Hvac Estimate Takeoff
Skill by bsinriclawd
Why use this skill?
Use the HVAC Estimate Takeoff skill for OpenClaw to quickly extract equipment counts and mechanical schedules from PDF blueprints into structured tables.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/bsinriclawd/hvac-estimate-takeoffWhat This Skill Does
The HVAC Estimate Takeoff skill, developed by bsinriclawd, is a specialized OpenClaw agent capability designed to automate the labor-intensive process of quantity surveying for heating, ventilation, and air conditioning systems. By utilizing the pymupdf-pdf tool, this skill programmatically parses architectural and mechanical engineering PDF plans to extract critical data points, including equipment counts, ductwork specifications, and mechanical schedules. It transforms static blueprint information into structured, actionable tables, allowing professionals to generate accurate project estimates significantly faster than manual methods.
Installation
To integrate this skill into your OpenClaw environment, execute the following command in your terminal:
clawhub install openclaw/skills/skills/bsinriclawd/hvac-estimate-takeoff
Once installed, the skill automatically registers the file_upload trigger. Ensure that your PDF plan files are legible and, if possible, formatted as vector-based PDFs for the highest extraction accuracy.
Use Cases
- Residential and Commercial Estimation: Quickly identify the number of air handlers, condensers, registers, and diffusers required for a new build or retrofit project.
- Mechanical Schedule Audits: Cross-reference equipment schedules found in PDF footnotes with layout drawings to ensure consistency in your bid proposals.
- Rapid Bid Preparation: Accelerate the quoting process for HVAC contractors who need to respond to tenders or RFPs with tight deadlines.
- Inventory Planning: Generate a high-level bill of materials (BOM) during the pre-construction phase to assist with procurement scheduling.
Example Prompts
- "Upload the attached HVAC_Mechanical_Plans.pdf and create a table summarizing all the VAV units and their associated airflow requirements."
- "Extract the equipment schedule from this plan and format it into a table so I can easily count the total number of diffusers needed for the second floor."
- "Analyze the mechanical layout provided in this file and list all rooftop units and their cooling capacities in a structured table format."
Tips & Limitations
To maximize the effectiveness of this skill, ensure that the input PDF files are clear and not overly compressed or flattened images, as OCR performance can vary. While the skill is excellent at identifying textual schedules and equipment labels, complex, overlapping schematics may occasionally require manual verification. Always review the resulting table against the source blueprint before finalizing any commercial contracts or purchasing orders. Large-scale projects with hundreds of pages should be uploaded in sections to ensure the context window remains focused on the relevant mechanical sheets.
