Technical disclosure is an extremely important technical management work of construction enterprises, is the continuation and improvement of construction scheme, and is also the last pass of project quality pre control
.
The purpose is to make the technical personnel and workers involved in the construction familiar with and understand the characteristics, design intent, technical requirements, construction technology and problems that should be paid attention to
.
2
.
The role of technical disclosure enables every technical personnel participating in the construction activities to make clear the specific construction conditions, construction organization, specific technical requirements and targeted key technical measures of the project, and systematically master the overall picture of the construction process and the key parts of the construction
.
Through the technical disclosure, each worker participating in the construction operation of the project can understand the specific work content, operation method, construction technology, quality standard and safety precautions of the divisional and subdivisional works to be completed, so as to make the task of the construction operators clear and have a number in mind, so as to achieve the goal of orderly construction, so as to reduce various common quality problems and improve the construction quality
.
3 Classification of construction technology disclosure (1) construction organization design disclosure (1) key and large-scale project construction organization design disclosure: the technical director of the construction enterprise shall disclose the main design requirements, construction measures and important matters to the main project management personnel
.
Other engineering construction organization design disclosure shall be conducted by the project technical director
.
② Technical disclosure of special construction scheme: the professional technical director of the project is responsible for the disclosure to the professional foreman according to the special construction scheme
.
(2) The construction technical disclosure of sub project shall be conducted by the professional foreman to the professional construction team (or professional subcontracting)
.
“Four new” technical disclosure: the technical director of the project shall organize relevant professional personnel to prepare and disclose
.
(3) Technical disclosure of design change technical disclosure of design change: the technical department of the project shall disclose to the professional foreman according to the change requirements and in combination with the specific construction steps, measures and precautions
.
(4) The special disclosure of surveying engineering shall be made by the engineering and technical personnel to the surveyors
.
(5) Safety technical disclosure the technical personnel in charge of project management shall disclose the technical requirements for safe construction to the construction teams and operators
.
02 compilation requirements of construction technical disclosure 1
.
It must comply with the construction specifications, technical operation procedures, quality acceptance specifications, engineering quality evaluation standards and other corresponding provisions
.

.
It is necessary to implement various national technical standards, including units of measurement and names
.
3
.
Meet and realize the technical requirements in the design and construction drawings
.
4
.
It should conform to and reflect the intention and specific requirements of the technical disclosure of the superior technical leader, and should conform to and implement the requirements of the construction organization design or construction scheme, including the requirements of technical measures and construction progress
.
5
.
For different levels of construction personnel, the depth and detail of the technical disclosure are different, that is to say, the depth of the content and the way of explanation for different personnel It should be targeted
.
6
.
Technical disclosure should strive to achieve: the main items are complete, the contents are specific and clear, conform to the specifications, the key points are prominent, the expressions are accurate, the values are based, and the diagrams are supplemented when necessary
.
It can play a guiding role in engineering construction, with pertinence, guidance and operability
.
7
.
There should be no similar contents such as “refer to ×××× (specification) for matters not covered in the technical disclosure”
.
The construction technical disclosure shall be organized by the technical director of the project, and specifically prepared by the professional foreman and / or the professional technical director
.
After being approved by the technical director of the project, the professional foreman and / or the professional technical director shall make the disclosure to the construction team leader and all construction workers
.
8
.
The construction technical disclosure shall be conducted before the project construction
.
03 preparation content of technical disclosure 1 Preparation format of technical disclosure (1) project overview (2) work content and workload (3) quality, safety, progress, civilized construction, environmental protection and other objectives (4) construction preparation: ① material preparation; ② machine preparation; ③ working conditions and personnel preparation
