Construction & Engineering Expert Witness Services
Construction & Engineering
At Masin, we provide specialist Expert Witness services across the full range of construction and engineering disputes—be it in litigation, arbitration, or alternative dispute resolution. Our experts are internationally recognized for their deep technical knowledge, commercial understanding, and ability to deliver independent, well-reasoned opinions rooted in extensive real-world experience.
Why Contracts & Claim Management
Disputes are expensive, delays are disruptive, and unclear contracts can cost you. Our consultancy helps mitigate these risks. We guide you in drafting stronger contracts, managing changes with precision, and preparing claims that stand up in negotiations and tribunals. Backed by data, strategy, and deep sector knowledge—your contracts become your strongest shield.
What We Do
We support clients across infrastructure, energy, oil & gas, transport, real estate, and industrial sectors. With professionals who have worked on some of the world’s most complex capital projects, we understand both the technical intricacies and practical realities that shape these disputes.
Our Construction & Engineering Expert Witness services are offered through two core disciplines: Delay and Quantum.
Delay Experts
Delays are one of the most common causes of dispute in construction and infrastructure projects. These delays can arise from a variety of causes, including scope changes, design errors, late approvals, resource constraints, or force majeure events. In the often complex web of causation and liability, the need for a structured, independent delay analysis becomes paramount.
Masin’s Delay Experts are highly experienced in carrying out forensic delay analysis across a range of project types, including:
- High-rise buildings
- Oil & gas facilities
- Rail and metro systems
- Power plants
- Airports, ports, and highways
Delay Expert Services
We apply industry-standard methodologies such as Critical Path Method (CPM), Time Impact Analysis (TIA), and Windows Analysis to assess delay causation, apportion responsibility, and quantify time-related impacts. Our delay expert services include:
- Independent forensic delay analysis
- Evaluation of Extension of Time (EOT) claims
- Analysis of concurrent delays and acceleration measures
- Assessment of critical path changes and float ownership
- Preparation of delay expert reports for litigation/arbitration
- Expert testimony and cross-examination support
Masin’s delay experts bring not only technical knowledge but also clarity and strategic thinking to contentious forums. We tailor our approach to suit the procedural nuances of international arbitration and court proceedings.
Quantum Experts
Quantum disputes in construction typically revolve around cost entitlement, valuation of variations, damages from delays, disruption, and termination, or alleged defects. Our Quantum Experts bring a structured, evidence-based approach to evaluating financial claims arising out of construction and engineering projects.
We work across a wide range of cost and commercial disputes, including:
- Valuation of change orders and variations
- Prolongation, disruption, and loss of productivity claims
- Termination cost assessments
- Claims involving defects, remedial works, and diminution in value
- Damages assessments including consequential and indirect losses
Quantum Expert Services
Masin’s Quantum Experts combine deep commercial acumen with advanced analytical tools and industry-standard costing databases. Our services typically include:
- Detailed evaluation of contractor claims and counterclaims
- Independent assessment of cost entitlement and pricing mechanisms
- Valuation of work done, preliminaries, and overheads
- Assessment of as-built vs. planned productivity and output
- Forensic accounting and cost validation
- Preparation of quantum expert reports and expert evidence
- Testimony before arbitral tribunals and courts
Our quantum experts are known for their ability to present complex costing and valuation matters in a clear, structured, and persuasive manner—grounded in robust documentation and analytical rigor.
