As the title suggests: The design institute is responsible for the quality of the designs. May I ask, 1. In what aspects is the quality of designs reflected? 2. How can owners ensure design quality to prevent or reduce rework during construction?
Control what? How to control it? You can’t guide the design institute step by step, right?

A brief analysis: During the construction phase of our facility, the design firm we worked with was a leader in the industry (it’s not appropriate to reveal its name directly). The designers at that firm followed the design specifications strictly; there was no room for negotiation regarding those specifications. I didn’t understand this before, but after arguing the matter through, I now fully comprehend it. But if it falls outside the regulations, this design institute still needs to carefully consider opinions from all parties. This ensures quality in terms of cooperation and design. Of course, there are cases of rework. What kind of situations? There is little horizontal communication among different specialties within the design institute; as a result, issues such as pipes and supports interfering with each other, pipes blocking the positions of cameras, and ladders hindering movement up and down platforms occur. The key points of the three inspections and four determinations are to eliminate construction quality issues and optimize design implementation. Through the three inspections and four determinations, we made many design changes; we worked on-site in the design process, with excellent coordination among everyone involved.

Feasibility study phase: The selection of technical solutions must be scientific and reasonable – using mature technologies that are cost-effective and environmentally friendly. Preliminary design phase: Detailed plans for all aspects of the process, along with reviews and adjustments regarding the integration of different professional elements (it is advisable to conduct HAZOP analyses). Construction design phase: Detailed review of drawings is necessary. Equipment manufacturing phase: Technical specifications must be established, structural designs finalized, materials selected, and manufacturing processes supervised. Both parties involved should respect each other and maintain active communication
If the design institute is of high quality, the results will be good; if it’s poor, nothing matters – everything is decided arbitrarily and carelessly.
