Clash detection
Phase 1 calls for detecting physical and functional clashes between disciplines. Octo can prepare and organize the clash tests in Navisworks or IfcClash.
Deliverable: clash report by disciplineOcto and BIM in public works
In federal projects, BIM arrives agency by agency, phase by phase.
Decree 10.306/2020 requires BIM from the Ministry of Defense, for Army, Navy and Air Force properties, and from the Ministry of Infrastructure, for regional airports and for DNIT's special structures (bridges, viaducts and tunnels). It applies in three phases and only to the projects each agency deems relevant for spreading BIM; other federal agencies may adopt it. The BIM BR Strategy now sits in Decree 11.888/2024, and Law 14.133/2021 gives BIM preference in bids for construction and engineering services whenever it suits the scope. Octo can help your team put together the deliverables each phase calls for.

01
What Octo does for the deliverables.
Four possible deliverables, tied to the BIM uses Decree 10.306/2020 lists for each phase.
Quantities from the model
Phase 1 includes quantity takeoff. Octo can extract quantities from the model with a script and link them to the cost estimate.
Deliverable: quantity spreadsheet with its originDrawing documentation
It can generate and check drawing sheets from the model, in batch, in Revit or AutoCAD.
Deliverable: sheet set with a logPlanning and as-built
Phase 2 adds cost estimating, construction planning and control, and updating the model as built. Octo can organize the link between the schedule and the model and the log of changes.
Deliverable: proposed routine for the team
02
Eight arms, one contract.
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
Reads the bid notice
Which BIM uses the contract requires, whether the client and the project fall under Decree 10.306/2020, and in which phase.
-
Data
Lists the deliverables
Each required use becomes a deliverable with a format, a deadline and an owner.
-
Security
Respects the contract
Contract models and documents belong to the client and the contractor. Octo works only in the environment it is given access to.
-
Architecture
Picks the tools
The team's authoring software, IFC for exchange, Navisworks or IfcClash for clashes, a spreadsheet for quantities.
-
Development
Builds the routines
Exports, tests and reports for each deliverable, with the rule written down.
-
Review
Checks with coordination
Each deliverable is checked by the coordination team before it goes to the client.
-
Release
Delivers with your OK
Files go where the contract says, only with your approval.
-
Documentation
Logs the delivery
What was delivered, in which version, and who approved it.
Octo is not accountable for the contract. The deliverables belong to the contractor, and the client is the one who accepts them.
03
Each task, its own path.
The criteria Octo uses to choose. The tool your team already uses remains the reference.
| Required use | Path | Basis |
|---|---|---|
| Clash detection | Navisworks Clash Detective or IfcClash | Decree 10.306/2020, phase 1 |
| Quantity takeoff | Reading the model with a script | Decree 10.306/2020, phase 1 |
| Drawing documentation | Batch export in Revit or AutoCAD | Decree 10.306/2020, phase 1 |
| Cost estimating | Quantities linked to SINAPI cost compositions | Decree 10.306/2020, phase 2 |
| As-built model | Log of changes in the model | Decree 10.306/2020, phase 2 |

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
Phase 1 deliverables
Clashes, quantities and drawing documentation, with written rules.
- Clash tests by discipline
- Quantities traced back to the model
- Sheets in batch
Phase 2 deliverables
Cost estimate, planning and construction control linked to the model.
- Quantities linked to the cost estimate
- Schedule linked to the model
- Log of changes on site
Getting ready for 2028
Phase 3 also covers projects of medium relevance and adds management and maintenance after construction.
- Organized as-built model
- Information ready for operations

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
