Project description
This project involved a comprehensive electrical estimation for a multi-level residential property, covering the ground floor, first floor, and an additional shed structure. The scope included detailed quantity takeoffs for wiring systems, lighting fixtures, power outlets, and specialized electrical components, ensuring full coverage of all functional and design requirements.
The estimation required careful interpretation of electrical drawings (SK-101, SK-102, SK-103) to accurately quantify wiring lengths, fixture counts, and device placements. A wide range of electrical elements were included, such as recessed lighting, pendant fixtures, emergency lighting, USB-integrated sockets, and external lighting systems. Special consideration was given to both interior and exterior electrical layouts to ensure efficiency, safety, and compliance with modern residential standards.
Additionally, the project incorporated advanced electrical provisions such as TV/data points, heated mirror systems, kitchen appliance connections, and outdoor lighting features. The takeoff was structured to support precise cost calculation, covering labor and material components, along with provisions for contingencies and contractor overheads, making it suitable for bid-level submission.
