About Yamada's one-stop construction
In recent years, one-stop service has been attracting attention in various industries.It means "a business form that can receive various services at once."
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.

(01)
Cost reduction because it is a one-stop service
In the steel bridge repair work, from planning, design and accumulation, construction planning and construction work (floor plate repair, telescopic joint repair and replacement, bearing repair and replacement, bridge prevention equipmentOur company undertakes a series of processes from installation, crack repair and preventive maintenance, ground adjustment, painting, etc.), construction management, and completion.You can reduce the cost.

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.

Planning, design and accumulation
The shape of the bridge and site conditions vary.We plan and design after carefully investigating the delivery route to the site, the location of equipment installation, and the state of the existing coating film.
We will calculate according to the design content.Based on the results of the coating film survey, safety measures in accordance with relevant laws and regulations will also be recorded.

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
Construction management is carried out to ensure that the contents described in the construction plan are consistent with the on-site construction, and that the contents can be confirmed, aiming for completion.
In addition to daily form management and quality control, we also manage the machines 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.
