Al Jazzar engineers evaluate the subsurface conditions at project sites, and determine the suitability of site conditions for earthwork and foundation construction

In “The Influence of Modern Soil Studies on the Design and Construction of Foundations”, Karl Terzaghi commented on foundations as follows:

On account of the fact that there is no glory attached to the foundations, and that the sources of success or failures are hidden deep in the ground, building foundations have always been treated as step children; and their acts of revenge for the lack of attention can be very embarrassing.

The comments made by Terzaghi are very significant and should be taken note of by all the practicing Architects and Engineers. It is still the usual practice of many Architects and Engineers. Rock Drilling for Foundation Design to have primary interest in the design and construction of the visible parts of buildings but not of foundations.

Architects or Engineers should make use of the growing knowledge of foundation design, to render true service for their profession. Since substructures are as important as superstructures, persons who are well qualified in the design of substructures should always be consulted and the old proverb that a ‘stitch in time saves nine’ should always be kept in mind

Geotechnical Engineering

Geotechnical engineering is a sub-discipline of civil engineering concerned with the behavior of earth materials. By understanding the principles of soil and rock mechanics, Al Jazzar engineers evaluate the subsurface conditions at our project sites, and determine the suitability of site conditions forearthwork and foundation construction.

Most construction sites require geotechnical services to move forward safely and cost effectively. Al Jazzar engineers conduct subsurface explorations to evaluate subsurface soil, rock and groundwater conditions at the site, evaluate foundation design and support requirements for the project. Our engineers evaluate existing site conditions, existing structures at the site, the nature of uncontrolled fills, response of the site when earthquake, estimation of settlement for structure loading, slope stability, and other challenges during preliminary design. Our engineers work with the design team members during final design to prepare plans and specifications.Our field geologist, technicians and engineers work with both the contractor and design team during construction to confirm subsurface conditions are consistent with those anticipated during design, resolve questions and issues that arise during construction, and to observe building foundations, retaining walls, earth fills, roads, tunnels, and other geotechnical-related project works are constructed as indicated in the contract documents.
