1. Improve the design drawings with BIM technology.
With the continuous promotion of BIM technology in China, design units and drawing review units can completely apply BIM technology to design. According to the characteristics of BIM, such as visualization, collaboration and simulation, various professional projects are effectively integrated, and the gaps and conflicts of various professional drawings are checked by means of simulation and collision inspection. At the same time, BIM can also be used for more refined design, improve the quality of design drawings, and reduce design changes caused by design omissions and other reasons in the subsequent construction stage.
BIM is applied to the joint review of drawings, modeling and collision inspection of design drawings of architecture, structure, mechatronics and other specialties, so as to avoid design conflicts between specialties and errors and omissions in design as much as possible, effectively reduce design changes and rework problems caused by design drawings, and thus reduce the cost increase caused by design drawings.
2. Improve the methods and procedures for adjusting the temporary appraisal budget of professional projects.
(1) Real-time adjustment of temporary evaluation budget of professional engineering.
Because the professional projects involving temporary evaluation need to be tendered in the project construction process, the cost of such professional projects can be effectively controlled in the tender stage. The problem of delaying the bidding for professional projects should be adjusted according to the actual situation at the time of bidding.
(2) Two-stage bid evaluation method is adopted.
In the tender stage of steel structure engineering, considering the importance of technical scheme, the bid evaluation adopts two-stage bid evaluation method, that is, the first stage is technical scheme evaluation and the second stage is commercial bid selection. In the first stage of bid evaluation, technical experts are organized to select and score the bidders' schemes. On the premise of meeting the time limit stipulated in the contract, the feasibility of the schemes is seriously considered, and the top three bidders with the highest scores are selected to enter the second stage of economic bid evaluation. In the second stage of bid evaluation, the reasonable lowest bid evaluation method is used to determine the winning bidder in the effective bid quotation.
Through the above measures, not only the temporary evaluation of professional engineering is controlled within the budget, but also the complexity of its construction is solved, which ensures the project to be carried out as scheduled, and also plays a good demonstration role for the subsequent bidding of other professional projects.
3. Establish professional teams and strengthen contract management.
In view of the problems existing in the execution of the project contract, a professional contract management team was set up to solve them. Team members have rich experience in contract management and legal knowledge, and are responsible for the overall management of various contracts of the project, and feed back information to the project leader in time.
In the early days of the establishment of the contract management professional team, the existing contract documents were sorted out and detailed disclosure was made to the project manager, the contract risk loopholes were analyzed, and corresponding management measures were put forward in view of the existing contract problems, which laid the foundation for the improvement of the subsequent professional subcontracting contracts. During the execution of the contract, the team is responsible for supervising the execution of the contract by all construction units. Through the comprehensive collection and analysis of contract execution information and engineering data, the contract execution and contract analysis data are compared and analyzed to find out the deviation. For the problems existing in the execution of the contract, the corresponding management measures are put forward in time to prevent the expansion and recurrence of the problems, and supplementary agreements are adopted to improve the contract loopholes when necessary. In addition, according to the various claims of the construction unit, the professional team will review whether it is established, and the established claim details will be strictly reviewed. At the same time, the professional team should also take the initiative to take counter-claim measures against the progress, quality and safety of the construction unit to safeguard their legitimate interests. Through a series of practices of the contract management professional team, the effective implementation of the contract was ensured, the unfounded claims of the construction unit were reasonably refuted, and certain losses were recovered for the construction unit through counterclaim.
4. Establish and implement a perfect cost management model.
(1) organizational structure optimization of cost management
In order to overcome the problems existing in the cost management mode in the construction stage of large-scale projects, firstly, the project is decomposed and an organizational structure composed of the construction unit, the cost consulting unit entrusted by the construction unit and the construction unit is established. The organizational structure consists of four units * * *, and the members of the organization are cost personnel with rich professional experience. Through project decomposition, the cost management of each major is refined.
(2) Optimization of cost management system
Secondly, combined with the contract documents and cost characteristics of the project, establish and improve various cost management systems, including contract measurement and payment management, materials and equipment management, design change management, on-site visa management, etc. Each system not only stipulates the responsibilities of each unit, but also describes the information regulation, declaration and approval process in detail, making it systematic and operable. For the interior of the construction unit, the management system applicable to the work requirements and contents of each department has been formulated accordingly, and the functions and responsibilities of each department have been clarified, avoiding the mutual shirking of related work between departments.
(3) Develop a cost information management platform.
The construction unit develops an information management platform based on internet websites and smart phones, so that all participants in the project can work together on the platform anytime and anywhere, which is convenient for cost management in the construction stage. In terms of cost management, the information platform has developed modules such as measurement and payment management, design change management and on-site visa management. Each module has corresponding functions, such as measurement and payment management module, which mainly realizes the declaration and approval management of progress payment, and can also set up fund early warning according to the contract to prevent the construction unit from exceeding the progress payment. It can also automatically generate the account of contract measurement and payment, which is convenient for cost managers to quickly understand and supervise the content of contract measurement and payment more efficiently. According to the responsibilities defined in the contract documents and the cost management system, all contractors have been given corresponding authority, such as the construction unit has the authority to initiate measurement and payment, and the supervision unit has the corresponding audit authority.
Each contractor is required to carry out the declaration, review and approval process according to the standardization of the information platform, and which link and handling status of each event can be reflected on the platform. This requires all units to complete in strict accordance with the agreed time requirements, effectively putting an end to the phenomenon of audit delay, which is conducive to the rapid progress of the incident.
To sum up, by taking the above measures to optimize the organizational structure and system of cost management, the cost management mode of project settlement tends to be perfect, the loopholes in the original cost management are repaired, and the cost managers have evidence to rely on, thus curbing some unreasonable cost adjustment documents of the construction unit. With the help of self-developed information management platform and the use of information technology, the cost management process is optimized, so that all participating units can form standardized and standardized cost management, which effectively solves the problem of chaotic cost management.
5. Optimize the management of completion settlement.
(1) Formulate and implement the project settlement plan.
Large-scale complex projects should formulate corresponding completion settlement plans according to their own characteristics. In order to give full play to the control role of settlement in the construction stage and promote the smooth progress of settlement, the construction unit will formulate the settlement plan of this project in combination with the characteristics of KA project. The main contents of the settlement plan include:
(1) Establish a settlement organizational structure composed of relevant personnel of all participating units in settlement work, and clarify the responsibilities and work of this organizational structure;
(2) It is required to adopt the method of installment settlement, and specify the requirements for the settlement preparation of the construction unit, including the division of installment settlement units, installment settlement plan, composition details and requirements of settlement data, etc. Clarify the internal audit procedures and requirements of supervision units, cost consulting units and construction units. Through the implementation of the settlement plan, it is beneficial for the construction unit to collect complete settlement data as required in the construction stage, so as to avoid the subsequent settlement progress being affected by the lack of data.
(2) adopt the method of installment settlement.
The most critical method of phased settlement in the settlement scheme is also one of the important methods to control the project cost. For large-scale complex projects, we can adopt the method of phased settlement, and compare the settlement of phased nodes with the corresponding budget to analyze whether there is deviation. If the previous node settlement exceeds the budget, other means such as quota design and value engineering can be used to control the cost for the subsequent construction content.
In addition, in the installment settlement, the price changes of main materials can be adjusted in time according to the contract, which is conducive to coping with the risk of price fluctuation. The implementation principle of each node settlement is that the construction unit has completed the construction according to the construction drawings and design changes and meets the contract quality requirements, and the node engineering data is complete, so the phased settlement can be carried out. This also requires the settlement auditor to have a certain understanding of the site construction situation, so as to check whether the actual construction situation is consistent with the design drawings.
