In engineering documentation, drawings and specifications typically govern design, materials, fabrication, and installation; they usually do not prescribe ongoing maintenance procedures, which are handled by operation and maintenance manuals. Is this statement correct?

Introduction / Context:
Project documentation is divided by purpose. Construction drawings and specifications define what will be built and how to build it. Operation and maintenance (O&M) manuals and asset management plans define how to service and maintain the finished asset. The statement claims drawings/specifications typically do not control maintenance details. We assess this claim.

Given Data / Assumptions:

• Deliverables include drawings, specifications, and separate O&M documents.
• Industry practices from building, plant, and product development are comparable.
• “Control details” means procedural direction for recurring maintenance tasks.

Concept / Approach:
Drawings/specs: geometry, materials, tolerances, performance criteria, installation, and testing during handover. Maintenance: lubrication intervals, inspection checklists, replacement parts, calibration frequency, and troubleshooting—typically provided in O&M manuals/vendor literature.

Step-by-Step Solution:
1) Identify scope of drawings/specs: define asset to be constructed.2) Identify scope of O&M: define post-handover operations and care.3) Note exceptions: specs may reference maintenance requirements but seldom provide step-by-step procedures.4) Conclude that detailed maintenance control is not the primary function of drawings/specs.

Verification / Alternative check:
Standard contract structures (e.g., in construction) separate design/specification packages from O&M deliverables; commissioning closeout lists manuals as distinct artifacts.

Why Other Options Are Wrong:
“Incorrect”: Misstates typical document roles.“They fully define preventive maintenance schedules”: That belongs to O&M, not drawings/specs.“They only cover warranty clauses”: Specifications do far more than warranty language.

Common Pitfalls:
Expecting shop drawings to serve as maintenance guides; ignoring vendor manuals; burying maintenance notes in general notes where they can be missed.

Final Answer:
Correct
