A Guide to 3D Laser Scanning Technology

3D laser scanning creates measurable data that allows design engineers and architects to verify as-built conditions remotely. Measurable images can be used to build cloud-based interactive project plans that allow designers to “walk” the job site from within the platform, even stopping to take a detailed look at relevant sections in the plan. Two of the most valuable services Multivista provides for architects and designers are Scan to Plan and Scan to BIM, both of which give unprecedented visibility and insight to users in the design and build phases.

The 3D scans are accurate enough that architects can use them to take measurements remotely from their web browser to cross-reference against the plans.

Perhaps no one gets more from 3D laser scanning than leadership on the ground at the construction site. Contractors, foremen, and other decision makers can use measurable 3D images to direct field teams, document progress, and plan for next steps before crunch time starts.

Contractors who already use a construction tech stack can use integrations to connect the 3D data to their project management software, where it can fill-in valuable measurements for change orders, punch lists, RFIs, submittals, and other essential documents. 3D scan data can also be used to schedule and prep subcontractors to streamline installation for vital systems.

Complex systems require accurate measurements in order to ensure a tight, efficient fit. Many ventilation systems and heating elements need custom-built mechanical components that have to be built off-site before they can be assembled and installed. Without an accurate representation of as-built conditions, contractors rely on blueprints that may not be true to form — and could lead to a costly rebuild.

Instead, mechanical engineers can access 3D imagery of a relevant area with accurate measurements (all without going on-site to collect information). The result is faster turnaround with no wasted trips or expensive adjustments.

For owners and developers, centralizing 3D laser scanning data in a platform like Multivista means keeping all project stakeholders in the loop. Using a secure sharing feature, they can distribute accurate 3D images to connect architects, general contractors, HVAC and utilities teams, other specialty subcontractors, and investors remotely from anywhere.

At a high level, the result is incredible time and resource savings in the form of reduced timelines, risk, and rework. Stakeholders and developers can collaborate on 3D images to manage quality assurance and plan for shifting workflows as the scope of the project changes. On the ground level, it also means ensuring the landscaping team doesn’t show up on the day when the water main is being dug.

Once a project is completed, 3D images are available for facilities teams to expedite service and repairs. Hand off these accurate images to O&M teams or third-party maintenance providers to keep the property in tip top working order.
