ORGANIZATION OF CONNECTION. GEO-TECHNICAL OBSERVATION AND MAINTENANCE OF UNDERGROUND WORKS
SECTION I. CONNECTION OF URBAN UNDERGROUND WORKS
Article 25. Technical connection
1. Technical connection means the connection between underground wirelines, cable lines, technical pipelines; technical trenches and tunnels.
2. Requirements on technical connection:
a/ To conform to approved urban planning or urban underground construction space planning;
b/ To conform to each work's use demand;
c/ To ensure synchronism;
d/ To ensure the technical requirements prescribed for each type of works.
Article 26. Spatial connection
1. Spatial connection means the creation of a space for connection between underground construction works and adjacent works, ensuring activities of people and machinery.
2. Requirements on spatial connection
a/ To conform to approved urban planning or urban underground construction space planning. In case the urban planning or urban underground construction space planning is not yet available, approval of the local planning management agencies is required;
b/ To ensure safety for people and works themselves and adjacent works;
c/To ensure convenience for use. exploitation and emergency exit when necessary.
Article 27. Connection agreement
Upon designing the construction of underground works, investors shall reach agreement with units managing the operation of urban technical infrastructure works or work owners or users for spatial connection (if any).
Article 28. Implementation of connection
Prior to work connection, investors shall notify connection plans and schedules to agencies and units agreeing with the connection for supervision and coordinated implementation.
SECTION 2. GEO-TECHNICAL OBSERVATION AND MAINTENANCE OF UNDERGROUND WORKS
Article 29. Geo-technical observation of underground works
1. Underground traffic works, public facilities, tunnels and key technical infrastructure works must be subject to geo-technical observation.
2. Requirements on geo-technical observation:
a/ Ggeo-technical observation shall be carried out according to regulations throughout the process of construction, exploitation and use of underground works:
b/ Geo-technical observation covers the observation of underground works themselves, the geological environment and adjacent works:
c/ Geo-technical observation shall be carried out strictly according to observation plans already approved by investors or use managers;
d/ When observing abnormalities, construction contractors shall notify them to investors or use managers and designing agencies for timely handling measures.
Article 30. Requirements on underground work maintenance
1. Underground construction works must be maintained under the law on construction.
2. Underground traffic works; underground public facilities; tunnels and key technical infrastructure works must be maintained according to regulations (regular and periodical maintenance).
3. Underground wirelines, pipelines and technical trenches must be periodically maintained.
4. Upon carrying out maintenance, attention must be paid to close examination of work connection systems; air-ventilation control, lighting, explosion- and fire-protection and environmental protection equipment (if any).
Article 31. Responsibilities of related agencies in the maintenance of underground works
1. Work owners or use managers shall:
a/ Organize the maintenance of underground works;
b/ Maintain underground works under the instructions and regulations of designing contractors, materials, technological equipment and work equipment supply contractors and observe relevant regulations and standards;
c/ Be held responsible before law for the quality of construction works if they are degenerated due to non-compliance with the prescribed work maintenance process;
d/ Periodically report on the maintenance and operation of underground works to local construction state management agencies.
2. Local construction state management agencies shall organize periodical and extraordinary inspections of work maintenance activities of owners or use managers of underground works.
