TerraGraphics provides Electrical Design of low and medium voltage systems. TerraGraphics’ staff experience includes electrical distribution system design for new installations as well as modification to existing facilities that meet industry codes and standards, and client-specific design criteria. Expertise includes low voltage (<600 VAC) power distribution systems design, short‐circuit and arc flash incident energy calculations, load flow and voltage drop analysis, lighting analysis, motor control, grounding, and equipment specification. TerraGraphics’ staff includes electrical engineers with an average of more than 20 years of experience in the areas of electrical design (pre-conceptual to definitive design), engineering support during construction, testing support, and general field support (walk-downs, as-builts, etc.).


TerraGraphics provides Mechanical Design for plants, facilities, and equipment. Expertise includes piping (ASME B31.1, B31.3, B31.9), tanks and pressure vessels (ASME B&PV and API), heating, ventilation and air conditioning (ASHRAE), and nuclear applications (ANSI N13.1, ASME N509, N510, AG 1). TerraGraphics engineers are experienced in developing design drawings, preparing equipment specifications and conducting engineering analysis for all phases of design including scoping, conceptual, and definitive design. Design projects range from large production facilities to small specialized equipment. Experience includes equipment procurement, installation and site construction, as well as the start-up, testing, and operation of plants and facilities.



TerraGraphics Structural Design services include providing design and evaluation of equipment for natural phenomena hazards (NPHs). These services have included the stress and structural evaluation of various planned modifications and proposed enhancements of nuclear waste facilities, as well as the analyses of piping/equipment supports and restraints. TerraGraphics engineers are experienced in the application of finite element analysis and applying the applicable codes and standards (DOE-STD-1020, IBC, AISC, ASCE 7).



Terragraphics Designers and Drafters have diversified skills and knowledge of construction documents and computer assisted drafting and design. Experience includes the use of AutoCAD 2D and 3D, as well as SolidWorks for developing 3D renderings.
