Why Foundation Is Important For Substructure In Construction?

The substructure of a building transfers the load of the building to the ground and isolates it horizontally from the ground. This includes foundations and basement retaining walls. It is differentiated from the superstructure. It safeguards the building against the forces of wind, uplift, soil pressure etc.

What are the components of a substructure?

The basic components of a building substructure are the foundation and plinth beam. These components safely transfer the load from the superstructure to the ground.


  • Strip Foundation (Shallow Foundation)
  • Raft Foundation (Shallow Foundation)
  • Pile Foundation (Deep Foundation)

What is the main purpose of a superstructure?

A superstructure (the bridge deck) is an upward extension of an existing structure above a baseline called ground level and it usually serves the purpose of the structure’s intended use. Building parts located above ground such as the column, beam, floor, roof, etc.

Is known as substructure of the building?

The floor of a building immediately above the ground is known as the ground floor. … Explanation: Substructure or foundation is the lower portion of the building which lies below the plinth level. Substructure transmits loads of the superstructure to the supporting soil.

What is meant by substructure and superstructure of a building?

The two major components of buildings are the substructure and superstructure. The substructure is the part of the building that is underneath the ground, while the superstructure is everything that is above ground.

What are the primary elements of substructure?

The substructure elements are as follows: Abutments, wingwalls, and approach slabs—Connect the bridge structure to the roadway embankment. Pier caps and cross-beams—Transfer loads to columns or piles. Piers, bents, and columns—Transfer loads to foundation interface elements.

What are the types of substructure?

Substructure Construction

  • Piers.
  • Accelerated Bridge Construction.
  • Cast-in-Place.
  • Precast Concrete.
  • Prefabrication.
  • Self-Propelled Modular Transporter.
  • Abutment.

What is the difference between a substructure and foundation?

As nouns the difference between foundation and substructure

is that foundation is the act of founding, fixing, establishing, or beginning to erect while substructure is the supporting part of a structure (either physical or organizational; the foundation).

Why is flexibility important for structures like buildings?

Design flexibility can allow a building to evolve over time as the user needs change. The flexibility of a building or elements of its design can allow it to be used efficiently despite changes in operational requirements, whereas an inflexible building might become obsolete.

Why footing is important for a building?

Footings are the most important part of foundation construction. The purpose of footings is to support the foundation, prevent settling, and is crucial to providing the proper support for the foundation and ultimately the structure.

Why a foundation is important?

What is the Main Purpose of a Foundation? A proper foundation does more than just hold a house above ground. Building foundations also keep out moisture, insulates against the cold, and resists movement of the earth around it. Oh, and one more thing: It should last forever.

What are substructure walls?

Substructures are foundations, pile caps or underground concrete beams. Retaining walls are structures which are designed to retain soil and slopes. This happens when there is a change to the elevation of the ground.

What substructure works are carried out by civil engineers?

Civil Engineering

  • Top-down deconstruction.
  • Substructure demolition.
  • Enabling/ground works.
  • Temp works.
  • Deep multi storey basement excavations.
  • Obstruction clearance.
  • Contiguous/Secant/Sheet piled walls.
  • Bearing Piles (cfa)

What is superstructure What does it need?

Answer: A superstructure is an upward extension of an existing structure above a baseline called Ground Level in general and it usually serves the purpose of the structure’s intended use. In Buildings, the portion of the structure that is above ground level that receives the live load is referred to as Superstructure.

What substructure means?

: an underlying or supporting part of a structure.

What are substructure works?

It defines the term substructure as: … ‘All work below underside of screed or, where no screed exists, to underside of lowest floor finishes including damp-proof membrane, together with relevant excavations and foundations (includes walls to basements designed as retaining walls).

How many types of parapets are there?

How many types of parapets are there? Explanation: The 4 types are plain, perforated, panelled and embattled.

Why footing is provided?

Footing is a part of foundation which is constructed with concrete or brickwork masonry and acts as a base to the floor columns and floor walls. The main function of footing is to transfer the vertical loads directly to the soil. The term footing is used in conjunction with Shallow foundation commonly.

What is the most important part of construction?

Planning. Detailed and strategic planning is the most important aspect of successful construction project management. The more complex the project, the more planning will be required.

What is the purpose of sill bolts?

Photo 1 shows a type of steel anchor bolt that is commonly used to connect wood sill plates to concrete or masonry foundations. These anchor bolts are set in place when the foundation wall is poured (or the concrete block foundation wall is grouted) with the threaded end up.

Why does a tall building need to be flexible?

While skyscrapers might appear to be highly-strengthened, immovable structures, all tall buildings are in fact designed with a degree of flexibility in mind. This is principally due to the impact that wind forces – known as “wind loads” – have on a building as it becomes taller.

What does flexibility mean in psychology?

Psychological flexibility is defined as being in contact with the present moment, fully aware of emotions, sensations, and thoughts, welcoming them, including the undesired ones, and moving in a pattern of behavior in the service of chosen values.
