Planning and Design

Project planning defines four interdependent elements:

• Scope
• Diagrams
• Budget
• Schedule

Each communicates the project differently:

• Scope = written definition
• Diagrams = visual translation
• Budget = financial boundaries
• Schedule = time sequencing

These must work together.

When one changes, the others adjust.

Planning is iterative.

CIY guides you through building each element deliberately — not informally.

A coordinated plan is required before requesting pricing.

Incomplete planning produces pricing variability.

Develop the Plan Before Bidding

Follow the Planning Phase in sequence before entering Bidding.

Clear documentation improves:

• Bid accuracy
• Contractor comparison
• Construction control

Diagrams are not optional illustrations.

They are the visual contract of intent.

They reduce assumptions.
They reduce interpretation.
They reduce pricing volatility.

Interpretation increases cost.

Undefined expectations invite variability.

CIY’s Planning tools guide you step-by-step in translating your vision into documents that contractors can price consistently.

Clarity first.
Then pricing.

How Much Design Is Required?

The level of professional design depends on:

• Project size
• Structural impact
• Systems changes
• Local requirements

Architects produce coordinated construction drawings.

Interior Designers shape layout and finishes.

Engineers design structural, mechanical, electrical, and plumbing systems.

If structure or major systems are modified, licensed design may be required.

Even when professional design is used, owner clarity still matters.

Contractors price, what is defined.

Undefined expectations create pricing variability.

CIY prepares you to communicate clearly with design professionals before drawings are finalized.

Design Costs

Architectural design typically ranges from 4%–7% of construction cost.

Engineering services typically range from 1.5%–3%.

Smaller projects often carry higher proportional design costs.

Engineering is frequently coordinated through the architect to maintain document consistency.

Cost is visible.

Coordination gaps are not.

Do You Need Professional Design?

In many residential projects, owners act as the primary designer.

That is workable — if scope and diagrams are clearly documented.

For additions, new construction, or structural modifications, stamped drawings are often required.

Even when not required, complexity benefits from professional oversight.

Early consultation reduces redesign risk during construction.

💡 TIP: Architects and interior designers shape how buildings look and feel.
Engineers design how buildings function.

💡 TIP: If professional services are required, review 🔒 Planning – Create the Project Diagrams to understand how design intent becomes construction documentation.

What Comes Next

Planning establishes scope clarity and visual intent.

Permitting establishes what must be formally approved before work begins.

Understanding the permit process clarifies how your scope and diagrams become authorized construction.
