(2) Procedures The construction drawings to be reviewed include the self-examination phase, the review phase and the on-site visa phase.
1) The review work of the design drawings is generally presided over by the construction unit, and the design unit and the construction unit will participate, and the three parties will conduct the design review of the design drawings. The design unit explains the design intent of the proposed project and some design technical descriptions; the construction unit proposes questions and suggestions for the design drawings based on the self-audit records and understanding of the design intent. Finally, it is necessary to form the "pattern review and review" officially written by the construction unit, as the technical documents used at the same time as the design documents and the basis for guiding the construction, and also the basis for the construction settlement between the construction unit and the construction unit.
2) On-site visa work for design drawings refers to the construction process, when the conditions of the construction are found to be inconsistent with the conditions of the design drawings, or when the design drawings are to be modified for other reasons, the visa system that follows the technical verification and design changes is used to carry out the drawings. Construction site visa. The pattern modification, technical verification and design change information of the construction site shall be returned to the proposed construction archives as the basis for guiding construction, completion acceptance and project settlement.
3. Study and prepare the construction organization design and construction budget of the project.
4. Complete the construction drawing work and do the drawings supply work.
5. Conduct technical disclosure and technical training.
2. Preparation of the construction site Do a good job in the measurement and measurement of the construction site. According to the site conditions, set the permanent latitude and longitude coordinate position of the field, the level base point and establish the site engineering measurement control network.
Level the industrial square and remove obstacles. Complete the work of "four connections and one leveling" (water, electricity, communication, road and site leveling), and make the sewage discharge ditch smooth.
In case of unclear geological data or need to further understand the geological conditions, the supplementary exploration work at the construction site should be done to ensure the smooth progress of the basic construction and eliminate hidden dangers.
Propose the equipment, equipment, material entry plan, and organize the entry, assembly and maintenance of construction equipment. All construction machines should be inspected and commissioned before the start of construction; do a good job in building materials, structures (components) and products. Field and storage stacking.
Complete the necessary temporary construction work (work shed, material warehouse) and necessary living and welfare facilities (lounge, canteen, etc.) before the start of construction.
Complete various industrial facilities required for construction, including construction site protection and environmental protection; complete necessary welfare facilities; complete engineering preparation for wellbore construction.
Other preparations include concrete mix ratio test, new process, new technology test, preparation for rain or winter construction.
(III) Material preparation Based on the construction organization design and construction drawing budget, prepare materials and equipment supply plans.
Develop a construction machinery demand plan.
The specific materials preparation during the construction preparation stage are mainly the materials and equipment in a certain stage of the initial stage of various construction projects, as well as the equipment, equipment and materials used for construction, including the equipment and construction preparation required for the start of the wellbore, and the steel and wood required for the start of the mine. , cement, indigenous materials, supply of second and third class materials.
Implement the supply channels of the source of goods, and the organization will arrive on time. All kinds of materials should generally have a reserve of 3 months of demand. It is required to ensure the construction needs and avoid backlog waste.
According to the needs of each construction stage, the construction labor demand plan is prepared.
Do a good job in the organization of the labor force. Establish labor organizations and organize personnel to enter the market according to the construction preparation period and the needs of the progress of each project after the official start of construction. Do a good job of deployment and basic training before starting work. It is necessary to go to the main construction team after basically completing the construction preparation work, so as to avoid rushing and causing work.
Do a good job in technical disclosure. The time for construction organization design and technical disclosure shall be carried out in time before the commencement of the work of the unit project or division (item) to ensure that the construction personnel understand the meaning and requirements of the construction organization design and construct and operate according to the construction organization design requirements.
Establish and improve on-site construction and various management systems of labor organizations.
(V) Coordination and coordination work Some construction and living conditions during the construction preparation period (such as water supply, power supply, communication, transportation, sources of indigenous materials, supply of living materials, land acquisition and obstacles for demolition) require local government, agriculture and other The cooperation of the industrial sector can be achieved smoothly. Therefore, striving for external support and doing a good job of external collaboration are two important tasks in the construction preparation period.
Do a good job of subcontracting. For the project content that needs to be subcontracted, complete all preparatory work for subcontracting, including selecting subcontractors and contract signing, drawing supply, site preparation, etc., without affecting the timely start of subcontractors.
Fill in the application report for the start-up in a timely manner and report it to the competent department. Immediately after the approval, the project can be started.
