Foreword
Feature No. 11SE-A/ND12 is situated at Braemar Hill
Road, North Point.
LPM Division 2 of the Geotechnical Engineering Office
(GEO), Civil Engineering and Development Department
(CEDD) carried out / [Name of Consultant] was commissioned
by the Geotechnical Engineering Office (GEO), Civil
Engineering and Development Department (CEDD) under
Consultancy Agreement No. CE XX/YYYY (GE) to carry out*
a Stage 3(H) Study (Stage 3(H) Report No. S3(H)R xx/yyyy) for
the Natural Terrain Hazard Mitigation Measures.
This Maintenance Manual summarizes the LPMit works
carried out and the maintenance requirements of the NS/ND*
feature. This Manual also contains the results of the design
review during construction. Depending on the outcome of the
review, the design model finally adopted and therefore shown in
this report may be different from that in the corresponding Stage
3(H) Study Report.

Maintenance Manual No. MM XX/201Y
This maintenance manual consists of four parts:
PART 1
General Advice
1.1
The list geotechnical features (see Appendix I) and their locations (see Appendix II), at
Braemar Hill Road, North Point for which you have maintenance responsibility have been
constructed under the Landslip Prevention and Mitigation Programme (LPMitP) managed by the
Geotechnical Engineering Office (GEO), Civil Engineering and Development Department.
1.2
Maintenance requirements for natural terrain hazard mitigation measures, i.e. NS (i.e.
stabilization measures constructed on natural hillside to prevent failure) and ND (i.e. defense
measures to contain landslide or boulder fall from the natural terrain above) features are provided
in Geoguide 5 - Guide to Slope Maintenance (2003) published by the GEO.
1.3
Maintenance departments were informed by the GEO on 9 August 2013 that Routine
Maintenance Inspections (RMIs) are no longer necessary for soil-nailed hillsides completed
under the LPM or LPMit Programme, but inspection and maintenance of existing maintenance
staircases and drainage channels at soil-nailed hillsides will still be required.
1.4
Where maintenance departments are required to undertake tree risk assessment and/or
landscape maintenance in connection with the maintenance of natural terrain hazards mitigation
works, they should refer to the latest guidelines for Tree Risk Assessment issued by
Development Bureau and GEO Publication No. 1/2011 respectively.
1.5
Maintenance departments are urged not to replace vegetation on NS feature by chunam or
sprayed concrete as part of routine maintenance works. WBTC No. 25/93 includes guidelines on
the ‘Control of Visual Impact of Slopes’.
1.6
For the continued satisfactory performance of the NS/ND features, regular maintenance
including the upkeep of their physical integrity is essential, and the recommendations contained
in the relevant Circular/Geoguide/GEO Publication should be followed.
1.7
This manual provides information and specific advice for your future maintenance of the
NS/ND features. You should follow the specific recommendations on maintenance given in Part
2 of this Manual.
1.8
Parts 3 and 4 of this Manual provide you with the construction details and other relevant
information for your maintenance works.
5
Maintenance Manual No. MM XX/201Y
PART 2
Recommended Maintenance
2.1

Routine Maintenance Inspection to be carried out once every year/ xx years (Note 1);
(Others to be specified) (Note 2);
2.2
Routine Maintenance Inspection
Routine Maintenance Inspections should preferably be carried out between October and
February, and any required maintenance works should be completed before the onset of the wet
season in April. These maintenance inspections should be undertaken by your Assistant Clerk of
Works, Technical Officer, Works Supervisor or above, as appropriate, who should make
recommendations with regard to the following maintenance items (such inspecting officers are
expected to have the knowledge of and experience in recommending the list of maintenance
items):
1

clearance of accumulated debris from drainage channels, catch trenches and pits,
containment basins and straining structures;

removal of accumulated debris behind the debris/rockfall resisting barriers(Note 3);

repair of or replacement of damaged/corroded components of the debris/rockfall
resisting barriers;

repair of cracked or damaged drainage channels or maintenance access;

repair of or replacement of rusted steel furniture;

removal of any vegetation that has caused severe cracking of drainage channels or
hard surface;

unblocking weep-holes and drainage outlet;

repair of or reinstatement of the ground adjoining the measures if affected by
severe erosion;
Refer to paragraph 1.3 of this Manual and Sections 7.3 and 7.4 of Geoguide 5 (3 rd Edition)
2
Engineer inspections for Maintenance are not normally required unless specified by the designer or in special
provisions. Geoguide 5 (3rd Edition) Section 7.5 refers.
3
For flexible barriers, an immediate maintenance inspection should be carried out after the occurrence of
landslide. Arrangement should be made to clear the landslide debris as quickly as possible in order to avoid
potential instability due to prolonged period/accumulation of surcharge, and to ensure the continuing functioning of
the flexible barriers.
6
Maintenance Manual No. MM XX/201Y

repair of or reinstatement of the pavement of the vehicular maintenance access;

repair of/notification to relevant parties of leaky exposed water-carrying service;
(others to be specified to upkeep the integrity and function of the measures, e.g.
specific maintenance requirement from the supplier of any defense measures).
Records of the geotechnical features (see Appendix III) and records of routine
maintenance inspections and works (see Appendix IV) should be properly made and kept.
In cases where unusual conditions or problems are observed during routine maintenance
inspections or immediate maintenance inspections, e.g. a check dam filled up with a large
amount of landslide debris or significant movement observed at boulders supported by buttresses,
the owner or the party required to maintain the mitigation measures should seek advice from a
professionally-qualified geotechnical engineer and inform the Landslip Investigation Section of
LPM Division 1 of GEO.
2.3
Other Specific Maintenance Requirements for the Geotechnical Features
Details shall refer to Appendix XI.
