3 Basic Requirements
3.0.1 The construction organization shall have corresponding construction qualification for road works in city and town.
3.0.2 The construction organization shall establish sound construction technology, quality and safe production management system as well as formulate and implement construction management systems.
3.0.3 Before construction, the construction organization shall organize relevant construction technology management personnel to carry out deep site investigation, learn about the site condition and make sufficient construction preparation.
3.0.4 Before commencement, the construction organization shall investigate the construction site according to the contract documents, design documents, relevant laws and regulations, standards, codes and specifications as well as information on such structures as underground pipelines within the construction boundary and engineering hydrogeological information; moreover, the construction organization shall prepare construction organization design according to the engineering characteristics and make examination and approval according to its management procedure.
3.0.5 The construction organization shall be carry out according to the approved valid design documents as specified in contract. The construction organization mustn't carry out according to unapproved design change and engineering negotiation.
3.0.6 During construction, the construction measurement shall be rechecked to guarantee accuracy.
3.0.7 During construction, a safe technical disclosure system must be established. In addition, relevant safety technology education and training shall be provided for operation personnel. Before operation, the personnel in charge of construction technology must make detailed safe technical disclosure to the operation personnel.
3.0.8 In winter and rainy season, a special construction plan shall be formulated based on actual engineering conditions and implemented upon approval according to the examination and approval procedure.
3.0.9 During construction, the next subitem engineering mustn't be proceeded before the previous subitem engineering passes the acceptance.
