NAME: …… STUDENT NUMBER …

Complete your answers in the spaces below and submit this word file.

Most of the tables have extra lines that you may not need to use so don’t worry if there are unused spaces.

1) Correction Factor for your Plan (2 Marks) Distances measured by you at 1:2,000 – show to nearest m.

100m Bar Scale ……. Correction factor for plan according to this line …. Line A – Y ……… Correction factor for plan according to this line …. Line Y – X ……. Correction factor for plan according to this line …. Line A – Ch 00 …… Correction factor for plan according to this line ….

YOUR CORRECTION FACTOR, …. Please give a brief reason why this factor was adopted

1) and 3) Both your plan and longsection will need to be scanned or photographed then copied and pasted to the end of this word document. (Presentation and data for Plan 2 Marks; and Longsection 5 Marks)

Chainages along the road

Location Chainage Start of Road 00

First Bank of River (by scale to nearest metre) Second Bank of River (by scale to nearest metre) Chainage of Hor. Curve TP 1 (to 2 decimal places) Chainage of Hor. Curve TP 2 (to 2 decimal places) Chainage of Hor. Curve TP 3 (to 2 decimal places) Chainage of Hor. Curve TP 4 (to 2 decimal places)

Chainage of end of Road (to 2 decimal places)

2) VERTICAL ALIGNMENT (25 Marks; 20 for Design Levels, 5 for Low Point) Complete this table by calculating the design level at every 30m of running chainage where there is no vertical curve and every 10m inside each vertical curve. 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 scanned or photographed and submitted as a separate file. (You may not fill every line in this table).
