【 SURVEY 】 Dimensional Control Survey
12 03 - 20
This is a type of survey conducted in or on a non-level surface. Common in the oil and gas industry to replace old or damaged pipes on a like-for-like basis, the advantage of dimensional control survey is that the instrument used to conduct the survey does not need to be level. This is useful in the off-shore industry, as not all platforms are fixed and are thus subject to movement.Read more on https://en.wikipedia.org/wiki/Surveying
【 SURVEY 】 Hydrographical Survey
11 03 - 20
Hydrographical survey involves the measurement and description of features of the seabed / riverbed, swamps, ponds, dredging site, foreshore structure and the 2.515 HWM line. Registered Surveyor carries out such survey at coastal areas whereas hydrographic surveyor conducts their survey in deep seas for maritime and navigational purposes.Hydrographic survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil ...
【 SURVEY 】 Measured Survey
11 03 - 20
To survey buildings under conservation, their facades using 3D scanning technology or the conventional 3D point survey and to produce elevations, cross sections and floor layouts of the buildings, such a survey may be conducted before renovation works, for commercial purpose, or at end of the construction process.
【 SURVEY 】 Monitoring Survey
11 03 - 20
Deformation monitoring is to measure the position of structures or their surrounding features at regular time interval for position changes. This data is useful for the purpose of deformation analysis, predictive maintenance and triggering of alarming system. Temporary stop-work or corrective works can be applied in time to prevent serious incidents from happening.Deformation monitoring (also referred to as deformation survey) is the systematic measurement and tracking of the alteration in t...
【 SURVEY 】 Tunnel Survey
11 03 - 20
Tunnel survey involves in measuring the locations and layout of tunnel’s position and guiding of tunnel boring machine in the correct direction and position. Survey activities include ground surface survey, transferring the alignment and levels underground, measuring tunnel position and providing boring line.
【 SURVEY,GIS 】 Road Data Hub/GIS Data Hub
11 03 - 20
Road Data Hub/Road GIS Data HubThis survey involves the recording of existing physical information along the road for inventory purpose. The survey measures road infrastructures consisting of road tarmac, link ways, dividers, bridges, drains, bus bays, railings, manholes, traffic junctions, signs & terminals, parking space, trees, and encroachment issues.
【 SURVEY 】 As-built Survey
11 03 - 20
As-built survey is usually required after the construction is completed for purpose of comparing it with the design drawings. As-built survey plan is submitted to relevant authorities. As-built survey documents the location of recently constructed elements of a construction project. As-built surveys are done for record, completion evaluation and payment purposes. An as-built survey is also known as a 'works as executed survey'. As built surveys are often presented in red or redline and laid o...
【 SURVEY 】 Engineering Survey
11 03 - 20
Engineering survey is a service usually rendered to construction companies for the construction of buildings, roads, tunnels, drainage & sewerage lines, parks, land reclamation, airports and wharves.Engineering surveying: topographic, layout, and as-built surveys associated with engineering design, Often need geodetic computations beyond normal civil engineering practice.
【 SURVEY 】 Cadastral Survey
11 03 - 20
Cadastral survey (or previously known as title survey) refers to survey of land and strata lots for the purposes of registration of land-ownership, issues of land titles and other land-related matters. It involves the demarcation of property boundaries and determination of areas and is regulated under the provisions of the Boundaries & Survey Maps Act. One of the primary roles of the land surveyor is to determine the boundary of real property on the ground. That boundary has already been est...
【 SURVEY 】 Topographic Survey
10 03 - 20
Topographical helps determine accurately the terrestrial or three-dimensional space position of points and the distances and angles between them using leveling instruments such as theodolites, dumpy levels and clinometers.Topographic surveying is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief but also natural and artificial features, and even local history and culture.Topographic surveying is the mapping of existing natura...
