Transmission and distribution

Access is available to the extensive resources of one of the world’s leading engineering consultancies through our team of transmission and distribution specialists.

Our technical strength is supported by our independence and ability to take a wide view of the entire project in its complete environment.

Owner’s engineer

For utilities and private sector developers, we provide services through all stages of project development for both new projects and plant refurbishment and uprating. Our services cover every element from initial reconnaissance, feasibility and environmental impact studies, through electrical, mechanical, and civil design and commercial and technical contract documentation, to project management and supervision of implementation. In addition, we offer services in asset management and valuation, economic, financial, and legal assessments and plant optimization.

Our technical strength is supported by our independence and ability to take a wide view of the entire project in its complete environment.

Lender’s engineer

Prior to financial close, we work closely with lenders and sponsors to address all the technical and environmental issues relevant to financing and to understand how the business and assets operate.

We provide clear analysis and focused conclusions to clearly address the financing from a technical and environmental perspective. Once financial close has been achieved, we provide a monitoring service for both the construction work and the provision of equipment. We support the lenders through testing and commissioning of the assets and in monitoring their ongoing operation.

Specialist services

A wide variety of problems can affect power systems at any time from commissioning to refurbishment. Remedial works need to be investigated, options assessed, and target investments identified.

Mott MacDonald offers specialist services in problem resolution, failure analysis and forensic engineering through risk and asset management, failure effect analysis, and reliability assessments. By providing these skills through our power systems expertise, we can deliver the most appropriate solution to any problems encountered.

Interface engineering

Today’s market requires increasingly complex contracts for construction and equipment supply within tight timescales and margins. We offer services in the management of interfaces between designers, suppliers and constructors. These interfaces can pose a huge obstacle to successful achievement of both new build and refurbishment contracts, at the tender stage and during implementation. Our services are designed to minimize the risks so that the management of subcontractors and strategic partners is technically and commercially effective.
