Contents and process of design and drawing review
I, design and drawing review should follow the principle of design
1, the design unit should be submitted to a complete set of construction drawings: the professional interrelated drawings must be provided complete, complete: the construction of the important sub-parts of the unit of the construction unit in need of professional drawings in advance of the submission and review, but all sets of drawings to be unified and then review. And then unified submission and review. Now many projects have started, and construction drawings are not complete, so that after the arrival of the drawings to bring the construction. These phenomena are abnormal. Drawings can not be omitted, even if the construction process of a new map should also be made up and review.
2, in the design and drawings before the review, construction units, supervision and construction units and other relevant units must be designated in charge of the project in advance of the relevant technical staff to see the self-examination of the preliminary review of the drawings of the specialty, the necessary audits and calculations. Between the professional drawings must be checked.
3, design and drawing review, the design unit must be responsible for the project's main designers to attend. Design and drawings for the review of engineering drawings, must be confirmed by the construction unit. Without confirmation shall not be delivered to the construction.
4, where directly related to the equipment manufacturer's project and construction drawings, the ordering unit should be invited by the manufacturer's representative to the meeting, wells please construction units, supervision and design units and representatives of the Department of the technical review of the drawings together.
Second, the purpose of the design and drawing review
In order to enable the parties involved in the construction of the project to understand the leading ideas of engineering design, architectural concepts and requirements, the use of design specifications, to determine the seismic intensity, fire rating, foundation, structure, internal and external renovation and mechanical and electrical equipment design, the main building materials, components and equipment requirements, the use of new technologies, new techniques, new materials, new equipment requirements, the main building materials, components and equipment requirements. New materials, new equipment requirements and construction should pay special attention to matters, master the technical requirements of the key parts of the project to ensure the quality of the project, the design unit must be based on the relevant provisions of the national design and technical management of the construction drawings submitted to the design of the systematic technical briefings. At the same time, but also in order to reduce the drawings of the errors, omissions, contradictions, the drawings of the quality of the hidden dangers and problems in the construction before the elimination of the construction, so that the design and construction of drawings more in line with the specific requirements of the construction site, to avoid the waste of rework: in the construction drawings at the same time of the design of the technical submission of the Department of Supervision, the design unit, the construction units, construction units, and other relevant units need to be on the basis of the self-examination of the design of drawings on the basis of the meeting. Construction drawings are the construction unit and supervision unit to carry out the work of the most direct basis. At this stage, most of the construction supervision, design supervision is very little, the drawings in the error inevitably exists, so the design and drawing review is more necessary. Design and drawing review is to ensure the quality of the project is an important link, but also to ensure the quality of the project is the premise, but also to ensure the smooth construction of the project is the main step. Supervision and all relevant units should pay full attention.
Three, the design and drawings of the organization and procedures of the meeting
1, time design and drawings of the meeting in the project before the commencement of the meeting time by the Supervisory Department to decide and send a notice. Participants should include supervision, construction, design, construction and other relevant units.
2, meeting organization according to the "construction supervision specification" article 5.2.2 requirements, project supervision personnel should participate in the construction unit organized by the design of the technical submission will, in general, the design of the submission and drawing review meeting chaired by the superintendent of engineers, the supervision department and the construction unit, including subcontracting units, respectively, the preparation of records of the meeting, summarized by the Department of Supervision and the drafting of minutes, the director of supervision. Engineer should sign the minutes of the design and technical submission, and submitted to the construction, design and construction unit countersigning.
Four, the design and drawing review procedures
1, first of all, the design unit introduces the design intent, structural design features, process layout and process requirements, construction precautions, etc..
2, the relevant units of the problems in the drawings to ask questions.
3, the design unit of the questions raised by the parties to answer questions.
4, each unit for the problem of research and coordination, develop solutions. Write a summary of the meeting, and signed by all parties.
Fifth, the focus of the design and drawing review
1, the qualification of the design unit, whether or not unlicensed design or cross-level design: construction drawings signed by all levels of the design unit, whether or not through the construction drawings review organization review.
2, design drawings and instructions are complete, clear, coordinates, elevation, size, pipelines, roads and other cross-connections in line: drawing content, depth of expression to meet the needs of construction: construction of a variety of standardized atlases listed in the availability.
3, construction drawings and equipment, special materials, whether the technical requirements are consistent: the source of the main materials are guaranteed, can be replaced; new technology, the application of new materials is implemented.
4, whether the equipment specification is detailed, and specifications, regulations are consistent.
5, whether the civil structure layout and design is reasonable, whether it is closely integrated with the engineering geological conditions, whether it meets the seismic design requirements.
6, several design units designed drawings are not contradictory to each other: between the various specialties, between the plane and section, between the general and sub-diagrams are not contradictory: architectural drawings and structural drawings of the plan dimensions and elevations are consistent, whether the representation is clear: embedded parts, such as the setup of the holes reserved correctly: reinforcing steel schedule and reinforcing steel structure diagram is clear: concrete columns, beams, joints of the steel reinforcement Layout is clear, whether there is a node diagram: steel component installation of connection node diagram is complete: various types of pipe trench, support hangers (piers, etc., whether the coordination and unity between the professions: whether there is a comprehensive pipeline diagram, ventilation pipes, fire pipes, cable bridges are not touching.
7, whether the design meets the production requirements and maintenance needs.
8, construction safety, environmental health is guaranteed.
9, the building and structure whether there are technical problems that can not be constructed or inconvenient construction, or lead to quality, safety and project cost increase.
10, fire prevention, fire design to meet the requirements of the relevant regulations.
6, the design of the minutes and implementation
1, the project supervision department should be the construction drawings will be organized to summarize the records and is responsible for the formation of the minutes of the meeting. Signed by all parties involved, the minutes are regarded as part of the design documents (construction process should be strictly enforced), sent to the construction unit and the construction unit, copied to the relevant units. And be archived.
2, if there are different views through consultation still can not be unified, should be reported to the construction unit to decide.
3, on the meeting of the meeting decided to have to make design changes, the original design unit by the design change management procedures to modify the design, general issues by the supervising engineer and the construction unit after the finalization of the construction unit, to the construction unit to implement: major issues reported to the construction unit and the higher authorities and the design unit *** with the study to solve. Construction unit to be constructed all the project design drawings, must go through the design and drawings of the review, or not to start. Has been submitted and will review the construction drawings under the form of meeting minutes as a confirmation.
