Your Vision, Our Expertise: Tailoring Construction Costs to Your Unique Project

Embarking on a construction project can be a journey filled with excitement and anticipation. However, understanding the financial aspect of building your dream project is crucial. We recognize that every construction project is unique, and that's why we emphasize personalized cost estimation to reflect the true scope and nature of your undertaking.

​

Estimates vs. Reality: Navigating the Costs

Our published construction costs are estimates based on general conditions. It's important to note that costs can vary significantly depending on the location. For instance, construction in California generally incurs higher expenses compared to states like Georgia or Oklahoma. To provide you with the most accurate cost assessment, we delve deep into the specifics of your building site. Factors such as location, excavation requirements, electrical hookups, septic systems, and water access are crucial in shaping the final cost.

​

Customization and Precision in Planning

Once we have a comprehensive understanding of your site and construction needs, we can develop a detailed plan and permit strategy. This approach allows us to estimate precise costs tailored to your custom project. Our expertise extends to coordinating with local construction support, ensuring that every aspect of your project aligns with regional standards and practices.

​

Diverse Design Options and Their Impacts on Cost

We offer a variety of design options to suit your taste and functional requirements. Whether you prefer flat, sloped, or domed ceilings, we have solutions that cater to your preferences. Our domed ceiling designs, for example, allow for spacious rooms of 24'x24' and 28'x28' without the need for structural columns. This design not only provides aesthetic appeal but also enhances spatial efficiency. Remember, the choices in insulation, waterproofing, drainage, and backfill will influence your budget, and these costs are estimated separately after finalizing your plan and material selections.

​

​

Embark on Your Construction Journey with Confidence

Your vision deserves a foundation built on precision, customization, and understanding. Let us guide you through the complexities of construction costs, turning your dream project into a tangible reality. 

 

Typically a 30% deposit of the proposed total basic concrete construction holds your place on our traveling crews construction list with a scheduled construction date and is applied to the final pours of your project. Full payment for each poured section is due within 3 days of completion or as defined by contractural agreed terms prior to construction.

​

​

* NOTE: All published prices are based on $100 per yard concrete cost, $650 per ton on steel and $80 hourly for pump truck fees. In some locations these costs are more. When local costs exceed these amounts, it is the responsibility of the owner building their project to pay for these additional costs.

​

Any deviations in basic module and additions during construction are priced separately at a labor rate of $65 per hour. Prices are based on Steel Rebar prices at $650 per ton. Additional costs may apply.

​

CONSTRUCTION TIME: Usually it takes two to three weeks to set up and pour each 600 to 1000 square foot of space including all exterior walls  and all door and window openings and electrical and plumbing conduit. This is typically faster than traditional framing systems. Then we consult as needed as your local contractor finishes your project to your plan and permitting specifications.

​

PLANNING, ENGINEERING PERMITTING TIME: IT USUALLY TAKES 6 MONTHS OR MORE TO PLAN, ENGINEER & PERMIT A PROJECT due to the often long waits for permit processing.
