All regulatory authorities for relevant sectors involved in public construction shall keep the competent authority informed of the planning and site selection for any major public construction projects under their jurisdiction.
The definition of “major public construction projects” in the preceding paragraph shall be as determined by the central competent authority in collaboration with the Public Construction Commission and the Council for Economic Planning and Development, Executive Yuan.

Should a site of land development activity fall in whole or in part within a geologically sensitive area, it shall first undergo a geological site investigation and geological safety assessment before an application for land development is filed. But this requirement does not apply to emergency disaster relief plans.
For development activity for land that is not in areas referred to in the preceding paragraph, a geological investigation shall be conducted in accordance with applicable laws and regulations.

For geological site investigations and geological safety assessments under paragraph 1 of the preceding Article, one of the following methods shall be adopted, according to the circumstances:
1. Examine existing available data, and perform the geological safety assessment on that basis.
2. Carry out an on-site investigation, and perform the geological safety assessment on that basis.
Regulations setting out matters for compliance in connection with the methodology determinations, survey or assessment items, content, and procedures of site geological investigations and geological safety assessments under the preceding paragraph will be prescribed by the central competent authority in consultation with the relevant regulatory authorities.

Geological Site investigations and geological safety assessments conducted under paragraph 1 of Article 8 shall be performed and attested by duly registered and practicing professional applied geological engineers, professional geotechnical engineers, professional civil engineers, professional mining engineers, professional hydraulic engineers, professional soil and water conservation engineers, or professional engineers permitted under the provisions of the Professional Engineers Act to practice geology.
When a geological site investigation or geological safety assessment is to be conducted independently by a regulatory authority for a relevant sector, by a public enterprise, or by a public legal person, it may be conducted by a person within that agency, enterprise, or legal person who has duly obtained certification as a professional engineer in the corresponding discipline.

Those required to conduct geological site investigations and geological safety assessments under paragraph 1 of Article 8 shall include the survey and assessment findings in any documents and figures required to be submitted for review under applicable laws and regulations.
Reviewing agencies shall invite geologists, or practicing professional engineers as specified in paragraph 1 of the preceding Article, to participate in reviews, or entrust professional bodies to perform the reviews. However, agencies capable of performing reviews themselves are not constrained by this requirement.

In order to monitor and study the occurrence of geological hazards, competent authorities may install geologic monitoring facility.

For those land development activities which geological site investigations and geological safety assessments are required to be conducted under paragraph 1 of Article 8, the developers, operators, users, or owners of the land shall take preventive measures to guard against the occurrence of any geological hazards during the construction or usage stage.

The competent authority or the regulatory authorities for relevant sectors may entrust professional engineers or related agencies (or institutions) to survey and appraise geological hazards.
The central competent authority shall determine the qualifications and conditions of persons or bodies entrusted under the preceding paragraph, and the methods used in the surveys and appraisals.

The competent authority may send inspectors to enter land, whether public or private, to carry out necessary geological surveys, installation of geological monitoring equipments, or geological hazard appraisals.
The competent authority, in response to an occurred or perceived geological hazard on land that could threaten a public safety hazard, may send inspectors to enter onto the land, whether public or private, to carry out a geological survey or hazard appraisal. The landowners, users, or operators may not refuse, evade, or obstruct such entry, survey, or appraisal. In the case of entry onto land used for national defense facilities, however, consent must be solicited from the competent authority for the land used for the national defense facility.
