1.3.1 The work is to be put to bid in the form of general contraction of equipment supply, installation and It therefore has stringent requirement for the bidder. The constructor is responsible for providing equipment as well as the supply, installation and trial operation of the individual equipment. The constructor is responsible for providing equipment as well as the supply, installation and trial operation of the individual equipment according to the design requirement. The constructor is responsible for providing equipment as well as the supply as the installation and trial operation of the individual equipment according to the design requirement. If the constructor fails to reach the promised level of performance, he shall make necessary improvement of the equipment or replace it either in the testing period or the 20-month supervised operation.
1.3.2 Stringent requirements for installation
The requirements are as follows p>
The requirement is fairly stringent for the technical level of installation. A great number of domestically or internationally advanced equipment and instrumentation will be used and the equipment and instrumentation will be used in the installation. A great number of domestically or internationally advanced equipment and instrumentation will be used and the control of installation accuracy is of vital importance to the commissioning operation. management of the whole treatment plant will be computerized after installation and commissioning.
1.3.3 High degree of automation
The work utilizes the PLC integration and disintegration combination control to measure and control the level/interface, temperature, pressure, dissolved oxygen, concentration of sludge, and the level/interface of the water. The work utilizes the PLC integration and disintegration combination control to measure and control the level/interface, temperature, pressure, dissolved oxygen, concentration of sludge, alkalinity and acidity, flow rate, opening of control valves, concentration of poisonous gasses, voltage, current, power, etc. All process parameters will be displayed on CRT projector screens.
1.3.4 Many cross-operations
Construction of Construction of provided holes for underground pipeline networks, valve shafts and operating equipment must be done in conjunction with the public utility works. Therefore a large amount of cross-operations will be involved.
1.3.5 Many open-air operations
Since open-air operation will be greatly affected by weather. Operation should be carried out as quickly as possible if the weather condition permits and technical measures should be taken during performing construction in rainy weather. operation should be carried out as quickly as possible if the weather conditions permits and technical measures should be taken during performing construction in rainy weather.
