  • The Landslip Preventive Measures Division 3 consists of a Works (W) Section and three Consultant Management (CM) Sections.
  • The Works Section prepares tender documents, calls tenders, analyses tenders and supervises in-house landslip prevention and mitigation works that are mainly designed by GEO's Landslip Preventive Measures Division 2. This Section is also responsible for maintaining and updating a library of sample tender documents for landslip prevention and mitigation works contracts which serves as reference material for both in-house and consultants’ project staff.

  • The Works Section also carries out ongoing second-party audits on works in consultants-administered contracts. Experienced inspectorate staff carry out regular audits on soil nail installation and grouting works. This ensures that our soil nailing works are carried out to a uniform and consistent standard amongst all consultant and in-house administered contracts.
  • As part of the measures used to accelerate the LPM programme, we have since 1995, employed consultants to carry out geotechnical studies, design of preventive works, preparation of contract documents and supervision of construction. These consultants are managed by the CM Sections. The duties of CM Sections include reviewing and monitoring of works progress and programming for all associated assignments to their consultants in relation to upgrading slopes/retaining walls, expenditure control and coordination with other Government Departments.
