Once plans have been drawn up and approved by the client, an engineering contractor uses their professional expertise to organise human and material resources on site, and ensure the project runs to time and budget and is safe to work on. Occasionally, contractors will put together a design and build a team themselves. This blurs some of the boundaries between the services they offer and those traditionally provided by consultants.
The work involves turning the designer's plans into reality by actually building them. Contracting engineers ensure that all aspects of the construction project under their responsibility - from ground works and foundations to final finishes - are completed within cost and time constraints and to client specification.
