Frequently Asked Questions
What is an underground utility survey?
An underground utility survey is a systematic investigation of buried infrastructure — pipes, cables, ducts, and other services — beneath a site. RIIM uses a combination of Ground Penetrating Radar (GPR), electromagnetic pipe locating (EPL), and physical verification to detect, map, and classify underground utilities to PAS-128 or ASCE 38-22 standard.
Why is an underground utility survey required before excavation in Bahrain?
Utility strikes during excavation are a leading cause of construction fatalities, project delays, and cost overruns in Bahrain and the GCC. An underground utility survey identifies buried services before excavation begins, allowing contractors to plan safe dig routes and avoid utility conflicts. Many Bahrain government and BAPCO projects now require a PAS-128 compliant utility survey as a condition of permit to excavate.
What is the difference between PAS-128 and ASCE 38-22 for utility surveys?
PAS-128 is the British Standard for underground utility detection and mapping, widely used in Bahrain and the GCC. ASCE 38-22 is the American Society of Civil Engineers standard, commonly specified on Saudi Arabia and NEOM projects. Both define quality levels for utility data accuracy. RIIM is compliant with both standards and can deliver to either specification depending on project requirements.
How long does an underground utility survey take in Bahrain?
Survey duration depends on site area and complexity. A typical urban site in Manama of 1,000 to 5,000 square metres takes 1 to 3 days for fieldwork, with processed deliverables available within 3 to 5 working days. RIIM can provide preliminary on-site findings for urgent excavation decisions.
What does RIIM deliver after an underground utility survey?
RIIM delivers a PAS-128 or ASCE 38-22 survey report, georeferenced utility drawings in AutoCAD DWG and PDF format, a utility schedule with depth and confidence level for each detected service, and a digital data file. GIS shapefiles, BIM models, and 3D utility models are available as additional deliverables.
