Description of the problem: The attached bridge elevation and plan show the proposed bridge across the environmentally sensitive creek design and construct for RMS Roads and Maritime Services The contract was awarded as design and built contract. The team consists of a designer and contractor. The width of the bridge is m The bridge consists of three spans. The bridge is supported on two abutments at the embankment of the creek and two piers located within the creek Bridge abutment consists of five numbers of castinplace bored piles of diameter mm and connected by mm wide and mm deep capping beam. Bridge pier consists of a portal frame supported by single castinplace bored pile of diameter mm at each column locations. The bridge is partially restraint in the longitudinal and transverse direction. Bridge abutments and piers are provided with scour protection. Piles will be constructed without permanent casing Boreholes BR and BR are provided with tender design documentations. After the contract was awarded, two additional boreholes BR and BR were drilled. Four boreholes were available during detail design. Loading on piles for tender design and detailed design are tabulated in Table and Table respectively. Performance Requirements of Piles. Piles should be socketed into competent rock, Differential settlement between piles should be limited to mm The bridge should be stable for : year Ari flood.Q Based on design data provided during the tender, you are required to design piles for tendering. a Plot longitudinal rock profile b Estimate pile lengths for tender design by considering axial load only. c What pile lengths are you going to provide for estimating the tender pricing? d Please list at least three risks involved in your answer in Qc e Against risks identified in part d please suggests mitigation measures for each risk Q Copy the table provided and evaluate the average Risk Rating ARR and Geotechnical Strength Reduction Factor for piles in accordance with AS Clause Please write down the reasons for each rating on the column provided in the table. Q Based on design data provided for the detailed design, you are required to design piles for construction. Please use geotechnical strength reduction factor evaluated in a Plot longitudinal and transverse rock profile. b Calculate the pile length C Compare against tender design pile lengths in Qic. d Can you agree with your risksmitigation identified in Qid & Qie. Please justify your answer. Q Pile Testing a Please specify pile testing requirements in accordance with RMS Bridge Technical Direction. Please justify your answer. Q Understanding of construction specifications and preparation of construction drawings: a Please name the RMS Specification of construction of castinplace reinforced concrete piles without permanent casing, b Please tabulate the information you would like to provide for piling construction c Please develop at least five design notes to be provided in the construction drawing Q How to manage design issues during construction: It was observed that during the construction of piles, encountered rock profiles were different to what was assumed in the detailed design drawing. Construction manager provided the following information to the design team. Issue : At Abutment A pile No & encountered rock level is m lower than design Issue : At abutment B encountered top of socket material rock is m higher than the final design a What actions are you going to take to resolve the above issues? Please note that you have minimal time since construction is in progress. b Are you going to revise your pile lengths, if so please provide new lengths and justify your answer? c To alleviate similar issues in future designs, what suggestions are you going to give to your design team.
