Nanjing University of Technology Construction Engineering Technology Co., Ltd. is a scientific and technological service enterprise based on Nanjing University of Technology, which is restructured from the former comprehensive laboratory of construction engineering of Nanjing University of Technology. It is characterized by construction engineering technology services and focuses on project quality testing, identification and research. The company is headquartered in the Science and Technology Industrial Park of Nanjing University of Technology, and has set up corresponding professional laboratories for building structure, steel structure, wood structure and building energy conservation in Nanjing University of Technology.
The company's testing work began in the 1980s. In 1991, the company passed the qualification examination of the first class civil engineering laboratory of Jiangsu Provincial Department of Construction. In 1994, the company passed the metrological certification of Jiangsu Bureau of Quality and Technical Supervision. In April 2009, the company passed the accreditation of the national laboratory. In August 2010, the company passed the accreditation of the national inspection agency. The company is a testing agency with A-level credit rating for construction project quality testing in Jiangsu Province, and the first batch of comprehensive first-class energy efficiency evaluation agencies designated by Jiangsu Provincial Department of Construction.
The company's construction engineering structure testing is mainly engaged in testing the safety performance of buildings, structures and masonry structures.
The company has perfect supporting facilities and instruments, including steel bar position tester, non-metallic ultrasonic testing analyzer, optical theodolite, crack depth meter, crack width meter, dynamic strain testing system, stress strain tester, vibration testing equipment and other advanced testing instruments and equipment at home and abroad.
The business scope of construction engineering structure detection mainly includes:
1) On site testing of concrete structure strength (ultrasonic rebound comprehensive method, rebound method, core drilling method, etc.);
2) On site masonry mortar strength test (penetration method, rebound method, etc.);
3) On site masonry strength test (in-situ axial compression method);
4) Thickness test of reinforcement protective layer (NDT);
5) Static load test on structural performance of concrete members (deflection, crack resistance, bearing capacity, crack width);
6) Detection of uplift bearing capacity of concrete post anchorage;
7) Structural deformation detection (tilt, crack, etc.);
8) Concrete appearance quality and defect detection (ultrasonic detection);
9) Deformation and defect detection of masonry structure (cracks, weathering, peeling, verticality);
10) Structural dynamic test;
11) Chloride ion content detection;
12) Electrochemical detection of rebar corrosion;
