The dataset is provided by the New York City Department of Buildings (data.cityofnewyork.us) and includes multiple rows per job filing to detail work on different floors or for different electrical components. It was last updated in April 2026.

Use Cases

• Analyze the distribution of electrical load by calculating average Total_KW and Total_Watts_VA per Job_Filing_Number.
• Forecast material demand by correlating Material_Gauge and AWG specifications with Quantity and Cost across projects.
• Classify types of electrical installations using Work_Description, Item, and Fixture columns to identify common renovation scopes.
• Assess project complexity by counting the number of unique Floor_ID or Work_ID entries associated with a single Job_Filing_Number.

Strengths
