Foundation testing and engineering design are too often treated as separate line items, handled by different vendors, on disconnected scopes, with a handoff somewhere in the middle.

It can look cost-neutral on paper, but that separation introduces real risk: lost context, conservative guesswork, and slower decisions. Groundline Engineering closes that gap. The same team that performs your TDR testing also delivers the structural assessment and detailed design, one point of accountability, from field data to final recommendation.

What We Do

Groundline combines Time Domain Reflectometry (TDR) testing with structural engineering under one roof, one team, and one scope.

Testing through to design

‍

We take ownership of the full process, from condition assessment to final deliverables, and can re-evaluate or adapt without re-engaging outside firms.

Data interpreted by the people who design with it

‍

Our engineers work directly with the impedance signatures, stiffness gradients, and embedded length estimates they gathered themselves, so nothing gets lost in translation.

Near-real-time progression

‍

Test interpretation flows straight into engineering action, supporting go/no-go decisions on foundations in weeks, not months.

Standards-based, project-specific interpretation

‍

We apply TDR data against relevant design standards and actual loading conditions, avoiding

Documentation built for scrutiny

‍

Combined reporting and design packages trace a clear line from test data to engineering rationale to final recommendation, supporting capital and regulatory submissions.

The Results

One partner, total accountability. No finger-pointing between testing vendors and designers, just one team responsible for the outcome. 
‍
A direct line between data and decisions. The engineers designing your foundations are the same engineers who tested them. 
‍
Faster turnaround. Integrated delivery removes the lag between results and recommendations, so schedule-sensitive uprating and capital programmes keep moving. 
‍
Less scope creep, less rework. Every foundation gets the minimum effective solution, not an overcautious one driven by unfamiliarity with the data. 
‍
Stronger cost justification. Clear, defensible documentation that stands up to regulatory and internal review.

By unifying testing, analysis, and design, Groundline gives asset owners a streamlined, technically rigorous approach to foundation management, one that accelerates decisions, minimises waste, and protects the long-term value of capital investment.

Our Work

TDR Foundation integrity assessment

Transmission line uprating introduces higher loads to foundations originally designed for lower stresses, creating uncertainty around their suitability for continued service.

Groundline combines TDR testing with structure-specific engineering analysis to identify which foundations can be safely reused, retrofitted, or replaced, enabling targeted investment, reducing unnecessary civil works, and supporting confident, evidence-based upgrade decisions.
