Turning complex contracts, schedules, and budgets into predictable project success. Over 30 years of leadership in engineering
At a Glance
Aldo Dórea Mattos—civil engineer, lawyer, MSc, FAACE, and six-time author—has spent 30 years rescuing high-stakes projects from overruns, claims, and stalled progress. He has managed or advised contracts above US $600 million on four continents and trained more than 10 000 professionals. His dual technical-legal lens lets owners, contractors, and investors speak the same risk-aware language from the first RFP to the final payment certificate.
Contract Management
We convert clauses into clarity and cash flow.
- FIDIC / NEC conditions of contract tuned to Brazilian Law 14 133/21 and ABNT norms.
- Baseline risk register, early-warning notices, and Dispute Avoidance & Adjudication Boards.
- Delay, disruption, and quantum claims built on CPM window analysis and earned-value evidence.
- Expert witness files ready for ICC, CAM-CCBC, or ICCA rules.
Result: fewer surprises, faster resolutions, stronger margins
Planning & Project Controls
Schedules that forecast—rather than forensically record—your future.
- ISO-aligned WBS and resource-loaded CPM, Line-of-Balance, and Time-Location charts.
- Lean Construction + Last Planner System®
- Real-time Schedule Performance Index (SPI) and To Complete Performance Index (TCPI) via Earned Value Management.
- DCMA 14-point and GAO Health Check dashboards.
Result: data-driven decisions weeks before delays hit the critical path.
Cost Engineering
Budgets you can take to the board—and the bank.
- AACE Class 5→1 estimates, Monte Carlo range analysis, and management reserve modelling.
- Control accounts linked to the OBS, BAC vs EAC tracking, and CPI/SPI triggers.
- Productivity benchmarking with AACE RP 25R-03 and constructability reviews that translate site realities into cash savings.
Result: transparent forecasts, rapid variance recovery, higher return on capital.
Technical Expert Reports
Evidence that stands up—in negotiations, arbitration, or court.
- Forensic Schedule Analysis per AACE RP 29R-03 and SCL Delay & Disruption Protocol.
- Independent cost, productivity, and contract-compliance audits.
- Concise exhibits and expert testimony accepted by tribunals worldwide.
Result: a clear, defensible narrative backed by hard numbers.
