Tangl Value calculates volumes, work breakdown structure, and cost indices directly from the IFC model, while Tangl Control verifies the federated model for clashes — both without a classifier inside the project file. We don't sell or implement Tangl — we integrate its data to estimate and 1C.
Tangl requires a well-populated model: without it, Tangl Value won't calculate volumes and Tangl Control has nothing to verify. If working documentation is in 2D or the technical information model is maintained formally for approvals — that's not Tangl's scenario. Larix.EST is better then, which calculates volumes from both the model and designer specification in Excel when there's no model yet.
Our clients
Selection
| Criterion | Larix | Tangl |
|---|---|---|
| Source of quantities | Larix.EST — by model (Revit/IFC/Renga) or by designer specification in Excel if no model yet | Tangl Value — model only (IFC/Revit), no fallback to specification |
| Classifier — inside the model | Required — Larix.CDB codes are entered in the model | Not required — per vendor FAQ, classification codes are not entered into design programs |
| Working documentation still in 2D | Works — Larix.EST accepts the designer's specification as a standard scenario | Doesn't work — Tangl calculates only from a properly populated model |
| Tenders and contracts | Yes — Larix.Tender and Larix.Contract, CIS software registry #14076 | Tangl's product line has no procurement and contracting module |
| Result destination | To GRAND-Smeta, 1C:Smeta TIM CORP or equivalent — a volume schedule is not an estimate in itself | To Excel and estimating software via export — integration with 1C is built separately by the customer (TDSK case) |
Capabilities
Calculates volumes, resource schedules, estimate line items, and technical and economic indicators directly from the model in open IFC format — per vendor data, 'volumes in minutes' at any project stage.
Per vendor FAQ, Tangl's approach 'eliminates the need to work with classification codes in design programs' — unlike Larix.CDB, codes are not entered into model elements in Revit or IFC.
Automatically checks geometric clashes, information completeness, and compliance with product and regulatory requirements, covering up to 90% of EIR checks per vendor data; reports accumulate by model version.
Calculation and export of schedules to Excel with integration to estimating software and external ERP; an open API synchronizes Tangl with Revit, 1C, and Pragmacore — per vendor data.
Tangl's product line (Space, System, Control, Value, SDK) has no procurement or contracting module — the procurement cycle remains outside Tangl.
Tangl calculates from the model, not specification: if there's no model yet or working documentation is in 2D, Tangl Value and Tangl Control won't provide volumes.
Approach
The customer selects and deploys the platform. KT.Team works with what's already in place and doesn't substitute for the vendor.
TDSK (Tyumen Construction Company) piloted Tangl Value from March 2022: the generated works volume statement was uploaded to 1C. Source: ComNews, 29.05.2024, comnews.ru/content/233431.
Tangl exports volumes to Excel and estimating software; connecting this export to the customer's estimate and accounting system is separate work, discussed on this page integrating TIM/BIM with 1C, and the full scope of developer tasks is in the development digitalization. When you don't have a model yet or it's too early to implement a classifier — comparison with Larix.
AI compatibility
The volume schedule from Tangl Value is tied to the model, not formatted as free text — this is exactly the input KT.Team's AI estimator needs to suggest line items and coefficients instead of parsing PDFs.
Tangl Control stores verification reports by model version. Volume deltas between versions can be tracked automatically if connected to the accounting system — that's our integration workflow, not Tangl itself.
If Tangl data passes through KT.Team's integration layer on its way to an external model, contractor and counterparty personal data can be anonymized before transmission and restored on return at that same layer.
Tangl has an open API for synchronization with Revit, 1C, and Pragmacore — according to the vendor. An MCP wrapper reads volumes and verification status without replacing the estimator interface or modifying the product core.
