We are aware of the importance in providing the construction service in which the requirements of Army Corps Engineering Manual 385-1-1, Japanese Safety and Health Regulations, and local regulations are strictly complied. Thus, we prepare and implement the site specific plans, understanding requirements for health control and management, training practice, requirements for equipment, requirements for facility, and assigning of work qualified personnel for each work. In the management of safety and health at the construction site, we have emphasized following point of concerns;

• Preparation of safety and health management plan

• Initial site administrative training.

• Pre-construction meeting for safety and health.

• Implementation of safe construction cycle operations

• Installation of supervisor (competent person) meeting.

• Responsibilities of subcontractors (involvement to preparation of work procedure plan, installation and operation of council organization)

At the construction site of contract projects, multiple contractors of prime contractor, sub- contractors, and secondary sub-contractors are conducting each task mixed at the same location, it makes safety and health management more difficult and complicated;

therefore, we are committed to prevent the occupational accident be attributed by such conditions. The safe construction cycle operation (SCCO) is to be applied to daily work of site construction. As for the management in providing safety and health environment throughout the entire projects, 374CS/SCXR is also committed to implement the systematic construction management procedures. All the project staff including the sub-contractors has responsibility to meet at once before the construction starts, and discuss a work flow and schedule.

COMPLIANCE WITH FEDERAL OHSA AND EM 385-1-1.

A compliance with the requirements will be ensured by entire workforce of the company. 374 CS/SCXR has been conducting various projects for the 374CS in the past. We have been studying the requirements, developing the safety management system and training the employees on the accident prevention planning. As a result, we have successfully completed past performances without any severe occupational injury or fatality. Therefore, this company is dedicated to remove such an event by strictly complying with the OHSA and EM385-1-1. Requirements.
