About
About Yamada's one-stop construction
In order to utilize the know・how of many years of in-house original construction work results and a wealth of human resources, not only for painting but also for repair work in general, we provide a wide range of services from planning and design to construction.We have made it possible to "one-stop construction" to collectively manage a series of processes until completion of construction.
Features
(01)
Cost reduction because it is a one-stop service
In steel bridge repair work, we can take on the series of processes from planning, design and estimation to construction planning, construction work (floor slab repair, telescopic contact repair and replacement, support repair and replacement, installation of falling bridge prevention devices, crack repair and preventive maintenance, base adjustment, painting, etc.), construction management, and completion, which reduces total costs.
(02)
Quick response because it is a one-stop
Since all decision・making and communication in each process can be completed by one company, time loss in confirmation and judgment can be reduced as much as possible.
And with the use of quick decks, safety and efficiency are further enhanced.

Steel bridge repair work by one-stop construction
Comprehensive support from planning and design to construction construction and completion.
In the field, it is possible to efficiently carry out various repairs to finish painting by utilizing the quick deck owned by the company.

Construction Management - Completion
01
Planning, design and accumulation
The shape of the bridge and the conditions on site vary. The plan and design will be carried out after carefully investigating the route to the site, where equipment is installed, and the existing coating conditions.
We will calculate the amount according to the design content. Based on the results of the coating film survey, safety costs will also be recorded in accordance with related laws and regulations.

Construction plan
To meet the requirements of the orderer and to make the construction safer, better, cheaper, faster and less environmental impact.Determine the method and procedure for construction.
To this end, we conduct on・site inspections to understand the surrounding environment, conduct on-site inspections to thoroughly investigate the conditions of the contract with the ordering party, and consult and coordinate with the local community.Based on the preliminary investigation, the construction plan is drawn up after technical examination of the construction method, the construction order, the machine used, etc.

Construction Management - Completion
The construction management will be carried out to ensure that the contents of the construction plan match the construction on-site and that the contents can be confirmed, and the construction will be completed.
In addition to daily production and quality control, we also manage the machines used and materials used.
Installation of scaffolding
Check the shape after the plate repair
Replacement of accounts
Confirmation of environmental compliance of the machine used
In order to handle hazardous substances, management and safety measures for workers are also essential.
We conduct regular in・house patrols (on-site and in writing) to correct any defects immediately.
