WHAT WE DO
Our Service Scope
1Call mainly provides services of location survey, condition survey and management in the utility industry. 1Call commits to provide safe and high quality utility related services. The followings are some details of our scope of services.
Surveying & Mapping
A) Comprehensive Utility Survey (Pipe Cable Locator Survey, PCL) 綜合管綫測量
To locate and identify all underground utilities, including power and telephone cables, gas, water, drainage and waste pipes, by non-destructive methods and provide utility mapping with the depth and position of these utilities.
B) CP Services
認可合資格人士服務
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)
C) GPR(Ground Penetrating Radar) Survey for utilities
管綫雷達探測
To get information about changing ground characteristics with dept. 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.
D) Topographical Survey 地形檢測
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.
Condition Assessment
E) Conduit Condition Evaluation 管道狀況評價
To inspect the internal conditions of a pipeline, a camera that is installed on a wheeled tractor can travel along various types and sizes of pipelines, the internal conditions can be recorded in the form of video and photos.
F) Manhole Internal Condition Survey 沙井狀況評價
To investigate manholes and to provide detailed information on the features and defects of the manholes for the design and construction of drainage works, data are recorded in a standardised Manhole Card.
G) Advanced Leakage Detection of Buried Water Carrying Services Affecting Slopes 斜坡管道測漏
To inspect and test Buried Water Carrying Services in Slope and Hillsides - checking typical slope conditions. To inspect the potential risks on the slope which affect the stability and structure of the slope and therefore to prevent landslip.
H) Flow Study in Drainage Conduit 流量監控
To measure the flow velocity and flow depth to calculate the flow rate by using flowmeters.
I) Water Leakage Detection and Management 漏水監控及管理
To monitor, control, locate, localize and pinpoint any suspected leaks in any pressurized water supply system.
Trenchless & Rehabilitation
J) Pipe Rehabilitation by Trenchless Technology 管綫維修(開挖工程技術喉管修補)
To repair the underground pipeline by trenchless methods without excavation, including cured-in-place pipe (CIPP) lining, sliplining, close-fit pipe lining and modified sliplining.
K) Project Management for Utility Industries 管綫項目管理
To plan, organize, motivate and control resources in utility projects systematically to make sure the survey procedure and progress in the right trick.
Trenchless & Rehabilitation
Data & Management
L) Data Management for Utility Records 管綫資料管理
To arrange the data in an organized manner and establish a centralized database that gathers data from all utility undertakers and companies so as to allow easy search and retrieval, finally utility information can be obtained more easily.
M) Utility Management 管綫管理
To build a systematic utility system to make the installation of new utilities, maintenance of existing utilities, and repair of deteriorated utilities easier.
N) Building Information Modeling for Infrastructure 建築資訊模型(基建)
To build up a 3D model, which is a digital representation of physical and functional characteristics of utilities and infrastructure.
O) Integrated Data Management System (IDMS) 綜合資料管理系統
To manage large amount of underground utilities information as well as to facilitate the effectiveness of management, data input and report generating.
