Description

BIM-based pipeline comprehensive arrangement method and system

Technical Field

The invention relates to the technical field of pipeline arrangement of buildings, in particular to a BIM-based pipeline comprehensive arrangement method and system.

Background

With the rapid development of the Chinese building industry, the structural design of buildings is more complex and diversified, so that the construction difficulty is greatly increased. Currently, the outstanding problems encountered in the construction process of buildings include:

firstly, the project construction management difficulty caused by the change in the construction process is improved. Due to the complexity, long-term and dynamic nature of construction project implementation, it is not possible for any construction project to anticipate and cover all possible variations in the project implementation at the design stage, and therefore alterations are inevitable for construction projects. Especially in the process of building pipeline design and construction, pipeline arrangement has various requirements such as systematicness, practicability, functionality, energy conservation and the like, so when pipeline arrangement is carried out on a building, the pipeline arrangement is influenced by various factors, and in the pipeline laying process, change is often required according to actual working conditions. However, such changes are extremely difficult for project construction management: the pipeline arrangement change relates to work changes of various departments, such as a design department, a construction department, a project supervision and acceptance department, a raw material purchasing department, a cost accounting department and the like, when the pipeline arrangement is changed, personnel of all relevant departments need to be gathered for discussion and determination, and corresponding specific work changes need to be made by working personnel of each process, so that the corresponding pipeline arrangement change can be realized, which undoubtedly needs to spend a great deal of time and energy, finally influences the project progress and the construction period and causes a great deal of economic loss. When the change requirement is not timely and accurately transmitted to each related person, or the related working information is not timely modified after the change requirement is known by the related staff, the management and construction can be disordered, dozens, even hundreds of times of small and large pipeline arrangement changes can be required during the construction of a building project, and the project construction management difficulty is high, so that the problems of construction conflict, repeated rework, material waste and the like in the construction process are endless.

Secondly, the construction precision and the construction accuracy rate are reduced due to the increase of the complexity of the design drawing. With the increasing requirements of applicability, attractiveness, comfort and functionality of people on shared buildings, houses and office areas, various pipeline types required to be introduced during building construction become complex and diversified, so that pipeline arrangement drawings become complicated, and for increasingly complex pipeline arrangement designs, on one hand, the requirement of the design on the construction accuracy is gradually improved; on the other hand, the difficulty of reading the drawing by the pipeline arrangement worker is increased, and when the pipeline arrangement requirement in the drawing cannot be accurately and comprehensively read by the construction worker, the construction correctness and efficiency are obviously affected, so that the construction difficulty is increased and the construction efficiency is reduced.

In recent years, with explosive development of the Building industry in China, the problems are increasingly highlighted, and based on the problems, Building Information Modeling (BIM) technology is rapidly popularized and applied in the Building field. The Building Information Model (BIM) technology is based on various relevant information data of a building engineering project as a model, building models are built, and finally real information of a building is simulated through digital information simulation, and the building models are used as a parameterized design, so that great convenience is brought to the work of designers such as architects, engineers and designers.

Generally, the BIM technology has completeness of model information, which requires that not only the 3D geometric information and the topological relation of the engineering object are described in the BIM model, but also the BIM model includes complete engineering information description, such as information in the aspects of object name, structure type, building material, engineering performance, etc.; construction information such as construction process, progress, quality requirement, cost and the like; maintenance information such as engineering safety performance, material service life, equipment maintenance information and the like; and engineering logical relationships between different objects, etc.

In addition, the model information in the BIM model has relevance, different objects can be identified and correlated, the BIM technology can carry out statistics and analysis on the model information and produce corresponding statistical analysis information such as graphs and documents, if some object changes, other objects related to the object can be automatically updated, and finally the purpose of keeping the integrity and the robustness of the model is achieved.

Therefore, the BIM technology realizes one-time digital revolution of the building industry, greatly improves the informatization level of building design and building construction, and provides a platform and a foundation for information coordination and integration among various professions and organizations.

At present, researchers and technicians in the field at home and abroad mainly concentrate on theoretical research, information technology research and engineering application research of the BIM technology, wherein for the building industry in China, the BIM technology is mainly used in the design stage at present, the strong guidance function of the BIM technology on engineering construction application is hardly exerted, and the technical problems to be solved in the field are one of the technical problems to be solved urgently through the BIM technology to guide construction, improve construction efficiency and construction accuracy, reduce construction conflict and reduce rework.

In the BIM technology, the BIM technology has very prominent advantages in the aspects of design, collision test and depth optimization of building pipeline arrangement, can greatly reduce the workload and improve the working efficiency, but the application of the BIM technology in the building pipeline arrangement is still limited in the design stage at present and is rarely applied in the pipe network arrangement construction stage.

Generally, the building pipeline arrangement includes heating ventilation, hydroelectric power, electromechanical and other types of pipeline arrangements, in the above several types of pipeline arrangements, a considerable part of pipeline components and equipment need to be prefabricated in advance and then buried in concrete and other structures, and finally form a hidden project in the building, for the hidden project, the correctness of the construction needs to be confirmed in time, and the specific conditions of the construction need to be recorded, otherwise, after the hidden project is covered, the installation condition of the pipeline components and equipment is difficult to obtain, and thus, when the construction deviation or construction error occurs to the pipeline components and equipment, the following problems will be caused:

firstly, construction deviation or construction error is difficult to find;

second, construction deviations or construction errors are difficult to correct;

thirdly, when uncorrected and recorded construction deviation or construction errors occur, later-period building maintenance is difficult to carry out;

fourthly, for pipeline components and equipment with larger sizes, when construction deviation or construction errors occur, a great amount of inapplicability of other components in the BIM model can be caused, so that the construction deviation or construction error information is transmitted to the BIM model in time in the construction process, and related components in the BIM model are updated in time so as to avoid influencing the smooth proceeding of subsequent construction;

fifthly, in order to improve the construction efficiency and shorten the construction period, a large amount of prefabricated parts are required for the construction of pipelines, the prefabricated parts need to be prefabricated in advance and then installed on site, but due to the variability of pipeline arrangement and the uncertainty during construction, when the construction site encounters unpredictable problems and needs to be designed and modified, but the model information in the BIM design model cannot be modified and changed in time, namely when a certain object is changed and other objects related to the object are not automatically updated along with the object, if the prefabricated parts are still prepared according to the original model information, a large amount of subsequent prefabricated parts cannot be used due to the fact that the construction working conditions after modification are not met;

sixth, because the installation order of the pipeline components and the equipment needs to be considered due to space and other limitations, the pipeline components and the equipment generally need to be installed in a certain order, which may result in the pipeline components and the equipment being unable to be installed, or needing rework, or needing repeated construction.

At present, the accuracy of pipeline arrangement construction is mainly confirmed on site through personnel such as supervision and administration, and the mode is low in efficiency and easy to make mistakes, so that all parties can mutually denie the soil, and the construction progress is influenced.

Further, in the step S344, the volume of each pipeline component and each pipeline device in the embedded pipeline are sequentially calculated, and according to the volume, each pipeline component and each pipeline device are divided into 3 intervals, namely a first interval with a volume greater than V1, a second interval with a volume greater than or equal to V2 and a third interval with a volume less than V2, wherein the first interval, the second interval and the third interval respectively correspond to a group of values of epsilon 1, epsilon 2 and epsilon 3, and epsilon 1 corresponding to the first interval is greater than epsilon 1 corresponding to the second interval and is greater than epsilon 1 corresponding to the third interval; epsilon 2 corresponding to the third interval is larger than epsilon 2 corresponding to the second interval and is larger than epsilon 2 corresponding to the first interval; epsilon 3 corresponding to the third interval is larger than epsilon 3 corresponding to the second interval and is larger than epsilon 3 corresponding to the first interval.

Specifically, as some embodiments of the present application, in step S1, the BIM design model may be created or updated by using Autodesk Revit software.

Furthermore, the Autodesk Revit software comprises an Autodesk Revit Architecture for architectural designers, an Auto CAD civil3D for civil engineers, an Autodesk Revit MEP for pipeline arrangement engineers, an Autodesk Revit Structure for structural engineers, and three-dimensional effect display software such as Navisworks, 3D max, AccuRender and the like, and through the software, designers in different professions can cooperatively work and share information.

The Navisworks software has a 3D roaming function, and a user can roam in the building model by the identity of a third party and check or check the internal structure and the effect of the building model.

As some embodiments of the application, the modeling process of the BIM design model may be performed by using an existing conventional modeling method, for example, a building model and a structural model may be created first, then pipeline arrangement models such as heating ventilation, hydropower, electromechanics and the like may be created, then collision detection and deep optimization may be performed, and finally, a designed BIM design model may be formed by auditing; wherein, the building and structure model has templates of the building and the structure, and the center file is created by elevation and axis network.

Taking the establishment of a heating and ventilation model as an example, the operation modeling is carried out by utilizing Mechanical, Plumbing and the like in Autodesk Revit software, and the modeling process mainly comprises the following steps: firstly, creating a CAD two-dimensional drawing, then linking the CAD two-dimensional drawing into Autodesk Revit software, simultaneously linking a civil engineering reference model into the Autodesk Revit software, and in the linking process, using a 'link Revit' function key in the Autodesk Revit software, and simultaneously positioning to an original point to ensure that files linked in are consistent.

Further, the pipeline comprises pipeline components and pipeline equipment, wherein the pipeline components comprise tubular components such as air pipes, water pipes and air pipes and non-tubular components such as valves, tees and elbows, and the pipeline equipment comprises mechanical equipment in a pipeline arrangement system such as end equipment and power equipment.

Furthermore, each element in the BIM design model, such as each pipeline component and pipeline device, is appended with corresponding building information, which includes geometric information and non-geometric information, where the geometric information is information measurable in a building, such as the shape, size, volume, location, etc. of the element; the non-geometric information comprises non-measurable related information such as time, space, physics, construction cost and the like, information such as the number, price, material, brand, model and the like of the element, construction information such as construction sequence, construction conditions, construction requirements and the like, and the BIM design model has the completeness of model information.

In addition, the model information in the BIM design model has relevance, different elements can be identified and correlated, the BIM technology can carry out statistics and analysis on the information of the model and produce corresponding statistical analysis information such as graphs and documents, if one element changes, other elements related to the element can be automatically updated, and finally the purpose of keeping the integrity and the robustness of the model is achieved.

Of particular note are: each element in the BIM design model is provided with a unique number, namely the number is in one-to-one correspondence with the element, and the building information of the element, including geometric information and non-geometric information, can be obtained by inputting the number of the element.

Further, in step S2, the construction is performed according to the BIM design model, where the construction according to the BIM design model includes the construction according to the requirements of the BIM design model, such as material, size, installation position, installation sequence, and installation process of each element.

Further, in step S2, when the concealed engineering pipeline needs to be embedded, a pipeline construction monitoring program is entered, and the specific entering mode may be performed in a manual identification mode or an intelligent identification mode.

As some embodiments of the present application, the method of entering a pipeline construction monitoring program by manual identification may be as follows: in the construction process in step S2, a construction sequence guidance file may be created, information such as construction time, construction requirements, drawings on which construction is based, and the like of each construction process are gradually and sequentially indicated in the construction sequence guidance file, and at the same time, it is also necessary to indicate whether each construction process includes concealed engineering pipeline pre-embedding, and a constructor needs to perform sequential construction, and when the construction reaches a process including concealed engineering pipeline pre-embedding, the construction process enters a pipeline construction monitoring program through manual identification.

As some embodiments of the present application, the method of entering the pipeline construction monitoring program by means of intelligent recognition may be as follows: in the design stage, determining whether each element in the BIM design model, such as each pipeline component and pipeline equipment, needs to be constructed according to a pipeline construction monitoring program, and adding information whether the element needs to be constructed according to the pipeline construction monitoring program into building information corresponding to the element, during construction, obtaining the building information corresponding to the element by inputting or scanning the serial number of each element, particularly the information whether the element needs to be constructed according to the pipeline construction monitoring program, and outputting corresponding prompt information for the element which does not need to be constructed according to the pipeline construction monitoring program; and outputting another corresponding prompt message for the elements needing to be constructed according to the pipeline construction monitoring program, and automatically starting the pipeline construction monitoring system and entering the pipeline construction monitoring program.

In addition, after entering the pipeline construction monitoring program, the construction sequence of the current number element is confirmed, and then whether the position of the embedded pipeline is correct or not is monitored through step S3.

Specifically, after entering the pipeline construction monitoring program, the method first enters the pipeline construction monitoring program through a manual identification or intelligent identification mode, so that the element number of the current embedded pipeline can be obtained, then the construction sequence is searched, the element number of an embedded pipeline before the element number of the current embedded pipeline is obtained, whether the pipeline construction monitoring program is performed on the element number of the previous embedded pipeline and whether construction is correct is confirmed through system storage information, if not, a construction sequence error prompt is sent, and if yes, the method directly enters the step S3 to perform construction monitoring on the element with the current number. Therefore, the construction sequence of the embedded pipeline can be ensured to be correct, and the phenomenon that the pipeline components and equipment are embedded by mistake and are leaked is avoided, so that the reworking is caused.

Further, the step S3 includes:

s31, placing the pre-buried pipeline, such as pipeline components or pipeline equipment, at a pre-buried position;

s32, acquiring the actual position information of the embedded pipeline;

s33, acquiring design position information of the corresponding embedded pipeline in the BIM design model;

s34, comparing the actual position and the design position of the embedded pipeline, judging whether the embedded position is correct or not, and if the comparison result is consistent, sending a construction correct instruction; and if the comparison result is inconsistent, sending out a construction error indication.

Further, in the step S31, the embedded pipeline may be directly placed at the embedded position, and is not fixed temporarily, after the actual position of the embedded pipeline is confirmed to be consistent with the design position, the embedded pipeline is fixed, and then concrete is used for embedding.

Further, in step S32, the actual position information of two different positions on the embedded pipeline should be obtained.

Preferably, the actual position information and the design position information of the embedded pipeline are three-dimensional space coordinate values, and the three-dimensional space coordinate values are obtained in the same three-dimensional space coordinate system. Namely, the actual three-dimensional space coordinate value of the embedded pipeline is consistent with the origin point and the three-dimensional space coordinate system according to the design three-dimensional space coordinate value. If a point in the external space of the building is taken as a coordinate origin, the three-dimensional space coordinate system is formed after the point extends along 3 same directions, a BIM design model is constructed according to the three-dimensional space coordinate system, the actual construction position is determined, and the actual position information and the design position information of the embedded pipeline are measured in the actual space and the BIM model respectively.

Further, in step S32, the position information of the central points of the inlet and the outlet are preferentially measured and compared between the non-tubular member such as the tee joint and the valve and the pipeline equipment such as the terminal equipment and the power equipment.

As some embodiments of the present application, the actual position information of the central portions of the inlet and outlet of a valve having one inlet and one outlet may be measured and compared.

In addition, for non-tubular members and pipeline equipment with only one inlet or only one outlet, such as terminal equipment with only one inlet and no outlet, the position information of the central point of the inlet is selected to be compared with the position information of the point on the terminal equipment farthest from the central point of the inlet, wherein the inlet can be an inlet of water, electricity, wind and other energy sources.

As some embodiments of the present application, for non-tubular members and pipeline equipment having more than 2 inlets and outlets, such as a tee, when the non-tubular element has more than 2 inlets and outlets, the positional information of the center points of the two furthest apart inlets and/or outlets can be chosen for comparison.

In short, the actual position information measurement of the non-tubular element can be set as required so as to facilitate the measurement and obtain the design position information of the corresponding part in the BIM software.

Preferably, the pipeline, such as a pipeline member and pipeline equipment, may be provided with detection point identifiers, the detection point identifiers are set in one-to-one correspondence with selected detection positions, and the positions of the detection point identifiers on the pipeline member or pipeline equipment are stored in the comprehensive arrangement system of the pipeline based on the BIM.

As some embodiments of the present application, information such as a two-dimensional code and a barcode is added to the detection point identifier, and by scanning the two-dimensional code or the barcode, the comprehensive pipeline configuration system can automatically obtain a three-dimensional spatial coordinate value of a corresponding detection portion in the BIM design model corresponding to the detection point identifier.

By setting the detection point identification, on one hand, a constructor can be quickly and accurately guided to measure the actual position of the selected measurement part to obtain the actual position information of the part; on the other hand, the comprehensive pipeline arrangement system can quickly acquire the design position information of the corresponding detection part.

Further, in step S32, the geometric centers of the two end portions of the tubular member, such as the air duct, the water duct, and the air duct, are preferably selected as the measurement positions, and the start position, the end position, and the length dimension of the tubular member can be obtained by measuring the geometric centers of the two end surfaces of the tubular member.

Preferably, for a tubular member having a small diameter, for example, a diameter of < 3cm, such as a strong electric wire or a weak electric wire, the position of any point on both end faces thereof can be directly measured, the position of the geometric center of the end face thereof can be represented, and compared with the design position information.

Further, in step S32, the actual position information of the embedded pipeline is measured by a three-dimensional spatial position detection device.

As some embodiments of the present application, the three-dimensional spatial position detecting device may perform three-dimensional spatial position detection by means of infrared, laser, sound, radio wave, satellite positioning, and the like.

Preferably, the three-dimensional spatial position detecting device is a high-precision three-dimensional spatial position detecting device.

More preferably, the three-dimensional spatial position detection device is a high-precision spatial position detection device with a detection error less than or equal to 1 cm.

Preferably, the three-dimensional spatial position detection device performs three-dimensional spatial position detection by sound. The sound has the penetrating capacity and can overcome the interference generated by the obstruction. Specifically, three-dimensional space position detection device includes the emitter 4 of sound, the receiving arrangement and the processing apparatus of a plurality of sounds, during the measurement, will emitter 4 is arranged in and is waited measuring the point, will the receiving arrangement of a plurality of sounds is arranged in different positions respectively, makes emitter 4 sound production, and when emitter 4 sounded the receiving arrangement of a plurality of sounds respectively received and recorded its sound that receives, later with its sound of recording send processing apparatus to carry out the analysis processing back and obtain the position that sound generating apparatus located.

Preferably, the number of the sound receiving devices is more than or equal to 5, the sound receiving devices are arranged at the positions with known space coordinates, and tests show that the requirements of the application on the detection precision can be met when the number of the sound receiving devices reaches more than 5.

More preferably, the sound receiving means is placed at the intersection point in the axial network.

As some embodiments of the present application, the process of detecting the position of the sound generating device by the three-dimensional spatial position detecting device is as follows:

firstly, arranging a plurality of sound receiving devices near a to-be-detected place;

then, placing the sound emitting device 4 at the place to be tested, and enabling the sound emitting device 4 to sound;

the receiving devices of the plurality of sounds respectively receive and record the received sounds and transmit the sounds to the processing device while the transmitting device 4 produces sounds;

and then the processing device performs data processing and analysis according to the received sound information, and finally obtains the three-dimensional space coordinate of the position of the transmitting device 4.

As some embodiments of the present application, the process of analyzing and processing by the processing device to obtain the position of the transmitting device 4 is as follows:

firstly, the processing device selects the sound recorded by one sound receiving device, separates the direct sound and the echo in the sound, calculates the energy ratio of the direct sound and the echo, and calculates the sound source distance D by using a direct inverse ratio method;

then, combining the receiving devices of the plurality of sounds in pairs, forming a pair of any two receiving devices of the sounds, and sequentially calculating an azimuth angle k between the two receiving devices of each pair of receiving devices of the sounds by positioning the spatial sound source of the binaural cue;

and finally, determining the three-dimensional space coordinate of the position of the transmitting device 4, namely the actual three-dimensional space coordinate of the transmitting device 4, according to the sound source distance D and the azimuth angle k.

For the detailed process of calculating the three-dimensional space coordinate of the position of the sound generating device according to the sound source distance D and the azimuth k, reference may be made to the three-dimensional space sound source positioning method disclosed in chinese patent publication (kokai) No. CN106291469A, and details thereof are not repeated herein.

Further, in step S33, for a tubular element such as an air duct, a water duct, or an air duct, three-dimensional spatial coordinate values of geometric centers of both end portions of the element may be directly acquired as design position information of the element.

Further, in step S34, for the pipeline equipment and the non-tubular member, the design position information of the corresponding position in the corresponding element in the BIM design model may be obtained according to the actual position measurement position selection method of the element.

For the sake of clarity and simplicity, the points corresponding to the actual three-dimensional space coordinate values of two different locations in the pipeline component or the pipeline device obtained in step S32 are referred to as point a and point b, the actual three-dimensional space coordinate value of point a is referred to as (xa, ya, za), the actual three-dimensional space coordinate value of point b is referred to as (xb, yb, zb), the points corresponding to the designed three-dimensional space coordinate values of two different locations in the pipeline component or the pipeline device obtained in step S33 are referred to as point a 'and point b', the designed three-dimensional space coordinate value of point a 'is referred to as (xa', ya ', za'), and the designed three-dimensional space coordinate value of point b 'is referred to as (xb', yb ', zb').

Further, in the step S34, the method for comparing the actual position and the design position of the embedded pipeline and determining whether the embedded position is correct is as follows:

s341, calculating an actual position expression f of the pipeline component or the pipeline device according to the actual three-dimensional space coordinate values of two different positions, the point a and the point b in the pipeline component or the pipeline device obtained in the step S32, where the actual position expression is an expression of a spatial straight line L passing through the point a and the point b in the three-dimensional space coordinate system;

s342, calculating a design position expression f ' of the corresponding pipeline component or pipeline device according to the design position information of two different positions, points a ' and b ' in the corresponding pipeline component or pipeline device obtained in the step S33, where the design position expression f ' is an expression of a spatial straight line L ' passing through the points a ' and b ' in the three-dimensional space coordinate system;

s343, calculating a distance m1 between the straight line L and the straight line L ', a distance m2 between the point a and the point a', and a distance m3 between the point b and the point b 'according to the actual position expression f and the design position expression f';

s344, calculating a deviation W between the actual position and the design position of the element, wherein W = ∈ 1 × m1+ ∈ 2 × m2+ ∈ 3 × m3, wherein ∈ 1, ∈ 2, and ∈ 3 are preset adjustment coefficients;

s345, judging whether W is less than or equal to W0, wherein W0 is a preset threshold value, if so, the comparison result is consistent, and sending a construction correctness indication; if not, the comparison result is inconsistent, a construction error indication is issued, and the process continues to step S4.

Further, in the step S344, the values of ∈ 1, ∈ 2, and ∈ 3 may be set according to experience or experimental results.

As some embodiments of the present application, each line member or pipeline device has a set of values ε 1, ε 2, and ε 3 corresponding thereto or a set of values ε 1, ε 2, and ε 3 corresponding thereto for each type of element.

Preferably, the epsilon 1, epsilon 2 and epsilon 3 can be set according to the size classification of the pipelines, for example, various pipeline components or pipeline equipment can be divided into a plurality of intervals according to the volume size of the pipeline components or pipeline equipment, the pipeline components and/or pipeline equipment elements in the same interval have the same group of epsilon 1, epsilon 2 and epsilon 3 values, and the epsilon 1, epsilon 2 and epsilon 3 values corresponding to different intervals can be opposite or different.

As some embodiments of the application, the volume of each pipeline component and pipeline equipment in the embedded pipeline in the comprehensive arrangement process of the pipeline is calculated in sequence, each pipeline component and pipeline equipment are divided into 3 intervals according to the volume, wherein the 3 intervals are respectively a first interval with the volume being more than V1, a second interval with the volume being more than or equal to V2 and a third interval with the volume being less than V2, and the value range of V1 is 5-10 m³The value range of V2 is 0.5-2 m³(ii) a The first, second and third intervals correspond to a set of values of ε 1, ε 2 and ε 03, respectively. More preferably, epsilon 11 corresponding to the first interval is larger than epsilon 1 corresponding to the second interval is larger than epsilon 1 corresponding to the third interval; epsilon 2 corresponding to the third interval is larger than epsilon 2 corresponding to the second interval and is larger than epsilon 2 corresponding to the first interval; epsilon 3 corresponding to the third interval is larger than epsilon 3 corresponding to the second interval and is larger than epsilon 3 corresponding to the first interval. Thus, for large-size pipeline equipment and pipeline components, the axial or length direction position deviation has a large influence on the judgment result, the axial or length direction installation accuracy of the large-size pipeline equipment and pipeline components can be improved, and the position change of large-scale related elements is avoided; for small-sized pipeline equipment and pipeline components, the position deviation of the starting point and the end point has larger influence on the judgment result, the position installation precision of the starting point and the end point in the small-sized pipeline equipment and pipeline components can be improved, and the passive change of the later indoor decoration design caused by the overlarge position deviation of the two ends of the small-sized pipeline equipment and pipeline components is avoided.

Further, in the step S345, when the comparison result is consistent, and a construction correctness indication is sent, the value of the counter N is cleared.

Further, in the step S5, Nmax is a preset threshold, and the value of Nmax can be set according to needs, such as Nmax is 3.

Further, in the step S6, when the pipeline still cannot be installed to the design position after the constructor repeatedly confirms and adjusts the pipeline, a communication request is sent to the designer, and after the designer receives the communication request, the process may continue to execute the step S7.

Further, in step S7, when the constructor communicates with the designer, the constructor may show the site condition to the designer through a camera, and the designer may import the comparison component of the pipeline in the BIM model according to the current actual position information through the actual position information of the current embedded pipeline, where the comparison component has information consistent with the shape, size, and the like of the current embedded pipeline, but has a three-dimensional spatial position consistent with the actual position information, and then guides the constructor to perform the site adjustment according to the site condition, the deviation between the comparison component and the design component in the BIM design model, and after the adjustment is completed, the constructor modifies and updates the BIM model according to the communicated construction requirements, and performs the construction according to the communicated construction requirements.

Generally, after repeated adjustment, construction workers still cannot meet design requirements for two main reasons, one is that construction workers wrongly interpret the design requirements, so that construction errors are caused; the other is that the construction cannot be carried out according to the design requirement due to the change of the construction working condition, and the design change is required. After the communication between the constructors and the designers, if the design requirements of the constructors are wrongly read, the constructors can explain the design requirements to the constructors and then construct according to the design requirements; if the construction cannot be carried out according to the design requirements due to the change of the construction working condition, the designer can carry out appropriate modification and updating on the BIM design model according to the current construction working condition, and then the constructor carries out construction according to the modified BIM design model.

Of course, in step S7, the constructor may be a specific constructor, a construction manager, or the like.

Further, in the step S7, when the designer needs to modify and update the BIM design model appropriately according to the current construction condition, the modification reason and the modifier should be added in the BIM design model. Of course, the designer can directly modify the minor modification with a small influence range and note the reason for the modification, and the designer needs to modify the major modification with a large influence range and review the major modification again to be implemented later.

Further, in the step S7, after the BIM design model is modified, the step S1 is executed again to update the BIM design model based on the step S1. And simultaneously, directly entering step S3, comparing the actual position and the designed position of the embedded pipeline again, and judging whether the construction is correct.
