Schedule linked to the model
It can prepare the schedule import (Microsoft Project, Primavera, Asta or CSV) into TimeLiner and the rule that links each task to the model objects.
Deliverable: link rule and list of what was left unlinkedOcto for construction planning and records
The schedule linked to the model, and the log up to date.
Navisworks TimeLiner imports schedules and links tasks to model objects to simulate construction and compare planned against actual. Octo can prepare these links, check the imported schedule and organize the construction records for your team.

01
What Octo does in planning.
Four possible deliverables. Planning and the official log stay with whoever the project and the contract designate.
Planned × actual
With actual dates recorded, it can build the planned-versus-actual comparison and list the tasks off schedule for the site meeting.
Deliverable: list of tasks off scheduleSequencing on IFC
With IfcOpenShell, it can work on schedules, critical path and sequence animation from the IFC.
Deliverable: proposal for the team to evaluateOrganized log
It can organize construction notes by date, location and subject, in the format the inspection and the team define.
Deliverable: searchable log
02
Eight arms, one project under way.
The same Octo cycle, applied to this workstream. Each arm has a narrow role; the people who approve and sign are on your team.
-
Discovery
Identifies schedule and model
Which program holds the schedule, which Navisworks edition the team has and how the model is split up.
-
Data
Sets the link rule
Which code or property links each task to each object. Without that rule in writing, the simulation can't be repeated.
-
Security
Respects the project
The schedule and the records belong to the client and the contract. Octo works in the approved environment.
-
Architecture
Picks the path
TimeLiner when the team already uses Navisworks; IfcOpenShell when the work starts from IFC.
-
Development
Builds the routine
Import, links and report, with the rule written down.
-
Review
Checks on a known stretch
Compares with a part of the project whose progress the team knows.
-
Release
Delivers with your OK
Leaves the simulation and the lists in the project folder.
-
Documentation
Records each update
Schedule and model versions used in each simulation.
Octo does not replace the inspector or the person responsible for the project. The official log is kept by whoever the contract and the law designate.
03
Each task, its own path.
The criteria Octo uses to choose. The tool your team already uses remains the reference.
| Task | Path | Note |
|---|---|---|
| Simulation linked to the schedule | Navisworks TimeLiner | In Manage and Simulate |
| Import the schedule | Microsoft Project (2007 to 2013, MPX), Primavera P6, Asta Power Project, CSV | Per the Navisworks help |
| Planned × actual | Actual dates in TimeLiner | Costs can also be assigned to tasks |
| Schedule and sequencing on IFC | IfcOpenShell | Critical path and sequence animation |
| Construction log on a public contract | The inspector's own log | Law 14.133/2021, art. 117 |
04
From request to routine.
Three steps. Each one only makes sense after the previous one has shown results on your team.
A proposal, not a promise
On-demand linking
You send the schedule and the model, and Octo prepares the import and the links.
- Written link rule
- List of tasks with no object and objects with no task
Weekly tracking
With actual dates, planned and actual are compared every week.
- List of tasks off schedule
- Organized construction log
Project recorded in the model
The as-built model and the construction log move forward together.
- Log of changes in the model
- Searchable construction history

What Octo does and what stays with you.
Octo prepares everything, but does not sign. The document of record stays with whoever is accountable for it.
Octo prepares
Surveys, calculates, organizes and produces the documents: spreadsheets, reports, drawing sheets and drafts.
Deliverable: material ready to checkYour team checks
The licensed professional checks what Octo delivered before signing. If something doesn't add up, it goes back to Octo with the correction.
Step: review by the signerWho signs
Octo does not sign. Designs, technical reports, ART/RRT (Brazil's professional responsibility records), accountability reports and any official document are still signed by the company's or agency's licensed professional: here, the responsible engineer or architect, with an ART or RRT.
Sign-off: engineer or architect, with ART/RRT

The schedule and the site speaking the same language.
The assessment starts with a schedule and a model your team already has, without changing anything. You get a proposal for what can be linked and tracked and decide with it in hand.
