iSAT Network Engineers Design Substations 40% Faster with the Bentley Substation Solution - 1

CASE STUDY Project Summary Organization: iSAT Network Engineers Pvt. Ltd. Solution: Utility Transmission and Distribution Infrastructure Location: Dehradun, Uttarakhand, India Project Objective: • Develop a 132-kilovolt substation with a total capacity of 80 million volt-amperes. • Design for safety and system reliability to withstand extreme weather conditions and in compliance with India’s earthquake-resistant design code. • Minimize construction change orders, project arbitrations, and delays to stay on schedule. Products used: Bentley Substation, MicroStation®, STAAD.Pro, Structural Synchronizer Fast Facts • iSAT chose Bentley’s substation solution to accelerate design and improve constructability by enabling simultaneous structural, electrical, and physical design. • Bentley’s Structural Synchronizer enabled team members to minimize errors by sharing structural models between STAAD.Pro and Bentley Substation. ROI • Creating intelligent 3D models reduced the number of revisions required to arrive at final plans by 60 percent. • Bentley’s substation solution reduced the time required to arrive at the final plans by 40 percent. • iSAT saved approximately 20 man-days in the process of completing the design and quantity estimation. iSAT Network Engineers Design Substations 40% Faster with the Bentley Substation Solution Integrated Design Solution Increases Cross-discipline Collaboration to Reduce Design Revisions and Costly Construction Change Orders Accelerating Projects with Intelligent Design iSAT Network Engineers is a fast-growing engineering/ procurement/construction company that provides turnkey solutions for utility transmission and distribution as well as high-power testing labs. Power Transmission Corporation of Uttarakhand retained iSAT to develop a 132-kilovolt substation with a total capacity of 80 million volt-amperes in the capital city of Dehradun, Uttarakhand, India. iSAT employed a new approach for the INR 114.4 million project that unified physical, electrical, and structural substation design with Bentley’s integrated applications. The Bentley substation solution enabled the use of intelligent models that increased cross-discipline collaboration, reduced revisions by 60 percent, improved the quality of cost estimates, and accelerated the overall design process by 40 percent. iSAT integrated 2D electrical design, 3D physical layout, and structural design using Bentley Substation and STAAD.Pro. typically numerous and expensive change orders, project arbitrations, and delays. “To successfully design this project we needed a comprehensive solution that would simultaneously help in electrical design and substation structural design.” — Manoj Pal, senior manager for project & service, iSAT Network Engineers Traditional Design Process Hindered Efficiency “Traditionally, designs for substations in India were being produced as 2D plans without having any built-in intelligence. This made the design process complex, often requiring numerous revisions before arriving at the final plans,” said Manoj Pal, senior manager for project & service, iSAT Network Engineers. The degree of complexity made it difficult to visualize the designs and impaired the project team’s ability to check clearances, detect clashes, and resolve interferences. The 2D design approach also made generating bills of materials a time-consuming and error-prone manual task that often took hours or days. As a result, when plans were implemented at the construction site, there were The traditional structural design process was also inefficient, with disconnected workflows requiring manual paper-based coordination with the electrical and physical substation designs. These inefficiencies would be a particular problem on the Dehradun substation project in which iSAT faced the task of designing the substation to operate safely and efficiently in an earthquake-prone region, where equipment support structures and foundations must comply with India’s earthquake-resistant design code (IS 1893). Moreover, the structures would experience additional loads from hostile weather such as high winds and extreme precipitation. “To successfully design this project we needed a comprehensive solution that would simultaneously help in electrical design and substation structural design,” said Pal. iSAT Opts for an Integrated Design Solution To overcome the challenges associated its traditional substation design approach and enable concurrent and coordinated cross-discipline design, iSAT chose to use a portion of the Bentley substation solution: an integrated set of Bentley software applications that accelerate design, improve constructability, and reduce the operating costs of electric substations.

“The 3D substation models were used to detect clashes and interferences before the designs were signed off. This reduced the number of revisions required to arrive at final plans by 60 percent.” — Manoj Pal, senior manager for project & service, iSAT Network Engineers.
