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

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)

. 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

Assignment 1.a
Gantt chart:
The following is provides “network diagram” to obtain critical path of complete procedure.
As shown in above diagram, the “RED” highlighted is critical path of complete procedure.
a. Critical path = ADFGI L M N P
Duration = 0 + 2 + 8 + 9 +3 + 4 +3 +1 = 30
Total float =duration of critical path –duration of non-critical path
a. Non-critical path = AB E H->P = 0+ 3 +4+0 = 7
. Non-critical path = ACEH P = 0 + 3+4+2+0 = 9
c. Non-critical path = ADFJK O M N P = 0+2+8+6+3+4+3+1+0 = 27
d. Non-critical path = ADFGILMNP = 0+2+8+9+3+4+4+3+1+0 = 34
e. Non-critical path = ADFGH P = 0+2+8+2+0 = 12
1. Total float (a) = 30-7 = 23 days
2. Total float (b) = 30-9 = 21 days
3. Total float (c) = 30 -27 = 3 days
4. Total float (d) = 30 – 34 = -4 days
5. Total float (e) = 30-12 = 18 days

The most common used contracts are:
a. Lump Sum contracts
. Schedule of rates contracts
Management contracts:
As per provided requirement, the management contracts and tendering procedure is suitable for multiple activities. In this case, the supply and delivery of cadastral survey pegs and stakes to the large residential subdivision at the specific location. In this case, the project includes design, project planning and management for supply and delivery of cadastral survey pegs. The project manager will undertaking the work which must be ca
