In the new era and a new situation, the construction Engineering quality supervision on the business staff, higher quality requirements, every supervisors only enrich the knowledge in order to respond freely to the rapidly changing society, in order to ensure that work to enhance the quality of this article briefly for an overview of bridge Engineering supervision, and how to do a good job of process control, ensure the quality of their opinions, and finally from the supervising engineer in the construction process should pay attention to the elaborate bridge project quality supervision.

An overview of bridge Engineering supervision
Construction Supervision Organization is in addition to construction, the construction unit is an important addition to the main responsibility in the project implementation process, to effectively carry out safety supervision responsibilities, ensuring that the project investment, progress, quality objectives to achieve the basic work, but also to avoid an important part of major security incidents, therefore, on the road and bridge Engineering supervision unit to implement effective safety oversight and strict control of construction site for the elimination of security risks, to avoid casualties has an important role. Project supervision is the supervision unit entrusted and authorized by the owners, according to the regulations and supervision of contracts and other related construction contracts, construction of the project to conduct a comprehensive monitoring and management, namely, the supervision of projects from the three control (quality, schedule investment, two management (contracts, Information, a coordination (for all parties involved in the project organization and coordination. construction supervision is the use of supervisors their construction knowledge, skills and experience to provide supervision and management services to owners, the purpose is to strive to make project in planned investment, completed within schedule and quality objectives used, it does not directly carry out production activities, can only strive to achieve the project objectives in the supervision process, supervision engineers assume service responsibilities.

2 do a good job of process control to ensure project quality
Quality control is the bridge project quality management model in the important part is the core of supervision, through rigorous scientific careful supervision, prompting the construction side to ensure the quality, so as to create fine works and works lay the foundation for safe operation. Supervision engineers must first draw up the supervision plan, clearly in the whole process of supervision in what to do, how to do, when to do a series of problems, so that each phase of the supervision activities onto the standardization track. Second, through the whole process of supervision, implement a comprehensive quality control measures to ensure the quality of the project, the whole process of implementation of the system, people, machines, goods, money, rings implementation of a comprehensive quality control. Third, we must strengthen supervision of key road sections or parts, such as through joint field office form of timely resolution of critical sections and parts of the problems, the key to high-quality construction to bring the overall project progress.

2.1 carefully review the design drawings
Supervision of the project department first carefully study the design drawings, reading, the problems found in the plan approval and construction unit of the problems found in the summary, tests at the design, writing, design units answer it and get a written response to to ensure the smooth progress of construction accuracy.

2.2 Quality Control
2.2.1 First, construction design and location of catch to start the application and construction programs. Supervision approval of construction design and construction program is part of the basis for the construction contractor, is also the basis for assessing contractor performance behavior. Requires the preparation of the construction unit of the construction organization site design and construction program, each one of them serious, meticulous and timely review, strict control, where non-compliance with technical specifications and schedule objectives, the construction unit repeatedly modified until it meets the regulatory requirements to minimize losses and avoid the project, to optimize the program, identify the critical tasks and critical path.

2.2.2 Project location. Engineering positioning control points are: the contractor should have qualified surveyors, measuring equipment and reasonable technical measures to ensure the accuracy of positioning project. Supervision Department of eleven items related to personnel qualification check measurements and measurement certificates certificate of inspection equipment to ensure that surveyors certificates, instruments detected both within the validity period, from the source to ensure accuracy.

(A reference point accuracy. Reference point positioning accuracy is an important guarantee for construction by unit owners and management of the organization, supervision and construction of Surveying and Mapping and the units in the field reference point for the transfer of piles, the reference point measured by the construction supervision engineer units and retest closed and encrypted according to the project site conditions, a fundamental guarantee for the whole project of positioning accuracy and the use of demand.

(2 construction layout of the controls from the plane and three-dimensional spatial location full control parts of the loft control measure must be approved by the supervising engineer, after review and correct before the next process of the construction.

(3 materials for inspection. Into place with each batch of steel, and cement required to take the specimen to a qualified laboratory testing, supervision and witnessed more than 30% sampling, laboratory experiments provide the basis of test reports, to related standards in order to allow the use Links to free download http://www.hi138.com
3 in the basic construction phase, the supervision engineer should be
3.1 pre-construction, supervision engineer should review the contractor's construction team and technical staff of professional quality that meet the relevant requirements, be allowed to start.

3.2 According to the design drawings to put the right line. Personally supervising engineer to the site inspection should be, so items of work related to the route and structure of the connection problem, not the slightest slack, the error in the specification to be within the allowed range.

3.3 in the basic construction, the supervising engineer to focus on the changes in geological conditions of structures due to the design of survey and drilling of the unknown, or because of other natural conditions may cause on-site conditions and design drawings are to match the geological data, it must timely and Design on behalf of (or design in consultation, design changes made to take the appropriate engineering measures, otherwise the project may cause great troubles, the consequences will be difficult to remedy.

3.4-based project is a covert project, therefore, must adhere to strict site supervision principles. Conditional basis to be buried before the more supervision by a professional engineer to the site approval, guarantee the timely detection of changes in geological conditions and the process of construction defects, and the construction process of each section, to photograph it, to prepare Information, as a case of unexpected accidents basis for the responsibility to be punished.

3.5 for the expansion base, a large number of concrete pouring work, sometimes working with the laying of steel, therefore, from the excavation pit, set the cofferdam, drainage, erect template to the concrete pouring work requires a certain level of Technology, as site supervision engineer should be present at every level acceptance, and for individual parts (such as the edges of the concrete vibrated work should be of particular importance for the site are reinforced, the reinforcement size and spacing to do the inspection.

In short, with economic development, China's highway project quality requirements continue to increase, therefore, each supervising engineer, to enrich their business knowledge, always with enthusiasm to work to meet the country's road transport industry .
