On the management of multi-storey residential building construction?

The following is the construction management of multi-storey residential buildings brought by Zhong Da Consulting for your reference.

The housing construction in China is facing the situation of sustainable development, and the housing industry has become a pillar industry and a new growth point to drive the development of the whole national economy. How to adapt to the requirements of the sustainable development of the current housing structure system puts forward new goals for housing construction management. Based on the projects of buildings A, B, C, D, E and F of Maoming Jian Hong Real Estate Development Co., Ltd., this paper talks about personal understanding of multi-storey residential construction management.

Introduction to 0

In China, residential buildings are divided into three types according to floors: low-rise, multi-storey and high-rise. In the General Principles for Design of Civil Buildings (GB50352—2005), China clearly stipulates that the 1 ~ 3 floor is a low-rise residence. 4 ~ 6 floors are multi-storey houses; 7 ~ 9 floors are medium and high-rise residential buildings; 10 or above is a high-rise residential building. Here we focus on the construction management of multi-storey residential buildings with pen and ink.

1 characteristics of multi-storey residential buildings

As mentioned in the introduction, multi-storey houses generally refer to houses with 4-6 floors, and vertical traffic is solved by public stairs, which is a very representative urban assembly house. Multi-storey houses account for more than 90% of newly-built or under construction houses in Chinese cities. The advantages of multi-storey buildings are: first, it saves land compared with low-rise buildings, and at the same time, it has a shorter construction period than high-rise buildings, and can be completed within one year after construction; Second, the pool area is small, and there is no need to increase investment in public walkways, elevators, high-pressure pumps, etc. Like high-rise residential buildings, and the property fee is also low, and the overall cost performance is high; Third, the structural design is mature, usually using brick-concrete structure, building materials can be made on site, and can be industrialized and standardized in large quantities. Therefore, multi-storey houses are low in cost and moderate in price, and are easily accepted by ordinary consumers.

2 Multi-storey residential building structural system analysis

The structural system of multi-storey residential buildings mainly includes the following three categories: first, the multi-storey building system with concrete hollow blocks, but its main problem is that rainwater easily penetrates through the cracks in mortar, and if plastering is carried out on both sides, the plastering amount will be greatly increased; Moreover, plastering on smooth blocks is very difficult and easy to empty and crack; Second, the frame light plate structure system, the structure is mostly reinforced concrete frame structure, and the internal and external walls are non-bearing walls. The internal and external walls can be made of ceramsite hollow blocks, aerated concrete blocks or other non-clay blocks, ceramsite concrete lightweight double-sided smooth noodle boards and 3E boards; Third, the reinforced concrete shear wall structure system, the internal and external walls are cast-in-place reinforced concrete walls, and a variety of supporting external wall insulation systems have been developed. In this structural system, the external wall can also be made into prefabricated wallboard, which can be installed on site after prefabrication.

3. Summarize the particularity of multi-storey residential building construction management

3. 1 local quality problems are equal to all quality problems because multi-storey residential projects involve

As far as the personal interests of many residents are concerned, both the owners and residents attach great importance to the project quality. In the construction, even if the quality of the project is well controlled, if there is a little mistake in one place, it will be all the problems for the residents. This requires late management to be too meticulous and excellent.

3.2 The problem of mutual restriction of various types of work, a link that is not well thought out, will have a chain reaction.

Should affect another link, or more links, resulting in uncontrollable negative effects. If the process sequence is not handled properly, it will affect the protection of finished products and even bring hidden dangers to the whole project quality.

3.3 The construction surface is too scattered because there are many walls and rooms in multi-storey houses. After the construction holes are blocked, the same floor is not connected, which often leads to inadequate construction management and problems.

4 How to manage multi-storey houses well

4. 1 The importance of making a good construction plan should be based on the characteristics of the whole project.

The opposite construction scheme. It should include: construction methods of key parts, process arrangement, insertion time of different types of work, pre-control measures prone to quality problems, and finished product protection measures. In project management, only by grasping key issues and controlling management can we shorten the construction period, improve quality and increase economic benefits. The cost of engineering change and design change accounts for nearly 10% of the whole project cost, and sometimes even more. In the process of construction, all parties may put forward various requirements beyond the requirements of the original design drawings, or they are inconsistent with the actual situation due to poor design considerations. These changes will inevitably lead to the increase of the project cost, and may also lead to the situation that the project cost is difficult to control. At present, most multi-storey residential projects have broken through the control.

4.2 Do a good job in multi-storey residential construction project management, but also pay attention to supervision. The supervision engineers of engineering supervision are all experienced engineers and technicians. They can put forward many positive suggestions to reduce the project cost in the process of design and construction supervision, especially when it comes to whether to make design changes or engineering changes in the construction stage, they can often make reasonable and correct choices according to their own technical advantages, which many representatives of construction parties cannot do due to their experience, experience and technical limitations. In the process of construction. Due to the different positions and viewpoints of Party A and Party B, sometimes there will be some situations that affect the normal construction. As an impartial third party, the supervision unit can coordinate the relationship between the two parties in the construction process to ensure the normal construction of the project, which can provide favorable conditions for the completion of project cost control.

Research on Construction Management Control Method of Multi-storey Residential Building

5. 1 Measures for quality management of multi-storey residential building construction should formulate corresponding quality acceptance standards according to the quality objectives of multi-storey residential building projects, and make the quality acceptance standards of enterprises higher than the national acceptance standards. Strictly control the quality of materials. The purchased materials shall meet the national standards (including environmental protection standards) and design requirements, and the material acceptance system shall be strictly implemented. Ensure the quality of the main structure. The quality of the main structure is related to the quality and safety of the whole project and the life safety of every worker. Therefore, the quality of the main structure must be guaranteed. Pay attention to the quality of decoration. In the stage of construction and decoration, it is necessary to overcome common quality defects and handle the details well. The decoration level should be excellent, innovative and distinctive. Do a good job in the construction of key parts such as basement, first floor, top floor, roof, bathroom, stairs and walkways. We should actively promote the application of new technologies and materials. With the progress of science and technology, new materials and technologies are constantly emerging. Construction enterprises should grasp this information in time and actively apply it to the project.

5.2 Cost management method of multi-storey residential building construction The cost control of multi-storey residential building is to guide, supervise, adjust and limit the manpower, material resources and expenses consumed by production and operation in the process of project cost formation, and control all production expenses within the planned cost range to ensure the realization of cost objectives. The project manager is the first person in charge of project cost control, so he should grasp and analyze the profit and loss situation in time and take effective measures quickly.

5.3 Multi-storey residential building construction safety management measures should conclude a safety responsibility book. In the event of a safety accident, responsible persons at all levels and teams and groups should bear certain economic responsibilities. Ensure that safety facilities are in place. Investment in safety facilities can't be saved, especially after enterprise restructuring. In the event of a safety accident, the loss is far greater than the cost of your safety investment, which has a great impact.

On the basis of the existing management level of multi-storey housing construction, to further improve the management level, a more effective and scientific management system must be established from the technical and personnel systems.
