1 bidding management and contract management
Referring to the requirements of each bidding specification, should be clear and specific model, constituting a fixed form of text format, especially business documents. The specific content of the bidding work should be as detailed and comprehensive as possible, equipped with a complete list, to prevent the problem of omission. For the interface, especially the external interface should be described in detail, to achieve a clear division of labor, to ensure that the interface is clear. For the interface location, should ensure that the interface relationship with the reasonable consistency of the bidding documents, to prevent duplication of bidding problems and omission phenomenon. In addition, effective bid evaluation methods should be adopted in practice. For example, cost-effective analysis, the introduction of technical shortlisting methods. It should not be blindly managed through the low price winning method. Enterprises with ability, excellent qualification and reasonable price should be attracted in, instead of choosing enterprises with low price but no ability. Staff should fully understand the content of the contract and grasp the relevant provisions. Clarify the integrity of the contract itself. Whether or not it reflects economic efficiency, easy and easy contractual matters, should be implemented with full force.
2 Design Management and Supervision Management
Design management should ensure that reference to unified design standards, a clear understanding of the specific audit matters, content, enhance the reliability and practicality of the design and planning. Comprehensive pipeline planning stage, should do a good job in the overall analysis of the relevant system application of all kinds of facilities, tools are taken into account and clear layout principles. Practice should ensure that the entrance and exit ventilation devices, ground lighting layout density, substation low-voltage control switchgear, electric box number setting, circuit control, power distribution box device switch, water supply and drainage pipe profiles, such as specifications, models, standards of effective unity. The same power supply design stage, should also pay attention to the power supply facilities located above the installation of air ducts, especially located directly above the location of the installation of air outlets easier due to the constant fall of condensation of dew leading to equipment systems caused by the failure of the problem. In addition, should prevent the transformer and low-voltage switchgear is not located in the same layer so that the length of the busbar is too large, strict prevention and control of fault phenomena. For the traditional capacitive compensation system function should be refined research and analysis, effective response to its inability to adapt to the current subway engineering reality of the problem of operating conditions. For the integrated grounding system lead terminal should be good anti-theft design, improve the overall planning and management level. In addition, the subway project design should be strengthened as well as on-site management personnel of the integrated control, to prevent the existence of contradictions or omissions in the design drawings, the construction progress as well as the formation of the comprehensive quality of the adverse impact. Entering the field staff should have a comprehensive understanding of the content of the drawings, master a wealth of professional knowledge, timely and rapid on-site command and effective scheduling management. Prevent the problem of arbitrary replacement of designers to ensure that the continuity of the metro project site design, effectiveness of support, so that the functional requirements reflect good consistency. Supervision management should ensure that the post staff is fully equipped, according to the contract standards for operation. At the same time, it should be ensured that the supervisory staff has rich experience and excellent qualification level, and control the arbitrary turnover of personnel. The personnel who do not fulfill the work according to the contract should be severely punished. The obligations of the supervision and management work should be clearly defined, and the rights should be clear, reflecting the legal nature of supervision and authority, to ensure that the supervision is truly on behalf of the owner to play a supervisory function.
3 Owner management and joint management
Owner management should ensure that the metro project planning is practicable, to develop a reasonable construction period target, to ensure that the various processes are compact, to prevent the reverse construction problems. Preliminary should be fully prepared, three pass a leveling treatment, improve the owner's decision-making, related coordination work. It should pay attention to the construction management of nodes and key lines, ensure the reliable stability of the organization as well as the staff, and constitute a consistent and clear contact table. In addition, a high-quality system operation service environment should be created to prevent equipment failure problems, improve interface management, and do a good job of site audit and survey. Contract provisions should be strictly enforced to minimize changes, and design liaison and submission review should be carried out. For sub-projects and stage tasks should be detailed verification, acceptance management and after-sales service, sign a warranty agreement. In addition, the third-party consulting unit can be prepared jointly with the work program and emergency plan, constituting guiding materials. Should be based on the reality of the subway project, the development of joint adjustment work principles, specific guidelines, task time standards, etc., clear test items, specific workflow, etc.. Simulated disaster conditions should be aimed at the specific arrangements and organization of the exercise, clear responsibilities of all parties to ensure the smooth implementation of the task of the joint adjustment, the realization of the subway system as a whole comprehensive joint. In short, it is particularly important to do a good job of subway equipment system engineering construction management. For each segment of the work characteristics, connotation and role, we should develop a scientific and effective practice management strategy to really ensure that the subway service operation of smooth, orderly, comfortable environment, enhance the overall quality level of engineering construction, to create a good quality, cost-effective, as well as the effectiveness of the schedule, to achieve a good and fast overall development.
