This government tender offers a unique opportunity for experienced structural engineering firms to conduct a comprehensive assessment of a bridge in Valsad, Gujarat. The project involves advanced instrumentation, vibration analysis, and 3D Finite Element Analysis to evaluate the structural integrity of the bridge. Bidders will perform field measurements over three days, analyze data, and prepare a detailed Structural Adequacy Report. The project aims to enhance infrastructure safety, support maintenance planning, and ensure compliance with safety standards. With a project duration of 12 months and a budget of approximately INR 5 lakh, this tender is ideal for organizations with expertise in bridge health monitoring, instrumentation, and FEA modeling. The process is fully electronic, requiring bidders to submit technical and financial proposals via the NPROCURE portal. Don't miss this opportunity to contribute to vital infrastructure safety in Gujarat.

Scope Of Work

The selected service provider shall execute the following tasks:

  • Conduct three consecutive days of detailed field instrumentation at the specified bridge site.
  • Use Triaxial Accelerometers to measure vibration levels of the bridge superstructure.
  • Employ Liner Displacement Transducers (LVDT) to monitor movement at expansion joints.
  • Measure deflection at mid-span using Laser Sensors.
  • Collect all field data meticulously and ensure calibration of instruments.
  • Analyze the collected data to assess the structural health.
  • Prepare a comprehensive Structural Adequacy Report based on field results.
  • Perform 3D Finite Element Analysis (FEA) modeling using MIDAS/SOFISTIK software.
  • Provide recommendations for maintenance or necessary reinforcements.
Key Deliverables Specifications
Instrumentation Setup Triaxial Accelerometers, LVDT, Laser Sensors
Data Collection Vibration, displacement, deflection data
Structural Analysis 3D FEA modeling in MIDAS/SOFISTIK
Final Report Structural adequacy and safety report

The contractor must ensure compliance with all safety standards and provide detailed documentation of all procedures and results.

Technical Specifications

The instrumentation used must adhere to industry standards, with calibration certificates issued within the last 12 months. The vibration sensors should have a frequency response suitable for bridge assessment, typically from 0.1 Hz to 1000 Hz. Displacement sensors must have a minimum resolution of 0.01 mm. Data acquisition systems should support real-time data logging and synchronization across all sensors. The FEA software must support nonlinear dynamic analysis with material and geometric nonlinearities. The process involves sequentially:

  1. Setting up instrumentation at designated locations.
  2. Conducting field measurements over three days.
  3. Analyzing data for anomalies.
  4. Developing detailed FEA models.
  5. Validating models with field data.
  6. Generating final reports with recommendations.

Financial Requirements

The estimated budget for this project is approximately INR 5,00,000, covering instrumentation, data analysis, report preparation, and software modeling. The breakdown is as follows:

Cost Component Estimated Cost (INR)
Instrumentation & Setup 2,00,000
Data Analysis & Reporting 1,50,000
FEA Modeling 1,00,000
Miscellaneous & Contingencies 50,000

Payment will be made in installments:

  • 30% upon contract signing.
  • 40% after completion of field data collection.
  • 30% after submission and approval of the final report.
    All payments are subject to submission of valid invoices and progress reports.
