Constrik
Constrik is a Spanish AI platform for construction estimating departments. It ingests BC3 budgets, IFC models and PDF drawings, then extracts quantities, assigns trades, audits errors and prices work against the contractor's own historical database.
What is Constrik?
Constrik is an artificial intelligence platform built for the estimating departments of Spanish construction companies. Its stated promise is to compress tender pricing that normally takes weeks into hours, and to keep pricing knowledge inside the firm rather than in the notebook of whoever prepared the last bid. The platform accepts three kinds of input: BC3 files, the Spanish FIEBDC budget standard, plus IFC building models and PDF drawing sets. From those it extracts quantities, maps each line item to the trade that will execute it, audits the budget for errors and estimates prices against the contractor's own history. Seven products sit on the platform and share the same BC3 file and the same model, so a firm can buy one tool or the whole set. The tendering agent parses BC3 files without losing detailed measurements, specifications or long descriptions, assigns trades, prices each item and prepares the subcontractor comparison, including parsing the PDF quotes that come back. The intelligent price database indexes every won project automatically, turning each line item into a 1,024-dimension vector so that a search for one wording finds a differently worded equivalent; every historical price can be traced back to its source file, chapter, awarded contract and date, and an inflation adjustment is logged whenever a price is reused. The IFC clash detector compares real triangular meshes rather than bounding boxes, ranks conflicts by overlap ratio and reconciles storeys by actual Z level. The drawing analyser sorts pages into 21 categories, proposes a scale, lets the user measure directly on the PDF once calibration is confirmed, and extracts column schedules. A Lean and Gantt planner schedules by trade and zone with configurable precedence rules and estimates indirect costs. Two further modules handle trade assignment and rule-based plus AI auditing of the BC3. Constrik positions itself as a complement to Presto rather than a replacement, and keeps a human in the loop on anything involving money: the AI proposes, the team validates, and nothing reaches the budget without explicit confirmation. Processing runs in the cloud.
What it does
- Price a tender from a BC3 file against your own historical database
- Audit a budget for unit errors, zero quantities, duplicates and empty chapters before you submit
- Map every budget line to the trade that will execute it
- Detect real clashes between IFC disciplines and rank them by severity
- Read, classify and measure PDF drawing sets at true scale
- Request, parse and compare subcontractor quotes against your own estimate
- Build a trade-level Gantt schedule and estimate indirect costs
When to use Constrik / When not to
A quick filter to help you decide if Constrik is the right fit.
When to use Constrik
- Spanish residential contractors whose pricing history is real but scattered across folders and people
- Estimating managers who already work in BC3 and spend their day copying and pasting between files
- Construction company directors chasing margin and wanting to choose which tenders are worth bidding
- BIM coordinators receiving separate IFC models per discipline and needing clash results they can trust
- Procurement and purchasing staff who solicit subcontractor quotes and must compare them against an estimate
When not to use Constrik
- Teams outside Spain: the data model is anchored on the BC3/FIEBDC standard and Spanish regional price databases
- Anyone who needs an English interface — the product and every page of the site are Spanish only
- Firms expecting native file support for closed formats such as .PZH or .PrestoObra, which are explicitly not read
- Independent estimators or very small firms with a single project, who still pay the full per-project monthly rate
- Developers looking to automate through an API, or anyone wanting a mobile app: neither exists
How to use Constrik
A typical end-to-end flow, from setup to results.
- Book a 30-minute video demo through the scheduling link on the site — there is no self-service sign-up
- Bring a real budget of your own: the vendor loads it during the call and shows what the AI extracts from it
- Once contracted, upload your historical BC3 files through the interface or connect them to your Presto installation
- Alternatively start from an empty database and let it fill as you win projects
- If your history lives in Excel, export it from Presto or as standard BC3, keeping code, description, unit and price on every line
- Let the engine index each won project automatically into semantic vectors — no forms, no manual tagging
- Upload IFC files per discipline, launch the job and poll its status to get clash results
- Upload a PDF drawing set, confirm or correct the scale the AI proposes, or calibrate manually by picking two points
- Review and adjust the 26 preloaded trades and the 29 preloaded precedence rules to match how your firm actually works
- Validate every AI price suggestion: nothing is applied to the budget without human confirmation
Pros & Cons
Pros
- Genuinely native to Spanish practice: BC3/FIEBDC, trades, indirect costs and regional public price databases are handled as first-class concepts
- Every suggested price is explainable — it exposes the cluster used, the references, the adjustments applied and a confidence level
- The AI is built to abstain rather than invent: it refuses to guess a scale it cannot read and flags unassignable items instead of forcing a trade
- Human validation is mandatory on anything involving money, and the vendor describes the chain as auditable end to end
- Published performance figures are unusually specific for this market, including the clash detection precision claim and model processing times
- Pricing is public and stated in one line, with no form to fill in before seeing it
- Modular: a firm can buy a single tool or the full platform, all working from the same BC3 file
Cons
- No service terms or subscription contract are published anywhere — the complete sitemap holds only eleven pages
- No data processing agreement is offered and no subprocessor list exists, for a tool that ingests budgets, signed contracts and BIM models
- The hosting country and region for customer data are never disclosed
- The vendor takes no published position on whether customer data trains shared models, and documents no opt-out mechanism
- Spanish only, with no English interface, no language selector and no international version
- No API and no mobile application, so automation beyond file import and export is not possible
- No about page, no named team and no social presence; the publisher describes itself as a company still being incorporated
Pricing & Plans
Constrik advertises neither a permanent free plan nor a free trial. A single price point is published: 250 EUR per active construction project per month, VAT excluded, billed monthly. The amount is a per-project rate rather than a flat subscription, so the invoice grows with the number of projects a firm keeps open; a customer may begin with one project and extend to the rest. Note that the figures of around one euro quoted in the site's FAQ refer to internal AI model processing cost, not to a customer tariff, and the site does not say whether that cost is passed on.

Data, GDPR & hosting
A consolidated view of how Constrik handles your data.
GDPR overview
The privacy policy is structured as a GDPR notice: it names the controller, the purposes, the legal bases (consent, pre-contractual measures and legitimate interest for site security), retention, recipients and the full set of data subject rights, all exercised at info@constrik.com. It names the Spanish supervisory authority, the AEPD, as the route for complaints, and it invokes the GDPR by name for international transfers, which it says are covered by appropriate safeguards such as standard contractual clauses. The legal notice is grounded in Spanish law and the LSSI-CE. All three legal texts carry a June 2026 effective date. What is missing matters too: no data protection officer is named, no processing agreement is offered to customers, and no list of subprocessors is published.
Who owns the data?
The data controller is Constrik Intelligence SL, identified by Spanish tax number B88773114 at Passeig Garbi 132, Castelldefels (Barcelona). Its published privacy policy covers only the marketing website: the contact details you submit when requesting a demo, and consent-based analytics. Nothing on the site states who owns the working data you upload — BC3 budgets, signed contracts, IFC models and drawings — because no service terms or subscription contract are published anywhere. On the product side the vendor states that each contractor gets an isolated workspace and that your budgets, awarded bids and trade catalogue are never visible to another organisation. Ownership of that content should be settled contractually before signing.
Reuse rights
The site sets out no reuse rights for customers, because it publishes no service terms. For website data, contact details are used to answer your request and manage the commercial relationship, and browsing data feeds Google Analytics 4 through Google Tag Manager, only with consent. Inside the product, your own history is what powers the engine: won projects are indexed into 1,024-dimension embeddings, grouped into semantic clusters and adjusted for inflation, and every suggested price can be traced back to the source file it came from. Constrik never states whether customer data also feeds shared models. Outputs such as schedules can be exported as CSV and XML, which is the only reuse path the site actually documents.
Data retention & training
Hosting summary
Constrik discloses no hosting jurisdiction. None of its three legal texts — legal notice, privacy policy or cookie policy — names a country, a region or a hosting provider for customer data. What the site does confirm is that processing happens in the cloud rather than on the customer's machine: files are uploaded, a job is launched and its status polled. The privacy policy acknowledges that some processing may involve international transfers, which it says are carried out with appropriate safeguards under the GDPR, such as standard contractual clauses. It refers to technology providers for site hosting and analytics acting as processors under contract, but names none of them. The only third party identified anywhere is Google, in the cookie policy, and only as the analytics provider for the marketing website — not as a processor of product data. Anyone with a hosting requirement will have to obtain this information directly from the vendor.
Things to keep in mind
Risks and trade-offs to weigh before adopting Constrik.
- No service terms or subscription contract are published: ask for them, along with notice and termination conditions, before committing
- No data processing agreement and no subprocessor list, even though the tool holds budgets, signed contracts and BIM models — a problem if your own clients audit your supply chain
- The hosting jurisdiction for customer data is undisclosed, which makes any transfer assessment impossible from public information alone
- Nothing states whether your data trains shared models, and no opt-out is documented; workspace isolation between customers is a different guarantee and does not answer this
- The price is per active project per month and VAT is excluded, so budget for growth in the number of open sites rather than a flat monthly line
- Performance claims such as the clash detection precision figure are the vendor's own internal measurements, published without third-party audit
- An engine that prices from your own history will reproduce your past mistakes as confidently as your good decisions; the confidence levels and audit trail exist for a reason and should actually be read
Setup & Integrations
Technical difficulty
Low technically, but gated commercially. There is nothing to install: the tool is web-based and runs in the cloud, and 26 trades plus 29 precedence rules ship preloaded. The vendor claims a first budget ready in under a day, with indexing happening automatically as projects are won. The real prerequisites are organisational: you must reach the product through a booked demo, since no self-service sign-up exists, and you need a usable history in BC3 or structured Excel, each line carrying a code, description, unit and price.

Should you pick Constrik?
Constrik is a narrow, deliberately vertical tool, and that is its strength. Rather than bolting generic document AI onto construction, it treats BC3 files, trades, indirect costs and Spanish regional price databases as native concepts, and the technical detail it publishes — mesh-level clash comparison, 1,024-dimension embeddings over past projects, seven named audit rules, column schedule extraction — reads like the work of people who have sat in an estimating department. Its handling of AI is notably disciplined: the system abstains when it cannot read a drawing scale, flags items it cannot classify instead of forcing them, exposes the reasoning behind every suggested price, and requires human confirmation before anything touches a budget. The reservations are not about the product but about everything around it. A platform that ingests budgets, awarded contracts and BIM models publishes no service terms, no processing agreement and no list of subprocessors; it names no hosting country; and it takes no position on whether customer data trains shared models. The publisher describes itself on its own legal notice as a company still being incorporated, names no team and maintains no social presence. Pricing is refreshingly public but deserves a second look, because 250 EUR is charged per active project per month, so the invoice scales with how many sites a contractor has open rather than staying flat. For a Spanish residential contractor already working in BC3 and Presto, with a real history worth indexing, Constrik is worth a demo — it is the only entry point on offer. Anyone else should read the contractual gaps carefully first, and ask directly for the documents the website does not publish.
