Regarding the power plant bidding plan
Thread Content
Our project is a waste incineration project. The plan is to start the bidding process for the incinerator at the end of September, with the winning bidder being responsible for providing the basic design for the incinerator, the waste heat boiler, and flue gas purification. Could someone with experience advise on how to arrange the subsequent bidding steps – which items should be bid on first and which later? Thank you
I’m not familiar with waste incineration projects, but the design institute should have an overall project schedule. You can take a look at how the design institute has arranged the sequence of installation and construction for these devices, and then formulate a bidding plan based on factors such as the manufacturing time required for these devices, transportation conditions, and whether assembly will be carried out in the factory or on-site, so that everything is coordinated properly in terms of timing.
Thank you. My supervisor gave me a equipment tendering schedule and asked me to fill in the dates. He told me that the tender for the incinerator will take place at the end of September, and that by December the incinerator manufacturer will provide the preliminary design (including the incinerator, waste heat boiler, and smoke purification systems). The final design will be completed 15 days after that, at Iron Foot Design Institute. Then he asked me to prepare a tendering schedule for the thermal control equipment, which includes the Distributed Control and Display System (DCS), electronic truck scales, systems for online continuous smoke monitoring, electric actuators and related equipment, large-screen display systems plus electronic digital instrument panels, an industrial television monitoring system for the entire plant plus monitoring equipment for the factory area, thermal measurement components, valves, automatic fire alarm and fire suppression systems, equipment for detecting toxic and flammable gases, public display screens, management and communication network systems, and complete sets of fire sprinkler systems. Which of these tasks should be carried out first and which later? . . Does DCS require waiting until the technical specifications are available after all those key equipment have been subject to bidding before design bidding can begin?
Equipment with a long production cycle should be subject to bidding first, followed by other auxiliary equipment; for valves and instruments, bidding can be carried out during installation (imported items need to be arranged earlier)
Could you be more detailed? Once the design institute has completed the basic design for the boiler, turbines, and flue gas purification, can we then proceed with hiring a DCS provider? . . The auxiliary machinery you mentioned. . . Um, please explain it in more detail. I really don’t understand. .
The contents of this table include four specialties: centralized control, communications, instrumentation, and fire protection. Fire protection, instrumentation, and centralized control can be carried out simultaneously; communications work can also be done. Some design interfaces can be maintained with the DCS to facilitate mutual support.
The procurement cycle for instruments is generally long, ranging from 3 to 6 months. The hardware, software, and programming cycle for DCS control systems are also relatively long. When we issue tenders, gas alarms and automatic fire alarms are included as part of the package. DCS, command phones, monitoring, and the video wall are also considered as a whole. The truck scale is needed in the early stage; since all process equipment must be weighed upon arrival at the factory, this item also needs to be bid on as soon as possible.
In fact, many things also depend on the drawings produced by the design institute. Nothing came out of it; how can you hold a bidding process?
Do you mean that for the DCS bidding process, it is necessary to wait until all the major systems have been bid on and the winners have been determined, after which the design institute will provide the technical specifications before bidding can proceed? Or can a tender be issued after the major manufacturers provide the basic design?
