# Disclaimer
**Last Updated: 23 August 2026**
The information, calculators, formulas, guides, estimates and other materials available on **5iBuild** at **https://5ibuild.5itech.in/** are provided for general informational, educational and preliminary estimating purposes.
By using this website, you acknowledge that construction and engineering calculations can depend on project-specific information that may not be available to a general online calculator.
## 1. General Information
5iBuild provides online tools intended to help users perform common construction and civil engineering calculations.
These tools may include calculations relating to:
* Construction costs
* Concrete
* Cement
* Sand and aggregate
* Brickwork
* Mortar
* Plaster
* Tiles
* Steel
* Reinforcement
* Paint
* Area
* Volume
* Wall measurements
* Staircases
* Roof pitch
* Water tanks
* Excavation
* Unit conversion
The results are intended to assist with preliminary planning, learning and estimation.
## 2. Calculator Results Are Estimates
A calculator result is not automatically a final project quantity, price, design or approval.
Results can vary because of:
* User input
* Measurement errors
* Unit selection
* Rounding
* Material dimensions
* Product specifications
* Construction methods
* Material wastage
* Workmanship
* Site conditions
* Local practices
* Project design
* Applicable standards
* Local regulations
Users are responsible for checking whether the assumptions used by a calculator are suitable for their specific project.
## 3. No Guarantee of Accuracy for Every Project
5iBuild aims to provide useful and understandable calculations, but no generic calculator can account for every condition encountered on a real construction project.
A result that is mathematically correct under a stated formula may still be unsuitable for a particular project because the project may require different assumptions or professional design inputs.
For this reason, calculator results should be treated as preliminary unless the relevant project documentation confirms otherwise.
## 4. Professional Engineering Verification
5iBuild is not a substitute for professional engineering, architectural, surveying, quantity-surveying, construction or other regulated professional services.
Appropriately qualified professionals should verify calculations that may affect:
* Structural safety
* Structural design
* Reinforcement design
* Foundation design
* Geotechnical decisions
* Electrical safety
* Fire safety
* Plumbing design
* Accessibility
* Building-code compliance
* Planning approval
* Other regulated or safety-critical matters
Users should follow the requirements applicable to their project location and project type.
## 5. Structural Calculations
Any structural calculator or structural-related information provided by 5iBuild should be treated as preliminary or educational unless the page specifically states otherwise.
Structural design may require consideration of factors such as:
* Loads
* Load combinations
* Material properties
* Member dimensions
* Reinforcement
* Support conditions
* Deflection
* Stability
* Seismic effects
* Wind effects
* Soil conditions
* Durability
* Fire requirements
* Applicable design codes
A generic website calculator cannot automatically consider all project-specific design conditions.
Never use a general calculator alone to approve or construct a safety-critical structural element.
## 6. Construction Cost Estimates
Construction cost calculators are preliminary budgeting tools.
Actual costs may vary because of:
* Location
* Material prices
* Labour rates
* Taxes
* Transportation
* Site access
* Building specification
* Structural system
* Finishing level
* Contractor pricing
* Market conditions
* Project duration
* Date of quotation
For important financial decisions, obtain current quotations and project-specific estimates from appropriate professionals or suppliers.
## 7. Material Quantity Estimates
Material quantity calculators may use general factors or assumptions.
Actual quantities can differ because of:
* Product dimensions
* Construction technique
* Design
* Openings
* Wastage
* Cutting
* Breakage
* Overlap
* Joint sizes
* Surface condition
* Workmanship
Users should use approved drawings, specifications, bills of quantities, mix designs and manufacturer information where available.
## 8. Product Coverage and Manufacturer Information
Calculators involving products such as:
* Paint
* Tiles
* Cement
* Waterproofing
* Insulation
* Adhesives
* Construction chemicals
* Other manufactured materials
may depend on manufacturer-specific product information.
Where a product manufacturer provides a coverage rate, installation instruction or technical specification, that information should be treated as more appropriate for the specific product than a generic planning assumption.
## 9. Unit Conversion
5iBuild provides common engineering and construction unit conversions.
Reasonable care is taken with standard conversion relationships, but users should confirm the units required by their project documents.
Errors can occur when values are entered in inconsistent units.
Before using a converted value in an important document, drawing or calculation, verify the unit and magnitude.
## 10. Standards and Regulations
Construction and engineering requirements vary by jurisdiction.
Different countries, states, provinces, municipalities and project authorities may apply different:
* Building regulations
* Structural standards
* Safety requirements
* Accessibility requirements
* Fire requirements
* Environmental rules
* Planning requirements
* Construction practices
5iBuild does not automatically guarantee compliance with any particular country’s or jurisdiction’s standards.
Users are responsible for determining which standards and regulations apply to their project.
## 11. Engineering Guides and Educational Content
Articles and guides published on 5iBuild are intended to explain general calculation concepts and construction topics.
They should not be interpreted as project-specific professional advice.
Where a guide discusses a standard, formula, construction method or engineering practice, users should verify the current source and applicability to their particular project.
## 12. Third-Party Information
5iBuild may link to external websites, manufacturers, standards organizations, educational resources or other third-party sources.
5iBuild does not control third-party content and does not guarantee:
* Its accuracy
* Its completeness
* Its availability
* Its current status
* Its suitability for your project
Users should review the original source before relying on external information.
## 13. User Responsibility
Users are responsible for:
* Entering correct information
* Selecting the appropriate unit
* Reviewing assumptions
* Understanding the formula
* Checking results
* Verifying important calculations
* Complying with applicable regulations
* Obtaining professional advice when necessary
5iBuild should be treated as a supporting tool rather than the sole basis for an important construction or engineering decision.
## 14. No Professional Relationship
Use of 5iBuild does not create:
* An engineer-client relationship
* An architect-client relationship
* A contractor-client relationship
* A surveyor-client relationship
* A quantity-surveyor relationship
* A consulting relationship
The website provides general information and online calculation tools.
## 15. No Guarantee of Website Availability
5iBuild aims to maintain a reliable website, but we do not guarantee that:
* Every calculator will always be available
