Appointment of technical administrator of waterworks
Consignor client side: Necessary, Consignee side: Unnecessary

Q. What types of order methods are available?

Contract determination methods Outline Merits Demerits
Open competitive bidding
  • Bidding in which people who satisfy certain participation requirements can participate in the competition freely.
  • The person who participates in competition and bids at the minimum price is determined as the successful bidder.
  • Fairness and transparency of bidding are high and monitoring by third party is easy.

  • Reliable contractors are selected.
  • Certain competitiveness is ensured.
  • Number of competition participants is limited, thus competitiveness becomes low compared to open competitive bidding.

(Open competitive bidding and selective bidding)
  • The person whose conditions including technical strength were the best among people who tendered a bid within the predetermined price range is determined as the successful bidder.

  • Selecting and securing people of experience or academic standing are required.
  • Selection capability of procuring service is required when evaluating technical power of participants.
  • Procedures for making a bid and concluding agreement are complicated, thus it may take time to complete the contract.

Monitoring system for solar power (stand-alone power source)

This system allows the Web monitoring and measurement by installing a package consisting of stand-alone power source - "solar power unit", measuring devices and wireless communication unit. This is for a difficult-to-Web-monitor place due to no power source available such as a water reservoir in remote mountainous area.

Stand-alone power supply system
Constructing the monitoring system of facility information (water level, flow rate, turbidity, temperature and opening, etc.) by using natural energy (sunlight)
Minimum remote monitoring device
Remote terminal unit data could be browsed through minimun IT gears such as PC, mobile phone and iPad, etc.
Equipped with multi-functions
Streaming of video images through the monitoring camera
