TEPCO has technologies for construction management, such as quality, environment, schedule, and budget. TEPCO has been preformed a number of power cable tunnel projects with high quality structures, harmonized with environment, at a reasonable cost, under reliable supervision and management. Engineers of TEPCO have many experiences in power cable projects; therefore they don't only have abilities of construction management, but also these of construction planning, process control, and cost estimation.

Contents of quality control and schedule control are as follows.

• Quality Control
  To specify the quality standard of materials and satisfy these requirements, quality control on materials and structures are executed for the sake of securing specified quality and function. If there is a possibility that quality falls, the standard and construction method are revised and countermeasures are drafted.

All activities are executed in accordance with TEPCO's safety standard based on ISO 9000.

• Schedule Control
  In schedule control of TEPCO's projects, we constantly check the schedule and actual progress. If there is a possibility of delay or troubles, the causes are removed in advance. If unexpected delay or troubles occur, effective countermeasures are drafted. Therefore, power cable projects of TEPCO have been progressing smoothly for long time.

For the sake of removing any causes of delay or troubles, we negotiate with the relevant authorities to minimize the environmental impact particularly in urban areas, and we have been researching to improve the design and the construction methods.
