Smart Connected Buildings
Smart connected buildings are revolutionizing how we manage and interact with our built environments. These buildings integrate various systems—such as HVAC, lighting, security, and fire alarms—into a single, cohesive network, enhancing efficiency, safety, and comfort.
Integration and Automation
Traditionally, building systems operated independently. Smart connected buildings use IoT to integrate these systems, allowing them to communicate and work together. For example,

Soil Compaction and Construction Equipment
Soil Compaction
Soil compaction is the process of increasing the density of soil by reducing the air voids. This is achieved by applying pressure or vibration to the soil. Compaction is essential for ensuring the stability and load-bearing capacity of soil in construction projects.
Types of Soil Compaction
- Static Compaction: This method involves applying a constant pressure to the soil using rollers or tampers.
- Impact Compaction: This method involves using a
ITC-11 Electrical Distribution Network Installation Guide: Rush
ITC-11
1. RUSH
1.1. Definition
Part of the installation of the distribution network, which feeds the box or general protective boxes or functional equivalent unit (hereinafter GPC).
1.2. Types of Rush
Based on its design, system installation and network features, the rush may be:
| TYPE | SYSTEM INSTALLATION |
|---|---|
| Air | Posada on facade Stretched over pole |
| Underground | With input and output Shunt |
| Mixed | Aero-Ground |

Components of Spatial Structures (Steel Mesh)
Steel Profiles
Steel profiles (hot or cold-rolled) may have different sections:
- Open profiles: I, M, U, L
- Closed profiles: Circular, square, and others
Knots (Connections)
The connections are key to achieving a stable structure. Several methods exist:
- Welding: Requires extensive non-destructive testing to ensure proper execution.
- Screws: Transmit applied forces, supporting shear or reactions in the section. The usual practice is to place 2 screws per connection.
