Baserria 0.0 is a technical-digital system that converts a rural building into a living technical file. Unlike a conventional report — a static document delivered once — Baserria 0.0 generates a persistent data structure: each zone, element, pathology and intervention is recorded with a QR code, updatable history and scheduled alerts. The building is not diagnosed once; it is managed continuously.

The Diagnosis package is the entry point to the system. It includes a technical reading of the building by zones, identification of risks and pathologies, structured photographic report, recommended intervention phases and an indicative budget prioritised by urgency. It is sufficient when the owner needs to know the real status of the building before making decisions — purchase, renovation, sale or grant application. It does not include QR sheets or digital traceability; that corresponds to the Traceable package.

The Traceable package incorporates everything from Diagnosis plus the digital layer: QR sheets per structural element, technical documentation linked to each sheet, intervention history, scheduled alerts and reviews, and a client panel with digital access. The key difference is that the building goes from having a report to having a living file: any future technician can scan the QR of a beam and see its complete history, applied treatments and next recommended review.

The BHI (Building Health Index) is a metric from 0 to 100 that summarises the overall technical status of the building. It is calculated by weighting six categories: structure (30%), damp/water (20%), roof/envelope (20%), biological activity (15%), energy/use (10%) and documentation/traceability (5%). A BHI of 85 or above indicates optimal status; between 50 and 84, attention recommended; below 50, priority intervention. It is not a legal certification — it is a management tool to prioritise interventions and plan preventive maintenance.

The TCO (Total Cost of Ownership) is the projection of the real cost of maintaining the building over 10 years, comparing two scenarios: with Baserria 0.0 preventive maintenance (estimated at €1,200/year) and without maintenance (estimated at €80,000 accumulated through unforeseen emergencies). The estimated difference is €65,000–70,000 over 10 years. The TCO converts maintenance from a perceived expense into a documented investment with calculable return.

The Pilot is the complete implementation process of the system in 6 weeks: Week 1 — data contract, building access and zone definition. Week 2 — creation of digital sheets and QR installation in the field. Week 3 — BHI calculation and data model validation. Week 4 — client panel access and joint review of the file. Week 5 — 10-year TCO projection with preventive vs emergency scenarios. Week 6 — delivery of technical report, documentary video and maintenance plan. At the end, the building has a complete living technical file and the owner has permanent digital access.

Yes. The Baserria 0.0 diagnosis is completely non-invasive — thermography, resistography and moisture analysis without destructive contact — compatible with any level of foral or BIC protection. QR sheets are installed on inert supports (stainless steel or ceramic) in a discreet position. The documentation generated — causal diagnosis, minimum intervention proposal and QR traceability — is written in the format required by the Foral Councils and the French DRAC to justify actions before the Department of Culture.

A farmhouse can have structural pathologies invisible to the naked eye that do not appear in any registry documentation or in the estate agent's visual inspection. The most frequent: active rot in roof beams due to unresolved damp, established xylophage colonies in structural wood, masonry wall deformations due to differential settlement, and capillary damp in the ground floor. In 68% of the farmhouses we diagnose, we find at least one hidden pathology the buyer was unaware of. The cost of the technical review is between 12 and 18 times lower than the average repair cost of the pathologies it detects.

A standard architectural inspection is visual: the technician surveys the building, notes what they see and issues a status report. It does not include non-invasive diagnostic equipment. The Ondarezaintza review combines four data layers that visual inspection cannot obtain: (1) Thermography — detects hidden damp, thermal bridges and active xylophage colonies without contact. (2) Resistography — measures the real mechanical resistance of beams without removing them. (3) LiDAR — detects wall deformations of 3-5 mm that the eye cannot perceive. (4) Moisture analysis — quantifies moisture content in wood and masonry. The result is a technical report with measurable data, not a visual opinion.

Yes, and it is one of the most frequent uses. In 12-18% of the cases we diagnose, the buyer uses the report to renegotiate the purchase price downwards, with documented technical arguments. The process is: (1) The review detects pathologies with an estimated repair cost. (2) The buyer presents the report to the seller as technical justification for a price reduction equivalent to the repair cost. (3) The seller can accept the reduction, commit to repairing before closing, or maintain the price — in which case the buyer decides with complete information. An objective technical report has more negotiating weight than a subjective opinion.

Based on the 77 buildings diagnosed, the most frequent pathologies in order of occurrence are: (1) Capillary damp in ground floor walls — present in 71% of cases, especially in farmhouses with a plinth in direct contact with the ground. (2) Active xylophages in roof wood — detected in 58% of cases, mainly Anobium punctatum in pine wood and Hylotrupes bajulus in oak. (3) Deformation of floor beams — in 43% of cases, with loss of load-bearing section between 15 and 40%. (4) Roof infiltrations due to deficient junctions — in 39% of cases. (5) Active rot in beam heads embedded in walls — in 31% of cases, the most costly pathology to repair.

A complete diagnosis of a medium-sized farmhouse (400-600 m² built) is structured in three phases: (1) Field work: 1 day of 6-8 hours — drone flight with 4K + FLIR thermography camera, terrestrial LiDAR scanning of facades and interior structure, resistography of critical beams and moisture data collection. (2) Data processing: 3-5 days — generation of georeferenced orthophoto, 3D point cloud, thermal map and resistograph profiles. (3) Technical report: 2-3 days — writing of causal diagnosis, intervention proposal and documentation for administrative file. Total: 7-10 business days from visit to report delivery.

The terrestrial LiDAR scanner we use works with a precision of ±2 mm at distances of up to 40 m. It generates a 3D point cloud with densities of 1-5 million points/m² depending on the scanning distance. In architectural heritage, this allows: (1) Detecting masonry wall deformations of 3-5 mm that the human eye cannot perceive. (2) Measuring beam deflection with millimetre precision without contact. (3) Generating a 3D reference model to compare in future reviews and quantify the evolution of pathologies. (4) Documenting the pre-intervention status with legal precision. LiDAR does not replace the resistograph — it measures external geometry, not internal wood resistance.

The resistograph inserts a 1.5 mm diameter needle at a constant speed of 40 cm/min and records the resistance to advance in watts (W) along the profile. The resulting graph shows: (1) Healthy oak wood: resistance of 60-90 W, uniform. (2) Healthy pine wood: 30-50 W. (3) Soft rot zone: drop to 5-15 W. (4) Active xylophage gallery: peak of 0 W (void). (5) Node or compression zone: peak of 100+ W. Standard UNE 56544 establishes that a beam can remain under load if it retains more than 70% of its healthy load-bearing section. The resistograph allows calculating that percentage with precision without removing the beam or making destructive probes.

The symptom is what is visible: stain, crack, wood dust, smell. The cause is the active process generating it: structural damp by capillarity, thermal bridge, differential load, established xylophage colony. Treating the symptom without identifying the cause produces relapses in 12-24 months. The Ondarezaintza Method always starts with causal diagnosis: thermography, resistography and moisture analysis before any intervention. If you detect a recurring pattern, request a technical diagnosis.

The thermal camera records surface temperature differences. In an Atlantic farmhouse, this reveals: hidden damp by ascending capillarity in masonry walls, thermal bridges at beam-wall junctions, interstitial condensation zones and active xylophage colonies (they generate differential metabolic heat). Thermography is not a definitive diagnosis: it is the first data layer. It is combined with resistography and moisture analysis to confirm. Optimal outdoor temperature for inspection: between 5 and 12°C, with a minimum indoor-outdoor differential of 10°C.

Diatomaceous earth is amorphous silica of fossil origin. Its mechanism is mechanical, not chemical: the microscopic particles pierce the waxy cuticle of the insect's exoskeleton, causing lethal dehydration through fluid loss. It does not generate resistance because it does not act on any biological receptor. It is effective in localised application in cracks, joints and larval transit zones. It does not penetrate dense wood — for that, boric acid in aqueous solution is used. Toxicity for mammals: practically nil (oral LD50 >5000 mg/kg).

Synthetic biocides (pyrethroids, organophosphates) have rapid superficial action but do not penetrate dense wood more than 3-5 mm. A Hylotrupes bajulus colony works at 15-40 mm depth: the product does not reach it. They also degrade lignin in historic woods and generate persistent residues incompatible with heritage restoration criteria. Boric acid in aqueous solution penetrates by capillarity up to 20-30 mm, acts as a metabolic inhibitor of fungi and insects, and is compatible with wood, stone and lime mortar. No documented resistance in European xylophages.

Passive control acts on the conditions that allow pathology proliferation, not on the pathology itself. In an Atlantic farmhouse, the three vectors are: structural damp (capillarity, condensation, infiltration), insufficient ventilation in the air chamber and deficient water evacuation in roof and plinth. If these three factors are corrected, the wood reaches equilibrium moisture below 18% — the threshold below which neither rot fungi nor most xylophages can establish themselves. Point treatment without passive control has a service life of 3-5 years. Well-executed passive control, 20-40 years.

Each intervened element receives a QR code linked to its digital technical sheet: wood species, detected pathology, applied products with batch number, intervention date and next recommended review. The code is installed on an inert support (stainless steel or ceramic) in a discreet position. Any future technician, owner or administration can access the complete history by scanning the code. In listed buildings, this documentation is required by the Foral Councils to justify interventions before the Department of Culture. Traceability is not an extra: it is the difference between a documented intervention and one that does not exist administratively.

Three profiles we do not work with: (1) Those who seek the lowest price regardless of method — low-cost intervention without prior diagnosis produces relapses that cost more than the initial saving. (2) Those who need a solution in 48 hours without diagnosis — urgency without data produces irreversible technical errors in heritage. (3) Those who want a treatment certificate without real intervention — we do not issue documentation that does not support a verifiable technical intervention. We work with owners who understand that durability is an investment, not an expense.

We operate without restrictions in Euskal Herria (Bizkaia, Gipuzkoa, Araba, Navarra and Iparralde), the Cantabrian Arc (Cantabria, Asturias) and rural heritage in south-west France (Nouvelle-Aquitaine, Pyrénées-Atlantiques). For diagnosis projects in other Western European territories, we evaluate case by case. We have no absurd geographical limit: if the building justifies it technically, we travel. Displacement costs are always budgeted in advance.

In farmhouses with foral protection or BIC status, the replacement of original structural wood requires documented technical justification certifying the infeasibility of conservation. The regulation requires: a resistography report quantifying the loss of load-bearing section, an intervention proposal compatible with the original materials and a reversibility report. Replacement without this process is grounds for a penalty file. The Ondarezaintza Method generates exactly this documentation: technical diagnosis + minimum intervention proposal + QR traceability as support before the administration.

Three specific mechanisms: (1) Non-invasive diagnosis — thermography, resistography and moisture analysis without destructive contact with the asset, compatible with any level of protection. (2) Minimum and reversible intervention — low-toxicity products without persistent residue, localised application, without alteration of the original fabric. (3) QR traceability — each intervention is documented with a technical sheet, product batch number and date, in the format required by the Foral Councils and the French DRAC to justify actions before the Department of Culture. The Ondarezaintza diagnosis report is written to fit directly into the administrative file.
