Specialist consultancy for underground works, infrastructure inspection, structural assessment, temporary works and complex civil engineering, supporting projects from early strategy to construction and asset operation.
Senior specialist engineering input
Advice shaped by delivery reality
Rigorous, proportionate assurance
Transport, water, energy & civil works
We provide specialist engineering consultancy for tunnelling and other infrastructure projects, including inspection, structural assessment and modelling, remedial design, temporary works, and civil and geotechnical design. Our services range from targeted technical reviews and independent checks to defined design packages and ongoing support throughout project delivery.
01
Condition surveys, defect assessment and practical maintenance priorities for operational underground assets.
02
Inspection-led analysis, load assessment and strengthening advice for existing and proposed infrastructure.
03
Feasibility, methodology, design review and construction support for tunnels, shafts, caverns and underground structures.
04
Buildable temporary works design, review and Category 2 or 3 checking with clear interface management.
05
Constructability, sequencing, technical assurance and decisive support through complex delivery stages.
06
Coordinated engineering for foundations, retaining works, excavations, drainage, duct routes and permanent works.
Our work sits where technical detail meets project delivery. We can provide targeted advice on a defined problem, independent review of a design or methodology, or embedded support through a critical stage of a programme. Every commission is shaped around the client's decision, risk and required outcome.
The consultancy is led by Mehdi Hosseini, CEng FICE, CEng FIMMM and MAPM. His experience spans major tunnelling and underground infrastructure programmes, including technical leadership, engineering management, construction delivery and specialist review across transport, water and energy.
Our team applies experience gained across a wide range of infrastructure projects to develop practical engineering solutions that meet each project’s requirements and site conditions
Our experience spans sectors where underground, structural and construction risks have direct consequences for safety, programme, service continuity and whole-life performance.
The common thread is complex engineering under constraint. We bring specialist judgement to interfaces between ground, structure, construction sequence and operational need.

Selecting the right tunnelling method is one of the most critical decisions in underground construction. Every project has unique challenges, including geological conditions, tunnel size, depth, groundwater conditions, environmental restrictions, construction timelines, and budget limitations. Among the commonly used tunnelling
Tunnel principal inspections play a vital role in maintaining the safety, reliability, and long-term performance of underground infrastructure. These detailed inspections provide a comprehensive assessment
Effective tunnel maintenance begins with understanding defects and converting inspection findings into practical, risk-based actions. Tunnels are long-term infrastructure assets exposed to various challenges, including
