3D Laser Scanning Services

The most important aspect in any major architectural/construction project is meticulous and detailed mapping, planning and constant comparison during construction of defined design and actual construction. BIM, also known as Building Information Modelling provides an effective approach to meet the construction requirements from the initial stages of designing right up to the onsite construction. Advanced technology of 3D lasers scanning has been recognised by architects, building engineers and peers in the field as a major breakthrough in modern times, which has found its use at all stages of construction work. 3D scans of small building to complex structures can be created with Laser scanners starting from a single structure to a mega city.

Key benefits of using laser scanner in BIM :

• Saving precious time, cost and resources
• Swift and secure way of communication, collaboration, monitoring and problem solving
• 3D documentation at each stage of construction for easy comparison/problem solving
• 3D modelling and as-built digital documentation of facility
• Reduces wastages and costs
• Reduced risk and chances of reconstruction
• It captures real world information into the digital world to deliver information that can be used to analyse, collaboration and execute better decisions to improve and maintain the overall projects and product quality

Oil and gas terminals are some of the most expensive sites for construction work. Every second that a pipe is under specified capacity costs money, so the time that they are offline due to building work needs to be as short as possible. Engineering drawings are only as good as the data used to create them, so if the models are inaccurate, incomplete or non-existent, clashes and rework can lead to production losses

Our Advantages

• Accuracy : 3D measurement of facilities, equipment, and site features can be measured with an extremely high degree of accuracy, much better than manual measurements
• High-Definition Colour Images : Scanning deliverables include an active 3D colour photo of the project site, with picture resolution up to 12 megapixels
• Speed : Scanning will capture 2 Million Pts. This translates to capturing a high volume of information in a single trip to the project site
• Safety : Scanning existing building or equipment features can be done from a safe distance using Class 1 (eye-safe) laser technology
• Accelerate Project Schedule : Collecting accurate field data is the first step for many projects. Scanning allows for the collection of billions of data points in a matter of hours or days versus weeks
• As-Built Conditions : Scanning existing facilities will accurately locate and measure all features of your building, utilities, and manufacturing equipment. Information from the scan is then used to create AutoCAD backgrounds for building and process documentation, or 3D colour pictures for coordination with plant personnel. In addition, the colour scan imagery can be integrated into a virtual training program helping personnel to quickly become familiar with the plant machinery, and general surroundings
• Interference Reduction : The use of scanning technology allows engineers to build a 3D model over the scan data and better identify interference points with new equipment

Where access is restricted and areas are unsafe, laser scanning is the best solution to capture with detailed precision the as-built data from a safe distance. Unlike conventional methods, that capture specific individual points one at the time, laser scanning captures millions of points per second with rich details of the entire scene, just like a camera taking a 360-degree photo, but with an accurate position for every pixel.

Power plant stations need the latest maintenance, safety and documentation to ensure the generation of electric power. Given their importance, power stations, nor the users dependant on their energy supply, can afford delays or malfunctions.

Laser scanning is a great tool to faster document the as-built conditions for any environment helping to manage existing systems during the design, construction and maintenance cycles. Plant documentation of the existing structures using 3D models enables engineers and surveyors to :

• Create valuable models for planning, fabrication, and clash detection when integrating new equipment
• Minimize plant maintenance and field work rework and delays
• Find equipment failures or malfunctions
• Guarantee installations comply with safety regulations reducing risks and costs
• Recognise breakdowns to support insurance claims
• Plan more efficient plant layouts with verified measurements for maintenance or virtual fit ups

Digitalisation approaches are the key to drive effective transformation in the power plant by aligning people, processes and technology. The 2D drawings, 3D solid models, volume calculations. measurements and videos, as well as many other assets laser scanning can deliver, provide an accurate smooth map of any power and plant environment.

India being a more than 5000 years old country has a plethora of cultural and historical building structures. However, we have only 2D maps available from PWD for buildings that too only for the buildings that came up in the last century or so. Most of Historical monuments/buildings do not even have any such records.

3D scanning of the buildings provides the actual view inside the building, doors, passages and entry/exit points. The historical/heritage building once damaged due to natural decay or manmade catastrophes cannot be reconstructed to its original shape/glory unless its 3D scan is available. Because the obvious advantages of laser scanning like: non contact measurement, high accuracy, long range, fast data acquisition etc. Other disciplines like cultural heritage, architecture, urban development, forensics and the entertainment industry are starting to steadily adopt this technology and store 3D scans of each and every monument/heritage buildings.

How does 3D laser scanning work for heritage conservation?

• Takes minimum time to acquire huge data
• Handling and sharing of data to multiple users and very easy to handle
• Very cost effective
• Fast, accurate and reliable virtual copy creation
• Highly accurate information and 3D documentation
• Complex structure 3D imaging and modelling with fingertips

The major issues faced by large scale manufacturing units includes the issue of revamping, upgrading, maintenance or replacement of major or minor portions of the plant machinery. The 3D scans created of the plant and machinery help the management to revisit their plant in its original form with highly accurate measurements. In case of accident/natural disaster etc. wherein repairs to a specific part is to be undertaken the 3D scans play a vital role by helping to replicate a portion or whole of the plant machinery to its original shape. This helps save on time, resources and expenses, thus the reconstruction takes minimum of time and production can begin much earlier as compared to the usage of conventional processes and methods.

The 3D laser scanners provide highly accurate three dimensional digital documentations in few minutes for accurate original displacements. This provides for most accurate reconstructions plans.

• This may be termed as reverse reconstruction
• Fast and economical as 3D scans with latest scanners provide original & accurate layouts
• Precise reconstruction with speed
• Replace conventional cumbersome processes like physical tape measures, photography, 2D sketches, range finders etc
