Bentley Systems’ SPIDAcalc and SPIDAsilk are purpose-built solutions that streamline the analysis, design, and management of overhead electric and communication networks.
If your organization needs precise analysis, compliance-ready reporting, and seamless workflow integration—SPIDAcalc and SPIDAsilk should be on your radar. In this article we’re diving into what each product does, who it’s for, and how both can work together to elevate your infrastructure design and analysis process.
SPIDAcalc Explained
SPIDAcalc is Bentley’s dedicated software for modeling, analyzing, and optimizing overhead electric distribution systems. It provides utility and engineering teams with a modern, intuitive interface and a robust analysis engine that delivers dependable results.
Key Capabilities of SPIDAcalc
- Advanced system modeling & Design Tools
SPIDAcalc provides a configurable drag-and-drop interface with both 2D and 3D views, allowing engineers to quickly model single-pole overhead electric and telecommunications systems. - Powerful geometric non-linear analysis
The software uses a finite element analysis engine to model pole loading, clearances, remaining strength, and stress factors – helping reduce safety and reliability risks. - Prebuilt safety compliance standards
Out-of-the-box support for NESC, CSA, and GO95 to make compliance easier and automated. - Automated clearance evaluation
Design layers and comparison tools enable efficient “make-ready” statements and above-ground clearance assessments.
Who Benefits from SPIDAcalc?
- Electric utilities
- Telecommunications and broadband providers
- Engineering firms and construction contractors
- Joint-use contractors
SPIDAcalc streamlines workflows, from data collection to design, to final deliverables, making it ideal for optimizing both existing assets and new construction
SPIDAsilk Explained
SPIDAsilk is Bentley’s conductor sag and tension analysis software, built to deliver precise sag-tension tables and stringing charts for electric and telecom applications.
Key Capabilities of SPIDAsilk
- Accurate nonlinear sag & tension calculations
SPIDAsilk uses precise numerical algorithms to model catenary geometry, producing detailed sag‑tension reports for multiple weather cases and design scenarios. - Excel-based reporting for convenience
Users can quickly access formatted stringing reports and sag‑tension tables—no more manual calculations or outdated lookup tables. - Communication bundle modeling
Define communication bundles, overlashing, and even model 5G antennas, marker balls, and other span-mounted equipment anywhere along the span. - Built-in sag and tension design constraints
Set limits based on sag, tension, or percent of rated tensile strength to meet any custom or code‑based design requirement. - Seamless integration with SPIDAcalc
SPIDAsilk shares wire tension methods with SPIDAcalc to ensure consistency across platforms and simplify the engineering workflow.
Who benefits from SPIDAsilk?
- Electric transmission & distribution engineers
- Telecommunications providers
- Utility consultants
- Overhead design specialists
SPIDAsilk is an affordable, easy‑to‑use platform ideal for both new line design and the evaluation of complex spans, bundles, and special equipment loads.
How SPIDAcalc & SPIDAsilk Work Together
While SPIDAcalc focuses on system‑level modeling of poles and overhead assets, SPIDAsilk specializes in conductor‑level sag and tension behavior. Together, they provide a complete ecosystem for accurate overhead design and analysis.
Combined benefits include:
- Unified engineering workflow
- Consistent wire tension methods
- Reduced design errors and redundancies
- Faster preparation of construction‑ready documentation
Engineers can move seamlessly between pole loading analysis (SPIDAcalc) and detailed conductor modeling (SPIDAsilk), ensuring all aspects of the overhead system are accurately represented.
Why Utilities Are Standardizing on Bentley’s SPIDA Tools
Utilities and telecom companies face growing pressures—aging infrastructure, grid modernization, increasing broadband deployments, and stricter safety standards. Tools like SPIDAcalc and SPIDAsilk help address these challenges by delivering:
- Greater accuracy
- Improved compliance
- Better asset lifecycle decisions
- Reduced project delays and rework
- Streamlined joint‑use and make‑ready processes
Conclusion
Bentley’s SPIDAcalc and SPIDAsilk offer unmatched value for organizations that design, maintain, or optimize overhead electric and telecom networks. From detailed sag and tension analysis to system‑level modeling and compliance checking, these tools simplify complex engineering tasks while improving accuracy and safety.
