Preface

When preparing cost estimates or material plans for MEP (Mechanical, Electrical, and Plumbing) installation projects, the common practice is to manually measure circuit by circuit against the drawings and then fill in the checklist by hand. The problem is not the inability to calculate, but the inconsistency in standards: this time items are categorized by circuit, next time by system; cable reserves are sometimes counted and sometimes not. Ultimately, the figures do not match the detailing or the final settlement. The Skill introduced below aims to solidify this process into a reproducible workflow—taking DWG or scanned index files as input and outputting two sets of standards: a cost estimate draft list and a material plan draft. It explicitly excludes monetary amounts from its output.

What is this

Skill Name: MEP Quantity Surveying · Dual Standards for Cost Estimate Drafts and Material Plans, located at @user_43faedd6/anzhuang-suanliang. It is published and maintained by user_43faedd6, version 0.4.27, sourced from the community, and categorized as professional. It is positioned as a pre-processing tool for quantity surveying in MEP projects, solving the problem of quickly generating quantities and drafts once drawings are available.

Core Functions

According to the official description, the capabilities are as follows:

  1. Extracts cost estimate draft lists and material plan drafts from MEP DWG files or scanned indexes.
  2. Categorizes pipelines by circuit specifications, grouping pipe segments of the same circuit into the same category to avoid mixed calculations.
  3. Expands wire cores and reserves, meaning it calculates wire lengths by circuit and includes reserved amounts.
  4. Estimates quantities for cables, trays, plumbing, sprinklers, supports, and equipment, covering multiple disciplines (Plumbing, HVAC, and Electrical).

The output is positioned for four purposes: cost estimation quantity surveying, material planning, drawing review quantity checking, and cross-verification with results from specialized software.

Installation and Activation

This Skill is based on the general SKILL.md format and does not require an API Key (tag: requires_api_key=false). It has been published on SkillHub at the following addresses:

https://www.skillhub.cn/skills/user_43faedd6/anzhuang-suanliang

https://api.skillhub.cn/user_43faedd6/anzhuang-suanliang

It should be noted that existing public materials only provide the SkillHub page and API address; they do not list specific installation commands, directory conventions, or configuration file fields, nor do they distinguish the activation methods for Cursor, Codex CLI, or Claude Code. This part should be subject to the official page, and this article makes no speculations.

Typical Usage

The input and output relationships provided in the official materials are as follows:

Input: MEP DWG drawings or scanned index files.
Processing: Categorizes pipelines by circuit specifications, expands wire cores and reserves, and estimates quantities for cables, trays, plumbing, sprinklers, supports, and equipment.
Output: One cost estimate draft list and one material plan draft.

In actual use, it is recommended to proceed in two steps: first, run a pass to generate the cost estimate draft to check the standards against the drawings and lists; second, organize the material plan draft based on the same results to directly interface with procurement. Since both deliverables come from the same extraction, the quantities are consistent and will not conflict.

Applicable Scenarios & Cautions

This tool is suitable for the following personnel: engineers doing MEP cost estimation, material planners needing to prepare materials in advance, checkers performing rapid quantity verification for drawing reviews, and those wishing to cross-verify results with specialized quantity surveying software.

Boundaries must be clear: It does not replace detailing (翻样), cut-off lists (下料), or settlement (结算), nor does it output monetary amounts. That is to say, the calculated quantities can be used for proofreading and comparison, but cannot be used as the final basis for cutting materials, nor can they be used directly for quotations. Parts requiring node refinement, such as conduit lengths and the weight of steel profiles for supports, still need to be processed in the detailing stage.

Additionally, please note that this is a community work sourced from community, not an official vendor plugin. Before using its output for formal delivery, it is recommended to perform a manual review of critical circuits.

Conclusion

The value of this Skill lies not in absolute calculation accuracy, but in fixing the standards: a single extraction produces two sets of quantities—a cost estimate draft and a material plan—which hold true for quantity surveying, material preparation, drawing review, and software result comparison. The positioning is also very clear: detailing, cut-off lists, settlement, and monetary amounts are not its responsibility.
