General conditions of sale

My Digital Buildings, in Grenoble, January 20, 2026, version 1.3.

‍

Article 1 - Scope

‍

These General Terms and Conditions of Sale (“GTC”) describe the conditions for the provision of services, exchange and exploitation of data between customers (hereinafter referred to as “The Customer”) and the company OeKoumene 3D, a partner agency of the My Digital Buildings network (hereinafter referred to as “The Service Provider”), registered with the Grasse Trade and Companies Register under number 929 913 218. In the absence of a contract between the Service Provider and the Customer, the services provided are subject to the CGV described below.

‍

Article 2 - General provisions

‍

The Service Provider reserves the right to modify these terms and conditions at any time by publishing a new version on its website. The terms and conditions applicable then are those in force on the date of acceptance of the quotation or the order form. These Terms and Conditions are always available on the Company's website at the following address: https://mydigitalbuildings.com/cgv/mdb.

‍

Article 3 - Nature of benefits

‍

The Service Provider supports the Customer in the context of missions of advice, acquisition, acquisition, processing and exploitation of spatial data to create and use digital duplicates of their buildings and direct surroundings. These digital duplicates are translated into different representations such as: a point cloud, a realistic 3D model, a BIM digital model, a virtual visit.

‍

3.1 Surveys

‍

Survey missions are divided into four clearly identified phases:

• preparing the survey,
• data capture at the Customer's premises,
• post-processing of data and production of deliverables (point clouds adjusted, cleaned, plans, models, sections),
• delivery, optional publication on a platform, and tool training.

In the preparatory phase, the Customer undertakes to collaborate with The Service Provider in order to provide it with information allowing it to understand the objectives of digitization, to organize and plan the mission, to choose the materials and the actors involved and to assess the risks.

The Service Provider undertakes to use all necessary means to secure the confidential data transmitted by the Customer. For example, the Service Provider will provide the Customer with secure access to the Service Provider's platform to guarantee the confidentiality of critical data exchanges (for example: plans, photos of the building, administrative documents).

The Service Provider therefore takes care of and ensures that it collects all the necessary information allowing it to perform the services in accordance with the request expressed by the Customer. The Customer will make sure to provide all the necessary documents, essential for the good understanding of his needs and the development of an offer by the Service Provider.

This information concerning the Customer's site is as follows:

• exact address of the site and recommendations for accessing it, geographic coordinates if known;
• a direct contact on the site (a manager if possible);
• at least a global location plan (buildings, accesses); -
• plans of the floors and all the useful parts of the buildings to be digitized;
• photos of the areas to be scanned to better describe the environment and determine the congestion rate;
• a description of the spaces to be scanned with the location of the particular areas of attention.
• access constraints to the site and areas (risks, special procedures, accreditation and certification);
• the constraints of intervention dates (nights, weekends, stopping of production, etc.)

In the site survey phase, which consists in accessing all the areas that must be covered in order to capture data, the Customer undertakes to have the Service Provider accompanied by a manager in order to:

• make a prior visit with this contact to validate the areas to be surveyed, assess the constraints, the intervention schedule, the risks and organize the survey kinematics;
• provide a brief introduction to the people occupying the premises;
• ensure that the areas to be surveyed are in the desired condition;
• ensure that scanning operators operate safely and are not disturbed in their procedures.

The Service Provider's operators will wear clothing that makes it easy to identify them and undertake to replace items that could have been moved for the purposes of digitization.

During the post-processing phase, excluding extremely specific data security constraints, the treatments will be executed in the Service Provider's information system, including in a secure cloud. This phase includes the processing of data captured on the Customer's site with for example: filtering, cleaning, assembly, validation, analysis and conversions for exports.

Although this process is largely automated, it is still supervised by operators who establish verifications (visual, metric, analytical) at key stages.

The accuracy of point cloud measurements depends directly on the type and model of 3D scanner used, as well as on the protocol with which the data is captured. In general, as the precision decreases with the distance under which the elements of the space are viewed, the Service Provider will take care to establish a survey plan to guarantee the precision requested by the customer by limiting the distance between scanner and elements of the space to be captured.

The precision of the final point cloud assembly is directly related to the number of data sets to be assembled in which the error is scattered.

‍

3.2 Modeling

‍

The modeling is based on the point cloud captured and processed by the Service Provider's teams. The accuracy of this is therefore, unless otherwise indicated, based on the survey with an average tolerance of +/- 2.5 cm.

Except for special requests:

• all the levels of detail defined in batches in the quotation correspond to the levels of detail specified in our technical modeling brief.
• the base point and the topographic point will be positioned by the Service Provider's teams in a corner of the building. These may not be superimposed.
• the levels will be positioned at the highest point of the floor according to the point cloud.

All the information necessary to complete the model will be sent directly by the Customer prior to the project, such as (non-exhaustive list):

• The software and the operating format planned by the customer
• The modeling template
• The shared settings file

• The Uniformat ranking to take into account
• The decomposition of the model
• The naming convention
• Alphanumeric data to be integrated

The quantity invoiced on the modeling part will be the quantity actually processed by My Digital Buildings in agreement with the Customer and is therefore likely to be updated at the end of the modeling preparation period (see Article 4 - Special conditions - Limits and reservations).

Any additional request made during the modeling period is likely to change the delivery schedule defined initially.

The Customer has one (1) month after the project has been sent to return to the model so that the changes can be taken as a matter of priority. If this deadline is exceeded, the modifications will be made according to the availability of the BIM modellers.

‍

3.3 Access and use of data

‍

The data captured and processed will be stored on a platform offered by the Service Provider and accessible by the Customer at any time via his user account. An identifier and a password will be required to establish this secure connection.

The platform allows a first level of data visualization via a secure online application allowing navigation in the 3D universe and the virtual visit and can also provide all the deliverables and raw data.

In the event that the Service Provider's platform is used, it is recalled that it is developed by the Service Provider itself and was designed to meet the requirements of private companies and public authorities in terms of digital sovereignty, reversibility and integrity of the information system. We guarantee the following points:

• Sovereignty: the Service Provider's platform is a French solution hosted on servers located in France. The development is entirely done in-house which allows us total control of the code, updates, and data governance.

• Reversibility: All data captured, processed and analyzed by the Service Provider are and remain the property of the Customer. As such and at any time, all customer data (point clouds, 3D models, 2D plans, associated documents) can be exported in standard formats (E57, IFC, DWG, PDF). The Customer thus maintains full control of his data and can extract or integrate them into another system without technical dependence.
• Integrity of the IS: the Service Provider's platform integrates without disturbing the customer's IT environment. Access is partitioned, secure, in accordance with ANSSI best practices, with access logging and reinforced authentication.
• Scope of the data: the Service Provider's platform integrates fine management of access rights (by type of data or by business role), a complete versioning of spatial data, guaranteeing a high level of reliability and transparency on the origin, use and evolution of deliverables.
  ‍

3.4 Delivery

‍

All the material elements produced (point clouds, 3D models, virtual models, virtual visits, virtual visits, models, plans, etc.), excluding any knowledge of the Service Provider, are Deliverables and are the property of the Customer, subject to compliance with the terms of payment (see article 8). Unless otherwise agreed between the parties, the Service Provider will not provide any maintenance services for the Deliverables.

Delivery is organized with the Customer and it is during this stage that the Service Provider gives the Customer all the processed data that meets the expressed need. At the request of the Customer, the Service Provider can also deliver the raw data captured. After a final quality check, the data will be exported in standard formats compatible with the Customer's tools and deposited on the Service Provider's secure platform. The Customer will then be invited to download his data. If the Customer has subscribed to an archiving option, their data may be kept by the Service Provider, otherwise they will be deleted in accordance with the commitment made by the Service Provider and set out in the data management policy in accordance with the RGPD (“General Data Protection Regulation”).

‍

Article 4 - Special conditions - Limits and reservations

‍

In the event that the Customer does not provide the data requested by the Service Provider or if this data does not allow for a fair and accurate assessment of reality, the Service Provider may express reservations and adjust its commercial proposal accordingly in order to take sufficient margin to intervene. The Service Provider may also set a limit in order to limit the service using metrics that are quantifiable and verifiable by both parties and specify the methods of intervention for overruns, including in particular:

• If the intervention cannot be carried out within the estimated time, the Service Provider will transmit to the Customer the additional costs to be expected: day and accommodation. In the event of acceptance by the Customer, the Service Provider will schedule a new intervention without a guarantee of continuity and time constraints.
• If the georeferencing is not carried out by the Service Provider's teams or its subcontractors but on the basis of plans or data transmitted by the customer, the Service Provider cannot be held liable for the validity of the coordinates in particular and of georeferencing in general.
• The services of modeling, production of plans and models, work of exporting and publishing data on our platforms will be invoiced according to the actual areas measured. An additional estimate may be sent to the Customer by the Service Provider if the areas differ from the initial estimate after measurement in the data collected.
• In the absence of a BIM charter or agreement sent by the Customer prior to the start of the modeling project, the modeling elements applied will be those of the Service Provider's technical modeling memory.
• Any use by the Customer of a Deliverable is at his own risk and peril, for example the plans or models provided as an inventory and report by the Service Provider cannot be used for the purpose of carrying out work and the Service Provider cannot be held liable for a defect in design or execution.
