OVER-DESIGN vs UNDER-DESIGN

Which one is really draining your project budget?

The Client’s Assumption

Many clients believe:

➡️ “If it’s over-designed, it must be safer.”

➡️ “If it cracks, it must be under-designed.”

⚠️ Both assumptions are incomplete — and expensive.

What Is Over-Design?

Over-Design occurs when structural elements are:

• Heavier than required
• Excessively reinforced
• Designed with unrealistic safety margins

Hidden cost:

💸 Higher material cost

⏱ Longer construction time

🏗 Bigger foundations & columns

🔧 Difficult future modifications

What Is Under-Design?

Under-Design happens when elements lack sufficient capacity for:

• Actual loads
• Durability demands
• Serviceability requirements

Consequences:

⚠️ Excessive cracks & deflections

⚠️ Progressive deterioration

⚠️ Safety risks

⚠️ Costly repairs or failure

The Real Cost Comparison

Issue   Over-Design   Under-Design

Initial cost       ❌ Too high    ✅ Appears cheaper

Long-term cost            ⚠️ Inefficient ❌ Very high

Safety ⚠️ Brittle risk ❌ Failure risk

Client value    ❌ Wasted capital     ❌ Asset at risk

👉 Both fail the client in different ways.

The Engineering Truth

Good engineering is NOT about:

❌ Maximum steel

❌ Minimum steel

It is about:

✅ OPTIMUM DESIGN

✅ Code-compliant

✅ Economical

✅ Safe

✅ Serviceable

✅ Durable

Why This Happens in Practice

Common root causes:

• Poor load estimation
• Material uncertainty
• Fear-based design decisions
• Lack of independent design review
• Inadequate value engineering

How ABAMATH Solves This:

At ABAMATH GLOBAL COMPANY LIMITED, we:

✔ Balance safety with economy

✔ Apply limit state & serviceability checks

✔ Account for material variability

✔ Perform independent design audits

✔ Protect client capital without compromising safety

Call to Action

Planning or reviewing a high-rise project?

📩 Let ABAMATH audit your design before construction begins.

Many clients think “more steel means more safety”.

Others assume cracks automatically mean bad design.

The truth?

Both over-design and under-design can fail a project — just in different ways.

Over-design silently drains capital through unnecessary materials and construction complexity.

Under-design exposes occupants and investors to long-term safety and financial risks.

At ABAMATH GLOBAL COMPANY LIMITED, we focus on OPTIMAL structural design — where safety, economy, and durability are balanced using sound engineering principles.

If you’re investing in or managing a high-rise building, the right question is not “Is it heavy enough?”

👉 The right question is: Is it optimally designed?
