Technical disclosure is a very important technical management work of construction enterprises, is the continuation and improvement of the 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
.

.
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 grasp the overall picture of the construction process and the key position 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 sub divisional works to be completed, so as to make the task of the construction operators clear and have a clear idea, and achieve the purpose 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

.
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
.

There should be no reference for “matters not covered” in technical disclosure ×××××（ And so on
.
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
.

.
The construction technical disclosure shall be conducted before the project construction
.
