Gotthard Base Tunnel (Rail Tunnel) Design Engineering, Construction & Cost
It is one of the most extreme engineering projects in World History, to build a 35 miles long tunnel under the Alps Mountains. It is the longest tunnel in the world. This could not be possible without world’s strongest drilling machines, each more than 3 stories high and longer than 4 football fields, drilling 24hrs a day for 6 years. The project costed $7 Billion.
New Woodrow Wilson Bridge Construction Project
The Woodrow Wilson bridge spans the Potomac River on the outskirts of Washington DC and connects the states of Maryland and Virginia. The bridge carries the I-95, the most heavily traveled road on the East cost of the United States. The Woodrow Wilson Bridge is 6,736 feet (2,053 m) long and 70 feet (21 m) high.
Seismic Design & Earthquake Resistant Construction
Earthquake resistance is the ability of the structure to withstand earthquakes. These structures perform better during the earthquakes and give sufficient time to its dwellers to evacuate the building, besides saving lives, reducing injuries and lowering the damages of the earthquake. These structures are intended to withstand the largest earthquake of a
Earthquake Safe Construction Guidelines
If Vulnerability is reduced, risk of disaster will decrease. Prediction of earthquake only saves human losses not economic losses due to collapse. Most of earthquake occurs in ocean. Earthquake of Magnitude 6 evolves energy that is equal to 1 Hiroshima atomic bomb. Magnitude 7 ==> 100x Energy evolved = 1 Hiroshima atomic bomb. Magnitude 8 ==> 100 x
Selection of Stones for Building Construction
Once a stone has been selected on aesthetic basis, it is important than to ensure whether it exhibits the necessary physical properties and durability to remain in working condition for a long time. Confirm the traditional name of the stone and test it in the field for properties like streak, color, hardness etc. It is better to confirm whether the amount and quality of stone
Structural & Non Structural Defects in Building Construction
Concrete is very versatile material. It can be cast in place with or without reinforcement. It can also be precast or prestressed in order to achieve the required strength. In order to achieve the required strength. There is the need of proper understanding of its behavior and constituents that are making the concrete. Any type of negligence in any of its phase like placement, design & maintenance
Retaining Wall - Definition and Types of Retaining Walls | Ret Wall
A retaining wall is a structure that retains (holds back) any material (usually earth) and prevents it from sliding or eroding away. It is designed so that to resist the material pressure of the material that it is holding back. An earth retaining structure can be considered to have the following types: Pre-stressed retaining wall Gravity Walls Reinforced Gravity Walls Concrete Cantilever retaining wall Counter-fort / Buttressed retaining wall Precast concrete retaining wall Prestressed retaining wall
Pile Foundation - Design, Construction and Factors Affecting Piles
In foundation practices, the main point of concern is bearing capacity of soil. Bearing capacity can be defined as the maximum load that can be carried by the soil strata. When the soil is strong enough that it can carry the whole load coming on it, then we use shallow foundation. Shallow foundations are usually used where hard soil strata is available at such a depth
Millau Viaduct Bridge Design, Construction & History
Millau Viaduct multiple span single line cable stayed Bridge the tallest bridge in the world. Its highest tower stretches a staggering 343 meters in height and 2.5 km in length. It is located in southern France, and is the highest bridge in the world. It is a truly amazing piece of engineering, especially considering the method used to span the distance between
Hong Kong International Airport Design & Construction
Hong Kong is one of the wealthiest cities in the world. Previously, it had an airport named Kai Tak. But that was in the middle of the city, endangering human life and property. It had only one run way and the congestion was a lot rather increasing day by day. The airplanes had to fly past the apartments and the tall buildings, very nearly and risk of accident was very high. A new
Design & Construction of Steel Structures
it is the ability to redistribute the load. Simple beam is determinate. Fixed beam is indeterminate by 2 degrees so it has two redundant actions. fixed supported beam is more better as indeterminate structure can redistribute the load. When load increases support becomes plastic and it turns into a simply supported beam. But simply supported does not go through the stage of plastic
Construction of Open Wells
A water well is a lot more than a drilled hole, but for many people, the above ground part of the drilling process is the only part they see. A water well is a specially engineered hole in the ground; For ground water monitoring, or for scientific research purposes, wells may be drilled in a way that allows the specialists to closely examine the rock formations and take frequent
Tutorial: Steps to create a WBS in Primavera
Click "Data" from Menu and then select "WBS", then click the "Structure" button. the numbers from 1 to 10 represent levels of WBS. Which means the structure of WBS can have levels ranging from 1 to 10. Enter the symbol in separator field that you want to use for separating different levels of the WBS. Example of work breakdown structure of a GIS Project in Primavera Project Planner P3.
Types of Floors and Methods of Construction of Floors
A floor is the bottom surface of a room or vehicle. Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. A lot of variety exists in flooring and there are different types of floors due to the fact that it is the first thing that catches your eye when you walk into a house, as it spans across the length and
