Description

Title of the invention: Computer-implemented method for managing the deconstruction of a structure and the dismantling of an industrial asset

[0001] The invention relates to the field of deconstruction of works, such as buildings, or dismantling of any industrial asset or infrastructure.

[0002] In particular, the invention relates to a method for managing the resources of a structure to be dismantled.

[0003] In the field of dismantling, also called total, partial or selective deconstruction, cleaning or rehabilitation or renovation, a known problem is the need to process and recover as best as possible the resources from the dismantled structure.

[0004] Resource means all the constituent elements of the work, as well as the movable elements, products, equipment, materials and waste of the work.

[0005] It is known to evaluate all the products, equipment, materials and waste of the work, before proceeding with dismantling in order to determine the costs and the time necessary for dismantling.

[0006] Furthermore, the invention makes it possible to quantify and evaluate the savings in water, electricity and CO2 resulting from the reuse of PEMs which have thus been able to be reinjected into the cycle of production activities for new works, buildings, assets or infrastructure.

[0007] In particular, the invention makes it possible to identify PEMs eligible for reuse and to link them to a set of public or private databases which record the consumption of water, electricity and CO2 induced by the manufacture or transport of these same new PEMs.

[0008] This also makes it possible to anticipate the problems of waste management first, of the exit from waste status of products, equipment and materials (PEM), then and finally, of their reuse. Indeed, the dismantling of a structure can have a positive impact on the environment in terms of CO2 avoided, this thanks to the extension of the life of a product and the production of waste as toxic as non-hazardous. It is therefore appropriate to measure the benefits resulting from the reuse or re-use of PEM and to avoid the negative impacts on the environment that could be generated by the deconstruction, renovation, or rehabilitation of the structure, asset, building or infrastructure considered.

[0009] Thus, good anticipation of the waste produced makes it possible to reduce waste treatment costs and minimize the environmental impact.

[0010] This is part of a regulatory framework which must be respected. The dismantling of a structure is often subject to strict safety and environmental regulations. Managing resources before deconstruction or dismantling ensures that all applicable regulations are complied with, that PEMs are preserved as much as possible, and that delays, disruptions of any kind, or additional costs are avoided.

[0011] However, this resource management is usually managed manually, by global estimates carried out in the field.

[0012] There is therefore a need for a solution improving the management of resources of a structure to be dismantled.

[0013] To this end, a computer-implemented method is proposed for managing the dismantling of a structure, such as a building, comprising: - A step of providing a digital representation of said work; - A step of identifying a plurality of resources present in said work, said resources comprising structural elements, products and equipment constituting said work, the inventory stage comprising sub-stages of: • Positioning of each resource listed in said digital representation of said work; and • Characterization of each resource, based on at least one associated constituent material chosen from a predetermined list of materials, and based on at least one value representative of the quantity of material constituting said resource; - For each material associated with at least one listed resource, a step of calculating a value representative of the total quantity of said material listed in the work; - A step of establishing at least one set of summary data of the resources identified, suitable for optimizing the dismantling of said structure, based on at least one material classification parameter, and based on said associated material and said representative value of the quantity of material.

[0014] Advantageously, said material classification parameter is a parameter representative of the reusability of said material.

[0015] Advantageously, the method further comprises a step of managing the waste produced by said resources identified during dismantling, comprising: - A sub-step of calculating a total quantity of waste produced based on the materials associated with the resources identified and their representative value of quantity of material, - A waste classification step based on a waste typology parameter, and - A step of calculating the total quantities of waste by waste type.

[0016] Advantageously, the method further comprises a step of estimating the environmental impact of said dismantling comprising, for each material associated with at least one identified resource, the estimation of a quantity of CO2 emitted during the treatment of said material during dismantling, and as a function of said total quantity of material calculated.

[0017] Advantageously, the method further comprises a step of generating at least one set of summary data of the identified resources, adapted to optimize the dismantling of said structure, as a function of at least one resource classification parameter.

[0018] The invention also relates to a system for managing the dismantling of a structure, such as a building, comprising: - Means of providing a digital representation of said work; - Means of identifying a plurality of resources present in said work, said resources comprising structural elements, products and equipment constituting said work, said means of inventory being adapted for: • Position each resource listed in said digital representation of said work; and • Characterize each resource, based on at least one associated constituent material chosen from a predetermined list of materials, and based on at least one value representative of the quantity of material constituting said resource; - A calculation unit, for each material associated with at least one listed resource, with a value representative of the total quantity of said material listed in the work; and - A unit for establishing at least one set of summary data of the resources identified, suitable for optimizing the dismantling of said structure, based on at least one material classification parameter, and based on said associated material and said representative value of the quantity of material.

[0019] The invention also relates to a method for dismantling a structure, comprising the implementation of a management method according to any one of claims 1 to 5, - A planning stage for the dismantling of said structure based on the sets of summary data of the resources identified; and - A dismantling step based on said planning carried out.

[0020] Other features and advantages of the invention will emerge from reading the description given below of several embodiments of the invention, given for informational purposes but not as a limitation, with reference to the appended drawings in which:

[0021] [Fig. 1] is a flowchart of the method according to the first embodiment of the invention;

[0022] [Fig.2] is a flowchart representing several embodiments of the method according to the invention;

[0023] [Fig.3] is a schematic view of a digital plan representation of a level of building to be dismantled, and graphic elements associated with building resources positioned in superposition, implementing the method according to the invention;

[0024] [Fig.4] is an illustration of a graphical interface of a computer program implementing the method according to the invention; and

[0025] [Fig.5] is a schematic view of a system according to an embodiment of the invention.

[0026] The invention relates to a method 1 for managing the resources of a structure intended to be dismantled.

[0027] The method 1 according to the invention is notably described with reference to user interface functionalities associated with implementation by a computer, fixed or mobile, then taking, in the latter case, the form of a mobile tablet.

[0028] The method 1 according to the main embodiment, firstly comprises a step 10 of providing a digital representation 20 of a structure intended to be dismantled, as represented [Fig.3].

[0029] In the main embodiment of the invention the work is a building.

[0030] However, the invention is not limited to the building alone, and the present description can be adapted to the specificities of any type of structure. Indeed, within the meaning of the invention, the term structure includes any construction requiring planning with a view to its dismantling.

[0031] Thus, works include in particular any fixed infrastructure, such as a building, for example a house or a building, a factory or any industrial infrastructure, a warehouse, but also works of art, for example a bridge, a viaduct, a lock or a hydraulic dam. In addition, a work includes, within the meaning of the invention, any other complex engineering construction such as an aircraft, a ship, a vehicle and any asset whose design and manufacture was the result of a series of operations of arrangement of different resources together.

[0032] The supply step 10 comprises in this embodiment the loading into memory in an electronic device of a digital representation 20 of the work.

[0033] In particular, the electronic device here is a computer, a digital tablet, a multifunction mobile, called a smartphone, or any other electronic device comprising at least one screen and human-machine interface means, such as, without limitation, taken alone or in combination, a keyboard, a mouse, a touch screen, voice control means, gesture recognition means.

[0034] Indeed, in its concrete implementation on a computer, method 1 calls upon interactions with users which require human-machine interface means.

[0035] The digital representation 20 is, in the main embodiment of the invention, a set of plans, each representing a level or a part of the structure to be dismantled.

[0036] This provision may include in particular the digital transmission of a file on the device implementing the method 1, but may also include the design, for example by means of modeling or computer-aided industrial design, directly on the device implementing the method 1.

[0037] However, the invention is not limited to this type of digital representation 20 which may in particular also be, according to an alternative embodiment, one or more three-dimensional digital models.

[0038] This digital representation 20 is, in this exemplary embodiment, the set of level plans, or floor plans 20, of the building to be dismantled.

[0039] Such a level plan 20 represents the building, generally in top view, for a given level or floor, including the exterior and interior walls and partitions of the structure, building or asset, as well as the interior layout, circulation, clearances, openings, stairs and other access routes.

[0040] This digital representation 20 is adapted to be displayed via a graphical interface such as represented [Fig.3], for example on a screen of an electronic device.

[0041] A step 11 of inventorying resources is then implemented, such as structural elements, architectural or technical trades, cladding, decoration, products or equipment or materials constituting the work.

[0042] This inventory step 11 comprises, in this embodiment of the invention, an entry by a user, via human-machine interface means, of all the resources present in the building or a structure, after scaling the plan of the structure.

[0043] The census step 11 comprises two sub-steps:

[0044] - The positioning 110 of each resource in said digital representation of the said work; and

[0045] - the characterization 111 of each resource, as a function of at least one material associated constituent, chosen from a list of predetermined materials, of at least one value representative of the quantity of constituent material associated with said identified resource,

[0046] In particular, the characterization 111 can also take into account other physical or technical characteristics, the values ​​of which are also chosen from as many lists of values, defined by the user and derived from structured nomenclatures listing the components of the object to be deconstructed or dismantled.

[0047] Thus, with reference to [Fig.3], on the level plan 20, the user positions and sizes on the screen visual elements 31-36, here geometric shapes, superimposed on the plan 20, which constitutes the positioning of a resource.

[0048] In other words, the visual elements 31-36 correspond to the placement, for example carried out tactilely by the user, on the plan 20 of a resource existing in practice in the building or structure to be dismantled.

[0049] Thus, this positioning on the plan is carried out with reference to an observation of the reality of the work to be dismantled.

[0050] Each visual element 31-36 associated with a resource is stored in memory by being associated with a position on the plane 20, and with regard to its graphic representation, by dimensions and an associated shape.

[0051] The visual elements 31-36 are not limited to simple geometric shapes. They may additionally include, or substitute for, more complex graphic elements, such as icons or graphic representations of the resources to be inventoried, the contours of which are defined tactilely by the user.

[0052] In the present example of [Fig.3], certain visual elements associated with resources are thus represented in the form of a symbol, square, triangle or circle 32, or even in the more general form of a polygon 31, 33, 34, 35, 36, defined by the user and called here surface, or finally in linear form with the definition of a line or a line which can be straight or broken, depending on the drawing that the user makes of it on the touch tablet.

[0053] Each resource (product, equipment or material) is then characterized according to at least one associated constituent material, chosen from a predetermined list of materials, and at least one value representative of the quantity of constituent material associated with the resource.

[0054] Thus, as an example with reference to [Fig.3], we find:

[0055] - A room comprising a floor 31 made of wood material, such as parquet;

[0056] - Fire extinguishers 32;

[0057] - A bay window comprising metal and glass 33.

[0058] - Walls 34 containing in particular asbestos insulation;

[0059] - Another room 35 comprising a synthetic carpet floor;

[0060] - A metal entrance door 36.

[0061] These resources 31-35 are thus positioned on the plane 20, characterized as a function of at least one constituent material and a quantity of this material.

[0062] These resources 31-35 can also be specified more precisely according to certain characteristics configurable by the user.

[0063] In the main embodiment of the invention, the user associates during this inventory step each element positioned on the plan 20 with at least one material, selected from a previously provided list, and an associated quantity of the material(s).

[0064] The associated quantity can be provided in different ways: it can be, for example, a mass, a volume or even a percentage of materials constituting the resource.

[0065] In a particular embodiment, the inventory step 20 may comprise a prior step of providing a set of selectable elements, each element of the list corresponding to a resource that the user can position on the plan 20 and which will be associated with one or more materials.

[0066] Preferably, the user also has the possibility of selecting more precisely the material, if alternatives exist, and the quantity of materials considered, or another quantity such as a general mass of the element and proportions of material.

[0067] Thus, in this particular embodiment with reference to [Fig.4], a user interface, on which the digital representation 20 is displayed, offers a list 41 of positionable visual elements.

[0068] Each visual element, associated with a resource, can be characterized after having been positioned 42 via a window 43 displaying interactive fields making it possible to characterize or modify the material(s), and the mass of material associated with the resource, or any data relating to the quantity and / or the materials concerned, or any characteristic value selectable from the visual element itself.

[0069] Thus, the user can select an element while ensuring that the constituent material(s) are automatically entered and being assured of the uniformity of the entered data.

[0070] Advantageously, each visual element associated with a resource can be characterized by a main material and a secondary material of the resource.

[0071] This predetermined list can be stored in memory on the device implementing the method 1, but it can also be hosted on another server and accessed in real time by the device via a network, such as an internet or intranet network.

[0072] Thus, in a practical manner, the user visualizes what is present in the building or structure and lists them on the device displaying the digital representation.

[0073] The invention is however not limited to the sole manual inventory of the structural elements, products or equipment constituting the building as set out above.

[0074] The objective of this census step 11 is to constitute a digital equivalent of the work to be deconstructed or dismantled and to be able to qualify it.

[0075] Indeed, it is possible to provide, as an alternative, a census step 11 comprising an automatic image recognition module, for example by implementing deep convolutional learning methods. In such an alternative, the user provides visual and / or descriptive data of the building, such as a photo, a film of the building, and the automatic module detects and recognizes in said data the structural elements, products or equipment constituting the building, according to a database of predetermined elements associated with resources.

[0076] Once the inventory step 11 has been carried out for an entire building or structure, a calculation step 12 is implemented, for each material in said list of materials, of a sum of all the quantities of the material inventoried during the inventory step 11.

[0077] In other words, we calculate 12 a list of quantities of all the materials associated with at least one resource listed in the building.

[0078] Then a step 13 is implemented for establishing at least one set of summary data of the identified resources.

[0079] This set of synthesis data, also called synthesis, can be formalized in different ways in the implementation of the invention.

[0080] These syntheses are adapted to optimize the dismantling of the structure, according to at least one parameter of classification of the materials, and according to their associated materials and their value representative of the quantity of material in the structure to be dismantled.

[0081] In the main embodiment of the invention, several syntheses are thus generated:

[0082] - A first synthesis is carried out directly according to the typology of products and equipment, then the nature of the materials, and associates for each material a total mass corresponding here to the representative value of the quantity of material in the work to be dismantled, the percentage that this material represents in the work, and another mass calculated as being the mass of material of the work dismantled, and therefore excluding material retained after dismantling.

[0083] - A second synthesis is a synthesis of materials associated with the typology waste (inert waste known as DI, non-hazardous non-inert waste known as DNDNI or hazardous waste known as DD). Thus this synthesis associates each material with a classification parameter corresponding to whether or not it belongs to the waste typology, defined by European regulations with its associated code, called the CED code.

[0084] This second synthesis is also associated with the total quantity of materials of each material depending on the typology of waste.

[0085] - A third synthesis is carried out as a function of a parameter representative of the reusability of said material.

[0086] Thus, the materials are grouped by reusability classes and the total sum of the quantities is associated with each class. A fourth synthesis of PEMD is defined according to the treatment methods to which their waste can give rise, this on the basis of the Lansink scale Conservation Preservation of products after treatment of their hazardous components In situ reuse On-site reuse of products after treatment of their hazardous components Ex situ reuse Ex situ reuse of products after treatment of their hazardous components In situ reuse On-site reuse of products after treatment of their hazardous components Ex situ reuse Ex situ reuse of products after treatment of their hazardous components Recycling Recycling of products after treatment of their hazardous components Backfilling Composting Energy recovery Storage of non-hazardous waste Storage of non-hazardous waste products after treatment of their hazardous components Hazardous waste storage Undefined

[0087] Method 1 according to the invention does not necessarily give rise to the editing of the four preceding syntheses. Alternative implementations of the invention can including the generation of one or more of the preceding syntheses, as well as other material classification syntheses.

[0088] Furthermore, according to a second embodiment of the invention, which repeats all of the steps of the first embodiment, the method 1 also implements the step of evaluating the waste 14 produced by the resources identified during dismantling. In other words, the waste that could be produced by dismantling is estimated upstream based on the materials associated with the resources identified.

[0089] This waste evaluation step 14 firstly comprises a sub-step 140 of calculating a total quantity of waste produced as a function of the materials associated with the identified resources and their representative value of the quantity of material.

[0090] To this end, a correspondence list was established beforehand in order to associate or not associate a material with waste.

[0091] Then each waste is classified 141 according to a waste typology parameter, and a calculation step 142 of the total quantities of waste by waste typology is then implemented.

[0092] Among the types of waste, the following are defined in this embodiment, but in a non-exhaustive and non-limiting manner: Inert waste Inert waste other than concrete Inert concrete waste DNDNI DNDNI off-metal DNDNI ferrous metals DNDNI non-ferrous metals WEEE WEEE Non-Hazardous Dangerous WEEE Hazardous waste other than WEEE Undefined

[0093] According to a third exemplary embodiment, based on the steps of the first embodiment, and which may also be combined or not with the second embodiment of the invention, a step of estimating the environmental impact 15 of the dismantling is further implemented.

[0094] This estimation step 15 includes, for each material associated with at least one product or equipment listed, the estimation of a quantity of CO2 associated during the production of the product or equipment up to the treatment of the material during dismantling, in particular as a function of the total quantity of material calculated 12.

[0095] This estimate of CO2 emitted includes in particular the carbon footprint associated with its manufacture, its processing, its transport, and any element known within the framework of a carbon footprint.

[0096] The estimation of the CO2 generated is given as an example of this embodiment, however any other environmental parameter could be estimated by implementing the method according to this embodiment.

[0097] According to a fourth embodiment of the invention, based on the steps of the first embodiment, and which may also be combined or not with the second and / or third embodiment of the invention, the method 1 further implements a step 16 of generating a set of summary data of the resources identified as a function of at least one resource classification parameter.

[0098] In other words, the method 1 is suitable for generating summaries allowing tracking of products, equipment, materials and waste, for example by type of resource, by family of resource. These summaries are for example associated with quantities of resources of the same type or of the same family, by mass, by type of resource treatment, by type of transport, by type of dismantling.

[0099] It will be noted that in this fourth embodiment, the resources are thus synthesized independently of their material, but by other criteria such as their destination, use, or even type, or even the typology of waste to which these materials give rise.

[0100] Resources can be subdivided into several families, for example according to their dimensions or their location within the building or structure, and the definition of which by the user follows the nomenclatures corresponding to the structure, such as those for the enclosure and roof and the technical and architectural trades existing in the construction sector.

[0101] The method according to the invention can further be carried out by combining all or part of the preceding embodiments.

[0102] The syntheses set out above are notably generated, in a particular implementation of the invention, in the form of digital documents, such as digital text documents.

[0103] These generated documents may in particular include the automatic generation of regulatory or legal documents required in the context of the dismantling of the building.

[0104] The method according to the invention may further comprise additional steps and / or functionalities, which may be combined with each of the preceding embodiments:

[0105] During the census step 11, it is possible to add and associate with each visual element an observation, such as a textual or photographic observation.

[0106] During the census step 11, it is also possible to associate an attachment with each visual element, for example in addition to textual observations. The attachment may for example include an image, a text file, or any other digital content, compressed or not.

[0107] The inventory step 11 can be implemented a plurality of times, and at different times during the implementation of the method. It is for example possible to carry out a first inventory step 11 when drawing up an inventory of the building, or of any structure to be dismantled. Then the inventory step 11 can be re-implemented a plurality of times thereafter, in particular in order to complete, correct, or modify the previous inventory steps 11.

[0108] In particular, method 1 according to the invention can be implemented within the framework of dismantling monitoring. Thus, method 1 can comprise, in a particular embodiment, which can be combined with all the other embodiments described, dismantling monitoring steps.

[0109] This monitoring step includes in particular the addition to the identified resources 11 of progress information relating to the dismantling of these resources.

[0110] In addition, electronic signatures may be integrated with the data associated with the visual representation of the plan and the visual elements associated with the resources. These signatures may be added as part of the census step 11 or as part of the tracking steps.

[0111] In addition, method 1 according to the invention can be implemented in a framework collaborative. In other words, the steps of method 1, such as the census steps 11 or the monitoring steps, can be implemented in a decentralized manner for several users authorized to access and use the method, by several electronic devices implementing the method according to the invention, and sharing common data, for example stored on a remote server.

[0112] The term “data” here means the set of information acquired or entered by the user and generated by the method 1.

[0113] This data, whether common or not, can be stored in particular in the form of a relational database,

[0114] As explained above, method 1 allows in particular the generation of digital documents, also called reports, in particular regulatory or technical documents, such as:

[0115] The automated edition of a PEMD (Products, Equipment, Materials and Waste) diagnostic report providing information on the general features of a building or structure to be deconstructed, renovated or dismantled;

[0136] Furthermore, method 1 according to a particular embodiment of the invention allows the generation of a flowchart of the digital thread of the process of reusing the materials identified, making it possible to inform the buyers about the nature of the resources available at the end of the deconstruction, renovation or dismantling operation.

[0137] The invention also relates to a system 50 for managing the dismantling of a structure implementing a method according to one of the embodiments set out previously, or comprising the combination of several previous embodiments.

[0138] For this purpose, the management system 50 comprises at least one electronic device such as a computer, a processor, or any digital device comprising a human-machine interface, such as a keyboard, a mouse, a touch screen, or any other human-machine interface.

[0139] The system may be implemented by a single device, such as a computer, a digital tablet, a server, or a smartphone, or several separate devices.

[0140] According to an exemplary embodiment with reference to [Fig.5], the management system 50 comprises:
