CELEBRATING 25 YEARS: ENGINEERING EXCELLENCE AWARD 2013, ENGINEERS AUSTRALIA NEWCASTLE DIVISION As we continue to celebrate 25 years of Delaney Civil, we are looking back on our achievements over the last 25 years. One of our proudest is the Engineering Excellence Award we won in 2013 for the Engineers Australia Newcastle Division. Delaney Civil won this award for our work on the Duffs and Marlee Bridge Replacements project. This project involved the replacement of two timber truss bridges over Dingo Creek, along with roadworks on Bulga Road for the bridge approaches. The two bridges are located approximately 7km northwest of Wingham, on the NSW Mid North Coast. Each bridge replacement took place within a 10-day closure period, with Duffs Bridge actually being reopened on the 7th day of the planned 10-day closure. The innovative design solutions that Delaney Civil implemented on this project include: - Development of identical designs of the two bridges, presenting a significant cost saving - Using variable-sized culvert spans which catered for the difference in bridge length and hydrology requirements - The use of prestressed concrete planks with transverse post tension bars, which do not require an in-situ deck – meaning they are trafficable immediately and reduce closure times It was these innovative design solutions and construction approaches that led to Delaney Civil winning the Engineering Excellence Award for this project! #delaneycivil #constructionindustry #25years #EngineersAustralia #EngineeringExcellence #Award #Bridges

Stair removal projects demand construction expertise, consultant coordination & collaboration, and carefully considered site logistics to execute a successful project. The 737 Bourke St Stair Infill Project was no exception. A great project by all involved. #ThinkingTomorrowDeliveringToday #DesignAndConstruction #DesignAndBuild #WorkplaceDesign #CommercialInteriors #Fitout #WorkplaceInteriors #OfficeDesign #FitoutInteriors #MelbourneDesign #SydneyDesign

What are 10 facts about the Sydney Harbour bridge? 1. The world's heaviest steel arch bridge, about 53,000 tons of steel were used in its construction. 2. It is the tenth longest spanning-arch bridge in the world 3,770 feet (1,149 meters), 3. The top of the bridge stands 440 feet (134 meters) above the harbour. It carries eight lanes of traffic and two rail lines. 4. Over 2,000 people were employed to work on the bridge, including engineers, boilermakers, ironworkers, and stonemasons. 5. Before even the idea of the construction of a harbour bridge, the only way to cross the water was to go by boat. 6. At the time of its construction, the Sydney Harbour Bridge cost 10 million pounds to build – over 1.5 billion Australian dollars in today's money! 7. Named the Coathanger by locals. 8. It’s an essential part of the city; you can walk or cycle across it and even climb to its peak for incredible views. 9. The Sydney Harbor Bridge is so famous because Its opening in 1932 was pivotal in the development of modern Sydney and a focus for national optimism in the depths of the Great Depression. The Harbour Bridge has become an enduring national icon and the subject for many of Australia's foremost artists. It is one of the world's greatest arch bridges. 10. The bridge was built in eight years.  

There’s quite a drop on the far side of this universal column retaining wall (as you can see from the 7m markings currently above ground on the near side!) The timber lagging is being cut and installed before we build the formation for the #Railway up and reinstate the track. #NAL #CivilEngineering #Construction #GeotechnicalEngineering #Rail

Construction of the new Cave Hill Road pedestrian underpass is gathering pace.

In December we celebrated the successful completion of the replacement of the Barmouth Viaduct metallic spans, with Alun Griffiths (Contractors) Ltd. The key challenge of the replacement scheme was installing the new structure over the estuary without a heavy lift crane. The temporary works designed by Tony Gee allowed the new hogback trusses to be brought along the existing timber viaduct to the south on rail wagons and to be used as a temporary structure from which to demolish the existing trusses and lower them onto pontoons in the estuary. Once the existing spans were removed, the new trusses were jacked laterally into place. The above description neatly summarises a complex operation. Tony Gee developed a detailed sequence explained in 55 stages. Every step was scrutinised in conjunction with Alun Griffiths to avoid delays during the blockade and to leave nothing to chance. Key operations were tested in advance on a mock-up length of rail track. The trial involved testing transport of a complete span on rail wagons, jacking upwards and a lateral slide. Feasible configurations of the temporary works within the permanent works were very limited. To reduce the fabrication of bespoke steelwork, proprietary components were used for a temporary truss within the permanent trusses. This was beneficial to the carbon footprint, but required precise setting out of linking beams. The limited space is highlighted when the removal of the original slewing ring is observed, with the central pier remaining in service. If you are interested in discussing solutions to your asset management requirements, and how integrated delivery of temporary and permanent works add value then visit our team at Interchange, running from 27-28th Feb at Manchester Central. #barmouthviaduct #temporaryworks #detaileddesign #bethechange #TransportInfrastructure

Did you know the ancient Romans were some of the first to use concrete for road construction? Many of their roads are still in use today! At Concrete General, we continue the tradition of building strong, durable roads that stand the test of time. #triviaoftheday #constructioncompany #roadconstruction #heavyconstruction #marylandbusinesses
