Looking for an independent quantum and delay expert for a construction dispute?
Build Conex provides independent quantum and delay expert reports for construction disputes across Australia. Whether you’re dealing with a delay and disruption claim, a variation dispute, or a dispute over quantum, Build Conex offers one expert, one methodology, and a court-ready report backed by real project experience.

Why Choose Build Conex?
No reconciling reports. No conflicting assumptions. Just one disciplined opinion.
At Build Conex, the focus is on giving law firms and their clients evidence that holds together under cross-examination. Reports aren’t built by stitching together separate planners, quantity surveyors, and causation experts—one methodology covers causation, delay, and quantum from the same foundation.
- ✅ One report, one methodology – Causation, delay and quantum addressed together, not by three different experts with three different assumptions.
- ✅ Forty years of project experience – Our Principal has worked as design engineer, project manager and claims manager on some of Australia’s largest construction projects.
- ✅ Evidence tested against the records – Contemporaneous records are tested first; assumptions and overstated claims are identified and reduced where the evidence doesn’t support them.
- ✅ Court-ready and cross-examined – Our Principal, Albert Merolla, is prepared to sit in the box and defend the report personally.
- ✅ No junior between you and your matter – Every report is led by Albert personally, deliberately lean, with no tier-one bureaucracy.
From the first review of the dispute through to giving evidence at trial, Build Conex works to make the expert evidence disciplined, defensible, and clear.
About Build Conex

Build Conex was founded with a simple goal: to give Australian litigation law firms and their clients construction dispute evidence that can actually withstand cross-examination. The team understands that when quantum, delay and causation reports come from separate experts working to separate assumptions, cases weaken under pressure—not because the client is wrong, but because the evidence wasn’t built to hold together.
Led by Albert Merolla—Chartered Engineer, Chartered Quantity Surveyor, forensic delay analyst and Registered Adjudicator—Build Conex has provided independent expert reports and testimony across civil, building, mining, and oil and gas disputes in Australia, the Middle East and the United States. Albert has led teams on some of the largest disputes globally, including a $5.5 billion USD claim on the Riyadh Metro Project, and has resolved matters ranging from multi-million dollar variation disputes to complex remeasurable contracts.
The business works with litigation law firms and their clients across Australia. If you’re looking for a construction dispute expert who tests the records, gives evidence with certainty, and stands behind the report personally—this is a great place to start.

Frequently Asked Questions
What is a quantum and delay expert report, and why do I need one?
A quantum and delay expert report is independent evidence used in construction disputes to establish what caused a delay or cost overrun, how the delay should be analysed, and what amount is actually owed under the contract. Courts and tribunals rely on this evidence to test claims for variations, prolongation costs, and disruption. Build Conex provides this in one report covering causation, delay and quantum together, rather than requiring separate experts.
Why use one expert instead of separate specialists for delay, quantum and causation?
When separate experts prepare causation, delay and quantum reports independently, their assumptions often don't align — and under cross-examination, those gaps can weaken an otherwise strong case. Build Conex builds all three elements from the same contemporaneous records and the same methodology, so the evidence holds together when it's tested in the box.
What size or type of construction disputes does Build Conex handle?
Build Conex has provided expert reports and testimony on disputes ranging from single-digit million-dollar variation claims to some of the largest construction claims globally, including a $5.5 billion USD dispute on the Riyadh Metro Project. Matters span civil, building, mining, and oil and gas projects across Australia, the Middle East, and the United States.
Will Albert Merolla give evidence in court, or just prepare the report?
Both. Albert prepares every report personally and is also prepared to sit in the box, defend his reasoning, and be cross-examined on the methodology. There is no junior standing between the report and the matter — the person who wrote the report is the person who defends it.
