Subhead 0.0: General

0.1 References

• References in this section apply to all sections unless context dictates otherwise. They supplement the provisions in each specific section. In case of any discrepancy, the provisions in the specific section take precedence.

Example: If there is a contradiction between the general guidelines for concrete mixing in Section 0.0 and the specific guidelines in Section 4.0, the latter will be followed.

0.2 Rates

• The rates for all items of work include the cost of all labor, materials, and other inputs involved in the execution, unless specified otherwise.

Example: If a contractor is quoted for bricklaying, the rate will include the costs of bricks, mortar, labor, and necessary tools, unless stated otherwise.

0.3 Interpretations

• The Director General (Works), CPWD, is the sole authority for interpreting the specifications. His decision is final.

Example: If there is a disagreement over the interpretation of the required curing period for concrete, the decision of the Director General (Works) will be binding.

0.4 Definitions

• Contractor: Refers to the individual, firm, or company undertaking the works, including their legal representatives or assignees.
• Engineer-in-Charge: The Engineer officer supervising the work and signing the contract on behalf of the President.
• Site: The land or places where the work is executed, including adjacent land or paths used for the project.
• Store: The place of issue of materials as per the schedule of the contract. This may include any CPWD store in the district.
• IS: Standards issued by the Bureau of Indian Standards (BIS).

Example: The term "Contractor" includes a construction firm working on a government project and their successors who take over the project.

0.5 Measurement of Works

• Measurements will be taken as per standard methods unless specified. This ensures consistency and accuracy in recording the work done.

Example: Measurement of a plastered wall will follow the sequence of length, width, and height, and the values will be recorded to the nearest centimeter.

0.6 Foundations and Plinth

• Specifications for foundations and plinths include guidelines for buildings, abutments, piers, retaining walls, and reservoirs. Work is typically considered up to 1.2 meters above ground level.

Example: For a residential building, all foundation work up to the plinth level (1.2 meters) will follow these guidelines.

0.7 Rounding Off Measurements

• Measurements should be rounded off according to IS: 2-1960 standards. The number of significant places for rounding is specified.

Example: If the calculated length of a beam is 1.256 meters, it will be rounded to 1.26 meters as per the guidelines.

0.8 Materials

• Approval: Samples of all materials must be approved by the Engineer-in-Charge. Approved samples are kept until the project completion.
• Testing: Materials from approved sources are subject to mandatory tests. Non-conforming materials will be addressed by the Engineer-in-Charge.
• Costs: The contractor bears the cost of providing samples and incidental expenses for testing, except for testing charges.
• Storage: Materials must be stored properly to avoid deterioration due to atmospheric conditions.
• Safety: Inflammable materials must be stored safely as per regulations.

Example: A sample of cement will be tested for quality, and only if it passes, it will be used for construction. The contractor is responsible for any costs related to obtaining and testing the sample.

0.9 Safety in Construction

• The contractor must employ safe construction methods and is responsible for worker safety. Safety precautions must follow CPWD codes and the directions of the Engineer-in-Charge.

Example: Safety measures include proper scaffolding, secure electrical connections, and precautions during welding operations.

0.10 Abbreviations

• The document includes a list of common abbreviations used in the specifications.

Example: "RCC" stands for Reinforced Cement Concrete, and "IS" refers to Indian Standards.

These general guidelines ensure a standardized approach to construction practices across various projects, providing clarity and consistency in interpretation, execution, and quality assurance.
