Thank you for choosing to work with Multivista. This guidance document outlines Multivista’s 3D Laser Scanning and Scan to Services processes for completing client projects as outlined in our signed proposal agreements.

Multivista are one of the largest 3D Laser Scanning and Scan to Services companies in the world. With 150+ local laser scanning experts, delivering 1000s of projects every year across numerous cities, states, provinces, and countries.

As part of the global company, Hexagon, Multivista operates within the Building Solutions division along side sister companies; Leica Geosystems, AGTEK, Projectmates, OxBlue and Voyansi.

Local Multivista operations teams will work with clients to schedule their site visit(s) to capture all areas previously agreed upon and included in the contracted scope of work. This may include, but not limited to, the scanning of interior spaces, exterior spaces, roofs, mechanical rooms, above ceilings, etc.

To ensure on-site efficiency, it is helpful for clients and facility teams to prepare the project space by:

Multivista does not directly offer licensed surveying services but can work with clients and/or third-party surveying companies to establish and use survey control on site.

Black and white scan targets are placed around the site on vertical, flat surfaces or placed over existing control marks and captured as part of the laser scanning process. The target’s coordinates are then shared with Multivista who will apply the provided Northing, Easting and Elevation (YXZ) coordinate information to the 3D point cloud during the registration process.

This results in the 3D point cloud and subsequent created deliverables, such a 3D BIM model, to be aligned to a specific project coordinate system or a real-world large coordinate system.

Survey control requirements must be specified on the project intake form or scan to services checklist prior to the quoting period as additional costs may be incurred and the coordination of target location and organizing a surveyor must occur before any physical scanning can begin.

After on-site scanning has completed, collected scan data is imported and registered using Leica Cyclone REGISTER 360 software to align, clean and quality check (QC) the data. The amount of time it takes to post-process a scan project is dependent on:

Typically, 1 day of site scanning = 1 day of office processing. Actual processing time may vary. Please discuss precise delivery schedules with your local Multivista sales and operations teams.

The removal or cleaning of ‘noise’ from a point cloud is a standard Multivista processing step. Point cloud ‘noise’ is created typically by the irregular effects that shiny, reflective, glass or wet surfaces have on the laser when it is measuring a surface.

Multivista will endeavour to clean and remove as much ‘noise’ caused by these elements as possible, but some artifacts may remain. Points created by people, vehicles, equipment and debris will not be cleaned by default and will remain within the final delivered point cloud.

All contracted laser scanning projects include hosting of captured imagery/point cloud (colour OR black and white) via the MDS with Leica TruView integration.

Unlimited MDS users can be added for free, and no license or subscription fee is necessary. By default, all Multivista laser scanning projects are hosted for 12 months (starting from the completion of contracted documentation) but can be extended for an additional fee should clients choose. Hosting timelines and costs may vary depending on your contract, please speak to your Multivista sales contact to discuss this further.

The MDS/TruView provides clients and their teams visual access to project sites to enhance conceptualization, collaboration, and transparency. Imagery is measurable and can be easily saved and/or shared amongst colleagues for more in-depth analysis.

After 12 months of included hosting, all MDS projects with TruView will be archived but can be resurrected whenever clients need to revisit project site visuals and information.

The MDS/TruView can be accessed via any standard internet browser (Chrome, Edge, Firefox) and is available on mobile devices.

After scanning deliverables are created, Multivista’s operations teams share their registered point clouds with the dedicated in-house Scan to Services team to create any contracted Scan to Services such as 2D CAD drawings, 3D Revit BIM models, and Floor Flatness Reports.

Multivista’s in-house, dedicated scan to services team is comprised of qualified Architects, Civil Engineers and MEP specialists to ensure a high-quality industry standard. The team utilizes a range of software, including Autodesk AutoCAD, Autodesk Revit and Leica Cyclone 3DR to create drawings, models and reports.

All Scan to Service deliverables are created based on a set of standardized packages that allow Multivista to produce high-quality, cost-effective and repeatable deliverables. Clients must complete the appropriate Scan to Service checklist to define the scope of the project and the cost for creating them. Please be aware, selecting more options will increase the overall delivery/turnaround times as well as cost.

Estimated turnaround times for each Scan to Services project will be relayed to customers at the time of quoting and proposal. Most average sized Scan to Services projects are delivered to clients within 7-15 business days after the registered 3D point cloud is delivered to the Multivista Scan to Services team. Larger more complex projects can take longer.

All 2D CAD drawings will be created based on Multivista’s standard Scan to Plan packages as defined in our Product Definition document. Project variables, such as drawing methodology, coordinate systems and units must be stated prior to project commencement via the Multivista Scan to Plan checklist. Changes to these variables will incur additional fees.

The style, layering and drawing methodology are based on company and industry standards.

If Building Section drawings or Exterior/Interior Elevation drawings are requested, it is asked that clients mark up map images or existing plans to aid in drawing creation.

All 3D Revit models will be created based on Multivista’s standard Scan to BIM packages as defined in our Product Definition document. Project variables, such as modelling methodology, coordinate systems, software version and units must be stated prior to project commencement via the Multivista Scan to BIM checklist. Changes to these variables will incur additional fees.

Multivista has developed a set of standard modelling packages that allow our clients to choose the most suitable deliverables for their Scan to BIM project. Clients can choose from base Architectural elements through to full Mechanical, Electrical and Plumbing systems. These options have been developed in reference to the industry AIA/BIMForum LOD specification but utilize a mixture of graphical Levels of Detail ranging between LOD 200 to 300.

Elements closer to the LOD 200 range include walls, floors, and ceilings. Elements with higher levels of graphical detail and closer to LOD 300 include windows, doors, and MEP.

Floor Flatness reports are a direct analysis of the registered 3D point cloud and created in Leica’s Cyclone 3DR software.

These digital reports display the variations in elevation, or “Flatness” across a floor surface, referred to as a “Heatmap”. Differing floor heights are displayed using an array of colours to make it easy to identify highs and lows within the surface.

If survey control is used during the 3D laser scanning site work, the completed report can also display true elevation/height values to compare against design intent.

It is the client’s responsibility to remove any people, vehicles, equipment or debris from the target area or this will be captured during scanning. Multivista will endeavour to clean and remove this ‘noise’ but some elements may remain and be shown in the final report.

All Floor Flatness heatmap reports are delivered via the MDS platform as .PDF files.

All registered 3D point cloud files and contracted Scan to Services deliverable files will be made available to customers on the MDS. All laser scan and Scan to Services deliverables are paid for and owned by the client and available to download from the MDS as and when required.

Projects and their deliverables will be hosted for 12 months from the start of project completion but can be resurrected and made available for access and download.

Any on site delays that require additional time on site or return trips to complete the work will incur additional costs and will delay the delivery of the finished product. Below are some common causes:

Any changes after contracts have been agreed or after Scan to Services have commenced will incur additional costs and will delay the delivery of the finished product. Below are some common causes:

The Laser Scanning and Scan to Services teams at Multivista look forward to working with clients to ensure all projects are captured and delivered professionally and efficiently.
