1. Strengthen the construction of large cost information base and implement dynamic budget management.
First, local cost management agencies should always pay attention to the changes in the cost information market, establish large databases and forecasting models, and scientifically predict the price trends of artificial and main materials (such as steel, cement, sand and gravel) for the reference of budget estimators, and reflect them in the budget estimates to achieve controllability. Previous studies have verified the possibility of building information model (BIM) application and the advantages of data management in the field of engineering cost, but it is rarely used in the practice of engineering cost management, especially in the field of municipal engineering construction. In fact, physical characteristics and functional characteristics are possessed by general building projects, while BIM is expressed in digital form. In the BIM platform, you can fully enjoy the information such as the price trend of the talent machine, and all the decision-making basis of the whole life cycle of the project is more reliable; At each stage of the project, the business responsibilities of each participant are also very clear, which is more convenient for dynamic management.
2. Strengthen the control of design bidding.
Municipal engineering should take "design bidding" as an important means of cost control, take "bidding control price" as the core, constantly strengthen the management of design bidding, comprehensively consider the technical and economic effects, and optimize the best design scheme. After the implementation of "New Bill of Quantities" in July 2003 1 2065438, the establishment of "tender control price" for municipal projects has become a mandatory requirement for state-owned funds to invest in construction projects. It also puts forward higher requirements for compiling accuracy: the error fluctuates between plus and minus 3%; Compared with the fixed construction period, when the compressed construction period exceeds 20%, the "overtime fee" must be clearly increased in the bidding documents.
On this basis, we should first improve the design bidding system, make the bidding environment open, fair and just, and make the design units more willing to participate in the competition; Secondly, in the design bid evaluation, we can invite architectural economists to participate, introduce the "value engineering analysis method" into the design scheme evaluation stage, avoid simplifying the design scheme evaluation index, make various settings, assign weights with reference to the engineering importance, and better compare and select the best design scheme; The third is to strengthen the integration of design and construction, gradually absorb the participation of construction enterprises in the design stage, strengthen communication and coordination, reduce the deviation between design and actual construction, improve the design level, and finally effectively control the project cost.
3. Choose the construction scheme, materials and technology according to the principle of economy and applicability.
From the point of view of project construction organization, it is most important to choose a suitable construction scheme. In the project cost, the construction scheme is also the most direct and important factor.
Usually, there are three elements in choosing a construction scheme: one is to choose the construction method of important divisions (subdivisions), the other is to determine the construction sequence, and the third is to clarify the engineering operation method. Only when the construction scheme is reasonable and controllable can the project cost be reasonable and controllable. So first of all, we should judge whether the construction scheme is feasible and whether the technology is advanced. Secondly, judge whether it is suitable for the project scale; The third is to judge whether it is economical and reasonable; The fourth is to judge whether it is safe. The best scheme is to make a comprehensive comparison according to the above contents to ensure the most economical, safe and applicable. In addition, advanced construction materials and technologies are conducive to improving construction efficiency and speeding up the progress of the project, but whether they are selected or not needs to be correctly evaluated.
4. Reform the charging method of engineering design and explore the incentive mechanism of the construction unit.
At present, there are two options for municipal engineering design fees: one is the amount per square meter; The second is the percentage of the total investment scale.
In fact, in order to seek their own interests, each design institute only wants to make the project bigger, instead of constantly optimizing the drawings, resulting in high project cost. Therefore, it is imperative to reform the charging method of engineering design. In practice, in order to encourage the optimization of drawings, it is advisable to implement the charging method of high quality and good price, and set up the "Design Reasonable Saving Award". In view of the fact that the design drawings can't reflect the overall situation of the site, this paper explores the incentive mechanism of the construction unit and encourages it to optimize the drawings and construction technology, which can not only effectively control the project cost, but also increase profits and achieve win-win results for all parties.
5, the implementation of the construction management network
The construction sequence is reasonable, the repetitive work is less, the progress is fast, and the project cost can be effectively controlled. Municipal engineering involves a wide range, construction units have many cross-operations, coordination is difficult, and repeated construction is common.
In big cities, water supply and drainage, communication and power grid are often excavated repeatedly in the same section. Using computer technology to implement networked construction management will simplify the process. The implementation of network management means that the general contractor makes a feasible construction organization plan, arranges special personnel to make a "network diagram of project progress", and monitors, coordinates and adjusts all the progress in time to avoid repeated construction and congestion.
I believe that after the above introduction, everyone has a certain understanding of the five killers of municipal engineering cost control. Welcome to Zhong Da for more information.
