Here's how to calculate quantities for formwork in on-site spray-applied concrete construction.
Hello, everyone. This is Enta. You’re working on formwork construction, right? Do you know how to calculate the vegetation work and mortar spraying inside the formwork? The reason I’m bringing this up is that at a certain job site, there was a consultant doing something really unusual when it came to calculating the formwork dimensions. CAD…
Methods and Principles for Measuring Drill Hole Length
Hello, everyone. This is Enta. Since quite a few people seem confused about the concept of drilling length, I’d like to explain it. Let’s start with the basics. Drilling length refers to the length of the drilled hole. So why is measuring drilling length so confusing? It’s because of the remaining length…
Cement slurry is carefully controlled using flow meters | Quality Control
Hello, everyone. This is Enta. When performing rebar insertion or ground anchor work, you inject grout, right? I imagine you sometimes use a flow meter to monitor that process. Companies like NEXCO use them quite a bit, don’t they? So, what exactly is a flow meter? As the name suggests, it measures flow rate. …
How Do You Use That Jig?! | Practical Guide
Hello, everyone. It’s Enta. I’m going to answer a question I’ve been getting a lot lately lol. People keep asking, “What is this thing you’ve been making a lot lately??” This is a jig for using bolt scales on flat caps. This is it. Flat…
The Loss Rate Has No Impact on the Market Unit Price for Empty Bag Inspection | Cost Estimation
Hello, everyone. This is Enta. Lately, I’ve been getting asked a lot, “How do you handle the inspection of empty bags?” Back in the day, there used to be something called the “waste rate.” Well, it still exists today, lol. In our construction work, the first thing we prioritize is the design documents. These are the design documents you’re probably familiar with. …
Is This the Age of Processed Steel? | Trends in Materials
Hello, everyone. This is Enta. There’s only one month left in the year! Let’s stay focused! The other day, I was doing some research on spacers. It turns out that spacers for slope surfaces were originally designed for thickness control. They’re still used for that purpose today…
Tools for the Next Generation | Passing on the Construction Trade
Hello, everyone. This is Enta. Are you working on formwork? For me, this is the one thing I really don’t want to do when managing formwork, lol. Measuring the center-to-center spacing of the forms. Let’s say there’s a 1,000-meter stretch of formwork. Suppose you’re measuring the center-to-center spacing during assembly. How many spots do you guys…
All Construction Photos Serve as Evidence | The Importance of Documentation
Hello, everyone. This is Enta. I recommend taking a photo like this just in case. Can you see it? lol I’m measuring the height of the spacer. Since the spacer itself is treated as a miscellaneous expense now that we’re using market unit prices, it’s fine whether it’s there or not. The drawing…
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…
