Most residential driveway design follows the same sequence, from site information through to documentation the project team can rely on.
1. Gathering survey information
Start with the boundary RL, garage or slab RL, kerb and footpath levels where relevant, and any other survey levels. Gaps here turn into assumptions further down the profile. Getting the boundary and garage levels off a contour survey covers where those two numbers come from.
2. Confirming design levels and driveway length
Confirm the garage or target RL against the current architectural design, then measure from boundary to garage entry.
3. Understanding upslope and downslope conditions
Whether the site falls away from the garage or rises toward it changes which standard zone layout applies, and where transitions and drainage details are likely to sit.
4. Generating a preliminary profile
With boundary RL, garage RL and length established, you can generate a preliminary gradient profile to review rather than work it up transition by transition.
5. Reviewing transitions and vehicle clearance
Check rate of change between zones and, where relevant, clearance at the boundary and garage entry before the profile is finalised.
6. Producing documentation
Export a profile diagram with RLs, gradients and transitions so drafting, engineering, certification and site teams work from one reference.
