Services

To locate and identify all underground utilities, including power and telephone cables, gas, water, drainage and waste pipes, by Non-destructive method and provide utility mapping with the depth and position of these utilities.

To provide utility specialist services for Utility Surveying for location, depth and condition. We will carry out the 8 steps designed by EMSD (Record plan collection, passive detection, trial pit supervision, active detection, ground marking, photo taking, written report preparation and site briefing).

To get information about changing ground characteristics with depth.by sending a radio signal or series of signal into the ground and then receives the reflected signal. It can detect the void and non-metallic object in underground.

To obtain coordinates of the land features and the relevant natural and artificial features for the creation of a topographic map by using land surveying equipment, such as Total Stations, Surveying Tripods and Prisms.

To inspect the internal conditions of pipeline with a camera which installed on a wheel tractor and can travel along various type and size of pipeline, the internal condition can be record in from of video and photo.

To Investigate manholes and to provide detailed information on the features and defects of the manholes for the design and construction of drainage works and data are recorded in a standardized Manhole Card.

To inspect and test of Buried Water Carrying Services in Slope and Hillsides - Checking Typical Slope Condition. To inspect the potential risk on the slope which affect the stability and the structure of slope and therefore to prevent landslip.

To carry out both root inspection and trunk inspection and offer advanced non-invasive subsurface information as to the location, depth and density of tree roots, and further specialist investigations on tree decay.

To assess the condition of the pipes buried underground by different surveys and techniques such as Conduit Condition Evaluation (CCTV and ME Survey), Coating Defects Survey and Water Leakage Detection depends on the situation.

To locate voids and inspect ground structure and analyze road structure and void location by expert interpretation.

To carry out flaw detection, concrete cover and reinforcing bar (rebar) size measurement, in-situ concrete strength test, corrosion monitoring to ensure the safety and stability of an aged building.

To measure the flow velocity and flow depth to calculate the flow rate by using flowmeters.

To monitor, control, locate, localize and pin-point any suspected leaks from any pressurized water supply system.

To arrange the data in an organized manner and establish a centralized database that gathers data from all utility undertakers and companies allows easy search and retrieval, so that utility information can be obtained more easily.

To build a systematic utility system to make the installation of new utilities, maintenance of existing utilities and repair of deteriorated utilities easier.

To repair the underground pipeline by trenchless method without excavation including cured-in-place-pipe (CIPP) lining, sliplining, close-fit-pipe lining and modified sliplining.

To plan, organize, motivate and control resources in utility projects systematically to make sure the survey procedure and progress in the right trick.

To build up a 3D model which is a digital representation of physical and functional characteristics of infrastructure.

To manage large amount of underground utilities information as well as to facilitate the effectiveness of management, data input and report generating.

To provide education and training to enhance the related knowledge and skills of utility practitioners. Our trainings include safety, CCTV, Utility Survey, Manhole Survey, Water Leakage Detection and etc.

To build up a standard in utility industry to ensure the quality of work. Our publications for standard setting include "HKCCEC", Guideline, Method Statement, Pamphlet, Particular Specification and Work Procedure for different surveys.
