Complex Assets.
Clear Decisions.
Evidence-based structural engineering for Brisbane, Gold Coast & Southeast Queensland. Make Safe and Monitor strategies that protect capital and extend asset life.
Trusted by Asset Owners, Managers, Architects, and Engineers
Experienced
Decades of combined engineering knowledge across multiple sectors inform practical, efficient solutions. Our breadth of design and investigation experience delivers outcomes grounded in real-world constraints and proven methodologies.
Ready & Reliable
Consistent, dependable service backed by proven methods. TRSC is available to respond immediately during times of need, stress, or emergencies, providing expert structural engineering support when it matters most.
Collaborative
TRSC integrates engineering services within multi-partner projects. We respect existing stakeholder roles, coordinate across disciplines, and deliver outcomes aligned with project goals and timelines, partnering with engineers, not competing with them.
Structural Engineering
Across Every Discipline
Structural Investigation
NDT, material sampling & analysis through NATA-accredited partner laboratories. Evidence-based investigation that determines proportionate intervention.
Learn more →Dilapidation & Condition Assessment
Pre-construction dilapidation surveys and risk-classified condition assessments per AS/NZS ISO 31000:2018. Baseline evidence for Make Safe and Monitor decisions.
Learn more →Root Cause Analysis
Systematic determination of why a defect occurred, not just what is wrong, but the mechanism driving it. Prevents remediation that treats symptoms instead of causes.
Learn more →Materials Testing
Concrete coring, chloride profiling, carbonation depth, petrographic analysis, and steel section loss assessment. NATA-accredited laboratory partners.
Learn more →Durability Modelling
Chloride ingress and carbonation front modelling to predict when reinforcement corrosion will initiate. Forecasts condition 10, 25, and 50 years forward.
Learn more →Residual Design Life Assessment
Quantified remaining service life for each material system. Enables capital planning over 25, 50, and 75-year horizons based on tested material properties.
Learn more →Remediation Design
Targeted solutions restoring capacity and durability, sequenced to minimise operational disruption. Phased programmes aligned with capital planning.
Learn more →Disaster Response
Emergency structural assessment within 48 hrs. From Q1 Spire to coastal storm damage, we mobilise fast.
Learn more →LiDAR & BIM Integration
3D laser scanning and building information modelling for complex assets where drawings don't exist.
Learn more →Structural Monitoring
Real-time sensor networks for long-term movement tracking. Evidence base for capital planning decisions.

Who determines the extent?
Standard engineering reports identify every visible defect, as they should. But without quantifying how far each defect extends and how severe it actually is, remediation contractors price the worst case. Contingencies stack. Costs escalate. And the asset owner pays for uncertainty, not condition.
We determine the extent and severity of every defect before it reaches a remediation quote, enabling efficient works executed over time, targeting critical areas when required instead of pricing everything at once.
Marina Mirage
Coastal Wharves
A 37-year-old marine boardwalk approaching its design life, with a major redevelopment planned. Rather than default to full demolition, TRSC's three-stage investigation and Make Safe & Monitor approach is keeping the infrastructure serviceable during refurbishment, reducing project costs significantly through targeted intervention instead of blanket replacement.
Projects That Define the Practice
Real People.
Real Outcomes.
We Take On The Risk
As investigative engineers, we target high-risk projects requiring specialised expertise. We assess deteriorated structures, fire-damaged buildings, and heritage assets where standard approaches are insufficient.
Availability
We mobilise immediately for time-critical situations: sudden deterioration, regulatory notices, compliance deadlines, or project delays. When the structural question is urgent, we respond without delay.
Experience
Our team brings decades of combined experience across investigations, engineering, and construction, including heritage buildings, fire-damaged assets, and aging infrastructure.
Collaboration
We partner with incumbent engineers rather than compete. Our specialised investigation and heritage expertise complements existing consultant capabilities.

Make Safe
& Monitor
Most structural failures are preceded by warning signs. TRSC's five-level hierarchy begins with making a structure safe and monitoring its behaviour, not defaulting to expensive remediation before the evidence demands it.
This evidence-first philosophy consistently identifies proportionate intervention scopes, replacing conservative assumptions with measured data while maintaining strict compliance with Australian standards.

Behind Complex Assets
TRSC was founded by Lachlan Pagan, a chartered structural engineer with registrations across Queensland, New South Wales, and Victoria. The practice was built on a single premise: that existing assets deserve rigorous engineering attention, not conservative over-specification.
Every recommendation is backed by physical testing, laboratory analysis, and documented evidence, delivering outcomes that protect capital while meeting every relevant Australian standard.
