The three main areas of construction professional may seem all the same to the someone outside the business.
All three may have some input within a given project, but actually they will all have very slightly different perspectives. Architects are interested in the aesthetic appearance of a project; surveyors are interested in the the value and use of the land, and engineers are interested in the strength and stability of all of the structural elements.
In times gone by, an architect was in charge of the builders on a project: The training of the modern architect still focuses on the appearance and function of the building and also the spaces within it, but additionally architects can be the 'lead consultant' for a project, meaning that they will direct all of the activities of the builders and the other professional designers, and are therefore ultimately responsible for every aspect of the work.
If your project requires consideration of aesthetics and use of spaces, you may need an architect.
The surveyors' profession has many divisions:
If there are issues around the use and tenure of your land, neighbours, or construction costs, you may need to consult a surveyor.
Originally they were designers of 'engines of war', engineers are now divided into more specialist disciplines, such as civil, chemical, mechanical, software, electrical, electronic and structural.
The things they all have in common is that they use science and mathematics to solve real problems.
Structural Engineers are concerned with the strength and stability of all of the individual elements of the construction – the solid members between an architect's 'spaces', such as the floors or walls between the rooms.
If you need assistance with the strength or stability of any structure, you need to engage a Structural Engineer
