Technology Showcase: Tilt Walls

Tilt wall construction features a series of concrete panels that are created on the job site using wooden forms, rebar, and concrete. The wooden forms are shaped and rebar is cut to match the final design of the panel. Concrete is then poured into the forms, cured, and finished. From there, the concrete panels are tilted up into place to form a building’s exterior wall.


The RIEGL VZ-400i terrestrial laser scanner was utilized during the process of the tile wall construction to help verify that the wooden forms for the walls were correct before the concrete was poured. This proved beneficial when the laser scan data was compared to the models created for the forms. It was seen that a few of the wooden forms were incorrect and off by a few inches. 


By utilizing LiDAR data and catching the measurement error before the concrete was poured, time and money was immediately saved. If the concrete had poured and the error discovered when the tilt walls were being placed, it would have delayed the placement of the walls while waiting for another wall to be shaped, poured, cured, and lifted. It additionally would have cost more money to have to take down the wall and rebuild a new one, plus pay the laborers and contractors to redo the tilt wall panels that were incorrect.


Being able to adjust the tilt wall framing quickly and efficiently, thanks to LiDAR data, is helping to keep the project on schedule and at budget.
