changeovers, he said. Mr Enrico Pecora, General Manager of ODG, said the company continues to forge highly co-operative and rewarding relationships with all parties involved in these projects, including BBI, Walz, Connell Hatch and John Holland. The John Holland contract follows previous works for the company on the adjacent Hay Point Coal Terminal expansion. “Continued success in the delivery of major mining projects across Australia solidifies ODG’s position as a premium provider of complete ‘mine to market’ electrical solutions,” said Mr Pecora. This seventh extension (7X) to the Dalrymple Bay coal terminal is part of ODG’s contribution to expanding Queensland’s infrastructure to keep pace with the rapidly developing demands of China and Asia. The upgrade will increase coal-loading capacity by more than 20 per cent to about 85 million tonnes, with completion of the new 3.8 kilometre jetty due by the end of 2008 The terminal facility handles and outloads onto bulk carriers thousands of tonnes of coal a day transported via electrified railway from the Bowen Basin. The upgrade addresses ongoing backlogs and bottlenecks in outloading the coal. Media Contact Grant Muller 0411 602 233
Leading rail infrastructure company O’Donnell Griffin (ODG) has completed the critical electrical infrastructure for Australia’s largest new rail line – Perth’s $1.56 billion Southern Suburbs Rail Project. The project was officially opened in late December 2007 and extends the South-west Metropolitan Railway, another 69 kilometres, from Perth to Mandurah. ODG’s role included the management, design, procurement and construction of the Traction Power, Signalling, Communications, Overhead Lines (Construct Only) and LV Power Systems. Commissioned by the WA Minister for Transport, the Public Transport Authority and project managers New Metro Rail, the rapid transit regional railway links local communities via strategically spaced and purpose-designed transit stations. As the principal sub-contractor, ODG completed contracts of a final estimated value of $102.96 million, including signalling communications traction power and overheads and management, procurement and installation works. ODG’s major suppliers were Ansaldo Rail Signalling equipment, Siemens OHL and TP equipment, Olex Cable Supply, Nexans Cable Supply and Silcar Communications. The works took place between the start of February 2006 and 23 December 2007, with more than 300 people employed by ODG on the project. More than 550,000 man-hours are estimated to have been used to complete the ODG component of the project. “O’Donnell Griffin’s record on the project, fulfilling substantial and demanding requirements in a complex environment attests to the company’s growing strength and credentials in the rail sector,” said Mr David Lee, Chief Executive of Norfolk’s Electrical and Communications Division. ODG is part of the Norfolk Group, an ASX listed company. The project’s completion follows ODG’s announcement last month that it has formed Australia’s first independent specialist rail division – O’Donnell Griffin Rail. The new dedicated rail division will be targeting major contracts as part of the $23 billion currently earmarked for national rail infrastructure development in the next 10-15 years. SSR links to the existing rail network via the tunnel that connects from Narrows Bridge in the South via Esplanade and William street underground stations, via the Roe Street dive to the existing Northern suburb lines. The project required linking the new line to the underground system built in central Perth and necessitated the complete shutdown of the rail system for four days in November. Mr David Howe, General Manager O’Donnell Griffin Rail, said “The most challenging part of ODG’s involvement in the project was the logistics of building a rail network in the middle of a freeway and transportation of 300 resources to different work fronts across 70 kilometres of construction site”. “This task became even more difficult once the track had been laid as the only access to a majority of the rail was via a purpose-built Hi-rail plant.” The project work-site for ODG was in excess of 70 km long by 40m (max) wide, Mr Howe said. Personnel had to work in between the lanes of Kwinana Freeway, Perth’s major freeway, making safety processes and management crucial. Overhead and signalling modifications had to be carried out to the existing, operating rail system in the Perth Yards to integrate with the new Mandurah line. This meant dozens of isolations and major shut-downs over a 12-month period. All up, 750,000 metres of cable was laid by ODG on the project, with 500,000 metres of overhead lines installed, with 2200 masts supporting the overhead line system. There are 160 new and 10 upgraded signals. Two electrical 132kv to 25kv sub-stations substations were built as part of the project, said Mr Howe, one at Glen Iris and one at Parklands, with 25,000 volts running through overhead cables. The completion of the SSR means that a journey from central Perth to Mandurah will take about 60 minutes, and 44 minutes to Rockingham. There will be an expected 30,000 passenger journeys each day. Mr Howe said it was a credit to ODG’s project management that the large $100-million-plus contractual works were completed to the final scheduled date, and in an intensive multi-partnership environment. “We would like to take the opportunity to congratulate those employees that were part of the SSRP team. Their efforts have lead to the successful completion of the project” said Mr Howe. Aside from the SSRP, ODG’s recent projects include BHP’s Rapid Growth Project – Rail, Regional Fast Rail (Victoria) and the Southern Alliance rail and signalling upgrades from Sydney to Melbourne, with rail work in recent years contributing towards the sustained growth of the business.

DECEMBER 21st, 2007 - ODG Commended on South Australia and Victoria O’Donnell Griffin South Australia and Victoria have both recently received National Electrical and Communications (NECA) Certificates of Commendation for projects they have worked on. ODG South Australia received their Certificate of Commendation for their work on the new 12 storey SANTOS headquarters building in Flinders Street, Adelaide. ODG were able to offer a complete Electrical Package for the project while their sister company, Diverse Data Communications. Completed the Voice Cabling, Access Control System and CCTV systems. The project also successfully received a Green Star 5 tick rating, one of the first projects in South Australia to do so. ODG Victoria won their award for both their Occupational Health and Safety and their work on the Middleborough Road project. The job encompassed the removal of the railway crossing on Middleborough Road in Box Hill and works first commenced in October 2006. The project was undertaken over a four month time frame and included the continual relocation and reconnection and commissioning of differing cable systems away from the workface and the provision of temporary power services to the workface.
DECEMBER 21st, 2007 - Norfolk lists on the ASX Norfolk, the parent company of O’Donnell Griffin, successfully listed on the ASX on the 27th of July. This is another milestone in the companies’ long term growth and development strategy. In undertaking this move, Norfolk will have access to liquid markets to support its growth strategies, which include:
DECEMBER 21st, 2007 - Southern Improvement Alliance Update The Melbourne to Sydney rail corridor upgrade is one of the largest rail projects of its kind in Australia. O’Donnell Griffin, part of the Southern Improvement Alliance, has successfully completed the installation of the signalling systems at Junee which has seen the Train Control Consolidation Commission (TCC) project pass the halfway mark. The new signalling system replaces old hand-operated semaphore signals and mechanical points with a more cost effective automated system centrally controlled out of Junee. At present the team are focusing on the Moss Vale and Cootamundra projects.
DECEMBER 21st, 2007 - On Target in Dalrymple bay O’Donnell Griffin is up to date in its involvement in the $1 billion upgrade of the Dalrymple Bay Coal Terminal Project, south of Mackay in Queensland. The first stage of ODG’s $10 million works, which includes the installation of four new substations, upgrading existing stations and shutdown targets on stacker reclaimers and conveyors is progressing very well, said ODG Project Manager Steve Jago. “The complexity of the work schedule and keeping the coal terminal running at near full capacity while these works take place is ever evolving and requires the ongoing synchronization of all teams working at the site” Jago said. The seventh upgrade to the Dalrymple Bay coal terminal will see coal loading capacity increase by more than 20 per cent to around 68 million tonnes with the completion of the new 3.8km jetty by the end of 2008. With over three quarters of the project completed, it is anticipated this project will be completed shortly.
DECEMBER 21st, 2007 - Warragamba Dam – Still Going Strong More than a year after being awarded the contract from the Sydney Catchment Authority (SCA) for the complete upgrade of Warragamba Dam’s electrical infrastructure, major progress has been made with this $20 million project. The upgrade of the HV/LV reticulation has been completed as has the communications voice and data systems around the dam. The upper and lower dam main switchboards have also been replaced. ODG has commenced replacing the lighting and power systems within the dam’s extensive service galleries contained inside the dam walls. The extent of these works can be seen by the fact that there is 6.5km of underground walkways and tunnels which need to be negotiated daily. Also completed is the replacement of the dam’s ventilation system and installation of a new fire detection system. In addition to this, new instrumentation and new SCADA and PLC systems, plus a new security and communications system have been completed. During the design process ODG provided alternative designs for the HV, LV and lighting systems which resulted in both cost savings to the client and allowed for more efficient operation and maintenance. The project is scheduled for completion in June 2008.

MAY, 2007 - O’Donnell Griffin Partners with Royal Rehabilitation Centre Sydney To Prevent Traumatic Injury
Sydney -- O'Donnell Griffin has made a major donation to the Royal Rehabilitation Centre Sydney Research Foundation for a research initiative to help prevent injuries. O’Donnell Griffin is celebrating 100 years of involvement with some of Australia’s most important major construction projects. Royal Rehabilitation Centre Sydney (RRCS), too, has also been working more than 100 years of working in partnership with their clients, many of whom have been hurt at work and at play. The initial project team of ODG Leadership Team and RRCS management and Board Members identified the need to find the cause of the behaviour leading up to a fall resulting in traumatic injury. Falls are the number one risk for our staff in the industry- and falls are the greatest cause of injury to clients at the Royal Rehabilitation Centre Sydney, often from a height under one metre. With experts across industry and clinical practice, the ODG/RRCS team determined the aim of this initiative is to ultimately influence the behaviour of people at home and in the workplace to prevent a traumatic injuries through falls. The Royal Rehabilitation Centre Sydney (RRCS) provides highly specialised, individual client-focused rehabilitation services for adults sustaining a wide range of traumatic injury and illness including neurological injury, spinal cord injury, stroke, traumatic brain injury, multiple sclerosis, Parkinson's disease, orthopaedic injury and amputations, and age related illness or disease. The ODG leadership team members, who attended the visit to the Centre’s facility in Ryde NSW, were impressed by the dedication and expertise of the staff and clinical associates, the range of rehabilitation programs available to the community and the types of care the Centre provides. “While financial contributions are very important to organisations like the RRCS, O’Donnell Griffin also sought to become more actively involved in a program we could identify and align ourselves with. Following discussions between the parties, an opportunity arose to fund a research project into the prevention of “traumatic injury from falls” together with the RRCS. The research project relates both to the community and the workplace and we are looking forward to implementing the learnings which may arise from this research. “ said David Lee, General Manager ODG. RRCS CEO Peter Williamson said, "O'Donnell Griffin has demonstrated industry leadership in exploring this issue to promote a safer workforce, and ultimately improve quality of life across its organisation and beyond." “We felt as a company, that we wanted to ‘give-back’ to the community, and participate in a community program that reaffirms our commitment to safety management and accident prevention not only in the workplace but every aspect of life. ” explained David Lee. “ODG is concerned with the safety and care of our people, and supporting the Royal Rehabilitation Centre seems to be a perfect fit for us as a leading Australian industrial contracting organisation.” “In addition, we will work with the Centre in building awareness and seeking support from other companies involved in the construction industry. We are excited about this community-based program.” Media Contact: Rachel Bejma, Royal Rehabilitation Centre Sydney (02) 9808 9268 Paula Downing, O’Donnell Griffin (08) 9479 8894.
APRIL 19, 2007 - ODG / DDC assist in finding Australian soldiers MIA in Vietnam Operation Aussies Home (OAH) today announced it had handed over to Australian authorities for finalisation the case of two Australian soldiers missing in action in Vietnam since 1965. A volunteer team from OAH has unearthed human remains and artefacts in on old battlefield north of Ho Chi Minh City in Vietnam. The team from OAH, Vietnam veterans, worked the site over the past four weeks and on Tuesday April 17, 2007 uncovered the remains of what is thought to be two people buried in a makeshift grave. OAH leader, retired infantry Lt Col, Jim Bourke said artefacts discovered in the grave strongly indicated the remains could be those of soldiers Lance Corporal Richard Parker and Private Peter Gillson who were killed on November 8,1965 and their bodies not recovered. “We have notified the nominated representatives of families involved about our find and advised them that Australian and Vietnamese authorities will formally identify the remains,” Mr Bourke said. “We are advised the Australian government is putting together a team, including forensic specialists, to examine what we have recovered and to excavate the site.” “We are confident, this brings to a conclusion a case that dragged on for more than 40 years,” Mr Bourke said. Four years ago, Operation Aussies Home began serious investigations amid scepticism from the defence bureaucracy and a major ex-service organisations. “But our own persistence, the support of many individual veterans and generous financial assistance from private donors eventually got us to a point where the evidence we had was so substantial the Minister Assisting Minister for Defence, Mr Bruce Billson gave us financing to carry out this final phase of the project,” Mr Bourke said. Central to the success of the search was the use of two high-tech ground penetrating radar (GPR) provided by Canberra-based Diverse Data Communications and The Australian National University. The volunteers supervised a team of local workers to clear vegetation and rocks from more than 4000 square metres of the hills side so that the GPR could be used to identify possible grave sites or former weapon pits; the two were known to have been buried in a weapon pit. A mechanical excavator was used to dig more than 30 separate holes in a bid to find evidence of the pits and hand digging was used in those areas where anything of interest was turned up. A number of other likely areas identified in May 2006 were also excavated. “As the team worked through the last pit where we found the remains, the diggers constantly whispered to the two men buried there, telling them they were now finally coming home,’ Mr Bourke said. “Vietnamese workers – without whom we could not have completed this huge task – laid incense and fruit by the grave site and said prayers in a Vietnamese custom which truly touched us all,” Mr Bourke said. “This is an issue that goes much further than just the families of those who went missing.” “Many former comrades have carried the failure to recover these two men with them since 1965 and have been counting the days since,” Mr Bourke said. “All members of the Battalion at the time felt the loss – it was as if a huge black cloud hung over us after that day in November 1965.” He said. Vietnam veterans in the team were leader Jim Bourke of Melbourne a two-tour veteran who served in the same battalion at the time they went missing, two-tour veteran, former Royal Australian Engineer Warrant Officer, Peter Aylett from Brisbane who supervised the search program and Sydney-based two-tour veteran Walter Pearson who acted as interpreter and liaison officer with local authorities. Former Army Reserve officer David Thomas of Nelson Bay supervised the excavations. Sydney lawyer Ray Latimer and Diverse Data Communications’ GPR Operator Jeffery Wullaert of Canberra did the final painstaking digging work to unearth the evidence. Paul Brugman from the Australian National University’s School of Asian and Pacific Studies and Jeffery Wullaert of Diverse Data Communications operated the radar machines and did the data analysis. Six Australian servicemen were killed in Vietnam and their bodies not recovered. A RAAF bomber crew and an SAS trooper remain not fully accounted for. In April 1971, a MEDIVAC helicopter crewman was killed in a crash in hills outside Vung Tau south-east of Saigon. Last month, on 21-23 March, OAH assisted a Department of Defence forensic investigation of this case. The Minister, Mr Billson is waiting for the report of the investigation. Operation Aussies Home expressed its thanks to Queensland businessman Mr Paul Darraouzet for his vital financial support and to the Minister Mr Billson, the first Minister to seriously pursue the issue of Servicemen missing in action in Vietnam. OAH also thanked all the individuals, veterans and non-veterans, who gave encouragement and support throughout this search.
MARCH 1, 2007 - ODG provides integrated signalling capabilities for $500 million Sydney - Melbourne rail corridor upgrade project Corridor works on the Australian Rail Track Corporation Ltd's $500 million Sydney - Melbourne Rail Corridor Upgrade project, which will reduce transit time by up to two and a half hours and increase the line's freight transport capacity, has commenced.

September, 2006 - New Upgrade Keeps The Water Flowing O’Donnell Griffin NSW has been awarded a contract from the Sydney catchment authority (SCA) for the complete upgrade of the Warragamba dam electrical infrastructure. the dam was opened in 1960 and stores 80% of sydney’s water supply. building started back in 1948, and it is the largest concrete dam in Australia, and when full, its lake is four times the size of Sydney harbour. ODG has the credentials for this task, having delivered similar projects including the Deep Water Recovery electrical installation for SCA previously. ODG Business Unit Manager, Mal Reid, said the project would completely replace the current electrical infrastructure within the dam walls, most of which hasn’t been upgraded since it was installed in the early 1950s. The upgrade is taking place over a wide area, and while this is happening, the facility has to be maintained operationally. Being Sydney’s main water supply continued operation is of paramount importance. Mal said the contract had to take into account substantial environmental factors and ODG has retained the services of environmental consultants ERM, to assist. There is also Heritage listings on some of the older equipment and ODG have engaged a consultant to film and record the changes made to the infrastructure. One of the older Switch Boards is to be pulled apart cleaned and given back to the SCA for their heritage presentation. The contract will be carried out in four separate stages, and incorporates design, HV/LV infrastructure and communication construction, and the PLC/SCADA maintenance. The job involves replacing an OH HV system with an underground Ringmain system. Replacing lighting and power systems within the dam’s extensive service galleries, including accommodation for potential flooding within the lower galleries. Replacement of the dam’s ventilation system, and installation of a new fire detection system. New instrumentation, and new SCADA and PLC systems, plus new security and communications systems. Mal said the timeframe for completion of the job was 90 weeks.
