Methods for Measuring the As-Built Dimensions of Slurry Casing | Accuracy Control of Slurry Casing
Hello, everyone. This is Enta. How do you measure the as-built dimensions of formwork? I generally start by lightly securing the zero point with concrete nails, as shown above. I set these up on both sides and take my measurements. When measuring the as-built dimensions of formwork, I generally measure along the centerline of the formwork…
