How to do a good job in construction technical disclosure

Zheng Ming, Shanghai Engineering Office

Technical disclosure (also known as work instructions) is extremely important for construction companies

An important piece of technical management work, its purpose is to enable all managers and operators to understand the characteristics, design

intentions, technical requirements, and construction of the work they undertake. process and issues that should be paid attention to, and effectively implement all the contents in the disclosure during construction to achieve the purpose of improving construction quality. According to the difficulty, scale and other conditions of project construction

, technical disclosures within the scope of construction personnel at different levels are divided

For design disclosures, the chief engineer of the unit reports to the technical team of the project department. The technical explanation of the construction plan of the person in charge

, the technical explanation of the construction plan of the project department to the project functional department personnel

, and the technical explanation to the operation

Technical briefing conducted by the squad leader and workers.

In recent years, the management work of Lugong has developed rapidly, and the project method construction

has been widely adopted, but technical communication work is regarded as the basic management work

, not only has it not been canceled or weakened, but it has been strengthened, and the requirements are stricter and more specific. Its role in construction is irreplaceable. According to the author's investigation of various regions, units and project departments of the Secret Bureau. Regarding

this work has inconsistent understanding, good and bad, good and bad, especially

it is the technical briefing by the supervisor engineer to the work team leader and workers,

In terms of form, the content of the disclosure is not targeted, and is even plagiarized repeatedly.

In response to this problem, combined with my actual work in the past few years, I will talk about how to do a good job in explaining construction technology: .

1 Technical briefing is clear and precise

Construction projects are characterized by construction complexity, continuity and variability,

as well as product unity, which requires The project management work of our Lugong Enterprise

is complex, continuous and changeable, which requires strengthening the management of technical communication during construction. For everyone involved in project construction and management, through technical briefing,

understand the specific work of the sub-projects they want to complete

Contents, operating methods, construction techniques, quality standards and safety precautions

etc., so that operators have clear tasks, are well aware of them, and cooperate with each other and work procedures

The handover is in an orderly manner to achieve orderly construction

to reduce various common quality problems and improve construction quality.

4 Issues that should be paid attention to in technical disclosure of construction projects

(1) Technical disclosure should strictly implement construction and acceptance specifications

Regulations, construction and acceptance The requirements in specifications and procedures, especially

quality standards, may not be modified or deleted arbitrarily. Technical disclosures should also meet

the relevant requirements for construction organization design, and should understand and understand the technical requirements put forward in technical documents such as technical disclosures at the higher level

and should not be ignored

Intentional violation of relevant provisions in the document. Disclosure of meetings held by the company

Detailed minutes should be kept, including the names of the participants,

the date, the content of the meeting and the technical decisions made at the meeting. Meeting minutes

should be complete and should not be lost or torn arbitrarily. They should be archived and stored as technical meeting documents

for a long time. All written technical disclosures should be reviewed

and a manuscript should be left with neat and clear handwriting and correct data citations.

The issuer, reviewer, and recipient of the face-to-face disclosure should all sign and seal.

) A construction project is composed of multiple sub-projects

each of which is equally important to the entire building

Importantly, the technical briefing for each sub-project should

be comprehensive, careful and thorough. For sub-projects that are large in area, large in quantity, and have high economic benefits, a more detailed technical explanation must be conducted; compared to projects that are sporadic, special locations, hidden projects, or have low economic benefits. The sub-projects of

should also carry out technical explanations equally seriously. Conduct detailed technical explanations for important

structures and parts with heavy loads, but also

minor structural parts, such as prefabricated beams, etc., should not be ignored, and these

>

The parts are prone to quality accidents and safety accidents. Some project departments only pay attention to the main structure during technical briefing and do not pay enough attention to waterproofing and decoration projects. Their performance is obvious during technical briefing. Therefore, these projects

>

The main structure is relatively good, but the waterproofing and decoration quality of the building are relatively poor. This is especially obvious when constructing civil buildings, which makes the enterprise very

passive. No greater advantage can be formed in the market.

(3) During the technical briefing, special attention should be paid to the company's current

common construction quality problems and work-related injuries, so as to nip them in the bud and

Project quality accidents and casualty accidents are nipped in the bud.

Possible quality accidents and casualties should be prevented during technical disclosure

Accidents should be made to make technical disclosure comprehensive, thoughtful and complete. And

the technical explanation should be carried out as early as possible, so that grassroots technical personnel and workers have sufficient

time to digest and understand the relevant technical issues in the technical explanation, and be prepared as early as possible

, so that construction personnel can be well aware of the construction tasks in order to complete the construction tasks

(4) Supervision and inspection of technical explanation work. Technology at all levels

Managers should not assume that everything will be fine if they have already conducted oral or written technical communication

Generally speaking, this is just a communication work

At the beginning of the disclosure, a lot of work is to supervise and inspect the effectiveness of the disclosure. During the construction process, grassroots technicians should be reminded repeatedly

Specific construction operation parts have been strengthened or prompted to meet the relevant requirements in technical briefings, the "three inspection system" has been strengthened, inspections during the construction process have been strengthened, and intermediate acceptance of the project has been strictly enforced. It has been found that Problems

Solve them promptly to avoid quality accidents or rework waste.

(5) The implementation of technical disclosure can take a variety of forms

so that every worker is familiar with and understands the specific

details and Require. For example, before the construction of a sub-project, the relevant content in the technical briefing can be hung on the wall in the form of a blackboard report.

Before and after work, arrange work and assign tasks again.

一53 一

For new technologies, new processes, and new structures, ask experienced workers from outside units or the company to perform technical demonstrations, or provide sample demonstrations. Understand the operating steps and be aware of them

to avoid various quality or safety accidents

(6) Technical briefing is an important part of construction management and is

An essential step in the construction technology management process. It is extremely wrong to believe that

technical briefings are old-fashioned and old-fashioned. They only read out the text and become formal

. After the briefings are given, they are not carefully supervised and inspected. Some

people think that this is not a new process or new structure, and that the construction workers are all old

workers, so they simplify the disclosure content, or even do not disclose the details and do not check

Some people think that there is nothing to explain about painting, door and window projects, etc., which will not affect structural safety, and they adopt a careless attitude towards technical explanations.

For some relatively sporadic types of work, such as embedded parts, ironwork, etc., no disclosure, no questioning, no inspection.

The above are common and extremely wrong. They are the main reasons for quality accidents.

Seriously doing a good job in engineering construction technology is to ensure that the work is completed

The prerequisite for project quality and on-schedule completion of project tasks. It is a job responsibility that every construction technician must perform.
