Civil engineering software covers an increasingly broad part of the engineering workflow, from structural modeling and design to project documentation. But geotechnical engineering introduces a different set of problems. Soil is not simply another structural material, and a foundation model is not the same thing as a complete understanding of the ground beneath it.
So, can civil engineering software handle geotechnical analysis? Yes—but only when it is built to work with geotechnical data, soil behavior, field investigation results, and the design workflows required by actual geotechnical projects. General structural software may account for loads, foundations, or certain forms of soil–structure interaction, but that alone does not constitute a complete geotechnical workflow.
This distinction becomes especially important for civil engineering firms that primarily work on superstructure design but also undertake foundations, excavation support systems, ground improvement, or other geotechnical scopes. The goal is not to blur the boundary between structural and geotechnical engineering. It is to equip the right engineering expertise with the right tools to carry a geotechnical project from site data to analysis, design, drawings, and reporting.
Structural Engineering and Geotechnical Engineering Solve Different Problems
Structural and geotechnical engineering meet at the foundation, but they approach the project from different directions. Structural engineering is primarily concerned with how a structure carries and transfers loads safely. Geotechnical engineering deals with what happens when those loads reach the ground—and whether the ground, foundation system, excavation, or surrounding soil can safely accommodate them.
That distinction also defines what engineers should expect from their software. A structural analysis model may include foundation restraints or simplified representations of soil behavior, but this is different from building a geotechnical model from subsurface investigation data and carrying it through analysis and design.
What Structural Engineering Software Typically Handles
Structural engineering software is built around the behavior and design of the superstructure. Depending on the platform and project type, its core responsibilities typically include:
- Structural loads and load combinations
- Internal forces and member forces
- Reinforced concrete and steel design
- Structural deformation and displacement
- Superstructure modeling
- Building response under static and dynamic loading
The ground is certainly relevant to these calculations, particularly when defining supports and evaluating soil–structure interaction. However, the soil itself is generally not the primary engineering system being investigated.
What Geotechnical Engineering Software Needs to Handle
Geotechnical software starts from a different point: the ground cannot simply be treated as a predefined support condition. Its properties must first be established from site investigation and engineering data before its response to foundations, excavations, slopes, and other interventions can be evaluated.
A complete geotechnical workflow may therefore need to account for:
- Soil stratigraphy and individual soil layers
- Borehole locations and profiles
- Groundwater conditions
- Physical and mechanical soil parameters
- SPT, pressuremeter, and other field investigation data
- Foundation bearing capacity
- Immediate and consolidation settlement
- Soil–structure interaction
- Liquefaction potential
- Slope stability
- Excavation support systems
- Ground improvement systems
This difference becomes particularly clear at the data-input stage. SETAF2018, for example, allows engineers to define multiple boreholes and soil or rock layers and incorporate depth-dependent Standard Penetration Test (SPT) and Menard Pressuremeter Test (MPM) profiles into the geotechnical model.
That is the fundamental distinction: structural software primarily analyzes the structure and the loads it transfers; geotechnical software must also understand and model the ground receiving those loads.
So, Can Civil Engineering Software Perform Geotechnical Analysis?
Civil engineering software can perform geotechnical analysis when it includes dedicated tools for modeling subsurface conditions and evaluating soil-related engineering problems. General structural analysis capabilities alone are not enough; geotechnical projects require soil parameters, field investigation data, specialized calculation methods, design checks, and project-specific reporting.
The important distinction is therefore not simply whether a program can perform a soil-related calculation. The question is how far it can carry the geotechnical project. There is a considerable difference between entering a soil spring beneath a structural model, calculating foundation settlement, and managing an integrated workflow that begins with site investigation data and ends with engineering deliverables.
| Software Capability | What It Means in Practice |
| Basic soil inputs | Soil springs, allowable bearing assumptions, subgrade parameters, and basic foundation inputs used primarily to support structural analysis |
| Specialized geotechnical analysis | Dedicated calculations for settlement, bearing capacity, slope stability, liquefaction, excavation support, and other soil-related engineering problems |
| Integrated geotechnical workflow | Site investigation data → ground model → analysis → design checks → drawings and quantities → geotechnical reporting |
For an engineering office taking on geotechnical work, that third level can make a significant difference. A project rarely ends when a calculation produces an acceptable factor of safety or settlement value. The results still need to become a design, the design needs to become drawings and quantities, and the engineering decisions need to be documented in a traceable report.
This is where an all-in-one geotechnical software approach becomes particularly valuable: instead of treating each calculation as an isolated task, the software becomes the environment in which the geotechnical project is developed and delivered.
When Does a Civil Engineering Firm Need Dedicated Geotechnical Software?
Not every civil engineering firm needs dedicated geotechnical software. If a firm’s responsibility ends with the superstructure and geotechnical inputs are provided by another project team, its existing structural tools may be sufficient for that scope.
The need changes when the firm begins taking responsibility for the geotechnical side of the project itself. At that point, soil properties are no longer just external design inputs. They become part of the engineering problem that must be modeled, analyzed, checked, documented, and translated into project deliverables.
When the Firm Starts Taking Foundation Design Projects
Foundation design is often where the limitations of a structural-only workflow first become apparent. Knowing the loads transferred from the superstructure is only one part of the problem. Engineers may also need to evaluate bearing capacity, immediate and consolidation settlement, deep foundation behavior, and whether ground improvement is required.
The scope can quickly expand from shallow foundations to piles and micropiles, followed by solutions such as deep mixing, jet grouting, or stone columns.
This is where an all-in-one geotechnical software environment can reduce fragmentation. SETAF2018 supports the analysis, design, and drafting of shallow foundations, piles and micropiles, as well as deep mixing, jet grouting, and stone column applications.
When Excavation Support Becomes Part of the Project Scope
A building project does not begin at ground level. Deep excavations can introduce an entirely different engineering scope involving earth pressures, wall behavior, anchors, soil nails, supports, groundwater conditions, and adjacent structures.
Once the civil engineering firm becomes responsible for the excavation support system, a simple structural model is unlikely to represent the complete workflow required to design and document it.
SETAF2018 extends this workflow to bored pile walls, anchored excavation support structures, soil nail retaining structures, and reinforced concrete retaining walls, covering modeling, analysis, design, and drafting within the geotechnical project environment.
When Soil Conditions Affect Structural Decisions
The relationship between the two disciplines can be expressed through two closely connected questions:
Structural engineering asks: What loads reach the foundation?
Geotechnical engineering asks: What happens when those loads reach the ground?
The second question can influence the first. Excessive settlement, insufficient bearing capacity, weak soil layers, groundwater conditions, liquefaction potential, or the need for ground improvement can change the foundation concept and, in some cases, influence decisions made elsewhere in the project.
Dedicated geotechnical software becomes valuable here because the ground is no longer represented only by an assumed support condition. Boreholes, soil layers, groundwater, field investigation results, and engineering parameters can become part of the actual analysis model.
When Deliverables Go Beyond a Calculation
A bearing capacity value, settlement result, or factor of safety is not a completed geotechnical project.
Engineering firms ultimately need to turn calculations into design decisions and deliverables. Depending on the project, this can mean calculation details, design checks, drawings, quantities, tables, graphs, and the final geotechnical report.
This is also where the distinction between a specialized calculator and all-in-one geotechnical software becomes more meaningful. SETAF2018 connects analysis and design with project drawings, quantity takeoffs, and engineering reporting rather than treating them as unrelated outputs. Its drawing and quantity workflow can produce DWG drawings and XLSX quantity files, while its reporting environment can incorporate project data, calculations, tables, graphs, and engineering explanations.
For a civil engineering firm expanding into geotechnical projects, the need for dedicated software therefore begins not with the first soil calculation, but with responsibility for the complete geotechnical workflow.
What Geotechnical Analyses Should Civil Engineering Software Be Able to Perform?
Once a civil engineering firm takes responsibility for geotechnical design, the software needs to do more than represent soil beneath a structure. It should support the engineering questions that arise throughout the project: Can the ground carry the proposed loads? How much will the foundation settle? Is a deep foundation or ground improvement system necessary? Will an excavation remain stable? Is the site susceptible to liquefaction?
These questions involve different soil behaviors and design conditions, which is why a capable geotechnical analysis software should bring several analysis types into the same engineering workflow.
Foundation Bearing Capacity Analysis
Bearing capacity analysis determines whether the soil and foundation system can safely support the loads transferred by the structure. The required approach depends on whether the project involves shallow foundations, piles, micropiles, or other deep foundation systems.
For shallow foundations, established analytical methods remain fundamental to everyday geotechnical design. SETAF2018 calculates shallow foundation bearing capacity using the Terzaghi, Meyerhof, and Vesic methods, while also providing bearing capacity calculations for deep foundations.
For an engineering office, this matters because foundation design rarely begins and ends with a single allowable bearing pressure. Foundation geometry, soil stratigraphy, loading conditions, settlement requirements, and the possible need for a deep foundation system all need to be considered together.
Settlement Analysis
A foundation can satisfy bearing capacity requirements and still perform poorly if settlement becomes excessive. This makes settlement analysis a separate and equally important part of foundation design.
Depending on the soil conditions and project, engineers may need to evaluate:
- Immediate or undrained settlement
- Consolidation settlement
- Total settlement
- Settlement-time behavior
- Stress increases within the soil mass
SETAF2018 calculates settlement at user-defined settlement points while considering stress increments generated by the foundations within the model. Its calculation framework includes immediate and consolidation settlement, while consolidation parameters can also be used to generate settlement-time curves.
This allows settlement to be treated as part of the foundation-ground system rather than as an isolated calculation performed after the foundation has already been selected.
Deep Foundation and Ground Improvement Analysis
When shallow foundations cannot provide the required performance, the engineering question changes. The project may require loads to be transferred to deeper soil layers or the existing ground itself to be improved.
A complete foundation analysis software should therefore accommodate alternatives such as:
- Piles and pile groups
- Micropiles
- Deep mixing columns
- Jet grouting
- Rigid column systems
- Other ground improvement applications
SETAF2018 supports shallow foundations alongside piles, micropiles, deep mixing columns, jet grouting columns, and stone column applications within its foundation workflow.
The value of having these alternatives within one geotechnical environment is not simply convenience. Engineers can evaluate the foundation problem and the potential engineering response without separating every solution into a different project workflow.
Excavation Support Analysis
Excavation changes the stress conditions that existed before construction begins. As excavation depth and site constraints increase, engineers may need to evaluate earth pressures, wall behavior, support elements, surcharge loads, groundwater conditions, and earthquake effects.
The support system itself can involve several components. SETAF2018 provides modeling, analysis, design, and drafting capabilities for bored pile walls, anchored excavation support structures, soil nail retaining structures, and reinforced concrete retaining walls.
This is an important distinction for multidisciplinary civil engineering firms. Excavation support is not merely another structural wall calculation; it is a geotechnical problem in which the interaction between the retaining system and surrounding ground drives the design.
Slope Stability Analysis
For natural slopes, embankments, excavated faces, and similar ground geometries, the central question is whether the soil mass can maintain equilibrium under the conditions being analyzed.
A slope stability analysis software should therefore help engineers identify potential slip surfaces and determine the corresponding factor of safety using appropriate stability methods.
SETAF2018 performs slope and embankment stability analysis using limit equilibrium methods, including the determination of slip surfaces and calculation of safety factors. Its documented theoretical methods include OMS/Fellenius and Simplified Bishop.
Liquefaction Analysis
Liquefaction analysis introduces another type of geotechnical question because the assessment depends heavily on subsurface conditions, earthquake demand, and field investigation data.
This is why field data integration matters. A geotechnical software environment should not treat the liquefaction calculation as disconnected from the soil profile from which its parameters originate.
In SETAF2018, liquefaction resistance can be evaluated using Standard Penetration Test (SPT) data. The software also supports depth-based SPT profiles for individual boreholes, allowing field investigation data to become part of the project model rather than a value manually transferred between unrelated calculations.
Taken together, these capabilities illustrate what separates a few soil-related calculations from a broader geotechnical workflow. Bearing capacity, settlement, deep foundations, ground improvement, excavation support, slope stability, and liquefaction are different engineering problems, but they often belong to the same project. An all-in-one geotechnical software environment such as SETAF2018 is most valuable when it allows those problems to be addressed without losing the connection between the ground data, engineering model, analysis, and eventual design.
Why Analysis Alone Is Not Enough for Geotechnical Projects
A geotechnical project does not end when the solver produces a result. A bearing capacity value, settlement estimate, or factor of safety answers an engineering question, but it does not by itself deliver an engineering project.
The real workflow is much broader:
Site Investigation Data → Soil Model → Analysis → Design → Engineering Checks → Drawings → Quantity Takeoff → Geotechnical Report
Each stage depends on decisions and data produced earlier. Borehole information and field tests inform the ground model. The ground model provides parameters for analysis. Analysis results influence design decisions, and those decisions eventually need to appear consistently in calculations, drawings, quantities, and the final report.
This is where fragmented software workflows can become a practical problem. When soil data is maintained in one file, calculations are performed across several programs or spreadsheets, drawings are recreated in CAD, and reports are assembled separately, engineers repeatedly transfer the same project information from one environment to another. The issue is not simply the additional time involved; every manual transfer creates another point where project data can become disconnected from the engineering decision it supports.
An all-in-one geotechnical software approach addresses the workflow rather than only the calculation. SETAF2018 combines geotechnical analysis and design with project drafting, quantity takeoff, and reporting. Its documentation specifies that foundation and excavation-support drawings can be generated in DWG format, while quantity reports can be produced as XLSX files.
The reporting stage follows the same principle. SETAF2018 can generate general reports containing project data and analysis results, local reports that show calculations together with the equations used, and customizable geotechnical reports that incorporate text, tables, analysis and design data, and images.
That changes the role of the software. Instead of being a collection of calculators used at individual points in the project, it becomes an environment for carrying geotechnical data and engineering decisions through the project lifecycle.
For engineering firms taking responsibility for complete geotechnical deliverables, that continuity can be just as important as the analysis itself.
How SETAF2018 Extends a Civil Engineering Office into Geotechnical Project Workflows
SETAF2018 does not turn structural engineering into geotechnical engineering, nor does it remove the need for geotechnical expertise. What it provides is an all-in-one geotechnical software environment for firms that already have that expertise—whether through their own engineers, a dedicated geotechnical team, or a multidisciplinary project structure.
The practical difference is continuity. Instead of using one tool to interpret ground data, another for a foundation calculation, another for excavation support, and separate environments for drawings and reporting, SETAF2018 allows much of the geotechnical workflow to develop around the same project data.
1. Build the Ground Model from Site Investigation Data
A geotechnical model begins with what is known about the site, not with the foundation.
SETAF2018 allows engineers to define multiple boreholes and the soil or rock layers encountered within them. Borehole information can include coordinates and groundwater levels, while depth-dependent SPT and Menard Pressuremeter Test (MPM) profiles can be incorporated as field data for subsequent geotechnical analyses.
This creates a progression from:
Boreholes → Soil Layers → Groundwater → SPT / MPM Data → Material Parameters → Ground Model
For a civil engineering office expanding its geotechnical project scope, this is an important starting point: the soil model is developed from site-specific information rather than being reduced to a few assumed support parameters beneath the structural model.
2. Model Foundations and Geotechnical Structures
Once the subsurface conditions have been defined, the engineering structures interacting with that ground can be introduced into the project.
SETAF2018 supports shallow foundations such as raft, isolated, and strip footings as well as piles, micropiles, deep mixing columns, jet grouting systems, and stone column applications.
The same environment extends beyond foundations. Excavation support systems can include bored pile walls, anchors, soil nails, and reinforced concrete retaining walls.
This breadth matters because real projects do not necessarily fit into a single analysis category. A project may involve a foundation problem, ground improvement, and a deep excavation at the same site.
3. Run the Required Geotechnical Analyses
With the ground and engineering systems defined, the project can move into analysis.
Depending on the problem, SETAF2018 can be used for bearing capacity and settlement analysis, excavation support analysis, slope stability assessment, and liquefaction evaluation.
These analyses remain distinct engineering problems. The advantage of bringing them into one geotechnical software environment is not that they become one calculation, but that they can draw from a more consistent project model and data structure.
4. Move from Analysis to Design
This is where the distinction between a geotechnical calculator and geotechnical project software becomes important.
A calculator answers a defined question: What is the bearing capacity? What is the expected settlement? What is the factor of safety?
A project still has to answer the next question: What do we design based on those results?
SETAF2018 is structured around analysis, design, drafting, calculations, and quantity takeoff rather than analysis alone. This allows analysis results to remain part of the broader engineering workflow as foundation systems, excavation support structures, and other geotechnical solutions are developed.
5. Generate Drawings and Quantity Takeoffs
A design ultimately has to become something that can be documented and implemented.
SETAF2018 can generate engineering drawings for foundation and excavation support systems and export drawings in DWG format. Quantity reports can also be generated and exported as XLSX files.
For an engineering office, this reduces one of the common breaks in the project chain: completing the engineering calculations and then reconstructing their outcome separately for CAD and quantity takeoff.
The workflow can instead continue:
Analysis → Design → Drawing → Quantity Takeoff
6. Build the Geotechnical Report from the Same Project
Reporting is where SETAF2018’s all-in-one approach becomes particularly visible.
The software provides three reporting levels. General reports present project data and analysis results through tables and graphs. Local reports document individual analyses or design calculations and can include the equations used. Geotechnical reports provide a customizable reporting environment in which engineers can create their own sections and combine explanatory text with project data, analysis and design tables, and internal or external images.
That means reporting does not have to begin as a separate exercise after the engineering work is complete. It can remain connected to the calculations and design information developed throughout the project.
This is ultimately where SETAF2018 fits within a civil or multidisciplinary engineering office. It does not remove the boundary between structural and geotechnical engineering; it removes many of the unnecessary boundaries between the tools used to deliver a geotechnical project.
The result is a more continuous workflow:
Site Investigation → Ground Model → Analysis → Design → Engineering Checks → Drawings → Quantities → Geotechnical Report
That is the difference between software that performs geotechnical calculations and an all-in-one geotechnical software platform built around the project itself.
One Integrated Workflow vs. Multiple Engineering Tools
Geotechnical engineering will always involve different analysis methods, design decisions, and engineering checks. The problem begins when those differences also require the project data to be repeatedly moved between disconnected tools.
A fragmented workflow may keep borehole information in one file, foundation calculations in spreadsheets or separate analysis programs, drawings in CAD, quantity takeoffs elsewhere, and the final report in another environment. Each tool may perform its individual task well, but the engineer is left responsible for keeping the entire chain consistent.
For a civil engineering firm expanding into geotechnical work, this fragmentation can become particularly demanding. The firm is not simply adding a new calculation to its existing workflow; it is taking responsibility for a new project scope with its own data, analyses, designs, drawings, and documentation.
| Fragmented Workflow | Integrated Geotechnical Workflow |
| Borehole and site investigation data stored separately | Project-based ground and borehole data |
| Calculations distributed across spreadsheets and specialized tools | Multiple geotechnical analyses within the project environment |
| Results manually transferred between calculations | Project data remains available across related engineering tasks |
| CAD drawings prepared separately from analysis | Engineering drawings generated from project and design data |
| Quantities calculated in a separate workflow | Quantity outputs connected to the designed systems |
| Final report assembled from multiple sources | Analysis and design data incorporated into the geotechnical report |
This is the workflow problem SETAF2018 is designed to address. Its value as an all-in-one geotechnical software is not that every geotechnical problem becomes identical or that engineers no longer need specialized engineering judgment. It is that multiple parts of the project can remain within a more continuous environment.
The software combines its geotechnical modules within the same platform and maintains project information through a single project structure. Analysis and design can then continue into project drawings, quantity takeoffs, and reporting instead of ending with a numerical result.
That continuity becomes especially valuable when revisions occur. A change in the ground model, foundation system, or excavation design is not only an analysis issue; it may affect calculations, drawings, quantities, and the final report. The more fragmented the workflow is, the more places the engineering team has to revisit and verify.
For firms adding geotechnical projects to their existing civil engineering services, the practical question is therefore not simply, “How many analyses can this software perform?” A more useful question is:
“How much of the geotechnical project can we manage without breaking the engineering workflow into disconnected pieces?”
That is where an integrated geotechnical platform such as SETAF2018 differs from assembling a project around a collection of individual engineering tools.
What Civil Engineering Firms Should Consider Before Taking on Geotechnical Projects
While advanced bearing capacity and settlement analysis software streamlines complex subsurface calculations, software alone does not replace specialized geotechnical expertise. Reliable structural design begins with high-quality site investigations; no algorithm can overcome the “garbage in, garbage out” limitation of poor drilling or incomplete field testing. Furthermore, even though tools like SETAF2018 automate correlation derivations and multi-layer stress distributions, selecting the appropriate design parameters ($c’, \phi’, E’, S_u$) still demands sound engineering judgment and local site familiarity. Finally, civil engineering firms must ensure full compliance with regional codes and design standards. SETAF2018 directly supports this decision-making process by integrating built-in frameworks for TBDY 2018, Eurocode 7 (EN 1997) Design Approach 2, FHWA, and national excavation support regulations—verifying shallow footings, rigid inclusions, shoring walls, and slope stability against rigorous limit state requirements.
Civil Engineering Software vs. Geotechnical Engineering Software
Expanding from structural or general civil engineering into geotechnical project work can broaden the services an engineering firm provides, but software capability should not be confused with engineering capability.
Dedicated geotechnical engineering software can make complex calculations faster, connect different stages of a project, and reduce repetitive work. The responsibility for understanding the ground, selecting appropriate parameters, interpreting results, and deciding whether a design is appropriate still belongs to qualified engineers.
For firms considering this expansion, four points are particularly important.
Software Does Not Replace Geotechnical Expertise
Software can calculate bearing capacity, model an excavation support system, search for critical slip surfaces, or evaluate settlement. It cannot independently determine whether the assumptions behind those calculations adequately represent the site.
This distinction becomes more important as software becomes more capable. An all-in-one geotechnical platform such as SETAF2018 can bring site data, analysis, design, drawings, quantities, and reporting into one workflow, but integration does not eliminate the need for geotechnical knowledge.
The software should support engineering judgment, not substitute for it.
Site Investigation Quality Still Determines Analysis Quality
Every geotechnical model begins with an interpretation of the ground.
Borehole depth and distribution, soil and rock descriptions, groundwater observations, SPT or pressuremeter results, laboratory testing, and other investigation data determine how well the subsurface conditions are understood. A sophisticated analysis cannot compensate for site data that fails to represent the actual ground conditions.
In practical terms, better software does not remove the classic input problem: the reliability of the analysis remains dependent on the reliability and representativeness of the information used to construct the model.
This is also why the ability to incorporate boreholes, soil layers, groundwater conditions, SPT results, and MPM profiles into the project is useful—but the engineering team must still decide how those observations should be interpreted.
Soil Parameters Require Engineering Judgment
Geotechnical parameters are not simply numbers to be entered into empty fields.
Two engineers can review the same investigation data and still need to consider drainage conditions, stress history, variability between boreholes, groundwater, the relevant failure mechanism, and the type of analysis before determining which parameters appropriately represent the design condition.
Software can perform correlations and calculations once the necessary inputs are established. Selecting representative soil parameters and understanding their limitations remain engineering decisions.
This is one of the fundamental differences between operating geotechnical software and practicing geotechnical engineering.
Local Standards and Design Requirements Matter
The appropriate analysis method is only part of the design problem. Engineers must also consider the standards, safety factors, limit states, and regulatory requirements applicable to the project.
SETAF2018 incorporates several frameworks into its calculation and design environment, including Eurocode 7 (EN 1997), TBDY 2018, FHWA references, and the Turkish Regulation on Excavation Support Structures – Design and Application Principles.
For EN 1997-1 specifically, its documented workflows include requirements for shallow foundations, piles and rigid columns, excavation support structures, and slope stability. Excavation support designs use Design Approach 2, while the relevant partial safety factors and limit states are incorporated into the corresponding calculations.
The broader principle applies regardless of software: the tool must fit the engineering and regulatory context of the project, not the other way around.
Civil Engineering Software vs. Geotechnical Engineering Software
The boundary between civil engineering software and dedicated geotechnical software is not defined by whether the program contains a foundation module. The more useful distinction is what the software is designed to model.
General civil or structural software primarily starts with the structure: loads, members, materials, supports, and structural response. Geotechnical software starts with the ground and its interaction with the proposed engineering works: subsurface conditions, soil parameters, groundwater, field investigation data, foundations, excavations, slopes, and ground improvement.
The capabilities can overlap, particularly around foundations and soil–structure interaction, but their primary engineering purposes remain different.
| Capability | General Civil / Structural Software | Dedicated Geotechnical Software |
| Superstructure analysis | Core capability | Limited / not the primary purpose |
| Borehole modeling | Limited or unavailable | Core project input |
| Soil stratigraphy and profiles | Usually simplified | Detailed soil-layer modeling |
| SPT / field investigation data | Limited | Incorporated into geotechnical workflows |
| Settlement analysis | Basic or limited | Dedicated analysis |
| Foundation bearing capacity | Basic or dependent on external inputs | Dedicated shallow/deep foundation analysis |
| Liquefaction analysis | Usually limited or separate | Dedicated geotechnical analysis |
| Slope stability | Usually requires another tool | Dedicated analysis |
| Excavation support | Structural components may be modeled | Soil + support system analysis and design |
| Ground improvement | Generally outside core scope | Can be part of the geotechnical model and design |
| Geotechnical reporting | Limited | Project-specific engineering reporting |
This does not make one category of software more advanced than the other. They are built to solve different engineering problems.
For a structural engineering office that receives geotechnical parameters from another consultant, general structural software may be entirely appropriate. But once the same firm assumes responsibility for interpreting subsurface data, checking foundation performance, designing excavation support or ground improvement, evaluating stability, and producing geotechnical deliverables, the required software environment changes with the scope.
That is the point at which dedicated geotechnical software becomes more than an additional calculation tool. It becomes part of the infrastructure required to deliver the geotechnical side of the project properly.
Where SETAF2018 Fits into a Multidisciplinary Engineering Office
The value of SETAF2018 depends partly on how an engineering office is structured. A structural-focused firm beginning to undertake geotechnical work has different needs from an established geotechnical consultancy, while a multidisciplinary office has to coordinate expertise across both sides of the project.
What connects these cases is not a need to make structural and geotechnical engineering interchangeable. It is the need for a dedicated environment in which geotechnical work can move from project data to final deliverables without being unnecessarily divided across separate tools.
For Structural-Focused Civil Engineering Offices Expanding Their Scope
A civil engineering office may traditionally focus on superstructure design while receiving soil parameters, foundation recommendations, or geotechnical reports from other project stakeholders.
That workflow changes when the firm begins taking responsibility for parts of the geotechnical scope itself.
Foundation analysis may lead to settlement assessment. Ground conditions may require piles, micropiles, or ground improvement. A basement may introduce excavation support design. Those decisions then create their own requirements for calculations, drawings, quantities, and reporting.
SETAF2018 provides a dedicated all-in-one geotechnical software environment for this additional scope. Rather than building a new workflow around separate spreadsheets, calculation programs, CAD files, and reporting documents, the firm can manage much of the geotechnical project within a connected project structure.
Importantly, this expands the firm’s technical workflow, not the professional competence of the engineer operating it. The appropriate geotechnical expertise remains essential.
For Multidisciplinary Engineering Offices
Multidisciplinary firms face a different problem: the expertise may already exist internally, but project information still has to move between structural and geotechnical teams.
The interface between those teams is critical. Structural engineers establish the loads and structural requirements reaching the foundation system; geotechnical engineers evaluate how the ground and foundation system respond. Their work is separate, but their decisions are connected.
SETAF2018 can provide the geotechnical side of that workflow with a consistent environment for ground modeling, foundation and excavation-support analysis, design, drawings, quantities, and reporting. Its documented scope extends from geotechnical analysis and design through project drafting and quantity takeoff.
For the wider office, the benefit is a clearer handoff: structural information enters a dedicated geotechnical workflow, and the resulting foundation or ground-related design can return to the wider project as documented engineering output.
For Geotechnical Engineering Offices
For a specialist geotechnical office, the value proposition is different again. There is no need to expand into geotechnical engineering—the expertise is already there.
The opportunity is to reduce the number of disconnected steps required to turn that expertise into a completed project.
With SETAF2018, the workflow can continue from site investigation data and ground modeling through analysis and design to drawings, quantity takeoffs, and geotechnical reporting. The software supports foundation and excavation-support drawings in DWG format and quantity outputs in XLSX, while its reporting environment can combine calculations, design data, tables, graphs, images, and engineering commentary.
The goal here is not simply to perform more calculations in one program. It is to preserve continuity between the engineering work and the deliverables produced from it.
SETAF2018 is not about blurring the line between structural and geotechnical engineering. It is about reducing the fragmentation between the tools required to deliver a geotechnical project.
For a structural-focused office, that can mean a dedicated environment for a new geotechnical scope. For a multidisciplinary firm, it can mean a more structured interface between disciplines. And for a geotechnical consultancy, it can mean carrying existing expertise through a more comp
Frequently Asked Questions About Civil and Geotechnical Engineering Software
Can structural engineering software perform geotechnical analysis?
Structural engineering software can incorporate certain geotechnical inputs, such as foundation stiffness, soil springs, bearing assumptions, or simplified soil–structure interaction. However, these capabilities should not be confused with a complete geotechnical analysis workflow. Dedicated geotechnical software works with subsurface conditions, borehole and field-test data, soil parameters, groundwater, settlement, bearing capacity, stability, and other ground-related problems. The difference is therefore not simply whether the software can “model soil,” but how deeply the ground itself can be investigated and analyzed.
Do civil engineers need separate software for geotechnical design?
It depends on the firm’s project scope. A civil or structural engineering office that receives foundation parameters and geotechnical recommendations from another consultant may not need dedicated geotechnical design software. Once the firm becomes responsible for foundation performance, settlement, excavation support, ground improvement, slope stability, or similar work, dedicated software becomes much more relevant. An all-in-one geotechnical platform can also reduce the need to distribute calculations, drawings, quantities, and reports across several unrelated tools.
What software is used for foundation and soil analysis?
Foundation and soil analysis typically requires dedicated geotechnical engineering software capable of representing subsurface conditions rather than treating the ground only as a structural support. Depending on the project, the required capabilities may include bearing capacity, settlement, piles and micropiles, soil improvement, excavation support, slope stability, and liquefaction analysis. SETAF2018 combines these capabilities with ground modeling, design, drafting, quantity takeoff, and reporting, positioning it as an all-in-one geotechnical software rather than a standalone foundation calculator.
Can one software handle foundation, slope stability, and excavation support analysis?
Yes, provided the platform is designed as a broader geotechnical engineering environment rather than a single-purpose analysis tool. SETAF2018 supports shallow and deep foundation systems, slope and embankment stability, and excavation support systems including bored pile walls, anchors, soil nails, and reinforced concrete retaining walls. Bringing these analyses into the same environment is particularly useful when several geotechnical problems occur within the same project and depend on a common understanding of the site’s ground conditions.
Does geotechnical software replace a geotechnical engineer?
No. Geotechnical software performs calculations and helps engineers model, analyze, design, document, and report a project, but it does not replace geotechnical expertise or engineering judgment. Site investigation data must still be interpreted, representative soil parameters must be selected, appropriate analysis methods must be chosen, and results must be evaluated in their engineering context. More capable software can improve the workflow; it does not transfer professional responsibility from the engineer to the program.
Can civil engineering firms expand into geotechnical design services?
Yes, but expanding the firm’s service scope requires more than adding geotechnical software. The firm needs the appropriate geotechnical expertise, reliable site investigation data, applicable professional authorization, suitable design procedures, and a workflow capable of producing the required engineering deliverables. For firms that already have or bring in that expertise, an all-in-one platform such as SETAF2018 can provide the technical environment for moving from ground data → analysis → design → drawings → quantities → geotechnical reporting without building that workflow around a collection of disconnected tools.
