Controlling Water on Slopes | Steps to Reduce Flow Velocity and Disperse Water: What Young Project Managers Should Know
Hello, everyone. It’s Enta here. Lately, I’ve been thinking nonstop about how to quickly lower my core body temperature. I figure it’ll help prevent heatstroke. A lot has happened, so I’ll write about that another time lol. But anyway, this time I want to talk about “water.” Working on slopes is, well…
Why Unit Prices for Ground Anchor Drilling Vary So Much Depending on Soil Conditions | How Cost Estimation Works and Quotations
Hello, everyone. This is Enta. A while back, a young site supervisor from another company asked me, “Do you pay attention to the soil conditions when drilling holes for ground anchors?” (Well, you better pay a lot of attention to them, lol.) If you underestimate the soil conditions when preparing a cost estimate, you’ll be the one crying about it later. But anyway…
Are ICT Slope Construction Methods Really Practical on Site? | Considering 3D Surveying and As-Built Management from a Hands-On Perspective
Hello, everyone. This is Enta. In recent years, the construction industry has been flooded with buzzwords like ICT, DX, AI, and 3D data, hasn’t it? To be honest, I think a lot of people working on-site wonder, “Can we really use that on a slope?” Well, the foreman is…
[2026 Edition] Drilling Machines and Drilling Methods for Slope Anchoring | A Guide to Choosing a Drilling Machine, Revised for the First Time in 9.5 Years
Hello, everyone. This is Enta. I’ve had the chance to look back at some of my old posts recently. The article I wrote in 2016, “Drilling Machines and Methods for Slope Anchoring,” was actually published nine and a half years ago. When I reread it, I found myself thinking, “Well, that’s how it was back then, but things are different now…”…
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…
Let's Talk About Collapse Prevention Measures During Construction! (Part 2)
Hello, everyone. This is Enta. This is a continuation of my previous post. “Slope Collapse During Construction: Water Is Almost Always the Cause (Part 1)” In Part 1, I wrote about how the safety factor (Fs) does not reach 1.2 during construction, how water tends to concentrate on the weakest points, and how sheet protection is only a temporary measure…
Let's Talk About Slope Stabilization Measures During Construction! (Part 1)
Hello, everyone. This is Enta. A slope collapses during construction. Every slope contractor has had that moment of panic or disappointment at least once, right? This time, I thought I’d write about the causes and countermeasures for that lol. There are basically only three types of slope sites. Slope sites…
A pay stub from 30 years ago for a slope construction supervisor!
Hello, everyone. This is Enta. The other day, while I was organizing some papers, I actually came across some old pay stubs from my time at a major corporation. Now 50 years old, I found myself thinking about all sorts of things as I looked over the stubs from when I was 22 and 29. March 1998, my pay stub at age 22. First up is the one from when I joined the company…
What is the best order for someone coming from a different field to learn construction management as a supervisor? (Part 2)
Hello, everyone. This is Enta. What’s the best order for someone coming from another field to learn construction management as a supervisor? (Part 1) This is a continuation of the previous post. ⑤ The basic rule is to “always document” any discrepancies between the drawings and the site. This is extremely important. There are almost no construction projects where the drawings and the site match perfectly. Especially when it comes to slope work…
