Project Experience

Government Contract Projects

Mr. Evans was retained by a design-build contractor to prepare a schedule delay analysis for the engineering, procurement, construction and commissioning of two Air Force Base hotels. Primary issues included the Government managing a design-build contract as a design-bid-build project, design deficiencies in the Government’s 35% concept design, protracted review of design drawings and material submittals, differing site conditions, and project closeout issues. Mr. Evans testified at trial.

Mr. Evans was retained by a general contractor to prepare a schedule delay and cost overrun analysis for an odor control facility as part of the Chicago Deep Tunnel project. The issues included the Government’s defective specifications, engineering drawing errors and omissions, differing site conditions and Government specified equipment that failed during commissioning. Mr. Evans testified at trial.

Mr. Evans was retained by a government contractor to prepare a schedule delay and labor disruption analysis for a $300 million missile production contract. The Government had changed the critical environmental specifications during mid-production impacting engineering and fabrication of the guidance section that resulted in delay and labor disruption on the factory floor.

Power Generation Projects

Mr. Evans has been retained by engineering firms, contractors and equipment suppliers to prepare schedule delay analyses for over sixteen coal and gas-fired power plant projects over the past twenty years. The issues include late and incomplete engineering, differing site conditions, labor productivity, equipment failures, start-up and commissioning and the cumulative impact of design changes.

Mr. Evans has provided cost and schedule construction progress reviews for coal and gas-fired power plants as part of an independent audit firm. This work included assessments of the contractor’s risks and mitigation strategies, availability of qualified craft manpower, critical path schedule forecasts, status of critical overseas equipment procurement deliveries and verification that the costs incurred were in balance with physical progress. 

Offshore Petrochemical Projects

Mr. Evans was retained by an international design-build contractor to prepare a schedule delay analysis for two Brazilian owned FPSO (Floating Production Storage Offloading) facilities delayed 22 months and $750 million over budget. Issues included design deficiencies in the Owner’s concept design, late and incomplete vendor data to complete detail design, labor strikes, incomplete equipment deliveries, Customs delays, and commissioning issues. 

Mr. Evans was retained by an international contractor in Brazil to determine the underlying issues that resulted in a $25 million cost overrun and three-month schedule delay during the refurbishment of a deep water drill ship. The study identified lessons learned to mitigate cost and schedule issues for the contractor’s future refurbishment projects.

Hospital Design and Construction Project

Mr. Evans was retained by outside counsel for the Architect/Engineer to prepare a schedule analysis of the Owner’s allegations that late and incomplete design drawings was responsible for delay and cost overruns to a $950 million replacement hospital. The issues included the Owner’s late procurement of imaging equipment and continuous equipment design changes that delayed the contractor’s coordination and detailing activities. 

Commercial Building Projects

Mr. Evans was retained by the general contractor to prepare a schedule delay analysis of an 18 story hotel / theater / 58 story high rise condominium in Chicago. Issues included late and incomplete (Owner) furnished engineering and late Owner furnished material. The Owner also directed the contractor to perform out-of-sequence work based on actual condominium purchases that resulted in significant labor disruption and cost overruns.

Mr. Evans was retained by outside counsel for a state university to prepare a construction manager standard of care analysis, schedule delay analysis and provide trial testimony regarding the impact of structural design omissions and other events that delayed the completion of a high-rise residence hall building. 

Nickel Mine and Refinery Project – Madagascar


Mr. Evans was retained by the project Owner to prepare a cost and schedule risk review for a $4 billion nickel mine and refinery project that ultimately grew to $7 billion at completion. Mr. Evans found late P&ID engineering drawings would impact equipment procurement activities, the completion of detail engineering and the start of construction. Late and incomplete engineering was the primary risk for cost and schedule overruns in subsequent engineering, procurement and construction activities.
