NCQ-Center of Certification and Quality
Under coordination by DQN, created in 2009
Establish and maintain the quality management systems: As LECM is an organization providing reliable testing for construction materials of Macau and technical assistance to public and private sector in the field of civil engineering, to ensure the conforming product will only be used in construction project, and provide a trustable backup to public or private section of Macau society in civil engineering field, it is necessary to establish a quality management system which is applicable for LECM, NCQ of DQN is responsible for establishing and maintaining the quality management system and ensuring its’ effective implementation
Coordinate the 3rd party accreditation activities: For the quality management system which is being implemented, NCQ is responsible for coordination of ISO 9001 certification, ISO 17025 and ISO 17020 accreditation, ensuring the effective implementation of such management systems through certification/accreditation and regular assessment conducted by 3rd parties
Conduct product certification and factory production control system certification
The norm such as concrete and cement which are formulated by LECM, is based on the cooperation scheme with DSSOPT, in order to effectively implement such norm and also to enhance the overall quality of construction materials in Macau market, according to 56/ SATOP/98, LECM is authorized by Macau government, to perform the following types of certification based on current norm and standard:
1. Product certification
2. Production control system certification
Introducing certification to product or production control system of factory, ensure the regular evaluation on quality management system and its product’s quality. Furthermore, it will benefit to other departments or centers when making a technical advice and analysis on the use of relevant manufacturers and its products.
Introduction of NCQ’s services
Establishment and Implementation of ISO 9001, ISO 17025 and ISO 17020 For more than 35 years since the establishment, LECM has developed the internationally applicable quality management system (ISO 9001), management system for testing and calibration laboratory (ISO 17025) as well as the management system for inspection body (ISO 17020).

• Certifi cation of factory production control systems
• Certifi cation of products for the construction fi eld
Certifi cation of products
Certification of construction materials that used in Macau market according to the relevant Macau Standard;
It guarantees that the supplied products are in conformity with their specific standards. LECM certificates of cement and concrete are in accordance with the Cement Standard and the Concrete Standard of Macau, respectively. Besides, according to the dispatch from DSOP, LECM is authorized as a certification body for PHC pile product.
Certification of factory production control systems
It guarantees the producer’s capacity to supply products satisfying their specific standards, based on the ISO 9000 standard.
Construction materials and components from certified producers are subject to lighter rules of reception on the construction sites. Besides of the quality management system, the technical part of the certification work (including the certification of ready-mixed concrete, cement, PHC pile, certification of factory production control system for precast concrete pipes and manhole elements) is collaborated with DMC of LECM.
Product certification---Ready-mixed concrete
LECM is authorized by Macau government as a certification body for ready-mix concrete and established the “Certification Rules for Ready-Mix Concrete”. Up to end of 2013, there are 6 local batching plants are certified by LECM.
The recent established Macau ready-mixed concrete Association is composed by six LECM-certified concrete companies. Requiring LECM’s certification of concrete is taken into consideration for the entry requirements for the association.
The concrete with 100 year durability used in construction of Macau Light Rail Transit, are certified by LECM.
In 2012, LECM is commissioned by the Hong Kong-Zhuhai-Macau Bridge Authority, as a certifi cation body for certifying concrete used for the bridge. As of now, the concrete of the main construction including all batching plants used in Immersed Tunnel and Bridge structure have been certifi ed by LECM.
For the certified factory, LECM will conduct the quality management system audit , type test and conformity verifi cation in regular basis, in order to continuously evaluate the effectiveness of the implementation of quality management system and stability of quality of concrete product.
The onshore batching plants certified by LECM includes the local batching plants, batching stations in mainland used for Hong Kong-Zhuhai-Macau Bridge, batching stations for precast elements for Macau LRT project
Audit to offshore concrete batching ship, the quality management system audit is not only located on the ship, but also includes other supporting unit(or department) onshore.
