In technical planning for construction projects, which actions are core objectives to ensure readiness and smooth execution?

Introduction / Context:
Technical planning bridges design intent and site execution. It ensures that scope is clear, costs are forecast, materials and services are secured on time, and probable constraints are addressed proactively. The question checks a holistic view of planning deliverables.

Given Data / Assumptions:

• Specifications capture quality and methods.
• Estimates quantify costs from quantities and rates.
• Procurement lead times affect schedule.
• Bottlenecks require early mitigation.

Concept / Approach:
Planning is not only documentation but also orchestration of resources and risk controls. Specifications and estimates set the baseline; procurement aligns suppliers with the schedule; risk actions remove or reduce anticipated blockers to maintain flow during execution.

Step-by-Step Solution:
Confirm specifications are prepared to define scope and quality.Confirm estimates are produced to budget work packages.Initiate procurement so materials, equipment, and subcontracts are available when needed.Plan remedial actions for predictable bottlenecks such as permits, utilities, and access constraints.Therefore, all options are integral to technical planning.

Verification / Alternative check:
Project management guides list scope definition, cost estimation, procurement planning, and risk response planning as core planning processes.

Why Other Options Are Wrong:

• Picking any subset omits essential planning elements.

Common Pitfalls:
Treating planning as only paperwork; delaying procurement until site is mobilised; ignoring predictable risks until they become issues.

Final Answer:
All the above.
