Basic content (1) whether there is unlicensed design or leapfrog design; Whether the drawings are formally signed by the design unit( 2) Whether the geological exploration data are complete( 3) Whether the design drawings and instructions comply with local requirements( 4) Whether the design seismic intensity meets the local requirements( 5) Whether there are contradictions between the drawings jointly designed by several design units; Whether there are contradictions between professional drawings and horizontal, vertical and sectional drawings; Mark whether there is any omission( 6) Whether the general layout is consistent with the geometric dimension, plane position and elevation of the construction drawing( 7) Whether fire prevention and fire fighting meet the requirements( 8) Whether there are errors and contradictions between building structure and professional drawings; Whether the plane size and elevation of structural drawing and architectural drawing are consistent; Whether the representation methods of architectural drawings and structural drawings are clear; Whether the drawing standard is met; Whether the embedded parts are clearly indicated; Whether there is a reinforcement list or whether the structural requirements of reinforcement are clearly shown in the drawing( 9) Whether the construction unit has various standard atlas listed in the construction drawings( 10) Whether the material source is guaranteed and whether it can be replaced; Whether the conditions required in the drawing can be met; Whether there are problems in the application of new materials and technologies( 11) Whether the foundation treatment method is reasonable, whether there are nuclear technical problems that cannot be constructed and are not convenient for construction in buildings and structures, or problems that are easy to lead to the increase of quality, safety and engineering cost( 12) Whether there are contradictions between or between process pipelines, electrical lines, equipment devices, transportation roads and buildings, and whether the layout is reasonable( 13) Whether construction safety and environmental sanitation are guaranteed( 14) Whether the drawings meet the requirements of the supervision outline

.

The designer shall answer the questions raised by all parties

.

The minutes of the review meeting shall be prepared by the general design unit and the supervision department respectively, and the minutes of the review meeting shall be organized by the construction unit and the supervision department according to the requirements of the project specification

.

The purpose of design disclosure and drawing joint review is to enable all parties involved in the project construction to understand the leading idea, architectural concept and requirements, adopted design specifications, determined seismic fortification intensity, fire rating, foundation, structure, internal and external decoration and electromechanical equipment design, as well as the requirements for main building materials, components, fittings and equipment The requirements of new technologies, new processes, new materials and new equipment adopted and matters needing special attention in construction, master the technical requirements of key parts of the project and ensure the project quality

.

The meeting time shall be determined by the supervision department and notified

.

Time of design disclosure and drawing joint review shall be carried out before the commencement of the project

.

Construction shall not be delivered without confirmation

.

The design unit must make systematic design and technical disclosure to the submitted construction drawings in accordance with the relevant provisions of the national design technology management

.

3、 Organization of design disclosure and drawing joint review meeting 1

.

These phenomena are abnormal

.

Qualification of the design unit, whether there is unlicensed design or leapfrog design: whether the construction drawings have been signed by personnel at all levels of the design unit and reviewed by the construction drawing review organization.

.

Because the site and time of joint drawing review and design disclosure are roughly the same, many small partners always don’t know what to prepare for joint drawing review and design disclosure, who is ahead and who is behind, and some even confuse the two..

.

Now many projects have started, and the construction drawings are not complete, so that the later drawings can be used for construction

.

The joint review of drawings shall not be omitted, and the disclosure and joint review shall be carried out even if the new drawings are supplemented during the construction process

.

Construction drawings are the most direct basis for the construction unit and the supervision unit to carry out work

.

The minutes of joint review shall be prepared and signed by all parties

.

.

The design unit shall submit complete construction drawings: the drawings related to each discipline must be complete and complete: the drawings of important divisional and subdivisional disciplines urgently needed by the construction unit can also be disclosed and joint reviewed in advance, but the disclosure and joint review shall be unified after all sets of drawings arrive

5、 Key points of design disclosure and drawing joint review 1

.

Therefore, the design disclosure and drawing joint review are more necessary

.

Construction design disclosure (1) requirements for construction scope, quantities, workload and test methods( 2) Explain the construction drawings, construction scheme measures, operation process and quality and safety measures( 3) How to standardize and evaluate process quality( 4) Technical inspection, inspection and acceptance requirements( 5) Increasing production and saving indicators and measures( 6) Contents and requirements of technical records, etc

.

Today, let’s take a look at the differences between joint drawing review and design disclosure! Purpose of drawing joint review: find out technical problems, formulate solutions, find out the problems existing in drawings, reduce drawing errors and eliminate hidden dangers

.

Organizer: construction unit

.

Purpose of design disclosure: explain the design intent, explain the design documents and clarify the design requirements

.

Before the design disclosure and drawing joint review, the owner, the supervision department, the construction unit and other relevant units must designate relevant technicians in charge of the project to read the drawings for self review, preliminarily review the drawings of the discipline, and carry out necessary review and calculation

.

Participants shall include relevant personnel of supervision, construction, design, construction and other units

.

3

.

Firstly, the design unit shall introduce the design intention, structural design characteristics, process layout and process requirements, precautions in construction, etc

.

All professional drawings must be checked

.

2、 Principles to be followed in design disclosure and drawing joint review 1

.

Basic contents 1

.

Time: before the design disclosure, it is to submit it to the design unit one week before the design disclosure, so as to explain the problems raised during the joint review of drawings during the design disclosure

.

Engineering drawings for design disclosure and drawing joint review must be confirmed by the owner

.

For engineering projects and construction drawings directly involving the equipment manufacturer, the ordering unit shall invite the manufacturer’s representative to the meeting, and the owner, the supervision department and the representative of the design unit shall conduct technical disclosure and drawing joint review together

.

All units conduct research and coordination on Problems and formulate solutions

.

The minutes of the review meeting shall be prepared by the general design unit and the supervision Department respectively, including the minutes of the technical disclosure meeting organized by the construction unit and the supervision department, The chief supervision engineer shall sign the minutes of design technical disclosure meeting and submit them to the owner, designer and constructor for countersignature

.

Design disclosure and drawing joint review are important links to ensure the project quality, the premise to ensure the project quality, and the main steps to ensure the smooth construction of the project

.

Drawing design disclosure (1) natural conditions, engineering geological and hydrogeological conditions of the construction site( 2) Design leading ideas, construction requirements and ideas, and specifications for use( 3) How to determine the design seismic fortification intensity( 4) Explain basic design, main structure design, decoration design, equipment design (equipment selection), etc( 5) Requirements for foundation, structure and decoration construction( 6) Requirements for building materials, requirements for the use of new materials, new technologies and new processes, etc

.

Meeting minutes sorting unit: design unit

.

Time: after the joint review of drawings

.

The supervisor and all relevant units shall pay full attention to it

.

During design disclosure and drawing joint review, the design unit must send main designers responsible for the project to attend

.
