Collection and evaluation of subsurface soil, rock, and groundwater data to determine the physical properties and engineering behavior of the ground at a proposed construction site. This information is essential for ensuring that the foundation and other structural elements are designed to be safe, stable, and cost-effective.

The evaluation of excessive settlement of foundations is critical to ensuring the safety, stability, and functionality of a structure. Excessive settlement, whether it occurs immediately or over time, can lead to a range of problems, from minor cosmetic issues (such as cracks in walls) to serious structural damage that compromises the building’s integrity.

The purpose of this survey is to determine the relative elevation differences across the slab of the building, identify potential areas of settlement, and assess any signs of distress or deformation that could compromise structural integrity.

Underpinning is a method used to strengthen or stabilize an existing foundation by extending it to a deeper, more stable layer of soil or improving its load-bearing capacity. It is typically required when the original foundation is no longer able to adequately support the structure, due to factors such as settlement, changes in load, or excavation around the foundation.

Foundation design encompasses a variety of systems suited to different structural needs and soil conditions. Shallow foundations, such as spread footings, strip footings, mat foundations, slab-on-grades, and post-tensioned slabs. Deep foundations, including pile foundations, drilled piers, helical piles. 

Earth Retaining Structures are  are critical in maintaining stability for landscapes, roadways, and construction projects, especially on sloped terrains or where changes in elevation are necessary. Some common types of earth retaining structures include: Gravity Retaining Walls, Cantilever Retaining Walls, Sheet Pile Walls, MSE Walls.
