Project Key Features:
 9.5km of dual track passenger rail from Richlands to Springfield
 Seven rail bridges, three road bridges
 Two rail stations – Springfield (near Woodcrest College) and
Springfield Central (near Orion Town Centre)
 Safety improvements to approximately 4 km of the Centenary Highway
and the Logan Motorway/Centenary Highway interchange

The project is made up of two phases – Design development and construction
delivery. Up until the award of this project the ABC design team has used client
supplied survey data to facilitate a design suitable for tender submission. One
data set was sourced from aerial photography mapping and the other an asbuilt ground survey via total station/RTK GPS of the Stage 1 works by others.
During the design development phase, one of my responsibilities, as the
project Survey Manager, was to assess the methods of data capture and
accuracies of the client supplied survey data, establish a survey control
network suitable for the construction and delivery of the project, and to advise
the design team on additional survey to be undertaken for the detailed design.
Later, I was to develop the project survey guidelines (Appendix A), establish
the project survey resources, supervise and direct these resources into
construction delivery.

As the project survey resources were not established during design
development, I developed a Project Brief (Appendix B) and invited a number of
consulting surveyors to tender on this early works scope. I engaged the
services of the successful proponent to observe and expand on the supplied
control network maintaining the provided co-ordinate system definition –
HAPG (Horizon Alliance Project Grid), to re-instate the cadastral boundaries of
the project corridor, undertake supplementary topographical and detailed
surveys.

After some initial auditory analysis of the supplementary topographical and
detail surveys I decided that much of the client-supplied data would be
suitable for majority of the design. I directed that ground surveys, with
optical/total station survey methods, were to be under taken where the new
design would interface with existing infrastructure, creeks and gullies where
heavily vegetated or steep terrain and areas that have been developed since
the initial surveys were surveyed with RTK and Total Station, dependant on
satellite visibility.

From previous experience, I was aware of the designers misinterpreting the
survey data, and in particular contourable and non-contourable features,
when translating data from Terramodel to other formats, even if triangulation
models were provided. I purchased a 12D software licence so that I could
process and supply the survey data in the same format to that being used by
the designers. This ensured that the designers could use the triangulated
1|Page
model as processed and supplied by me. I attended training in the use of 12D
for (2 day course) Detailed Survey and (2 day course) Design to Field
Calculations (Appendix C). I merged and analysed the client supplied data sets
replacing the data updated by the supplementary surveys paying particular
attention to the adjoining detail of the surveys and imposing a boundary line
to identify the limits and survey method used for each survey.

I designed and implemented a filing structure to manage the survey data
collected and to administrate all of the survey data for the project. I developed
a field data register to manage and track all field activities with a data folder
automatically created for each entry into the register. This data folder contains
all reductions and raw data for easy traceability and quality assurance. The
surveyor performing the survey is responsible for reducing their data collected.
This structure enables me to randomly audit reduction method and process
and review the raw data files. An example of the Field Data Register and folder
structure is attached in Appendix D. All survey and survey related data is
stored in the “Project Filing Index” which is backed-up daily. The compiled
survey feature and DTM data is revised regularly and transmitted to the
nominated design representative via the project document control package
“Keystone”. I regularly transform data between HAPG and MGA, using
Terramodel and 12D, for electrical and water Utilities to undertake service
relocation designs.

Once the detailed design was complete, and issued for construction, I was
responsible for calculating earthworks volumes and pavement materials, in
Terramodel, to compare with the tender take-offs and for project cost
forecasting. Earthworks are monitored on a monthly basis and I am required
to compile “end of month” surface models and calculate the earthworks
volumes completed. These volumes are formatted into an Excel spreadsheet
for ease of use and checking. Samples of these spreadsheets are attached as
Appendix E.

The project uses sub-contract plant fitted with Trimble, Topcon and Leica
machine guidance systems. There are approximately 12 excavators, 1 scraper
and 3 graders utilising both GPS for bulk earthworks and Trimble’s Universal
Total Station for final trim operations. I use 12D and Terramodel to create bulk
earthworks and detailed excavation models from design drawings, format files
for use in Trimble Business Centre, Topcon 3D Office, Leica Geo-Office and in
field applications – Trimble Survey Controller/Access, Trimble SCS900 and
Leica SmartWorks. I have acquired the skills to review and check data, create
localisation files and calibrate equipment from each of these suppliers and
software.
