Assignment extension policy
The penalty for late submissions of assignment work is documented in the
USQ Assessment Procedure link below, in practice penalty will be applied
at up to 10% per day late to a maximum of 2 weeks. This penalty may
e waived in part or in total where:
● failure to meet the due date for submission of assignment work was
due to ill-health or other reasons beyond your control, such as
excessive or exceptional work commitments and can be substantiated
y documentary evidence such as a medical certificate or a signed
statement from your employer.
● assignment extension applications must be lodged prior to the due
date of the assessment
● Students should refer to the USQ Assessment Procedure:

An equal tangent parabolic vertical summit curve is to be placed
etween two successive design formation grades of +3.0% and -2.0%
which meet at a point 700m at a reduced level of 33.2 m. The length
of the curve is 200 m. Compute and tabulate:
i. the calculated RL’s of the chainages/meterage along
the tangents; XXXXXXXXXX5 marks)
ii. the reduced levels of the design surface; (10 marks)
iii. the cut(-ve) or fill(+ve) required at each peg at the
centre line. XXXXXXXXXX5 marks)
. The centre-line of two railway culverts is required to be set-out from
the start of a transition curve, curving to the right. Calculate the
deflection angle and chord from the start of the transition curve using
the rigorous ideal transition curve formulae, using the following data:
Intersection angle = 20o19'50"
Radius = 350m
Transition length = 50 m
Start point (TS) of transitioned curve = 565 m
(i) Chainage/meterage of culvert one = 610 m
(ii) Chainage/meterage of culvert two = 680 m
(i 10 marks, ii 20 marks)
c. A surveyor when placing a fill situation catch point mark for batter
marking, measures the modelled catch point by the following data and
given information:
Height of collimation of level = 87.0 m
Design centre-line level = 86.15 m
SVY XXXXXXXXXXIntroductory book Page 5
Distance from the design centre-line to edge of shoulder = 5.0 m
Pavement crossfall from the design centre-line = -3%
Shoulder batter (-ve for fill situation) = -1: 0.5 (horizontal to
vertical) or -2: 1
Natural surface staff reading for catch point = 2.43m, taken at the
8m modelled offset from the centre-line as read off the
construction tables.
Calculate if the catch point is in the co
ect modelled position, and if
not, what would be a suggested shift, assuming the ground is level,
apply a check to your solution. XXXXXXXXXX20 marks)

Question 3 (70 marks)
a. Robert from River Adventures runs a white-water rafting company and
tells you that the Clearwater River varies in height over the season by
about 5 metres and this affects the raft speed. Based on the
information below. XXXXXXXXXX30 marks)
Roughness coefficient = 0.025
Hydraulic gradient = 0.016m/m
Acceleration due to gravity = 9.8m/s2
Calculate the (i) hydraulic radius and velocity of flow by Manning’s
Formula and (ii) rate of flow per hour for both the high water and
low water marks. (i 5 marks, ii 10 marks, for each water mark)

. The top of a pile requires final placement at E 100.8, N 200.6 and RL
50m (say for
idge/wharf/jetty construction). The pile is angled away
from the centre-line along the line of the piles, into the sub-surface at
a +10 angle off normal. The
idge centre-line has a bearing of 20
and the required line of piles to the left of the centre-line has a bearing
of 290. A measurement to the cu
ent position of the pile top has
een reduced to be at E 101.5, N 200.1 and RL 55.9m. Calculate the
equired movement of the pile top, so as to be positioned to
commence driving at RL 55.9m, along the line of skew. See plan and
elevation views below. XXXXXXXXXX30 marks)

At CP4 position of the level, six height pegs at 20 metre intervals
(100m in total) are to be set out at a falling grade of 1 in 420. The
first peg (i.e. 00) has a design level of 86.20m.
Calculate the grade levels and staff readings required for the top of
each peg using the Height of collimation booking method and enter
the results in level book form.
