1.4.5 Reporting [Amend this section into one report if a consolidated report is required] Provide a Factual Report, including the following as a minimum: Introduction, outlining scope and objectives Site description and regional geological setting Fieldwork methods and results Laboratory testing results Appendices as required to present all photographs, mapping, logs, field testing and laboratory testing. Prepare suitable plans showing all borehole and testpit locations, giving all grid co- ordinates, and also show the chainages and offset distances as measured on site from the existing bridges. Provide an Interpretative Report, with discussion on the following as a minimum:

Completeness and reliability of the field and laboratory testing Prepare longitudinal sections showing sub-surface soil and rock profiles for each bridge/culvert/crossing site, showing boreholes and test pits and other exposure information. The sections shall represent distribution of sub-surface soil layers, SPT values, moisture content and ground water levels (if encountered), and classes of weathered rock. Include Point load strength testing data. Geotechnical model appropriate for the proposed project, including a description of the engineering characteristics of the soils and rocks observed at the site. Extent of topsoil and unsuitable ground, including soft and compressible soil profiles Erosion control measures for temporary and permanent works. Recommend basic design parameters and tolerances on those values for use by bridge and road design engineers for the strength, stability, and serviceability design of embankment, culvert, causeway and bridge structures. Recommendations on pile and embankment design parameters, including, but not limited to; o Ultimate bearing pressures for pad footings, bored and driven piles as appropriate. o Shaft adhesion values for each soil and rock layer encountered, upwards and downwards. o Estimates of embankment settlements Discuss constructability constraints and methodologies (eg floating core stones, groundwater, collapsing ground, compressible soils, reactive clay profiles, variable depth to bedrock, strength reversal with depth etc). Geotechnical risks to be addressed by the designer Other information considered relevant and obtained during the investigation; Other report requirements: The report will be issued in draft form to the Department for review and comment. Any comments from the review shall be addressed and incorporated into the final report. Final report to be provided in electronic form as a pdf document. Allow for meetings with the Department to discuss the findings and finalise the report.
