All other dimensions are provided in drawing.

STRUCTURAL DRAWINGS:

• Excavation or trench plan
• Footing and column layout with reinforcement
• Column schedule with reinforcement details
• Plinth beam layout with reinforcement details
• Floor to floor beam and slab layouts
• Liftpit and headroom reinforcement detail

Excavation or trench plan:

• On-site excavations or execution of Trenches for Sub-Structure of the building requires a plan where all the trenches are marked according to Grid of centreline markings and the offsets of dimensions respectively.
• Trench Plan highlights the dimensions (Length, Breadth, Depth) of trenches to be to excavated with reference to Centreline Grid.
• It is required at an early stage, immediately after marking Centreline on-Site.

Footing and column layout with reinforcement

Column schedule with reinforcement details

Plinth beam layout with reinforcement details

• It is used for marking the Tie beam (Primary element for ‘Earthquake Resistant Structure’) which is used for connecting the columns emerging from the Sub-Structure (structure beneath the ground level) of the building.
• This layout gives the orientation of the Tie Beam to the column and also the Cross-section sizes with specifications of the design.

Floor to floor beam and slab layouts

• It includes the layout of roof slabs concerning the corresponding beam by the Centreline Grid Markings of Columns-Beams.
• This involves the orientation of the roof slab and Reinforcement Bar Details to be incorporated according to Structural Design.
• Details like diameter and number of reinforcement bars in a defined length are mentioned in roof slab layout for structural stability.

Liftpit and headroom reinforcement details

• The reinforcement details for liftpit and headroom is given separately.

CALCULATION OF LOAD FOR INDIVIDUAL ELEMENT OF BUILDING ACCORDING TO IS CODE:

Dead load calculation:

Assume, unit weight of rcc column, beam and slab = 25 KN/m3

Unit weight of brick wall = 20 KN/m3

For column:

Height of column is 4.5m.

C/s given as = 300*300mm

Unit weight of RCC column = 25 KN/m3

Total weight of concrete = 4.5*0.3*0.3

= 0.405 m3

Self weight of column = 0.405* unit weight of column

= 0.405*25

= 10.125 KN

Total load due to column = no. of column* self weight of column

For beam:

c/s given as = 300*450mm

Unit weight of RCC beam = 25 KN/m3

Total weight of concrete = 0.3*0.45

= 0.135

Self weight of beam = 0.135* unit weight of beam

= 0.135*25

= 3.375 KN/m

For slab:

Thickness of slab = 125mm

Load of slab for 1m2 area = 0.125*Unit weight

= 0.125*25

= 3.125 KN/m3

For wall:

Height of wall = 4.5m

Suppose thickness of wall = 230mm, 110 mm

For brick thickness = 230mm

Load due to brick wall per unit length = unit weight of brick wall* volume of brick wall

= 20*0.230*4.5*1

= 20.7 KN/m

For brick thickness = 110mm

Load due to brick wall per unit length = unit weight of brick wall* volume of brick wall

= 20*0.110*4.5*1

= 9.9 KN/m
