With the rapid development of China’s economy and the continuous progress of science and technology, all walks of life in China ushered in more new development opportunities. Especially, the road transportation industry, which is a kind of people’s travel, has ushered in a new development height in China. Highway and bridge construction is not only conducive to promoting people’s travel demand, but also conducive to accelerating the communication and contact between regions, providing a strong guarantee for regional economic development.
  It is of great significance for the development of highway bridge construction to further strengthen the management of highway bridge construction and maintenance and ensure the orderly progress of highway bridge management and maintenance. It is necessary to do a good job in the comprehensive evaluation of bridge structure and timely and scientific repair of highway bridge diseases on a regular basis. Only in this way can the maintenance difficulty of highway bridge be further reduced and the maintenance cost be effectively controlled, so as to realize the scientific and reasonable control of highway bridge maintenance.

  In the process of building highway bridges, according to the actual situation, the use of construction management, maintenance, reinforcement and maintenance technology is conducive to the implementation of engineering construction, and avoid the emergence of quality problems in construction. Moreover, it can also extend the service time of highway bridges to a certain extent and provide a good guarantee for the safe travel of the masses. Therefore, the construction unit must implement these technologies in order to ensure the improvement of the project quality when carrying out the construction of highway and bridge.

As the construction management personnel and maintenance personnel, they should clarify their own responsibilities, formulate and implement the construction technology management methods in combination with the basic situation of project construction, strengthen the construction maintenance work, and timely repair the existing quality defects. Therefore, it can improve the highway engineering construction technology management level, ensure the maintenance construction quality, and make the highway engineering in good performance and running state. Finally, it will promote the quality and benefit of highway engineering construction, extend the service life of highway engineering, and provide guarantee for the safe and smooth passage of vehicles.

      公路工程施工中，加强施工技术管理，采取有效的施工养护方法是必要的。作为施工管理人员和养护人员，应该明确自身职责，结合工程建设基本情况，制定并落实施工技术管理方法，加强施工养护工作，及时修复存在的质量缺陷。从而提高公路工程施工技术管理水平，确保养护施工质量，让公路工程处于良好性能和运行状态。最终促进公路工程建设质量和效益提升，延长公路工程使用寿命，也为车辆安全顺利通行提供保障。
       现代化公路建设离不开公路桥梁建设，其承载着繁重的运输负担，为城市化建设做出了重要的贡献。公路桥梁在运输事业中具有较高的价值，为保证公路桥梁的安全性、耐久性，还需不断加强和完善公路桥梁施工技术管理，提高公路桥梁养护水平。

Engineering construction products are complex and diverse, and a lot of manpower, financial resources, material resources, machines and tools need to be invested in the construction. At the same time, according to the characteristics and scale of the construction object, geological, hydrological and climatic conditions, drawings, contracts and the supply of mechanical materials, we need to make full preparations for the construction, construction technology, construction methods and schemes, so as to ensure the technical and economic effect and avoid accidents, which puts forward higher requirements for the engineering construction management and technical personnel. Highway engineering construction workers are the most basic technical and organizational management personnel to complete the highway engineering construction tasks, and they are the organizers and managers of the production line at the construction site. They should command and coordinate the basic technical personnel and labor service personnel at the construction site, so they should strengthen the training of key construction technology knowledge.

  The implementation of highway engineering supervision system is an important part of the reform of highway infrastructure management system in China, and is an effective measure to improve the investment efficiency and construction management level. With the rapid development of national highway, the demand for highway engineering supervision technical personnel is increasing. It is urgent to cultivate a certain number of qualified highway engineering supervision personnel. The main task of the supervision in the construction stage of the project is that the supervision engineer must grasp the "five control, two management and one coordination" work from the perspective of organization, technology, contract and economy, that is, quality control, safety control, environmental protection control, cost control, progress control, contract management, information management and organization coordination.

工程建设产品复杂多样，施工中需要投入大量人力、财力、物力、机具等，同时，需要根据施工对象的特点和规模、地质水文气候条件、图纸、合同及机械材料供应情况等，充分做好施工准备、施工技术工艺、施工方法方案等，以确保技术经济效果，避免出现事故，这就对工程建设施.工管理技术人员提出了较高的要求。公路工程施工员是完成公路工程施工任务的最基层的技术和组织管理人员，是施工现场生产一线的组织者和管理者，要指挥、协调施工现场基层技术人员、劳务人员，应对加强关键施工技术知识的培训。
       推行公路工程监理制度是我国公路基本建设管理体制改革的一项重要内容，是提高投资效益和施工管理水平的有效措施。随着国家高速公路的迅速发展，对公路工程监理技术人员的需求不断增加，培养一定数量的合格的公路工程监理人员已迫在眉睫。工程施工阶段监理的主要任务是，监理工程师必须从组织、技术、合同和经济的角度抓好“五控、两管、一协调”工作，即质量控制、安全控制、环境保护控制、费用控制、进度控制、合同管理、信息管理和组织协调。

After 40 years of development, China’s engineering cost consulting industry has broken through the traditional calculation business of cost consulting (estimation, budget, budget, settlement, final accounts, etc.). It gradually extends the business scope of the cost consulting industry to the early stage of decision-making and the late stage of completion, such as expanding the investment decision in the early stage of decision-making, judicial appraisal after completion, cost audit and audit, financial review and other businesses. 

  From the main business scope of engineering cost consulting enterprises and the proportion of different businesses in the business income of enterprises, it can be seen that although the scope of engineering cost consulting services products of each enterprise is roughly the same, most enterprises still involve some basic business, but most of them take the whole process engineering cost consulting service as the main profit point. These profit points are in line with the current market demand. More high-end engineering cost consulting services, such as judicial identification and arbitration of engineering cost disputes, have attracted a certain degree of attention, but the market demand for such consulting services still needs to be expanded.

中国工程造价咨询业经过 40 年的发展， 已经突破了传统的造价咨询的算量业务（估算、概算、预算、结算、决算等），逐步将造价咨询业的业务范围向决策前期和竣工后期延伸，如拓展了决策前期的投资决策，竣工之后的司法鉴定，造价审核及审计，财政评审等业务。
       工程造价咨询企业的主要业务范围以及不同业务在企业营业收入中所占比重可以看出，虽然各企业的工程造价咨询服务产品涵盖的范围大致相当，大部分企业仍涉及部分基本业务，但大多以全过程工程造价咨询服务为主要赢利点，这类赢利点与目前市场需求是吻合的。更为高端的工程造价咨询服务，如工程造价纠纷的司法鉴定，仲裁等，已经引起了一定程度的重视，但这类咨询服务产品的市场需求仍需拓展。
