What is a building for contaminated soil handling work that does not require a building application with a temporary roof? │ Overview and Case Studies

Temporary roofs are one of the most economical and efficient solutions for contaminated soil response work. Unlike temporary buildings, no building application is required, so they can be easily installed.

This article provides an overview of temporary roofs, their variations, and examples of installations. Please take a look.

Response construction site requiring contaminated soil and tents

Contaminated soil is soil (soil) with content exceeding the standard values for specified hazardous substances. Some are contaminated as a result of improper handling of hazardous substances from factories, while others are naturally occurring and contaminated.

Direct ingestion of contaminated soil or drinking groundwater, etc. in which contaminated soil has eluted can be hazardous to health. Therefore, the Soil Contamination Countermeasures Law has been formulated to assess the status of soil contamination and to prevent human health hazards caused by soil contamination.
This law defines the land that is subject to the obligation of soil contamination investigation, the specific hazardous substances to be covered, and the standard values.

In addition, soil may accumulate dioxins, which are produced by incomplete combustion of chlorine-containing substances, etc. The “Dioxin Special Measures Law” also establishes standards and regulations for dioxins, and sets out measures to be taken regarding contaminated soil.

At civil engineering-related construction sites that deal with contaminated soil, anti-scattering tents may be required depending on how the contaminated soil is treated and other factors.
In the case of VOC (Volatile Organic Compounds) contaminated soil, when the excavation and removal method is used and a tent is required for rain protection and dust control, or in the case of dioxin, PCB, mercury, and POPs, a tent with a front room tent and negative pressure control is required in principle.

What is a temporary roof?

Temporary roofs are an efficient solution to erect facilities needed only during the construction period without the need for a building application.

Building is a general term for structures with roofs, columns, and foundations. Temporary buildings to be installed for a limited period of time within one year require, in principle, an application for temporary construction.
On the other hand, temporary roofs installed within a construction site and used only during the construction period, which function as a roof (sunshade, shelter from rain, etc.), do not, in principle, require an application as a building.

Temporary Roof] Example of a building for construction work to deal with contaminated soil

Here are some examples of temporary roof installations. *These are all examples of temporary roof installations, although they are different from the case of contaminated soil response work.

Case Study 1

Fixed temporary roof (Seasonal product storage, Tokyo)
Temporary tents are useful for seasonal temporary increases in goods.
Large storage spaces can be easily secured and functional warehouses can be built in a short period of time.

Case Study 2

Fixed temporary roof (Osaka, 7.5m eave height type)
At the center, the space can be more than 8 meters.
This makes it possible to work with heavy equipment inside. The simple structure makes construction and dismantling easy.

Case Study 3

Telescopic temporary roof (for excavation of buried cultural properties, Tokyo)
The land is known to contain buried cultural properties, and about 9,000 excavations are conducted each year.
We work outdoors on sunny days and inside tents on cloudy days. Because work can be done all year round, surveys can be conducted in a short period of time.

summary

The temporary roof, which does not require a building application, can be easily installed as an anti-contaminated soil building. Taiyo Kogyo Corporation, which handles a large number of temporary roofing projects, has the ability to respond to a variety of issues and needs.
