POINT CLOUD TO BIM SERVICES

The use of a point cloud to BIM services is an effective solution in the design of all architectural and engineering elements of a building. This technology is useful for designers, architects, builders and other professionals. The development of a BIM model based on a point cloud bim allows you to effectively and conveniently correlate existing building structures with the designed ones, as well as create topographic information maps during reconstruction, restoration and modernization of an object.

ROSECO carries out a full cycle of point cloud services - from 3D scanning and / or photogrammetry of an object, processing the received data to create a point cloud to integrated design and development of BIM models for the needs of the Customer.

Benefits of using point cloud to BIM services

A point cloud is a large amount of data about a physical object, obtained by laser scanning or photogrammetry, and allows you to create three-dimensional representations.

Point cloud files provide high detail of both internal and external elements of a construction site and / or territory such as a digital impression of architectural forms, engineering systems, accurate recording of all deformations etc.

The point cloud BIM allows users to optimize the design process, quickly make adjustments and get the most accurate information about the technical condition of the construction site.

This technology is usually used in the tasks of reconstruction, restoration or technical re-equipment of enterprises. Point Cloud data is used for subsequent design and development of BIM models. At the same time, the data array can be presented in both 2D and 3D formats.

Key benefits of creating point cloud to BIM services:

A detailed floor plan and comprehensive data on the geometry of the building object, its facades, etc.
Possibility of using point cloud to BIM to quickly track and correct collisions.
A clear and detailed 3D-representation of the object, allowing users to make informed decisions in BIM design.
Point Cloud + 4D BIM is used during construction to track every stage of work.
Point Cloud + 5D BIM allows efficiently budget and plan project costs.
Point Cloud + 6D BIM is used to optimize resilience.
Point Cloud + 7D BIM is used for efficient building management during its operation (condition monitoring, repair and maintenance, renovation, etc.).
Remote measurements. Point cloud data allows users to gather the dimensions of any element without visiting the object. This is especially true when working with hard-to-reach places of building structures.
Allows users accurately calculate the parameters for the safe demolition of the building.
Ability to develop the most accurate BIM model based on point cloud data.
Minimization human factors related risks during work.
Ensuring maximum return on investment and minimizing financial risks.
Detailed information regarding the technical condition of the building, the presence of defects, deformations and deviations from the data specified in the design documentation.*

* If necessary, it is possible to perform a series of scans / surveys and track the behavior and development of deformations over time.

Point cloud technologies

A point cloud is a collection of geometric data that consists of an array of points in a three-dimensional coordinate system. These points are specified by coordinates X, Y, Z and define the geometric surface of the object inside and outside.

Point cloud files can be integrated into design drawings using them as reference points. This allows users significantly reduce the design time and at the same time avoid errors associated with the human factor. If necessary, it is possible to insert additional models into such drawings.

Today, the main technologies for obtaining point cloud files are:

Fig. 1. Laser 3D scanning of the Soviet orbital spacecraft-rocket plane "Buran" (project ROSEСO).

Laser scanning is 3D scanning of buildings and structures inside and outside using specialized scanners of different ranges. An example is Figure 1.

Photogrammetry is a technology of space, aerial and ground imagery, which, when processed, allows to obtain an orthogonal projection with photorealistic structures. An example is fig. 2

Laser scanning and photogrammetry comparison methods

Data retrieval method	3D laser scanning	Photogrammetry
Field work time	Longer fieldwork time	Less fieldwork time
Accuracy	Accuracy in absolute terms	Accuracy in relative terms
Dimensions of measured objects (order)	1…300 m	0.01…10000 m
Object shape	Doesn’t affect the quality of the result	«Doesn’t like» corners and sharp drops in depths, littered objects

Photogrammetry method is always available whereas with 3D laser scanning method sometimes difficulties occur during instrument installation (3D lazer scanner) stage. In cases where there is no sufficient access to the object, it is possible to combine the results of photogrammetry and laser scanning into a single point cloud.

After completing scanning and / or surveying the object, specialists process the obtained material and create a 3D representation of the object's point cloud for subsequent design and development of BIM models.

Point cloud modeling services with ROSECO

ROSECO provides point cloud modeling services using laser scanning and photogrammetry methods for objects of various complexity levels. At the client's request ROSECO provides project development services and digital BIM models creation. Quality control is also carried out at all stages of project life cycle.

Today ROSEСO is the BIM leader according to Autodesk. In 2020, our company won the BIM & Security award in the Best Detail category with the Multifunctional Medical Center project.
