In recent years, with more and more overseas companies investing in and managing projects in big cities in China, some advanced foreign project management models have followed. In fact, design and construction are separated in foreign countries, and design is divided into scheme design and construction drawing design. Generally, the design of these two parts will be completed by different departments or companies, which will be very professional and the drawings will be very detailed, which will also bring great convenience to the construction. Especially for some high-grade projects, for the convenience of management, Party A requires all construction units to deepen the construction drawings before construction, and the construction can only begin after the deepened drawings are passed. The purpose is to require all construction units to clear up their thinking before construction, digest and mature before construction, avoid mistakes, and uniformly ensure the effect.
The meaning of deepening the design of construction drawing: on the basis of the original design, combined with the engineering site, some places that are inconsistent with the site are modified or redesigned, and the on-site setting-out supervisor is required to guide the on-site construction.
Generally, to do a good job in deepening design, the following steps should be followed: 1. Positioning of plane size; 2. Positioning of facade decoration; 4. Further modification of nodes; 4. Technical disclosure and on-site construction supervision and guidance; 5. Compilation of as-built drawings.
First, the plane size positioning is to require the on-site deepening designers to truthfully reflect on the drawings according to the drawings and site conditions, and make clear the dimensions of all the required decorative parts on the plane. This dimension must be measured on the spot for every part of the site, and the dimensions of all the same rooms or parts should be statistically classified and unified, and each dimension should stand up to scrutiny and be practical. In order to set out these dimensions on the spot, it is necessary to clarify the regional interfaces of different parts, and at the same time, it is necessary to reflect the lines of furniture layout on the ground to facilitate the later construction and find problems.
Second, the positioning of facade decoration is to reflect the decoration on the facade on the wall on the basis of plane size positioning. It is necessary to make clear the position and size of different materials on the wall, which is convenient for construction disclosure, not easy to make mistakes, and can be adjusted in time when there is a problem with the size or proportion.
Third, the node deepening modification is to refine the convergent or modeling parts of different materials, especially some internal structure parts, on the basis of plane size positioning and elevation decoration positioning. Because design drawings are generally not so detailed, they must be detailed to facilitate workers' construction and make no mistakes. Some have to reserve the closing position in advance, analyze the construction sequence, and ensure the rationalization of construction technology.
Four. The technical disclosure, supervision and guidance of on-site construction is to make technical disclosure to the on-site construction administrator and construction team after completing the above three steps, so as to ensure the implementation of deepening drawings, unify construction practices and facilitate management. In the process of construction, designers should undertake quality supervision and construction specifications. If there is any doubt at the scene, it should be solved in time. Assist the project department to manage the project well.
Verb (abbreviation of verb) As-built drawing actually completes the above four steps, and as-built drawing naturally comes out, which is just arranged according to the specifications of as-built drawing to provide real and reasonable data for the final accounts of the following projects. Avoid missing reports as before.
If we can strictly follow the above steps, we will certainly do a good job in deepening the design. As we all know, high-end projects have begun to be assembled, mainly the production and installation of marble, carpet, doors, windows and cabinets. In the decoration content, only wood products, plasterboard walls and latex paint finishes are left in the on-site construction. The competition between quality and price is more and more fierce, that is to say, under the same premise, whoever has more outstanding advantages will be invincible in this market. In addition, with the maturity of market construction, the on-site production is influenced by the surrounding environment, which makes the decoration company produce in the processing plant as much as possible during the decoration process, which leads to what we call the wood veneer assembly construction today.
A, the definition of wood veneer assembly construction:
The so-called wood veneer assembly construction: in the process of decoration, the wood veneer part is deeply summarized according to the actual situation on site, and made into a processing drawing, which is made by the furniture factory according to the processing drawing, and then installed on site.
Second, the advantages of wood veneer assembly construction:
The advantages of wood veneer assembly construction are as follows: 1, quality assurance: because wood veneer is made in furniture factory, that is, wood veneer is made according to the quality requirements of furniture, so it is definitely better than the original factory made on site. 2. Shorten the construction period: Because the veneer is made in the factory, the veneer to be processed can be put into the processing factory in advance at the same time of construction, and the veneer can be installed immediately after the construction of the partition wall and ceiling is completed on site, which can greatly shorten the original construction period. 3, easy to control the cost: wood veneer can be mixed in the factory to control the cost of raw materials, unlike on-site construction because of the large working face, on-site management can not cover everything, which is easy to cause material waste.
Four, the development prospect of wood veneer assembly building:
In China, the construction of wood veneer assembly mainly began in 1990s. The earliest Portman Hotel in Shanghai was mainly built by Hong Kong Dayi Decoration Company. Later, after 2000, there were Four Seasons Hotel in Shanghai, Hongta Hotel in Shanghai, Westin Hotel in Shanghai, Marriott Hotel in Tomorrow Square in Shanghai and Shangri-La Hotel in Pudong. Through this process, more and more projects require wood veneer to be made in the factory, mainly considering that on-site painting is easy to cause air pollution in the building and the quality is unstable. In addition, with the development of the city, fewer and fewer new buildings are built, and the renovation is mainly carried out in the old buildings, which are still open as usual during the construction process. Therefore, the time and noise of on-site construction are strictly controlled, and large-scale on-site construction is not allowed. We can only concentrate on on on-site installation after processing in the processing plant, thus shortening the time of on-site construction. So as to achieve what they say, constantly give people a new look and feel, and increase the attraction to customers.
