National Buried Infrastructure Facility
University of BirminghamBirmingham
The National Buried Infrastructure Facility at the University of Birmingham supports experimental research on buried infrastructure and ground interaction, including physical and operational performance at or near full scale. Current pages describe a 25 m by 10 m by 5 m deep pit, a moveable floor, pipe loops, material characterisation and sensing equipment. Use nbif@contacts.bham.ac.uk to discuss a proposed experiment. UKCRIC describes collaborative research access and states that it is not a lab service provider or accredited analysis service.

Key facts
- University research facility
- The current University of Birmingham and UKCRIC pages identify NBIF as a facility for research, innovation, education and training in buried infrastructure and ground interaction.
- Research at or near full scale
- The facility record describes experiments on pipelines, cables, culverts, tunnels, road foundations and barrier-wall systems to study physical and operational performance.
- Dedicated enquiry route
- The university publishes nbif@contacts.bham.ac.uk for NBIF enquiries and potential collaboration. Discuss experiment requirements and resources before arranging access.
- Collaborative access
- The NBIF record lists industry partners and other researchers, proof-of-concept work, fellowships, secondments and PhD studentships. UKCRIC gives EPSRC-funded proposals top priority for facility and equipment use.
Testing capabilities
Buried infrastructure and ground-interaction experiments
NBIF supports at or near full-scale physical and operational performance research on buried systems. Its pit, loading frame, strong wall and moveable floor support experiments involving surface or horizontal loading and ground movements such as tunnelling effects or heave. Confirm the proposed system and configuration directly.
Soil and material characterisation
The equipment page describes traditional and dynamic triaxial systems, shear boxes and automatic oedometers for soil behaviour research. Published dynamic-triaxial conditions include 38 mm, 50 mm and 100 mm diameter samples with loading up to 5 Hz. These are specific instrument conditions and require a suitable agreed test procedure.
Pipe-loop experiments
The facility has separate external and internal pipe-loop arrangements. The external buried MDPE loop supports water flow and access around the pipe, while an internal network can be constructed in the pit. Their published pressures differ, so confirm the required loop, water-flow arrangement and experiment directly.
Buried-target mapping and structural monitoring research
NBIF lists IDS Duo and IDS Stream C ground-penetrating-radar instruments for mapping buried targets and LUNA OBR and ODiSI optical-fibre systems for strain or temperature monitoring on structures. Detection depth, resolution and monitoring performance depend on the selected equipment and experimental conditions.
Equipment and published limits
| Specification | Published value | Conditions |
|---|---|---|
| Main research pit | 25 m by 10 m by 5 m deep | The centre section has a moveable floor. The pit can be subdivided using blocks and includes a surface-loading frame and a strong wall. Dimensions are facility geometry, not a guaranteed specimen envelope. |
| Moveable floor | 10 m by 5 m section, 50 actuators, 300 mm maximum travel per actuator | UKCRIC publishes the section dimensions. The university describes 150 mm travel in either direction per actuator for ground-movement simulation. Confirm the required displacement pattern and usable setup. |
| Published loading actuators | 200 tonne, 50 tonne and 10 tonne static, plus four 25 tonne static or dynamic actuators up to 10 Hz | These are the separate ratings published for loading the ground or structures. They are not a combined simultaneous-load rating or a guaranteed force envelope for every setup. |
| Separate pipe-loop conditions | External approximately 70 m, 100 mm MDPE, approximately 1 m burial, up to 8 bar. Internal maximum 6 bar. | The external loop has three access chambers. The internal network can be constructed in the pit. Approximate dimensions and the two different pressure limits remain tied to their respective loops. |
Access and contact
Email nbif@contacts.bham.ac.uk for NBIF enquiries and potential collaboration. Explain the proposed experiment, infrastructure or material, scale, loading or flow conditions and required measurements. UKCRIC asks users to begin discussions early so project resources and intellectual-property arrangements can be planned, with EPSRC-funded proposals given priority. Confirm the access route and agreed research arrangements directly.

Standards and accreditation
- Research-access and accreditation boundary
- UKCRIC expressly states that it is not a lab service provider or accredited analysis service. The bounded NBIF pages describe research capabilities and equipment but do not establish a method-specific accredited testing scope. Confirm any required standard, procedure or independently verified accreditation directly.
What to confirm with the facility
- Published pit dimensions, actuator ratings, stroke and loop pressures apply to the named facilities and configurations. They do not guarantee that a proposed specimen, combined loading arrangement or pressure campaign is suitable.
- NBIF access is described through collaborative research opportunities. UKCRIC’s statement about not providing lab or accredited analysis services remains explicit, and its project priorities do not guarantee availability for a particular date.
- Confirm experiment design, material preparation, installation and removal, instrumentation, safety responsibilities, programme, costs and reporting requirements directly.

Sources and review
Reviewed by Arc on 1 October 2026 using fresh University of Birmingham NBIF overview, equipment and research-capability pages and fresh UKCRIC facility and access pages. The overview links current facility reports and a dedicated enquiry route, while the equipment body describes the experimental installations. No NBIF publication or modification date was verified. Unrelated NewsArticle metadata on the equipment page, copyright dates and the historical October 2021 showcase are not facility-page dates. Collaborative research access remains distinct from an accredited analysis service.

National Buried Infrastructure Facility (NBIF) - University of Birmingham
The operator page identifies NBIF as a research facility and publishes nbif@contacts.bham.ac.uk for facility and collaboration enquiries. The generic university footer address and telephone are not presented as an NBIF-specific street address or contact.
NBIF Equipment - University of Birmingham
The body describes the NBIF test hall, pit, floor actuators, pipe loops, material characterisation and sensing equipment. Published limits retain equipment and configuration qualifications. Embedded NewsArticle dates refer to an unrelated doctoral-supervision article and are not dates for this equipment page.
National Buried Infrastructure Facility | UKCRIC
The exact NBIF record identifies the University of Birmingham, near-full-scale research on buried systems, collaborative user groups, and the main pit with a 10 m by 5 m moveable section. Historical showcase presentation material is not used as a current equipment inventory.
The facilities page lists NBIF at Birmingham and explains early project discussions, intellectual-property planning and EPSRC-funded proposal priority. UKCRIC explicitly says it is not a lab service provider or accredited analysis service. Its general access route remains distinct from NBIF’s dedicated email.
