Questions 

1.    Define the following:
 
•    Linear Project
•    Time Chainage Diagram (4 marks)
 
2.    Prepare a construction schedule (having a start date of 1 January 2020) in Time-Chainage Diagram (TCD) format using AutoCAD, XL or other graphical software showing all activities to be undertaken for the construction of ¬your viaduct option which shall include site establishment, building a casting yard, casting of the viaduct segments and construction plant set up.  Include all assumptions and calculations for estimating construction activity durations. Detail on your TCD the finish date for the works and the duration. Assume that work on the viaduct construction site will be undertaken on a 6-day week basis.             (15 marks)

3.    Prepare a Construction Method Statement (see format in reference below) outlining the steps involved in the construction of all aspects of your viaduct option.  Include a detailed list of construction plant and equipment that would be utilised on the project.   Provide details of the hazards and risks involved in the project with particularly with the use of a SLI900 ‘bridge girder erection machine’ and the crane/s for erection of the precast concrete units for each of the piers.                            (10 marks)

4.    On large projects such as the PIB railway, an accurate assessment of progress on the project is essential.  It should be noted that a significant amount of information is generated on construction sites that maybe useful in assessing a contractor’s project performance (i.e. whether the contractor is ahead of schedule or behind).  The PIB project manager is investigating the tracking of project commodities for progress control whilst the railway is being constructed by tracking earthworks volumes, crushed rock and ballast stockpiles, quantities of rail and sleepers and viaduct construction as a minimum.  By reference to the paper (see below) by Birenza RM and Hildreth JC outline how this could be undertaken.
(8 marks)                                                                                 

5.    Tracking project commodities could conceivably be made easier using aerial drones or UAV’s to assess construction progress over the route of the railway. Outline how the above equipment could be used for aiding the tracking of the above, together with the amount of rail track that has been laid at various points in the contract.                                          (6 marks)
 
6.    Define what is meant by ‘long lead items’.  Many supply items for this project will be manufactured in Australia by original equipment manufacturers’ (OEM’s).  What procedures would you put in place to ensure that the OEM’s meet specified requirements and supply items are delivered to site on time?             (6 mark
