Seacliff Bridge Sydney NSW
Question: Discuss about the Seacliff Bridge Sydney NSW. Answer: Introduction The Sea Cliff Bridge has been balanced over a cantilever bridge which is located in New South Wales, Australia. This features the two lanes, cycleway and the walkway for people to enjoy the spectacular views from that area. The off-shore, parallel to the coast sea cliff bridge has been a part for the Grand Pacific Drive which was opened in 2005 with the total cost of $52million. The Bridge provides the road for driving, pedestrians, with the entire length of the 665m. It was constructed due to the larger embankment which slipped close to the Lawrence Hargrave Drive between Coalcliff and Clifton (which holds the entire stretch for the road areas for the falling of the rocks and the closures). Road History As per the observations, the Lawrence Hargrave Drive (which was earlier at the place of Seacliff bridge) was the best scenic road but with the rock falls and the embankment slips at the time of heavy rainfall lead to a total deterioration of the scenic beauty of the place. (Wilson et al., 2005). There were weathering of the rock features along with the weak rocks, which lead to the road closures as it can be seen by the image below: In 2003, the analysis took place about the slope risk profit which was unacceptable, thereby, forcing the closures of the road. The decision was taken to establish a platform for an Alliance design and the construction with multi-criteria analysis to deliver the optimised solution for the near shore bridge which contained both the in-situ balanced cantilever and Incremental Launch techniques. Design of the Seacliff Bridge The design is based on a balanced cantilever where the material used for the bridge has been steel reinforced concrete, with a total length of about 455.6 meters and a height of 41 meter. There have been longest spans in the area of about 3*108m. The bridge provides the coast between the battlement of the Illawarra Escarpment and the Tasman Sea which are beauty of the earth. (Chowdhury et al., 2008). The sea cliff bridge has been to set the costs for the average of $30 roundtrip from Sydney to travel to the area through car. Speciality of Seacliff The bridge runs 20km north of Wollongong which has been a contention for the aware of national engineering. The structure has been set to recognise the construction excellence with its iconic look and the innovation of the engineers. This bridge in NSW has got the construction rewards for the excellent engineering for the regional communities using the concrete material. (Cheaitani et al., 2006). The local Sea Cliff Bridge has been the tourist attract for the Grand Pacific Drive for the 60kms south from Central Sydney. The Safe Act Observation Program and Job Safety Analysis has been important to check on related training programs which include the working with the cranes and the traffic for the on and off site, fire training along with the emergency response specifics. The performance is based on different technologies where the Performance Review tea concluded the assessment of the quality of the concrete along with the design to be appropriate, thereby, reducing the problems of the maintenance issues in future. The place has the ability to handle the issues with the appropriate site review depending upon the requirements. Project Characteristics Involved The community has been involvement in the communication along with handling the regular mail-outs with explanatory brochures. The display has been to prevent the site run-off along with including the hydro mulch and gabion walls. Considering the characteristics of the construction: 1. The project has a specific target for covering a particular area which will be unique and includes the efficient resources for the construction. 2. The project construction of the area needs to be built up in such a manner which comforts the requirements of the owners and meet the project expectations. For the Seacliff bridge, it has been able to provide the walkway, cycleway and the best route for the scenic beauty. (Travelmag, 2016). 3. The construction project needs to hold the different activities with a particular time limit wherein, the work was completed in 2005 (as per the recommendation). 4. There is a need to accept the changes in the project, if any required, in the middle of the construction, and be ready with immediate action for the alternative way for the same. 5. The project of Seacliff holds the unique properties which gives the project manager the best way to adapt the changing circumstances along with handling the risks for the different project to reach the goal. The client satisfaction is important where the RTA expressed the same with complete control of quality along with handling the approval process successfully. The project has been entered into the significant contracts of alliance which has been redefined for the RTA in terms of the contract delivery. The benchmark for the same is for both the quality of the bridge along with the in-time finish of the project as per the proposal stated. All the attempts made by the best engineers met the cost effective solution and leads to the development of design and innovation. The safety of the Seacliff is based on measuring the Lost Time injury which involves the height safety issues with the operations based on the natural environment development. The major goal has been to deliver the lower risks for the public and work on the improvement with alteration set. The quality set has been based on concrete quality control with the independent performance that has led to the concrete quality, finish and the placement. As per the analysis, the total cost of the project aimed was $48m and the final cost came out to be $52m which is considered to be appreciable. The extensions to the walkway to the north along with the duct provision has been able to facilitate the alliance contract methods to handle the total outturn costs. (Travel BlackBoard, 2016). The assessment is based on handling the clients perception for the money where the importance is to achieve the concrete quality control. The quality, finishing and the placement has been the major aspect for the RTA, who have been able to impress the people through the efficient construction. The project major goal was to deliver the product with the lower risks levels to the public through the completed road structures. This led to the training and development of the project resources. The use of the different modifications has set the framework to enable the concrete setup for the eventual locations, thereby, preventing long drop s and providing a higher density for a better corrosion. The off-site production structure has a higher flow of the hydraulic ump which improves the turnaround times, leading to the early and easy completion of work. Conclusion As per the analysis, there is no bridge lighting at night and the NSW Roads and Traffic Authority (RTA) looks for the construction and the maintenance of the bridge in order to make sure that the visitors view is in the form of the best class structure. (Pitsis et al., 2003). The bridge has been the best solution for the locals to travel to the different places at their selected costs. RTA has been worked on handling the embankment slip along with taking hold of the development of tunnels, shelters and the bridges. The analysis is based on conducting the consultative research with the proper efficiency in the delivery and operations. The achievement of the time, cost and the quality has been the best objective where the sea cliff is able to be the best tourist spot. Reference Wilson, R. A., Moon, A. T., Hendrickx, M., Stewart, I.
