B DETAILED SUBSURFACE DETECTION, INVESTIGATION AND MAPPING OF
UNDERGROUND UTILITY NETWORKS FOR JKR CONTRACTORS
1. SCOPE OF WORKS
The scope of work calls for the supply of all labour and use of machineries,
equipment and materials required for the complete sub-surface detection,
investigation and mapping of underground utilities for the above project including
the following;
a) Detection of underground utilities at Quality Level B based on PKPUP Bil. 1
Tahun 2006
b) Construction of survey reference grid with total Station or GNSS;
c) Surface reference line survey;
d) Complete underground utilities detection including markings of power and
telecommunication cables, sewer, water and gas pipes.
1.1. The Licensed Land Surveyors (LSr) use GNSS or total station to construct a
survey control point network, “grid”, in which the position of all survey works
and detected services will relate.
1.2. All survey results will be in State’s GDM Cassini-Soldner coordinate system
/ latest state coordinate system (i.e. GDM2000).
1.3. Base map survey, “cover layer” is carried out surveying positions of
pavement edges, kerb lines and / or road edges, traffic dividers and valve /
manhole cover. All topographic details need to be shown in grey on the plan.
1.4. All existing utilities shall be detected /surveyed under the specified area.
1.5. The conductive services such as cables & pipes is to be located, pin pointed
and traced using electromagnetic cable and pipe detection instruments
(electromagnetic locator – EML) and these positions are recorded in x, y & z
co-ordinates on to a field data logger before transferring to the computerized
utility information database.
1.6. Non-metallic services to be detected using Ground Penetrating Radar (GPR)
whenever soil conditions allow.
1.7. Relating attribute data to the service, i.e. materials, diameters, type, ways
and voltages to be logged and retained wherever and whenever possible.
(3)
1.8. The LSr is to provide digital maps to the client, containing information on all
underground services within the project area. The LSr will also provide site
instruction inclusive of initial remarking on site to the client at the
commencement of excavation works under the project area.
1.9. The LSr is to maintain an estimated accuracy level of +/- 10 cm horizontally
and +/- 10 % from the actual depth vertically of all buried services located up
to three (3) meters deep.
1.10. Wherever possible, the works are to be carried out during the daytime.
However, due to traffic conditions, the detection and survey works, where
necessary can be conducted at night between 9.00 p.m. to 6.00 a.m.
1.11. The LSr using available electromagnetic techniques and equipment (such as
electromagnetic locator (EML) / pipe & cable locator (PCL) and Ground
Penetrating Radar (GPR) at its disposal is to locate all buried PVC, asbestos,
concrete and other non-metallic service. The LSr will undertake to advise the
client of any problems it experiences or potential hazards it anticipates.
1.12. As a general practice, the LSr will be liable to any damages to underground
utilities due to the negligence of its staff. In this respect, the LSr is to detect
and locate all metallic and accessible non-metallic services;
1.12.1. Electromagnetic locator (EML) / pipe & cable locator (PCL) can be
used to detect metallic / conductive services such as iron and steel
pipes for water, gas, sewer, oil, electric cables, copper
telecommunication and control cables.
1.12.2. Ground Penetrating Radar (GPR) can be used to detect non-
metallic services such as sewer, water and drain pipes, accessible
ducts (i.e. empty protection pipes for optic fiber and other cables)
and other accessible non-conductive underground objects.
2. SUBMISSION OF SURVEY PLANS, UTILITIES, MAPPING, DIGITAL DATA

4. ATTRIBUTES
The LSr shall follow the Malaysian Standard Geographic Information / Geomatics
Features and Attribute Codes (MS 1759:2015). This Malaysian Standard
specifies the method for encoding of geospatial data and provides the description
of features and their associated attributes for the exchange of digital
geographic information.
4.1. Quality Level Attributes
4.1.1. General
The quality level attribute of an underground utility feature is the most
important information aside from its alignment or presence in a utility map.
As such due care should be given to precisely indicate the quality level of
an underground feature especially in hardcopy maps given the fact that in
any congested corridor, the horizontal and vertical separation between
utility features could be reduced to several decimeters, and at plotting
scale such separation may be difficult to discern. Careful usage of the
following cartographic elements can help in ensuring a reliable indication
of the quality level of underground features.
4.1.2. Labelling
This is also one of the methods of differentiating between the quality
levels, utility type, ownership, date of depiction, accuracy of surveyed
appurtenances, end points of any utility data, active, abandoned, or out-
of-service status, size, condition, number of jointly buried cables and
encasement.
4.1.3. Symbol Embedding
Symbol embedding can also be used to indicate the different quality levels
of underground utility data.
4.1.4. Colour
Colour is frequently used to indicate type which can be used in conjunction
with other methods. (Please refer Pekeliling Ketua Pengarah Ukur dan
Pemetaan Bilangan 1 Tahun 2016 (PKPUP Bil 1/2016) – Garis Panduan
Kod Warna dan Penandaan Utiliti Bawah Tanah and refer attachment
Appendix C).
(8)
4.1.5. Line Weight
Line weight can be used at actual scale to depict the size of the utility.
However, it has the effect of obscuring other data if the line size is large.
4.1.6. Layer
Occasionally layers are used to portray various attributes. For example,
quality level ‘A’ data could be on one layer, quality level ‘B’ data on
another, and etc. All layers must be turned be on to present the complete
utility information particularly in a geographic information system (GIS).
4.1.7. Annotation
Annotation should be used with care as to ensure that it does not obscure
other utility data.
4.2. Utility Depiction Legend
In most cases, an underground utility map should be provided with a
separate utility legend to clearly indicate the methods of quality level
differentiation and other utility attributes.
4.3. Parcel Boundaries
Parcel boundaries shown shall be derived from the National Digital
Cadastral Database (NDCDB) currently maintained by JUPEM.
4.4. Lot Numbers
Lot numbers of all parcels as depicted in the NDCDB shall be shown
whenever possible.
4.5. Names of Building, Street, Road and River
Official names of buildings as well as names of streets, roads and rivers
shall be shown. All features and SI of m or mm units must clearly state on
the map.
4.6. North Arrow
An arrow-like symbol indicating the direction of the grid north and the true
north shall be shown.
(9)
4.7. Scale Representation
Since maps must necessarily be smaller than the areas mapped, their use
requires that the ratio or proportion between comparable measurements
be expressed on the map. This is called map scale and should be the first
thing which the map user becomes aware. Scale should be expressed as
a statement of map distance in relation to earth distance or a graphic (or
bar) scale or both.
4.8. Map Date
The publication date the map should be prominently displayed.
4.9. Map Coordinate
Again, map coordinate is most important. Do clearly state the coordinate
system and the value of x, y & z on the map as truly pick up and using at
the site.
4.10. Marginal Information
Marginal information may include such items as section, town, city and
state names, scale, north arrow, legend, published date, disclaimer and
map index, among others.
4.11. Disclaimer
Disclaimers are used to limit and define the map author’s responsibility for
the content, accuracy and currency of the map. Although some maps may
require specialized disclaimers, the following disclaimer represents one
suggestion:
“Not to be treated as a map depicting property boundaries”
5. METADATA
Metadata are commonly defined as the data about data or the data about the
processes performed on the data. The major uses of the metadata are;
a. To maintain an organization’s internal investment in geospatial data;
b. To provide information about an organization’s data holdings to data
catalogues, clearing houses and brokerages; and
(10)
c. To provide information needed to process and interpret data to be
received through a transfer from an external source.
Thus, in order to facilitate their use, underground utility maps produced shall
be accompanied with appropriate metadata which complies with Malaysian
Standard Geographic Information / Geomatics Features and Attribute
Codes (MS 1759:2015).
