drawing tender Interview Questions and Answers

1. What is a drawing tender?

   • Answer: A drawing tender is a formal invitation to contractors to submit bids for a construction project based on detailed drawings and specifications. It differs from a design-and-build tender where the contractor also designs the project.

2. What are the key documents included in a drawing tender package?

   • Answer: A typical package includes drawings (architectural, structural, MEP), specifications, bill of quantities, tender instructions, contract conditions, and any other relevant documents such as site investigation reports.

3. Explain the importance of clear and accurate drawings in a tender.

   • Answer: Clear and accurate drawings are crucial for accurate costing by contractors, ensuring consistent interpretation of the design, and avoiding costly errors during construction. Ambiguous drawings lead to disputes and delays.

4. How do you ensure the completeness of drawings before issuing a tender?

   • Answer: A thorough internal review process involving all relevant disciplines (architecture, structural, MEP, etc.) is vital. Checklists and design reviews help identify omissions and inconsistencies before the tender goes out.

5. What are the potential risks associated with incomplete or inaccurate drawings?

   • Answer: Risks include inaccurate cost estimations, delays, disputes between the client and contractor, rework, increased project costs, and potential safety hazards.

6. Describe the process of preparing a drawing tender.

   • Answer: This involves preparing detailed drawings and specifications, creating a bill of quantities, developing tender documents (instructions, conditions), advertising the tender, receiving bids, evaluating bids, and selecting a contractor.

7. What is a bill of quantities (BOQ)? What is its role in a drawing tender?

   • Answer: A BOQ is a detailed list of all the materials and labor required for a project. In a drawing tender, it provides a structured framework for contractors to price their bids accurately and facilitates comparison between different tenders.

8. How do you handle discrepancies between drawings and specifications?

   • Answer: Resolve discrepancies by consulting with the design team. Usually, specifications take precedence over drawings if there's a conflict, but this should be clearly defined in the tender documents.
