With the development of modern society and the improvement of people's daily living standards, the technology and technology of building construction are becoming more and more perfect, and the technical content and artistic appreciation level are also constantly improving. The progress of building construction technology has promoted the development of urban architecture in the direction of large-scale, multi-functional, high-rise, underground and artistic. Small cities in the past have gradually become big cities, and towns are also transforming into cities. At the same time, multifunctional landmark buildings with artistic and national characteristics have appeared in cities. The appearance of landmark buildings also symbolizes the improvement of architectural level, people's living standard and appreciation level in a region, and is also a milestone sign of urban development.
In recent years, many buildings with unique artistic images, such as Ordos Museum, Ordos Exhibition Hall, Ordos Grand Theatre and Ordos Library, have been built in Kangbashi New District of Ordos City. They are novel in structure, exquisite in appearance and complete in function. It must be said that they are a promotion of design and construction technology, the application and embodiment of high-tech and new materials, the artistic masterpiece of the new era and the milestone of the construction industry. All these have to make people admire the progress of modern building technology, the improvement of management measures and the development of construction technology. Generally speaking, the construction of emerging buildings has the characteristics of complex and changeable structure, many new technologies and processes, frequent overlapping of processes and close connection of construction processes. However, behind every kind of building, there are all kinds of hard work, careful management and hard work of every construction worker.
HVAC engineering is the blood of the whole building system and an indispensable part of the building, which is directly related to the overall use and operation of the whole building system. How to strengthen the cooperation and coordination between HVAC engineering and the whole building construction, and how to reasonably arrange the intersection and cooperation between HVAC engineering construction and other majors is a very important thing. Reasonable arrangement of working face, reasonable coordination of working procedures and reasonable control of the construction quality of HVAC project are directly related to the progress of the whole project.
Indoor HVAC engineering can be roughly divided into water supply and drainage engineering, heating engineering, ventilation and air conditioning engineering, fire fighting engineering, etc. In the process of building construction, HVAC installation is closely related to civil construction, which directly affects the total construction period of the whole project, and its completion quality directly affects the safe operation, energy-saving effect and use function of the building after it is put into use, including the comfort, safety and efficiency of people's work and life.
Modern project management and control requires the project manager to have not only profound professional knowledge and rich management experience, but also constantly master the technology and application of new technologies, new materials, new equipment and new processes that are developing rapidly now. In short, managers should keep learning and exploring in practice. With the rapid development of science and technology today, combined with the problems existing in HVAC construction of high-rise buildings, this paper discusses the reasonable development road of HVAC construction technology management.
1. Do a good job in bidding for HVAC engineering.
Engineering bidding plays an important role in engineering projects. For a HVAC engineer of the construction party, it is necessary to have a comprehensive understanding of the whole bidding process. Bidding and determining the project cost are very important. Engineering cost management personnel must timely and accurately grasp the information of HVAC materials, equipment models, specifications, suppliers of origin, etc., and master the basic situation of the local construction market labor force when compiling the bidding documents. Investigate the general situation of the project in detail, and judge the possible situations and risks in the project construction according to experience. And you need to read the drawings carefully, do a good job of sorting out the process, materials, equipment, construction technology and construction boundaries that are not clearly stated in the drawings and give a clear answer.
To do a good job in bidding, we must also master the relevant contents of project budget and cost control, fully grasp the terms of the signed contract, and realize the importance of this work. To prepare for the bidding stage, the project manager is required not only to have the skills in technology, cost and materials, but also to have comprehensive management ability and far-sighted market awareness.
2. The quality and working ability of HVAC project management personnel.
First of all, as a qualified HVAC engineer, he should be highly responsible for the technology, progress, quality and safety of HVAC engineering, carry out standardized construction in strict accordance with relevant national norms and laws and regulations, give full play to his professional level, and do a good job in the management of HVAC engineering in depth and in detail.
A qualified HVAC project manager must first have comprehensive professional knowledge. Water supply and drainage and HVAC are two completely independent majors, but now real estate companies are generally managed by one person in this respect. Therefore, as a HVAC engineer, you should be familiar with the technology and construction specifications of water supply and drainage and HVAC. At the same time, we should also master the relevant regulations of relevant local departments. With the continuous progress of society, materials are constantly updated, and some new technologies and requirements are constantly integrated into the construction. These regulations cover a wide range and are updated quickly, which largely guides the construction and acceptance of local projects.
3. Problems that should be paid attention to in the stage of design review and blue prints.the design.
Design review and design with blue prints.the design are the most important preparations before construction, the best platform for communication between designers and managers, and the important link of technical disclosure for designers. If the work is not rigorous and serious, it will have a great impact on the later construction, and even bring great economic waste and unnecessary losses. Design review and blue prints.the design include two aspects: one is the discussion and research on the applicability and economy of each system; The second is the technical review of each system.
For HVAC major, the products designed and selected should be open, with strong compatibility and large market share, which is convenient for system expansion, interconnection and information sharing. According to the specific functions of the project, define the functional orientation of the project to avoid the phenomenon of lagging design and construction.
The design should not only reflect the economy and applicability of the project, but also reflect the rationality and advancement of the system technology. Whether many mature and advanced technologies and materials are embodied and used in this project. Avoid increasing project investment due to conservative and backward design.
Review whether the design drawings conform to relevant specifications or technical quality standards, and whether the design is reasonable and optimized. For example, several points should be paid attention to in drawing review: 1) Whether the position and elevation of the embedded casing are reasonable; 2) Whether the parameters of power equipment are consistent with other related disciplines. 3) Whether the location and elevation of HVAC equipment and pipelines are reasonable and easy to install, so as to avoid crossing and horizontal crossing with other disciplines. 4) Whether the reserved casing and holes are properly laid out, and whether the elevation and size are clearly marked. In a word, there is still a lot of detailed work to be done in drawing review. Design review and blue prints.the design are important preparation stages before construction, which should be highly valued.
4. Quality control of HVAC engineering
Engineering quality is the core issue of the project, and it is a matter of principle, which is related to the interests of all parties. The quality control of HVAC engineering should be pre-control and process control.
4. 1 material and equipment control. The quality of materials and equipment used in the project directly affects the quality of the project. Without good materials and equipment, there will be no high-quality engineering quality. Select high-quality materials and equipment. First, in the long-term procurement process, gradually eliminate some suppliers with poor reputation and poor quality, and choose suppliers with good market reputation and large scale as long-term partners.
4.2 Organization of construction personnel. Good engineering quality is completed by high-quality and high-level construction personnel, which requires the assessment and evaluation of construction teams and personnel before construction, and the scientific and reasonable organization of construction personnel. Special types of work should be certified, but not partial to the certificate. Combined with the actual situation of the project and the actual operation level of the personnel, everyone's ability can be fully and effectively played.
For the overall technical disclosure of the construction team and personnel, due to the high mobility of the construction personnel, the disclosure should be carried out in stages according to the progress of the project. Explain the current actual specifications, operating procedures and sequence. Understand the data tables and related technical documents, requirements and standards required by the project. Check and confirm the materials and equipment used in the project to create conditions for the next work.
4.3 Quality control in the construction stage. The construction stage is an important link of quality control. It must be carried out according to the design drawings and relevant technical documents, in accordance with the current national HVAC engineering construction and acceptance specifications, local regulations and relevant documents of engineering construction, and the approved construction organization design (construction technical scheme). The drawing problems found in the construction should be put forward and handled in time, and the design is not allowed to be changed without authorization.
Strictly implement standardized operating procedures, process standards and engineering construction procedures, and strictly implement the handover system of construction process. The post division of labor is clear, the responsibility is implemented to people, and everyone involved in the construction should have a sense of responsibility. Concealed works and key processes must be accepted by the construction, construction and supervision units. In special circumstances, please ask the competent department for on-site guidance and make hidden records and other related materials.
5. Safety work of HVAC engineering construction
Adhere to the policy of "safety first, prevention first", carry out safety technical disclosure and three-level safety education for construction personnel, prepare safety technical measures and safety organization measures for this project, and set up full-time safety officers.
The construction team is required to make safety disclosure according to the work arrangement of the day before going to work every day. Safety tools and facilities should be in place.
Project management and control is a complex and profound subject, which has been discussed and studied by several generations of construction workers. Although the form and content of project management are basically the same, the results are different. This requires a comprehensive, systematic and scientific management model and organizational structure. Project management is a dynamic management, not a static management.
With the progress of society and science, new contents are continuously injected into engineering, and the previous experience management is gradually eliminated. With the upgrading of engineering personnel, engineering materials and equipment, engineering technology and construction technology, the methods and contents of project management are also updated, and more and more scientific and technological contents are injected into management. Engineering management has become a discipline, which needs more people to participate in the research.
As project managers, we should abandon outdated stereotypes and actively absorb new and more scientific knowledge and apply it to our work. A new generation of project managers should keep pace with the times, conform to social development trends and trends, and actively explore and innovate.
