QAQC Management for Construction Projects
Thread Content
Let’s start with a simple question: Do QC engineers working on construction projects usually have any certifications? Or is a regular construction engineer sufficient? I previously helped a North American client review the mechanical completion documents prepared by a well-known local subcontractor, and the work was done very well. But it’s completely unknown where this information comes from, which position is responsible for producing it, and how detailed it should be; therefore, I would like to ask Haiyou for advice. First, let’s talk about the general approach to the mechanical completion documentation here: The construction contractor should have a QA plan, which should outline the inspection plans for various specialties and materials, including who will be involved in these inspections ； The construction contractor submits a QC inspection form related to the aforementioned QA plan for the owner’s approval. These forms are generally categorized by specialty, including those for material submission, construction submission, and submission after installation; thereafter, a comprehensive summary table is prepared ； In accordance with the requirements for commissioning, the owner assigns the PID, control circuit diagrams, SLDs, etc., along with the associated structures and facilities, to various commissioning subsystems, and provides lists of all types of pipelines, equipment, machinery, instruments, and electrical components for each subsystem ； The construction subcontractor, based on the content list of each commissioning package and by category, checks the corresponding items on a master summary table, thereby determining the types of checklists that should be included in the mechanical completion document package for that commissioning package. Once approved and signed by the owner, it can be used as the catalog for this commissioning package ； Next, for each system, content is added to it according to the approved catalog. Procedurally, I think it’s similar in China as well. What I would like to ask now is: 1. I took a close look, and for each instrument cable, there are three forms – one is the material inspection form, one is the installation process record form, and one is the installation quality inspection form. Question: When are tables like these three generated? 2. Material inspection form: It is generally checked when the materials are taken from the owner’s main warehouse. When picking them up, there are still large quantities of materials available; how do you determine which one is meant for that instrument cable at that time? 3. Are the material submission plans and forms usually issued by the warehouse or by the construction department? For a manager new to quality management, what are some things to keep in mind or be reminded of?
It seems you need to gain more experience in QC. The simplest and correct way is to ask your construction manager or project manager. 1. The material inspection form should be submitted to the owner or supervision department before the materials enter the site, are prefabricated, and installed. The installation process record form is a self-inspection record for construction steps; if there are any concealed works, the supervisor’s signature may be required to approve it. A quality inspection form is required upon the completion of a sub-project or specific task; it must be signed by the construction party, the supervisor, and the owner. 2. The material submission form is already available with the owner; you only need to copy the certificate or license. 3. The material submission forms and plans are definitely prepared by the construction unit. Ultimately, it is the construction contractor that provides all the documentation required for registration.
Do QC engineers need a certificate, or can ordinary engineering professionals in construction or commissioning work suffice? In terms of roles, QA is responsible for formulating QAQC plans, while QC is in charge of daily inspections and preparing the handover documents, right?
What is the difference between QA and QC? Who can tell everyone?
These past two days, I have been asking questions while also doing my own research. QC, Quality Control, involves performing product inspections, including IQC, Incoming Quality Control, quality control of incoming materials ； IPQC--In-Process Quality Control Process quality control ； FQC--Final Quality Control refers to quality control of finished products, as opposed to OQC, Outgoing Quality Control, which is related to quality control at the time of product shipment. QC focuses on specific products rather than the quality system, which is the biggest difference from QA ； QA, Quality Assurance – it refers to the process of ensuring that product quality is satisfactory by establishing a quality assurance system. QA engineers need to not only know where the problems lie but also understand the solutions to those problems and how to prevent them in the future, whereas QC engineers only need to be aware that there are problems with the product in order to take action to control them. QC is equivalent to the police, while QA corresponds to the legislature and judges. The QC only needs to arrest those who break the law; it cannot prevent others from committing crimes or convict them through the system. If there are many criminals in a certain area, more police officers should be deployed there ； The Legislative Yuan is responsible for legislating to define what constitutes a crime, analyzing the causes and motives behind crimes, and identifying legal gaps to address them. That’s about it; I’m also researching and learning*.
That’s a great explanation; it’s more or less like that. QA represents a macroscopic system, while QC refers to the individual steps within it. QC does not require a strong theoretical foundation – only relevant professional knowledge is needed, whereas QA demands a solid theoretical basis; the concept of a system is what’s key here

It seems the poster works at a construction company, where things are very busy; nevertheless, it is still recommended that you take some time to review the sh3503 standards and tables. Read each form used in the construction of equipment, pipelines, electrical systems, and instrumentation several times, and consider in light of the actual situation why these forms need to be filled out, and why it is necessary for multiple parties to confirm these key points. What problems will arise if it’s not confirmed together? For example, in the case of pump installation, there should be an unpacking inspection record with signatures from several parties. Without such a document, if the owner purchases a pump and the construction party delivers it to the site only to find that it is defective, disputes will arise. If you go through each table in 3503 and understand half of them, your skill level will be sufficient to serve as a quality manager. As for what tasks within the project department should be handled by which department, as asked by the original poster, there are no fixed rules for this. It depends on the arrangements made by your project leader; there’s no need to worry about it.
Are there any similar tables or specialized solutions?
