Since laser scanning is speedier than conventional mapping techniques, it has the advantages of providing instant information, improving accuracy and quality, and assisting in cost reduction. On a construction site, laser scanning also improves decision-making by streamlining coordination.  The laser used to collect precise information for every aspect of a construction site is known as laser scanning or high-definition surveying.

Common Challenges of Construction Renovation:

Just as the new buildings face several construction challenges, renovations also involve unique challenges. Some of these include:

  • Uninterrupted facility operations including manufacturing units, healthcare, airports, etc.
  • Damage to complex architectural projects like historical monuments.
  • Major time, cost & resource drain with frequent site visits for dimensions & layout assessment.

Solution through BIM Laser Scanning:

  • BIM laser scanning ensures building project owners an accurate, hassle-free and safe renovation.             

Benefits of Laser Scanning in Construction:

  • Improved visualization with accurate scan to BIM models – Scan-to-BIM enables architects and engineers to create information-rich images of a physical object or building. This becomes inaccurate and time-consuming if measured by hand. The coordinated 3D BIM model enables AEC stakeholders to visualize, identify and resolve clashes and suggest modifications to renovation plans.
  • Prevention of delay with Information-rich BIM models – 3D BIM models converted from laser scans are comprehensive with information about color, building reflectivity and other details. The granular information facilitates architects and engineers in understanding exact material properties. Since it is easy to integrate, model and assess point clouds, stakeholders can instantly use the information about the existing structure. This minimizes the requirement for RFIs and reduces cost and time overrun.
  • Building intelligent design models from point cloud data – High-definition laser scan to BIM services could be successfully leveraged by project stakeholders for creating intelligent design models through as-built conditions based on 3D point cloud data. Components like structural beams, columns, slabs, fixtures, roofs, pipes, etc. are accurately modeled by BIM engineering firms to make informed decisions about retrofitting, replacement, and facility maintenance.
  • Renovation from a safe distance – Precise and comprehensive Revit 3D BIM models enable AEC clients to explore building systems, without visiting a site physically. This facilitates understanding challenges that provide a significant head start. Stating from a safety and health perspective, it enables building professionals to detect onsite hazards and execute onsite installations in a controlled setup.
  • Creating realistic proposals with building analysis – Point clouds to mesh models aid architects, general contractors as well as cost estimators to create a realistic budget based on detailed building analysis. Practical proposals need high accuracy, letting stakeholders stick to their budgets, instead of experiencing a budget blowout. Using solid point cloud data, stakeholders recommend realistic cost calculations for renovations and retrofitting. Converting laser scan to BIM model has transformed building analysis. Earlier a building erected for renovation requires a significant amount of time. Prevalence of issues in the previous design deteriorated building components that were not visible during surveying and had to be unearthed during actual demolition. However, this technique has changed with laser scanning. All critical issues of building components are identified during the scanning process and are analyzed completely before renovation.
  • Better construction decision-making at the design-build phase – During this construction phase, laser scanning helps designers to comprehend the site conditions aptly with the help of an as-built model of the construction site and the adjacent buildings, facilitating better design decisions.
  • Identifying discrepancies during the construction stage – At the time of construction, a laser scan to BIM identifies design discrepancies between as-built and as-designed models. This helps to compare the tolerance values as per building codes and guidelines. Construction safety management and digital reproduction are also considered during the construction phase.
  • Virtual installation through accurate as-built BIM model – Laser scanning also helps virtual installation and assemblies through accurate as-built BIM models, enabling scan to BIM solution to determine flaws before installation.
  • Construction safety management – Scan to the BIM model is also a great recourse to improve construction safety management, detecting hazards, and identifying ways of ensuring safety.
  • Digital reproduction of design for renovation – Manual and ambiguous drawings get replaced by scan to BIM models providing a detailed digital 3D model. Further, this technique is responsible for visualizing designs and modifying them.
  • Saving of survey time – Adopting the laser scan technique helps AEC professionals to save a lot of time in surveying old building and existing site that needs renovation. It is always good if a survey company invests in competent laser scanning equipment and scans the building in different phases. This is not much tough as one easily works with a few technicians onsite for taking measurements. 3D laser scanning decreases an overall cost and effort by 40% helping you capture the components and their 3D geometry using laser beams that can later be converted into scan images, reducing field time to a great extent.
  • Accuracy of Deliverables: Accurate data collection is one of the most significant advantages of using laser scanning services. If the method of data collection is accurate, conversion of the scan to BIM models will surely give positive results. A conventional survey has never guaranteed accurate results as it depends to a great extent on the technician’s understanding, evaluation and other factors. Using scanning to great extent improves the accuracy of criteria along with the visibility of deep building components like beams and pipes.
  • Seamless Collaboration amongst team: Scan to BIM Services is extremely useful in establishing relationships amongst design engineers, architects, building contractors and end-users. Developing 3D Models from scan enables AEC professionals to comprehend existing building designs and discuss proposed design alternatives. As a result, it becomes easier to comprehend design errors and update the new proposed design. BIM Engineers can easily integrate Architectural, Structural and MEP models created from scans into a coordinated 3D model for detecting threats, interference, and design issues in an existing structure.
  • Enhanced design documentation during facility management stage – Advantages of the scan to BIM Modeling are also perceived during the building facility operations and facility management stages. Using laser scan to BIM technology AEC professionals get improved design documentation and functionality. A fundamental application of Scan to BIM Services is complex geometries together with building texture. Moreover, there is a performance analysis of the building to enhance building performance, energy consumption, and structural reliability.
  • Reducing the overall cost of operation: Laser scan to BIM modeling facilitates decreasing the overall cost of survey and construction. Conventional survey techniques are costly and time-consuming compared to laser scan surveying. Considering the aspect of as-built modeling, BIM point cloud modeling services have already proved to be a savior for construction planning and budget estimation. Virtual construction modeling through BIM has helped to reduce errors and detect issues at the pre-construction stage, leading to decreased overall construction cost. LiDAR laser scanner is one such instance that helps to scan buildings compared to a technician.
