Things to know for better Point Cloud Scanning and the realities of Point Cloud Modeling in the AEC industry

The demand for 3D laser scanning continues to grow in the AEC industry. The adoption of Point Cloud Scanning by engineering firms for various new and existing projects has shown significant time savings and profits for owners and stakeholders. Designers and contractors continue to see the value for their ability to deliver exceptional accuracy and a data-driven approach towards “proactive project management”. The construction sector has witnessed heavy pitfalls through the entire lifecycle of the project and greater ones upon completion as well.  

With Scan to BIM services, owners and stakeholders can leverage clear communication and visualization on what was required and what has been built on-site. BIM has proved to be a principal driver for the demand of Point Cloud Modeling. Most of the states in the US have seen a very high rate of adoption for Building Information Modeling.

Thanks to modern BIM software like Revit, designers and general contractors can evaluate clashes through virtual coordination. It’s always client perception of how much the entire process will cost. It’s better not to tell them the cost, but educate them about the entire process and the kind of profits Point Cloud Scanning would yield in the long run.

The steps would include – the explanation of field work, brief introduction on Point Clouds, analyzing the data, using point cloud data in BIM software, building a 3D model and the final process of 3D coordination.

Huge point clouds require BIM authoring software like Autodesk Revit and Navisworks to use Point Cloud data.

Point Cloud

3D Laser Scanning creates a raw data output in a point cloud format. Point clouds generated by the scanners create high-visualization for the purpose of reference for onsite workers and professionals. These point clouds are a set of points in the 3D coordinate system. The point cloud data needs to be converted into software adaptable data through direct, parametric modeling and mesh-based modeling.

How do you bring about Point Cloud data to Point Cloud Modeling in BIM?

Scanning is just one part of the process; it must be integrated into the BIM workflow as well to support the entire construction process. These 3D scans can be used for Quality Assurance in partially built infrastructure.          Engineers and designers need software like Revit and Navisworks to manage point cloud data and provide Scan to BIM services for clients and owners.  In terms of Proactive Project Management or QA, these point cloud scans help general contractors and QA engineers to actually go onsite and compare point-cloud data against intended design.

Point Cloud Modeling comprises of three crucial components viz. Scanning and surveying, registration, and the conversion of models to 3D systems. This raw format is then converted to various file formats viz.. pts, .rcs, etc. This raw data can be accessed by BIM authoring software like ArchiCAD, Revit, Navisworks, etc.

What’s the reason behind companies opting for Point Cloud Scanning?

Bigger time savings on surveying

Scan to BIM services can save on time and cost for surveying new and existing buildings. A single Point Cloud technician can handle complex projects with the help of good laser equipment, and this can reduce surveying cost and efforts by at least 35% in totality.

Precision results

It is highly imperative for owners and stakeholders to know what has been built and what are the actual requirements of the end-product or deliverables. The accuracy of a Point Cloud Scanning provides users with the power to analyze models and a partially existing structure to make sure all the elements are kept in place.

Easy Renovation

Design assessment for building renovations has become extremely effective whilst using Scan to BIM Services. For existing structures that need renovation, but are occupied, 3D laser scanning provides an easy solution to scan the entire building without disrupting the lifestyle of occupants inside the building or infrastructure. New models can be designed as an extension of the old design wherein old reference data can be compared to check clashes or problems in the new design.

Team Collaboration

Scan to BIM services are extremely useful in close team collaboration wherein people from various trades can assess the 3D model and understand design flaws based on old designs and the proposed design. BIM engineers can integrate models from all the trades viz. Architecture, Structure, MEP and FP and put it into a federated model to identify clashes, threats, and design faults in the building.

Reduced Costs  

Point Cloud Modeling reduces overall construction and surveying costs as legacy surveying methods and technology had proved to be extremely expensive elevating costs beyond normal margins for owners and stakeholders. The most crucial part of Scan to BIM services is its ability to detect errors early on in the project lifecycle that creates heavy project profits.

Final Words  

Building Information Modeling has pushed the limits of Point Cloud Scanning to another level wherein it has become extremely simple for designers, architects, general contractors, owners and stakeholders to visualize every piece of the puzzle with superior clarity to make informed decisions based on 3D models.

Reasons Point Cloud Scanning in Construction Improves Model And Project Quality

Point Cloud Scanning Services has been termed as the next big thing in the AEC industry.  It has the ability to accurately capture, measure, and anticipate complex structures in 3D ecosystems. Point Cloud Services are used by building companies and owners to create pixel-perfect models through millions of data points, that are processed by software to create a 3D model of the scan. Point Cloud Scanning uses devices such as laser scanners to measure accuracy up to a few mm. Professional teams can convert scanned data into readable or intelligent BIM files through software like Microstation and Autodesk Revit. It allows teams to achieve industrial surveys, monumental preservations, and BIM tasks. Many points make a whole as scans are taken from multiple locations to get a holistic view of the location or area of interest. A software can import point cloud data, and it can be rendered, worked-upon, and edited to suit project needs and requirements. Owners can analyze and model through point cloud data management.

Following are the advantages of Scan to BIM services using the Point Cloud

Extremely Precise

Laser scanning or Point Cloud technology has proved to be a highly accurate tool for engineers and architects to provide detailed information about a physical structure with an accuracy of a millimeter or two. Point cloud scanning services include 2D floor plans, sections, and elevations,3D surface reconstruction, renovating an existing structure, and producing information affluent 3D models for AEC industry, and MEP requirements as well. This involves true dimensions to be captured in real-time to avoid clash detection and mitigate various vulnerabilities during onsite construction.

Level of Detail(LOD)

If the project is up for renovation, then the LOD must be accurately specified for point cloud professionals to understand the complexity of the project, and what level of point cloud density is required. If there are MEP elements, then point cloud technology can provide detailed models with precise laser scans.

Attention to Model Intricacy

A laser scan holds comprehensive information about the physical object in real-time. Real-time would mean absolute precision on color and reflectivity through various points and objects. The importance of color and reflectivity is extremely helpful for engineers to create duplicate objects through exact material compositions of the existing project.

Clash-free Models

Another benefit of Point Cloud Modeling lies in the fact that tolerances need to be setup for errors, camera angles, etc. This needs to be discussed with architects or scanning professionals before scanning starts. 3D architecture and MEP modeling requires exceptional point cloud accuracy and experience for spatial relationships and structural elements. State-of-the-art software can export import and export data, making it a two way process to design accurate, installation ready clash free models.

Exceptional Time Management  

If a team of workers were to take physical measurements of a structure, it would take months to complete the measurement process. Point Cloud Scanning Services create a non-intrusive technique to take measurements for various structures like residence projects, commercial infrastructure, hospitals, schools, and more. There is no chance of damage or even closure of institutions to perform point cloud scanning. Once the scanning is complete, contractors can identify project data, and create exceptional time management schedules to begin actual work.  

Long Term Benefits

Point cloud scanning can be an expensive proposition at the start, but its long term benefits are exceptional. The idea of using laser systems can save a lot of money through quick project turnaround times. Point cloud services  save time on manual measurements,  workforce costs, and it is much safer as well.  Onsite disputes can be mitigated completely using Point Cloud Scanning.

Conclude on a positive note

Various automated systems are deployed to create modeling easier and efficient. The process of Point Cloud Scanning completely mitigates human error, and saves time and money. Geospatial technology can be used for significant project flexibility and productivity. Point Cloud Services automate processes at all levels of the building process viz. classification routines, modeling through precise information, and more.
