Project management during the rainy season is difficult

Hello, everyone. This is Enta. The rain is causing major delays on our site. How are things going on your sites? This tends to happen with any project that involves earthwork, doesn’t it? When it comes to earthwork on slopes, you often have to resort to single-cut excavation, but if you dig carelessly on a rainy day, it could lead to a collapse…

This Is the Type of Construction Work Site Supervisors Hate the Most!

Hello, everyone. This is Enta. I imagine everyone is busy as the fiscal year comes to a close. We’re busy too, but we have a little breathing room thanks to gaps between job sites and scheduling conflicts. However, we don’t have enough downtime to take on other projects… We have private-sector projects waiting for us as well, but it’s not a situation where we can just jump right in…

Site Supervisor’s Planning Techniques | Checkpoints for Anticipating the Future and Keeping the Site Running Smoothly

Hello, everyone. It’s Enta here. It’s crazy cold, isn’t it!!! It’s enough to scare you. In a world where it’s minus 7 degrees during the day, the drilling fluid freezes the moment it comes out. Lately, as I’ve been out on site, I’ve been gradually getting back into the swing of things. And the fatigue is starting to…

The schedule provided to the contractor should consist solely of actual calendar days.

Hello, everyone. This is Enta. When we’re talking about the construction process, there are often people who bring up things that haven’t even happened yet, lol. They’ll say something like, “It’ll take X days to install the lath and Y days for the spray application, so the whole thing will take Z days.” And then I’ll say, “Yeah, I know. That’s the plan.”…

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…

Lowering Workability Improves Productivity | A Paradox

Hello, everyone. This is Enta. Have you ever thought about the balance between workability and quality in quality control? Let’s take cement slurry, which is commonly used. In a flow test, it typically takes 10 to 18 seconds, with a maximum of 22 seconds (for railways), right? How long does it usually take you to apply it? Well, one…

About 1 hour of overtime is reasonable | Work Style

Hello, everyone. This is Enta. Are things getting pretty busy at your workplaces yet? Things are starting to pick up at mine, so I’m thinking of working an extra hour a day for a while. Working that extra hour a day is incredibly effective during this time of year. A quick calculation shows that in one hour…

Gradually Tightening the Production Schedule | A Slope Contractor’s Planning Process

Hello, everyone. This is Enta. The other day, I was drawing up our company’s schedule through the winter, and I kept thinking, “Oh man, this is bad… oh man, this is bad…” lol. We use Bravio, a tool that makes it easy to create Gantt charts online. It’s really convenient for managing schedules, so I highly recommend it. (My coworkers…

Key Factors for Staying on Schedule | Site Management

Hello, everyone. This is Enta. We just wrapped up another job site the other day. It was a project that started with a design change last year and went through quite a few twists and turns, but we somehow managed to align our schedule with the general contractor’s. Although there weren’t many holes to drill, coordinating everything was still quite challenging. If we had a whole week just for drilling, it would be easier to…
