Site Survey, Risk and Layout Selection
Monitor whether planned traffic and pedestrian provision matches the actual site and applicable code.
How to prepare for supervisor assessment
Build the technical knowledge needed to judge work, then rehearse the supervisor evidence loop: review, observe, compare, intervene, record and verify.
Core concepts
Concept 1
The survey must consider road geometry, speed, traffic, work, plant, visibility, weather and nearby features.
Exam cue: Walk every approach as each road user.
Concept 2
Pedestrians and people with additional access needs require a continuous, detectable and usable route.
Exam cue: Compare real dimensions with the planned safety zones and lanes.
Concept 3
Code scope and any authority approval determine whether a standard layout is suitable.
Exam cue: Escalate layouts outside the code or available space.
Risk pitfalls and guardrails
Approving a drawing without a site survey.
Guardrail: Do not treat a card, checklist or previous site as proof that the current work complies; inspect the evidence and close every defect.
Treating pedestrians as an afterthought.
Guardrail: Do not treat a card, checklist or previous site as proof that the current work complies; inspect the evidence and close every defect.
Squeezing a standard layout into non-compliant dimensions.
Guardrail: Do not treat a card, checklist or previous site as proof that the current work complies; inspect the evidence and close every defect.
Memory anchors
Survey Before Signs
Reality determines the layout.
Every Approach, Every User
Check the site from all directions.
Measure the Safe Space
Do not estimate critical dimensions.
Outside Code, Escalate
Use designed control and approval.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
