Stream UP is the innovative lightweight, multifrequency and multichannel GPR dedicated to utility mapping on extensive areas. Operate even at high speeds.

Supporting Singapore’s urban development with Stream UP for underground truth.

Non-invasive GPR technology for Underground Mapping of extensive areas.

Stream UP

Singapore is a metropolitan city state home to more than 5 million people. She has been characterised by a restricted availability of land and intense population density, which obliges the construction industry to pioneer urban development projects that make the most effective use of underground spaces, while simultaneously supporting existing buried infrastructure and the laying of new utilities.

To use underground space, one must first understand where space is underground. A complete knowledge of subsurface infrastructures is required to always ensure accurate and reliable planning of works, to speed up project schedules, and to increase safety of workers as well as the general public during all construction phases. HSC Pipeline Engineering Pte Ltd - with its 30 years of experience in building underground utilities, plus a strong culture of integrating new relevant technologies and methods into its service offerings - plays the role of a key partner in pipeline projects and surveying conducted for utility organisations across the city of Singapore. 

Stream UP, an easy way to capture underground utilities on extensive areas.

HSC operates IDS GeoRaradar’s Stream UP; a multichannel, multi-frequency, double-polarized, lightweight GPR system that can be installed on the back of any standard vehicle to accurately detect and map underground utilities on the move.

Stream UP is the right solution to efficiently operate in extended urban environments. Just as another vehicle on the road, HSC’s GPR vehicle does not slow down traffic in the big city of Singapore while it also collects the necessary data for utility projects to be planned and executed. Stream UP can operate at a speed of up to 150 km/h (93 mph), with a suggested operating velocity of 60 km/h (37 mph) for a perfect balance of safety, data quality and work efficiency.
The Stream UP solution is lightweight and easy to setup; this innovative GPR system can be mounted directly
on site, needing only two people for transportation and assembly and just one operator to control it. Stream UP, operates in complete absence of contact with the ground and so dramatically reduces the stress on the physical system, consequently reducing its maintenance overheads.

Stream UP employs Hexagon’s latest software technology solutions for manifesting actionable information: uMap on-field software and IQMaps post-processing software for fast interfacing between users and GPR data.

Providing accurate detection of underground utilities with Stream UP GPR system.

Utility owners’ asset drawings often fail to provide reliable data on the exact location of utilities; even surveyed coordinates sometimes happen to be inaccurate, due to the accumulation of systemic error over time, or just “guessing” on where pipes are after trenches have been backfilled. By using GPR systems such as IDS Stream UP, a quick scan of vast areas for underground utilities becomes possible and having a complete and reliable 3D overview of where things are buried becomes a reality. GPR systems are a key component of success in the accurate localization of underground utilities, enabling
optimised planning and safer excavations and installations.

Since its first introduction,
Stream UP has revolutionised the way surveyors conduct utility analysis, minimising excavation disruptions, saving costs and time while dramatically increasing productivity. For their efforts to improve how work is done, HSC has been awarded many accolades at various levels, including the Techblazer Award 2023 for Best Adoption (SME).

HSC Pipeline Engineering Pte Ltd found in Stream UP the perfect underground mapping solution providing with a fast and full scan of the intended work area and the clearest view on underground infrastructures.

Stream UP represents the easiest way to capture underground utility assets on extensive areas, facilitating the whole process - before, during and after data acquisition - while boosting overall productivity. If we compare Stream UP’s performance to the standard trench survey approach, that checks for underground structures approximately every 30 meters and permits vision of only 3.3% of the entire operations theatre, it is possible to understand the great value Stream UP can add to underground surveys by covering 100% of the intended survey area with no excavating.

With Stream UP, HSC can rely on a non-invasive inspection of underground utilities to provide an
accurate and reliable map of underground utilities up to 2.5m-3m depth.

Utility strikes have become more commonplace over the world, with severe accidents on the rise that cause civil and business losses in the millions. Stream UP drastically reduces the risk of hitting underground infrastructure while digging by leveraging its non-destructive testing nature. In-fact, as it provides ground truth, Stream UP enables work teams with awareness on where not to dig when utilities need to be laid.

This system enabled HSC to drastically reduce the number of trench surveys required for each surveying project with an important decrease in costs. The use of Stream UP for the analysis of underground infrastructure has led to savings of more than 90% per lane/km, and more importantly, it enabled HSC to adopt a more sustainable workflow with less disruption to the public – it’s the win-win philosophy of “measure twice, dig once”.

Digging trenches will always be time-consuming and costly. Stream UP allows for a comprehensive detection and mapping of the underground utilities, bypassing the need for invasive methods such as vacuum digging. Its non-invasive GPR technology is able to provide highly reliable data (80%-90%) in a fast and productive way, fulfilling the need for good quality information without the traditional encumbrances of dig-to-find.
