Model Contract Document for Maintenance of Highways

IRC SP 95: Scope - Key Specifications & Tables

The Scope defines the extent and components of highway maintenance works covered under the contract, guiding bidders on asset quantities and types.

Key Components & Approximate Quantities (Clause 1.6)

Important Notes:

• Quantities are approximate; bidders must verify on-site per Clause 1.6.
• Scope includes all assets relevant to the highway section.
• Read in conjunction with Volume 2 Section VI Part-B for supplementary specs.

Summary Table Example (for Bidder's Guidance)

IRC SP 95 does not explicitly provide detailed formulas or tables for Source of Funds or Eligible Bidders. However, based on standard bidding and procurement practices, here are key points:

Source of Funds

• Typically refers to the financial backing for the project (e.g., government budget, loans, grants).
• Must be clearly identified in tender documents.
• Ensures transparency and financial capability to complete the project.

Eligible Bidders

• Must meet prequalification criteria such as:
  • Financial capacity (minimum turnover, net worth)
  • Technical experience (similar completed projects)
  • Legal status (registration, licenses)
• Bidders must submit proof of funds or bank guarantees.
• Compliance with local laws and IRC guidelines.

Typical Qualification Metrics (Example):

    B --> C[Bid Document Prepared]
    C --> D[Eligibility Criteria Defined]
    D --> E[Bidder Qualification Check]
    E --> F[Eligible Bidders Shortlisted]

Summary: IRC SP 95 treats "Bid" and "Tender" synonymously but does not specify formulas or tables for funds or eligibility. Use standard procurement norms for these aspects.

IRC SP 95: Bidding Documents & Instructions to Bidders - Key Points

IRC SP 95: Qualification and Bid Evaluation

IRC SP 95 focuses on selecting the lowest evaluated tender after post-qualification of bidders. It does not provide explicit formulas but outlines a procedural framework:

Key Points:

• Qualification Information Forms: Collect bidder's financial, technical, and past experience data.
• Bid Forms: Standardized formats for price and technical offers.
• Bid Evaluation:
  • Evaluate bids based on lowest evaluated cost.
  • Post-qualification verifies bidder's capability (financial strength, experience, resources).
• Pre-qualification: If done, adjust the process accordingly.

Typical Bid Evaluation Criteria (General Practice):

Formula for Evaluated Bid Price:

[ \text{Evaluated Price} = \text{Bid Price} + \text{Cost of Deviations/Adjustments} ]

Simplified Bid Evaluation Flowchart:

Defects Liability Period (DLP) & Defect Rectification - IRC SP 95 Key Points

• Applicability:

• Duration & Extension (Clause 31.2):

  • DLP starts from the "Taking Over" certificate date.
  • If defects appear during DLP, the Engineer notifies the Contractor before DLP ends.
  • DLP is extended until all defects are rectified.

• Defect Testing (Clause 30.2):
