The purpose of ground investigation is to find out the ground conditions and their variations in the construction site. For further planning of the construction, we will find out the soil types, the compactness of the soil and variations within the site. Depending on the site, we will also make observations of the groundwater level and investigate the location of the bedrock surface.
The contents of the ground investigations vary from place to place, depending on the nature and challenges of the subject site. The contents of the ground investigations usually consist of different types of drillings, sampling, groundwater pipe installation, as well as trial pits or structural drillings. The need for a ground investigation and its extent is always evaluated by our responsible geotechnical designer.
EARLY GROUND INVESTIGATIONS AND THE PLANNING SOLUTIONS REGARDING IT WILL CREATE SAFE, HEALTHY AND COST-EFFICIENT CIRCUMSTANCES FOR NEW CONSTRUCTION, AS WELL AS FOR REBUILDING SUBJECTS.

Soil laboratory investigations
The taking of soil samples and their analysis always belongs to an accurately made ground investigation. It is not possible to estimate the features of the soil through just borehole logs, therefore soil samples are also taken during drillings, of which, at least, the soil type, granularity and water content will be investigated.
It is important to begin the site’s geodesign process immediately during the project planning phase, when the area’s soil applicability for construction can be investigated and the limits for a site preparation can be set.
The purpose of geodesign is to provide design values regarding the planning of the project to an architect, as well as to a structural engineer. In addition, a geodesigner also works closely, according to the definition of the work, with an HVAC, electrical and area designer, considering the subject’s soil environment and the challenges that it brings to the area’s functionality.
IT IS IMPORTANT TO CARRY OUT GROUND INVESTIGATIONS AT THE EARLY STAGE OF THE PROJECT RIGHT AFTER FINISHING OF THE PROJECT'S FIRST DRAFTS. THE REQUIREMENTS REGARDING EXCAVATION WORKS CAN BE SET AT THIS STAGE AND STEER THE PROJECT THIS WAY TOWARDS COST-EFFICIENT SOLUTIONS.
WHEN THE PROJECT MOVES FORWARD, SITE PREPARATION PLANS ARE UPDATED ACCORDING TO THE Site’S REQUIREMENTS, IN COOPERATION WITH THE ARCHITECT, STRUCTURAL ENGINEER, AND OTHER EXPERT PLANNERS.
Quality control of the construction site
Soil and site preparation requires quality control, like all other construction work phases that take place above the ground. If the foundations do not reach the quality requirements that are set or they are exceeded, the repair costs may be extensive or use of the building could even be prohibited.
The quality control of the soil preparation is usually performed with density/moisture gauge (Troxler) or bearing tests (plate loading test). The requirements of the quality control tests will be approved by our responsible geodesigner.
