Five ways Nudura is changing the way homes are designed and built:

🔹 Up to 58% more energy efficient than traditional builds
🔹 Withstand winds up to 250 mph
🔹 4-hour fire rating (vs. 45 minutes with wood framing)
🔹 Install 25–50% faster
🔹 Reduce callbacks, waste, and freight costs

And that’s just scratching the surface.

ICFs create wins for homeowners, contractors, architects AND distributors — and Nudura leads the way with innovations like Duramax®, Durafold®, and our 4-Way Reversible System.

Cost Of Construction Project

Materials (55-60%): This is the largest portion of the cost, covering the purchase of all building materials such as cement, steel, bricks, etc.

Labour (25-30%): This includes the cost of hiring workers and paying for their labor throughout the construction process.

Professional Fees (5-10%): These costs cover the payments for architects, engineers, consultants, and other professionals involved in the planning, design, and oversight of the project.

Contractor Profit (5-10%): This is the profit margin that the contractor earns from executing the construction work.

Safety (5%): This expense is dedicated to ensuring that the construction site meets safety standards and that workers have the necessary protective equipment and safety measures.

Permissions & Legal (2-5%): These are the costs related to obtaining the necessary permits, legal approvals, and regulatory compliance.

Contingencies (5-10%): This is a reserved fund to cover any unforeseen circumstances or issues that may arise during the construction, such as material shortages or design changes.

Lam Sum (2%): This could refer to a lump sum fee, a fixed cost that is included as part of the overall budget, covering a variety of items not specified in the breakdown.

The percentage of construction cost attributed to each phase or element can vary depending on factors like the type of building, location, design, and materials used. However, here’s a general breakdown of the typical percentage allocation of construction costs for various elements:

1. Groundwork – 10-15%

Description: This includes the preparation of the site, excavation, foundation work, drainage, and soil testing. Groundwork is essential for ensuring the stability of the structure and is typically one of the first steps in any construction project.

Cost Factors: Site conditions, soil type, foundation type, and the complexity of excavation.

2. Roof – 5-10%

Description: The cost for constructing the roof includes framing, sheathing, waterproofing, insulation, and roofing materials (e.g., tiles, shingles, metal). The roof is critical for protecting the structure from the elements.

Cost Factors: Roof type (flat, pitched, etc.), material selection, and insulation requirements.

3. Structure – 25-30%

Description: This category includes the foundation, structural framework (columns, beams, slabs), and reinforcements. It provides the essential support for the building.

Cost Factors: Material choice (concrete, steel, wood), building design (high-rise or low-rise), and complexity of structural elements.

4. Plastering – 4-6%

Description: Plastering involves the application of plaster to internal and external walls and ceilings. It provides a smooth surface for painting and adds to the building’s durability.

Cost Factors: Type of plaster (cement-based, gypsum), surface preparation, and the area to be covered.

5. Plumbing – 5-10%

Description: Plumbing costs include the installation of water supply and drainage systems, pipes, fittings, and fixtures (toilets, sinks, showers, etc.).

Cost Factors: Pipe material (PVC, copper), the number of fixtures, complexity of plumbing (multi-story buildings), and location.

6. Electrical – 5-10%

Description: The electrical system covers the wiring, outlets, switches, circuit breakers, lighting fixtures, and connection to the grid.

Cost Factors: Type of electrical fittings, load requirements, complexity (smart systems, security), and code requirements.

7. Landscape – 3-5%

Description: Landscaping includes the design and construction of outdoor areas such as gardens, pathways, lawns, outdoor lighting, and irrigation systems.

Cost Factors: Type of landscaping (softscape vs. hardscape), plant choices, and features like patios or retaining walls.

Notes:

Building Complexity: For larger or more complex buildings (like high-rises), structural and electrical costs might be higher, while smaller buildings may have lower costs in these areas.

Material Choices: Premium materials for roofing, plumbing, or finishes (like luxury flooring or smart home electrical systems) can significantly increase costs in specific areas.

Location: Labor costs, material availability, and local codes/regulations can also influence the cost allocation percentages.

Project Type: Commercial buildings or specialized structures (e.g., hospitals, factories) might have different cost distributions due to unique requirements in each phase (e.g., specialized plumbing or electrical systems).

This breakdown can be adjusted depending on the specifics of the construction project.
