Using Handheld Lidar Scanners for BIM

Many A & E firms use laser scanning at the beginning of a project to document existing conditions and start their renovation designs—but what if construction teams could gather laser scan quality data weekly, or even daily, to track construction progress and avoid mistakes?

If you’ve ever had the pleasure of using a terrestrial laser scanner you know two things: the information you get is rich, but the setup and actual operation is a royal pain. What if you could get the same quality data without all the hassle? 

Scanning frequently and aligning the point clouds to a BIM design gives construction teams the opportunity to ensure that what’s being built matches the BIM—not after but—during construction. Mistakes can be completely avoided or caught early on to prevent costly rework and delays.

Even with firms who've adopted BIM and implemented thorough pre-construction processes, it seems that 2D paper shop drawings still dominate the field and trailers. We love and encourage the adoption of digital shop drawing apps like PlanGrid, BluVue, & 360 Glue, and while these are a step in the right direction, the process of translating 2D sketches back into 3D gives way to information loss and mistakes.

It’s mind blowing that architects and engineers put so much effort into a BIM design but when it’s time to build, the plans revert to 2D and become subject to human error. The BIM design takes a back seat during the most critical phase of actualising a new building, the construction itself. How do you get effective quality control from this?

Paracosm is building a solution that will bring construction teams into the digital age and put necessary checks in place to empower project managers and everyone involved in a construction project to be proactive about problems instead of reactive.

Scanning daily or even weekly also makes it easy for construction teams to send progress reports to building owners and deliver better as-builts at the end of a project.

You’d think that with more data comes more responsibility (and no one wants to add more work to a project) but we’re working on creating a system that’s simple to use and even less time consuming than a regular walkthrough.
