• title block indicating road name, kilometre, date of survey, and scale
(horizontal and vertical)
• special notes indicating land district, road width, survey level, and datum
of elevation
• all legal boundaries and plan numbers
• all monumentation found and tied within 300 m of the P-line, including a
traverse tie table.
A key map should also be included on the first drawing of the set to a scale
of 1:50 000. Note that no curves are required where I is less than or equal
to 5°.
Profiles should include the following information:
• chainage and elevation equations
• description of soils (at least every 200 m or at soil change)
• terrain features (creeks, rivers, swamps, wet areas, riparian areas, etc.)
• penetration depths at swamps and wet areas to solid ground, if possible
• grade lines completed with percent grades labelled (adverse or negative)
• grade breaks at grade changes of 2% or less
• vertical curves at grade changes greater than 2%
• turnout locations and dimensions
• design notes (extra ditching, lateral ditching, road widenings, etc.)
• culvert locations with recommended diameter, length, and skew
• kilometre stations
• primary excavation and primary embankment volumes summarized in
bank cubic metres at 200 m intervals
• secondary embankment (gravel) volumes summarized in bank cubic
metres at 200 m intervals
• waste and borrow locations, quantities in bank cubic metres, and quantity
movements
• scale: H = 1:2000; V = 1:200
• 100 m of existing road grade and horizontal alignment at junction
• balance points and direction of material movement
• position of cut and fill slope changes
