Capturing Cross-Sections with the iPhone 17 Pro’s LiDAR | Steps for Cost-Effective Point Cloud Creation on-Site Using Scaniverse and CloudCompare
Hello, everyone. This is Enta. In this post, I’ll share how I used the iPhone 17 Pro’s LiDAR to capture a point cloud and create a cross-sectional diagram—all while keeping costs as low as possible. I’ll walk you through the process and show you the results. Lately, even civil engineers on construction sites have been saying, “I’d like to try point cloud scanning, but…”
Reinforcing Bar Lap Joints | Practical Standards for 45D and L/2 Offset Joints in Slope Construction
Hello, everyone. This is Enta. I’m going to write about “rebar lap splices,” which are a constant feature at slope construction sites. lol When I was just starting out, I used to wonder all the time, “What D-value should I use for the lap length?” and “How much should I offset the splices sideways?” In this post, I’ll share some criteria to help you make decisions without hesitation on the job…
Is It True That “Quiet People Are Good at Their Jobs”? Differences in Performance Based on Personality, as Observed at a Slope Construction Site
Hello, everyone. This is Enta. “He’s quiet, but he gets the job done.” “The quieter someone is, the more trustworthy they are.” These are phrases I hear a lot on the job, lol. On the flip side, there are also quiet people who get on people’s nerves—with comments like, “I have no idea what he’s thinking,” or “Stop keeping quiet and report back.” The same personality can lead to different reactions depending on the workplace…
The Power of Drainage Pipes with Mats | Anti-Suck-Out Material That Prevents Cavitation Inside Slopes
Hello, everyone. This is Enta. Today, I’d like to talk about “Matt-In,” a seepage prevention mat that’s installed in the drainage pipes used in sprayed mortar work. Once the natural rock is cut by a machine, it can never return to its original state. Even if the surface is covered with sprayed mortar, the interior will gradually continue to weather…
How Does Adaptive Capacity Change with Age? Explaining Heat Acclimatization, Cold-Weather Work, and the Introduction of New Construction Methods Based on the Latest Research Papers
Hello, everyone. This is Enta. When you’re working on a slope construction site, I think there are times when you notice that “even under the same conditions, the reactions of young workers and veterans are clearly different.” For example, during mortar spraying in the middle of summer, the younger workers tend to get exhausted first, whereas during rope work in the winter, the hands of the older workers…
What Is "Kan'ko"? | A Civil Engineer Explains the Pronunciation, Meaning, and "Risk-Taking" in Construction Sites
Hello, everyone. This is Enta. “Carry out” and “willingness to carry out”—we see these terms quite often in the news and safety documents, but aren’t they among those words that, to be honest, you can’t answer right away if someone asks you what they mean? Especially on construction sites, the term “willingness to carry out risky tasks” comes up as part of KY activities. Well…
Key Points for Installing Self-Drilling Rock Bolts | Q&A on Drilling and Grouting to Avoid Confusion on Site
Hello, everyone. This is Enta. Today, I’m going to summarize the key points of self-drilling rock bolt installation in a Q&A format. I feel that self-drilling rock bolts are a method where “the more experience a contractor has with them, the more cautious they become.” At first glance, it seems simple—drilling, grouting, measuring…
The Argument Against Using Aluminum Caps for Rebar Insertion | 8 Reasons to Reevaluate NEXCO Specifications
Hello, everyone. This is Enta. The other day, at a slope construction site not contracted by NEXCO, I noticed that the rebar insertion tools weren’t fitted with caps at the ends. I thought, “Oh, so we’ve finally gotten this far,” so I’m going to write another post that’ll probably make the material manufacturers hate me lol. To cut to the chase…
The Key to Safety on the Job Site Is Your Body! Understand Heat Stroke Alerts Correctly for an Accident-Free Summer
Did You Know? Heat Stroke Alerts and Their Background In recent years, due to extreme heat and tropical nights, the number of people hospitalized for heat stroke has exceeded tens of thousands annually. There is a risk of heat stroke even indoors, and the situation is serious—last year, the number of hospitalizations reached a record high. To protect yourself from this life-threatening heat…
