Comparison Table
LinearPlus
vertical specialistEntry-level time chainage diagram software for linear projects such as tunnels, railways, and pipelines.
Time chainage diagrams recalculate from activity location mapping tied to a consistent route baseline.
LinearPlus is a specialist time chainage software used to produce time-location visuals from schedule data and a consistent chainage axis for planning and tracking workflows. It is built around an activity-to-location mapping approach so crews, workfronts, and look-ahead schedule impacts can be visualized on the same linear referencing frame. It also supports schedule update cycles where revised activities can be recalculated against the existing alignment model and stationing.
A key tradeoff is that accurate results depend on consistently prepared chainage inputs and stable alignment model definitions, because activity locations drive the diagram geometry and progress curves. It fits best when teams already manage a linear work sequence and need repeatable planned-versus-actual comparison for construction staging and access window decisions.
- +Activity-to-location mapping keeps schedule and chainage aligned
- +Planned-versus-actual tracking uses the same chainage references
- +Schedule update cycles recalculate diagrams from refreshed inputs
- +Linear work sequence visual outputs support production-rate context
- –Setup quality of chainage inputs strongly affects chart accuracy
- –Automation relies on defined input formats more than free-form edits
- –Cross-system synchronization can require manual refresh discipline
- –Advanced governance controls are limited for distributed teams

Program reporting standardizes chainage references so progress measurements remain comparable between sections.
Best for: Fits when planners need repeatable linear schedule-to-chainage reporting with controlled progress updates.
ScheduleReader
enterpriseViewer for Primavera P6 XER and XML schedules with a dedicated linear scheduling time-location chart view.
Position-aware diagram generation from schedule activities mapped to a chainage axis and kept stable across updates.
ScheduleReader is a fit for teams that need a location-time view tied to the same chainage axis used across planning, progress measurement, and site reporting. It converts schedule activities into position-aware visualizations built around a consistent linear reference, which reduces the friction between looking at a look-ahead schedule and validating where work is actually happening. The admin model is geared toward keeping mappings stable between updates, which matters when a schedule update happens frequently and chart changes must be controlled.
The main tradeoff is that schedule accuracy depends on having clean activity-to-location mapping inputs and a consistent route baseline definition. ScheduleReader works best when a single mapping method is used across teams so schedule updates translate into predictable movement on the chart. It is less suitable when planning information lacks reliable chainage or when location references are re-authored every week.
- +Activity-to-location mapping drives repeatable position-aware chart updates
- +Time chainage visuals support planned-versus-actual review in one view
- +Schedule update cycles keep linear work sequence aligned to route baseline
- +Workflow reduces manual rework when progress information changes
- –Chart correctness depends on consistent chainage and mapping discipline

How to Choose the Right time chainage software
This guide covers time chainage software used to produce time chainage diagram and time-distance chart outputs from schedule activities mapped to a chainage axis. It includes LinearPlus, ScheduleReader, ChainLink, Asta Powerproject, TILOS, SYNCHRO, Turbo Chart, and PlanaVista TurboChart.
Each tool card stresses different mechanics for keeping planned-versus-actual updates consistent with stationing changes. The comparison focus centers on how activity-to-location mapping is maintained, how progress is anchored to the same chainage references, and how much automation depends on defined input formats.
Time chainage software for planned-versus-actual linear scheduling and chart updates
Time chainage software links a linear schedule to a location reference so planners can visualize progress along a chainage axis in time chainage diagram and time-distance chart views. The core workflow maps schedule activities to a route baseline through activity-to-location mapping and then recalculates chart positions when schedule or progress changes.
LinearPlus is built around activity location mapping tied to a consistent route baseline so recalculations stay aligned across planned-versus-actual reporting. A contrasting example is ScheduleReader, which generates position-aware diagram updates from schedule activities mapped to a chainage axis and kept stable across schedule revisions. In both cases, chart correctness hinges on chainage and mapping discipline, with LinearPlus emphasizing controlled progress updates and ScheduleReader showing limits for ad hoc spatial changes per update.
Core evaluation features for time chainage software
Time chainage software succeeds when it maps schedule activities to a chainage reference so planned-versus-actual comparisons stay consistent across updates. Every tool in this guide ties time chart positions to stationing or an equivalent location reference so progress can be reviewed along the same chainage axis.
Activity-to-location mapping that preserves the chainage reference

Progress modeling tied to segment-level stationing updates with governance expectations
ChainLink focuses on earned progress that is tied to a maintained chainage reference model for segment-level tracking. Asta Powerproject also relies on station-based consistency, but it can require careful model structure to keep large projects updating fast.
Choosing the right time chainage software for linear planning workflows
The decision starts with how schedules are updated and how strictly stationing governance can be enforced. Tools differ in whether they recalculate from structured activity-location inputs or depend on stable mapping discipline during change control.
Select based on chainage reference stability during schedule revisions
If planned-versus-actual charts must stay aligned when activities shift, LinearPlus recalculates diagrams from activity location mapping tied to a consistent route baseline. If updates require position-aware chart generation that remains stable across revisions, ScheduleReader maps schedule activities to a chainage axis and keeps the visuals stable.
Pick the workflow style that matches how progress is maintained
If progress is maintained through controlled progress updates that reuse the same chainage references, LinearPlus supports planned-versus-actual reporting on shared chainage anchors. If teams run progress modeling through interval-based chart edits at stationing points, Turbo Chart and PlanaVista TurboChart provide chainage-interval update behavior.
Match your stationing rigor to the tool’s governance expectations
If stationing governance can be enforced and model structure can be maintained, Asta Powerproject supports station-based activity placement that stays consistent across schedule revisions. If governance discipline is less available, ChainLink highlights the need for strict governance of stationing inputs because segment-level chainage references drive earned progress reporting.
Choose by integration posture for schedule data movement
If schedule data movement into planning ecosystems must be automated through an API-first approach, ChainLink is positioned for integration-first workflows. If the integration requirement is anchored in Bentley alignment and construction geometry ecosystems, SYNCHRO offers a stronger integration path into Bentley design and construction toolchains.
Validate how the tool handles corridor work and time-distance chart outputs
If corridor and route baseline workflows require stationing-based progress modeling that outputs time-distance charts, TILOS updates time-distance chart outputs from linear work sequence inputs. If progress and schedule comparisons must remain anchored across planned and actual updates in a geometry-linked context, SYNCHRO keeps progress tracking tied to location-based sequences instead of time-only milestones.
Test whether your spatial change pattern is supported by the chart engine
If the team expects mostly controlled mapping changes and wants repeatable schedule-to-chainage reporting, LinearPlus is built around activity-to-location mapping inputs that drive recalculation. If the team expects ad hoc spatial changes per update, ScheduleReader notes lower effectiveness because chart correctness depends on consistent chainage and mapping discipline.
Who should use which time chainage software
Time chainage software is most effective for organizations that manage linear work and need schedule-to-location reporting that supports planned-versus-actual review along a chainage axis. The best fit depends on whether the organization can enforce stationing inputs and whether progress updates follow interval or mapping-driven workflows.

Common failure modes when adopting time chainage software
Most adoption failures come from chainage input discipline and from mismatched expectations about how updates should be applied. Tools can recalculate charts correctly only when activity-to-location mappings and stationing inputs remain consistent with the route baseline model.
Assuming chart outputs remain correct despite weak chainage governance
LinearPlus notes that chainage input quality strongly affects chart accuracy, and ChainLink flags strict governance of stationing inputs as a requirement for reliable segment-level earned progress.
Forcing ad hoc spatial changes into workflows that expect stable mapping discipline
ScheduleReader states that chart correctness depends on consistent chainage and mapping discipline and that it is less effective for workflows requiring ad hoc spatial changes per update.
Choosing chart-first interval editing when enterprise integration automation is the priority
Turbo Chart and PlanaVista TurboChart focus on chart-driven linear scheduling behavior and note that integration automation and API surface are not clearly positioned for enterprise systems.
Overlooking enterprise geometry or alignment interoperability constraints
SYNCHRO can require disciplined configuration of chains and mappings and may limit deep interoperability with non-Bentley design toolchains due to exchange format constraints.
Underestimating setup and model structure time for large projects
Asta Powerproject can require careful model structure for fast updates on large projects, and TILOS requires consistent stationing alignment and baseline setup discipline to keep time-distance charts aligned.
