It also outlines three types of personal fall protection systems: work positioning systems that prevent or limit falls, such as boatswain's chairs; rope access systems that use two ropes for safety and access; and fall arrest systems that limit the impact of a fall through harnesses and high anchor points. Regular inspections of equipment are recommended.
Tunneling Construction - NATM
The New Austrian Tunneling Method (NATM) involves:
1) Creating initial support on tunnel openings to prevent deterioration.
2) Excavating in short sections and applying shotcrete and metal supports.
3) Monitoring deformation with various instruments to ensure tunnel stability.
What is Civil Engineering
Civil engineering designs and builds structures like bridges, roads, and overpasses. Civil engineers study materials, soil characteristics, wind patterns, and a construction site's intended use to design and oversee all phases of construction projects. They develop and size structures and heating systems and specify the materials used based on collected data. Civil engineers also work in offices managing teams, costs, safety, health, and environmental compliance. The field offers opportunities in areas like civil engineering, urban design, roads, highways, railways, airports, ports, and viaducts.
Woman's bridge
The Puente de la Mujer bridge in Buenos Aires, Argentina was designed by Spanish architect Santiago Calatrava. Completed in 2001, it is a cantilever cable-stayed bridge with an asymmetrical design representing a couple dancing tango. Notable features include a single stabilizing pylon at a 45 degree angle, and a central rotating section that opens 90 degrees to allow water traffic to pass through, taking less than two minutes to open. At 170 meters long with a central rotating span of 102 meters, it is one of Calatrava's few works in South America.
Successful construction with PERI
The document summarizes a building rehabilitation project in Lisbon, Portugal where PERI scaffolding was used. The scaffolding was installed along Avenue da Republica, standing 59 meters tall with a total area of 3342 square meters. A team of 12 PERI workers assembled the 63091 kg scaffolding over 3 weeks, erecting approximately 18.56 square meters per day per worker. Photos show the installed scaffolding used to rehabilitate the building safely along the busy pedestrian street.

- 2. Instituto Superior de Engenharia de Lisboa – English 2012/2013 What is a green roof ? A green roof or sometimes called living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. There are two types of green roofs: Intensive roofs, which are thicker and can support a wider variety of plants but are heavier and require more maintenance.

- 6. Instituto Superior de Engenharia de Lisboa – English 2012/2013 Some disadvantages… The main disadvantage of green roofs is the higher initial cost of the building structure, waterproofing systems and root barriers. The additional mass of the soil substrate and retained water can require additional structural support. Some types of green roofs do have more demanding structural standards especially in seismic regions of the world. Some existing buildings cannot be retrofitted with certain kinds of green roof because of the weight load of the substrate and vegetation exceeds permitted static loading. Depending on what kind of green roof it is, the maintenance costs could be higher, but some types of green roof have little or no ongoing cost. Some kinds of green roofs also place higher demands on the waterproofing system of the structure, both because water is retained on the roof and due to the possibility of roots penetrating the waterproof membrane.
