Demolition Process

We are committed to delivering professional work in everything we do.

STEP.1
Site Inspection

We prioritize the safety of our customers and neighboring residents, carrying out every task carefully and reliably. Although we take every precaution to prevent accidents, we maintain third-party liability insurance to cover potential incidents during construction. Estimates are free, so please feel free to contact us.

After discussing your specific requirements, we inspect the property, identify items to be removed other than the building itself, and check road conditions to calculate an accurate demolition cost. If underground objects or unexpected work are discovered, we discuss the necessary measures with you and proceed only after obtaining your understanding and approval.

We check the following items:
・Construction area and type of protective sheeting
・Building structure and condition
・Surrounding environment and access routes for equipment and vehicles
・Scope of work
・Property boundaries with neighboring properties
・Underground objects
・Your preferences for the finished ground surface

STEP.2
Quotation
Based on the site inspection, we prepare and submit a quotation. Once you have reviewed and approved the details, we proceed to enter into a formal contract.
STEP.3
Notification to Neighbors

Demolition work may cause noise and vibration that affect nearby residents. We visit neighboring properties to explain the work, offer our greetings, and provide a small courtesy gift.

We can also arrange a traditional Shinto ground-breaking or purification ceremony upon request.

STEP.4
Utility Disconnection and Service Removal
We arrange for the disconnection and removal of gas, electricity, telephone services, utility meters, service pipes and wiring, internet connections, and cable services. Specialized contractors carry out the necessary removal work.
STEP.5
Scaffolding and Protective Sheeting Installation
Because demolition work involves working at heights, we first install scaffolding and protective barriers.

We then cover the scaffolding with protective and soundproof sheets to reduce dust, debris, and noise, minimizing the impact on neighboring residents.

STEP.6
Removal of Fixtures and Other Structures
Before demolishing the main structure, we manually remove items that can be taken out separately.

These include tatami mats, window frames and sashes, insulation materials, doors and fittings, roof tiles, interior fixtures, residential equipment, gypsum boards, and decorative interior wall panels.

STEP.7
Demolition of the Main Building
Using heavy machinery, we demolish the remaining building structure, including walls, roofs, beams, and columns. We then excavate and remove the foundations.

We take great care to avoid damaging nearby structures that are not included in the demolition work, such as neighboring block walls.

STEP.8
Waste Sorting and Collection
Materials generated during demolition, including wood, metal, plastic, and concrete rubble, are carefully sorted and handled in accordance with the construction waste manifest system.
STEP.9
Underground Inspection
After the building has been demolished, we use heavy machinery to excavate and inspect the ground, checking for any remaining demolition waste or concrete beneath the surface.
STEP.10
Ground Leveling and Site Preparation

Once the foundations have been demolished and removed, we carefully level the ground, leaving the site cleared and ready for its next use.

About post-demolition site preparation:

If you plan to use the site as a parking lot, we can spread crushed stone or pave the surface with concrete or asphalt.

Upon request, we can also provide a construction waste manifest, which documents waste disposal and helps clarify how and by which company the waste was transported and processed.
