What is Construction Quote & Job Costing Calculator?
This Openclaw Skills extension empowers contractors and tradespeople to transform simple job descriptions into comprehensive, itemized quotes. By leveraging current 2025/26 UK material prices and trade-specific labor rates, it eliminates the guesswork in project estimation. Whether you are pricing an extension, a kitchen refurbishment, or a loft conversion, this skill provides a structured framework to ensure every screw, beam, and labor hour is accounted for.
The tool bridges the gap between technical job requirements and professional client communication. It doesn't just provide ballpark figures; it generates a complete working estimate that includes material breakdowns, labor days, regional price adjustments, and a formatted client-ready document including payment schedules and terms and conditions.
Construction Quote & Job Costing Calculator Use Cases
- Residential builders needing quick, accurate estimates for extensions, loft conversions, or garage conversions.
- Specialist tradespeople such as electricians, plumbers, and plasterers requiring itemized material lists for procurement.
- Contractors creating professional, client-ready quotation documents that maintain profit margins.
- Estimating regional price variations for jobs across different UK locations, from London to the North West.
- Landscapers and driveway specialists needing to calculate linear meter or square meter pricing for paving and fencing.
How Construction Quote & Job Costing Calculator Works
- The user describes a construction job using natural language, including as much detail as possible about the scope and dimensions.
- If essential details are missing, the skill asks up to four targeted questions regarding size, specification level, and location.
- Openclaw Skills processes the input to generate a detailed internal material list with low and high price estimates based on current merchant rates.
- A labor breakdown is calculated based on trade-specific day rates and estimated duration for each phase of the project.
- The skill applies regional multipliers and adds necessary auxiliary costs like skip hire, scaffolding, and professional fees.
- A final internal summary is produced, including waste allowances and profit margins, followed by a separate, professional document formatted for the end client.
