to a 5 Story building.
Part A
1. Introduction
The population of the world is increasing day by day. As a result, the population density is
increasing rapidly and decreasing the cultivation land and forest area for construction of
residential and commercial building. But land is fixed. When it is necessary to stop decreasing
the cultivation land and forest area, there is a problem arising. This problem is accommodation
problem. There is arising office building space problem and it can be solved by reconstruction of
existing building. This project deals with typical four storied commercial building to be extended
up to 5 stories. This project will act as a guideline for future works with above location for
similar multistoried high rise building. It will also give an idea about comparative study between
mat foundation & pile foundation for different works of the above proposed area. Professional
engineers, organizations may avail this project as a guideline for effective, economic and
convenient design of multistoried building in suitable storey.
Feasibility Study
The subject property is situated within The Moor, Sheffield. The Moor is currently going through
a rapid period of transformation with the new markets block opening in November 2013 and a
number of other blocks being in the process of redevelopment. The premises form part of a four
storey building situated on a prominent corner at the junction on the Moor, Sheffield. The
property comprises a four storey building with retail accommodation at ground floor and the
office accommodation over the first, second and third floors of the building. The Building is
surrounded by the retail hustle and bustle of the city centre shopping precincts and there are a
number of car parks located in the immediate area

Structural Options
Structural options are the most important things for building and economy. We will find the best
structural solution of the proposed building. At first we will discuss about some structural oftion

5. for the building.
Fig; Floor plan of the building.

6. Option 1 - Concrete structure (Mention Why did i choose this for the project)
The ground floor office area is to provide a 24 m by 22 m area with no internal columns. Stairs
locations are as shown in drawing. A 15.5 m wide public area is required at first floor, running
along the entire length of the building. Clear headroom of 3m is required for the public. No part
of the structure shall be higher than 6 m above the ground level. Perimeter columns shall not be
spaced closer than 4m.So; we can use concrete structure as proper solution for the entire
building. All beams and columns should be RCC structure. Brick walls and zed cladding board
panel and steel bracing will be used for covering the entire building. Here, foundation is the main
problem for reconstruction .From the bore hole data it is clear that it is on clay layer, So
consolidation occurred here and this soil is strong enough now to carry extended building load.
So, previous foundation is ok for this reconstruction. But, to ensure safety we will use roof truss
in upper floor to minimize the dead load. So, no, huge load will be added here. only few walls
load and lightweight rood truss load will be added here. For roof we should use roof truss
because it will be safe and cheaper solution for entire building. So, truss solution is the proper
solution for this building. Roof truss will carry wind load and total roof load and will transfer it
to beams and then beams will transfer this load to column and column will transmit this load to
foundation. Single strip footing can be used here and no pile will be required. The First stage
assessment of the risk of damage to buildings and structures in tunneling zones involved
preparation of settlement profile induced by tunnel excavation. Settlement was computed at
every 100m interval along tunneling alignment using the method based on the Gaussian normal
distribution curve presented above. Settlement induced by each tunnel was predicted
independently and superimposed to determine the total settlement induced by the twin
tunnels.10mm and 25mm settlement contours were plotted in the topography plan.

Option 2 - Steel Structure (Why this is not chosen for the project)

RCC structure. Brick walls and zed cladding board panel and steel bracing will be used for
covering the entire building

Selection of Structural strategies:
So, we will use option 1 for construction. Walls and columns should be constructed and roof will
be constructed by roof truss. This building is a steel structured building. Roof trusses have been
used at the roof level. Beams and columns are jointed together. So, it is a steel framed structure.
There is some extension of the building floors. The main part of this building is foundation.
Here, it is a RCC framed structure and high rise building. So, foundation is critical here in this
building.
Conclusion
The sub-soil exploration has been performed at the proposed site for the construction of the
area. Three boreholes of 45-ft. depth from the existing ground level were drilled. Based on
the information obtained from sub-soil test results, both in the field and laboratory, it may
be concluded that the sub-soil condition is good from, approximately, 30 ft below the
existing ground level upto the bottom of boring. For buildings of standard occupancy upto
2-3 stories, spread foundation or mat may be used within 4-5 ft from existing ground level.
Attention should be given to settlement calculation. The final selection of type and
dimensions of foundation for the proposed structure is to be decided by the consultant/
designer engineer.
