Geotechnical engineering is a branch of civil engineering that
determines the engineering behavior of earth materials.
What is Geotechnical Engineering?
7
Principles of soil and rock mechanics are used to investigate subsurface conditions and materials to: Determine the relevant physical/mechanical and
chemical properties of these materials; Evaluate stability of natural slopes and man-
made soil deposits; Assess risks posed by site conditions; Design earthworks and structure foundation; Monitor site conditions, earthwork and
foundation construction.
Geotechnical Engineering
8
Develop an accurate & thorough evaluation of site characteristics (good data)
Effectively communicate data to owner’s agent
Offer professional opinions regarding results—parameters used in design process
Become a trusted partner early—carry through to project completion

Thorough plan and spec review Pre-Construction Meeting,
Logistics, and Construction Safety Phasing Plan Discussions
Building a good working relationship with your Airport, Engineering Consultant & Contractor.
Constant Communication with Project Team
Successful Project Start Up
20
During the construction phasing, the project engineer and testing group oversees your project so it will; Comply with the design and specifications as well as FAA,
state, and local regulations. Provide certified staff to evaluate, test, and report results
during all phases of the project. Assure accredited labs are performing acceptance testing
per project specifications. Comply with all Safety hazards and concerns at all times.
