Inspection of structural feasibility for floor addition by an engineer

The first step of a home extension project is the inspection of feasibility by a structural engineer. Even before to do any sketches or plans it is necessary to know to what extend the existing building can add another floor and at what price of structural reinforcements: addition of timbers, foundation piles, enlargement of footing, correction of foundation or others.

The engineer will take several measurements and if necessary will require the help of a specialized soil laboratory in order to better know the structure and its environment. Such as: ground test, measurement of the footing and of the foundation and the composition of the concrete, kind of wood frame building and of other existing structural elements. All these elements are necessary in order to know if structural reinforcements are needed prior to add a new floor. Daniel Dargis engineer and his team take care of the feasibility inspection, the calculation and of the analysis in order to first inform the clients about the possible solutions.

Inspection of a home extension

The inspection of the structure during the work is an important step in order to be sure of the quality of the job so a compliance letter can be written at the end of the work. Many times the clients are not present during specific important moments of the construction, such as: the digging, pouring of concrete for the foundation and during the assembly of the structure. It is useful to have an impartial engineer present at specific moment of the construction work.
