Gold Coast line initial construction documents circa 1996-1998, Helensvale-Robina documents circa 2006-2009. Internal memos, reports, consultant reports, design drawings or other design documents, as-built records. In particular: a copy of the pre-2009 Code of Practice - Railway Noise Management (2007) or similar version that was operational at the time of the design and construction of the Helensvale - Robina line duplication; the method of calculation and copies of calculations in relation to the increase in daily train movements through Carrara by approximately 20 per cent from 2009 (post line duplication) to [May] 2018 [together with] details of any off-timetable movements and average daily movements on this section of line before the Helensvale - Robina duplication; the civil engineering cross sections and plans be provided for the noise walls indicating: - coordinates of the position of the noise walls between Pappas Way and Nielsens Road; and - plans or cross sections indicating the RL (Reduced Level) above AHO (Australian Height Datum) of the top of the walls: a) before the Helensvale - Robina duplication; and b) after the Helensvale - Robina duplication; a copy of the noise modelling report for the rail design that informed the placement of the noise barriers for: the noise barrier design for the original rail line opened in approximately 1998; and the revised/updated noise modelling report for the revised rail design undertaken for the Helensvale-Robina duplication in approximately 2008; a copy of the document setting out [Queensland Rail's] planning levels and any associated documents relied upon to confirm whether existing adjacent residences were adequately attenuated and protected from these planning level; and [results from] rail noise monitoring undertaken in 2012 at the northern end of Paddington Drive and any associated report/documents including the position of readings and extent of noise measurement durations’.
