Before execution, the design must be validated for constructability — ensuring it can be built safely, efficiently, and economically.

1. Constructability Review

Systematic evaluation of design documents from a builder’s perspective.

Checklist Includes:

• Are the details feasible with available construction methods?
• Are material specifications practical and locally available?
• Do drawings reflect site constraints accurately?
• Are safety and maintenance provisions considered?
• Is there potential for modularization or prefabrication?

Participants: Design engineers, construction managers, procurement heads, and safety officers.

2. Value Engineering (VE)

Value Engineering seeks to maximize value by optimizing cost, quality, and performance.

Value= Function / Cost

Steps in the VE Process:

• Information Phase – Understand project goals and design intent.
• Function Analysis Phase – Identify key functions of components.
• Creative Phase – Brainstorm alternative methods or materials.
• Evaluation Phase – Compare alternatives based on feasibility and ROI.
• Implementation Phase – Approve and integrate selected alternatives.
  

Example:

Replacing traditional scaffolding with modular systems → 30% faster erection, 20% lower labor cost.
