2) VERTICAL ALIGNMENT (20 MARKS; 14 for Design Levels, 6 for Low Point)
Complete this table by calculating the design level at every 10m of running chainage. Please indicate the TPs and IPs of each VC in the chainage column with the chainage. (e.g. 320 TP, 360 IP)
Your longsection must be pasted at the end of this answer file. Where possible please scan it.
(Please complete the chainages in the table as necessary for your unique design).

4c) Instructions to the Survey Party for any extra information you want them to collect along the Centre Line, to assist your final design. (6 Marks)
5) Volume Estimation (6 MARKS)
It is not essential that you use this table.
If you prefer to use another layout, please do so below this table. Ensure that you show the volume at the bottom of the page in the space provided.
Do NOT use these Natural Surface RLs for your longsection.
THEY ARE FOR THIS VOLUME CALCULATION ONLY.

6) Design Meeting Specifications (6 MARKS)
In your judgement, were all the design criteria met? YES / NO
If not, please explain or describe the problem area/s and briefly list the decisions you made, as to why your design is as it is.
