340. Free Download of Mechanical and Electrical Construction Design Drawings for a 3-Story House

This is a complete and professional set of Mechanical and Electrical (M&E) construction design drawings for a typical 3-story residential house. The entire document set is scientifically structured, clearly divided into two main parts: the Electrical System and the Water Supply & Drainage System, ensuring all necessary information is provided for the construction process.

The Electrical System section comprehensively covers all items from the general overview to specific details. This part begins with general documents such as technical specifications, a list of drawings, and a legend of symbols. It is followed by schematic diagrams for the main distribution board and for essential Extra-Low Voltage (ELV) systems like the Internet and security cameras. The core of this section consists of layout plans detailing the placement of lighting fixtures, power sockets, air conditioners, and other ELV devices for each floor. Furthermore, the set includes crucial safety details for the earthing and lightning protection systems for the entire building.

The Water Supply & Drainage System section is presented with similar detail. 3D isometric schematic diagrams visualize the entire routing of fresh water supply pipes and pipes for wastewater and rainwater from the roof down to the main system. The floor plans accurately show the location and diameter of each pipeline on every level, thereby positioning the sanitary fixtures. The set also includes detailed installation drawings for common fixtures like lavatories, toilets, and floor drains, as well as details for pipe penetration waterproofing, ensuring the system operates efficiently and sustainably.

In summary, this is an exemplary, complete, and ready-to-use M&E design package for construction, helping to ensure accuracy, safety, and efficiency for the house.
