Material Quantity Calculations for Formwork Construction | A Complete Guide to Calculating Quantities of Lath, Wire Mesh, Rebar, Formwork, Anchors, Mortar, and Sand Using Sample Calculations
Hello, everyone. This is Enta. A while back, I went on and on for seven posts—from “Part 1” to “Part 7”—explaining how to calculate materials for formwork. lol The series covered: reinforcing mesh, vertical beams, horizontal beams, formwork, anchors, cement, and sand. Even though I wrote it myself, halfway through…
Excel Quirks | Why Calculation Results Drift Due to Accumulated Fractional Places, and a Look at IEEE 754
Hello, everyone. This is Enta. Have you ever set up a quantity calculation in Excel only to find that “when you add everything up, there’s a 1-yen discrepancy compared to your manual calculation”? Even when estimating costs for slope construction—where you apply formulas like area × unit price × consumption tax—there’s always a discrepancy of 1 yen or 1 m² in the final row. This…
When calculating the number of scaffolding workers at heights, the count starts from the bottom and works its way up!
Hello, everyone. This is Enta. Today, I’d like to talk about billing for scaffolding work. Scaffolding is often required when ground anchors or rebar inserts are installed at the top of a slope, isn’t it? For example, suppose there were ground anchors or rebar inserts in a location like the one shown below…
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…
Important Things to Keep in Mind Before Starting Construction
Hello, everyone. This is Enta. I’ve been in Tokyo for a few days now, lol. Between handling arrangements for this company and other stuff, I’ve been walking so much in Tokyo that I feel like I’ve lost weight—or is it just me? Anyway… An important task for a construction manager before starting a project: First, reviewing the design documents…
About the "Zabuton" Budget (Part 2) | Detailed Cost Estimation
Hello, everyone. It’s Enta here. I’ve been in Niigata for a few days now. It really is a bit chilly here. The cedar pollen is a little better than in the Tokai region, though. It’s a bit of a relief, lol. Anyway, back to the topic at hand—I’ll talk a little more about money in the “Zabuton” segment. I’ll keep going just a little longer, lol. That said…
How Drainage Pipes and Drainage Concrete Change the Area | Kagoshima Business Trip
Hello, everyone. This is Enta. Today, a piece of machinery left our company bound for Kagoshima. We’ll be away for a little while, so thank you for your continued support. But enough of that. The change in area caused by drainage pipes and drainage concrete—that’s common knowledge for anyone in the slope stabilization business, right? Drainage…
