Precise Subsurface (PSSB) offers a range of project management and consulting services, focused on underground utilities mapping, survey and positioning.
Project management and consultancy services include:
Advance Underground Utilities Mapping
Electric, water and gas distribution utilities have asset geographically dispersed through the service territory in Malaysia. Knowing where the utility is, will help to make intelligent decision about planning and operation and improve the budget program in long term for the company. Because of information about utilities is have relationship with geographical factor, the need for comprehensive mapping method is crucial so than the user can make intelligent decision within the complete information. To avoid any disruption to an existing underground network utility, full information regarding the location of those utilities is essential before any excavation or installation / repair activities could be undertaken.
Geographical Information System (GIS)
PSSB provides fully comprehensive solutions for integrated GIS systems. Bringing GIS-experts from all disciplines and leading GIS-software know-how together in one organization. Having a clear focus of being the market leader in Malaysia, PSSB supports the IT-market with comprehensive WEB based GIS- as well as desktop-GIS-solutions. We can guarantee cost effective and straightforward solution adapted for each particular client. Out team of in-house and contract programmers will help clients to develop their own unique GIS database. We will also ensure that further development and enhancement of the GIS packages made possible as their need for a much more complex analysis surface. Spatial data comes from various sources such as existing maps, satellite imagery, aerial photography, certified plans and standard sheets etc.
Global Positioning System (GPS)
Our GPS Topcon Hyper GGD provides Graphics Module and direct link to GIS applications. Data can be process as Fast Static, Static, Rapid Static, Kinematic and Semi-kinematic. The module allows you to analyze and edit your final positions, lines and polygons before your export them, along with descriptive data, into standard GIS formats (ArcGIS, Map Info, Shapefile, DXF, etc.). ASC11 generic formats are also supported.
Photogrammetric Survey System
The company is comprised of people experienced in photographic equipment design, manufacturing, service and marketing. Photogrammetric surveys are used to help identify the general topography of the area of investigation before one engages the field survey units. It is also used now to gather the latest ground information for the compilation of GIS data. Photo mosaics produced help identify routes for new highways, transmission lines, gas pipe lines etc. This method can ensure that the designed route will not pass over residential areas, sites of sensitive nature such as cemeteries, schools and historical sites. Photogrammetry will only be cost effective if the area of coverage is very large.
Engineering Survey Services
We are usually appointed by Government and Semi Government bodies and Consultant Engineers to carry out engineering surveys to map out profiles and sections for the purpose of designing and planning route type projects such as roads, irrigation and flood protection schemes
Topography Survey Services
Topographical survey involves the generation of contours and the production of Digital Terrain Models. Such services are requiring by engineers and designers to help calculate volume for earthworks (cut and fill). With the advent of computer technology most of our clients want data in digital format, usually ASC11 and MOSS.
Hydrographic Survey Services
Hydrographic surveying can be loosely classified as offshore and land surveying. Surveys engaged helps engineers to identify the seabed / riverbed topography. Contours are also produce to enable them to quickly visualize the bed profile. For dredging purposes we will usually survey in front of dredger and feed the depth information online and will resurvey the path to ensure that the new depth is as required.
Oceanography Survey Services
Seabed sampling, salinity, wave modulation, currents and all data, which relates to the natural behavior of the inner space, can be classified as oceanography. These data must be gathered before one can decide on point of discharge of effluents; non-toxic wastes and also calculates the movements of sand banks and deposits at river mouths and in land ports.
Through strategic alliances we are also able to offer a wider range and depth of consulting expertise, for example in the geotechnical, engineering and environmental fields. PSSB project management services are applicable to a wide range of project sizes, from single operations to entire field developments.
