2.3 Due to the limitation of installation quota, it is difficult to grasp the actual situation.
The current installation quota standard has adapted to the actual needs of the new market, and it can not reflect the current market quota.
Therefore, the relevant reviewers must analyze according to the current calculation methods and data sources, focus on the authenticity of the construction and installation quantities, and analyze the on-site quantities to see if there are any errors.
2.2 Traditional process is gradually replaced by new process.
Therefore, residents attach great importance to the project.
The most obvious is that the cost is often over estimated.
With the rapid development of economy, traditional process products have been gradually replaced by new process products.
There are many kinds of heating materials needed in HVAC projects, including aluminum products, steel products, aluminum copper composite products, copper products, aluminum steel composite products, etc.
When calculating the cost of a construction project, it is necessary to first break down the project, calculate the cost of each segment separately, and then summarize the calculation results.
3.2 Effective establishment and centralized strengthening of project quantity management In the process of construction and installation projects, the increase of project cost is often caused by the temporary increase of project quantity.
The construction and installation works are complex in content, diverse in technological means, and short in project time.
Due to the limitation of installation quota, the development of construction and installation is not very optimistic.
When calculating the specific cost, each part needs to be calculated separately and then integrated.
That is to say, the whole project can be divided into several parts.
With the gradual improvement of the building level, the acceptance requirements for architectural design are getting higher and higher, and the acceptance will be carried out according to the international and scientific standards.
The expense withdrawal specifications for construction and installation projects must be effectively implemented in accordance with the contract contents and relevant provisions.
The errors in subsequent quantities are divided into positive errors and negative errors.
Because the prices of different materials are different, the calculated prices will vary greatly due to the different types of materials.
For example, copper pipes, aluminum plastic pipes, galvanized steel pipes and copper plastic composite pipes commonly used in drainage projects in the past have been gradually replaced by modern PVC pipes and stainless steel pipes.
In addition, it is also necessary to effectively follow the economic system laws of the market as a whole to prevent more contradictions and ensure that the overall audit is fair and scientific.
In addition, new materials and manufacturing processes have emerged in the market one after another, and they have also been widely used.
In this process, the rates and conversion coefficients of relevant projects shall be strictly checked and the overall expenditure of each project shall be paid attention to to ensure rationality.
Third, more detailed and comprehensive analysis and review should be carried out for the bids of different bidding units, special marks should be made for those obviously lower than the market price, missing items or ambiguous contents, specific settlement methods and specific precautions of project cost should be clearly analyzed in the actual bidding process, and written commitments and guarantees should be made, In order to better enhance the value of the bidding documents and avoid unnecessary disputes in the future construction process.
2.4 The construction and installation project cost has the characteristics of subsection and combination.
The steel products also include plate type and tube type.
2 Main characteristics of construction and installation project cost 2.1 There are many types of construction and installation projects, mainly including drainage projects, HVAC projects, lighting projects, etc.
Key words: architecture; Installation works; Cost management; Analysis 1 Introduction With the overall growth of China’s social and economic system, the field of construction and installation engineering is also developing rapidly, but there are also some problems.
The construction project is closely related to people’s daily life, will have a great impact on people’s life comfort, and is also closely related to the quality of housing construction.
Relevant departments should pay attention to the quality of the construction and installation project cost management, take effective measures to gradually make up for the shortcomings in the current project cost management, so as to promote the optimization and improvement of its management mode, which will be conducive to the healthy and efficient development of the construction and installation project, and promote more economic benefits in the future.
Abstract: In fact, the construction and installation project is the installation of equipment in the residence, usually including heating, drainage, electrical and other equipment.
In the actual management, attention should be paid to the setting of the overall management mode according to the actual site conditions.
Avoid adverse impact on construction and installation cost.
Therefore, in the follow-up project management, if you want to ensure the overall project quality, you must increase efforts in the budget review process, effectively optimize the cost, and prevent the decline of project quality due to cost problems, which will affect the effective development of the project.
3 Key points of EPC project construction and installation project cost budget review 3.1 Do a good job of cost management and control in the bidding process First, in the actual construction and installation project bidding process, we should more comprehensively and carefully review the relevant content and terms in the bidding documents, control the cost from the source, and ensure that the preparation of bidding related documents and organization work are scientific and reasonable..
The construction and installation project cost involves a relatively wide range, belongs to the fixed asset system, and contains very complex contents.
During the installation of construction projects, due to the uncontrollable situation of the market, the budget of important materials must be prepared according to the market price, and the budget implementation adjustment shall be completed during the settlement of the project..
For example, comprehensively review the collection of various fees according to the specifications.
Secondly, the bill of quantities prepared by the price ceiling review unit needs to be carefully reviewed to ensure the scientific and reasonable preparation of the bill of quantities, define a more reliable bidding control price, and do a good job of confidentiality.
