Complex & multi-stage traffic management plans
Getting the handover between stages wrong is one of the most common sources of delay and safety risk on large projects.
Large infrastructure projects rarely operate under a single, static traffic arrangement. Bridge upgrades, road widenings, major intersection works, and civil infrastructure projects typically progress through multiple construction phases, each with its own access requirements, barrier arrangements, and network impact. Sightline prepares the multi-stage TMPs that bring these elements together into one coherent delivery framework.
A standard TMP is built around one traffic arrangement for one work site. A complex TMP is built around a sequence — Stage 1, Stage 2, Stage 3 and beyond — where the traffic arrangement, barrier positions, pedestrian routes, and construction vehicle access all change as the project progresses.
Scope
Staged CAD traffic layouts — showing construction status at every stage
Barrier design & cross sections — confirmed at each stage, not just at project completion
Vehicle swept path confirmation — reconfirmed at each stage rather than assumed to carry over
Traffic modelling / SIDRA analysis — where the project affects intersection performance, at each stage
Staging transition documentation — clear drawing conventions showing what changes between stages
Risk assessment — reassessed across the full project timeline, not just once at the start
Our process
- 01
Scope the full staging sequence up front, covering the entire project lifecycle
- 02
Design staging layouts, barrier cross sections, and swept path plans together for each stage
- 03
Model network impact where relevant, confirming each stage — not only the final layout
- 04
Document transitions clearly for unambiguous handover on site
- 05
Submit the staged set to the relevant authority, tracking revisions stage by stage
- 06
Support delivery through construction, confirming design intent and managing amendments

How the engagement moves
From enquiry to controlled issue- Step 01Send the project
Provide the site, available drawings and the issue that needs resolving.
- Step 02Confirm the scope
We identify the required assessment, documentation, programme and fee.
- Step 03Assess and coordinate
The technical work is developed against the project and authority requirements.
- Step 04Check and issue
The agreed review is completed before controlled issue and support through comments.
Common questions
How does this differ from a standard TMP?
A standard TMP covers one arrangement for one site. A complex TMP covers a full sequence of stages, with staging, barrier, and swept path design developed for each phase — not just the final layout.
Does every stage need its own swept path and barrier design?
Where vehicle access, lane configuration, or barrier positions change between stages — yes. Carrying an earlier stage's design forward unchecked is a common and avoidable compliance gap.
Are mid-project amendments supported?
Yes — revised and reissued through the standard design change process, with revision history tracked on each sheet.
What's needed to scope a complex TMP?
The full project programme covering all planned stages, existing site geometry and survey, and the construction vehicles expected at each phase.
