Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

I'm in Tokyo again today because the KTB Anchor Association held its general meeting the other day.<\/p>\n

Tokyo really is amazing, isn't it?<\/p>\n

Everywhere you look, there's construction going on, with buildings being built right in the gaps between other buildings...<\/p>\n

There's still a long way to goTokyo Is Expanding<\/span><\/strong>That's right.<\/p>\n

While regional cities are shrinking, Tokyo is expanding.<\/strong><\/span><\/p>\n

 <\/p>\n

\"\"<\/p>\n

I can really see why construction companies in Tokyo are so busy.<\/p>\n

The major general contractors, in particular, are really impressive.<\/p>\n

At the general meeting the other day, a representative from Nexco mentioned that,<\/p>\n

More than 50 percent of expressways have been in service for over 30 years<\/span><\/strong><\/span>That's what they say.<\/p>\n

What this means is that from now on,Signs of significant deterioration are becoming apparent on the expressways<\/strong>That's what it means.<\/p>\n

This means there is a high probability that large-scale renovation projects and the like will be commissioned.<\/p>\n

The renovation project is on a scale of 480 billion yen!<\/p>\n

Hey, honey! That's 480 billion yen!<\/strong><\/span><\/p>\n

So, the main construction work will likely involve replacing the floor slabs and so on.<\/p>\n

Our job as slope engineers is probably...<\/p>\n

It might be a long shot, but it's possible! I'm sure... I'm sure...<\/p>\n

The scope of the renovation is<\/h3>\n

In practice, structures that have exceeded their service life\u2014such as those built 50 years ago\u2014as well as those with sprayed concrete or mortar finishes will likely be subject to these regulations.<\/p>\n

And the Landscaping Department is included as well, isn't it?<\/p>\n

When it comes to landscaping in the past, we used to use species that are now banned without a second thought.<\/p>\n

There will likely be some renovations in this area.<\/p>\n

In addition, areas where landscaping results in high maintenance costs will likely be replaced with concrete.<\/p>\n

Naturally, work on rock bolts and anchors will also be part of the renovation.<\/p>\n

In the past, rock bolts were made of uncoated raw material.<\/p>\n

Also, I think there are quite a few defective self-tapping bolts.<\/p>\n

With anchor work, it\u2019s unclear whether the anchors will be replaced or reinforced.<\/p>\n

I suppose they'll conduct an investigation and make the necessary repairs.<\/p>\n

Life Cycle Cost<\/h3>\n

In future construction method selection, there will be an increasing trend toward adopting products with favorable life-cycle costs.<\/p>\n

What Is Life Cycle Cost?<\/a><\/span><\/span><\/strong><\/span><\/p>\n

So, it seems we\u2019re no longer in an era where only the cheapest items sell.<\/p>\n

I suppose the companies that develop those kinds of products are the ones that will survive.<\/p>\n

The cost of goods is rising, but the cost of labor is\u2193\u2193\u2193<\/strong>As for the current situation, lol<\/p>\n

Especially in the countryside, lol<\/p>\n

If there's no work, companies will compete fiercely, and rates will just keep going down.<\/p>\n

For us subcontractors and small and vulnerable independent contractors, social insurance alone is a matter of life and death, yet,<\/p>\n

Unit prices have dropped\u2014it's a real headache!<\/p>\n

So, I suppose that\u2019s why people are leaving the industry at an accelerating rate...<\/p>\n

Let's make the civil engineering industry even more vibrant.<\/span><\/strong><\/span><\/p>\n

Government agencies, place even more orders!<\/span><\/strong><\/span><\/p>\n

 <\/p>\n

See you later.<\/p>","protected":false},"excerpt":{"rendered":"

With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here. I look forward to your continued support.","sameAs":["http:\/\/enta-d.co.jp\/","https:\/\/www.facebook.com\/norimenman\/","https:\/\/www.instagram.com\/enta.d\/","https:\/\/x.com\/norimenman","https:\/\/www.youtube.com\/c\/entadnorimenman"]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/norimen.net\/large-renovation-construction-era\/#local-main-organization-logo","url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","contentUrl":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","width":220,"height":50,"caption":"\u65b0\u30a8\u30f3\u30bf\u306e\u6cd5\u9762\u7ba1\u7406\u587e"}]}},"jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"publishpress_future_action":{"enabled":false,"date":"2026-10-14 17:26:25","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"jetpack_featured_media_url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2017\/06\/86d7618bf8cde7b11a05457070cab4aa.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/3611","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/comments?post=3611"}],"version-history":[{"count":1,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/3611\/revisions"}],"predecessor-version":[{"id":60658,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/3611\/revisions\/60658"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/3615"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=3611"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=3611"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=3611"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
